System and method for managing secure registration of a mobile communications device
摘要
In one embodiment, a scheme is provided for managing secure registration of a mobile communications device (116). Upon being provided with an upgraded registration process that requires encryption, the mobile communications device (116) has the option of continuing to register with a network node (216) using a downgraded registration process within a specified time window which involves unencrypted registration requests and responses. Thereafter, the mobile communications device (116) is operable to select between the upgraded and downgraded registration processes.
