Dear free5gc support,
I’m using an external gnb simulator, in Registration procedure, UE got authentication reject from AMF after UE sends authentication response. Would you pls help.
Thanks a lot!
And here is my UE data in mongodb:
db.subscriptionData.authenticationData.authenticationSubscription.find()
{ “_id” : ObjectId(“5f2b3da520781a45a76133f5”), “permanentKey” : { “encryptionKey” : 0, “encryptionAlgorithm” : 0, “permanentKeyValue” : “8baf473f2f8fd09487cccbd7097c6862” }, “sequenceNumber” : “16f3b3f70fc2”, “authenticationManagementField” : “8000”, “milenage” : { “op” : { “encryptionAlgorithm” : 0, “opValue” : “8e27b6af0e692e750f32667a3b14605d”, “encryptionKey” : 0 } }, “opc” : { “opcValue” : “”, “encryptionKey” : 0, “encryptionAlgorithm” : 0 }, “ueId” : “imsi-2089300007487”, “authenticationMethod” : “5G_AKA” }
Below is log from AMF, would you pls help on what is the reason:
