    Hello everybody,

    we have a problem with outgoing calls directed from subscribers registered in UMTS to CAMEL subscribers.

    This problem has appeared after changing of support XUDT messages between MSC(UMTS) and MSC(GSM).

    Without XUDT there is impossible handover from UMTS to GSM. Vendor Ericsson.

    Any suggestions?

    1. What’s the scenario of call: UMTS -> GSM CAMEL subscriber?
    2. Does GSM MSC support XUDT ?
    3. Does called CAMEL subscriber have T-CSI subscribtion?
    4. Does IDP (on call-termination) fit in one XUDT?

    Hi!
    U can use xUDT to handvover between 3G to 2G and setting redirect Handover over GMSC instead of STP to LongMeassage so all operations in systems run normally.

    BRs!

    Hi Community,

    Answers to different questions in this thread.

    XUDT – SCCP Extended Unitdata Message. Similar to SAR (segmentation / Re-assembly) with TCP/IP.

    UMTS (3G) – GSM CAMEL. This can be used for Telephony Prepaid services. The HPLMN and the
    VPLMN will need to support, as a minimum, CAP V2 and MAP V3.

    CAMEL supports various flags that are known as x-CSI (CAMEL Subscription Identity). Typical, flags are
    Originating (O) – CSI, Terminating (T) – CSI, etc..

    GSM MSCs suppprts SCCP, therefore, XUDT should be supported.
