Communication method in a network comprising a primary network and a secondary network
View Patent ↗Communication method between a primary network ( 110 ) and a secondary network ( 24 ), the secondary network comprising a plurality of remote stations ( 210 to 230 ) and having transmission capacities lower than the transmission capacities of the primary network, a base station ( 20 ) enabling data transmissions between the primary and secondary networks. In order to guarantee a quality of service, the method comprises: a creation of at least one virtual wireless channel ( 21 to 23 ), associated with the secondary network with configurable channel parameters, and a routing of the data that transits by said base station to be transmitted to the secondary network according to the virtual channel or channels created. each virtual channel enabling a point-to-point link between the base station and a station of said plurality.
1. A communication method between a primary network and a secondary network, wherein the secondary network comprises a plurality of remote stations and has transmission capacities lower than the transmission capacities of the primary network, a base station enabling data transmissions between the primary and secondary networks,
said method comprising:
creating at least one wireless virtual channel, associated with the secondary network with configurable channel parameters,
each virtual channel being associated to one single station of said plurality of remote stations and enabling a point-to-point link between the base station and said station of said plurality of remote stations, one single virtual channel being associated to one single station,
a single path being formed between a source of said primary network and said station, said single path comprising the single virtual channel associated to said station, and
routing the data that transits through said base station to be transmitted to said station of the secondary network according to the virtual channel created and associated to said station, and
verifying the bitrate available for a transmission of a flow to said station on the virtual channel associated with the station and for authorising transmission of the flow if the bitrate available on the virtual channel is sufficient or rejecting transmission of the flow if the bitrate available on the virtual channel is insufficient.
2. The method according to claim 1 , further comprising:
identifying a data recipient node, and
transmitting data over a virtual channel associated with the recipient node.
3. The method according to claim 1 , wherein at least one part of the remote stations is connected to a plurality of client nodes belonging to the secondary network, each client node being suitable to communicate with a node of the primary network via the connected remote station and the base station, the method further comprising routing data intended for a client node to a wireless virtual channel associated with a remote station associated with said client node.
4. The method according to claim 1 , wherein the channel parameters belong to the group comprising:
bandwidth characteristics,
latency characteristics,
quality of service characteristics, and
classification criteria.
5. The method according to claim 1 , further comprising removing point-to-multipoint links between each remote station of the secondary network and the other stations.
6. The method according to claim 1 , further comprising transmitting a video flow on at least one virtual channel.
