Value as configured in the diameter application policy:

configure subscriber-mgmt diameter-application-policy application-policy-name gy avp-subscription-id {circuit-id | subscriber-id | imsi | msisdn | imei} [type {e164 | imsi | nai | private}]

values:

  • e164: identifier in international E.164 format (ITU-T E.164)

  • imsi: identifier in international IMSI format (ITU-T E.212)

  • nai: identifier in the form of a Network Access Identifier (RFC 2486)

  • private: a credit control server private identifier

default: type private

For GTP access, the configured value is ignored and the type is set to imsi and msisdn respectively for each of the two included Subscription-Id AVPs.

Value as configured in the diameter application policy:

configure subscriber-mgmt diameter-application-policy application-policy-name gy avp-subscription-id {circuit-id | subscriber-id | imsi | msisdn | imei} [type {e164 | imsi | nai | private}]

Note that there is no check if the provided data is in the format of the configured type.

values:

  • circuit-id

  • subscriber-id

  • imsi

  • msisdn

  • imei

default: avp-subscription-id subscriber-id

For GTP access, the Subscription ID data is learned from GTP and contains the IMSI and MSISDN.

  • <DiameterIdentity> is the configured origin host

  • <high 32 bits> are encoded as the Diameter initialization time (the number of seconds since 1 Jan 1970)

Overrides the configured failover value in configure subscriber-mgmt diameter-application-policy application-policy-name on-failure [failover {enabled | disabled}] [handling {continue | retry-and-terminate | terminate}]

Values:

0 = Failover Not Supported

1 = Failover Supported

427

Credit-Control-Failure-Handling

Action to take when the Credit Control client does not receive a valid CCA message within the interval specified with tx-timer (default 10s).

Overrides the configured failure handling: configure subscriber-mgmt diameter-application-policy application-policy-name on-failure [failover {enabled | disabled}] [handling {continue | retry-and-terminate | terminate}]

Values:

0 = Terminate

1 = Continue

2 = Retry and terminate

Threshold preventing time quota exhaustion before refreshing. When the used time quota exceeds the threshold, a CCR-U is triggered with Reporting Reason AVP set to 0 (Threshold).

Value in seconds

3GPP – 869

Threshold preventing volume quota exhaustion before refreshing. When the used volume quota exceeds the threshold, a CCR-U is triggered with Reporting Reason AVP set to 0 (Threshold).

Value in octets

3GPP – 871

Quota-Holding-Time

Specifies an idle-timeout associated with the granted service units. If no traffic associated with the quota is observed for the time specified by the quota holding time, then a CCR-U is triggered with Reporting Reason AVP set to 1 (Quota Holding Time). The idle time is measured per sampling period.

Redirect-Server

↳ (grouped AVP)

This AVP is included when the Final-Unit-Action AVP is set to REDIRECT (1) and contains the URL to which the user must be redirected. The URL overrides the URL specified with configure subscriber-mgmt category-map category-map-name category category-name exhausted-credit-service-level ingress-ip-filter-entries entry entry-id action http-redirect url allow-override.

The AVP is ignored when the out-of-credit action is different from change-service-level or when no http-redirect action with allow-override is configured.

449

Final-Unit-Action

If the value is Terminate, then the session is terminated and the corresponding subscriber host deleted.

If the value is Redirect or Restrict Access, then the out-of-credit action as configured for that rating group (category) is executed:

configure subscriber-mgmt credit-control-policy policy-name out-of-credit-action change-service-level {continue | disconnect-host | block-category | change-service-level}

or

configure subscriber-mgmt category-map category-map-name category category-name out-of-credit-action-override {continue | block-category | change-service- level}

Values:

0 = Terminate

1 = Redirect

2 = Restrict Access

433

Redirect-Address-Type

Must be set to URL (2). The Redirect-Server-Address AVP is ignored when set to a different value.

435

Redirect-Server-Address

Contains the IPv4 HTTP redirect URL that is used when the Final-Unit-Action REDIRECT is triggered for the rating group that corresponds with the MSCC in which the Final-Unit-Indication AVP is included.

The URL specified in the Redirect-Server-Address AVP is only used when all following conditions are met:

  • The Final-Unit-Indication AVP is present in the Multiple-Services-Credit-Control AVP

  • The Final-Unit-Action is set to REDIRECT (1)

  • The Redirect-Address-Type is set to URL (2)

  • The out-of-credit action for the corresponding rating group is set to change-service-level:

    configure subscriber-mgmt credit-control-policy policy-name out-of-credit-action change-service-level

    or

    configure subscriber-mgmt category-map category-map-name category category-name out-of-credit-action-override change-service-level

  • An IPv4 HTTP redirect action with allow-override is specified as exhausted-credit-service-level for the corresponding rating group: configure subscriber-mgmt category-map category-map-name category category-name exhausted-credit-service-level ingress-ip-filter-entries entry entry-id action http-redirect url allow-override

435 (continued)

In all other cases, the Redirect-Server-Address AVP is ignored.

The maximum URL length is 255 characters and can include the same macro substitutions such as $IP (customer's IP address), $MAC (customer's MAC address), $URL (original requested URL), as supported for a static configured HTTP redirect URL.
