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: A method for attaching a user terminal to a base station of a network is disclosed, said network comprising base stations. The method including defining a global cost function which is a weighted sum of the user terminal transmission delays, over all the user terminals in the network, using a user terminal's context weighting factor representing a user terminal's characteristic; defining a local cost function for each user terminal from said global cost function, said local cost function taking into account said user terminal's context weighting factor for each user terminal, and being a function of the base station to which this user terminal is associated; running a Gibbs sampler with said local cost function for producing user-base station association probabilities; choosing the user-base station association probability which favors low local cost; and attaching said user terminal to a base station according to the user-base station association probability chosen.

Abstract: Embodiments of the invention relate to a method to authenticate a user equipment in a wireless network using a smart card (11) comprising at least one credential token (13, 15), wherein the smart card (11) is accredited by a primary authentication authority (3) and installed in a user equipment, comprising: transferring a first credential token (15, 17) of the smart card (11) installed in the user equipment to a selected first mobile network operator (9, 13), using the first credential token (15, 17) to authenticate the user equipment on the mobile network of the selected mobile network operator (9, 13). Embodiments of the invention also relate to the associated smart card.

Abstract: In a communication system, a plurality of communication entities can establish a plurality of communication links that can potentially interfere with each other. A control of the communication system involves repetitively carrying out a probabilistic parameter setting step for respective communication links. In such a probabilistic parameter setting step, a parameter setting to be applied to a communication link is randomly determined according to a probability distribution. This probability distribution is such that a probability that a particular parameter setting is applied decreases with, on the one hand, a relative level of interference that the communication link is expected to experience from other communication links if the particular parameter setting is applied and, on the other hand, a relative level of interference that other communication links are expected to experience if the particular parameter setting is applied.
