LTE Handover

[lsiddd]

Is it possible to coordinate LTE handovers through the SDN controler? If not, does anyone know how it could be implemented?

Theoretically you can packet_in LTE control messages to the SDN controller. However, due to the fact that LTE handover has a strict requirement in terms of timing, handling those messages in SDN controller will be less efficient and thus less desired. Practically, I would suggest you explore programmable pipeline switches (such as P4) and see if you can offload some of the work to hardware.

I am carrying out some mobility experiments with LTE and I cannot configure handover between eNBs. I tried modifying source code of lte.py and introducing lteHelper.AddX2Interface() sentence, but it ends up in an error when X2-U udp socket is created on each eNB.
Any of you know how to implement LTE handover in OpenNet?
Thanks,
