11.5 ApplyChargingReport procedure
11.5.1 General description
This operation is used by the gsmSSF to report charging related information to the gsmSCF as requested by the gsmSCF using the "ApplyCharging" operation.
Timing of duration shall be started if answer is detected by the gsmSSF. It shall be started independently for a connection to a Called Party, a Temporary Connection and a gsmSRF connection.
A report is generated as specified in the 3GPP TS 23.078 [42].
11.5.1.1 Parameters
- callResult:
This parameter provides the gsmSCF with the charging related information previously requested using the ApplyCharging operation. The "CallResult" is a list, and can contain the following parameters:
- timeDurationChargingResult:
This is a list, and can contain the following parameters:
- timeInformation:
This is a choice of the following parameters:
- timeIfNoTariffSwitch:
This parameter will be present if no tariff switch has occurred since the reception of the first ApplyCharging operation for the connection to the Called Party, Temporary Connection or gsmSRF connection, otherwise it will be absent.
If Answer was detected for the connection to the Called Party, the Temporary Connection or the gsmSRF connection, then the elapsed time since detection of Answer shall be reported. If answer was not detected, it shall be set to "0".
- timeIfTariffSwitch:

This parameter will be present if a tariff switch has occurred since the reception of the first ApplyCharging operation for the connection to the Called Party, Temporary Connection or gsmSRF connection, otherwise it will be absent.
The parameter may contain the following information:
- timeSinceLastTariffSwitch:

If Answer was detected for the connection to the Called Party, the Temporary Connection or the gsmSRF connection, then the elapsed time since detection of Answer or the last tariff switch (whichever of these events was last detected) shall be reported. If Answer was not detected, it shall be set to "0".
- TariffSwitchInterval:

This parameter is present only if a tariff switch has occurred since the detection of Answer for the connection to the Called Party, the temporary connection or the gsmSRF connection in the reported call period.
The time interval between either the detection of the Answer event or the previous tariff switch (whichever of these events was last detected) and the last tariff switch is reported.
- partyToCharge:
The "partyToCharge" parameter as received in the related ApplyCharging operation or deduced from the default value, to correlate the result to the request.
- callActive:
This parameter indicates whether the call is still active or has been released.
- callReleasedAtTcpExpiry:
This parameter, if present, indicates that the gsmSSF has released the call and terminated the dialogue.
It shall be present when ACR is sent due to Tcp expiry and the gsmSSF has released the call (because ReleaseIfExceeded was present in ACH) and terminated the dialogue.
In all other instances, this parameter shall be absent.
11.5.2 Invoking entity (gsmSSF)
11.5.2.1 Normal procedure
gsmSSF preconditions:
(1) A relationship exists between the gsmSSF and the gsmSCF.
(2) A charging event has been detected that was requested by the gsmSCF via an ApplyCharging operation or a Called Party, Temporary Connection or gsmSRF disconnection event has occurred.
gsmSSF postconditions:
(1) If release of the call has occurred because the allowed call duration has been reached:
- All outstanding EDPs shall be disarmed;
- ApplyChargingReport shall be sent to gsmSCF followed by any outstanding CallInformationReports,
if applicable;
- The gsmSSF shall transit to the 'Idle' state.
(2) If release of the call has occurred but not because the allowed call duration has been reached:
- If there are any outstanding EDPs or other reports then the gsmSSF shall remain in the same state, else;
- The gsmSSF shall transit to the 'Idle' state.
This operation is invoked if a charging event has been detected that was requested by the gsmSCF.
