3G-2G Location Change Reporting
With Location Change Reporting enabled, the SGSN facilitates location-based charging on the GGSN by providing the
UE’s geographical location information when the UE is in connected mode.

Location-based charging is a values-added function that ensures subscribers pay a premium for location-based services,
such as service in a congested areas. With the required feature license installed, the operator uses the CLI to enable the
reporting independently for each network access type: GPRS (2G) or UMTS (3G).

Accounting Path Framework, New for 14.0
As of Release 14.0, the SGSN uses a new accounting path framework to support PSC3 numbers of 8 million attached
subs and 16 million PDP contexts. In the old accounting path framework, there was one AAA session per sub-session in
the Session manager and one archive session per sub-session in AAA manager. As part of the new accounting path
framework there is only one AAA session per call in the Session manager and one archive session per call in the AAA
manager. Also, there is an additional accounting session in the Session manager and the AAA manager per sub-session.
The new accounting path framework improves memory and CPU utilization and prevents tariff or time limit delay.
There are no changes in the CLI syntax to support the new accounting path and the existing accounting behavior of
SGSN is not modified.
