UMTS phase 1 capabilitiesThis Tdoc shall be used to produce version 1.0.0 of the new specification « UMTS phase 1capabilities » for SMG#26.

1. A phased approach for UMTS

The UMTS system will be defined in a phased approach. This specification addresses the UMTSphase 1 capabilities.

The UMTS phase 1 capabilities are those of GSM phase 2+ release 99 completed by UMTS specificrequirements. These additional requirements for UMTS phase 1 are listed in this specification for thedifferent elements of a high level functional architecture composed of a UMTS mobile station, aUMTS access network and a UMTS core network. The fundamental difference between GSM andUMTS phase 1 resides in the support of high bit rate bearer services with the notion of negotiatedtraffic and QoS characteristics. UMTS phase 1 shall in particular support bursty traffic in an efficientway.

The UMTS mobile station is composed of a USIM and a UMTS mobile termination.

The phase 1 USIM is developed on the basis of the phase 2+ release 99 SIM. When UMTS specificrequirements do not appear, this means that the GSM phase 2+ release 99 specifications for the SIMalready cover the UMTS phase 1 requirements.

The UMTS mobile termination is the component of the UMTS Mobile Station which supportsfunctions specific to the management of the radio interface (Um). No requirements address the mobiletermination itself as it is seen as being partly an element of the UMTS access network and partly anelement of the UMTS core network (it contains protocols which peer entities are ended either in theaccess or in the core).

Regarding the phase 1 UMTS access network, only the UTRAN (including both WCDMA and TD-CDMA radio interfaces) is considered as being part of the UMTS access network. Other types ofaccess networks are for further consideration. UTRAN is a new access network and as such all theUTRAN requirements are defined in this specification. This includes in particular the interoperabilityrequirements put on the UTRAN and GSM BSS access networks to cater with UMTS networksoperating the two types of access networks.

The phase 1 UMTS core network is developed on the basis of the phase 2+ release 99 GSM corenetwork (i.e. the GSM NSS and the GPRS backbone infrastructures). When UMTS specificrequirements do not appear, this means that the GSM phase 2+ release 99 specifications for the corenetwork already cover the UMTS phase 1 requirements. It shall be noted that the advanced bearercapabilities of the phase 1 UMTS access network will not be integrally supported by the phase 1UMTS core network. This however guarantees the viability of the UMTS access network as it isdesigned since phase 1 with the objective of supporting broadband bearer services.


2 / 12

The time plan for UMTS phase 1 is a stable set of specifications for the end of 1999. This time plan isconsidered of primary importance. If the required functionality is considered not feasible to finalisefor the end of 1999, this shall be reported back to SMG1 for a possible redefinition of the contents.

After phase 1, the new capabilities of UMTS shall be defined in annual releases (each releaseconstituting a coherent set of UMTS mobile station, access network and core network specifications).

UMTS phase 2 will be based on annual releases 2000, 2001 and 2002, allowing complete operationalfunctionality by 2005 but partial operation in earlier stages. One fundamental objective of UMTSphase 2 to be taken into account since UMTS phase 1 design is that one possible implementation ofthe UMTS phase 2 core network shall be an integrated infrastructure, and not any more thejuxtaposition of the GSM NSS and GPRS backbone.

NOTE 1 : This specification describes UMTS phase 1 capabilities from a service point of view. Assuch, the terms connection oriented and connectionless always refer to the connection mode requiredby applications. It has nothing to do with the nature of the technology used to provide bearer servicesinside the network.NOTE 2 : The term GSM BSS refers in this specification to the GSM/GPRS access network.NOTE 3 : The term GSM core network refers in this specification to the GSM NSS and GPRSbackbone infrastructures.NOTE 4 : The term UMTS network refers in this specification to a network operated by a singlenetwork operator and composed of :• UTRAN access networks (WCDMA and/or TD-CDMA),• optionally GSM BSS access networks,• a UMTS core network.

2. UTRAN capabilities

NOTE : The term performance refers in this section to the realisation of the QoS objectives inside theUTRAN.

UTRAN capabilities for UMTS are the complete set of bearer capabilities and bearer control specifiedin TS 22.05. The UTRAN shall have the following capabilities :

1. It shall be possible to connect one UTRAN to one and only one UMTS core network. (In the caseof a phase 1 UMTS core network consisting of both a GSM NSS and a GPRS backbone, its shallbe possible to connect the UTRAN to the two types of infrastructures.)

2. The UTRAN shall support the set-up, re-negotiation and clearing of connections with a range of

traffic and performance characteristics. The re-negotiation may result from an upper layer requestor a change in the radio conditions (handover, cell load modification,...) and be mobile station ornetwork initiated. It shall be possible for the UTRAN to apply connection admission controlduring connection set-up and re-negotiation (Connection admission control is a network procedureused to limit the admission of new connections to those which do not compromise the traffic andQoS characteristics of the already established connections). It shall be possible for the UTRAN toapply flow control on a connection during its lifetime (Flow control is a network procedure used toregulate the traffic of a user). It shall be possible for the UTRAN to apply usage parameter controlon a connection during its lifetime (Usage parameter control is a network procedure used to checkthat the traffic contract negotiated between the user and the network is respected by the user).


