Figure 6.2.1-1 below is the on-network architectural model for the MC system solution, where the MC system provides one or more MC services via a single PLMN.
The SIP core provides rendezvous (contact address binding and URI resolution) and service control (application service selection) functions, as described in
clause 5.3.
The 5GS provides data connectivity and services with QoS control for the support of MC service sessions.
UE 1 is an MC service UE in on-network mode supporting data connectivity and application(s) related to one or more MC services over the 5GS, or an UE that acts as 5G ProSe UE-to-network relay, or both of the above. It is composed of the corresponding MC service functional entities described in
clause 5.
UE 2 is a device using 5G ProSe UE-to-network relay, and supporting application(s) related to one or more MC services. It is composed of the corresponding MC service functional entities described in
clause 5.
