hello i want to know weather can UERANSIM can be connected to srslte core.

after sucesssful registration pdu session management failed. i have using UERANSIM-master is it the latest version

Hello.

I have plan that construct 5G environment using UERANSIM.
So.. I have one question about UERANSIM.

The UERANSIM is support the SDR(such as USRP)?
I have USRP X300 and will using for 5G environment.

If you can reply this question, please.

Thanks.

Hi,

I installed Open5GS v2.1.1 and UERANSIM v2.2.1 on the same VM. I successfully established PDU connection, but getting [ERRO] [UEAPP] [ue-901700000000003] Ping timeout for google.com (172.217.24.14) after 3 sec no response.
Here is my log:

I want to inform the community that User Plane functionalities are ready to use.

We are introducing the TUN interface in order to use UE's internet connectivity. This feature can be considered as beta and usage method is subject to change, but I think the feature seems more or less stable. And as always we are open to feedbacks, bug reports, pull requests etc.

In our tests, we have successfully browsed the internet using 3 different core networks. (Open5GS and 2 other commercial CNs)

You may want to try this feature for yourself. Related documentation can be found at: Using Data Plane Features

For your information, currently we only support IPv4 protocol. Other PDU types are in road map and not implemented yet.

Hey @aligungr I tried you're latest v1.0.9 release and got the following Java exception when trying to establish a PDU session:

I am still using free5gc and it seems to happen for each UE.

hello i have sucesfully setup open5gs with UERANSIM now i want to see the authenication data in wireshark but i can see nothing related to registration and authenication in WIRESHARK . plzz help

In the latest version of Open5GS and UERANSIM, when I run NG-Setup / Registration / PDU session establishment when ignoreStreamIds=false/true and checked pcap files, these packets look like the same SID's sequences as below.

Is it generally desirable to set ignoreStreamIds=false? Or true?

Sorry if I misunderstand.

Hello,
Is it possible to generate an encrypted Suci instead of using "Null-Scheme" for Suci generation?
Or is it planned?
Thanks for your support.

Hi
As I checked history version of 1.1.0 it was mentioned "RRC encoding implementation".
I want to ask how This feature can be tested? Can I see the packets in wireshark?

Thank you

Hi UERANSIM team,
We met a problem when we use the config "free5gc"
Have you met the problem about the below error?

Hi @aligungr

It would be very helpful if the IP address assigned to the UE's TUN interface from the core network is automatically set to the UE's TUN interface.

I'm sorry for many requests.

hello i want to know whether the UERANSIM can be connected to multiple core network simultaneously. i want to perform the slicing of the network where each core networking serving differenet purpose

Hi,

I'm trying to connect UERANSIM to open5gs and I'm having some trouble with the gNB-AMF/N2 connection.
The connection cannot be constructed and the run-script then times out. I can affirm that the IP address and port number is correct and the packets arrive on the other side (using tshark). The request is a INIT, the AMF replies with a INIT_ACK but then UERANSIM (or the Ubuntu where it runs on) sends an ABORT. I've looked into the source code and it seems like the connection is handled by com.sun.nio.sctp.SctpChannel. I cannot find any documentation on why the Aborts are sent.

Does anyone know why an ABORT could be sent over SCTP before even a successfull connection? If I change the port of the AMF in UERANSIM without changing the actual port in open5gs, no INIT_ACK is sent, but a ABORT is replied (by the AMF-host). The ports and the AMF must thus be correctly set up. The AMF does not even show a log entry at all (which is strange).

Did anyone have similar issues? Is this maybe even a bug in one of the systems?

Thanks a lot!

hello, i have a query regarding the initial registration request sent by the UE to gnb. in wireshark i am able to see the registration request which is sent from gnb to AMF but unable to see the registration request sent from UE to gnb . is it not implemented?

hello while running the new update of UERANSIM i am getting error "UE context could not found in receiveRrcMessage" . i have checked the configuration on both side ie . CORE and gnb both are same.

Hello @aligungr,

The cli function is awesome, I can write the customize testing script as need.
But I tried to run UERANSIM@master with [email protected], it has some issue when sending UE RegistrationRequest.

The current version of UERANSIM sends the RegistrationComplete message to AMF, and as the following definition in 3GPP TS 24.502 4.2.2.2, if AMF receives the RegistrationComplete message, and PDUSessionList wasn't include in RegistrationRequest, AMF will send UEContextReleaseCommand to UE, so the connection breaks and UE can't establish the PDU session.

