5.5.11.0 General
The following conditions apply throughout clause 5.5.11:
Table 5.5.11.0-1: Conditions
Condition |
Explanation |
FA |
IE for when an active Functional Alias is used |
ACK |
Message requests a Transmission control Ack |
UPLINK |
The message is sent from the UE |
DOWNLINK |
The message is sent from the SS |
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 5.5.11. 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 (MCVideo client) cannot be controlled, specifying a "hard coded" value to be used by the SS (MCVideo Server) or the SS-UE (MCVideo 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 MCVideo test case definitions e.g. in TS 36.579-6 [84] 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 36.579-6 [84] no explicit SSRC values are defined.
