When MBS information is updated, a base station transmits a first message to a terminal. The first message includes a service flow update indicator for indicating a scheme for describing a current MBS identifier (ID) and flow ID to be updated, information on the current MBS ID and flow ID described by the scheme indicated by the service flow update indicator, and new MBS information. The terminal transmits a second message to the base station in response to the first message. |
