3G High PS/CS drop

TE 2 TM 0

I think that is necessary increases power UL more fast.

In CS don’t have problems - CS cal drop is < 1 %.

Maybe you can make te 3 or 4.

I suggest to decrease power and check result, may be it is indoor modem and ul is very low

Hi Experts.

I have an issue for the case of PS call drop in 3G.

I defined HO 3G to 4G for PS but the KPIs didn’t improve.

Anybody have any idea?

Network is Huawei 3G.

Do you see HO attempt from 3G to 4G?

Yes. And HO 3G to 4G is 98.7% successful.

So Core network support HO from 3G to 4G.

How is iRAT HOSR 4G to 3G KPI?

It is fine, 99%.

Only PS call drop in 3G is bad.

20%

whats the reason of Drop?

If it is noun coverage base handover/redirection toward LTE check [UCELLU2LTEHONCOV] Mo. There is several parameters related to triggering the procedure especially minimum RSCP on the 3G side.

Hi!
Please can you help witth parameters to check for Drop call issue ??? Vendor like you Huawei…
