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.
