Hi guys,
What can be the causes for the following situation:
SDCCH Seizure Requests: 17
Failed SDCCH Seizures due to Busy SDCCH: 23
Failure is more than request. Vendor is Huawei, BSC6000. It happens in all cells of the site. So consequently
Congestion Ratio on SDCCH per CELL (due to Busy) = 140 %, 170 %….
No any alarm
During drive test no any block call
All frequencies were changed
Software of BTS was updated
Site was deleted and re-created in the BSC
Site was restarted
but…no any lucky result. SDCCH Congestion still is more than 100 %.
Please your comments.
