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).
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.
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.
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.
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.
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.
No signalling is performed by the network if a MS fails to acknowledge receipt of charging Information.
Activation, deactivation and invocation of the Advice of Charge (Information) supplementary service are not applicable.
Interrogation, registration and erasure of the Advice of Charge (Information) supplementary service are not applicable.
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.
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.
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.
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.
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.
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).
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.
Activation, deactivation and invocation of the Advice of Charge (Charging) supplementary service are not applicable.
Interrogation, registration and erasure of the Advice of Charge (Charging) supplementary service are not applicable.
