Abstract (en)
[origin: WO2011130684A1] Disclosed is a method for transitioning an enhanced security context from a UTRAN-based serving network to a GERAN-based serving network. In the method, the remote station the remote station generates first and second session keys, in accordance with the enhanced security context, using an enhanced security context root key and a first information element. The remote station receives a first message from the UTRAN-based serving network. The first message includes a second information element signaling to the remote station to generate third and fourth session keys for use with the GERAN-based serving network. The remote station generates, in response to the first message, the third and fourth session keys using the second information element and the first and second session keys. The remote station protects wireless communications, on the GERAN-based serving network, based on the third and fourth session keys.
