Intra cell handover recovery in huawei 2G

Hello guys.
I would appreciated if I know your comment about troubleshooting intra cell which means whitin cell handover.
Intra band hand over issues.

Specially in TA THreshold , TA histersis, and oss query

It would be better if you specify what kind of failure you are getting. TA based handovers are not primary optimization components usually. Usually handovers are optimized on Power Budget or receive level or Quality. So, if you specify the problem your are facing, it would me easier to answer

Imagine you faced hosr degradation related to intra cell degradation.

Which parameters you use.

No one knows?
