The EPS bearer considerations specified in subclause 126.96.36.199 of TS 23.280
For an MCVideo call session request, resources shall be requested utilising interaction with dynamic PCC. The MCVideo system shall request resources over Rx to a PCRF. It is recommended that the dedicated bearer(s) for video media and control of the video media (i.e. MCVideo-4 and MCVideo-7) utilise the QCI values depending on the MCVideo mode of the MCVideo call/session, as per Table 5.5.3-1
. For transmission and reception control signalling, the QCI value of 69 is recommended as specified in TS 23.203
. The request of resources over Rx shall include an application identifier for MCVideo in order for the PCRF to evaluate the correct QCI.
The MCVideo audio media and video media may transmit over separate EPS bearers, in which case the priority for each bearer is determined by the operator policy. Depending on operator policy, the MCVideo system may be able to request modification of the priority (ARP) of an existing bearer without the need to initiate a new dedicated GBR bearer.
When MCVideo audio media and video media are multiplexed into one EPS bearer, then different QCI and/or ARP values are not possible for video and audio media.
The MBMS bearer management for MC services is specified in subclause 188.8.131.52 of TS 23.280
