摘要

When a connecting destination base station apparatus included in a message including an identifier of a base station apparatus serving as a connecting destination of a mobile station apparatus is different from a connecting source base station apparatus stored in an EPS bearer context, rearrangement of local PDN connection is requested to an L-PGW unit of the connecting destination base station apparatus and local PDN connection is deleted. After establishment of a wireless bearer is completed between the mobile station apparatus and the connecting destination base station apparatus, the connecting destination base station apparatus is instructed to start proxy transmission of neighbor advertisement instead of the mobile station apparatus. In base stations that support local IP access, when UE performs service request processing or handover processing between home base stations, it is possible to continue communication session using local IP access while suppressing alterations to existing system to the minimum.
