| Description | Charging Gateway table. Charging information in GPRS
is collected for each MS by SGSNs and GGSNs that are serving
the MS. The information that the operator uses to generate
the bill to a subscriber is operator-specific, such as
usage of the radio interface, PDP addresses, duration of
PDP context, usage of general GPRS resources, location of
MS, traffic distination, usage of external data network
and so on.
Charging Gateways act as a storage buffer for real time
Charging Data Record (CDR) collection. It provides the
CDRs to the billing system.
Charging Gateway Table lists all the charging gateways
and their operational states. Backup charging gateway type
is not allowed if there is no primary charging gateway type
entry in the table. In addition, there is only one primary
charging gateway entry. |
