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 %.

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?

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

How is iRAT HOSR 4G to 3G KPI?

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.