3 / 12

3. The UTRAN shall support a range of traffic and performance characteristics for the connectionlesstraffic.

4. The range of traffic and performance characteristics that shall be supported by UTRAN for

connection oriented and connectionless traffic is indicated in Annex 1 sections 3 and 4. 5. The UTRAN shall allow one mobile termination to have more than one connection mode

(connection oriented and connectionless traffic) and/or more than one connection simultaneously.It shall be possible for each connection to have independent traffic and performancecharacteristics. It shall be possible for each connectionless message to have independent traffic andperformance characteristics.

6. Seamless handover of one mobile termination connection oriented and connectionless traffic

between cells of one UTRAN shall be supported. This shall result in an imperceptible loss ofspeech (if any) for the user of telephony services and data services with no degradation.

7. At least one class of mobile termination supporting both WCDMA and TD-CDMA radio interfaces

shall be standardised. It shall support monitoring of the two types of cells in idle mode (cellreselection procedure) and active mode (handover preparation procedure).

8. For UMTS networks composed of UTRANs with both WCDMA and TD-CDMA radio interfaces,

the cell selection and the paging procedures shall accommodate to the fact that service areas maybe either covered by WCDMA cells, WCDMA and TD-CDMA cells or TD-CDMA cells.

9. Handover of one mobile termination connection oriented and connectionless traffic between cells

of two UTRANs using different radio interfaces (i.e. WCDMA and TD-CDMA) and operated byone single UMTS network operator shall be supported in both directions. SMG1 seeks SMG2advice on whether it is technically and cost effectively feasible for this type of handover to beseamless.

10. The UTRAN shall facilitate the location of a UMTS mobile termination. It shall be possible for the

location precision to be an UMTS network operator choice, with the precision of the locationvarying from one part of the service area to another. A minimum precision of around 50 metersshall be achieved in all types of terrestrial radio environments. Location requirements are detailedin TS 22.05 section 8.5.

11. The optimisation of the UTRAN radio interface shall be done around the objectives expressed in

TS 22.05 section 5. 12. The USIM requirements defined for later releases of UMTS shall be taken into account in the

design of UTRAN (if having any impact).

3. UTRAN and GSM BSS relationship

There is a special relationship between the UTRAN and GSM access networks as it is expected thatUTRANs will start as islands in a sea of GSM BSS. GSM BSS access networks will be a key elementfor service continuity in UMTS networks. The requirements are the following for UMTS phase 1 :

1. At least one class of mobile termination supporting the GSM BSS and UTRAN radio interfacesshall be standardised. It shall support monitoring of cells belonging to the two types of accessnetworks in idle mode (cell reselection procedure) and active mode (handover preparationprocedure).


4 / 12

2. For UMTS networks composed of both GSM BSS and UTRAN access networks, the cell selection

and the paging procedures shall accommodate to the fact that service areas may be either coveredby GSM BSS cells, GSM BSS and UTRAN cells or UTRAN cells.

3. For UMTS networks composed of both GSM BSS and UTRAN access networks, the handover

procedures in the UTRAN and the GSM BSS shall support handover between GSM BSS andUTRAN cells of connection oriented and connectionless traffic, in both directions (i.e. UTRAN toGSM BSS and GSM BSS to UTRAN). Some traffic flows may be re-negotiated, temporarilyliberated or re-established during these handover procedures because of the different bearercapabilities of the GSM BSS and UTRAN access networks. A detailed list of handoverrequirements needs to be defined service per service by SMG1 (i.e. for all GSM phase 2+ release99 bearer services, teleservices and supplementary services).

4. UMTS Core Network

NOTE : The term performance refers in this section to the realisation of the QoS objectives inside theUMTS core network.

In the first phase of UMTS, the UMTS core network shall be developed on the basis of the phase 2+release 99 GSM core network. The additional requirements for the phase 1 UMTS core network are asfollows :

1. The phase 1 UMTS core network shall support up to 64 kbit/s circuit switched bearer services. 2. The phase 1 UMTS core network shall support packet switched data services of at least 2 Mbit/s

peak bit rate. 3. The phase 1 UMTS core network shall allow to set-up, re-negotiate and clear connections with a

range of traffic and performance characteristics. It shall be possible to apply traffic policy (e.g.connection admission control, flow control, usage parameter control...) on a connection during itsset-up and lifetime.

4. The phase 1 UMTS core network shall support a range of traffic and performance characteristics

for the connectionless traffic. 5. The range of traffic and performance characteristics that shall be supported by the phase 1 UMTS

core network for connection oriented and connectionless traffic shall be in line with GPRS phase2+ release 99. This means that the support of the full set of bearer services defined in Annex 1sections 3 and 4 is not required for the phase 1 UMTS core network.

6. GPRS phase 2+ release 99 point to multipoint communication configurations shall be supported by

the phase 1 UMTS core network. 7. The phase 1 UMTS core network shall allow one mobile termination to have more than one

connection mode (connection oriented and connectionless traffic) and/or more than one connectionsimultaneously. It shall be possible for each connection to have independent traffic andperformance characteristics. It shall be possible for each connectionless message to haveindependent traffic and performance characteristics.


5 / 12

8. In order to facilitate the development of new applications, it shall be possible to addressapplications to/from a phase 1 UMTS mobile termination in connection oriented andconnectionless traffic modes (notion of port).

9. Calls with multiple connections are not supported by phase 1 UMTS core networks. 10. Operator specific services based on the VHE concept defined in TS 22.01 shall be provided by the

phase 1 UMTS core network. This functionality could be provided through available toolkits(CAMEL, MExE and SIM Toolkit).

