Abstract: An exemplary technique is provided for an initial personalization of a smart card coupled with a communication device of a user. The smart card is configured to send a first request to a home location register that authenticates the user by means of a temporary international identity and a temporary authentication key. The smart card is configured to send a second request for smart card personalization to an application server. The smart card is configured to receive a response from the application server that contains a personalization command, an admin code, an initial international identity and an initial authentication key. The smart card is configured to interpret the personalization command to delete the temporary international identity and the temporary authentication key, and to replace them with the initial international identity and the initial authentication key when the admin code is valid.

Abstract: A smart card associated with a subscription to a first telecommunication network and coupled with a communication is personalized by an application server. The server receives a request of subscription change having an identifier of a second telecommunication network; establishes a secured session with home location register of the second telecommunication network identified by the identifier and receives a first message having a second international identity and a second authentication key from the home location register; and then sends a second message having a personalization command, an admin code, the second international identity and the second authentication key to the communication device. The smart card is able to interpret the personalization command to delete the first international identity and the first authentication key and replace them by the second international identity and the second authentication key if the admin code is valid.

Abstract: The invention concerns a method and a Femto base station for transmitting broadcast services from a radiocommunication cellular network (10) to a mobile terminal (2), said mobile terminal (2) being adapted to receive said broadcast services either, in a first general mode, directly from one global base station (1) among a plurality of global base stations belonging to said radiocommunication cellular network (10), or, in a second specific mode, through a Femto base station (3). According to the invention, said method comprises the step of receiving (S30) at said Femto base station (3) services which are broadcast by the global base station (1) in the coverage of which said Femto base station (3) is located and the step of relaying (S32) the received services from said Femto base station (3) so that said mobile terminal (2) can receive the relayed services when it is in the second specific mode.
