Feature Description

When UPF detects a GTP-U path failure, it sends Node Report Request (with NodeID and GTPU Peer Information) to cnSGW-C. cnSGW-C clears the PDU sessions belonging to the GTP-U peer and UPF node ID.

This feature supports the following:

  • Sending Node Report Success

  • Cleaning session or bearer based on the reported value in node-report (Node-ID and Peer Information)

  • Incrementing the relevant statistics

For more information, see the UCC Serving Gateway Control Plane Function - Configuration and Administration Guide > GTPU Path Failure chapter.

Behavior Change

Previous Behavior: In releases prior to 2021.02.3, multiple set of entries for IMSI, MSISDN, and IMEI were displayed as an output of show subscriber command.

Old sample output:

["key:imsi-123456789012348",
"imei:123456786666660",
"imsi:123456789012348",
"msisdn:223310101010101",
"id-index:1:1:33587200",
"id-value:2051",
"secKey:imei-123456786666660",
"upf:10.1.6.200",
"upfEpKey:10.1.6.200:10.1.6.199",
"s5s8Ipv4:10.1.6.198",
"s11Ipv4:10.1.6.200",
"namespace:sgw",
"nf-service:sgw"
]

New Behavior: In 2021.02.3 and later releases, only single set of entries for IMSI, MSISDN, and IMEI is displayed. MSISDN display is changed to from msisdn: <msisdn_number> to msisdn:msisdn-<msisdn_number>.

The following show commands display single set of entries for IMSI, MSISDN, and IMEI.

  • show subscriber all

  • show subscriber namespace sgw all

  • show subscriber nf-service sgw all


Important

MSISDN display is not changed for the following command:

show subscriber namespace sgw imsi <imsi_value> full command

New sample output:

  • 15 Digit IMEI:

    ["id-index:1:1:33587200",
"id-value:3",
"imsi:imsi-123456789012348",
"msisdn:msisdn-223310101010101",
"imei:imei-123456786666660",
"upf:10.1.6.200",
"upfEpKey:10.1.6.200:10.1.6.199",
"gtpuPeerIpv4:10.1.6.200:10.1.6.198",
"s5s8Ipv4:10.1.6.198",
"gtpuPeerIpv4:10.1.6.200:10.1.6.200",
"s11Ipv4:10.1.6.200",
"namespace:sgw",
"nf-service:sgw"
]

  • 16 Digit IMEI:

    ["id-index:1:1:33587200",
"id-value:3",
"imsi:imsi-123456789012348",
"msisdn:msisdn-223310101010101",
"imei:imeisv-1234567866666600",
"upf:10.1.6.200",
"upfEpKey:10.1.6.200:10.1.6.199",
"gtpuPeerIpv4:10.1.6.200:10.1.6.198",
"s5s8Ipv4:10.1.6.198",
"gtpuPeerIpv4:10.1.6.200:10.1.6.200",
"s11Ipv4:10.1.6.200",
"namespace:sgw",
"nf-service:sgw"
]

Note

  • imsi displays the IMSI of the session.
