Abstract

An off-load apparatus is disposed between a core network accommodating base stations and the base stations capable of connection with a mobile station. The off-load apparatus includes a storage unit that stores line information and multicast viewing information of the mobile station when the mobile station performs multicast communication of an off-load object via the off-load apparatus; a transferring unit that transfers the line information and the multicast viewing information of the mobile station to another off-load apparatus that is an handover destination when the mobile station moves during the multicast communication; and a control unit that executes a process of participating in multicast viewing on behalf of the mobile station when the off-load apparatus acts as a handover-destination apparatus, based on the multicast viewing information transferred from a handover-source off-load apparatus.