11. The phase 1 UMTS core network shall support the generation of call data records based on the

traffic (volume, bit rate) and performance provided to the user. 12. The phase 1 UMTS core network shall support on-line billing. Billing of 3rd party value added

services with the concept of one-stop-billing shall be supported by the phase 1 UMTS corenetwork through standardised procedures.

13. The phase 1 UMTS core network shall support both bilateral and automatic roaming agreements

between UMTS networks with improved security as defined by SMG10. 14. The phase 1 UMTS core network shall support interworking with PSTN, N-ISDN, GSM, X.25 and

IP networks with their respective numbering schemes. TR 22.75 addresses this issue in moredetails.

15. It shall be possible for the standardised classes of phase 1 UMTS mobile termination supporting

the GSM BSS and UTRAN radio interfaces to roam in GSM networks and receive GSM services. 16. It shall be up to the UMTS network operator whether or not to accept the use of phase 1, phase 2

and phase 2+ SIM applications as access modules in their network. 17. The USIM requirements defined for later releases of UMTS shall be taken into account in the

design of the phase 1 UMTS core network.

5. USIM

In the first phase of UMTS, the USIM shall be developed on the basis of the phase 2+ release 99GSM SIM. The additional requirements for the phase 1 UMTS USIM are as follows :

1. USIM is the GSM phase 2+ release 99 SIM for UMTS phase 1. It may provide new securityfeatures (e.g. mutual authentication...) as defined by SMG10.

2. It shall be possible to use the USIM as an access module in a GSM network (with a security level

of GSM) for the standardised classes of UMTS mobile termination supporting the GSM BSS andUTRAN radio interfaces. It is not required to support USIM in existing GSM terminals.

3. The UMTS mobile termination shall support phase 1, phase 2 and phase 2+ SIM applications as

access modules. (It shall be up to the UMTS network operator whether or not to accept the use ofthese access modules in its network.)

4. Multiple USIM per smart card and simultaneous activation of several USIMs on one mobile

termination are not required for UMTS phase 1.


6 / 12

5. Multiple user profile per smart card shall be supported as specified in GSM phase 2+ MultipleSubscriber Profile work item.

6. Simultaneous activation of one user profile on different terminals through multiple USIMs is not

required for UMTS phase 1.


7 / 12

Annex 1UMTS Bearer Services

1. Definition of bearer services

Bearer services provide the capability for information transfer between access points and involve onlylow layer functions. These functions are sometimes referred as low layer capabilities (in reference toOSI layers). On the top the application may choose any set of high layer protocols for which theUMTS network does not ascertain compatibility.

2. Bearer service control

The two main categories of bearer services are the connection oriented bearer services andconnectionless bearer services. The bearer service control capabilities depends on the category ofbearer service.

It shall be possible to negotiate the traffic and QoS characteristics of a connection oriented bearerservice during its establishment. It shall be possible to re-negotiate the traffic and QoS characteristicsof a connection oriented bearer service during its lifetime.It shall be possible to add and drop parties to/from a connection oriented bearer service during itslifetime, i.e. to change the communication configuration.It shall be possible for the network to apply connection admission control on a connection orientedbearer service during its establishment. Connection admission control is a network procedure used tolimit admission of new connection oriented bearer services to those which do not compromise thetraffic and QoS characteristics of the already established connection oriented bearer services.It shall be possible for the network to apply flow control on a connection oriented bearer serviceduring its lifetime. Flow control is a network procedure used to regulate the traffic of a user. This isparticularly important for Available Bit Rate and Unspecified Bit Rate traffic types.It shall be possible for the network to apply usage parameter control on a connection oriented bearerservice during its lifetime. Usage parameter control is a network procedure used to check that thetraffic contract negotiated between the user and the network is respected by the user.

Connectionless bearer services lifetime is reduced to the transport of one message.It shall be possible to require traffic and QoS characteristics for a connectionless bearer service.

In order to facilitate the development of new applications, it shall be possible to address applicationsin connections and connectionless messages (notion of port).

It shall be possible for one mobile termination to have more than one bearer service simultaneously(one or more connection oriented bearer services and/or one or more connectionless bearer services).

3. Characterisation of bearer services

Bearer services are characterised from a static point of view by a set of low layer attributes. This sethas been chosen so that a bearer service can be entirely defined by assigning values to the attributes ofthe set. All the attributes and their possible values are listed in this section. Additional attributes maybe specified in latter releases.

The parameters of the set are grouped into two categories;- Information transfer attributes, which characterise the network transfer capabilities required for

transferring user information between two or more access points.


8 / 12

- Information quality attributes, which characterise the quality of the user information transferred betweentwo or more access points.

Giving one of the possible values to each attribute defines a candidate bearer service. However, anycombination is neither meaningful nor necessarily supported by the UMTS system. The meaningfuland supported combinations are specified in the following section.

• • Information transfer attributes

(i) connection mode attribute

• connection oriented• connectionless

(ii) traffic type attribute

• constant bit rateUsed for sources that require a static amount of bandwidth allocation in the network during theconnection lifetime. The source is characterised by the Peak Bit Rate information transfer rateattribute. The source may emit at or below the Peak Bit Rate at any time and for any duration. Thesource keeps the control of the bit rate emission.

