Patent

CA 2583871

A method is provided for broadcasting a packet over multiple dissimilar wireless networks, at least one of the networks natively supporting broadcasting and at least one of the networks not natively supporting broadcasting. The method includes determining whether the packet is to be broadcast (S14); and when the packet should be broadcast, determining recipients of the packet (S18). A current network over which the packet will be broadcast is then selected based upon the determined recipients (S20). Subsequently, it is determined whether the current network (S24) supports broadcasting. When the current network does not natively support broadcasting, the packet is individually sent to each recipient over the current network (S36). When the current network does natively support broadcasting, the packet is broadcasted to the recipients over the current network (S26).

L'invention concerne un procédé de diffusion de paquet sur plusieurs réseaux sans fil dissemblables, au moins l'un d'eux assurant d'origine la diffusion et au moins l'un d'eux n'assurant pas d'origine la diffusion : détermination de la nécessité de diffusion du paquet considéré (S14); si nécessité. Détermination des destinataires (S18) ; puis choix de réseau opérationnel de diffusion, selon les destinataires déterminés (S20) ; ensuite, déterminationvisant à établir que ledit réseau (S24) assure la diffusion. Lorsque ce réseau n'assure pas la diffusion d'origine, le paquet est transmis individuellement à chaque destinataire sur le réseau en question (S36). Dans le cas inverse, la diffusion intervient pour les destinataires sur ce réseau (S26).
