When a connection destination base station device included in a message containing the identifier of a base station device to be a connection destination for a mobile station device is different from a connection source base station device stored in an EPS bearer context, the connection destination base station device requests reassignment of a local PDN connection with respect to an L-PGW unit of the connection destination base station device and deletes the local PDN connection. Then, once a wireless bearer has been established between the mobile station device and the connection destination base station device, the connection destination base station device is instructed to initiate proxy transmission of a neighbour advertisement on behalf of the mobile station device. It is therefore possible for a plurality of home base stations supporting local IP access to continue a communication session using local IP access while alterations to the existing system are kept to a minimum when a UE has performed processing for a service request or processing for handover between the home base stations.
