Use this command to delay charging until HTTP response for the configured HTTP request method(s). This CLI command is introduced in support of the Response-based Charging feature. This feature is limited to specified HTTP methods.


Important

Response-based charging is supported only for the HTTP protocol.

The Service Scheme configuration is required to configure and enable this feature for a subscriber. For more information on the Response-based TRM feature, see the ECS Administration Guide.

Entering the above command sequence results in the following prompt: 

[local]host_name(config-acs-trig-action)#

Syntax

[ no ] throttle-suppress

no

Disables the Location based QoS Override feature for the subscriber.

throttle-suppress

This keyword allows the operators to suppress the throttling when the subscriber is in a particular LAC or TAC location.

Usage Guidelines

Use this command to perform throttle suppression to provide unlimited bandwidth based on the subscriber location. This CLI command is introduced to support Location based QoS Override feature.

To enable this feature for the subscriber, both local-policy and service-scheme framework must be configured. For redundancy support, the corresponding ICSR configuration must also be present.

The service-scheme framework helps in overriding feature behavior specific to a subscriber or a set of subscribers. The user can update the policies specific to subscribers based on pre-configured events. For more information on the service-scheme framework, see the ECS Administration Guide.


Important

This feature requires the license to configure local-policy. For more information on the licensing requirements, contact Cisco account representative.

The previous implementation limits the subscriber bandwidth based on QoS provided by PCRF in order to comply with 3GPP standards. In release 20.2 and beyond, subscriber is provided with unlimited bandwidth by allowing QoS override based on LAC and/or TAC (individual or range) configured in a local-policy (LP) rule on the gateway. If the subscriber is in the LAC or TAC region and hits the LP rule, the gateway ignores the QoS limits imposed by PCRF and allows the subscriber to have unlimited bandwidth.

For more information on this feature, see the ECS Administration Guide.

Example

The following command enables throttle suppression for the subscriber: 
throttle-suppress

This feature is applicable to all HTTP transactions of a method type for the subscriber, when an HTTP method is configured.


Important

Response-based TRM is supported only for the HTTP protocol.

The Service Scheme configuration is required to configure and enable this feature for a subscriber. For more information on the Response-based charging feature, see the ECS Administration Guide.
