    I am not able to understand this; while performing HO, why GSW is making unidirectional connection when MSC receives the HO request message?

    Only after receiving the HO detect / HO complete message it makes bidirectional connection.

    thanks

    hi all

    here is a strange case to me. i am trying to perform a inter MSC handover. both MSC are having different network. when the call is initiated in network-B , HO to network-A and subs-HO back to network-B is successful. but if the call is initiated in network-A, then handover to network B is not possible. MSC-B sends HO_DETECT and the MS sends an MS_ACCESS to new BTS , but after that it stays back with the old TCH seneind protocol error(ERROR-111).
    has anyone faces this kind of situation. please guide me.

    regards

    Hi alex you can use this commande to trace call path:

    Call Path Tracing, Initiate(CTRAI)

    for exemple
    CTRAI:MSISDN=5144774100;
    or

    CTRAI:IMSI=12652239;
    FOR MORE DETAIL REFAIRE TO alex library
