A mobile station configured for “low access priority” (see 3GPP TS 23.060), when attempting to establish a PS connection other than when it is a member of an authorized special access class or in case of a paging response shall, while ignoring MS identities included within PAGING REQUEST messages, start listening to the downlink CCCH until successfully decoding one of the RR messages listed in sub-clause 3.3.1.1.1a. If the RR message indicates an implicit reject for the PS domain (see sub-clause 3.3.1.1.1a) the mobile station shall abort the packet access procedure and initiate the implicit reject procedure (see sub-clause 3.3.1.1.3.2a).
A mobile station configured for "low access priority" attempting a packet access for the purpose of signalling shall set the Low Access Priority Signalling field to "1" in the PACKET RESOURCE REQUEST message (see sub-clause 11.2.16). The Low Access Priority Signalling field shall be set to "0" if the PACKET RESOUCE REQUEST message is sent for any other reason and includes the Low Access Priority Signalling field.

52.8.1.6.1 Conformance requirements
|
In order to uniquely identify the mobile station when sending on uplink, the RLC Header is extended to include the TLLI of the mobile station until contention resolution is completed on the mobile station side.
All the RLC data blocks of an uplink TBF initiated by one phase access shall each contain a TLLI field in the RLC data block header until the contention resolution is completed on the mobile station side. After the reaction time specified in 3GPP TS 05.10 no other RLC data blocks shall contain a TLLI field.
The TLLI_BLOCK_CHANNEL_CODING parameter in the PACKET UPLINK ASSIGNMENT message indicates whether a RLC data block containing a TLLI field in the RLC data block header shall be encoded using CS‑1 or correspondingly MCS-1 in EGPRS TBF mode, or using the channel coding scheme commanded. In standard GPRS TBF mode, the mobile station shall send all other RLC data blocks using the channel coding scheme commanded.
In EGPRS TBF mode, RLC data blocks that are transmitted for the first time shall be transmitted with the MCS commanded, except if the commanded mode is MCS-5-7, in which case the data block shall be transmitted with MCS‑5, or if the commanded mode is MCS-6-9, in which case the data block shall be transmitted with MCS-6.
Upon contention resolution during one phase access, the mobile station shall start transmitting RLC data blocks without the TLLI field no later than the next occurrence of block B((x+3) mod 12) where block B(x) is the radio block containing the contention resolution message.

Test procedure
The MS is triggered to initiate packet uplink transfer of an LLC PDU. The SS assigns packet uplink resources in an IMMEDIATE ASSIGNMENT message indicating one phase packet access. The MS shall start transferring RLC data blocks. The SS reduces the block transfer rate by controlling the USF flag. In this way, the SS forces T3166 (with value 5 s.) to expire before counter N3104 reaches N3104_MAX (with value 45 blocks for current settings). The SS verifies that the MS stops transmitting and re-initiates the packet access procedure.
At the second attempt, the SS sends PACKET UPLINK ASSIGNMENT before T3166 expire. The SS verifies that this time the MS does not abort the access procedure and successfully completes the data transfer.

The contention resolution has failed on the mobile station side when the counter N3104 reaches its maximum value, or timer T3166 expires. The contention resolution also fails, if the mobile station receives a PACKET UPLINK ACK/NACK message or in EGPRS TBF mode a PACKET UPLINK ASSIGNMENT message addressing the TFI associated with the TBF and including a TLLI value other than that the mobile station included in the RLC header of the first RLC data blocks ; in such a case, the mobile station shall not transmit a PACKET CONTROL ACKNOWLEDGEMENT in the uplink radio block specified if a valid RRBP field is received as part of the PACKET UPLINK ACK/NACK message.
In case of a contention resolution failure on the mobile station side, the mobile station shall reset the counter N3104 and stop timer T3166, if not expired. The mobile station shall stop transmitting on the TBF and reinitiate the packet access procedure, unless it has already been repeated 4 times. In that case, a TBF failure has occurred.

