Method of attachment between at least one mobile network and one remote network

A method for attachment between a mobile broadband cellular radio communications network and at least one remote broadband cellular radio communications network, the method comprising the following steps:

• upon detection of the at least one remote broadband cellular radio communications network by the mobile broadband cellular radio communications network or detection of the mobile broadband cellular radio communications network by the at least one remote broadband cellular radio communication network:
• configuring a first application level, a first authentication and mobility management level, and a first radio management level of the mobile broadband cellular radio communications network in accordance with at least three first inter-network operating models corresponding respectively to the first application level, to the first authentication and mobility management level, and to the first radio management level, the at least three first inter-network operating models being part of a record previously saved in a mobile broadband cellular radio communications network supervision database to attach to the at least one remote broadband cellular radio communications network;
• configuring a second application level, a second authentication and mobility management level, and a second radio management level of the at least one remote broadband cellular radio communications network in accordance with at least three second inter-network operating models corresponding respectively to the second application level, to the second authentication and mobility management level, and to the second radio management level, the at least three second inter-network operating models being part of a record previously saved in a remote broadband cellular radio communications network supervision database to attach to the mobile broadband cellular radio communications network;
• establishing at least one inter-network control channel between one element of the mobile broadband cellular radio communications network and one element of the at least one remote broadband cellular radio communications network and at least one inter-network data channel between one element of the mobile broadband cellular radio communications network and one element of the at least one remote broadband cellular radio communications network in accordance with the at least three first and the at least three second inter-network operating models configured per level;
• and
• attaching a transport link including an inter-network supervision channel established between a network supervision means of the mobile broadband cellular radio communications network and a network supervision means of the at least one remote broadband cellular radio communication network to obtain a single network encompassing first user terminals of the mobile broadband cellular radio communications network and second user terminals of the at least one remote broadband cellular radio communications network, wherein each of the first and second user terminals of the single network is authenticated by the single network,
• wherein the configuring the first application level, the first authentication and mobility management level, and the first radio management level is performed by the mobile broadband cellular radio communications network, the configuring the second application level, the second authentication and mobility management level, and the second radio management level is performed by the at least one remote broadband cellular radio communications network, and the establishing the at least one inter-network control channel and the at least one inter-network data channel and the attaching the transport link are performed by the mobile broadband cellular radio communications network or by the at least one remote broadband cellular radio communications network, and
• wherein the method further comprises, before the configuration of the first and second application levels, analysing the at least three first inter-network operating models, performed by the network supervision means of the mobile broadband cellular radio communications network, to check if at least one first inter-network operating model for the first application level is compatible with at least one second inter-network operating model for the second application level, at least one first inter-network operating model for the first authentication and mobility management level is compatible with at least one second inter-network operating model for the second authentication and mobility management level, and at least one first inter-network operating model for the first radio management level is compatible with at least one second inter-network operating model for the second radio management level, and analysing the at least three second inter-network operating models, performed by the network supervision means of the at least one remote broadband cellular radio communications network, to check if at least one second inter-network operating model for the second application level is compatible with at least one first inter-network operating model for the first application level, at least one second inter-network operating model for the second authentication and mobility management level is compatible with at least one first inter-network operating model for the first authentication and mobility management level, and at least one second inter-network operating model for the second radio management level is compatible with at least one first inter-network operating model for the first radio management level.
