7.11 Simultaneous session for MCVideo calls (on-network)

23.2813GPPFunctional architecture and information flows to support Mission Critical Video (MCVideo)Release 18Stage 2TS

An MCVideo client and MCVideo server may use a simultaneous session as defined in 3GPP TS 23.280 [6] for MCVideo calls. The MCVideo client becomes involved in a simultaneous session for MCVideo calls by inviting, joining or accepting more than one MCVideo call, or affiliating to a group.

NOTE: An MCVideo client affiliating to multiple MCVideo groups with active calls will result in the MCVideo client being invited simultaneously to multiple MCVideo calls.

The MCVideo client can also still handle multiple MCVideo calls in parallel at the same time i.e. using multiple dialogs.

The simultaneous session is established during either an originating on-demand call establishment or during pre-established session establishment or a modification of an already established pre-established session or on-demand call.

It is possible to change the prioritisation while the MCVideo client is engaged in multiple MCVideo calls. The setting of the priority can be made at MCVideo call setup or by performing a modification after the MCVideo call is established. This may result in more than one media bearer.
