COMMUNICATION SYSTEM, MOBILITY MANAGEMENT ENTITY, BASE STATION, AND COMMUNICATION METHOD

摘要

Upon detecting an opportunity to release E-RABs related to mobile stations, a mobility management entity transmits a single E-RAB release information message that collectively specifies E-RABs to be released to a base station communicating with the mobile stations. Subsequently, upon receiving the E-RAB release information message, the base station transmits a single E-RAB release information acknowledge message to the mobility management entity. Upon receiving the E-RAB release information acknowledge message, the mobility management entity updates information related to the E-RABs so that the information indicates release of the E-RABs.
