ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to satellite communication systems. Specifically, the present invention relates to geosynchronous (GEO) and Non-geosynchronous (Non-GEO) satellites and more specifically global message delivery systems.
BACKGROUND OF THE INVENTION
Communication systems have been developed using terrestrial based and space based equipment in which subscribers use various devices (e.g., a cellular telephone or pager) to communicate with other subscribers within the communication system. These devices communicate with the system via several communications processes, each involving an exchange of messages between the subscriber and the system.
In some cases, communication systems have been established using Geosynchronous (GEO) satellites, and in other cases, communications systems have been established using Non-Geosynchronous (Non-GEO) satellites. In some existing satellite communications systems, message delivery services are provided for registered subscribers. Registration is necessary to keep track of the subscribers so that the system knows where to send messages for a particular subscriber.
However, existing satellite systems do not provide access to both GEO and Non-GEO satellites. Message delivery systems could become more efficient if both GEO and Non-GEO satellites were used. Procedures for allowing simultaneous access to GEO and Non-GEO satellites should provide an efficient use of satellite resources to deliver messages worldwide.
Thus, what are needed are a method and apparatus for using GEO and Non-GEO satellites to deliver messages (pages) on a global basis. What is also needed is an improved message delivery system and method.
