ABSTRACT	We consider per-user profile replication as a mechanism for faster location lookup of mobile users in a Personal Communications Service system. We present a minimum-cost maximum-flow based algorithm to compute the set of sites at which a user profile should be replicated given known calling and user mobility patterns. We then present schemes for replication plans that gracefully adapt to changes in the calling and mobility patterns. 1 Introduction In a Personal Communications Service (PCS) system, users place and receive calls through a wireless medium. Calls may deliver voice, data, text, facsimile, or video information [JLLM94]. PCS users are located in system-defined cells, which are bounded geographical areas. When a user places a call, the PCS infrastructure must route the call to the base-station located in the same cell as the callee. The base-station then transmits the data in the call to the PCS unit through the wireless medium. We consider the problem of locating users who...	user correction - Legacy Corrections
