Subject: Any major issues on master?
Message-ID: <20E2E96D-D419-4695-9BB2-8BF65FF38F84@cs.washington.edu>

Hi everyone,

I admin a couple of small-scale networks, one with ~20 users and one with ~100. They are basic, data-only LTE networks, and do not provide any voice services, 2g fallback, or interconnect at all. One has two eNBs and the other has one. We currently use the OAI EPC, but are very interested in moving over to NextEPC for reasons of stability. 

I?ve tested NextEPC in our lab (with only two phones and an SDR) and it seems to work great. I?ve looked through the code, implemented a feature or two, and it is much much  cleaner than OAI. I?ve also heard widely good reports of some other deployments.

Anything I should know, or any major issues I should be aware of before I go ahead and deploy the current master branch? I don?t mind finding/fixing a couple of bugs and will certainly commit any fixes upstream, just more asking about any already known fundamental problems, features unimplemented, or reasons I should postpone a rollout.

Thanks!
Spencer

Hi Spencer,

In the last few months I needed to make a lot of changes to this
project.I need to implement 5G core but I wanted to make sure that this
didn't affect the 4G source code much. As such, I changed BuildTool from
autotools to MESON and freeDiameter library is applied with new version
1,3,2. So, the project name is changed from NextEPC to Open5GS. These
things are almost finished today.

There are a few things left to do now, including implement GTP path
management before developing 5G core, which will not have a major impact on
the master branch.

Thanks a lot!

Best Regards,
     Sukchan

Subject: Regarding IP address assignment
Message-ID: <CA+N5aeUxm7efka6a3sLd+esktupEGFR9uYpZTCoe1WSn7tsK1w@mail.gmail.com>

Hi

In my project, I'm using IP address as 55.55.0.25/16 in nextepc.conf
My tunnel inet gets 55.55.0.25 , mask is 255.255.0.0
 IP address for my route from the pool is 55.55.0.1.
Why is this happening?

I want my route to start from 55.55.0.26 and so on...

how to do this? please help

Hi Murali,

Unfortunately, open5gs(nextepc) does not support the range of the ip pool.
As such, it is not possible at this time.

Let me paste the related source code regarding the issue.

Sorry for not being help this.

Best regards,
   Sukchan

Thank you for your response.  I'll try other way.

To add-on to this discussion, I do not believe that the subnet "
55.55.0.25/16" is valid. The entire point of the netmask (in this case 16)
is to denote the length of the network address in bits. A bitwise AND
operation should always provide the routing prefix, in this case 55.55.0.0.
A subnet with a non-zero value is only possible on orders of 2 and with an
appropriately long netmask, e.g. 55.55.0.128/25.

Hi

I'm using this project as a reference and it would be useful if i get any
document on this. It'll be really helpful.