Compare to the previous version of UERANSIM(7c89a4b), it was able to work with free5GC, and its UE doesn't send RegistrationComplete message.

Could you please help me to solve this issue?

Thanks.

previously i was able to ping the google but now suddenly i am getting the error [ERROR] [UE_APP] [ue-imsi-901700000000003] Ping timeout for google.com (172.217.163.142) after 3 sec no response. plzz help

@aligungr i have sucessfully connected my open5gs with UERANSIM but unable to see any authenication or UE connect update in wireshark plzz help

Hi,
I'm using the lastest version of Free5GC (in docker). I'm getting an error while performing initial-registration. I'm using the default configurations in free5GC. The user is already added via webui.

Hi ,

When I compile the ASN files at step 4.8, it failed with below issue. Could you let me know how to fix it?

Error SystemError : File /tmp/asn16229926315433191916.xml not found. Check that /home/lnatrung/ue-ran-sim/ASNSDK-TCE-JAVA-COMP-PC-LINUX-BIN64/Compiler/bin/asnp is executable. Line 0 Column 0

Thanks,
Trung.

Hi, Actually this is continuation of issue (https://github.com/aligungr/UERANSIM/issues/98)
I have configured SCTP protocol in my linux kernal 4.18.0-147.el8.x86_64.
[dev@robi-app ~]$ checksctp
SCTP supported....

Now i am trying to run (./run) getting connection refused error. please find the attachment.
Is any configuration need to do?

After checking issue 180, there is still no solution, so what's wrong with me？Thank you.

Hey,
Thanks a lot for sharing this project!

I tried to test splitted solution, where UERANSIM installed on different VM than 5GC. In my case, I'm using free5gc in K8S and I'm using diffrent network interfaces to connect to AMF and UPF. Configuration of UERANSIM only supports to configure one host for N1 and N3 interfaces afaik, therefore, in my case, the same inteface which was used to connect to AMF for signaling part, trying to open GTPU to UPF on N3 interface and fail. Is it any option to define to UERANSIM to use other ip address for GTPuIF ? Is it may be in your planning/roadmap? Thanks in advance

Hello there,

I'm using UeRanSim v1.0.9 but I think the issue still exists in the latest branch.

The configuration file gnb.yaml shows two parameters :

gnbId: 1

nci: '0000000050'

If I am not wrong, they describe respectively the gNB ID and the NR Cell Identiy but in my opinion, they can't be independent because the 3gpp TS 38.413 - 15.2.0 - [9.3.1.6 & 9.3.1.7] says :

gNB ID - BIT STRING (SIZE(22..32)) - Equal to the leftmost bits of the NR Cell Identity IE contained in the NR CGI IE of each cell served by the gNB.

NR Cell Identity - BIT STRING (SIZE(36)) - The leftmost bits of the NR Cell Identity IE correspond to the gNB ID (defined in subclause 9.3.1.6).

In other words, the nci carries the gnbId so that, they can't be independent.

In my example, I set voluntarily two values that make no sense and the result is :

1. In the NGSetupRequest message, there is no NR CGI IE but only the GlobalRANNodeID that owns the gNB_ID (1 in my example)
2. In the next message, InitialUEMessage (NAS RegistrationRequest) there is no GlobalRANNodeID IE but the NR CGI IE that owns the NR Cell Id (5 in my example). That means the gNB ID == 0 and the CellId == 5 and this is wrong (assuming the gNB_ID is coded on 32 bits).

NOTE : The nci in the gnb.yaml file is really mysterious. Why did you used a 'xxxxxxx' value instead of an hex representation, like the nssais/sst for example ?

The difficulty is the gNB_ID size is variable.

My proposal would be :

Set the nci parameter (in the gnb.yaml) in an hex format and set the width of the gNbId in number of bits like :

# gNbId size is 32 bits
gNbIdSize: 32

# nci size is always 36 bits
nci: '0x5a'

So that the values are :
gNbId == 5
CellId == 10

Let me know if I missed something

EDIT: Merry Xmas @ALL

hello i have a query regarding the initial registration message which i got in the recent wireshark capture which is different from the usual wireshark capture . it consist of 5G-TMSI , UE Network capablity and lot of other various capabilities are also exposed that is never capture in before registration message there also i was able to capture service request and identity request which was not captured before . what can be the reason for it.

