  • As part of PCC rule definition in CCA or RAR, this AVP is used to rate-limit a flow.

  • The AVP defines QoS overrides that can be submitted from PCRF to the SR OS router in a CCA or RAR message. The overrides are nested in Charging-Rule-Definition AVP and are activated in 7x50 through the Charging-Rule-Install AVP.

The supported QoS overrides are:

  • Queue rates, bursts sizes, and weights

  • Policer rates and burst sizes

  • Subscriber egress aggregate rate limit

  • Arbiter rates

The AVP defines APN Uplink and Downlink Aggregate Maximum Bitrate (AMBR) in a CCA or RAR message. In this case, the AVP is included on the message level. The SR OS can map the AMBR on QoS overrides using the following commands.

  • MD-CLI 
    configure groups group subscriber-mgmt diameter-gx-policy gx three-gpp-qos-mapping
  • classic CLI 
    configure subscriber-mgmt diameter-application-policy gx 3gpp-qos-mapping

For GTP S11 access, the AVP can also be used to signal the APN AMBR value received in GTP in a CCR message. In this case the AVP is included on message level.

1018

Charging-Rule-Report

29.212 / §5.3.18

—

This AVP is of type Grouped and is used to report the status of PCC rules in the 7750 SR.

Rule-Failure-Code

29.212 / §5.3.38

—

This AVP is sent from the router to the PCRF within a Charging-Rule-Report or ADC-Rule-Report AVP to identify the reason a rule is being reported. For the list of supported failure codes in the 7750 SR, see Rule failure codes (Rule-Failure-Code AVP).

1032

RAT-Type

29.212 / §5.3.31

—

This AVP identifies the radio access technology used for this connection.

1066

Monitoring-Key

29.212 / §5.3.59

Gx-UM-ESM

Gx-UM-AA

This AVP is used for usage monitoring, as an identifier for a usage monitoring control instance.

This AVP can be nested within:

  • Charging-Rule-Definition AVP

    In this case, the Monitoring-Key AVP is used to represent the PCC rule for which usage monitoring may be needed.

  • Usage-Monitoring-Information AVP

    In this case, the Monitoring-Key AVP is used to trigger or report the usage monitoring action for the entity represented by the Monitoring-Key AVP.

The usage monitoring can be performed on multiple levels as requested by the Usage-Monitoring-Level AVP nested within the Usage-Monitoring-Information AVP:

  • If the level is IP-CAN session, then the monitoring-key is an arbitrary octet string set by the PCRF – usage monitoring is performed for the entire IP-CAN session (which represent a host/sla-profile instance)

  • If the level is pcc rule, then the Monitoring-Key refers to either the predefined category (name) in the 7750 SR, or the PCC rule represented by the Monitoring-Key AVP as defined in the Charging-Rule-Definition AVP.

  • If the level is adc rule, then the monitoring-key is an arbitrary unique name that refers to a unique Tdf-App-Id defined in an Adc-Rule.

There can be up to three monitoring-keys in a single Gx messages.

1067

Usage-Monitoring-Information

29.212/ §5.3.60

Gx-UM-ESM

Gx-UM-AA

This AVP is of type Grouped and it contains the usage monitoring control information. It is used to activate usage monitoring and grant service units when it is sent from the PCRF toward the 7750 SR.

The 7750 SR uses this AVP to report usage monitoring to the PCRF.

1068

Usage-Monitoring-Level

29.212 / §5.3.61

Gx-UM-ESM

Gx-UM-AA

This AVP is sent by PCRF to indicate the level on which usage monitoring is performed in the 7750 SR:

  • IP-CAN session level

  • PCC rule level

  • ADC rule level

If usage-monitoring-level AVP is not provided, its absence indicates the pcc rule level usage monitoring.

1069

Usage-Monitoring-Report

29.212 / §5.3.62

Gx-UM-ESM

Gx-UM-AA

This AVP is sent by the PCRF to indicate that the accumulated usage monitoring is to be reported by the 7750 SR regardless of whether a usage monitoring threshold is reached. In other words, this AVP indicated immediate request for a usage monitoring report.

A single value for this AVP is defined:

0 — usage_monitoring_report_required

1070

Usage-Monitoring-Support

29.212 / §5.3.63

Gx-UM-ESM

Gx-UM-AA

This AVP is sent by the PCRF to indicate whether the usage monitoring is disabled for specific monitoring key.

The following value is defined:

0 — usage_monitoring_disabled

When usage-monitoring is disabled for a specific monitoring-key in this fashion, the 7750 SR generates a new CCR-u with the event-trigger AVP set to ‛usage_report’ to report the accumulated usage for the disabled usage monitoring entities.

1080

Flow-Direction

29.212 / §5.3.65

Gx-PM-ESM

This AVP is nested within the Flow-Information AVP. It identifies the direction in which the PCC rule is applied (ingress or egress).

Supported values are:

  • DOWNLINK (1) for egress direction
  • UPLINK (2) for ingress direction

The direction to which the PCC rule is applied can come from the following two sources, in the order of preference:

  • Flow-Direction AVP inside of the Flow-Information AVP.

  • Inside of the Flow-Description AVP as part of IPFilterRule type (direction field).

1085

Redirect-Information

29.212/§5.3.82

Gx-PM-ESM

This is a Grouped AVP that contains HTTP redirect information. This can be used in:

  • PCC rules to HTTP redirect a flow or a group of flows.

  • HTTP redirect overrides to override currently applied URL within the subscriber filter.

