srsUE can not attach to eNB #727

Closed fancyshirt closed 3 years ago

fancyshirt commented 3 years ago

Issue Description

[srsUE keeps searching eNB but can not attach to eNB]

Setup Details

[Specify details of the test setup. This would help us reproduce the problem reliably] Machine-1: Ubuntu 18.04 Running srsepc amd srsenb UHD 3.15 installed Connects to a USRP N310 with UHD 3.15

Machine-2: Ubuntu 18.04 Running srsue UHD 3.15 installed Connects to a USRP N310 with UHD 3.15

Expected Behavior

After EPC and eNB are already running, UE can attach to eNB.

Actual Behaviour

srsUE keeps searching for attaching. root@machine2:~# srsue --rf.device_args=send_frame_size=1476,recv_frame_size=1476 --rat.eutra.dl_freq=2560e6 --rat.eu tra.ul_freq=2680e6 Reading configuration file /root/.config/srsran/ue.conf...

andrepuschmann commented 3 years ago

The N310, or the UHD drivers, are a bit picky and so there are still issues with it. We're trying to address them and also flagged them with Ettus, see (though this is with UHD 4.1):

This is a bit better on the eNB with UHD 3.15 and the N310, but the UE, as far I as I can tell also there requires special parameters to avoid retuning. Check the NSA appnote here and try the srate= param.

fancyshirt commented 3 years ago

Thank you @andrepuschmann . I will go through the NSA appnote you gave and see if any of those solve the issue.

fancyshirt commented 3 years ago

@andrepuschmann I'm connecting USRP N310 to my host over a 1GigE cable. Is it required to connect them over 10GigE or 1GigE should able to work as well?

@andrepuschmann I'm connecting USRP N310 to my host over a 1GigE cable. Is it required to connect them over 10GigE or 1GigE should able to work as well?

Depends on your particular cell configuration. Check the bandwidth requirments, but for a typical 10Mhz cell in SISO the 1GigE should be enough.

@andrepuschmann I'm trying to figure everything out, so I read through the log file from enb.log. The log is shown as follow enb.log

It keeps saying Underflow or Late. Also my terminal shows the following message:

On the N310 you have to use the LTE sample rates. E.g. --exper.lte_sample_rates=true or similar.

bondadakumarsai commented 3 years ago

Ran the srsRAN (release_20_10) with UHD 4.1.0.4 version installed. Initially, the srsENB & srsUE were able to recognize the N310s but srsUE. couldn't attach to srsENB. The steps I followed to make it work

  1. Set CPU to Performance mode
  2. Change LTE sample rates to ON in the CMakeLists.txt file
  3. What I found in the srsUE code (main.cc) was use_standard_lte_rates was set to false permanently, cannot be configured in ue.conf file. Changed the state to true. Added lte_sample_rates=true in enb.conf file
  4. Then built the srsRAN code and ran srsEPC, srsENB & srsUE. I was able to see UE being attached to Cell and was able to ping traffic.

Thanks for the feedback.

What I found in the srsUE code (main.cc) was use_standard_lte_rates was set to false permanently, cannot be configured in ue.conf file. Changed the state to true. Added lte_sample_rates=true in enb.conf file

That is only the default. You can overwrite it with --expert.lte_sample_rates=true

Anyway, closing the issue as I think it's solved. Also no feedback from the original author.

Setup Details

[Specify details of the test setup. This would help us reproduce the problem reliably] e.g. Network configuration, Operation System, Hardware, RF front-end, library and driver versions

Expected Behavior

[UE should be attached with eNB, as from core side IP been allocating from SPGW after

Getting error -> Cause #16 – MSC temporarily not reachable

  This EMM cause is sent to the UE if it requests a combined EPS attach or tracking area updating in a PLMN where the MSC is temporarily not reachable via the EPS part of the network.

Cause #17 – Network failure

  This EMM cause is sent to the UE if the MME cannot service an UE generated request because of PLMN failures.

Cause #66 – Requested APN not supported in current RAT and PLMN combination

  This ESM cause is used by the network to indicate that the procedure requested by the UE was rejected as the requested APN is not supported in the current RAT and PLMN.
