GTPP Accounting Support Configuration

This section provides instructions for configuring GTPP-based accounting for subscriber PDP contexts. GTPP-based
accounting for a subscriber can be configured by CGF server configuration in a GTPP group. Additionally individual
CGF server can be configured with this example.
Important:
Reference.
When the GTPP protocol is used, accounting messages are sent to the charging gateways (CGs) over the Ga interface.
The Ga interface and GTPP functionality are typically configured within the system‟s source context. CDRs are
generated according to the interim triggers configured using the charging characteristics configured for the GGSN, and a
CDR is generated when the session ends.
GTPP version 2 is used by default. However, if version 2 is not supported by the CGF, the system reverts to using GTPP
version 1. All subsequent CDRs are always fully-qualified partial CDRs. For CDR encoding different dictionaries are
supported. For more information on GTPP dictionaries, refer AAA Interface Administration and Reference.
Whether or not the GGSN accepts charging characteristics from the SGSN can be configured on a per-APN basis based
on whether the subscriber is visiting, roaming or, home.
By default, the GGSN always accepts the charging characteristics from the SGSN. However it accepts charging
characteristics from RADIUS too, they must always be provided by the SGSN for GTPPv1 requests for primary and
secondary PDP contexts.
If the system is configured to reject the charging characteristics from the SGSN, the GGSN can be configured with its
own that can be applied based on the subscriber type (visiting, roaming, or home) at the APN level (refer to the APN
Configuration section of this chapter for more information). GGSN charging characteristics consist of a profile index
and behavior settings (refer to the GGSN Service Configuration section of this chapter for more information). The
profile indexes specify the criteria for closing accounting records based specific criteria (refer to the GGSN Service
Configuration section of this chapter for more information).
Important:
GGSN service. Commands that configure additional GTPP accounting properties are provided in the Command Line
Interface Reference.
These instructions assume that you have already configured the system level configuration as described in System
Administration Guide and GGSN service as described in GGSN Service Configuration section of this chapter.
To configure the GTPP accounting support for a GGSN service:
Step 1
Create the GTPP group in accounting context by applying the example configuration in the GTPP Group Creation
section.
Step 2 Configure the charging agent and GTPP server (CGF) related parameters for the GTPP accounting support by applying
the example configuration in the GTPP Group Configuration section.
Step 3
Verify your GTPP group and accounting configuration by following the steps in the GTPP Group Configuration
Verification section.
Step 4 Save your configuration as described in the Verifying and Saving Your Configuration chapter.
