RE: Somebody tried this (or parts of it)

by Holtmanns, Silke (Nokia - FI/Espoo)

Maybe it goes through this time. Seems it did not make it the first time... From: Holtmanns, Silke (Nokia - FI/Espoo) Sent: Friday, July 5, 2019 12:55 PM To: nextepc(a)lists.osmocom.org Cc: Kalliola, Aapo (Nokia - FI/Espoo) <aapo.kalliola(a)nokia-bell-labs.com> Subject: Somebody tried this (or parts of it) Hi, are mainly interested in the core network part and not on the UE part. What we want to do is have a PGW which has some the EPC "machinery" behind to get a TEID and have MME, HSS, SGW initialized and some not real UEs i.e. the fake UEs would sit in or next to the eNB. We do not need real internet connection for the "fake UE" and user plane is also not that important for us. Any hints? Greetings silke

Configuration of SGSAP

by Sukchan Lee

Hi, I need to implement SGsAP before I go to a CSFB. I have one question about the configuration. I gonna create a configuration of mme.conf as shown below. mme: sgsap: addr: 127.0.0.2 tai: plmn_id: mcc: 001 mnc: 01 tac: 4130 lai: plmn_id: mcc: 001 mnc: 01 lac: 43690 However, if both TAC and LAC are alway the same PLMN_ID, the configuration can be changed as follows: mme: sgsap: addr: 127.0.0.2 plmn_id: mcc: 001 mnc: 01 tac: 4130 lac: 43690 I don't have enough knowledge about 2G/3G, so I hesitate in this part for a while. Perhaps, I will do it the first way. Do you have anybody to help? P.S. You can see the full configuration in this like: https://github.com/open5gs/nextepc/blob/master/support/config/nextepc.conf.… Thanks a lot!

S1 handover failure

by Redes Comunicaciones Móviles

Hello! 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 second eNB. 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: [image: image] <https://user-images.githubusercontent.com/50883711/58153355-165e3e80-7c6f-1…> 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. Kind regards, Salvador. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Libre de virus. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Two APN/PGW per UI

by Liubinskii Pavel

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. BR, Pavel

How is IP address assigned

by Suman Bhunia

Hello! We just started using NextEPC at our lab and came across a few problems. I was wondering if anyone could provide me some guideline on how the EPC assigned IP address to the UEs. Any document or even pointing me to the correct section of code in the GitHub will be helpful. Thank you for your kind help. Thanks, Suman Bhunia Postdoctoral scholar Texas A&M University
