Dear Experts.

Have you ever activated coverage based PS handover from 3G to 4G?

I tried it once, no much gain.

Service based is better.

Agreed.

And even within service based, both RSRP and RSRQ based can be switched ON.

I am wondering: when 3G UE start to measure LTE freq?

  • If UE measure too late, it will lose chance of handover & using 4G service.
  • If UE measure too soon, 3G compressed mode early make alot of interference.
