Unable to properly register the User in database for UERANSIM and Packetrusher to work.

[sandhyabagadi]

Dear @Borjis131,

I am trying to use your compose files for open5GS with UERANSIM and Packetrusher deployment.

Everything seems to work well, except the part when i try to add the user data to the database, the UE shows error.

This is the same even after i restart, also i did use the latest version of the open5gs-dbctl as mentioned by you in the issue number 8 reported similar issue

Please let me know if i need to test something or you need any further outputs from me to resolve!

Thankyou for your help in advance

Hi @sandhyabagadi, it would be useful if you post the UERANSIM gNB and Open5GS AMF logs too.

The only thing that I see is that seems that the registered UE does not have the sd value for the network slicing parameters.

Also the UE logs shown are telling you that the connectivity release is caused by the expiration of the T3511 timer.

Hello Brojis,

Thankyou for your response !

I tried it with webUI and mentioned the ST and SD values correctly, which made it work.

I still think adding with open5gs-dbctl will not add everything, it will just add the default values set by the script. I can give the logs if you are interested. I am okay if it is working through webui as well :)

Thankyou!!!

[Borjis131]

@sandhyabagadi if you were using open5gs-dbctl keep in mind that there is a couple of ways to add a user to the database.

Some of the options are:

add {imsi key opc}: adds a user to the database with default values
add {imsi ip key opc}: adds a user to the database with default values and a IPv4 address for the UE
static_ip {imsi ip4}: adds a static IP assignment to an already-existing user
add_ue_with_apn {imsi key opc apn}: adds a user to the database with a specific apn
add_ue_with_slice {imsi key opc apn sst sd}: adds a user to the database with a specific apn, sst and sd

You probably used the option add {imsi key opc} and that is why the slice values were left out. Use add_ue_with_slice {imsi key opc apn sst sd instead.

If you have already registered a UE with add {imsi key opc} you can use update_slice {imsi apn sst sd}: adds an slice to an existent UE to modify the slice values of an existing user.

I will close the issue of everything works fine, thanks for using the project!
