51.1 RR / Paging

3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS

The paging procedure is used by the network to cause the MS to establish either an RR connection for circuit switched services or a downlink TBF for EGPRS packet transfer. Normally the MS listens to its paging sub-channel when DRX is used, but this can be modified by the use of different page mode. The correct monitoring of its paging sub-channel on CCCH in different control channel configurations and correct implementation of the paging procedure in the MS are essential. They are the test objectives of this clause.

NOTE:

A R99 MS may optionally use either a Channel Request message or an EGPRS Packet Channel Request to answer to Packet Paging by the SS on CCCH.

In case the MS uses a Channel Request to respond to a Paging Request message on CCCH, the SS shall include GPRS specific message contents in the corresponding Immediate Assignment / Immediate Assignment Reject message.

In case the MS uses EGPRS Channel Request to respond to a Paging Request message on CCCH, the SS shall include EGPRS specific message contents in the corresponding Immediate Assignment / Immediate Assignment Reject message.

51.1.5.1.1 RR / Paging / on CCCH for EGPRS service / normal paging with P-TMSI successful

51.1.5.1.1.1 Conformance requirements

1. The network initiates the paging procedure by sending a paging request message on an appropriate paging sub-channel on CCCH. Paging initiation using a paging sub-channel on CCCH is used when sending paging information to a mobile station and PCCCH is not present in the cell.

2. The mobile station in packet idle mode is required to receive and analyse the paging messages and immediate assignment messages sent on the paging sub-channels on CCCH corresponding to the paging groups determined for it in packet idle mode.

3. A PAGING REQUEST message may include more than one mobile station identification.

4. In a PAGING REQUEST message used for the packet paging procedure, the mobile station shall be identified by the P-TMSI (GPRS TMSI) or its IMSI. If the mobile station is identified by the P-TMSI, it shall indicate the receipt of a paging request to the MM sub-layer.

If the mobile station identified by its IMSI, it shall parse the message for a corresponding Packet Page Indication field:

– if the Packet Page Indication field indicates a paging procedure for RR connection establishment, or the field is not present in the message, the mobile station shall initiate the immediate assignment procedure;

– if the Packet Page Indication field indicates a packet paging procedure, the mobile station shall indicate the receipt of a paging request to the MM sub-layer.

5. The mobile station initiates the packet access procedure by scheduling the sending of CHANNEL REQUEST messages on RACH.

Test Procedure

The test is repeated three times. Each time the MS is paged for the packet paging procedure through a different paging request type message. After receiving a CHANNEL REQUEST with the establishment cause ‘one phase access’, or an EGPRS PACKET CHANNEL REQUEST with the establishment cause ‘signalling’ an open-end TBF is assigned. A USF is assigned to the MS to enable it to transfer an uplink RLC data block. The received data block is acknowledged by the SS with , Final Ack Indicator = ‘1’ , a valid RRBP. The MS sends PACKET CONTROL ACKNOWLEDGEMENT.

Maximum Duration of Test

5 minutes.

NOTE:

EGPRS PACKET CHANNEL REQUEST shall be used to respond to Paging Request for TBF Establishment in the following cases

a. If Release of EGPRS supported is Release 4 or above.

b. If Support of EGPRS Packet Access enhancement is True for a R99 MS.

CHANNEL REQUEST shall be used to respond to Paging Request for TBF Establishment if support of EGPRS Packet Access enhancement is False for a R99 MS.

51.1.5.1.3 RR / Paging / on CCCH for EGPRS service / normal paging with P-TMSI ignored

The MS shall ignore paging not addressing to it. If paging is not implemented correctly unnecessary accesses will be provoked on CCCH which is shared by all MS in a same cell. This kind of the wrong paging behaviour of the same type of MS in a GSM network can block the use of CCCH and will, therefore, cause an unacceptable degradation of the both GSM EGPRS and circuit-switched services to other users of the mobile stations.

51.1.5.1.3.1 Conformance requirements

Paging initiation using the paging subchannel on CCCH is used when sending paging information to a mobile station in idle mode. It is also used when sending paging information to a mobile station in packet idle mode, if PCCCH is not present in the cell.

In a PAGING REQUEST message used for the packet paging procedure, the mobile station shall be identified by the P‑TMSI (GPRS TMSI) or its IMSI. If the mobile station is identified by the P-TMSI, it shall proceed as specified in 3GPP TS 04.18, subclause 3.5.1.2.

