Abstract: A network controller for facilitating roaming of a mobile wireless communications device between access points communicates with at least one access point over a wired network which, in turn, communicate with a mobile wireless communications device over a wireless network. The network controller includes a data processing system including a protocol stack that facilitates a communication session between the mobile device and a network device on the wired network, and a session table identifying session information for each said communication session. The session information identifies the current access point with which the mobile device is currently associated. The protocol stack updates the session table from session information received from the current access point, maintains a first virtual circuit with the network device, maintains a second virtual circuit with the current access point, and bridges communication between the virtual circuits in accordance with the session information.

Abstract: A wireless network communication system consists of an access server for facilitating communication between a network resource interfacing with the access server over a land-based network and a wireless communications device interfacing with the access server over a wireless network. A message intended for transmission from the wireless communication device to the network resource is transmitted to the access server over a wireless network as a number of message datagrams. Upon receipt of the message datagrams over the wireless network, the access server generates and transmits to the wireless communication device an acknowledgement datagram indicating successful receipt of each message datagram, and transmits the successfully received message datagrams to the network resource over the land-based network.
