Section: 6.1.3.9 MBMS context deactivation
Content: The purpose of this procedure is to deactivate an existing MBMS context in the MS and the network. The MS shall only initiate the MBMS context deactivation when requested by the network, however the trigger for the deactivation request by the network may be initiated by the MS at application layer or by the network, see 3GPP TS 23.246[ Multimedia Broadcast/Multicast Service (MBMS); Architecture and functional description ]  [106]. After a successful MBMS context deactivation, the associated MBMS NSAPI and TI values shall be released in both the MS and the network and can be reassigned to another MBMS context. The MBMS context deactivation procedure makes use of the messaging and signalling of the PDP context deactivation procedure as described in the subclauses 6.1.3.9.1 and 6.1.3.9.2.
