The tests are based on TS 24.008.

In this clause, when the expected sequence require that "a mobile originated CM connection is attempted", it shall be for a service other than emergency call.

In this clause, an initial CM message is either a SETUP message, a REGISTER message or a CP-DATA message (in that case the acknowledged mode of operation on SAPI 3 will be established and this message will be sent on SAPI 3).

All tests in this clause shall only be performed in Network Mode of Operation II, unless specifically specified otherwise in individual sub-clauses.

All test cases in this clause shall be performed either in CS mode or in CS and PS mode.

If the test cases are to be executed in CS and PS mode the System Simulator behaviour in PS mode should reflect the behaviour of a real network. This means that test cases which initially force the UE into the MM IDLE UPDATED state should force the UE in parallel to enter the GMM REGISTERED state. Test cases which initially reject a UE’s attempt to get CS registered, should as well reject a UE’s attempt to get PS registered.

The following consequences arise from supporting this type of behaviour:

1. GMM ATTACH REQUEST messages received in the preamble should be accepted and bring the UE into the GMM REGISTERED state

2. subsequent GMM ATTACH REQUEST messages received in the test body should be rejected with Cause value = 7 ‘GPRS services not allowed’ (see NOTE).

3. within the test body GMM ROUTING AREA UPDATE REQUEST messages may be received and should be acknowledged resp. rejected the same way as the corresponding LOCATION AREA UPDATING REQUEST messages (see NOTE).

4. GMM DETACH REQUEST messages received within the test body should be acknowledged.

5. if, at the beginning of a test case, a UE attempts to register in CS mode, and this attempt is rejected, the parallel attempt to register in PS mode should be rejected with the same cause as used to reject the CS registration

In PS mode the UE may attach automatically or not. This should be accounted for by the System Simulator. A manual Attach UE will not be triggered to perform PS registration for subsequent switch on of the UE, in the test body.

Any GMM signalling shown in the Expected Sequence Tables in the following sections is purely informative and shall not be considered to be part of the test purpose or test requirement.

NOTE: A Rel-8 UE supporting E-UTRA and CS voice emergency call may send ‘signallingConnectionReleaseIndication’ upon receipt of an ATTACH REJECT or a ROUTING AREA UPDATE REJECT message with one of the following causes: ‘Illegal MS (cause #3)’, ’GPRS service not allowed (cause #7)’ or ‘GPRS services and non-GPRS services not allowed (cause #8)’.
