摘要： A user equipment (UE) is configured with operations to determine whether a network supports non-voice IP Multimedia Subsystem (IMS) services. The UE determines whether a network with which the UE is communicating supports a non-voice IP Multimedia Subsystem (IMS) service and when the network supports the non-voice IMS service, initiates an IMS Protocol Data Unit (PDU) session establishment with the network.

摘要： Embodiments of a Multicast Broadcast Service (MBS) for 5G New Radio (NR). In one aspect, a user equipment (UE) receives first data from a network via unicast, receives first information from the network, the first information indicating the availability of a multicast service, transmits second information to the network and receives second data from the network via multicast in response to transmitting the second information to the network. In another aspect, a UE receives first information from the network, the first information indicating the availability of a multicast service, receives first data from the network via a multicast session and receives second data from the network via a unicast packet data unit (PDU) session.
