A lawful interception, LI, intercept access point, IAP, function (135) in a mobile connect, MC, identity gateway, ID GW, function (107) receives, from a LI administrative function, ADMF (108), a request for activation of LI for a target identity, A, during a specified LI time interval. A detection is made, during the LI time interval, that the ID GW function (107) has at least started an authentication and authorization procedure for a service that the target identity, A, has requested and as a consequence of the detection obtaining, from the ID GW function (107), personal data pertaining to the target identity, A, and providing the obtained personal data pertaining to the target identity, A, to a LI mediation and delivery 10 function MF/DF (132), for example via an X2 interface.

Selon l’invention, une fonction de point d'accès d'interception, IAP, d’interception légale, LI, (135) dans une fonction de passerelle d'identité, ID GW, de connexion mobile, MC, (107) reçoit, d’une fonction administrative LI, ADMF (108), une demande d'activation de LI pour une identité cible, A, pendant un intervalle de temps LI spécifié. Pendant l'intervalle de temps LI, il est détecté que la fonction d'ID GW (107) a au moins débuté une procédure d'authentification et d'autorisation pour un service que l'identité cible, A, a demandé et, en résultat de la détection, obtient, de la fonction d'ID GW (107), des données personnelles relatives à l'identité cible, A, et fournit les données personnelles obtenues relatives à l'identité cible, A, à une fonction de médiation et d'administration LI MF/DF (132), par exemple via une interface X2.
