OverrideSessionRule

This section describes the parameters for the OverrideSessionRule configurations.

The OverrideSessionRule service configuration is used to override the N7 default bearer QoS APN AMBR UL/DL values.

PCF first evaluates the derived QoS values for default bearer and then assesses the table provided in OverrideSessionRule service configuration using the key values. It further determines the result APN AMBR UL/DL values. If the "Condition to Override" is "LT", then PCF limits the derived QoS values with these override values. If the "Condition to Override" is "GT", then PCF selects the maximum UL/DL among the derived values and overrides these values.

Note

The OverrideSessionRule configuration works in conjunction with the SessionRuleAction configuration.

For information on SessionRuleAction, see SessionRuleAction.

Before setting the service parameters, ensure that you create a use case template and add a service for this configuration. For details, see Configuring the Use Case Template and Adding a Service.

The following table describes the OverrideSessionRule service parameters.

OverrideSessionRule Parameters

Parameters

Description

Priority

Indicates the priority of the server when sending requests. Higher number is equal to higher priority.

Stg Reference

Refers to the STG that contains the QoS reference and the QoS parameter values such as QCI and APN-MBRUL.

List Of Input Column Avp Pairs (List)

The list that specifies the mapping for input (key) columns to determine their values. Based on these values, the STG is queried.

ColumnAndAvpPair

  • Avp Name: Specify the AVP name whose value is used to map to the corresponding key Column for querying the STG.

  • Column: The key column in the STG that corresponds to the specified AVP.

Apn Agg Max Bit Rate U L

Reference to the STG output column that gives the "APNAggregate-Max-Bitrate-UL" value for limiting QoS. This value and the corresponding value derived after QoS actions are compared to determine the final value for APN-Aggregate-Max-Bitrate-UL.

Apn Agg Max Bit Rate D L

Reference to the STG output column that gives the "APNAggregate-Max-Bitrate-DL" value for limiting QoS. This value and the corresponding value derived after QoS actions are compared to determine the final value for APN-Aggregate-Max-Bitrate-DL.

Condition to Override

Provides the condition to compare the values. Only two values are supported "LT" and "GT".

If LT is selected, PCF uses the lowest QoS parameter value from the two QoS references.

If GT is selected, PCF considers the highest QoS parameter value from the two QoS references.

Possible Values:

  • LT: Less than (Default)

  • GT: Greater than
