A communication of a first terminal is managed in a communication network comprising subnetworks. The first terminal can communicate with at least one second terminal and at least one subnetwork of the network is accessible via this second terminal. At the level of the first terminal, information relating to resources of the subnetwork which is accessible via the second terminal is received from the second terminal. On the basis of this information, a subnetwork is selected for the communication of the first terminal from among a set of subnetworks of the network comprising at least this subnetwork accessible via the second terminal.

Management of a communication in a heterogeneous network

An access point () for controlling routing in a hybrid network includes a topology table including routes to nodes registered on request with the access point and routes to nodes that have responded to an advertisement message broadcast by this access point () only to nodes having a predetermined status and means for selecting a route from all possible routes between a source node (S) and a destination node (D) determined from the above-mentioned response messages. Only nodes that have not contributed to routing a registration request respond to the advertisement message.

Access point and node for controlling routing in a hybrid network

A gateway () between an ad hoc network () and a fixed network () in a hybrid telecommunications network () selects, from amongst candidate nodes () of the ad hoc network () that are located one hop from that gateway () and that have connectivity with that gateway () above a predetermined threshold, at least one gateway node (') for relaying at least part of the traffic between other nodes () of the ad hoc network () and the gateway ().

Methods and devices for discovering a gateway and for routing towards said gateway in a hybrid wireless network

The method of selecting a wireless access telecommunication network in a global link between a first terminal () and a second terminal () comprises the steps of furnishing context information related to a set of at least one terminal () called context taken from the first and second terminals, and in determining the network selected from context information from the set of context terminals () by following a set of predetermined rules. The context information of at least one reference terminal taken in the set of context terminals includes information related to a local environment of the at least one reference terminal () and the determination of the selected network depends on information related to the local environment of the at least one reference terminal ().
