Hi,
I am trying to implement a slicing scenario as follows.
I am using open5gs docker image, oran-sc-ric, one gnb and 3 UEs. UEs have been configured for slicing as follows:

[slicing]
enable = true
nssai-sst = 1
nssai-sd = 1

gnb is also configured as follows:

  dl_arfcn: 368500                  # ARFCN of the downlink carrier (center frequency).
  band: 3                           # The NR band.
  channel_bandwidth_MHz: 10         # Bandwith in MHz. Number of PRBs will be automatically derived.
  common_scs: 15                    # Subcarrier spacing in kHz used for data.
  plmn: "00101"                     # PLMN broadcasted by the gNB.
  tac: 7                            # Tracking area code (needs to match the core configuration).
  pdcch:
    common:
      ss0_index: 0                  # Set search space zero index to match srsUE capabilities
      coreset0_index: 6             # Set search CORESET Zero index to match srsUE capabilities
    dedicated:
      ss2_type: common              # Search Space type, has to be set to common
      dci_format_0_1_and_1_1: false # Set correct DCI format (fallback)
  prach:
    prach_config_index: 1           # Sets PRACH config to match what is expected by srsUE
    total_nof_ra_preambles: 64      # Sets number of available PRACH preambles
    nof_ssb_per_ro: 1               # Sets the number of SSBs per RACH occasion.
    nof_cb_preambles_per_ssb: 64    # Sets the number of contention based preambles per SSB.
  slicing:
  -
    sst: 1
    sd: 0x000001
  -
    sst: 2
    sd: 0x000042

The UEs have been set up in the "subscriber_db.csv" for the open5gs core to accept them.
I start the core and go to the webui to configure the sst and sd of UEs. After that I would start the system as mentioned in this tutorial.
Without slicing the system works perfectly fine, but applying these changes, the core disconnect the UEs.
The core output:

Can you please help me solve the slicing issue?

There was a problem with the csv file apparently. Installing everything from scratch solved the problem.

You may want to apply this patch to srsUE - srsran/srsRAN_4G#1214

I deleted the lines based on this.
I completely rebuild the srsRAN_4G project and here is the output I get from the open5gs core:

It seems like now the core is looking for NSSAI.
Is there anything else I needed to change?

Can you please verify whether the slicing parameters are still configured in srsUE? because I see in 5GC logs the following

open5gs_5gc  | 10/17 14:02:07.113: [gmm] ERROR: Cannot find Requested NSSAI [1] (../src/amf/gmm-handler.c:417)

Basically, UE is requesting S-NSSAI with SST 1 (no SD)

Btw, always please upload NGAP pcap for better debugging

I did check config file of UEs. Here is the UE1 config:
ue1_zmq (copy).txt
And here is the gNB NGAP pcap file (I changed the extension to txt):
gnb_ngap (copy).txt

Here is the output I get from the open5gs core also containing the changes that happened to the database when I change UE config using the webgui:

As far as the open5gs core, I didn't change any configuration other than the "subscriber_db.csv" and I am using the docker image that srsRAN_Project provides.

@alirezalab134 please make sure the "subscriber_db.csv" is used. Make sure its filename is set here instead of the example string

-SUBSCRIBER_DB=001010123456780,00112233445566778899aabbccddeeff,opc,63bfa50ee6523365ff14c1f45f88737d,8000,9,10.45.1.2

@alirezalab134 any update on this issue?

There was a problem with the csv file apparently. Installing everything from scratch solved the problem.

Hi @alirezalab134

I'm trying to implement slicing in my ZMQ multiUE srsRAN scenario (same as you) but I got the same error that you mention. I have followed the steps related in this post but i still have the issue. Can you share your configuration files to replicate them?

Thanks

@jjose001 you might try to follow this post: #642 (reply in thread)

jjose001 Dec 13, 2024

Hi,
Thank you @pgawlowicz. After checking #642, I could manage different slices and understand much better how to configure this capability in my structure.

Thanks
