Test procedure

The MS is triggered to transfer data, it shall attempt a Two Phase packet access (3GPP TS 04.18 / 3.5.2.1.2). The SS does not answer to the access bursts but stores N (= 80) Random References and verifies that the MS uses all possible values (0 … 7) in its Random Reference.

Justification

The length of the Random Reference is 3 bits two phase packet access (3GPP TS 04.18 / table 9.9). This test verifies that the MS uses all values (0 … 7) in its Random Reference.

The probability that in a sequence of N samples one of the possible value does not appear is 8*(7/8)**N for large N.

Note: The number of samples N has been computed such that the probability of refusing a correct MS is less than 0,02 %.

Initial conditions

System Simulator: default settings except:

Parameter MAX_RETRANS is set to 4 retransmissions.

T3302 = 1 minute

Mobile Station:

Note: MS may be brought into the required condition by causing it to be triggered to perform GPRS attach and the SS responding with ATTACH REJECT in which T3302 is set to 1 minute and the cause set to "MSC temporarily not reachable". MS treats this as a temporary failure and enters the test sequence by restarting the attach procedure.

Specific PICS Statements

PIXIT Statements

Test procedure

The MS shall attempt either a one phase packet access using Channel Request or Access Type signalling using Egprs Packet Channel Request. The SS does not answer to the access bursts but stores N (N=80 in case of Channel Request and N=380 in case of Egprs Packet Channel Request) Random References and verifies that the MS uses all possible values in its Random Reference.

Possible values in case of Channel Request are 0…3 and not using value ‘111’ as a value of the 3 least significant bits for channel request octet (see 3GPP TS 04.18/Table 9.1.8.1)

Possible values in case of Egprs Packet Channel Request are 0…31 (see 3GPP TS 04.60 / 11.2.5a and 3GPP TS 04.18/Table 9.1.8.1).

Justification

In case of Channel Request:

Possible values for Random Reference for one phase packet access are 0 to 3 (value ‘111’ is not allowed). This test verifies that the MS uses all values (0 … 3) in its Random Reference.

In case of Egprs Packet Channel Request

Possible values for Random Reference for signalling are 0 to 31. This test verifies that the MS uses all values (0 … 31) in its Random Reference.

Specific PICS Statements

PIXIT Statements

Test procedure

The MS is triggered to initiate uplink data transfer. The SS waits until the MS sends all M+1 EGPRS PACKET CHANNEL REQUEST messages, and then sends an IMMEDIATE ASSIGNMENT before minimum value of T3146 seconds elapse. In this case the MS shall correctly send the LLC PDU on the assigned PDCH.

The MS is triggered again to initiate uplink data transfer, the SS waits until the MS sends all M+1 EGPRS PACKET CHANNEL REQUEST messages, where M is the parameter Max Retrans broadcast on BCCH. The SS waits until the maximum value of T3146 seconds elapse and sends an IMMEDIATE ASSIGNMENT which shall be ignored by the MS since the access procedure should be aborted.

Note:

Timer T3146 (3GPP TS 04.18 clause 11) depends on parameter TX_INTEGER broadcast on BCCH.

The minimum value of the timer is 2*S+TX_INTEGER slots, where S is given in 3GPP TS 04.08 / 3GPP TS 44.018, Table 3.1.

The maximum value of this timer is 5 seconds. (Subclause 11.1.1 in 04.08)

51.2.2.7 Initiation of the packet access procedure by IPA capable MS / IMMEDIATE PACKET ASSIGNMENT message configured initially and later not configured on MS own Paging sub-channel

51.2.2.7.1 Conformance requirements

If the mobile station supports the IMMEDIATE PACKET ASSIGNMENT message, the mobile station shall monitor cell’s capability for IMMEDIATE PACKET ASSIGNMENT message within paging messages received on its own paging sub-channel.

Purpose of the packet access procedure

EGPRS PACKET CHANNEL REQUEST supported in the cell

EGPRS PACKET CHANNEL REQUEST not supported in the cell

User data transfer – requested RLC mode = unacknowledged

EGPRS PACKET CHANNEL REQUEST with access type = ‘Two Phase Access Request’

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

User data transfer – requested RLC mode = acknowledged

EGPRS PACKET CHANNEL REQUEST with access type = ‘One Phase Access Request’ or ‘Two Phase Access Request’

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

User data transfer – requested RLC mode = acknowledged (Reduced Latency supported by MS)

EGPRS PACKET CHANNEL REQUEST with access type = ‘One Phase Access Request by Reduced Latency MS’ (NOTE 2)

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

User data transfer – requested RLC mode = acknowledged by an IPA capable mobile station

EGPRS PACKET CHANNEL REQUEST with access type = ‘One Phase Access Request’ or ‘Two Phase Access Request by IPA capable MS’ (NOTE 3)

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

Upper layer signalling transfer (e.g. page response, cell update, MM signalling, etc)

EGPRS PACKET CHANNEL REQUEST with access type = ‘Signalling’

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

Upper layer signalling transfer for a mobile station configured for “NAS signalling low priority” (e.g. page response, cell update, MM signalling, etc)

