Procedure for switching traffic to terminal equipment in a low-altitude satellite transmission system and communication system for this procedure

摘要

The present invention relates to a method of traffic switching in a low-orbit satellite communication system with terminals as destination, the connecting of a terminal (13) to a land communication network being accomplished by means of a connecting station (12). The switching of the satellite (11)/terminal (13) and satellite (11)/connecting station links is possible only within a specified zone. The decision to switch the traffic is made as a function of the degradation in the quality of service and of the radio environment around a group of terminals from the said zone. The invention also relates to equipment intended for the use of this method, in particular transmit/receive terminals, as well as land interconnecting stations. Application in particular to the space sector. IMAGE
