Reply To: handover failure due to protocol error


Hello Ali/Pix/Rex,

Thanks for all your suggestions. But we are loosing the track of the issue on this forum.

Coming back to the issue, i have checked and found no issue with HO definations in database. HO failures are too irregular in nature. This issue is observed in intra cells HO as well.

Getting this error msg in DT log.

*** Layer 3 Message type: Handover Failure

Protocol discriminator : (6) Radio resources management messages

Value : (111) Protocol error, unspecified

Any guy ever come across such error?????

As of now i am check the clock sync status and whether it is calibrated or not for problematic BTS’s.

Rex…if i found clk sync OK then i will try to change SUM board of one the BTS and check.
