NOTE: Flow 7.12-1 is a high level user authentication and authorization flow. 3GPP TS 33.180 [14] defines the specific user authentication and authorization architecture required by the MCVideo service in order to realize the MCVideo user authentication and authorization requirements as defined in 3GPP TS 22.280 [2].

A procedure for user authentication is illustrated in figure 7.12-1. The user authentication is performed based on the procedure specified in 3GPP TS 23.280 [6].
