GPIB Command Conventions

CALL[:CELL]:TMSI[:VALue]

Function GSM TA This command is not applicable to the GSM test applications.

GPRS TA

This command is not applicable to the GPRS test applications.

EGPRS TA

This command is not applicable to the EGPRS test applications.

GSM/GPRS LA

This command sets/queries the TMSI (Temporary Mobile Subscriber Identity). TMSI is described in 3GPP TS 23.003 Section 2.4, which states that "The network shall not allocate a TMSI with all 32 bits equal to 1 (this is because the TMSI must be stored in the SIM, and the SIM uses 4 octets with all bits equal to 1 to indicate that no valid TMSI is available)."

This parameter can only be set while the Call Status is Idle and the Data Connection Status is Idle. (Manually setting the TMSI value requires the TMSI Assignment parameter to be On .)

When the TMSI Assignment is set to On , the TMSI value setting determines the TMSI that is assigned to the mobile station during the Location Area Update procedure, combined GPRS / IMSI Attach procedure, or Routing Area Update procedure (see Call Processing Ladder Diagrams ). The command to set the is TMSI Assignment is CALL[:CELL]:TMSI:ASSignment .

When the CS Paging Identity Type is set to TMSI , this setting determines the TMSI that is used to page the mobile station. The command to set the is Paging Identity Type is CALL:PAGing:IDENtity[:TYPE] .

The TMSI value used for both test sets in a Two-Cell Test System is the TMSI setting in the test set that initiates the External Device Connection.

EGPRS LA

Setting

Range: 0 to 4294967294 (Note: The value 4294967295 (or 232 - 1) is reserved by the mobile station to indicate that it does not have a valid TMSI stored.)

Resolution: 1

Query

Range: 0 to 4294967294

Programming Example

 
OUTPUT 714;"CALL:TMSI 1234567890" 
! Sets the TMSI value.

CALL[:CELL]:TMSI:ASSignment

Function GSM TA This command is not applicable to the GSM test applications.

GPRS TA

This command is not applicable to the GPRS test applications.

EGPRS TA

This command is not applicable to the EGPRS test applications.

GSM/GPRS LA

This command sets/queries whether the test set assigns a TMSI to the mobile station during the Location Area Update, Routing Area Update, and Combined GPRS/IMSI Attach procedures. If the TMSI Assignment is set to On , the mobile station is assigned the TMSI value when it registers with the test set.

This parameter can only be set while the Call Status is Idle and the Data Connection Status is Idle.

You must set TMSI Assignment to On before the mobile station registers in order for the TMSI to be assigned.

The command to set the Operating Mode is CALL:OPERating:MODE .

The command to set/query the TMSI value is CALL[:CELL]:TMSI[:VALue] .
