Latest Patents
Charles N Lo's latest patents include a method and system utilizing a pointer strategy to locate nomadic users. This innovation aims to improve the process of locating users in a PCS system by employing two strategies and a per-user criterion to determine the most effective approach. The method enhances the basic two-level strategies outlined in IS-41 and GSM standards. One strategy involves forwarding pointers, while the other utilizes per-user location caching. A key criterion in this system is the call-to-mobility ratio (CMR), which compares the average rate of incoming calls to the user's movement rate. Additionally, a variation known as the local CMR (LCMR) focuses on calls received from a specific registration area. This innovative approach reduces the average time and overhead required to locate and deliver information to nomadic users.