51.1.5.2.1.1 Conformance requirements

The paging and immediate assignment type messages contain a page mode information element. This information element controls possible additional requirements on mobile stations belonging to the paging subgroup corresponding to the paging subchannel the message was sent on. This implies that a given mobile station shall take into account the page mode information element of any message sent on its own paging subchannel whatever the nature of this message (paging messages or immediate assignment messages). This further implies that the mobile station does not take into account page mode information element of messages sent on paging subchannels other than its own paging subchannel. The requirements yielded by the page mode information element are as follows:

b) extended paging: the mobile station is required in addition to receive and analyse the next but one message on the PCH.

51.1.5.3 RR / Paging / on CCCH for EGPRS service / paging reorganisation

51.1.5.3.1 Conformance requirements

The paging and immediate assignment type messages contain a page mode information element. This information element controls possible additional requirements on mobile stations belonging to the paging subgroup corresponding to the paging subchannel the message was sent on. This implies that a given mobile station shall take into account the page mode information element of any message sent on its own paging subchannel whatever the nature of this message (paging messages or immediate assignment messages). This further implies that the mobile station does not take into account page mode information element of messages sent on paging subchannels other than its own paging subchannel. The requirements yielded by the page mode information element are as follows:

c) paging reorganization: The mobile station shall receive all messages on the CCCH regardless of the BS‑AG‑BLKS-RES setting. It is required to receive all BCCH messages. When the mobile station receives the next message to its (possibly new) paging subgroup the subsequent action is defined in the page mode information element in that message.

1. To verify that the MS, after reception of a message with page mode set to "paging reorganisation", answers to paging messages (with page mode set to "normal paging") sent on its old CCCH in paging blocks which do not belong to the MS’s paging sub-channel.

2. To test that the MS correctly determines its new paging sub-channel when the number of reserved blocks, BS_AG_BLKS_RES, and the number of 51-multiframes between transmissions of paging messages for mobile stations of the same paging group BS_PA_MFRMS are changed.

3. To test that the MS correctly determines its new paging sub-channel when the number of basic physical channels for CCCH is changed.

51.1.5.3.3 Method of test

Initial Conditions

System Simulator:

1 cell, EGPRS supported, PCCCH absent, Max-Retrans = 2, CCCH_CONF = 0 (1 basic physical channel used for CCCH with non-combined SDCCH), BS_AG_BLKS_RES = 3, BS_PA_MFRMS = 6. SPGC_CCCH_SUP = 0 (SPLIT_PG_CYCLE is not supported on CCCH in the cell).

Mobile Station:

The MS is GPRS attached with a TMSI (only for MS operation mode A or MS operation mode B) and a P-TMSI allocated and SPLIT PG CYCLE negotiated. The mobile station is in packet idle mode and has left the Transfer non-DRX mode period, i.e. the system simulator shall wait for a period equivalent to the value of the NON_DRX_TIMER parameter before sending the first paging message to the MS.

Specific PICS Statements

– Release of EGPRS Supported (TSPC_MS_EGPRS_RELEASE)

– Support of EGPRS Packet Access Enhancement (TSPC_EGPRS_ENHANC)

– MS operation mode A Yes/No (TSPC_operation_mode_A)

– MS operation mode B Yes/No (TSPC_operation_mode_B)

PIXIT Statements

Test Procedure

The page mode is set to paging reorganisation. The MS is paged for packet paging procedure through PAGING REQUEST TYPE 1 which is sent before the MS’s original paging sub-channel re-occurs, but later than the next paging block of that CCCH. The MS starts the random access. The access attempt is rejected.

The SS changes the CCCH configuration with BS_AG_BLKS_RES=2 and BS_PA_MFRMS=5 and waits two SI13 repeat periods, and then sets the page mode to Normal Paging. The MS is paged for packet paging procedure through PAGING REQUEST TYPE 2 sent on the new paging sub-channel. The MS starts the random access. The access attempt is rejected via IMMEDIATE ASSIGNMENT REJECT. PAGING REQUEST TYPE 1 with paging fill frame and page mode set to "paging reorganisation" is sent.

Two additional CCCHs are activated by the SS. The same test procedure as above is repeated.

Maximum Duration of Test

5 minutes.

NOTE:

EGPRS PACKET CHANNEL REQUEST shall be used to respond to Paging and Packet Paging Request for TBF Establishment in the following cases

a. If Release of EGPRS supported is Release 4 or above.

b. If Support of EGPRS Packet Access enhancement is True for a R99 MS.

CHANNEL REQUEST shall be used to respond to Paging Request for TBF Establishment if support of EGPRS Packet Access enhancement is False for a R99 MS.
