In one embodiment, a scheme is provided for managing secure registration of a mobile communications device. Upon being provided with an upgraded registration process that requires encryption, the mobile communications device has the option of continuing to register with a network node using a downgraded registration process within a specified time window which involves unencrypted registration requests and responses. Thereafter, the mobile communications device is operable to select between the upgraded and downgraded registration processes.
Selon un mode de réalisation, un mécanisme est prévu pour gérer l'inscription sécurisée d'un dispositif de communication mobile. Après réception d'un procédé d'inscription amélioré nécessitant un cryptage, le dispositif de communication mobile peut continuer son inscription avec un noeud de réseau en utilisant un procédé d'inscription déclassé dans une fenêtre de temps précise ne nécessitant pas de cryptage des demandes et des réponses relatives à l'inscription. Par la suite, le dispositif de communication mobile peut fonctionner pour sélectionner les procédés d'inscription amélioré et déclassé.
