BASE STATION, CORE NETWORK DEVICE, TERMINAL, AND COMMUNICATION METHOD

WIPO Patent Application WO/2022/172820

A1

This communication method involves transmitting MBS data by using an individual mode for using a protocol data unit (PDU) session between a UPF 33 and a terminal 10 or a shared mode for using a shared tunnel between a MB-UPF 35 and a base station 20. On the basis of terminal state information regarding the state of a terminal 10 and/or support information regarding support for the shared mode at a target base station 20B for the terminal 10, switching from the individual mode to the shared mode for the terminal 10 is controlled.