• variable bit rateUsed for sources that require a dynamic amount of bandwidth allocation in the network during theconnection lifetime. The source is characterised by the Peak Bit Rate and Minimum Bit Rateinformation transfer rate attributes, and whenever possible by the Mean Bit Rate information transferrate attribute. The source keeps the control of the bit rate emission.

• available bit rateUsed for sources that require a dynamic amount of bandwidth allocation in the network during theconnection lifetime and have the ability to reduce or increase their information rate if the networkrequires them to do so. The source is characterised by the Peak Bit Rate and Minimum Bit Rateinformation transfer rate attributes. The network controls the source rate through flow controlmechanisms. The bandwidth available from the network may vary but shall not become less than theMinimum Bit Rate.

• unspecified bit rateUsed for sources that do not require any specific amount of bandwidth allocation in the networkduring the connection lifetime. The source is not characterised by any information transfer rateattribute. This is a best effort service.

(iii) timing end to end attribute

• required• not required

The value required applies when a timing relationship is required between source and sink(s) ofinformation. End to end timing is necessary for real time information.

(iv) information transfer rate attribute(iv-1) peak bit rate (sub)attribute(iv-2) mean bit rate (sub)attribute(iv-3) minimum bit rate (sub)attribute


9 / 12

The Peak Bit Rate is defined as the maximum bit rate a source transmits data. The Mean Bit Rate isdefined as the average bit rate a source would transmit data if it had an infinite activity. The MinimumBit Rate is defined as the minimum bit rate a source transmits data.The possible values for these three (sub)attributes are not a limited set, but a continuous range ofvalues.

(v) symmetry attribute• unidirectional (together with the direction of transmission)• bi-directional symmetric• bi-directional asymmetric

The value unidirectional applies when the information flow is provided only in one direction. Thevalue bi-directional symmetric applies when the information flow characteristics are the same in thetwo directions. The value bi-directional asymmetric applies when the information flow characteristicsare different in the two directions.

(vi) communication configuration attribute• point to point• point to multipoint - multicast• point to multipoint - broadcast

The value point to point applies when the communication is from a single point to another singlepoint. The value point to multipoint - multicast applies when the communication is from a single pointto a limited number of specified destinations. The value point to multipoint - broadcast applies whenthe communication is from a single point to an unlimited number of unspecified destinations.

(vii) structure attribute• message• flow

The value message applies when the information (the Service Data Units or SDUs) provided by asource shall be delivered with the same structure to the sink(s) (the SDUs borders are unchanged bythe network).

• • Information quality attributes

(i) maximum transfer delay attribute

This is the maximum end to end transfer delay required by a source of information. The possiblevalues for this attribute are not a limited set, but a continuous range of values.

(ii) delay variation attribute

This is the maximum end to end transfer delay variation required by a source of information. Thepossible values for this attribute are not a limited set, but a continuous range of values.

(iii) bit error rate attribute

This is the maximum bit error rate required by a source of information. The possible values for thisattribute are not a limited set, but a continuous range of values.


10 / 12

4. Supported combinations

(i) Attributes not applicable to the connection oriented bearer services

Some of the attributes used to characterise bearer services are not applicable to the connectionoriented traffic. Applicability of the information transfer rate (sub)attributes Peak Bit Rate, Mean BitRate and Minimum Bit Rate depends on the value of the traffic type attribute, as indicated in thedescription of the traffic type attribute.

(ii) Attributes not applicable to the connectionless bearer services

Some of the attributes used to characterise bearer services are not applicable to the connectionlesstraffic. Those are the :

• traffic type• timing end to end• information transfer rate• symmetry• delay variation• error characteristic

Furthermore, the only authorised value of the structure attribute for the connectionless traffic ismessage.

(iii) Supported topologies

The supported combinations between the symmetry and communication configuration attributes arelimited to the following topologies :

• point to point unidirectional• point to point bi-directional symmetric• point to point bi-directional asymmetric• unidirectional point to multipoint - multicast• unidirectional point to multipoint - broadcast

(iv) Asymmetric bearer services

In the case of bi-directional asymmetric (connection oriented) bearer services, the following attributesshall be defined for each direction of the connection :

• traffic type• timing end to end• information transfer rate• structure• maximum transfer delay• delay variation• bit error rate• error characteristic

It shall be possible for the two directions of the bi-directional asymmetric connection to have totallyindependent values for these attributes.


11 / 12

(iv) Mobile termination with more than one bearer service simultaneously

In the case of a mobile termination with more than one bearer service simultaneously, it shall bepossible for each bearer service to have totally independent values for the attributes.

(iv) Supported information transfer rates

The only limiting factor for the supported bit rates of connection oriented and connection less bearerservices shall be the Peak Bit Rate. The minimum targets of Peak Bit Rate to be supported by UMTSare radio environment dependent :

• At least 144 kbits/s in satellite radio environment (Note 1).• At least 144 kbits/s in rural outdoor radio environment.• At least 384 kbits/s in urban/suburban outdoor radio environments.• At least 2048 kbits/s in indoor/low range outdoor radio environment.

NOTE 1 : This may only be achieved in a nomadic operating mode.

(v) Supported information quality

The following table indicates the range of values that shall be supported by UMTS for the informationquality attributes.

