CA 2686807

This invention addresses the need to transport high bit-rate data to multiple users, or between users, over wired and wireless means. Specifically, this disclosure describes a new method of enabling communication from mobile phone to mobile phone when no network services are available as long as radio contact between the mobile handsets is possible by reserving un-assigned timeslots in the medium access control protocol super frame structure.

Le protocole de l'invention répond au besoin de transporter des données à haut débit vers de multiples utilisateurs, ou entre eux, par des moyens filaires ou sans fil. Cette invention décrit, plus particulièrement, un nouveau procédé permettant d'établir une communication de téléphone mobile à téléphone mobile lorsqu'aucun service de réseau n'est disponible aussi longtemps qu'un contact radio entre les combinés mobiles est possible par réservation d'intervalles de temps non attribués dans la structure de super-trame du protocole de commande d'accès au support.
