I agree, we have been after this for a long time now. With the flat terrain here, it is very possible for a UE to end up on the wrong tower causing customer complaints. PCI lock would be ok, but the current UE software also requires earfcn which ties your hands to making any frequency changes.

Yes…that is the case….The 1000’s are in the same situation right now in regards to handoff….Telrad can correct me if I’m wrong. We pressed Telrad for HO because we did not want to do PCI or earfcn locks…especially if I add new sites and need to adjust my RNP (Radio Network Plan).

We are currently on a BETA enodeB build with Handover enabled. I have not verified in the field yet but the tech at Telrad has told me that it is doing what it is supposed to do on 3 smaller towers. We are using 2.3Ghz and we are having Ducting issues with AT&T (They use FDD)…the FDD uplink channel is 2355@10Mhz…so during Ducting some of our tower users at 2355Mhz get pushed to sectors running 2310Mhz but never return to their original sectors…the HO should solve this. Once we are satisfied and roll it our on the entire network I can certainly let you all know. The new build enables the X2 interface which is necessary for successful HO.

Hey Jeremy, We are seeing the same issue here. I talked to David @ Telrad about setting up the handover. He said it was not currently setup to work the way we would want and would more then likely cause UE's to ping/pong back and forth between eNBs. I have not tried it, but I would think that if handover was set to move UE's with CINR <=5 then it would force those UE's to move to a better eNB. That might leave some UE's with CINR of 6-10 that would need to move but would not. If the handover threshold works up to ~15 CINR (just to try to get all of them) then UE's might ping/pong back and forth between eNB's. You might end up with a hand full of UE's that need to move but don't hit the handover threshold. Need more details from Telrad on how that works -- all assumptions on my part.

I'm seeing a situation on a 360° site where if we take one ENB down (say, a config change), UEs on the edge can easily associate with the "wrong" ENB. The UEs stay on the wrong ENB even when the stronger signal comes back online. We aren't currently using frequency lock. Theoretically the handover thresholds can be manipulated (RSRP) to allow the UEs to migrate back to the "right" ENB, once it comes back online, correct? Or is the only working approach right now to lock each UE to a specific frequency?
