摘要： A wireless system includes plural different access networks and terminals (19, 20) having interfaces corresponding to the plural different access networks (3, 5, 9, 13). Each of the access networks includes an access gateway (AGW) performing flow control. Upon receiving a packet transmission stop signal, the AGW determines whether a predetermined message transmitting chance is given. The AGW includes a control unit that transmits a message that requests a handover to another access network to a terminal when the message transmitting chance is given. The terminal includes a unit that performs a handover to another access network, upon receiving the message.

摘要： In a mobile communication system including an access gateway (AGW) comprising a C-AGW for handling control messages and a plurality of U-AGWs for forwarding data packets, the C-AGW is provided with a management table indicating an address of U-AGW to be an endpoint of tunnel, in association with each of mobile station IDs. When a tunnel setup request message including a mobile station ID is received from one of base stations, the C-AGW searches the management table for the address of U-AGW corresponding to the mobile station ID and notifies the base station of the U-AGW address, and if the mobile station ID is not found in the management table, the C-AGW notifies the base station of an address of a particular U-AGW selected out of the U-AGWs, so that the base station establishes a tunnel for forwarding data packets toward the notified U-AGW.

摘要： Disclosed herewith is a wireless system capable of reducing packet sending delay occurrence and packet sending delay jittering at the time of hand-over processing executed therein. In the wireless system, upon estimating occurrence of a hand-over event, a subject mobile station and its base station extend the packet buffering period respectively and furthermore, the base station changes the current burst scheduling method for another. The base station and the mobile station then exchanges messages required to execute the hand-over procedure in a period between when sending of a burst ends and when sending of the next burst begins.
