Section: 6.1.3.9.1 MBMS context deactivation initiated by the network
Content: In order to request an MBMS context deactivation, the network sends a DEACTIVATE PDP CONTEXT REQUEST message to the MS, enters the state MBMS-INACTIVE-PENDING and starts timer T3395. The message contains the transaction identifier (TI) in use for the MBMS context to be deactivated and a cause code that typically indicates one of the following causes: # 36: regular deactivation; # 38: network failure; # 47: multicast group membership time-out. The MS shall reply with a DEACTIVATE PDP CONTEXT ACCEPT message and enter the state PDP-INACTIVE. Upon receipt of the DEACTIVATE PDP CONTEXT ACCEPT message, the network shall stop the timer T3395 and enter the state PDP-INACTIVE.