Timing end to end Required(Real Time)

Timing end to end Not Required(Non Real Time)

Operatingenvironment

BER/Max Transfer Delay BER/Max Transfer Delay

Max Transfer Delay less than 400 ms

BER 10-3 - 10-7(Note 1)

Max Transfer Delay 1200 ms or more(Note 2)

BER = 10-5 to 10-8

Rural outdoor(Terminalrelative speed toground up to 500km/h) (Note 3)

Max Transfer Delay 20 - 300 ms

BER 10-3 - 10-7(Note 1)


BER = 10-5 to 10-8

Urban/ Suburbanoutdoor(Terminalrelative speed toground up to 120km/h)


BER 10-3 - 10-7(Note 1)


BER = 10-5 to 10-8

Indoor/ Lowrange outdoor(Terminalrelative speed toground up to 10km/h)


BER 10-3 - 10-7(Note 1)


BER = 10-5 to 10-8

NOTE 1; There is likely to be a compromise between BER and delay.NOTE 2; The Max Transfer Delay should be here regarded as the target value for 95% of the data.NOTE 3; The value of 500 km/h as the maximum speed to be supported in the rural outdoor environment

was selected in order to provide service on high speed vehicles (e.g. trains). This is not meantto be the typical value for this environment (250 km/h is more typical).

x Bearer Service Negotiation and Teleservice

x.1 SMG projectUMTS Radio AccessGSM Radio Access

x GSM-UMTS Core NetworkUMTS Services

x.2 Linked work items

x.3 Justification

UMTS TS 22.05 « Services and Service Capabilities » identifies the service capabilities provided by UMTS which allowthe creation of new and innovative applications. These building blocks are the teleservices, the bearer services and theservice features.

Teleservices and bearer services may be requested from any originating point in the network, typically either the mobilestation, a server or an interworking gateway with other networks. For connection oriented bearer services, negotiationshall be possible at bearer set-up and re-negotiation after bearer set-up. In order to ensure backward compatibility withGSM, and support for UMTS services in legacy networks, the negotiation procedure used to set-up/modify these servicesshould also be able to adapt and operate over legacy networks (GSM, fixed network etc). Transport mechanisms shallsupport the teleservices and bearer services in the UMTS core network. API and control protocols are required to set-up/negotiate/re-negotiate the teleservices and bearer services. This is the purpose of this work item.

This work item is a UMTS phase 1 work item.

x.4 Service Aspects

This work item proposes the creation of the API and control protocols which shall be used by network elements (typicallyMobile Station, Server or Gateway) to set-up teleservices, to negotiate at set-up and re-negotiate after set-up bearerservices, as well as the transport mechanisms to support the teleservices and bearer services in the UMTS core network.

For teleservices :

1. speech• selection of speech codec or if not default codec• selection of interworking to PSTN, ISDN, GSM, Internet

2. emergency calls3. short message service4. facsimile5. internet access6. Support interworking with PSTN, N-ISDN, GSM, X.25 and IP networks with their respective numbering schemes.

For bearer services :

1. Support up to 64 kbit/s circuit switched bearer services.2. Support packet switched data services of at least 2 Mbit/s peak bit rate.3. Allow to set-up, re-negotiate and clear connections with a range of traffic and performance characteristics. It shall

be possible to apply traffic policies (e.g. connection admission control, flow control, usage parameter control...) on aconnection during its set-up and lifetime.

4. Support a range of traffic and performance characteristics for the connectionless traffic.5. The range of traffic and performance characteristics that shall be supported for connection oriented and

connectionless traffic shall be in line with GPRS phase 2+ release 99.6. GPRS phase 2+ release 99 point to multipoint communication configurations shall be supported.7. Allow one mobile termination to have more than one connection mode (connection oriented and connectionless

trafic) and/or more than one connection simultaneously. It shall be possible for each connection to have independenttraffic and performance characteristics. It shall be possible for each connectionless message to have independenttraffic and performance characteristics.

8. In order to facilitate the development of new applications, it shall be possible to address applications to/from aUMTS mobile termination in connection oriented and connectionless traffic modes (notion of port).

9. Calls with multiple connections are not supported.10. Support interworking with PSTN, N-ISDN, GSM, X.25 and IP networks with their respective numbering schemes.

x UTRAN Bearer Capabilities

x.1 SMG projectx UMTS Radio Access

GSM Radio AccessGSM-UMTS Core NetworkUMTS Services


x.3 Justification

UMTS TS 22.05 « Services and Service Capabilities » identifies the broadband transport and bearer control capabilitiesof UMTS.

UTRAN is the new access network defined in UMTS for supporting these broadband bearer capabilities in the accesspart of the UMTS network. UTRAN transport and control protocols shall be specified to fulfil UMTS TS 22.05requirements. This is the purpose of this work item.


x.4 Service Aspects

This work item proposes the creation of transport and control protocols in the UTRAN to fulfil the followingrequirements :

1. It shall be possible to connect one UTRAN to one and only one UMTS core network. (In the case of a phase 1 UMTScore network consisting of both a GSM NSS and a GPRS backbone, its shall be possible to connect the UTRAN to thetwo types of infrastructures.)

2. The UTRAN shall support the set-up, re-negotiation and clearing of connections with a range of traffic and

performance characteristics. The re-negotiation may result from an upper layer request or a change in the radioconditions (handover, cell load modification,...) and be mobile station or network initiated. It shall be possible for theUTRAN to apply connection admission control during connection set-up and re-negotiation (Connection admissioncontrol is a network procedure used to limit the admission of new connections to those which do not compromise thetraffic and QoS characteristics of the already established connections). It shall be possible for the UTRAN to applyflow control on a connection during its lifetime (Flow control is a network procedure used to regulate the traffic of auser). It shall be possible for the UTRAN to apply usage parameter control on a connection during its lifetime (Usageparameter control is a network procedure used to check that the traffic contract negotiated between the user and thenetwork is respected by the user).

