Lte serving cell ID

[Lucas Pacheco]

Hi, everyone!

In my simulation i have an LTE scenario and a modified version of the A2A4HandoverAlgorithm, is there a way, during algorithm the measurements to know the Id of the serving cell? It's giver its rsrq, but i must get its it. Couldn't find anything about it so far..

Thanks in advance.

I mean, in the a2-a4-rsrq-handover-algorithm.cc file.

Hi Lucas,

I think with the current implementation of handover algorithms you don't have access to source cell id. However, it should be accessible with simple modification. Look how a handover algorithm interact with an eNB through a SAP and then you can use that SAP primitive to get the cell id of the eNB.

Kind regards,

In the context of the simulation, more than one ENB-UE link may have the same rnti, right? If not, I was wondering if it could be used to track the id..

Handover algorithm is eNB specific and each UE attached to an eNB would have different RNTI. I didn't understand how would you track the serving cell id in a2-a4-rsrq-handover-algorithm.cc with just RNTI. There could be two solutions, one I already told you in my previous post and second would be to edit the UeMeasurementReport to include the serving cell id with every report.

If you find out the way other than what I proposed, please do share for future readers

Kind regards,

I'm gonna try those, thank you very much!
