Abstract
Abstract Intelligent allocation of wireless resources can help avoid the problems of dropped calls in a mobile communications network. A service for allocating resources is designed to develop profiles of subscribers' mobility. That is, profiles are developed for routes, traveled by subscribers at certain days and times. For example, some subscribers commute to and from work at relatively fixed times. By compiling this information in the profile and tracking the movement of the subscriber, the mobile network can anticipate the subscriber's movement into a next cell. Thus, wireless resources in the next cell can be reserved prior to the anticipated handover of an ongoing call involving the subscriber. Thus, uninterrupted service can be maintained and dropped calls can be avoided.
