5.5.6 Default MCPTT media plane control messages and other information elements
36.579-13GPPMission Critical (MC) services over LTEPart 1: Common test environmentRelease 15TS
5.5.6.1 General
The media plane control protocols messages specified in the present document are based on those specified in TS 24.380 [10] which in term are based on the RTCP Application Packets (RTCP: APP), as defined in IETF RFC 3550 [76].
Depending on the TC scenario, the same MCPTT media plane control message can be sent by the SS or by the UE. Throughout the default content specified in below a particular value has been chosen to satisfy one or the other scenario. It is expected that when a message is used in a TC in a particular context then the relevant for the usage in the TC values will be defined in the TC.
The following conditions apply throughout clause 5.5.6:
Table 5.5.6.1-1: Conditions
Condition |
Explanation |
FA |
IE for when an active Functional Alias is used |
Multi-Talker |
IE for when a Multi Talker call is active |
ACK |
Message requests a Floor Ack |
NOTE: For further conditions see table 5.5.1-1 |
Considerations in regard to describing specific values:
– SSRC
– Synchronization SouRCe (SSRC) values are used in most of the messages specified in clause 5.5.6. The SSRC value is randomly chosen by the participant in, and globally unique within, an RTP session as specified in IETF RFC 3550 [76]. Because the value chosen by the UE (MCPTT client) cannot be controlled, specifying a "hard coded" value to be used by the SS (MCPTT server) or the SS-UE (MCPTT Client) is prone to triggering a collision by choosing a value which may be the same as the one chosen by the UE. How to resolve SSRC collisions is described in IETF RFC 3550 [76] however, resolving them as part of the MCPTT test case definitions e.g. in TS 36.579-2 [2] is not foreseen and is left to the test implementation.
– For the purposes of default and specific messages definition throughout the present specification, as well as, throughout the rest of the MCPTT conformance test specifications e.g. the TS 36.579-2 [2] no explicit SSRC values are defined.
