  • Patent number: 9019894
    Abstract: 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.

  • Patent number: 8885612
    Abstract: When performing a handover from an access network B to an access network A, a UE 10 transmits an attach request to an MME 30. MME 30 establishes a bearer on a first access network based on the attach request. UE 10 requests MME 30 to establish a specific bearer that guarantees the necessary QoS for a flow. MME 30 receives the request for establishment of a specific bearer, establishes a specific bearer that guarantee the QoS for the flow and sets up a path for performing communication of the flow between UE 10 and a PGW 20. This enables the mobile station to select a specific flow among a plurality of flows and be directly handed over to the bearer communication path when the mobile station performs a handover, thus providing a mobile communication system and the like that can realize a handover while maintaining communication quality.
