Can anyone please tell me what can be the possible cause for when a network initiated USSD request is followed by a release message from the network.

For example, network (MSC/HLR/VLR) sends a USSD request to the MS. Before the MSC can send MAP OPEN RSP to the HLR, the it receives RELEASE COMPLETE message from BSS.

Now, what can be the possible cause and solution for above problem. Please note that, the issue is being faced in Huawei Core & BSS network. The problem occurs randomly and not for all the calls e-g issue is observed with 1 call out of 10 calls.
