Abstract
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.
