I am testing the handover functionality on S1 with 2 eNB of the
OpenAirInterface implementation, both transmitting on the same frequency
and with the same TAC.
The way I do it is ass follows:
- I start the EPC.
- I start one of the eNBs.
- I connect the UE to the network.
- I start the second eNB.
- I move the UE away from the first eNB as I move it closer to the
By following these steps, instead of the handover taking place, what
happens is that the second eNB stops, showing an error, and the UE remains
connected to the first eNB. Here is the error of the second eNB:
And in the interface S1 there is no message related to the handover.
I wonder if I am doing something wrong or if this functionality is not
available with the OpenAirInterface eNBs or something like that. I attach
my configuration files and the log of the mme.
I am not sure if the reason for this failure is the NextEPC core or the
eNBs, because I have tried the same EPC configuration with srsENBs and the
messages in the S1 interface are the same.

Hello Guys and thanks a lot for a great product.
Have a question which I couldn't find in documentation.
Is it possible to use two separate PGWs with NextEPC? Each PGW represents a different network (i.e one for Internet, another for some kind of LAN). I also would like to add two different APNs per UI in this scenario. I have already done a singe PGW configuration with default 'internet' APN, but stuck a bit with the second PGW.
I will highly appreciate for any thoughts, advise or configuration examples.
Thanks in advance.
