Patent ID: 8830961

Claim:
A mobile wireless system in which a mobile terminal performs handover between networks in which handover anchor points are different from each other, comprising: first and second gateway nodes which are the different handover anchor points; a first access point device which is able to establish a first communication path and a second communication path with both the first and second gateway nodes simultaneously; and a second access point device which is able to establish a third communication path only with the second gateway node, wherein when the mobile terminal connected to the first access point device and being communicating with a communication destination node using the first communication path passing through the first gateway node switches a connection destination from the first access point device to the second access point device, the first access point device establishes a data transmission path between the first access point device and the second access point device, while maintaining the communication along the first communication path, before the first access point device disconnects the connection from the mobile terminal, and the first access point device transmits data, which has been transmitted from the communication destination node to the first access point device along the first communication path, to the second access point device along the data transmission path, until the connection between the mobile terminal and the first access point device is disconnected, the mobile terminal is connected to the second access point device, and the third communication path passing through the second gateway node and reaching the communication destination node is established.