Test procedure
The MS is triggered to initiate packet uplink transfer of an LLC PDU. The SS assigns packet uplink resources in an IMMEDIATE ASSIGNMENT message indicating one phase packet access. The MS shall start transferring RLC data block after SS has assigned USF to the MS. The SS acknowledges the RLC block transfer with a PACKET UPLINK ACK/NACK including correct TFI and incorrect TLLI. The SS continue to assign USF to the MS. The SS shall verify that the MS immediately stops transmitting (see note below) and retries packet access procedure.
At the second attempt, the SS sends PACKET UPLINK ASSIGNMENT including a correct TLLI. The SS verifies that this time the MS does not abort the access procedure and successfully completes the data transfer.
NOTE: A mobile station, receiving a commanding message in block number N, shall take an "immediate" action as a result of the command, starting in any block from block number N+1 to N+6 (inclusive).
Maximum duration of the test
5 minutes.

The TLLI is used to uniquely identify the mobile station when sending on uplink. Every RLC data block that is sent on the TBF shall include the TLLI of the mobile station, until the contention resolution is completed on the mobile station side. If MCS-7, MCS-8 or MCS-9 is used for the transmission of the TLLI in EGPRS TBF mode (i.e., the RLC/MAC block is carrying two RLC data blocks), the TLLI shall be inserted in both RLC data blocks. The TLLI shall also be included in the PACKET RESOURCE REQUEST and the ADDITIONAL MS RADIO ACCESS CAPABILITIES messages, if those are sent during the contention resolution.
The retransmission of an RLC data block shall include the TLLI (or the TLLI and the PFI field), if the RLC data block was originally transmitted including these fields, also if the retransmission occurs after the completion of the contention resolution.
The network shall respond by including the TLLI in the PACKET UPLINK ACK/NACK message after the first correctly received RLC data block that comprises the TLLI. In EGPRS TBF mode, the network may instead respond by addressing the mobile station with the TFI of the assigned TBF and including the TLLI (in the CONTENTION_RESOLUTION_TLLI field) in a PACKET UPLINK ASSIGNMENT message, if the resources allocated for the TBF need to be reallocated (see clauses 8.1.1.1.2, 8.1.1.3.1 and 8.1.1.3.2).
The contention resolution is successfully completed on the mobile station side when the mobile station receives a PACKET UPLINK ACK/NACK message addressing the mobile station with the TFI value associated with the uplink TBF and including the same TLLI value that the mobile station has included in the RLC header of the first RLC data blocks, or alternatively, in EGPRS TBF mode, a PACKET UPLINK ASSIGNMENT message addressing the mobile station with the TFI value associated with the uplink TBF and including the same TLLI value that the mobile station included in the RLC header of the first RLC data blocks. The mobile shall then stop timer T3166 and counter N3104.

Test procedure
The MS is triggered to transfer 500 octets of data. In response to EGPRS PACKET CHANNEL REQUEST sent by the MS, the SS assigns packet uplink resources in an IMMEDIATE ASSIGNMENT message indicating one phase packet access.
SS allocate resources to the MS to transfer RLC data blocks. SS verifies that all the data blocks contain TTLI field. SS sends a PACKET UPLINK ASSIGNMENT message addressing the MS with the TFI value associated with the Uplink TBF and including the correct TLLI in the CONTENTION_RESOLUTION_TLLI field. SS reallocate the resources of the uplink TBF in the PACKET UPLINK ASSIGNMENT message by changing the associated TFI and Coding scheme of the uplink TBF.
SS verifies that MS takes into consideration the resource reallocation in the PACKET UPLINK ASSIGNMENT message by checking that the MS uses the new TFI and coding scheme for transmission of new RLC data blocks and that the MS does not include TLLI in the RLC Data Block header.
Maximum duration of the test

|
The mobile station shall monitor the downlink PDCHs corresponding to (i.e. with the same timeslot number as) its assigned uplink PDCHs starting with the lowest numbered PDCH, then the next lowest numbered PDCH, etc., up to the one corresponding to the highest numbered assigned uplink PDCH.
Whenever the mobile station detects an assigned USF value on an assigned PDCH, the mobile station shall transmit either a single RLC/MAC block or a sequence of four RLC/MAC blocks on the same PDCH and all higher numbered assigned PDCHs. The time relation between an uplink block, which the mobile station shall use for transmission, and the occurrence of the USF value is defined in 3GPP TS 45.002. The number of RLC/MAC blocks to transmit on each PDCH is controlled by the USF_GRANULARITY parameter characterising the uplink TBF. The mobile station shall ignore the USF on those higher numbered PDCHs during the block period where the assigned USF value is detected and during the block period(s) in which the mobile station has been granted permission to transmit.