3. The UTRAN shall support a range of traffic and performance characteristics for the connectionless traffic. 4. The range of traffic and performance characteristics that shall be supported by UTRAN for connection oriented and

connectionless traffic is indicated in TS 22.05 section 5. 5. The UTRAN shall allow one mobile termination to have more than one connection mode (connection oriented and

connectionless traffic) and/or more than one connection simultaneously. It shall be possible for each connection tohave independent traffic and performance characteristics. It shall be possible for each connectionless message tohave independent traffic and performance characteristics.

6. Seamless handover of one mobile termination connection oriented and connectionless traffic between cells of one

UTRAN shall be supported. This shall result in an imperceptible loss of speech (if any) for the user of telephonyservices and data services with no degradation.

7. At least one class of mobile termination supporting both WCDMA and TD-CDMA radio interfaces shall be

standardised. It shall support monitoring of the two types of cells in idle mode (cell reselection procedure) and activemode (handover preparation procedure).

8. For UMTS networks composed of UTRANs with both WCDMA and TD-CDMA radio interfaces, the cell selection and

the paging procedures shall accommodate to the fact that service areas may be either covered by WCDMA cells,WCDMA and TD-CDMA cells or TD-CDMA cells.


6 / 24

9. Handover of one mobile termination connection oriented and connectionless traffic between cells of two UTRANs

using different radio interfaces (i.e. WCDMA and TD-CDMA) and operated by one single UMTS network operatorshall be supported in both directions. SMG1 seeks SMG2 advice on whether it is technically and cost effectivelyfeasible for this type of handover to be seamless.

10. The UTRAN shall facilitate the location of a UMTS mobile termination. It shall be possible for the location precision

to be an UMTS network operator choice, with the precision of the location varying from one part of the service areato another. A minimum precision of around 50 meters shall be achieved in all types of terrestrial radio environments.Location requirements are detailed in TS 22.05 section 8.5.

11. The optimisation of the UTRAN radio interface shall be done around the objectives expressed in TS 22.05 section 5. 12. The USIM requirements defined for later releases of UMTS shall be taken into account in the design of UTRAN (if

having any impact).

x UTRAN and GSM BSS Relationship

x.1 SMG projectx UMTS Radio Access

GSM Radio AccessGSM-UMTS Core NetworkUMTS Services


x.3 Justification

UMTS TS 22.01 « Services Principles » identifies the special nature of the relationship between the UTRAN and GSMBSS access networks. It is expected that UTRAN will start as islands in a sea of GSM BSS. GSM BSS will be a key toservice continuity in UMTS networks. It shall be possible for a network operator operating a UMTS network composedof UTRANs and GSM BSS access networks to manage the mobility (including handover) of dual mode mobile stations.This is the purpose of this work item.


x.4 Service Aspects

This work item proposes the support of resource and mobility management between UTRAN and GSM BSS accessnetworks in line with the following requirements :

1. At least one class of mobile termination supporting the GSM BSS and UTRAN radio interfaces shall be standardised.It shall support monitoring of cells belonging to the two types of access networks in idle mode (cell reselectionprocedure) and active mode (handover preparation procedure).

2. For UMTS networks composed of both GSM BSS and UTRAN access networks, the cell selection and the paging

procedures shall accommodate to the fact that service areas may be either covered by GSM BSS cells, GSM BSS andUTRAN cells or UTRAN cells.

3. For UMTS networks composed of both GSM BSS and UTRAN access networks, the handover procedures in the

UTRAN and the GSM BSS shall support handover between GSM BSS and UTRAN cells of connection oriented andconnectionless traffic, in both directions (i.e. UTRAN to GSM BSS and GSM BSS to UTRAN). Some traffic flows maybe re-negotiated, temporarily liberated or re-established during these handover procedures because of the differentbearer capabilities of the GSM BSS and UTRAN access networks. A detailed list of handover requirements needs tobe defined service per service by SMG1 (i.e. for all GSM phase 2+ release 99 bearer services, teleservices andsupplementary services).

x MAP over TCP/UDP/IP x.1 SMG project UMTS Radio Access GSM Radio Access X GSM-UMTS Core Network UMTS Services x.2 Linked work items None identified x.3 Justification It has been identified that the UMTS core network will evolve from the GSM core network. In particular, the HLR willevolve into a Service Provider controlled database. It is not seriously doubted that the protocol used to communicatebetween an HLR and network subsystem nodes, e.g. the SGSN, will be an evolution of MAP (GSM 09.02). At this point,it is hard to say anything, with any level of certainty, regarding the detail of the functions that will enhance an HLR. Whatcan be said with certainty is that: • the volume of the information to be transferred between an HLR and a network subsystem node will increase

substantially. Already, subscription data volumes exceed that of the SCCP UNITDATA service and inelegantsolutions have been improvised at the MAP level. This ad hoc mechanism should not be continued. The correctsolution is to find a suitable transport mechanism;

• the underlying transport mechanism used by MAP should not assume a homogenous world. Diversity of networking

technology throughout the world, reuse of existing networking investments, must all be recognized and taken intoaccount; and

• the underlying transport mechanism used to deliver MAP PDUs must be much more flexible than the current SS7

stack (TCAP/SCCP/MTP). In cannot be assumed in UMTS that Service Providers will have access to an SS7 entrypoint; in fact, the reverse must be assumed. The physical-level capabilities of SS7 are limited by ISDN’s trunkingstructure; these are much too restrictive for UMTS and should not be built upon.

