Abstract

A telephone network provides a system which overcomes the problems with roaming charges and loss of service encountered by users by providing an alternate data message path through Low Earth Orbit (LEO) satellite networks such as Iridium Satellite or Globalstar, or through geosynchronous satellite networks such as Terrestar or Inmarsat. The system includes a cellular telephone handset enhancement to include specific satellite network communication capabilities that work in unison with a novel message routing system to handle the multiple message transport paths available for use by the cellular telephone. Each field user device includes a message exchange delivery algorithm which operates to set the delivery route of messages to select either the cellular telephone network or the satellite network.

Claims

1. A telephone network comprising:

a cellular telephone network capable of sending and receiving data messages with identifiable radio transceiver devices;

a satellite network capable of sending and receiving data addressed to and from single identifiable radio transceiver devices;

a network management resource for controlling communication of messages on the network;

a plurality of field user radio transceiver devices each capable of two-way communications through the cellular telephone network and though the satellite network to the network management resource;

each field user device including a message exchange delivery algorithm which operates to set the delivery route of messages to said network management resource to select either the cellular telephone network or the satellite network.

2. The network according to claim 1 wherein the field user device is arranged to send control messages defining said delivery route to said network management resource according to the rules of the algorithm.

3. The network according to claim 1 wherein the delivery route of communication between the network management resource and each field user devices is controlled solely by the message exchange delivery algorithm of the respective field user device.

4. The network according to claim 1 wherein there is provided a message delivery and reception status repository at the network management resource containing a table to record and report the status of each message to and from each field user device.

5. The network according to claim 4 wherein the field user device is arranged to send control messages to the message delivery and status repository at the network management resource according to the rules of the algorithm.

6. The network according to claim 5 wherein the message delivery and status repository at the network management resource is arranged such that a message delivery acknowledgement message is sent to the field user device when the control message is received from the field unit device.

7. The network according to claim 6 wherein the field user device is arranged to receive the acknowledgement so that the full handshake has occurred so that all messages produced by the field user device are routed through the chosen network.

8. The network according to claim 1 wherein the field user devices are arranged such that an active communication path control message is created by the algorithm which contains the delivery route currently selected by the field user device.

9. The network according to claim 8 wherein the active communication path control message defines the network to be used for all messages to be exchanged with that field user device.

10. The network according to claim 9 wherein the field user device is arranged such that, when that field user device receives an acknowledge message from the network management resource, all messages between the network management resource and that field user device continue to use the selected network until such time that the field user device sends another active communication path control message to change the route to a different network.

11. The network according to claim 10 wherein the field user device is arranged such that when the network is changed to a different network, the process repeats itself and the different network is stored.

12. The network according to claim 1 wherein the field user device is arranged such that the message exchange delivery algorithm which operates to set the delivery route of messages to select either the cellular telephone network or the satellite network is initiated by one or more of powering up the device, a user manually requesting to change networks, or a timeout.

13. The network according to claim 1 wherein the field user device is arranged such that the message exchange delivery algorithm operates to set the delivery route of messages to select either the cellular telephone network or the satellite network if the network used previously is not available.

14. The network according to claim 1 wherein each field user device is able to communicate with the satellite network by having components to communicate with said satellite network integrated within the physical case of the field user device.

15. The network according to claim 1 wherein each field user device is able to communicate with the satellite network by having components to communicate with said satellite network in an accessory as a direct attachment to the field user device.

16. The network according to claim 1 wherein each field user device is able to communicate with the satellite network by having components to communicate with said satellite network in an accessory having a wireless link with the field user device.

17. The network according to claim 1 wherein there is provided at least one point of contact with the capability, both through said cellular network and through the satellite network, to receive and send and otherwise exchange and relay data messages with other points of contact and/or networks of data message exchange mechanisms.