Test Procedure
The MS is triggered to initiate packet uplink transfer data in RLC acknowledged mode. The SS orders the MS to use two-phase access procedure. Up to 4 timeslots are assigned according to the mobile multislot class (TS 5.02 Annex B.1).
1) The SS signals to the MS the assigned USF addressing the MS on the lowest assigned PDTCH. It is checked that the MS sends RLC/MAC data blocks in the next radio block period on all assigned PDTCH and that each data block contains the correct TFI without TLLI.
The SS acknowledges the received data and assigns the USF addressing the MS. The check is repeated.
The same procedure is going on until the MS completes the packet data transfer.
2) The SS signals to the MS the assigned USF addressing the MS on the highest assigned PDTCH. It is checked that the MS sends RLC/MAC data blocks in the next radio block period only on the highest assigned PDTCH and that each data block contains the correct TFI without TLLI.
The SS acknowledges the received data and assigns the USF addressing the MS. The check is repeated.
The same procedure is going on until the MS completes the packet data transfer.
Maximum Duration of Test

Test Procedure
The MS is triggered to initiate packet uplink transfer data in RLC acknowledged mode. The SS orders the MS to use two-phase access procedure. 2 uplink timeslots are assigned.
1) The SS signals the assigned USF addressing the MS on the lowest assigned PDCH. It is checked that the MS sends RLC/MAC data blocks in the next 4 radio block periods on all assigned PDCHs and that each data block contains the correct TFI without TLLI.
2) The SS acknowledges the received data and assigns the USF addressing the MS. It is checked that the MS sends RLC/MAC data blocks in the next 4 radio block periods on all assigned PDCHs, except for the block allocated via the polling mechanism it is checked that the MS sends PACKET CONTROL ACKNOWLEDGEMENT.
3) In the last block period of the above procedure, the SS signals the assigned USF addressing the MS on the lowest assigned PDTCH. It is checked that the MS sends RLC/MAC data blocks in the next 4 radio block periods on all assigned PDCHs and that each data block contains the correct TFI without TLLI.
4) The same procedure is going on until the MS completes the packet data transfer.

