System and method for allowing skip zone switch of mobile equipment IP address

The invention relates to a system and a method; wherein, a movable device can be switched from one access point to other access point by spanning areas and simultaneously the continuous communication with the network is kept and the IP address of the device is not changed. In an embodiment, when the device is leaving an interface in the air of the access point for the attributed region of the device, the device sets up a connection with a middle access point. In an embodiment, the communication from the network is conducted to an original access point by utilizing the original IP address of the device and transmitted to the device through the middle access point. The communication form the device is directly connected with the network by a route through the middle access point or connected with the network through the access point for the attributed region. The switch by spanning areas of the IP address is repeated in the middle access point until the device returns to the access point for the attributed region or stops the communication with the network.
