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.

Abstract: Communication systems may benefit from various aspects of emergency call handing. For example, wireless communication systems may benefit from clean up with respect to a fast return feature applied to an emergency call using circuit switched fallback, without a location area update. A method may include identifying an emergency communication that is a circuit switched fallback communication of a user equipment. The method may also include configuring communications so that mobile terminated services work properly after completion of the emergency communication. More particularly, for example, a method may include determining in a network element that the emergency communication is a circuit switched fallback communication. The method may also include, when the emergency call is ended, avoiding invoking a fast return feature for the user equipment.

For example, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include providing a network identification corresponding to the source network while requesting the handover. Alternatively, or in addition, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include determining the target network based on a network identification received previously.

Abstract: Methods and apparatuses for SMS delivery between user equipment without MSISDN is provided. One method includes sending a SIP message, which may include an SMS payload, to the IMS network where the destination UE is homed, and determining whether the destination UE is IMS registered.