EGPRS PACKET CHANNEL REQUEST with access type = ‘Signalling’ (NOTE 5) or ‘Two Phase Access Request’ (NOTE 6)

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

Upper layer signalling transfer (e.g. page response, cell update, MM signalling, etc) by an IPA capable mobile station

Sending of a PACKET PAUSE message

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ (NOTE 1)

Sending of an MBMS Service Request message

CHANNEL REQUEST with establishment cause = ‘Single block MBMS access’

NOTE 1: Upon sending the first CHANNEL REQUEST message the mobile station shall start timer T3204. If timer T3204 expires before an IMMEDIATE ASSIGNMENT message granting a single block period on an assigned packet uplink resource is received, the packet access procedure is aborted. If the mobile station receives an IMMEDIATE ASSIGNMENT message during the packet access procedure indicating a packet downlink assignment procedure, the mobile station shall ignore the message.

NOTE 2: The One phase Access Request by Reduced Latency MS shall be used by the mobile station supporting reduced latency if Reduced Latency Access is supported by the network. The ‘One Phase Access Request by Reduced Latency MS’ or ‘Two Phase Access Request by IPA capable MS’ may be used instead if the mobile station is capable of both Reduced Latency and IMMEDIATE PACKET ASSIGNMENT and the network supports IMMEDIATE PACKET ASSIGNMENT message and Reduced Latency Access.

NOTE 3: (This note does not apply if Note 2 is applicable) The ‘One Phase Access Request’ with IPA capability signalled by the MultislotClass field in the EGPRS PACKET CHANNEL REQUEST message or ‘Two Phase Access Request by IPA capable MS’ shall be used by the mobile station supporting IMMEDIATE PACKET ASSIGNMENT message if support of the IMMEDIATE PACKET ASSIGNMENT message is signalled by the network.

NOTE 4: The ‘Signalling Request by IPA capable MS’ shall be used if both mobile station and network supports IMMEDIATE PACKET ASSIGNMENT.

NOTE 5: The access type ‘Signalling’ shall be used if a mobile station receives an indication from the upper layers to override NAS signalling low priority

NOTE 6: The access type ‘Two Phase Access Request’ shall be used if a mobile station does not receive an indication from the upper layers to override NAS signalling low priority

51.2.2.7.2 Test purpose

To verify that the IPA capable MS shall monitor cell’s capability for IMMEDIATE PACKET ASSIGNMENT message within the paging messages received on its own paging sub-channel. If the capability for IMMEDIATE PACKET ASSIGNMENT message within the paging messages received on its own paging sub-channel is configured initially by the network, the IPA capable MS follows the packet access procedure defined for an IPA capable MS. Later, when the capability for IMMEDIATE PACKET ASSIGNMENT message is not configured on the IPA capable MS own paging sub-channel via the PAGING REQUEST TYPE 1 with the IPA Support bit set to ‘0’, the MS follows the legacy packet access procedure.

51.2.2.8 Initiation of the packet access procedure by IPA capable MS / IMMEDIATE PACKET ASSIGNMENT message not configured initially and later configured on MS own Paging sub-channel

51.2.2.8.1 Conformance requirements

If the mobile station supports the IMMEDIATE PACKET ASSIGNMENT message, the mobile station shall monitor cell’s capability for IMMEDIATE PACKET ASSIGNMENT message within paging messages received on its own paging sub-channel.

Purpose of the packet access procedure

EGPRS PACKET CHANNEL REQUEST supported in the cell

EGPRS PACKET CHANNEL REQUEST not supported in the cell

User data transfer – requested RLC mode = unacknowledged

EGPRS PACKET CHANNEL REQUEST with access type = ‘Two Phase Access Request’

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

User data transfer – requested RLC mode = acknowledged

EGPRS PACKET CHANNEL REQUEST with access type = ‘One Phase Access Request’ or ‘Two Phase Access Request’

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

User data transfer – requested RLC mode = acknowledged (Reduced Latency supported by MS)

EGPRS PACKET CHANNEL REQUEST with access type = ‘One Phase Access Request by Reduced Latency MS’ (NOTE 2)

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

User data transfer – requested RLC mode = acknowledged by an IPA capable mobile station

EGPRS PACKET CHANNEL REQUEST with access type = ‘One Phase Access Request’ or ‘Two Phase Access Request by IPA capable MS’ (NOTE 3)

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

Upper layer signalling transfer (e.g. page response, cell update, MM signalling, etc)

EGPRS PACKET CHANNEL REQUEST with access type = ‘Signalling’

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

Upper layer signalling transfer for a mobile station configured for “NAS signalling low priority” (e.g. page response, cell update, MM signalling, etc)

EGPRS PACKET CHANNEL REQUEST with access type = ‘Signalling’ (NOTE 5) or ‘Two Phase Access Request’ (NOTE 6)

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

Upper layer signalling transfer (e.g. page response, cell update, MM signalling, etc) by an IPA capable mobile station

EGPRS PACKET CHANNEL REQUEST with access type = ‘Signalling Request by IPA capable MS'(NOTE 4)

