Soluzione

Introduzione

In questo documento viene descritto come risolvere il problema che si verifica quando si verifica un calo degli indicatori di prestazioni chiave (KPI) ASR (4G Attach Success Rate) quando viene aumentato il motivo della disconnessione mme-hss-user-known.

Prerequisiti

Requisiti

Cisco raccomanda la conoscenza dei seguenti argomenti:

- Conoscenze hardware di 5000/5500

Problema

Il provider di servizi ha segnalato la degradazione di 4G ASR in un MME e il motivo di disconnessione 'mme-hss-user-known' è stato aumentato.

Il motivo di disconnessione "mme-hss-user-known(375)" descrive il numero totale di sessioni disconnesse perché l'utente MME HSS è sconosciuto.

Una traccia di errore acquisita ha segnalato che HSS stava rifiutando l'autenticazione come risultato del codice DIAMETER_MISSING_AVP (5005) nel messaggio AIA.

MME riceveva costantemente "DIAMETER_MISSING_AVP (5005)" da HSS ed ecco come appare il messaggio AIA di errore:

Risoluzione dei problemi

In questa sezione vengono fornite informazioni che è possibile utilizzare per risolvere il problema di deterioramento degli indicatori KPI ASR dovuto a un aumento del motivo di disconnessione mme-hss-user-known.

Il "mon sub" raccolto viene tracciato e confrontato con lo scenario di successo e di errore. Nell'AIR manca l'AVP delle funzionalità supportate dal MME al server HSS.

I messaggi AIR e AIA riusciti vengono acquisiti dalla sottotraccia mon. Questo è il messaggio AIR inviato da ME a HSS:

Soluzione

L'AVP "ID fornitore supportati" non sembra essere negoziato con la scheda DPC Card 2, quindi il guasto viene rilevato solo per quella scheda.

Come per la RFC 3588,

Supported-Vendor-Id AVP: utilizzato nei messaggi CER e CEA per informare il peer che il mittente supporta (un sottoinsieme di) le AVP specifiche del fornitore definite dal fornitore identificato nell'AVP.

AVP ID fornitore: in combinazione con AVP ID fornitore supportato, può essere utilizzato per sapere quali attributi specifici del fornitore possono essere inviati al peer.

Al fine di scambiare le capacità tra il diametro peer e il client, questo piano d'azione è suggerito al fornitore di servizi.

Il piano d'azione prevede la migrazione della scheda DPC 2 con la scheda DPC Card 10 in standby.

[local]SGSN-MME-03# card migrate from 2 to 10

Are you sure? [Yes|No]: yes

Il provider di servizi ha eseguito la migrazione della scheda DPC 2 con la scheda DPC in standby 10.

Dopo l'attività, gli ID dei fornitori supportati (10415) sembrano essere corretti per la scheda 10 con il rispettivo hss-peer e anche l'indicatore KPI ASR sembra essere corretto.

Gli ID dei fornitori supportati devono essere del valore '10415' quando viene stabilita una connessione peer con diametro tra MME e HSS per poter scambiare i messaggi di diametro operativo.
