Abstract

A repeater for use in a radiocommunication network for relaying data communications between first and second stations between which data communication via the radiocommunication network alone is impossible includes a first converter for converting a first radio signal received from the first station into the form of first receive messages and converting first transmit messages into the form of a first radio signal transmitted to a first station. A second converter converts a second radio signal received from said second station into the form of second receive messages and second transmit messages into the form of a second radio signal transmitted to the second station. An application controller manages the first receive messages and the first transmit messages and the second receive messages and the second transmit messages.

Claims

1. A repeater for use in a radiocommunication network for relaying data communications between first and second stations between which data communication via said radiocommunication network alone is impossible, said repeater including:

first converter means for converting a first radio signal received from said first station into the form of first receive messages and converting first transmit messages into the form of a first radio signal transmitted to a first station,

second converter means for converting a second radio signal received from said second station into the form of second receive message and converting second transmit messages into the form of a second radio signal transmitted to said second station, and

application controller means for managing said first receive messages, said first transmit messages, said second receive messages and said second transmit messages,

wherein said application controller means simulate said first station, respectively for said second station, vis à

vis said second station respectively for said first station such that traffic on said radiocommunication network is reduced.

2. The repeater claimed in claim 1 wherein said application controller means include means for storing in memory identification data received from at least one of said first and second stations for addressing said first station, respectively said second station.

3. The repeater claimed in claim 1 wherein said application controller means include means for producing an interrogation message that is converted by said second converter means into the form of said second radio signal transmitted to said second station.

4. The repeater claimed in claim 3 wherein said application controller means include means for selecting certain second response messages from second response messages received from said second converter means in response to the transmission in the form of said second radio signal of respective interrogation messages and means for producing said certain selected second response messages in first messages transmitted in the form of said first radio signal to said first station.

5. The repeater claimed in claim 1 wherein said application controller means include means for producing acknowledgement messages that are converted by said first converter means into the form of said first radio signal transmitted to said first station.

6. The repeater claimed in claim 1 wherein said radiocommunication network is a satellite network and said application controller means include means for delaying the transmission to said first station via said first converter means of messages received from said second station via said second converter means in accordance with an orbital position of a satellite.
