This MIB module manages the charging related
function on the GGSN node of a GPRS system.

Charging information in GPRS is collected for each MS
by SGSNs and GGSNs that are serving that MS. The GGSN
collects charging information for each MS based on
both external data network usage and the GPRS network
resources.

to be in SPGW mode.
larmNotif signifies that a GPRS related
alarm is detected in the managed system.
This alarm is sent after an entry has been added to
cgprsCgAlarmHistTable or cgprsCgGatewayGroupAlarmHistTable.
This notification is deprecated by
cgprsCgGatewayGroupAlarmNotif
cgprsCgGatewaySwitchoverNotif
.1.3.6.1.4.1.9.9.192.2.0.2
tion of this type is generated when the
charging gateway is switched, the new charging
gateway is identified by cgprsCgActiveChgGatewayAddress
and the old charging gateway is identified by
cgprsCgOldChgGatewayAddress.
The switchover will happen according to the value set
in cgprsCgGroupSwitchOverTime and the selection of the
new CG will be according to the value set in
cgprsCgSwitchOverPriority.
Note: Selection of new CG based on the value set in
cgprsCgSwitchOverPriority is only true for default
charging gateway group, for other charging gateway groups
including defualt charging gateway group it can be determined
by the value set in cgprsCgGroupSwitchOverPriority.

cgprsCgInServiceModeNotif
.1.3.6.1.4.1.9.9.192.2.0.3
tion of this type is generated when the
GGSN charging function is in normal mode. This can
be identified by cgprsCgServiceMode object for default
charging gateway group whereas for other charging groups,
including default charging gateway group it can be identfied
by cgprsCgGroupServiceMode.
This notification is deprecated by
cgprsCgGatewayGroupInServiceModeNotif
cgprsCgMaintenanceModeNotif
.1.3.6.1.4.1.9.9.192.2.0.4
tion of this type is generated when the
GGSN charging function is in maintenance mode. This
can be identified by cgprsCgServiceMode object for default
charging gateway group whereas for other charging groups,
including default charging gateway group it can be identfied
by cgprsCgGroupServiceMode.
This notification is deprecated by
cgprsCgGatewayGroupMaintenanceModeNotif
