Experts:

What can be the reason for high handover interruption time between NR to NR HO?

Apart from poor radio condition any specific parameter to be checked?

In 5G SA.

2

Check path switch for N1.

Should happen fast.

Also check admission control on target gNodeB to happen without issue.

3

How do we check N1 patch switch?

In LTE there is a timer for S1 patch switch, but in 5G I need to find out.

System is Ericsson.

4

Usually a handover NR to NR should happen in less than 50 msec.

If it is more than this there are admission problems on target cell.

5

Why In Ericsson 5G SA Handover interruption time is High?

How can we Improve it?

Any parameters?

6

By adding packet (VoNR or data) along with HO command.

Thanks!

Can you explain with more details in Ericsson, if possible?
