Charging Characteristics
Whether or not the GGSN accepts charging characteristics from the SGSN, the accounting protocol can be configured
on a per-APN basis based on whether the subscriber is visiting, roaming, or home.
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. They will be provided by the SGSN
for GTPv1 requests for primary PDP contexts. If they are not provided for secondary PDP contexts, the GGSN re-uses
those from the primary. The charging characteristics field is optional. If not provided by SGSN, the GGSN selects the
locally configured values. Also, there is a provision to override the values from RADIUS as indicated in the following
table.

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. The charging
characteristics consists of a string of 16 bits designated as profile index and behavior settings. The GGSN supports up to
16 profile indexes numbered 0 through 15 whereas P-GW/S-GW supports up to a maximum of 256 charging profiles.

The profile indexes specify the criteria for closing accounting records based on specific criteria.
