C.1 AoC Information mapping to CAI element

32.2803GPPAdvice of Charge (AoC) serviceCharging managementRelease 17Telecommunication managementTS

Herby is a conceptual mapping of the CAI Element to the AoC Information.

The mapping is done by using 3 Rate Elements:

Rate Element 1 – Depicts the initial cost in the AoC

Rate Element 2 – Depicts the time related AoC

Rate Element 3 – Depicts the volume related AoC

Table C.1.1:

CAI parameter	Mapping guidance
e1 – Units per interval	Cost_Value in a Rate Element(2) with Unit-Type = TIME;
e2 – Seconds/time interval	Unit_Value in Rate Element(2)
e3 – Scaling Factor	Scale_Factor
e4 – Unit increment	Cost_Value in a Rate Element(1) with Unit-Type = TIME
e5 – Units per data interval	Cost_Value in a Rate Element(3) with Unit-Type = TOTAL-OCTETS;
e6 – Segments/data interval	Unit_Value in Rate Element(3)
e7 – Initial secs/t interval	Unit_Threshold in Rate Element(1)

When a service is known to be provided by CAMEL, the AoC function shall use a mapable construct of the AoC Information.
