Broadcast Channels (BCH)Nov 17, 2003Frequency Correction Channel (FCCH)Downlink ChannelBTS: Transmits a carrier frequency (Pure sine wave of 67.7 KHz) This Solve 2 purpose :a> Make sure that this is BCCH Carrierb> To allow the MS to synchronize to the frequency

MS: After Switch on MS Scan for this channel, since it has no information to which frequency to use. FCCH carrier enables a mobile to tune its frequency to that being broadcast by the BTS.

Broadcast Channels (BCH)Nov 17, 2003Syncronization Channel (SCH)Downlink ChannelsBTS: Transmits TDMA Frame number + Base Station Identity Code (BSIC= NCC + BCC )

MS: MS decodes the BSIC if the chosen BTS is GSM Base station within a cell

Broadcast Channels (BCH)Nov 17, 2003Broadcast Control Channel (BCCH)

Downlink Channels

BCCH contains the detailed Network and cell specific information such as :Frequency used by Cell and its Neighboring cells.Frequency HSNPaging GroupsLAIMax output power allowed in the cell

Common Control Channels (CCCH)Nov 17, 2003Paging Channel (PCH)Downlink Channels

BTS: Broadcast the paging message to indicate the Incoming Calls or Incoming SMS. Paging message also includes the MSs identity number IMSI/TMSI

MS: MS listens to the PCH. If it identifies its own mobile subscriber identity number on the PCH, it will respond.

Common Control Channels (CCCH)Nov 17, 2003Random Access Channel (RACH)RACH is transmitted Uplink only

When mobile is paged , it replies on RACH requesting a signaling channel.

RACH can also used if the MS wants to make a contact the NW/ Originating calls

Common Control Channels (CCCH)Nov 17, 2003Access Grant Channel (AGCH)Downlink channelAGCH is answer to the RACH

NW assigns a signaling channel (SDCCH) to the MS. This assignment is performed on the AGCH

Dedicated Control Channels (DCCH)Nov 17, 2003Stand Alone Dedicated Control Channel (SDCCH)SDCCH is bi-directional ChannelSystem SignalingCall SetupAuthenticationLocation UpdateAssignment of Traffic channels and Transmission of Short messages (in idle mode)

Dedicated Control Channels (DCCH)Nov 17, 2003Slow Associated Control Channel (SACCH)SACCH is transmitted in both Uplink and Downlink directionsSACCH is associated with each SDCCH and also with TCHUplink : MS Sends the averaged measurement on its own BTS and neighboring BTSs

Downlink: MS receives information regarding information concerning Transmit power to useInstructions on Timing Advance

Dedicated Control Channels (DCCH)Nov 17, 2003Fast Associated Control Channel (FACCH)While Calls in progress and HO is required FACCH is usedFACCH works in Stealing mode meaning that one 20ms segment of speech is exchanged for signaling information necessary for the HOSend sms in active modeCell Broadcast Channel (CBCH)CBCH is used in Downlink onlyIt is used to carry Short Message Service Cell Broadcast (SMSCB) and uses the same physical channel as the SDCCH

Traffic Channels (TCH)Nov 17, 2003Traffic channels are Bi-directional logical channel that transfer the user speech or data.Full Rate TCH ( TCH/F) : This channel carries information at a gross rate at 13Kbit/s ** Now it is 22.8 Kbit/s with latest R9.1Half Rate TCH (TCH/H) : This Channel carried information at a gross rate at 6.5Kbit/s* * Now it is 11.4 Kbit/s with latest R9.1Enhance Full Rate : The speech coding in EFR is still done at 13Kbit/s, but the coding mechanism is different that is used for normal FR. EFR gives better speech quality at the same bit rate than normal FR.

Nov 17, 2003S. Rajshekhar DeshrajRelationship Between Burst & FrameBurst : Physical content of a TS is called Burst.There are 5 types of Bursts each having 15/26 ms duration and 156.25 Bits.

