Test Procedure

A mobile originating CM connection is attempted. After the UE has sent the CM SERVICE REQUEST message to the SS, the SS responds with a CM SERVICE REJECT message with reject cause "requested service option not subscribed". It is checked that the UE does not send a layer 3 message via the rejected MM connection.

9.5.5 MM connection / establishment rejected cause 4

9.5.5.1 Definition

9.5.5.2 Conformance requirement

The CM SERVICE REQUEST message contains the:

– mobile identity according to clause 10.5.1.4;

– mobile station classmark 2;

– ciphering key sequence number; and

– CM service type identifying the requested type of transaction (e.g. mobile originating call establishment, emergency call establishment, short message service, supplementary service activation, location services)

If a CM SERVICE REJECT message is received by the mobile station, timer T3230 shall be stopped, the requesting CM sublayer entity informed. Then the mobile station shall proceed as follows:

– If cause value #4 is received, the mobile station aborts any MM connection, deletes any TMSI, LAI and ciphering key sequence number in the SIM, changes the update status to NOT UPDATED (and stores it in the SIM according to clause 4.1.2.2), and enters the MM sublayer state WAIT FOR NETWORK COMMAND. If subsequently the RR connection is released or aborted, this will force the mobile station to initiate a normal location updating). Whether the CM request shall be memorized during the location updating procedure, is a choice of implementation.

9.5.8.3.5 Test requirement

At step 8 the UE shall not send any layer 3 message.

After step 9:

The UE shall send CALL CONFIRMED message if the UE supports a basic service on TCH.

The UE shall send RELEASE COMPLETE message if the UE does not support a basic service on TCH.

9.5.9 MM connection / abnormal cases / CS domain barred because of domain specific access control

9.5.9.1 Definition

This test is applicable for Rel-5 UEs supporting DSAC and Rel-6 or later UEs.

9.5.9.2 Conformance requirement

TS 24.008 clause 4.1.1.2.2

If the PS or CS domain is barred because of domain specific access control, a GPRS MS operating in mode A or B in a network that operates in mode II or III shall use the MM specific procedures or GMM specific procedures, respectively, in the domain which is unbarred. If the MS detects that a domain changes from barred to unbarred, it shall behave as specified in subclauses 4.4.4.9, 4.5.1.2, 4.7.3.1.5, 4.7.5.1.5, and 4.7.13.5.

TS 24.008 clause 4.5.1.2

e) Access barred because of CS domain specific access control

The MM connection establishment shall not be initiated. The MS stays in the current serving cell and applies normal cell reselection process. The MM connection establishment may be initiated by CM layer if it is still necessary, i.e. when access is granted or because of a cell change.

Reference

3GPP TS 24.008 clause 4.1.1.2.2 , 4.5.1.2

9.5.9.3 Test purpose

To test the behaviour of the UE if the CS domain is changed from unbarred to barred because of domain specific access control in a network that operates mode II.

9.5.9.4 Method of test

Initial condition

An access class x (0-15) is arbitrarily chosen. The USIM is programmed with this access class x. The UE is informed that the CS domain specific access class x is barred.

System Simulator:

One cell operating in network operation mode II.
CS domain specific access class x is barred .

User Equipment:

The UE has a valid TMSI and is in idle state .

Related ICS/IXIT statements

Support of DSAC Yes/No.

Test procedure

  1. The CS domain specific access class x is barred: a Mobile Originating CM connection is attempted, but: the MM connection establishment shall not be initiated.
  2. The SS informs the UE by paging that the CS domain specific access class x is not barred: a Mobile Originating CM connection is attempted and the MM connection establishment is initiated, the UE sends a CM SERVICE REQUEST message. Then the UE sends a CM message and the SS clears the call and releases the RRC connection.
