Patent ID: 8830897

Claim:
A method performed by a user terminal for handover of wireless communications from a current wireless network to a target wireless network, the method comprising: identifying a target wireless access point (AP) on the target wireless network, and acquiring a tunnel destination address according to an identity of the target wireless AP, wherein the tunnel destination address is an Internet Protocol (IP) address of a signaling forwarding entity; establishing a tunnel according to the tunnel destination address for transmitting network communication data between the user terminal and the target wireless AP through the current wireless network, wherein the tunnel comprises a first signaling transmission tunnel through the current wireless network established by the user terminal with the signaling forwarding entity, a second signaling transmission tunnel between the signaling forwarding entity and a target network acess controller (AC) of the target wireless network, and a third signaling transmission tunnel between the target network AC and the target wireless AP,; executing a network access operation with the target wireless AP through the tunnel between the user terminal and the target wireless AP to set up wireless access to the target wireless AP; and switching to wireless communications with the target wireless AP.