In the last bullet point, “flexible” means that the underlying transport mechanism used to transfer MAP PDUs shouldsatisfy the following requirements: • connection-oriented/connectionless transport services should be supported; • low to very high bandwidth communications should be possible (from 64kbps to Xmbps); • the transport service should not assume a lower layer architecture-it should be operable over X.25, Frame Relay,

ATM, WAN/LAN and other networking technologies local to different parts of the world. It should separate MAPfrom the underlying network structures;

• the transport service should be deployable within Service Provider premises (who will certainly not all be SS7

trusted partners); and • the transport service should not be reinvented, but should be an “off the shelf” solution which is widely available.

While an exhaustive, i.e. time consuming, academic study could be made of various solutions that meet theserequirements, Motorola believes that this will only delay UMTS and yield little information that is not already widelyknown throughout the industry. The obvious solution seems clear: carry MAP over TCP/UDP/IP.

x.4 Service Aspects

The work item will upgrade MAP’s transport service, allowing new Service Provider’s to easily access the UMTS market.It will also free MAP from the limitations imposed upon it by SS7, giving MAP the ability to expand more freely.

x Service Management x.1 SMG project UMTS Radio Access GSM Radio Access GSM-UMTS Core Network x UMTS Services x.2 Linked work items Virtual Home Environment x.3 Justification UMTS TS 22.01 « Service Principles » has created the concept of the Virtual Home Environment, which is addressed ina separate work item. However, Service Providers will require a set of tools to manage the VHE which are collectivelycovered by the term Service Management. This will involve the creation, deployment, provisioning and removal ofservices on a per-user basis. It will also require the service provider to be able to determine within UMTS servingnetwork if specific services cannot be offered due to lack of supporting features or temporarily unavailability. Oneimportant requirement for the service management is the provision of a consistent service platform which integratesharmoniously the different VHE technologies. A work item is therefore required to address these requirements, and develop a solution for Service Managementcovering these aspects.

x UMTS Access Securityx.1 SMG project UMTS Radio Access GSM Radio Access x GSM-UMTS Core Network UMTS Services


x.3 Justification

UMTS introduces security requirements for access to UMTS networks. Interoperability issues (access to UMTS networkswith GSM access modules and access to GSM networks with UMTS access modules) are also seen as essential. A workitem is required to develop a security model with appropriate signalling interfaces between the components. This work item is a UMTS phase 1 work item. x.4 Service Aspects The USIM requirements for UMTS phase 1 are the following :

1. The UMTS mobile termination shall support phase 1, phase 2 and phase 2+ SIM applications as access modules. (Itshall be up to the UMTS network operator whether or not to accept the use of these access modules in its network.)

2. USIM is the GSM phase 2+ release 99 SIM for UMTS phase 1. It may provide new security features (e.g. mutual

authentication...) as defined by SMG10. 3. It shall be possible to use the USIM as an access module in a GSM network (with a security level of GSM) for the

standardised classes of UMTS mobile termination supporting the GSM BSS and UTRAN radio interfaces. It is notrequired to support USIM in existing GSM terminals.

4. Multiple USIM per smart card and simultaneous activation of several USIMs on one mobile termination are not

required for UMTS phase 1. 5. Multiple user profile per USIM shall be supported as specified in GSM phase 2+ Multiple Subscriber Profile work

X UMTS Services


VHE

x.3 Justification

UMTS is a telecommunications system which allows person to person and machine to machine interactions. Addressingschemes allow users (people or machines) to indicate to the system the target of a particular communications session.Traditionally, this has involved a user dialling a telephone number to indicate the destination of a telephone call. This WI shall elaborate the desirable features of the UMTS advanced schemes requirements for numbering, addressingand Identities for UMTS and translation mechanisms which could be used to enhance the service to the customer. The requirements developed in this WI are to be used within ETSI NA2 to develop a proposal for numbering, addressingand identities applying existing schemes or developing new ones. Other ETSI groups will be involved in the developmentof addressing of applications and network elements.

This work item is a phase 1 work item.

x.4 Service Aspects

In addition to present numbering schemes, connection set up may be based on an alpha-numeric basis, either in place of atraditional number or in the style of the Internet. This may also be extended so as not to exclude other approaches, basedon database checking, and also for terminal as well as user/subscriber numbering. This Work item is applicable to bothGSM and UMTS. The need for UMTS users to be able to interwork with users on legacy schemes. These would encompass telephony, dataand multimedia. Unique identification of various entities in an UMTS environment is required. For UMTS phase 1 the requirements are the following :• The phase 1 UMTS core network shall support interworking with PSTN, N-ISDN, GSM, X.25 and IP networks with

their respective numbering schemes (E.164, X.121, IP v4/6).Different UMTS internal identities (e.g. location areas, cell IDs) have to be consideredx.5 MMI-AspectsNumbering is an MMI topic.x.6 Charging AspectsIs charging still based on the dialled number?x.7 Security AspectsNone identified.

