    摘要: The invention relates to a method and arrangement in a serving Radio Network Controller, SRNC for controlling inter RAT handover to E-UTRAN of a UE with E-UTRA capability operating in a serving network comprising said SRNC, wherein the SRNC receives, from a Serving GPRS Support Node, SGSN, security keys generated at authentication and key agreement, AKA, upon attachment of the UE to the serving network; characterized in the steps of —determining (202) which type of UICC the UE is equipped with by analyzing the security keys received from SGSN; —using the knowledge of which type of UICC the UE is equipped with to base a decision (204) on whether to allow handover of the UE to E-UTRAN.

    摘要: User Equipment (UE) receiving non-voice packet switched service in an Evolved Universal Mobile Telecommunications System Terrestial Radio Access Network (eUTRAN) cell undergoes handover to a circuit switched GSM/Edge Radio Access Network (GERAN)/UTRAN cell in response to a requirement for voice service. The voice service is established in the circuit switched domain of a GERAN/UTRAN cell to ensure service continuity regardless of UE mobility that would otherwise not be possible if the voice service was established in the eUTRAN cell. A Gs-like interface between a Mobile Switching Center (MSC) of the CS Core Network and the Mobility Management Entity (MME) of the Evolved Packet Core provides an interface for page requests and location update procedures to be performed.
