Sync up between subscriber module and gnb module

[pragnyakiri]

Hi,

I am loading the subscriber module and adding 3 users. When I type "user list", I get a list of 3 users that I added. I exit the module.
Then I load gnb module, When I type "user list" here, it doesn't return anything.
It is not showing any users in gnb module.

Am I missing something here ? Aren't subscriber and gnb modules synced up with each other ?

Thank you.

In fact, gNB module is not returning any list. (Attached screenshot)

What am I doing wrong ?

Hi @pragnyakiri,

The user equipment is registering on the network but no PDU session seems to je established.

Can you please indicate me the following informations:

• OS Version
• Golang Version

Also, can you paste CN AMF, SMF, UPF, NRF, AUSF log files please to check wether the procedures were triggered on the CN.

The modules are not sync, usually I launch 2 different instances of free5gc-cli, one to manage the subscriber on the same host than the CN and another in the gNB VM with UE as docker host. This however could be a feature to add in the future.

Thanks

Hi @Srajdax,

OS version : Ubuntu 20.04.1 LTS
Golang version: go version go1.14.4 linux/amd64

Below is the log I get on the console, when I try to register a new user from gnb module.

So the request of registering a new user is reaching the core network, isn't it ?

Thanks,

The output does not show that the user is registered on the network,

Maybe check that you are reaching the correct CN and try the following fix:

Flush the free5gc mongo database using the database module. After that restart your 5G CN, load the user into the DB and start the gNB module.
