Slicing problem

[AlejandraOliver]

Hi everyone!

I follow the steps @pgawlowicz mentioned in #642 but I have this issue in the open5gs when the gbn tries to connect:

Below I show you the configuration I have:
config (2).zip

---

Maybe the problem is because open5gs-5gc-yml is using add_users.py and this script is only configured with one UE? I dont know...

I want to have 2 UEs, each of them in one slice.

(without slicing the network works perfectly,
I´m running all in a VM, also lastest version of srsrRAN Proyect ).

(I saw #642 but don`t solve my problem:(

If you could help me!! Thanks!!

I had the same problem but after modifying add_user.py the UE was able to attach with sst and sd specified. The content in slice_data has an extra line under sst "sd": '000001', which allows sd to be passed to the user db. I think in your case you need to make imsi specific slice_data to use different sst / sd across users.
