# GGSN Charging Gateway Status

## Procedure

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 Gateway Status from the Category drop-down box.

The following information appears:

> Reject on No-profile Match (cgprsCgChargingCharReject)

> Service Mode (cgprsCgServiceMode)

> Generate Partial CDRs (cgprsCgPartialCdrGenEnable)

> Enable Switch Over Priority (cgprsCgSwitchOverPriority)

> Add Charging Characteristic Selection Mode (cgprsCgCharSelectionMode)

> Reconnect Timer (cgprsCgReconnect)

> Enable PTC IE in CDR (cgprsCgPtcEnable)

> Send Possibly Duplicate Record in CDR (cgprsCgPtcPossiblyDupEnable)

> Active Charging Gateway (cgprsCgActiveChgGatewayAddress)

> Previous Active Charging Gateway (cgprsCgOldChgGatewayAddress)

### Reject on No-profile Match (cgprsCgChargingCharReject)

Specifies whether an incoming Packet Data Protocol (PDP) create request is rejected when either a matching charging profile is not configured or an overriding profile is not present.

> If set to true, the PDP create request is rejected.

> If set to false, the PDP create request is accepted and the default charging profile is applied to it.

### Service Mode (cgprsCgServiceMode)

Indicates the current service mode for charging gateways. There are two possible values:

> operational: Charging gateways operate as they normally do.

> maintenance: The transmission of CDRs to other charging gateways does not take place. However, the collection of CDRs continues as expected.

### Generate Partial CDRs (cgprsCgPartialCdrGenEnable)

When set to true, the GGSN generates partial CDRs. A partial CDR is a secondary CDR in which some of the fields that cannot be modified during the life of the PDP are not included.

A primary CDR refers to the first CDR opened in response to a PDP create request. Subsequent CDRs, called secondary CDRs, are opened when the primary CDR is closed by a trigger event such as exceeding the data volume limit.

### Enable Switch Over Priority (cgprsCgSwitchOverPriority)

This object is used to enable the switch over priority mechanism.

> When set to true, if a charging gateway with a higher priority than the active charging gateway comes up, it then becomes the active charging gateway.

> When set to false, the current active charging gateway remains so, even if a charging gateway with a higher priority comes up.

### Add Charging Characteristic Selection Mode (cgprsCgCharSelectionMode)

When set to true, the charging characteristic selection mode is added to the CDR.

### Reconnect Timer (cgprsCgReconnect)

Indicates whether the charging reconnect feature is enabled. When enabled, the GGSN will attempt to reconnect with a charging gateway that was unreachable due to transient network or link failures. This feature is available when an unreachable charging gateway is using the UDP path protocol and the charging gateway can respond to, but not send, echo requests.

Note: By default, this feature is disabled.

### Enable PTC IE in CDR (cgprsCgPtcEnable)

When set to true, the GGSN includes the Packet Transfer Command (PTC) IE with the CDR message. The value set for the IE is Send Data Record Packet if cgprsCgPtcPossiblyDupEnable is set to false and the possibility of a duplicate Data Record Packet has been ruled out.

Note: This object cannot be set to false if cgprsCgPtcPossiblyDupEnable is set to true.

### Send Possibly Duplicate Record in CDR (cgprsCgPtcPossiblyDupEnable)

When set to true, the GGSN includes the PTC IE with the CDR message. The value set for the IE is Possibly Duplicate Record when the CDR packet is directed to a secondary CGF (by a CDR generating node) because the currently used CGF is not working or the CDR transfer is not working properly.

Note: This object is relevant only when cgprsCgPtcEnable is set to true.

### Active Charging Gateway (cgprsCgActiveChgGatewayAddress)

IP address of the active charging gateway. The address type is indicated by cgprsCgActiveChgGatewayAddrType.

### Previous Active Charging Gateway (cgprsCgOldChgGatewayAddress)

IP address of the previous active charging gateway. The address type is indicated by cgprsCgActiveChgGatewayAddrType.
