In dit document worden verschillende onderzoeksmethoden beschreven om de Diameter Error Code te verwerken: "IP-CAN_SESSION_NOT_AVAILABLE (5065)
" in Cisco Policy Suite (CPS).
Cisco raadt kennis van de volgende onderwerpen aan:
Opmerking: Cisco raadt aan dat u bevoorrechte toegang tot CPS CLI moet hebben.
De informatie in dit document is gebaseerd op CPS 21.1.
De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u zorgen dat u de potentiële impact van elke opdracht begrijpt.
Diameter-foutcode: "IP-CAN_SESSION_NOT_AVAILABLE (5065)
" is een veelgezien Diameter Experimental-Resultaat-Code in PCRF die behandelt Voice over Long-Term Evolution (VoLTE)
diensten.
Deze fout wordt niet gegenereerd voor een gezond VoLTE-systeem. Er zijn een paar scenario's die in dit document worden besproken waar deze fout wordt gemeld en zijn diverse benaderingen om hen problemen op te lossen.
In het algemeen, als de PCRF er niet in slaagt om een sessie te binden tussen Rx en Gx sessies, dan reageert het op de Application Function (AF)
met een AA-Antwoord, dat een Experimenteel-Resultaat-Code Attribute Value Pair (AVP) omvat dat op de waarde is ingesteld " IP-CAN_SESSION_NOT_AVAILABLE (5065)
".
De basisregel voor de Rx to Gx-sessiebinding is op dezelfde basis gebaseerd Framed-IPv6-Prefix
ontvangen van Gx_Credit Control Request Initial (CCR-I) 543
terwijl de Gx sessie creatie en de ontvangen van Rx_Authorization Authentication Request (AAR)
voor het maken van RX-sessie.
In dit scenario wordt opgemerkt dat alle foutmonsters van IP-CAN_SESSION_NOT_AVAILABLE (5065)
van een specifieke lijst van Framed-IPv6-Prefix
. Deze Framed-IPv6-Prefixes
worden niet gerapporteerd in Gx_CCR-I
.
Deze CLI biedt de unieke lijst en het totale aantal Framed-IPv6-Prefix
waarvoor de IP-CAN_SESSION_NOT_AVAILABLE (5065)
door CPS teruggezet op AF
.
[root@LAB-PCRF02CO-pcrfclient01 broadhop]# zgrep -B80 "IP-CAN_SESSION_NOT_AVAILABLE" consolidated-engine.*.gz | grep "Framed-IPv6-Prefix:" | cut -f3,4,5 -d: | sort| uniq -c
6 2402:XXXX:YYYY
3 2402:PPPP:QQQQ
1 2402:JJJJ:KKKK
Deze CLI biedt de unieke lijst en telling van Framed-IPv6-Prefix
gerapporteerd in Gx_CCR-I
van Packet Data Network Gateway (PGW)
.
[root@LAB-PCRF02CO-pcrfclient01 broadhop]# zgrep -A 50 CCR-I consolidated-engine.*.gz | grep Framed-IPv6-Prefix: | cut -f 3,4,5 -d: | sort | uniq -c
115 2402:AAAA:BBBB
116 2402:NNNN:MMMM
246 2402:SSSS:RRRR
Opmerking: voor de CLI-uitvoering moet u inloggen op pcrfclient01 of CPS en naar /var/log/broadhop/
directory.
De verwachting voor een gezond systeem is: Framed-IPv6-Prefix
ontvangen van Gx_CCR-I
en Rx_AAR
afkomstig zijn van dezelfde IP-prefixgroep die is toegewezen voor Gm IP (PGW naar AF).
In dit scenario is het duidelijk dat voor alle verzamelde foutmonsters Framed-IP-Prefix
gerapporteerd in Rx_AAR
is volledig anders dan de Framed-IP-Prefix
ontvangen in Gx_CCR-I
.
1. Wat is de Gx Stale sessie timer?
Deze timer is gewapend telkens als er een bericht wordt ontvangen of verzonden voor een bepaalde Gx-sessie. Wanneer de timer verloopt, wordt een Gx_Re-Auth-Request (RAR)
wordt verzonden met Re-Auth-Request-Type AVP
ingesteld op AUTHORIZE_ONLY (0)
voor die Gx-sessie naar PGW. Als een Gx_Re-Auth-Antwoord (RAA) wordt ontvangen terwijl Resultaat-Code AVP waarde is ingesteld op DIAMETER_UNKNOWN_SESSION_ID (5002)
of DIAMETER_UNABLE_TO_COMPLY (5012)
de Gx-sessie wordt als oud beschouwd en uit de interne PCRF-database verwijderd. Op elke activiteit via de Gx-interface (Gx_RAR/Gx_CCR)
, wordt de timer opnieuw ingesteld.