Hyperframe: In GSM system every TDMA frame is assigned a fixed number, which repeats itself in a time period of 3 HOURS 28 MINUTES 53 SECONDS 760 MILLISECONDS. This time period is referred to as Hyperframe.Superframe : =51x26 Multiframes. So, Duration =51x26x8x15/26=6Sec 120msMultiframe :There are two types of multiframe. 26 TDMA Frame Multiframe :Used to carry TCH, SACCH and FACCH Duration =26 x 8 x 15/26 =120ms51 TDMA Frame Multiframe : Used to carry BCCH,CCCH,SDCCH and SACCH.Duration =51 x 8 x 15/26 =235.38ms

Mapping of Logical ChannelSDCCH+SACCH: Cycle=102 TS This sequence is repeated after last idle frame.The Uplink & Downlink pattern are time shifted, so SDCCH sub channel is sent in frame 0-3 on downlink and in frame 15-18 on uplink. The reason for this is to achieve efficient communication, by giving MS time to calculate its answer to the request received on down link SDCCHNov 17, 2003

Usage of SDCCHThe SDCCH are used in some different ways in the GSM network:

Registrations: Periodic Location Updates, IMSI Attach/Detach Call Setup: Immediate Assignment -> Assignment. SMS point-to-point: SMS messages to/from MS in Idle mode. Fax Setup Optional: USSD (Unstructured Supplementary Service Data) data transfer. MSNetwork. Similar to SMS. Controlled by the MSC.

Nov 17, 2003

Possible ConfigurationsSDCCH/8 : 8 Sub channels for signaling are mapped on 1 TS, this results 1 less TCH for the cell.SDCCH/4 (Combining BCCH and SDCCH) :4 Sub channels for signaling are mapped on BCCH TS. As a result Paging capacity on BCCH is reduced by 1/3.CBCH : If CBCH is active 1 sub channel of SDCCH is replaced by 1 CBCH channel.

Limitations : SDCCH/8 in a cell = Number of TRXsNov 17, 2003

SDCCH CongestionNov 17, 2003SDCCH congestion: All SDCCH in a cell are at the same time busy for a period of time which leads to rejection for new MS.

Reasons : Hanging SDCCH: Are SDCCH that are hanging busy and unusable for a long time (many minutes or indefinite). Hanging SDCCH are generally caused by SW faults.

Heavily used SDCCH: SDCCH seen as continuously busy even though they are used by different MS and thus carries traffic. It may cause due to :> Extreme end-user behaviors: Sport event ending, festivals or celebrations. Increased mean hold time of the SDCCH: Mean hold time increase from 2 to 10 seconds can give SDCCH congestion.

SDCCH Holding TimeNormal Location Updating = 3.5 SecPeriodic Registration= 3.5 SecIMSI Attach = 3.5 SecIMSI Detach = 2.9 Sec (IMSI detach Indication message sent to NW, no authentication is performed (which normally takes 0.6Sec) & no ack is sent to MS.)

Call Setup = 2.7 Sec (MOC) = 2.9 Sec (MTC) Short Message Service(SMS) = 6.2 Sec (Vary depending the length of SMS)

Fax Transmission = 2.7 Sec (MOC) = 2.9 Sec (MTC) False Access = 1.8 Sec (when Channel req is recd by system ,as SDCCH is allocated by sending Imm Ass message, and the system waits a certain time before performing disconnection.)Nov 17, 2003

SDCCH Traffic EstimationsNov 17, 2003Normal Location Update: Mean Holding time =3.5 Sec No of Location update=1.0 per sub and BH

AC: Avg No of Location updates=1000X(1 X 3.5)/3600=0.972 mE/SubIC : No Location updating at all =1000X(0 X 3.5)/3600=0 mE/SubBC: 3 times the Avg no of Location updates=1000X(3 X 3.5)/3600=2.916mE/Sub

