HANDOFF BETWEEN A NARROWCAST CELLULAR COMMUNICATION NETWORK AND A POINT-TO-POINT CELLULAR COMMUNICATION NETWORK

摘要

The communique system for cellular communication networks operates with existing cellular communication networks to provide communique communication services to subscribers. The Communique transmission to an individual subscriber can be managed using the hand off capability of the cellular communication network. Thus, if the subscriber roams out of the narrowcast coverage area, the communique transmission to the subscriber is extended fro m the narrowcast coverage area via an "umbilical" connection on a point-to-poi nt basis using the existing capabilities of the cellular communication network. This enables uninterrupted service for the subscriber even if the subscriber does not continue to remain within the narrowcast coverage area.
