<p>The method and apparatus of the architecture of the present invention is accomplished in an embodiment of the present invention by establishing a high speed network interconnection layer between the base station and the mobile switching office. This high speed interconnected network may be an asynchronous transfer mode (ATM) switch. This architecture allows for a dynamic virtual cell area to be configured around a mobile subscriber as a mobile subscriber moves within the network. As a subscriber leaves a previously defined virtual cell area into a new virtual cell area, the high speed switching network sets up a new virtual cell area around the mobile subscriber in his new area. The network is designed to anticipate a user's mobility pattern and to set up the new virtual cell area in advance of the mobile subscriber moving into that new area. The network is able to predict the mobile subscriber's future location ahead of time, thus enabling the network to accomplish much of the overhead processing and setup used to accommodate the mobile subscriber before arrival in the new area, thus ensuring a smooth handoff and transition period during a call.</p> |