Test Procedure
The MS is triggered to initiate a packet uplink data transfer in RLC acknowledged mode and with Extended Dynamic Allocation MAC mode. The SS orders the MS to use two-phase access procedure.
1) At this point in time the MS has an uplink EGPRS TBF established with Extended Dynamic Allocation MAC mode. It may receive RLC/MAC blocks containing RLC/MAC control blocks for the uplink EGPRS TBF on the PDCH carried on the lowest numbered timeslot in the allocation.
To test that the MS decodes and interprets correctly all RLC/MAC blocks containing RLC/MAC control blocks sent by the network on the lowest numbered timeslot in the PDCH allocation when there is no concurrent downlink TBF the SS process as follow:
- The SS sends on the lowest numbered timeslot in the PDCH allocation a PACKET DOWNLINK ASSIGNMENT message to establish a concurrent downlink TBF with the Extended Dynamic Allocation MAC mode. The SS checks that the MS sends in response a PACKET CONTROL ACKNOWLEDGEMENT message on the lowest numbered timeslot in the PDCH allocation.
2) At this point in time the MS has an uplink EGPRS TBF and a downlink EGPRS TBF established with Extended Dynamic Allocation MAC mode. It may receive RLC/MAC blocks containing RLC/MAC control blocks for the uplink EGPRS TBF on the PDCH carried on the lowest numbered timeslot in the uplink PDCH allocation or on any of the common timeslots assigned to the downlink and uplink PDCH allocation.
To test, in case there is a concurrent downlink EGPRS TBF, that the MS decodes and interprets correctly all RLC/MAC blocks containing RLC/MAC control blocks sent by the network on the PDCH carried on the lowest numbered timeslot in the uplink PDCH allocation or on any of the common timeslots assigned to the downlink and uplink PDCH allocation, the SS process as follow:
- The MS is triggered to transfer 64+1 (window size +1) EGPRS RLC data blocks without acknowledgement from SS in such a way that the window is stalled.
- The SS sends on the PDCH carried on the lowest numbered timeslot in the uplink PDCH allocation a PACKET UPLINK ACK/NACK message acknowledging only the oldest EGPRS RLC data block. Then the MS is triggered to transfer one EGPRS RLC data block. If the MS has correctly decoded the PACKET UPLINK ACK/NACK message, the BSN of the EGPRS RLC data block shall be the next in sequence expected BSN.
- The SS sends on one of the common timeslots assigned to the downlink and uplink PDCH allocation a PACKET UPLINK ACK/NACK message acknowledging only the oldest RLC data block. Then the MS is triggered to transfer one EGPRS RLC data block. If the MS has correctly decoded the PACKET UPLINK ACK/NACK message, the BSN of the EGPRS RLC data block shall be the next in sequence expected BSN. The test is repeated with all PDCHs common for both reception and transmission.
3) To test that the MS does not transmit an RLC data block in any uplink radio block allocated via the polling mechanism the SS process as follow:
- The SS sends on one of the common timeslots assigned to the downlink and uplink PDCH allocation a PACKET UPLINK ACK/NACK message containing the TFI value assigned to the uplink TBF and a valid RRBP. On the block period preceding the block period where the polling response to the PACKET UPLINK ACK/NACK message should be received, the SS assigns an USF to the MS on the lowest numbered timeslot of the uplink PDCH allocation. The SS checks that during the block period where the polling response should be received, the MS responds to the polling with a PACKET CONTROL ACKNOWLEDGEMENT message sent on the PDCH where the polling request was sent and sends RLC data blocks on the other PDCHs of the uplink PDCH allocation. The test is repeated with all PDCHs common for both reception and transmission.
Then the data transfer is completed.
The following table gives the number of timeslots allocated for the uplink and downlink TBFs during the test according to the multislot class (see 45.002 annex B.1):

In case of simultaneous uplink and downlink TBFs and extended dynamic allocation, the network may apply polling in downlink RLC data blocks only when sent on a PDCH common for both reception and transmission. A mobile station operating with extended dynamic allocation need to respond to polling in downlink RLC data blocks only when received on a PDCH common for both reception and transmission.

Test Procedure
The MS is triggered to initiate a packet uplink data transfer in RLC acknowledged mode and with Extended Dynamic Allocation MAC mode. The SS orders the MS to use two-phase access procedure. Then a concurrent downlink TBF is established. The PDCH allocation for the downlink and uplink TBFs is chosen to maximise the number of PDCHs common for both reception and transmission.
The SS sends on a PDCH common for both reception and transmission an EGPRS RLC data block with polling and checks that the MS responds with an EGPRS PACKET DOWNLINK ACK/NACK acknowledging the EGPRS RLC data block in the uplink radio block specified by RRBP. The test is repeated on all PDCHs common for both reception and transmission.
The following table gives the number of timeslots allocated for the uplink and downlink TBFs during the test according to the multislot class (see 45.002 annex B.1):

Test Procedure
The EGPRS capable MS is made to transmit uplink RLC data blocks in EGPRS TBF RLC acknowledged mode. The EGPRS Channel Coding Command IE indicates MCS-1 in the Packet Uplink Assignment message.
The SS checks that the BSN in the received RLC data blocks obeys the following rule:
1. BSN is set to the value 0 at the beginning of each TBF in which the mobile station is the transmitter;
2. BSN is incremented by 1 in each subsequent RLC data block in the TBF;
3. BSN takes on all values in the range 0 to 2047 and then back to 0.
Maximum Duration of Test
30 minutes.

Test Procedure
The EGPRS capable MS is made to transmit uplink RLC data blocks in EGPRS TBF RLC acknowledged mode. The EGPRS Windows Size IE in the Packet Uplink Assignment message indicates the value in accordance with the number of timeslots allocated.
The MS transmits WS (window size) blocks without acknowledgement from the SS. The SS then acknowledges the first N blocks and verifies that the MS shall transmit N more RLC data blocks.
The test procedure is performed for the values of N = 10, 15 and 20.
Maximum Duration of Test
30 minutes.