SMS: Mean Holding time =6.2 Sec No of SMS submitted =1.0 per Sub and BH

Traffic : 1000 X (1.0 X 6.2) / 3600 =1.7 mE/sub

Call Setup:Mean Holding time =2.7 Sec(MOC) & 2.9 Sec(MTC) Mob Originating Traffic (Incl B Ans)=0.8 BHCA Mob Terminating Traffic (Incl B Ans)=0.4 BHCA

Traffic : 1000 X {(0.8 X 2.7)+(0.4 X 2.9)} / 3600 =0.9 mE/sub

Reasons for SDCCH congestionNov 17, 2003Increased mean hold time of SDCCH can be caused by:

Too low signal strength at access to the systemDue to LSS MS will be lost communication with the system, This will lead to timeout in the BSC (RLINKT ), and thus the SDCCH is used until timeout. Increase ACCMIN.

Congestion of TCH/TRA/RALT Will increase CP execution time before rejecting Imm Ass. Minor increase in mean hold time expected.

C7 problems to MSC (or TRC)In case of C7 signaling problems (SCCP) towards MSC (and/or TRC) can lead to timeout on SCCP connection setup. This will lead to more than 2 minutes hold time for SDCCH.

Handover on SDCCHHandover on SDCCH will in itself increase mean hold time on SDCCH. However minor increase is expected.

Reasons for SDCCH congestionNov 17, 2003 Congestion on Air-interfaceCongestion on Air-interface leads to delay in communication to the MS. Can give timeout in BSC during Imm Ass.Increases SDCCH mean hold time with more than 2 seconds.

Congestion on Abis (LAPD link)Congestion on Abis leads to delay in communication with BTS and MS. Can give timeout in BSC during channel activation (TCHACTIVE). Increase SDCCH mean hold time with more than 5 seconds..

Congestion on A-interfaceCongestion on the A-interface will lead to increased mean hold time on SDCCH. Increase is unknown.

High load in MSC/VLR or HLRHigh load in MSC/VLR and/or HLR will lead to increased mean hold time on SDCCH. Increase is unknown.

How to detect SDCCH congestion in the BSCNov 17, 2003There is no good way to detect SDCCH congestion in real time in the BSC!

A number of symptoms to look for: Increased CP Load. Decreased usage of TRA devices. Location Updates fails => Mobile terminating calls does not reach the subscriber. Subscriber complaints. Can not access the system. STS counters . Object type: CLSDCCH and CLSDCCHO. Seizure Supervision of LCHs (but only for Hanging SDCCHs!)

Preventive actions to avoid SDCCH congestionNov 17, 2003

Avoid combined BCCH in cells with many SDCCHs Use the optional feature Adaptive Configuration of SDCCHs (ACLC) Use USSD (Unstructured Supplementary Service data) with care, can cause long meanhold time on SDCCH. Avoid Handover on SDCCH Proper Dimensioning of the TCHs and TRA devices in the BSC. Use recommended values for Periodic Location UpdatesAvoid unnecessary Periodic Location Updates :BSC: T3212 (RLSBC) = 40 (4 hours) MSC: BTDM (MGIDI) = 240 (4 hours)MSC: GTDM (MGIDI) = 6 (6 minutes) Use Immediate Assignment on TCH. Increases the no of SDCCH in a Cell where SDCCH load is high

SDCCH DimensioningNov 17, 2003SDCCH Dimensioning is a compromise between SDCCH blocking rate and TCH Capacity. In order to have a successful call setup there has to be an available SDCCH as well as available TCH.

Basic SDCCH configuration:

It is recommended to choose1 SDCCH/8 as the basic configuration for all the cells,If LA> 2100 Erlang (500 TRX)

1 SDCCH/4 as the basic configuration for all the cells,If LA< 2100 Erlang (500 TRX)

SDCCH DimensioningNov 17, 2003Automatic SDCCH dimensioning: This can be done with optional Adaptive Configuration of Logical Channel feature.This feature will add extra SDCCH/8 by reconfiguring idle TCH when SDCCH load is high, and revert back to TCH if SDCCH load goes down.

