TableDrivenActionOverN28

This section describes the parameters that are required to configure the TableDrivenActionOverN28 service.

The TableDrivenActionOverN28 service configuration evaluates and retrieves action on the received messages. During the policy evaluation, if the TableDrivenActionOverN28 service exists in policy, PCF evaluates the CRD table and determines the action for the implementation on the N28 interface.

Based on the action value, PCF performs the following tasks:

  • If the action value is Update and if the N28 session exists, PCF initiates the Intermediate Spending Limit Report operation.

  • On receiving the Subscription-Update response or timeout, PCF reevaluates the TableDrivenActionOverN28 configuration and determines the next action.

  • If the action value is Reinitiate, PCF terminates the existing session and initiates a new session by sending a subscription request. After PCF terminates the existing session, sync N28 Unsubscribe is sent and the session gets deleted.

The TableDrivenActionOverN28 service configuration accepts only request message attributes for Input column binding. Hence, the attribute value pair (AVP) code must match the JSON path that is received in the message. In addition to message attributes, the following AVP codes are used as input AVP codes:

  • Command-Code—The command code of request message.

  • Application-Id—The Diameter Application Identifier to send the Diameter message.

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 TableDrivenActionOverN28 service parameters.

Note

Select the N28 service configuration object to configure this service.

TableDrivenActionOverN28 Parameters

Parameters

Description

Search Table Group

Enter the table group that you want to search from the custom reference data table.

Note
The STG and the included CRD table can have key columns that may not refer to the message attributes in the inbound message. For example, output of other tables. Therefore, ensure to bind these columns correctly.
  • Input Column Binding—Under this parameter, select a value for the ColumnAndAvpPair parameter.

  • AVP Name—Select the name of the Request Attribute for input for evaluating the custom reference data table.

  • Column—Select the key column in the Search Table Group corresponding to the specified AVP.

Output Column Binding

Under this parameter, select a value for the ColumnAndAvpPair parameter.

  • Avp Name—Select the name of the Request Attribute to which the value of the output column is mapped.

  • Column—Select the CRD table column for the output AVP.

Note
The list of Output column to AVP bindings supports only one column or AVP binding for fixed AVP code Action-Over-N28.
