LTE: UE request to other network.

[TOPXP]

Dear all.

After rehome eNobe Nokia from MME Erison to MME Nokia, my network have alot of HO prepair fail. My eNodeB send a lot of HO request to other network (even network in other country). So there alot of HO prepare fail via S1. Do you know any parameter in MME to deny this case.

My eNodeB have Automatic Neighbour Relation (ANR).

Thanks.

I attached some log from MME. (WireShack)

Hello,

It might happen at MME Boundaries if no pooling. Check in per NBR Stats which Neighbor relations are contributing.

It can be possible because of MME Pool configuration issue OR missing S1 Interfaces.
