Abstract:
Creation or update of a security context between user equipment and MSC/VLR (Mobile Switching Centre/Visitor Location Register) for circuit switched domain services is provided. The creation or update is based on conversion of the security context used in an evolved Universal Terrestrial Radio Access Network (E-UTRAN) in the Mobility Management Entity (MME) to a security context for the circuit switched domain target system and transferring it to a MSC/VLR. When user equipment is moved from E-UTRAN to GSM EDGE Radio Access Network/Universal Terrestrial Radio Access Network (GERAN/UTRAN), a MME does not need to perform authentication and key agreement procedures to establish shared circuit switched security context for the user equipment.

Claim (Index 29):
A non-transitory computer-readable medium storing computer-executable code for creation or update of a security context, comprising code to:\n transmit, from a user equipment (UE) to a first network, a combined registration request for combined registration of services of the first network and services of a second network; transmit a request, from the UE to the first network, to create or update a security context of the second network maintained by the first network in connection with the combined registration and before the UE moves to the second network; receive an indication at the UE to derive the security context for the second network; and map a current packet-switched (PS) security context of the first network into the security context of the second network.