1086

Redirect-Support

29.212/§5.3.83

Gx-PM-ESM

This AVP is nested inside of Redirect-Information AVP.

The values of this AVPs are:

  • REDIRECTION_DISABLED (0)

  • REDIRECTION-ENABLED (1)

The behavior for Redirect-Support in the 7750 SR is the following:

  • If the AVP value is REDIRECTION_ENABLED, the 7750 SR accepts it and HTTP redirect is in effect.

  • If the AVP value is different from REDIRECTION_ENABLED and M-bit is set (or inherited from parent AVP), the 7750 SR rejects it and the rule fails.

  • If the AVP value is different from REDIRECTION_ENABLED and M-bit is not set in this AVP or any of parent AVPs, the 7750 SR ignores it and the HTTP redirect is not explicitly disabled.

Not receiving this AVP has the same effect as it was received with value REDIRECTION_ENABLED.

1088

TDF-Application-Identifier

29.212/§5.3.77

Gx-UM-AA

This AVP is of type OctetString.

This AVP can be used in both PCC and ADC rules.

ADC-Rule-Definition

29.212 / §5.3.87

Gx-PM-AA

Gx-UM-AA

This AVP is of type Grouped and it contains the rules that are to be activated.

AA rules that can be applied to a subscriber via Gx are:

  • Application-profile activation/override. A preexisting application-profile must be defined in the 7750 SR.

  • Application characteristic overrides.

  • Monitoring Key and a TDF-Application-Identifier. This installation of this rule has the effect of creating a usage monitoring instance for the subscriber for the specified TDF-Application-Identifier.

1096

ADC-Rule-Name

29.212 / §5.3.89

Gx-PM-AA

Gx-UM-AA

This AVP specifies the name of the ADC rule that is applied. This is an arbitrary string assigned by the PCRF and is used by the 7750 SR to report the rule status. In case that AA-Functions AVP is used (app-profile and ASO assignment/modification), this arbitrary name string must be prepended with a 7750 SR reserved keyword ‟AA-Functions:”.

1097

ADC-Rule-Report

29.212 / §5.3.90

Gx-PM-AA

Gx-UM-AA

Standard diameter AVPs (format)

Standard diameter AVPs (format) lists standard diameter AVPs.

Incl/Excl – The attribute can be suppressed via CLI.

Flags (as set by the 7750 SR when the AVP is constructed):

  • V indicates Vendor specific bit.

  • M indicates Mandatory bit.

Note: The P flag bit is always set to 0.

UTF8String is a human-readable string using UTF-8 transformation format (which is for 7-bit encoding the same as US-ASCII).

OctetString is a basic data type which contains an arbitrary data. For example, Charging-Rule-Name AVP is OctetString according to RFC 6733 but in the 7750 SR it is displayed as readable string (UTF8String).

Flags for Gx specific AVPs are defined in RFC 6733, §4.5; 29.212, §5.3.

Flags for the Gx re-used AVPs are set as described in RFC 6733, §4.5 and in 3GPP 29.219, §5.4 — ‟The AVPs from Diameter base protocol are not included in Table 5.4, but they are re-used for the Gx reference point. Unless otherwise stated, re-used AVPs shall maintain their 'M', 'P' and 'V' flag settings. Where 3GPP RADIUS AVPs are re-used, unless otherwise stated, they shall be translated to Diameter AVPs as described in RFC 4005 [12] with the exception that the 'M' flag shall be set and the 'P' flag may be set”.

The NOKIA-specific AVPs will have the M-bit cleared.

NA — This keyword (Not Advertised) denotes that the AVP is not originated by the 7750 SR and therefore the 7750 SR does not set the flag bits. However, the 7750 SR recognizes the AVPs and corresponding values listed in the table, regardless of the M-bit flags set by PCRF. However, if the V-bit is present in the received AVP, then the Vendor-Id filed in the AVP layout also must be present and set to the correct value because the AVP with V-bit set is identified by the <avp-id, vendor-id> pair.

Vendor-Id = 10415 (3GPP)

This is an arbitrary rule name for PCC rules or a predefined string representing the overrides in the 7750 SR. Syntax for predefined names used in overrides are:

Filters:

  • Ingr-v4:<id>

  • Ingr-v6:<id>

  • Egr-v4:<id>

  • Egr-v6:<id>

  • In-Othr-v4:<id> (one-time-http-redirect)

  • Sla-Profile:sla-profile-string (16 Byte)

  • Sub-Profile:sub-profile-string (16 Byte)

  • Inter-Dest:Inter-Dest-String to associate subscriber with Vport

HTTP Redirect Override

  • V4-http-url:url-string

  • V6-http-url:url-string

Category-Map (for usage monitoring):

Cat-Map:category-map-name

HTTP Redirect Override:

  • V4-http-url:url-string

  • V6-http-url:url-string

AA Strings:

  • AA-Functions: <name-string>

    This prefix indicates that the rule contains aa-specific information.

  • AA-UM: <name-string>

    This prefix indicates that the rule contains aa-specific usage-monitoring information, or points to a predefined aa-specific usage-monitoring rule.

Example:

Charging-Rule-Name = ingr-v4:5 ̶ reference to the predefined ingress IPv4 filter in 7450 ESS, 7750 SR, 7950 XRS, and VSR. The filter ID is 5.

Charging-Rule-Name =sla-profile:my-premium-sla ̶ reference to the predefined sla-profile in 7450 ESS, 7750 SR, 7950 XRS, and VSR. The sla-profile name is ‛my-premium-sla’.
