Abstract

A method and system for charging secondary traffic in a radio telecommunications network. The system includes a mobile switching center (MSC) for delivering a call in the radio telecommunications network and a radio network control Ler (RNC) for controlling the radio telecommunications network. The MSC includes a charging unit for calculating a primary traffic charge, a secondary traffic charge, and a total charge for a call. Additionally, the RNC employs frame structure counters to assess the amount of secondary traffic carried in the call. The method begins by the frame structure counters assessing an amount of secondary traffic carried in a call in the radio telecommunications network. The charging unit then calculates a charge for the secondary traffic carried by the call.

Claims

1. A traffic charging system in a radio telecommunications network comprising:

means for multiplexing both primary traffic at a first bit rate and secondary traffic at a second bit rate in a single call;

means for calculating a charge for said primary traffic in said call at a primary traffic charge rate; and

means for calculating a charge for said secondary traffic in said call at a secondary traffic charge rate.

2. The traffic charging system of claim 1 further comprising means for calculating a total charge for the call by adding together the charge for primary traffic and the charge for secondary traffic.

3. The traffic charging system of claim 2 wherein said means for calculating a charge for the secondary traffic in the call includes:

a secondary traffic assessor which determines whether any secondary traffic has been carried by said call; and

a plurality of frame structure counters which determine an amount of traffic in said call that is secondary traffic.

4. The traffic charging system of claim 3 wherein said means for calculating a charge for said secondary traffic in said call includes a secondary traffic toll device which applies the secondary traffic charge rate to said amount of traffic in said call that is secondary traffic in order to determine a charge for said secondary traffic in said call.

5. The traffic charging system of claim 4 wherein said means for calculating a charge for said primary traffic in said call includes a primary traffic toll device which applies the primary traffic charge rate to said amount of traffic in said call that is primary traffic in order to determine a charge for said primary traffic in said call.

6. The traffic charging system of claim 5 wherein said means for calculating a total charge for said call includes a charge rate processor that combines the charge for said primary traffic in said call and said charge for said secondary traffic in said call.

7. In a radio telecommunications network in which an amount of primary traffic at a first bit rate and an amount of secondary traffic at a second bit rate are multiplexed in a single call, a system for charging for the secondary traffic, said system comprising:

a mobile switching center (MSC) for delivering said call in said radio telecommunications network;

a counting device for assessing the amount of said secondary traffic carried by said call separately from the amount of primary traffic; and

a charging unit for calculating a charge for the secondary traffic from said amount of said secondary traffic assessed by said counting device.

8. The system of claim 7 wherein said counting device includes a plurality of frame structure counters for assessing said amount of said secondary traffic.

9. The system of claim 8 wherein said counting device includes a secondary traffic assessor for determining whether any secondary traffic has been carried by said call.

10. The system of claim 7 wherein said charging unit includes:

a primary traffic toll device which applies a primary traffic charge rate to the amount of primary traffic of said call; and

a secondary traffic toll device which applies a secondary traffic charge rate to said amount of secondary traffic.

11. The system of claim 10 wherein said charging unit includes a charge rate processor for calculating a total charge for said call.

12. In a radio telecommunications network having a radio network controller (RNC) and a charging unit, a method of charging for secondary traffic carried by a call which carries an amount of primary traffic at a first bit rate and an amount of secondary traffic at a second bit rate, said method comprising the steps of:

multiplexing the primary traffic and the secondary traffic in a single call;

assessing, by said RNC, the amount of said secondary traffic carried by said call separately from the amount of primary traffic; and

determining, in said charging unit, a charge for said secondary traffic carried by said call.

13. The method of claim 12 further comprising, before the step of assessing the amount of said secondary traffic, the steps of:

receiving said call in a mobile switching center (MSC); and

transmitting said call in a frame structure from said MSC to said RNC.

14. The method of claim 13 further comprising, after the step of assessing the amount of said secondary traffic, the step of sending said amount of said secondary traffic from said RNC to said charging unit.

15. The method of claim 14 wherein said step of determining a charge for said call by said charging unit includes determining a charge for said secondary traffic by a secondary traffic toll device located in said charging unit.

16. The method of claim 15 wherein said step of assessing an amount of said secondary traffic services includes assessing said amount of said secondary traffic by a frame structure counter to determine said amount of secondary traffic of each frame structure.

17. The method of claim 12 further comprising, after the step of assessing the amount of said secondary traffic, the step of determining by said RNC that said secondary traffic has been used in said call.

18. The method of claim 17 further comprising, after the step of determining a charge for said secondary traffic by said charging unit, the step of calculating a total charge for said call by said charging unit.

19. The method of claim 18 wherein said step of calculating a total charge for said call includes calculating a total charge for said call by a charge rate processor located in said charging unit.
