摘要： When a mobile terminal transmitting/receiving a packet using a plurality of IP address types performs a handover to an access network (single address type connection network) permitting transmission/reception of a packet using a single IP address only, an IP address not permitted is unfortunately discarded at an access network as a handover destination. Disclosed is a technique configured so that a mobile terminal (UE 1) detecting a handover to the single address type connection network establishes a temporary connection with a mobility management gateway (PGW 5) and thereafter acquires an address of an ePDG 8 located at a core network and informs the ePDG of a communication state before the handover via a PDN using the temporary connection. The ePDG informs the PGW of the communication state of the UE before the handover. Thereby, the communication state of the UE before the handover is achieved with the PGW via the ePDG and the PDN.

摘要： A positioning server device comprises: an input unit which receives measurement information of radio waves which are transmitted between an access point and a client; a radio wave map administration unit (10) which administers radio wave map data which denotes an estimation of a correspondence relation between the radio wave measurement information and a spatial location; and a positioning unit (13) which positions the location of the client based on the radio wave measurement information and the radio wave map data. The radio wave map administration unit (10) administers first map data which relates to a fixed positioning range where it is possible for a client to be positioned to be present conventionally, and second map data which relates to an extended positioning range wherein a possibility arises that the client to be positioned may be present according to particular conditions, as radio wave map data.

摘要： The present invention introduces a method for the network to optimize the route for user's local IP access, without affecting the access to operator's core network. With this mechanism, no excessive signalling is needed for the optimization. The present invention is also applicable to the corporate network that has multiple home NodeBs or home eNodeBs. Finer grain control on the services to be provided over different home NodeB or home eNodeB is also possible. Further, path optimization and continuation of the service upon handover can be controlled, and hence flexibility of the service can be secured.

摘要： In a mobile communication system utilizing Mobile IP, information on the access network is exchanged between access routers. And when a mobile terminal performs a handover, the previously exchanged information on the neighbor access routers and the access network information are provided to the mobile terminal. By so doing, the mobile terminal can determine a destination access router in advance, enabling to realize an efficient handover processing.

摘要： A home gateway device having a home agent function selects communication interfaces other than the communication interface which has acquired network information for setting a home network to be home links, and appropriately sets the home link and a home agent by using the acquired network information, thereby reliably achieving the automatization of the device setting. Moreover, the home gateway device selects a link connected to a mobile terminal based on a mobile IP as home link, acquires existing home agent information from the mobile terminal and makes settings with this information, thereby setting the home link without compelling the mobile terminal to change its setting.

摘要： A technology is disclosed that provides a handover method and the like capable of improving communication efficiency by detecting that a handover destination network is a home link at an early stage and reducing tunnel overhead between a mobile node and a home agent. The technology includes, when the mobile node performs a handover from an access router of a network before the handover to which the mobile node is currently connected, to an access router of another network that is a handover destination: a step of transmitting, by a mobile node 107, an address allocation request message for acquiring an address in the handover destination network allocated to the mobile node, to the access router of the handover destination; and a step of transmitting, by a home agent 106 of the mobile node, a notification message including information indicating a type of the address of the mobile node allocated by an address allocation server of the handover destination or the home agent as a result of the address allocation request message, to the mobile node via the access router before the handover.

摘要： A router, if judging that a routing function is impossible to execute, sends out a connection instruction message including the address of a terminal on a local network terminating the relaying flow, to another router to solicit switching. The router having received the connection instruction message starts a process for connecting with an external network while executing a process for link connection with a terminal, and then sends out a connection completion notice message when the connection with both the external network and the terminal is established. This process enables the router to switch a path rapidly.

摘要： In a mobile communication system using a mobile IP, a mobile terminal determines a main home agent and a main home address. When the mobile terminal moved to a network different in service form, a home address for use on a moved-in domain network is registered as a primary care of address to the main home agent, thereby enabling communications by using the main home address even upon accessed from the other than the belonging domain network. This makes it possible to flexibly cope with an incoming call from the external by the use of a representative home address even on the Internet as a distributed network.
