CSCui04167 - PGW LORC mechanism for subscriber billing
Feature Changes
Overcharging Protection on the S-GW
Consider the following scenario:
1. When a subscriber has an active session and loses coverage or when the subscriber is Idle, the P-GW is not
aware of the subscriber state.
2. If there is valid Downlink Data for the subscriber, the P-GW forwards the data to the S-GW and counts the data
towards appropriate Rf and Gy records.
3. In scenarios when the subscriber loses RF coverage or when the subscriber is not reached via paging, the data is
dropped at the S-GW and causes an overcharge to users.
The software has been enhanced so that the P-GW stops billing of the data in such scenarios. The S-GW notifies the P-
GW of the subscriber state about when to pause and resume charging of the subscriber, this will reduce the overcharging
of the subscriber.
GW of the subscriber state about when to pause and resume charging of the subscriber, this will reduce the overcharging
of the subscriber.
Customer Impact: Huge reduction in overcharging by the P-GW in the above scenarios. This feature is supported only
for Pure S calls on the SAE-GW.
