Abstract: A method of redirecting data streams exchanged by a mobile terminal associated with a “third-party” account, with a first telecommunications network. The method includes a prior stage including: the first network receiving from the mobile terminal a registration request, and recovering the profile of the third-party account; the first network sending a DNS request including a “redirection” access point name; the DNS system responding by supplying the IP address of a “stream redirection” server; the first network setting up a tunnel between the server and the mobile terminal, by providing the server with at least one identifier of the third-party account; the server supplying a second telecommunications network with which the user of the mobile terminal holds a personal account that is distinct from the third-party account, with at least one identifier of the personal account; and the stream redirection server setting up a tunnel with the second network.

Abstract: A roaming home location server is arranged to receive signalling data communicated between a home location server of a first home mobile radio network and a visitor location server of a second visited mobile network. The signalling data is associated with informing the home location server of the location of a mobile user equipment which has roamed from the first home mobile radio network to the second visited mobile network. The signalling data received by the roaming home location server from the visitor location server of the second visited mobile network includes a request to register the roaming mobile user equipment with the visitor location server of the first visited mobile network.

Abstract: A method of identifying areas for improving radio communications coverage in a mobile radio network under analysis. The method comprises detecting cancel location signalling data, update location signalling data and service signalling data. The cancel location signalling data is generated to cancel a registration of mobile user equipment from a visitor subscriber database of the analyzed mobile radio network. The cancel location signalling data includes mobile subscriber identifiers of the mobile user equipment. The location update signalling data informs the home subscriber database of the home network of the mobile user equipment that the mobile user equipment is to be registered as having roamed to a visitor subscriber database of at least one other mobile network. The location update signalling data includes identifiers of the visitor subscriber database and the mobile subscriber identifier of the user equipment being registered.