Now , I can establish PDU session with free5gc by UERANSIM. So, how to ping IPs like www.google.com use UERANSIM?

hello I am facing a error when I run the command session establishment . it says Unhandled message received: Pdu SessionEstablishmentRequest. can you please tell me How to correct the error

Hi
I am studying 5GC. In the documents it was mentioned there is a GTP tunnel between gNodeB and AMF and there is a GTP tunnel between UE and UPF. as I checked in Wireshark , there is no GTP tunnel between UERANSIM and 5GC(I am using open5GS)
I wonder how do I configure these tunnels in practice...
Would you please help me out?
Thank you

Hello every one
I'm new to ue-ran-sim and sorry for asking questions suddenly. I followed the guidance in https://github.com/aligungr/ue-ran-sim, but was stuck at the build process.
"All native libraries and Java source codes are compiled automatically on maven compile." I fell very confused with this sentence, how to use maven compile pom.xml?
Besides, can this project be able to simulate 5G RAN and UE?
Thanks for your help, best wishes.

I tried connecting UERANSIM(dev branch) to Open5GS.

initial-registration succeeded, but it continued, resulting in an error.

I used the default values of Open5GS WebUI for UE information. For IMSI that does not have a default value, I have set the following.

IMSI: 901700000000003

Also, the Stream ID of sctp was as follows.

i want to use multiple UE,when i created one more ue config file .registration got failed

Hello @aligungr, is UE-AMBR implemented? I have seen that the value received from the AMF is stored in the UE context, but then it is not used.
Thank you

hello while using UE tun interface i am encountering the following error Tun bridge routing failed, target not found for: 10.45.0.2. also my nas timer gets expired after ping message anyone can help to how correct these error

Linked issues: #160, free5gc/free5gc#142

I was using free5gc v3.0.4 and UERANSIM master branch recently, and I ran into the exactly same problem as @BraedenDiaz did, I checked this issue with the working pcap (testing with Spirent Landslide).

According to my guess, the issue comes with UEContextRequest wasn't included in IntialUEMessage, here is the comparison of "UERANSIM + free5gc (left)" and "Landslide + free5gc (right)".

In left side (UERANSIM + free5gc), InitialUEMessage didn't have UEContextRequst.

Therefore, free5gc will not set an important attribute uEContextRequest as true to the ranUe and amfUe instance.

When the ueContextRequest was set to true, free5gc will send the SendInitialContextSetupRequest when RegistrationAccept. Otherwise, it only send the DownlinkNasTransport message.

And here is the other important attribute called SentInitialContextSetupRequest, it will set to true when InitialContextSetupRequest was sent, this attribute was also determine whether free5gc sends PDUSessionResourceSetupRequest or InitialContextSetupRequest.

c.c. @aligungr @BraedenDiaz @free5gc-org

I am getting the same errors as mentioned in this issue #199 when I try to register a UE using UE RANSIM and Open5GS. Does anyone knows how to resolve it?

[ERRO] [PROC] [ue-901700000000003] Registration failed: DNN not supported or not subscribed in the slice

Hi @aligungr

Thank you very much for supporting U-Plane. It's great!

By the way, I want to communicate using the TUN interface, and even though I select 4) pdu-session-establishment, I could not find the TUN interface on the UERANSIM side.

I would be very glad if you could tell me how to use it.

Thank you very much in advance.

Hi @aligungr

I'm sorry if this question was the similar question as before.

Can multiple UERANSIMs run on the same machine? For example, specifying uesimtunX etc.
Is only uesimtun available as the TUN interface?

Thank you very much in advance.

hello experts i am using open5gs as core and UERANSIM as gnb . i want to connect my UE with UERAN gnb. i gave my subscription information in ue.yaml but it says authenication failed. can you tell me the procedure how to latch my ue with gnb

Hello,
I would like to know if the messages "AMF configuration update support" received after the "NGSetupResponse" are supported (if the UERANSIM is able to Acknowledge such kind of message)?

On running pdu-session-establishment with open5gs, registration is complete but pdu session is not established.

Hi,
I want to know the specific purpose of UERANSIM.
As I know,this simulator can register to open5gs and establish pdu session by execute run.sh then select 4.
But can the mechine which deploy UERANSIM ping the open5gs ogstun interface after pdu session established?

hello when i changed the tac value on both open5gs and ueransim to 2 it gave me error NGSetup procedure is failed: unknown-PLMN
.Is the ueransim is only compatible with only tac value of 1.?

under upgrade 2.01 how to add multiple UE as testing.yaml has been removed

I set imsi number @localhost:3000
this is subscriber configuration

Hi,

Initial-registration produces following error and gnb crashes:
There are no errors on AMF side.

All values for gnb and ue are default.

with value <208> this values changes. App log is also attached.
