Hello I need advice from ANR experts:
In my network we use ANR in LTE, but I have found that the behavior is quite strange, some time the enodeb has neighbor relation with sites that are very far for the mobile to be able to perform a handover, so which is the policy inside ANR to add that neighbor?, I have red somewhere that it is based in the measurements taken from the mobiles but it can be because some sites are more than 20km far from the serving cell.
Is there any relation between the enodeb IP and the way ANR add neighbor??, if the enodeb and the neighbour are in the same subnet for example..
Also Many times I found that there are many X2 link interface alarms, but if I delete the X2 faulty link interface it will be automatically created again and it will became faulty again.
If I delete all X2 interfaces in a enodeb will the handover work automatically via the S1 interface or should I have to perform some manual commands??
How can I modify the way ANR manage the neighbor cells??
How can I reduce the ammount of neighbor cells??
