Preparation Intra Freq in Ericsson is zero. Any ideas what the cause may be?

Preparation Intra Freq in Ericssonis zero.


These counters are zero. any idea?

first, Verify configuration of relations, PCI and TAC is correct? and Nbid of sites this relation

tac and NB is Ok

and PCI? PCI Conflict and Colision

There is no conflict

and Colision?

Its incoming HO what’s about out HO

Try disable ANR and delete all neighbors. After enable ANR.

@Cesar_Nunes
If these values are Zero it means No Rejection.
counters are related to “handover preparation failure “mainly License issue like “Connected users license capacity exceeded of target cells which OFFLOAD Traffic from Target cell.
Secondly,
Counter 5-6 are Related to highload or OverLoad… and admission rejection.
Hope above detail will help you.thanks

Q: Intrafreq Prep Failure.
A:Check other Kpi like Erab sr and Erab drop rate is ok ?
There is any TNL failure ?
Check counter of Tnl failures,Transport Network Link Failure due to Transmission.
Also check MME id is correct.

Check termpoint to mme defination. If it is diffrent for neighbors then also it may impact prep SR.

If it is intrasite intrafreq prep failure check for cell availbility fluctuation. If it is ok delete and recreate cell relation.
If it is intersite intrafreq check for same MME mapped with nbr and also check availability status. Need to check duplicacy of enb id in system if there are more than 1 vendor need to unique enbid.
Still pre failure cold reset for site.
