Method of ensuring continuity for services supplied by a residential gateway

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.
