13 List of system parameters

3GPP43.069Release 16Stage 2TSVoice Broadcast Service (VBS)

13.1 Timers

13.1.1 Txx

This is a supervision timer on the anchor MSC for the setup of the voice broadcast call. It is started on receipt of a SETUP message from the calling subscriber when the calling subscriber is in the anchor MSC area and on receipt of an ISUP IAM from the relay MSC when the calling subscriber is in the relay MSC area. Refer to subclause 11.3.1.1.2 for procedures on expiry.

The value of timer Txx is operator specific.

13.1.2 Tast

In a network supporting A-interface link sharing timer Tast shall be used to measure the duration between periodic reports from the BSC to the MSC of Group Call Area cells for which channels have been assigned or released, pre-empted or failed since the last periodic report. When timer Tast expires, if new cells in the Group Call Area have been established or existing ones have been released, pre-empted or failed, the MSC shall be informed of the changes (see subclause 7.1b). If no changes have occurred nothing shall be sent. Timer Tast shall be restarted to measure the period of time until the next report. The timer shall be stopped when the call is released.

The value of timer Tast is operator specific. Its default value is 5 seconds.

13.1.3 T3

In a RANflex configuration the group call serving MSC when receiving Send Group Call Info from the VMSC shall supervise the setup of the broadcast call by timer T3. T3 is started when a positive Send Group Call Info result is returned to the VMSC and it is stopped when thebroadcast call is set up. At timeout the temporarily stored transient data are deleted from the GCR.

In a RANflex configuration with group call redundancy T3 shall be implemented in the GCR instead of in the MSC. T3 is started when initial talker information is stored and stopped when initial talker information is deleted. At timeout initial talker information is deleted from the GCR.

The value of timer T3 is operator specific. Its default value is 5 seconds.
