COMMUNICATION CONTROL METHOD AND COMMUNICATION SYSTEM

WIPO Patent Application WO/2019/193763

A1

This communication control method is carried out in a communication system in which a plurality of slices are generated, the slices being virtual networks logically generated on a network infrastructure. Said communication system is configured to include: a terminal (UE); a plurality of base station nodes (RAN) that manage connections to the slices by the terminal; and a communication control node (AMF) that performs communication control by the terminal. Said communication control method comprises: a step (1) in which the base station nodes or communication control node hold/holds multiple-connectivity permissibility information determined for each slice, the information relating to whether or not to permit multiple connectivity with which the terminal simultaneously wirelessly accesses a plurality of base stations; steps (11, 13) in which the base station nodes or communication control node holding the multiple-connectivity permissibility information transmit/transmits said information to the terminal; and a step (15) in which the terminal connects to one or more of the slices on the basis of the multiple-connectivity permissibility information.
