0  ScopeWord‑p. 5
The present document specifies the procedures used at the radio interface (reference point Um as defined in TS 24.002) for normal operation, registration, erasure, activation, deactivation, invocation and interrogation of charging supplementary services. The provision and withdrawal of supplementary services is an administrative matter between the mobile subscriber and the service provider and causes no signalling on the radio interface.
In TS 24.010 the general aspects of the specification of supplementary services at the layer 3 radio interface are given.
3GPP TS 24.080 specifies the formats and coding for the supplementary services.
Definitions and descriptions of supplementary services are given in TS 22.004 and 3GPP TS 22.08x and 3GPP TS 22.09x series. TS 22.024 and 02.86 are related to the charging supplementary services.
Technical realization of supplementary services is described in TS 23.011 and 3GPP TS 23.08x and 3GPP TS 23.09x series. TS 23.086 is related to the charging supplementary services.
The procedures for Call Control, Mobility Management and Radio Resource management at the layer 3 radio interface are defined in TS 24.007 and TS 24.008.
The following supplementary services belong to the charging supplementary services and are described in the present document:
  • Advice of Charge (Information) (AoCI) (clause 1);
  • Advice of Charge (Charging) (AoCC) (clause 2).

0.2  AbbreviationsWord‑p. 6
Abbreviations used in the present document are listed in TR 21.905.

1  Advice of Charge (Information) (AoCI)

1.1  Normal operation with successful outcome

On every successful request for an applicable telecommunications service, the served Mobile Station (MS) will be provided with charging information.
The network sends the Charge Advice Information (CAI) to the MS according to TS 22.024, TS 22.086 and TS 23.086. 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.
Up

1.1.1  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.

1.1.2  MS originated callWord‑p. 7
For an MS originated call, charging information is transferred to the MS as shown in Figure 1.1. The charging information is acknowledged in a FACILITY message only if the MS supports the AoCI functionality specified in TS 22.024 and TS 22.086. AoCI refers to the Advice of Charge (Information) service.

1.1.3  MS terminated call

For an MS terminated call, where required, charging information is transferred to the MS as shown in Figure 1.2. The charging information is acknowledged only if the MS supports the AoCI functionality specified in TS 22.024 and TS 22.086.

1.1.4  Change of charging information

To inform the MS of a change in charging information the procedure of Figure 1.3 is performed. The charging information is acknowledged only if the MS supports the AoCI functionality specified in TS 22.024 and TS 22.086.

1.2  Normal operation with unsuccessful outcomeWord‑p. 8
No signalling is performed by the network if a MS fails to acknowledge receipt of charging Information.

1.3  Activation, deactivation and invocation

Activation, deactivation and invocation of the Advice of Charge (Information) supplementary service are not applicable.

1.4  Interrogation, registration and erasure

Interrogation, registration and erasure of the Advice of Charge (Information) supplementary service are not applicable.

2  Advice of Charge (Charging) (AoCC)

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 TS 22.024, TS 22.086 and TS 23.086. 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.
Up

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 TS 22.024 and TS 22.086. AoCC refers to the Advice of Charge (Charging) service.

2.1.3  MS terminated callWord‑p. 9
For an MS terminated call, where required, charging information is transferred to the MS as shown in Figure 2.2. The charging information is acknowledged only if the MS supports the AoCC functionality specified in TS 22.024 and TS 22.086.

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 TS 22.024 and TS 22.086.

2.2  Normal operation with unsuccessful outcomeWord‑p. 10
If timer T(AoC) (see TS 23.086) expires before the Charge Advice Information is acknowledged, the network shall release the call. The MS and network shall act in accordance with TS 24.008 network initiated call clearing procedures (see Figure 2.4).

2.3  Accumulated Call Meter is equal to or greater than ACMmax

If the change stored in the Accumulated Call Meter (ACM) is equal to or greater than the maximum value specified by ACMmax, then the MS shall initiate call clearing giving a specific cause value for this situation as indicated in Figure 2.5.
