Some important QoSTraffic Class：conversational, streaming,interactive,and background.Maximum Bit Rate（MBR）：The Maximum bitrate is the upper limit a user or

application can accept or provide. Guaranteed Bit Rate (GBR)：Describes the bitrate the UMTS bearer service shall

guarantee to the user or application. Traffic Handling Priority：Within the interactive class, there is a definite need to

differentiate between bearer qualities. This is handled by using the traffic handling priority attribute, to allow UMTS to schedule traffic accordingly.

Allocation/Retention Priority：Priority is used for differentiating between bearers when performing allocation and retention of a bearer.

QoS Mapping

Basic Priority (BP) MappingBP is mapped from the Traffic Class, ARP Seg, THP Seg of I services. It is divided into 16 levels (0 - 15, with the 15 the highest level, 0 the lowest) When the RNC receives the ARP and THP assigned by the core network, it maps the BP based on the Traffic Class, ARP, and THP.Because the value range (15) of The ARP and THP 、 the classes of Traffic Class is far beyond the value range (15) of BP, the values of the ARP and THP are segmented. BP is used for Admission Control and HSPA Scheduling

Scheduling Priority MappingSP (SchPrio) is mapped from the BasicPrio and BearerType. It can be divided into 16 levels (0 -15, with the 15 the highest level, 0 the lowest). Compared with BP, the SP takes one more factor – bearer type - into consideration to differentiate the priorities of different bearer types. The SP is used to schedule the call queue and to select the subscriber to be released in forced release.

Application Priority (AP) Mapping

The AP is mapped from the BPSeg, BearerType, and RateSeg, including 16 levels (0 - 15, with the 15 the highest level, 0 the lowest).The AP involves two application scenarios:

Congestion control priority, which is used to select a subscriber for rate decrease and schedule the DRBC queue in the congestion control process. Load control priority, which is used for reducing load when the system is overloaded

QoS Differentiation of Admission ControlDifferent admission thresholds can be set in admission control based on BP and

different transmission channels.Operator can determine the degree of difficulty to be admitted for users/services

with different ARPs by setting different admission thresholds for different priorities. For example, when the load is heavy, Operator can admit users with higher priority and refuse those with lower priorities, so as to avoid impact on service quality of higher-priority users caused by lower-priority user admission.

QoS Differentiation of Congestion Control

In the event of system congestion, resource preemption can be triggered to

reflect superiority of subscribers with higher priorities and improve call

successful ratio. Its main policies consist of two aspects as follows:

Forced release: The services capable of preemption with higher priorities

are allowed to release forcibly those services with lower priorities. That is, the

subscribers with higher priorities can implement fast access by preempting

the resources of those subscribers who are of lower priorities and subjected

to forced release. This is to reflect differentiation of services between

subscribers.

Downgrade: This policy is used to improve call successful ratio by

decreasing the data bit rate of online subscribers.

QoS Differentiation of Congestion Control-Forced release

7YYUE413N.YUE35YYUE22YN.UE1SchPrioPVIPCIUsers

There are three users in the network: UE1, UE2, and UE3. Now UE4 wants to be

admitted to the network. However, the network is now congested.

Forced release: selection of users to be released forcibly and priority judgment

between users originated forced release and users to be released forcibly are

based on the SP.

15

QoS Differentiation of Congestion Control- Rate Decrease

There are three online users: UE1, UE2, and UE3. Suppose that a new user UE4 requires access to the network, which is now congested due to insufficient downlink power resources in the cell.

1364-UE4732128UE3532128UE22168UE1AppPriDlNormBitRate (kbit/s)Real-time Rate (kbit/s)Users

Rate Decrease : selection of users whose rate is to be decreased in the rate decrease is based

on comparison between APs. And AP reflects ARP. Therefore, ARP differentiation is

reflected in the preceding strategy.

16

QoS Differentiation of Congestion Control- Admission Scheduling

Assume that three new call requests are congested.

Rate Decrease : For a user with preemption capability but failed to release forcibly

or without preemption capability but with queuing capability, when his service

admission is rejected, the system can place the user/service in a queue waiting for

resources for re-access.

QoS Differentiation of Load Control

Suppose that the cell is overloaded. There are two online users: UE1 and UE2.

Load control have the following means of load reduction: data rate decrease of

PS/AMR service, forced handover, forced I/B service handover to the

CELL_FACH, forced call drop, etc.

Summary of Scenarios Applied for BP\SP\AP

When downgrading is performed because of resource congestion, RNC will select users to perform downgrading based on AP. When overload happens, RNC will select users to decrease load based on AP.

Congestion ControlOverLoad Control

Application Priority(AP)

(1) When forced release is performed because of resource congestion, RNC will select users to perform forced release based on SP. (2) When queueing and service admission again are performed because of resource congestion, RNC will select users to perform admission based on SP.

Congestion ControlSP of RNC(SP)

(1) When RAB is admitted, RNC obtains admission threshold based on BP. (2) For HSDPA, when resources for HSDPA are shared by multiple users, RAN (Node B) will allocate the code and power resources to different HSDPA mobiles according to SPI which is equal to BP. (3) For HSUPA, when resources for HSUPA are shared by multiple users, RAN (Node B) will allocate the grant to different HSUPA mobiles according to SPI which is equal to BP.