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ for initiation of a two-phase access

Sending of a measurement report or of a PACKET CELL CHANGE FAILURE

CHANNEL REQUEST with establishment cause = ‘Single block packet access’

Sending of a PACKET PAUSE message

CHANNEL REQUEST with establishment cause = ‘Single block packet access’ (NOTE 1)

Sending of an MBMS Service Request message

CHANNEL REQUEST with establishment cause = ‘Single block MBMS access’

NOTE 1: Upon sending the first CHANNEL REQUEST message the mobile station shall start timer T3204. If timer T3204 expires before an IMMEDIATE ASSIGNMENT message granting a single block period on an assigned packet uplink resource is received, the packet access procedure is aborted. If the mobile station receives an IMMEDIATE ASSIGNMENT message during the packet access procedure indicating a packet downlink assignment procedure, the mobile station shall ignore the message.

NOTE 2: The One phase Access Request by Reduced Latency MS shall be used by the mobile station supporting reduced latency if Reduced Latency Access is supported by the network. The ‘One Phase Access Request by Reduced Latency MS’ or ‘Two Phase Access Request by IPA capable MS’ may be used instead if the mobile station is capable of both Reduced Latency and IMMEDIATE PACKET ASSIGNMENT and the network supports IMMEDIATE PACKET ASSIGNMENT message and Reduced Latency Access.

NOTE 3: (This note does not apply if Note 2 is applicable) The ‘One Phase Access Request’ with IPA capability signalled by the MultislotClass field in the EGPRS PACKET CHANNEL REQUEST message or ‘Two Phase Access Request by IPA capable MS’ shall be used by the mobile station supporting IMMEDIATE PACKET ASSIGNMENT message if support of the IMMEDIATE PACKET ASSIGNMENT message is signalled by the network.

NOTE 4: The ‘Signalling Request by IPA capable MS’ shall be used if both mobile station and network supports IMMEDIATE PACKET ASSIGNMENT.

NOTE 5: The access type ‘Signalling’ shall be used if a mobile station receives an indication from the upper layers to override NAS signalling low priority

NOTE 6: The access type ‘Two Phase Access Request’ shall be used if a mobile station does not receive an indication from the upper layers to override NAS signalling low priority

51.2.2.8.2 Test purpose

To verify that the IPA capable MS shall monitor cell’s capability for IMMEDIATE PACKET ASSIGNMENT message within the paging messages received on its own paging sub-channel. If the capability for IMMEDIATE PACKET ASSIGNMENT message within the paging messages received on its own paging sub-channel is not configured initially by the network, the IPA capable MS follows the legacy packet access procedure. Later, when the capability for IMMEDIATE PACKET ASSIGNMENT message is configured on the IPA capable MS own paging sub-channel via the PAGING REQUEST TYPE 1 message with the IPA Support bit set to ‘1’, the MS follows the packet access procedure defined for a IPA capable MS.

51.2.3 Packet immediate assignment / One phase packet access

51.2.3.1 Two-message assignment / Successful case

51.2.3.1.1 Conformance requirements

If the mobile station receives an IMMEDIATE ASSIGNMENT message and the Dedicated mode or TBF information element indicates that this is the first message in a two-message assignment, the mobile station shall continue to listen to the full CCCH. The network may send a second IMMEDIATE ASSIGNMENT message within two multiframe periods following the first IMMEDIATE ASSIGNMENT, specifying the packet channel description and, if required, a mobile allocation for the assignment.

On receipt of an IMMEDIATE ASSIGNMENT message or, in case of a two-message assignment, a matching pair of IMMEDIATE ASSIGNMENT messages corresponding to one of its 3 last EGPRS PACKET CHANNEL REQUEST messages, the mobile station stops T3146 (if running), stops sending EGPRS PACKET CHANNEL REQUEST messages, and switches to the assigned PDCH.

Reference

51.2.3.2 Two-message assignment / Failure cases

51.2.3.2.1 Conformance requirements

If the indirect encoding is used, the IMMEDIATE ASSIGNMENT message may contain a CHANGE_MARK_1 field. If that is present, the mobile station shall verify the validity of the SI13_CHANGE_MARK associated with the GPRS mobile allocation to which the message refers, see 3GPP TS 04.60. If the CHANGE_MARK_1 field and the SI13_CHANGE_MARK do not match, the message does not satisfactorily define a PDCH.

The two IMMEDIATE ASSIGNMENT messages in a two-message assignment shall have the same contents of the Request Reference information elements.

If the mobile station does not receive the second IMMEDIATE ASSIGNMENT messages in a two-message assignment within two multiframe periods following the first message, the mobile station shall discard the first IMMEDIATE ASSIGNMENT message received.

If the information available in the mobile station, after the reception of an IMMEDIATE ASSIGNMENT message or the second IMMEDIATE ASSIGNMENT message of a two-message assignment, does not satisfactorily define a PDCH, a TBF establishment failure has occurred.

Reference

3GPP TS 04.18 subclauses 3.5.2.1.3.1 and 3.5.2.1.5.

51.2.3.2.2 Test purpose
