Summary Handoff support is one of the key elements in cellular Personal Communication Systems (PCS). Traditional approaches hide handoff support from the subscriber. However, the main difficulty in handoff support stems from terminal mobility which can only be controlled by the subscriber, who may again have different requirements of mobility support under different environments. Therefore, we suggest that the subscriber should participate in handoff support in the following manner: first, the subscriber is encouraged to declare the requirement of mobility support at call setup time; second, when a handoff cannot be supported, the subscriber should be informed in advance so that (s)he can decide whether or not to control movement since a subscriber may sacrifice mobility for maintaining communication in progress. This approach can reduce call dropping rate and improve resource utilization. We will describe this approach and propose a service classification for mobility support in this paper.
