Methods for registering a mobile terminal by means of an ip network access router, for managing the mobility of a terminal in an ip network, and for configuring a mobile terminal

Abstract : The invention relates to methods for registering a mobile terminal by means of an IP network access router, for managing the mobility of a terminal in an IP network, and for configuring a mobile terminal. The invention proposes to assign a multicast group identifier solely to an IP network mobile terminal. Said multicast group identifier enables the creation of: a multicast address that acts a regional temporary IP address of the mobile terminal and is registered with the home agent thereof; and a multicast tree that associated with the multicast address to which the access routers of a remote network, visited by the terminal, subscribe in order to receive the data packets intended for the terminal and easily route said data packets to said terminal. The invention enables the optimization of the handover procedures in an IP network by relying on a hierarchical structure for the visited networks, local management of the mobility in said networks, and use of multicast communication protocols.
