2 Advice of Charge (Charging) (AoCC)

04.863GPPAdvice of Charge (AoC) supplementary servicesStage 3TS

2.1 Normal operation with successful outcome

On every successful request for an applicable telecommunications service, the served MS will be provided with charging information.

The network sends the Charge Advice Information (CAI) to the MS according to GSM 02.24, GSM 02.86 and GSM 03.86. With this information the MS is able to calculate the units associated with the requested service in real time. In the case where the served mobile is to be charged for multi party calls, separate processes within the MS are used to calculate units appropriate to each call. For unit calculation, each call is treated in the same way as a normal "two-party" call. Any change in the charging rate during a call may be indicated to the MS.

2.1.1 Call re-establishment

When the MS detects a radio link failure, the Chargeable Duration (CDUR) shall be suspended.

If a call re-establishment procedure is attempted, the MS shall resume the CDUR when:

– an MM connection has been successfully completed; and

– a TCH has been successfully seized in the appropriate mode.

2.1.2 MS originated call

For an MS originated call, charging information is transferred to the MS as shown in figure 2.1. The charging information is acknowledged in a FACILITY message only if the MS supports the AoCC functionality specified in GSM 02.24 and GSM 02.86. AoCC refers to the Advice of Charge (Charging) service.

2.1.4 Change of charging information

To inform the MS of a change in charging information the procedure of figure 2.3 is performed. The charging information is acknowledged only if the MS supports the AoCC functionality specified in GSM 02.24 and GSM 02.86.

2.2 Normal operation with unsuccessful outcome

If timer T(AoC) (see GSM 03.86) expires before the Charge Advice Information is acknowledged, the network shall release the call. The MS and network shall act in accordance with GSM 04.08 network initiated call clearing procedures (see figure 2.4).
