Mobile communication system and method for transmission of connectionless packets

摘要

In a mobile communication system, a gateway (114) is connected to a connectionless data network (115) for receiving a series of packets of same destination. A number of routers (111, 112, 113) are connected to the gateway (114) and a number of wireless access networks (101, 102, 103, 110) are connected respectively to the routers for establishing wireless links with mobile stations. The gateway is arranged to transmit a request message to all of the routers in response to receipt of the packet of first arrival from the data network to request a search for a mobile station specified by the packet. Each of the routers includes a memory (208) for storing location data of mobile stations. Each router makes a search through its own memory in response to the request message, and responds with a reply message to receive the packets of first and second arrival from the gateway if the specified mobile station is found in the memory, and routes the received packets via the corresponding wireless access network to the mobile station.
