26.7.5.1 Introduction

[tbd]

26.7.5.2 MM connection / establishment with cipher and repeated FACCH

26.7.5.2.1 Conformance requirement

The Mobile Station shall be able to correctly set up an MM connection in a Mobile Originating CM connection attempt and send a CM Service Request message with CKSN information element as stored in the SIM and Mobile Identity information element set to the TMSI.

The Mobile Station shall be able to interpret cipher mode setting as acceptance of its CM service request i.e. send a CM message.

3GPP TS 04.08 / 3GPP TS 24.008 subclause 4.5.1.1;

The MS shall, when receiving a downlink FACCH block, always attempt to decode it without combining with any previously received FACCH block.

If the current FACCH block is successfully decoded and an identical FACCH block was previously received (successfully decoded and spaced in time from the current FACCH block as specified in sub-clause 10.2), the MS shall not send the LAPDm frame of the current FACCH block to the LAPDm entity.

3GPP TS 44.006 subclause 10.4;

26.7.5.2.2 Test purpose

To verify that the MS can correctly set up an MM connection in an origination and interpret cipher mode setting as acceptance of its CM service request.

To verify that the MS behaves correctly when Repeated FACCH is used by the SS for LAPDm command frames, and additionally where the MS supported repeated FACCH for LAPDm response frames.

26.7.5.2.3 Method of test

Initial conditions

System Simulator:

1 cell, default parameters.

Mobile Station:

The MS has a valid TMSI. It is "idle updated".

Specific PICS statements:

  • at least one half rate service (TSPC_AddInfo_HalfRate)
  • Support of Repeated FACCH (TSPC_Repeated_FACCH)

PIXIT statements:

Foreseen final state of the MS

The MS has valid TMSI, CKSN. It is "idle updated".

Test Procedure

A mobile originating CM connection is initiated. After the MS has sent the CM SERVICE REQUEST message to the SS, an authentication procedure and a ciphering mode setting procedure are performed. Then, the MS sends a CM message and the SS clears the call and releases the channel.

For k=2 and k=3, the SS shall activate Repeated FACCH for LAPDm command frames on FACCH.

If the MS supports Repeated FACCH, the SS shall additionally activate Repeated FACCH for LAPDm response frames on FACCH. It is checked by the SS that the MS does not respond to identical FACCH blocks which are repeated.

If the MS does not support Repeated FACCH, the MS may respond to the identical FACCH blocks which are repeated, with a REJ frame.

This test is repeated for:

k=1;

k=2;

k=3 where the MS supports at least one half rate service.

Maximum duration of test

3 minute.
