Hi Expert,
I am encountering the numbers of failure issues of voice Call (MO CS Call Dropped) for the drive test of CS with the cause as follows:
Drop_Cause_WCDMA : CCCH RRC Release (directed signalling connection re-establishment), no NAS release
Anyone could advise on the possible cause of this issue,
Many Thanks in Advance
