Title
(EN) COMMUNICATION TERMINAL AND METHOD FOR ESTABLISHING A COMMUNICATION SESSION
(FR) TERMINAL DE COMMUNICATION, ET PROCÉDÉ D'ÉTABLISSEMENT D'UNE SESSION DE COMMUNICATION
Abstract
(EN)
According to one embodiment, a communication terminal is described comprising a registration circuit configured to register the communication terminal with a first mobile communication system core network, a determination circuit configured to determine whether to establish a communication session via the first mobile communication system core network or via a second mobile communication system core network and a session establishment circuit configured to, if the determiner has determined to establish the communication session via the second mobile communication system core network, establish the communication session via the second mobile communication system core network wherein the registration circuit is configured to keep the registration of the communication terminal with the first mobile communication system core network.
(FR)
Un mode de réalisation de l'invention concerne un terminal de communication comprenant : un circuit d'enregistrement configuré pour enregistrer le terminal de communication sur un premier réseau central de système de communications mobiles ; un circuit de détermination configuré pour déterminer s'il faut établir une session de communication via le premier réseau central de système de communications mobiles ou via un second réseau central de système de communications mobiles ; et un circuit d'établissement de session configuré pour, si le dispositif de détermination a déterminé qu’il fallait établir la session de communication via le second réseau central de système de communications mobiles, établir la session de communication via le second réseau central de système de communications mobiles, le circuit d'enregistrement étant configuré pour maintenir l'enregistrement du terminal de communication sur le premier réseau central de système de communications mobiles.
