# GGSN Charging Info Extension

From this dialog box, you can view GGSN charging information details.

## Navigation

1. Right-click the Multi-processor WAN Application Module (MWAM) and then select Configure, or double-click the module.

2. Select MWAM module from the Category drop-down box.

3. With a device selected in the MWAM module dialog box, click Configure.

4. Select GGSN Charging Info Extension from the Category drop-down box.

The following information is displayed:

> Latest Charging Gateway Id (cgprsCgAlarmHistLatestIndex)

> Max SGSN changes to trigger G-CDR (cgprsCgCdrSgsnChangeLimit)

> Release (cgprsCgRelease)

> GTP Short Header (cgprsCgGtpShortHeaderEnable)

> Data Record Transfer Format (cgprsCgTransFormNumRespEnable)

> Charging Container Time-trigger (cgprsCgContainerTimeLimit)

### Latest Charging Gateway Id (cgprsCgAlarmHistLatestIndex)

The value of cgprsCgAlarmHistIndex for the most recently created entry in cgprsCgAlarmHistTable.

### Max SGSN changes to trigger G-CDR (cgprsCgCdrSgsnChangeLimit)

Maximum number of Serving GPRS Support Node (SGSN) changes that trigger the closure of G-CDR or partial record. When the maximum number is reached, the record is closed and a new partial record is opened. When the value is zero, then for every SGSN change, the G-CDR or partial record is closed. If this value is set to -1, then the number of SGSN changes is not associated with the closure of G-CDR or creation and closure of a partial record.

Valid values for this object range from -1 to 15.

### Release (cgprsCgRelease)

Release specific parameters that need to be used when communicating with the charging gateway; for example, QoS profile information, charging characteristics field, etc.

### GTP Short Header (cgprsCgGtpShortHeaderEnable)

Enables Gateway GPRS support node (GGSN) to use the 6-byte GPRS Tunneling Protocol (GTP) short header for charging transactions. Toggle is not possible when there are pending CDRs.

### Data Record Transfer Format (cgprsCgTransFormNumRespEnable)

When the value of this object is true, the data record transfer response IE uses is the one octet format which contains the number of records responded. When the value of this object is false, means the data record transfer response IE uses is the 2-octet format which contains the length of this IE.

### Charging Container Time-trigger (cgprsCgContainerTimeLimit)

When set to a non-zero time value, the G-CDR is updated when the configured time limit is reached.

A G-CDR is used to collect charging information related to the packet data information for a General Packet Radio Service (GPRS) mobile in the GGSN. The G-CDR's List of Traffic Data Volumes attribute consists of a set of containers that can be closed when certain conditions are met like:

> a data volume limit

> a time duration limit

> the maximum number of change condition limit
