CLAIMS

1. A paging communication system, comprising:
terrestrial based communication means for
communicating paging information with a control means and with at least one selective call receiver, the terrestrial based communication means being also capable of communicating the paging information with a satellite based communication means; the satellite based communication means for communicating the paging information to at least one selective call receiver and at least a portion of the terrestrial based communication means;
the control means for determining where and how to deliver the paging information; and
a plurality of selective call receivers, at least some of which are capable of receiving the paging information from the satellite based communication means and the terrestrial based communication means.

2. The system of claim 1 , wherein the satellite based communication means adapts at least a portion of itself to communicate the paging information in accordance with instructions provided by an individual designated to receive the paging information.

3. The system of claim 2, wherein the satellite based communication means adapts at least a paging communication protocol.

4. The system of claim 2, wherein the satellite based communication means adapts at least a paging communication frequency.

5. The system of claim 1 , wherein the terrestrial based communication means includes means for converting the paging information received from the satellite based communication means to accommodate the selective call receiver designated to receive the paging information.

6. The system of claim 1, wherein the selective call receivers operate to monitor the terrestrial based communication means and the satellite based communication means.

7. The system of claim 6, wherein the monitoring
comprises automatically scanning radio frequency channels used by the terrestrial based communication means and the satellite based communication means.

8. The system of claim 7, wherein priority is given to the radio frequency channels used by the terrestrial based
communication means while automatically scanning the radio frequency channels includes used by the terrestrial based communication means and the satellite based communication means.

9. A paging communication system, comprising:
a plurality of terrestrial receivers, at least some of which are capable of receiving paging information from at least one or satellite and from one or more of a plurality of terrestrial stations; the plurality of terrestrial stations being capable of communicating the paging information with at least one satellite, and capable of adapting the paging information so as to be compatible with at least one of the plurality of terrestrial receivers; at least one satellite capable of communicating the paging information to at least one terrestrial station and at least one control station, and further capable of directly transmitting the paging information to at least one of the plurality of terrestrial receivers; and the at least one control station being capable of determining where and how to deliver the paging information.

10. The system of claim 9, which includes a plurality of satellites arranged to form a satellite network capable of adapting at least a portion of itself to communicate the paging information in accordance with instructions provided by an individual designated to receive the paging information.

11. The system of claim 9, wherein at least one of the plurality of terrestrial receivers operate to monitor at least a portion of the terrestrial stations and the satellite network.

12. The system of claim 11 , wherein the monitoring comprises automatically scanning radio frequency channels used by the terrestrial stations and the satellite network.

13. A method for providing a message to one or more areas on a celestial body, comprising the steps of:
at any of a plurality of terrestrial stations:
(a) receiving the message;
(b) transmitting the message to a control station;
at the control station:
(a) receiving the message;
(b) determining where and how to deliver the message;

(c) transmitting the message to at least one of a plurality of satellites orbiting the celestial body;
at any of the plurality of satellites:
(a) receiving the message from the control station;
(b) determining whether to transmit the message toward the celestial body or another satellite;
(c) transmitting the message in accordance with the determination of step (b).

14. The method of claim 13, wherein the control station step of determining where and how to deliver the message comprises the steps of:
(i) e^Ī­mining a memory means to extract information representing preferred message reception instructions; and
(ii) forming message delivery instructions based at least in part upon the information representing preferred message reception instructions.

15. The method of claim 13, which includes the step of adapting the message so be compatible with the selective call receiver prior to the transmission thereof.

16. The method of claim 13, which includes the selective call receiver steps of:
(a) determining whether to monitor at least one of the plurality of terrestrial station and at least one of the plurality of satellites;
(b) operating in accordance with step (a) to receiver the message.

17. A communication system, comprising:
a celestial body having a plurality of individuals thereon, at least some of the individuals having a selective call receiver capable of receiving a message from at least one terrestrial station and from at least one satellite orbiting the celestial body;
the plurality of terrestrial stations positioned on the celestial body for communicating the message to at least one of the selective call receivers and for to a control means via a satellite network;
the control means for receiving the message, determining where and how to deliver the message, and for transmitting the message to the satellites network orbiting the celestial body;
the satellite network comprising at least one satellite arranged to communicate the message toward at least a portion of the celestial body for reception by at least one selective call receiver or terrestrial station.

18. The system of claim 17, wherein the control means includes a memory means for storing information representing user defined message reception preferences.

19. The system of claim 17, wherein each satellite in the satellite network includes means for adjusting transmission characteristics thereof so as to transmit the message only to desired portions of the celestial body.

20. The system of claim 17, wherein each satellite includes means for reducing transmitter power when transmitting information to the control means or any of the plurality of
terrestrial stations.
