Configuring GTPP Accounting Support
This section provides instructions for configuring GTPP-based accounting which allows the SGSN to send M-CDR
and/or S-CDR accounting data to the Charging Gateways (CGs) over the Ga interface.
and/or S-CDR accounting data to the Charging Gateways (CGs) over the Ga interface.
The Ga interface and GTPP functionality are typically configured within a separate charging context.
The SGSN begins to generate M-CDR data upon GPRS/IMSI attach. S-CDR data generation begins upon PDP context
activation.
activation.
Accounting servers can be configured individually or as GTPP accounting server groups. GTPP accounting server
groups can each have completely different GTPP settings configured. Although a GTTP server can be included in
multiple GTPP groups.

Any GTPP accounting servers configured at the context level that are not specifically configured as part of a GTPP
group, are automatically assigned to be part of the GTPP server group called default that is part of every context.

A maximum of 8 GTPP named server groups can be configured across all contexts. A maximum of 4 CGFs can be
configured in each GTPP server group. A total of total 32 CGFs can be configured across all server groups, including
the server group called default, in one context. Each GTPP group must have unique GTPP charging agents (CGFs)
configured.

configured.
Important:
The system supports the specification of the UDP port number for the charging agent function on the
system and for the CG. The default charging agent port is 49999. The default CG Server port is (3386). If an SGSN
service and a GGSN service are both configured on this system be sure that the UDP ports are unique for each type of
service. Refer to the Command Line Interface Reference for information on changing the ports used.

To configure the GTPP accounting support for a SGSN service:
Step 1
Create the GTPP group in accounting context by applying the example configuration in the Creating GTPP Group
section.
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 Configuring GTPP Group section.

Step 3
Verify your GTPP group and accounting configuration by following the steps in the Verifying GTPP Group
Configuration section.

Step 4
Save your configuration to flash memory, an external memory device, and/or a network location using the Exec mode

Creating GTPP Group
Use the following example to create the GTPP group to support GTPP accounting:
