High SDCCH Fail/drop during night

[saidou]

Dears, I'm facing an issue that some cells are having high SDCCH fail and drop and even call drop but during night between 23H till 06H where the traffic is very low, did any one face this issue before.

Thanks

Dear Saidou,

We also faced this issue but after analysis we came to know that other operator attempts are more during this time.

I mean to say when other operator tries to attempt they we will not allow them to latch so at that time it keeps on attempting number of times so this value increases during late night as u told

Tkx for your response,
Can you give us more explanation?
What's you mean by "other operator attempts"?

I think this is related to TXN subject due to fading problems.

Check the node side backbone and cilink and cbadframs counters.