2. Wat is een sessieverlooptimer?
Als er geen berichten worden ontvangen binnen de timer-set, wordt de sessie verwijderd uit PCRF.
In het problematische scenario worden de timers op deze manier ingesteld.
Gx Stale sessie timer: 180 minuten
Verlooptijd sessie: 240 min
In overeenstemming met de timer configuratie, na 180 minuten wordt een Keep living RAR gegenereerd en verzonden naar PGW, en als de sessie 240 minuten inactief is, wordt de sessie verwijderd uit de PCRF DB.
Als de Keep living RAR wordt gemist, vanwege meerdere redenen [Gx interface flap, PGW buiten dienst, of een hoekcase], bereikt de sessie de verlooptijd en op hetzelfde moment als er Rx_AAR ontvangen wordt van AF, kunt u deze fout zien en een Gx_RAR wordt verzonden naar PGW met Session-Release-Cause: UNSPECIFIED_REASON (0)
.

De Gx-sessie is ook gemarkeerd voor zacht wissen bij PCRF. Aangezien PCRF er niet in is geslaagd de Gx-sessie te binden, wordt een Rx_AAA gereageerd met de Experimental-Result-Code AVP ingesteld op de waarde IP-CAN_SESSION_NOT_AVAILABLE (5065)
.

Experimental-Result-Code: IP-CAN_SESSION_NOT_AVAILABLE (5065)
===============================================
Wanneer u de Error KPI-trend nauwkeurig controleert voor RX_AAR [IP-CAN_SESSION_NOT_AVAILABLE (5065)]
en Gx_RAR [DIAMETER_UNKNOWN_SESSION_ID (5002)]
Je kunt de lineaire toename van deze fouten zien na een Gx interface flap.
De oplossing voor dit probleem moet buiten CPS worden uitgevoerd. U moet de IP-pool die in de Gm-interface wordt gebruikt (de interface tussen SPGW en AF) met elkaar in overeenstemming brengen en ervoor zorgen dat dit ook gebeurt Framed-IP-Prefixes
worden gebruikt in zowel PGW als AF voor de User Equipment (UE)
.
Stel de verlooptimer van de sessie in op > (3 * Gx stale-session timer
).
Stap 1. Meld u aan bij Policy Builder met de gebruiker Read/Write.
Stap 2. Stel de Default Gx Stale Session Timer Minutes
als aanbevolen waarde.
Stap 3. Stel de Session Expiration Hours and Session Expiration Minutes
zoals aanbevolen 3 * of Gx Stale session timer
.
Stap 4. Sla de Repository op en publiceer naar de nieuwste versie.
Maak een Rx_ASR
naar AF om de reeds gecreëerde Rx-sessie te verwijderen als CPS Diameter Error Code=5002
Gx_RAR van PGW. Op deze manier, als de sessie niet aanwezig is in PGW, en CPS ontvangt Diameter Error 5002
, samen met de zachte verwijdering van de Gx-sessie, stuurt CPS een Rx_ASR-bericht naar de AF-knooppunt met een Abort-Cause: 0
.
Stap 1. Log in bij de Cluster Manager als basisgebruiker.
Stap 2. Back-upqns.conf
bestand.
cp /etc/broadhop/qns.conf /etc/broadhop/qns.conf.$(date +%m%d%Y).bkp
Stap 3. Het bestand bewerken /etc/broadhop/qns.conf
met vi redacteuren en de regel "-Dsend.Rx.ASR.For.AdditionalErrorCodes=5002
"
Stap 4. Bouw marionettenscript.
/var/qps/install/current/puppet/modules/qps/templates/var/broadhop/build_etc.sh
Stap 5. De wijzigingen in alle VM's invullen.
/var/qps/install/current/scripts/upgrade/reinit.sh
Stap 6. Start alles opnieuw om de wijzigingen effectief te maken.
restartall.sh
Dit is de verwachte vraagstroom na de vereiste parameterverandering.
Dit is de verwachte gespreksstroom uit het CPS-motorlog na de vereiste parameterwijziging.
