Hi,

I have deployed open5gs and configured a subscriber with below command

open5gs-dbctl add_ue_with_slice imsi-999700000000001 465B5CE8B199B49FAA5F0A2EE238A6BC E8ED289DEBA952E4283B54E88E6183CA internet 1 0x111111

Also verified the same on mongodb.

`> db.subscribers.find() { "_id" : ObjectId("65ae4932d9685518c5e4c37e"), "schema_version" : 1, "imsi" : "imsi-999700000000001", "msisdn" : [ ], "imeisv" : [ ], "mme_host" : [ ], "mm_realm" : [ ], "purge_flag" : [ ], "slice" : [ { "sst" : 1, "sd" : "0x111111", "default_indicator" : true, "session" : [ { "name" : "internet", "type" : 3, "qos" : { "index" : 9, "arp" : { "priority_level" : 8, "pre_emption_capability" : 1, "pre_emption_vulnerability" : 2 } }, "ambr" : { "downlink" : { "value" : 1000000000, "unit" : 0 }, "uplink" : { "value" : 1000000000, "unit" : 0 } }, "pcc_rule" : [ ], "_id" : ObjectId("65ae4932d9685518c5e4c37f") } ], "_id" : ObjectId("65ae4932d9685518c5e4c380") } ], "security" : { "k" : "465B5CE8B199B49FAA5F0A2EE238A6BC", "op" : null, "opc" : "E8ED289DEBA952E4283B54E88E6183CA", "amf" : "8000" }, "ambr" : { "downlink" : { "value" : 1000000000, "unit" : 0 }, "uplink" : { "value" : 1000000000, "unit" : 0 } }, "access_restriction_data" : 32, "network_access_mode" : 0, "subscribed_rau_tau_timer" : 12, "__v" : 0 }

`

When a call is made, UDR sends 404

What could be issue here?

Hi,

I think your issue is the format of the IMSI. You've put "imsi-999700000000001" and you only need to put "999700000000001".

Try this and give me feedback if this solves your issue.

Cheers, Álvaro

Hi Álvaro,

Thanks for the quick response and pointing it out. Yes, this was the issue. After correcting it, I can see registration is complete.

Thanks Nitin
