Abstract
A system and method for facilitating the efficient operation of a mobile station as it transfers from communicating via one wireless data network to another. A session control node is coupled to the mobile node in such a manner that it selectively buffers data being transmitted to the mobile node, at least while the network transfer is being executed. When the mobile node had dropped its communication session with a first wireless network and established a new communication session with a second wireless network, the buffered data is read out and transmitted to the mobile node. The session control node may be coupled with a home network associated with the mobile node or a control node may be associated with the mobile node on an ad hoc basis.