x UMTS Charging and Billing x.1 SMG project UMTS Radio Access GSM Radio Access GSM-UMTS Core Network X UMTS Services x.2 Linked work items None identified x.3 Justification UMTS Charging and Billing requirements cover a range of voice and data services which are not yet available in GSM.Whilst GPRS billing features will cover many aspects of packet data, it does not yet address the QoS aspects required formultimedia and other packet-data oriented services. There is also a requirement for online billing and for external 3rd

parties (Value Added Service Providers) to be able to offer services and receive payment. These requirements arecovered in SMG1 Service Requirement specification 22.15. A work item is therefore required to address these requirements, and develop a solution for UMTS Charging and Billing. This work item is a phase 1 work item. x.4 Service Aspects The UMTS phase 1 requirements are the following : 1. The phase 1 UMTS core network shall support the generation of call data records based on the traffic (volume, bit

rate) and performance provided to the user. 2. The phase 1 UMTS core network shall support on-line billing. Billing of 3rd party value added services with the

concept of one-stop-billing shall be supported by the phase 1 UMTS core network through standardised procedures. x.5 MMI-Aspects None. x.6 Charging Aspects This work item addresses all charging aspects of UMTS. x.7 Security Aspects None. x.8 Impacts

Teleservice and Bearer Service Negotiation.UTRA and GSM BSS relationship.Enhanced QoS support in GPRS.

x.3 Justification

It has been identified that the phase 1 UMTS core network will be an evolution of the GSM core network. Furthermore, itwill be possible to integrate GSM access networks in a UMTS network to guarantee service continuity. It is foreseen thatUMTS will provide a transport platform for diverse application types including real time and interactive applications.The GSM BSS access network and the GPRS backbone provide an infrastructure that can be evolved to meet UMTSrequirements. However, in addition to the bearer service classes supported by the GPRS platform today, it must supportreal time and interactive applications. This is the purpose of this work item.

This work item is a phase 1 work item.

x.4 Service Aspects

The requirements for the GPRS part of the GSM BSS access network are the following :

• The GSM BSS (GPRS part) shall allow to set-up, re-negotiate and clear connections with a range of traffic andperformance characteristics. The re-negotiation may result from an upper layer request or a change in the radioconditions (handover, cell load modification,...). It shall be possible to apply connection admission control duringconnection set-up and re-negotiation. It shall be possible to apply flow control on a connection during its lifetime. Itshall be possible to apply usage parameter control on a connection during its lifetime.

• The GSM BSS (GPRS part) shall allow to request a range of traffic and performance characteristics for theconnectionless traffic.

• The GSM BSS (GPRS part) shall allow one mobile termination to have more than one connection mode (connectionoriented and connectionless trafic) and/or more than one connection simultaneously. It shall be possible for eachconnection to have independent traffic and performance characteristics. It shall be possible for each connectionlessmessage to have independent traffic and performance characteristics.

The requirements for the GPRS backbone are the following :

1. Support packet switched data services of at least 2 Mbit/s peak bit rate. 2. Allow to set-up, re-negotiate and clear connections with a range of traffic and performance characteristics. It shall

be possible to apply traffic policy (e.g. connection admission control, flow control, usage parameter control...) on aconnection during its set-up and lifetime.

3. Support a range of traffic and performance characteristics for the connectionless traffic. 4. Allow one mobile termination to have more than one connection mode (connection oriented and connectionless

trafic) and/or more than one connection simultaneously. It shall be possible for each connection to have independenttraffic and performance characteristics. It shall be possible for each connectionless message to have independenttraffic and performance characteristics.

5. In order to facilitate the development of new applications, it shall be possible to address applications to/from a

mobile termination in connection oriented and connectionless traffic modes (notion of port).

3 UMTS Phase 1 capabilities

Tdoc 037 is the final version of the specification produced by the UMTS Phase 1 Ad Hoc. It is based on anumber of contributions, including Q.1701 and TG.60. This document shall be used by PT SMG to produceversion 1.0.0 of the new specification « UMTS Phase 1 Capabilities ».

This specification introduces a phased approach to UMTS. It was agreed by all the delegates of the Ad Hocthat UMTS Phase 0 is an unclear concept and that it shall not be used. UMTS Phase 1 and the first releaseare targeted for 1999, followed by yearly incremental releases of these specifications. UMTS phase 2 isplanned for release 2002.

This specification lists the capabilities required for UMTS phase 1. In summary, phase 1 consists of a newaccess network (UTRAN) with broadband bearer capabilities and interoperability facilities with the GSM BSS,connected to a core network which is an evolution of the GSM phase 2+ core network. The fundamentaldifference between GSM and UMTS phase 1 resides in the support of high bit rate bearer services with thenotion of negotiated traffic and QoS characteristics.

This specification presents as well a detailed work plan for UMTS phase 1.

It has also been agreed to compare UMTS Phase 1 capabilities with Q.1701 Capability Set table. Missingcapabilities shall be considered for release 2000 onwards.

Note: The issue of small private stand-alone networks using standard UMTS hand-sets to roam to publicUMTS networks in a secure and cost effective manner was raised and needs further consideration.

PENDINGPT SMG shall re-format Tdoc 037 to produce the version 1.0.0 of the specification for SMG#26.PT SMG shall propose a strategy for maintaining the specifications numbering for GSM and UMTSspecifications.
