Abstract

A method for establishing a communication of the IP multimedia subsystem in local routing mode where user data are routed directly at one or more interconnected satellites, without passing through the ground, between two UE terminals connected to a regenerative satellite of a communication network comprising a satellite constellation. A session control function of the IMS core network interrogates a server linked to the satellite constellation with the information relating to the satellite access networks of the two terminals. The server is able to determine, by verification of an inter-satellite link between the regenerative satellites corresponding to the information relating to the satellite access networks of the two terminals, whether local routing of the user plane without passing through the ground is available to directly connect the two terminals are connected by link.