Manual SDCCH Dimensioning :Monitoring SDCCH / TCH Traffic in a cellSDCCH/TCH load ratioSDCCH Grade of Service:- Max allowed TCH GOS % = 2 % The rule of Thumb says: SDCCH/4 : Max. SDCCH GOS =1/2 * 2= 1 % SDCCH/8 : Max. SDCCH GOS =1/4 * 2= 0.5%

SDCCH DimensioningNov 17, 2003Immediate Assignment on TCH:In case of this feature on the channel administration assigns TCH for signaling instead of an SDCCH, based on 7 different channels allocation strategies (CHAPs)

TCH first strategy : Decreases the SDCCH load and enable to use SDCCH/4 in all the cells Traffic load on TCH will in this case increases substantially so this strategy is not recommended.SDCCH first strategy : SDCCH is always allocated first if available, otherwise signaling is performed on TCH.

SDCCH DimensioningNov 17, 2003Example :ASSUME: CELL=3TRX ,SDCCH Traffic =4 Erlang, Bcchtype=NCOMB.No CBCH GOS: SDCCH/4 = 1%, SDCCH/8 =0.5% & TCH % =2%

1> When Immediate Assignment on TCH not used Erlang B Table :To maintain 0.5 % GOS & 4 Erlang min 13 Subchannels reqd 2SDCCH/8 => TCH=(3TRX*8TS) (1BCCH)-(2SDCCH/8)=21TCHs21TCHs with 2 % GOS => 14.04 Erlang

2> When Immediate Assignment on TCH used If we use 1SDCCH/8 only than 4 Erlangs with 8 sub channels GOS=>3 %Congested Erlang will be =4 Erlang x 3 %=0.12Erlang1SDCCH/8 => TCH=(3TRX*8TS) (1BCCH)-(1SDCH/8)=22TCHs22TCHs with 2 % GOS => 14.9 ErlangActual TCH Capacity=14.9 0.12 = 14.7 Erlang

TCH Capacity in the cell is increased with 0.7 Erlang

SDCCH DimensioningNov 17, 2003HALF RATE CAPACITY CALCULATIONHalf rate will affect SDCCH dimensioning since more signaling will be reqd when no of TCH is increased.Important dimensioning factor is therefore the Half rate penetration .i.e.the % of Half rate mobile in a NW.Example: 2 TRX Cell, Half Rate Penetration =10 %, 1 SDCCH/8

TCH/F =14 support 14 SubscriberPenetration 10% of 14 is 1.4 = 2 Subscribers (Reqd 2 Half Rate TCH/H)

Total 13 TCH/F+2TCH/H = 15 TCH requiredCapacity :Erlang B Table: 15 TCH @ 2% GOS => 9.0096 Erlang

SDCCH TrafficTCH TrafficSDCCH/TCH Load Ratio %SDCCH CongestionTCH CongestionSDCCH Mean Holding TimeAvailability of SDCCH ChannelsAvailability of TCH Channels

ParametersNov 17, 2003MFRMS :This parameter defines period of transmission for PAGING REQUEST messages to the same paging subgroup.

T3212 : Is the periodic registration timer

ACCSTATE : Activate/Deactivate the Adaptive config of logical channel feature per cell basis

CHAP :Selecting Channel Allocation profile per cell.

SLEVEL: The attempt to increase the number of SDCCH/8 will take place when allocation of an SDCCH has failed due to congestion.

STIME :Parameter STIME determines how long the system waits before the number of SDCCH/8 added by this function is decreased when the demand for signalling channels has returned to a low level

BTDM :Implicit detach supervision should be equal or longer than T3212 in BSC.

GTDM : is an extra Gurad time in minutes before the subscriber is set to detach.

RLINKT: Radio link time-out This parameter defines the time before an MS disconnects a call due to failure in decoding SACCH messages. The parameter is given as number of SACCH periods (480ms).
