Claims
- 1. A method for optimizing the access to a network of communication channels comprising the steps of:
- enabling access to a channel of the network to a caller making a request for sending a message on said channel if no activity has occurred on said channel for a first specified period of time prior to said request from said caller; and
- if an activity has occurred during said first specified period of time, monitoring occupation of said channel until said channel is no longer occupied including the step of verifying, for a second period of time of random specified duration, the the occupation of said channel and returning to said step of monitoring of occupation of said channel when during said second period of time said channel is occupied and, if said channel is not occupied, enabling the access of said channel to said caller at the end of said second period of time of random specified duration.
- 2. The method according to claim 1 wherein when the message from said caller has been sent the method further involves the step of waiting for a third specified period of time for an acknowledgement of reception of said message and terminating the transmission if a correct acknowledgement of reception is received before the expiration of said third specified period of time and if the correct acknowledgement of reception is not received before the expiration of said third period of time, the method involves triggering a fourth period of randomly specified duration and if said channel is occupied at the end of said fourth period of randomly specified duration returning to the step for monitoring occupation of said channel of said network and if said channel is not occupied on the expiration of said fourth period of randomly specified duration said message is again sent.
