Abstract:
PURPOSE: An IPC(Inter Processor Communication) method through a LAN(Local Area Network) IPC network using a broadcasting packet transmission scheme is provided to improve the efficiency and performance of a distributed system by using an Ethernet as an IPC network and using distributed IPC key information for expanding an IPC mechanism. CONSTITUTION: A request node judges whether a function call is a function call for generating connection setup or a function call for releasing the connection setup(402). If the function call is the function call for generating the connection setup, the request node transmits a connection setup generation request packet as a broadcasting packet to a referee node and any nodes(403). If a response packet is received(404), the request node judges whether the response packet is a connection setup generation admission packet or a connection setup generation failure packet(405). If the response packet is the connection setup generation admission packet, the request packet transmits a connection setup generation informing packet as a broadcasting packet to the referee node and the any nodes(406).

Abstract:
A handover method for selecting an access network based on user preference in a mobile node and an apparatus thereof are provided to perform handover first with a PoA(Point of Access) suitable for a preference condition of a mobile node user, thereby increasing use efficiency of the access network. A network selection input unit(410) inputs an access network preference condition. An event generation detector(420) detects a medium independent handover event. A handover information obtaining unit(430) receives medium independent handover related information about a plurality of access networks. An access network setting unit(440) determines and sets priority of an access network in which handover will be performed. A medium independent handover processor(450) processes a connectable point and medium independent handover.

Abstract:
A method and an apparatus for managing access router information for fast three layer handover, and a network system using the same are provided to maintain the capacity of an information table managed by an adjacent access router constantly regardless of the number of PoA(Point of Attachment) and have no need to update an information table even when the PoA is added, replaced, or removed, thereby managing access router information more efficiently. An AR1(Access Rounter1) collects CoA(Care of Address) of three layer information and SSID(Service Set Identification) of two layer information, and transmits a registration request message having the collected information to an adjacent access router management server, and requests the adjacent access router management server to register the collected information(S1,S2). The adjacent access router management server registers the AR1 transmitting the registration request message and stores the CoA and the SSID in an access router management table, searches and acquires neighbor ARs adjacent to the AR1 referring to the adjacent access router management table, acquires the CoA and SSID of the acquired neighbor ARs, and transmits a registration response message including the acquired CoA and SSID to the AR1(S3,S4,S5) The AR1 receives and analyzes the registration response message, and extracts and stores the CoA and SSID of the neighbor ARs(S6). The AR1 transmits an information update request message to the adjacent access router management server if at least one of the CoA and SSID of the AR1 is changed(S7). The adjacent access router management server updates information about the AR1 stored in the adjacent access router management table referring to the information update request message and transmits an information update response message to the AR1(S9,S10). The adjacent access router management server searches the neighbor ARs of the AR1 referring to the adjacent access router management table, and transmits an information update request message having the changed information of the AR1 to each of the neighbor ARs(S11,S12-1,S12-2). The neighbor ARs update the prestored AR1 information and transmit an information update response message to the adjacent access router management server(S13-1,S13-2).
