APPARATUS AND METHOD FOR TRANSITIONING ENHANCED SECURITY CONTEXT FROM A UTRAN/GERAN-BASED SERVING NETWORK TO AN E-UTRAN-BASED SERVING NETWORK |
摘要 |
Disclosed is a method for transitioning an enhanced security context from a UTRAN/GERAN-based serving network to an E-UTRAN-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 a first enhanced security context root key associated with a UTRAN/GERAN-based serving network and a first information element. The remote station receives a first message from the E-UTRAN-based serving network. The first message signals to the remote station to generate a second enhanced security context root key for use with the E-UTRAN-based serving network. The remote station generates, in response to the first message, the second enhanced security context root key from the first enhanced security context root key using the s first and second session keys as inputs. The remote station protects wireless communications, on the E-UTRAN-based serving network, based on the second enhanced security context root key. |
