Communique subscriber 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 can be unidirectional (broadcast) or bidirectional (interactive) in nature and the extent of the Communique can be network-wide broadcast or narrowcast, where cells and/or cell sectors are grouped to cover a predetermined geographic area or demographic population or subscriber interest group to transmit information to subscribers who populate the target audience for the narrowcast transmissions. The grouping of cells to form the communique coverage area for the narrowcast transmissions need not be contiguous and can comprise dynamic combinations of contiguous and non-contiguous cells. In addition, 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 from the narrowcast coverage area via an “umbilical” connection on a point-to-point 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.
