# GGSN Charging Info Extension

Use this dialog to view GGSN charging information details.

## Procedure

1. Right-click the device and then select Configure, or double-click the device.

2. Select GGSN Charging Info Extension from the category list.

The following information appears:

> 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 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.

### Release (cgprsCgRelease)

Release specific parameters that need to be used when communicating with the CG. For example, Qos profile information, charging characteristics field, etc.

### GTP Short Header (cgprsCgGtpShortHeaderEnable)

Enables GGSN to use the 6-byte GTP short header for charging transactions. Toggle is not possible when there are pending CDR's.

### Data Record Transfer Format (cgprsCgTransFormNumRespEnable)

- true means the data record transfer response IE uses is the one octet format which contains the number of records responded.

- false means the data record transfer response IE uses is the 2-octet format which contains the length of this IE.

Toggle is not possible when there are active MS sessions on GGSN.

### Charging Container Time-trigger (cgprsCgContainerTimeLimit)

A G-CDR is used to collect charging information related to the packet data information for a GPRS mobile in the GGSN.The List of Traffic Data Volumes attribute of the G-CDR consists of a set of containers, that can be closed on certain trigers conditions like,

- Data volume limit

- Time duration limit

- Maximum number of change condition limit

This object when set to some non-zero time value, enables the G-CDR updation when the time limit is reached.
