Abstract: The disclosed technology relates to a method of rebooting a residential gateway. In one aspect, the residential gateway is connected, on the one hand, to a wide-area communications network and, on the other hand, to a local-area network in which the gateway implements the method in a consecutive order of: receiving a first action message comprising at least one order to shut down the gateway, the first action message being generated by an execution entity of the wide-area communications network and transmitted on the data link layer; storing a context of configuration of the local-area network associated with the gateway; shutting down the gateway; and rebooting the gateway according to the context of configuration previously stored.

Abstract: A service continuity method includes a step of detecting a fault consisting in at least one service to which a residential gateway normally provides access no longer being accessible or in the quality of service of at least one service to which a residential gateway normally gives access being degraded. The method further includes, after detection: a) a supervision center (CSC) selecting at least one mobile relay; b) the supervision center (CSC) communicating at least one instruction to the selected mobile relay for the purpose of ensuring continuity of the service; c) the mobile relay setting up a session association with the gateway or with an intermediate device; and d) the traffic relating to the service being redirected to the mobile relay.

Abstract: To enable a visitor network to access a host network, a method includes steps in which a router of a visitor network connects to a router of a host network and transmits to it an address request message containing an identifier of the visitor router. The host router extracts, from the address request message received, the identifier of the visitor router, and transmits, to the visitor router, an address assignment message containing either an address or an address prefix of the host network, depending on the identifier of the visitor router extracted from the address request message.

Abstract: The invention concerns a method wherein the mobile node (1) obtains respective temporary addresses with several access routers (3) of a telecommunication system detected by the mobile mode. It also collects data concerning the characteristics of said access routers, and transmits to a manager temporary addresses (6) of a mobility service provider a request for address selection (REQ) containing part at least of the collected data. The manager (6) processes said request to select one of the temporary addresses for the mobile node.

Abstract: A method supervises at least one tunnel set up for routing packets between a mobile router and a referring piece of equipment in a home network of the mobile router. The method detects a change in an availability state of the tunnel and sends notification of the change in the availability state of the tunnel to at least one node connected to the mobile router, and uses the tunnel set up for routing packets between itself and a network.
