Abstract:
1. A system for a mobile wireless communication, comprising: one or more access points, each being accessible from a wireless mobile device, the mobile device being associated with a current access point among the one or more access points; and a network controller for a communication between a network device and the mobile device via the current access point; the network controller comprising: a first protocol layer configured to maintain a first virtual circuit between the network controller and the network device; a second protocol layer configured to maintain a second virtual circuit between the network controller and the current access point; and an intermediate protocol layer configured to bridge a communication between the first virtual circuit and the second virtual circuit through mapping, wherein the second protocol layer is configured to extract a first data segment encapsulated into a second data segment received via the second virtual circuit and pass it to the intermediate protocol layer for transmission to the network device, the first data segment comprising message data from the mobile device and a session number for identifying the network device, wherein the intermediate protocol layer is configured to extract the message data and map the extracted message data to the first virtual circuit based on the session number, and wherein the second protocol layer is further configured to receive data from the intermediate protocol layer and process the received data for transmission to the current access point.
