  • Integrity protection towards one CN after handovers involving multiple services to be handled by different CNs
    Publication number: 20140269613
    Abstract: A method includes receiving at a UE information indicating different CN domains will be used for first and second data services after handover from a first RAT to a second RAT. Integrity protection is activated for the first and second CN domains but an element in the UE does not have an indication integrity protection is activated for the second CN domain. The UE provides a notification for the element that integrity protection has been activated for the second CN domain. Another method includes receiving at a network node a message indicating a UE has performed a handover involving first and second data services from a first to a second RAT, where the first and second data services will be handled by different core network domains. A security mode control procedure is performed to activate integrity protection towards the second core network domain. Apparatus and program products are disclosed.
