Abstract

The present invention relates to a method and arrangements for determining charging related to a data bit transfer session from a traffic source (209) to a client (213), said bit transfer session involving bit transfer over a wireless communications link (214f) under the control of a radio resource managing unit (204). According to the method of the present invention the radio resource managing unit (204) sends information regarding the bandwidth on the wireless link that the bit transfer session currently is allowed to use to a charging logic (212). This bandwidth information from the radio resource managing unit (204) is used by the charging logic (212) to determine the charging related to the bit transfer session. Thereby a fair charging of the session may be achieved, which is adapted to the quality of service actually obtained by the end-user for the session.

Claims

1. A method for determining charging related to a data bit transfer session, said bit transfer session involving bit transfer over a wireless communications link under the control of a radio resource managing unit, which radio resource managing unit dynamically determines the bandwidth on the wireless link available to the bit transfer session the method comprising the steps of:

a charging logic receiving information from the radio resource managing unit about the bandwidth on the wireless link that the bit transfer session is allowed to use; and

said charging logic determining the charging related to the bit transfer session based on said received information from the radio resource managing unit.

2. The method for determining charging according to claim 1 further comprising

the charging logic receiving said information from the radio resource managing unit each time the bandwidth on the wireless link available to the bit transfer session has changed.

3. The method for determining charging according to claim 1 further comprising

the charging logic receiving said information from the radio resource managing unit at predetermined intervals.

4. The method for determining charging according to claim 1 further comprising

the charging logic receiving said information from the radio resource managing unit each time the bandwidth on the wireless link available to the bit transfer session has changed and the bandwidth change has been applied to the session for a predetermined period of time.

5. The method for determining charging according to claim 1 further comprising the charging logic receiving said information from the radio resource managing unit at intervals which depend on the service type of the bit transfer session.

6. The method for determining charging according claim 1 further comprising

the charging logic receiving said information from the radio resource managing unit via an application server which relays said information from the radio resource managing unit to the charging logic.

7. The method for determining charging according to claim 1 further comprising

the charging logic receiving said information from the radio resource managing unit via a mobile proxy which relays said information from the radio resource managing unit to the charging logic.

8. The method for determining charging according to claim 1 further comprising

the charging logic adapting the charging related to the bit transfer session such that the session is charged according to charging rates associated with a first charging class when the bandwidth on the wireless link available to the bit transfer session is within a first predetermined interval and according to charging rates associated with a second charging class when the bandwidth on the wireless link available to the bit transfer session is within a second predetermined interval.

9. The method for determining charging according to claim 1 further comprising

the charging logic determining that the charging related to the bit transfer session should be zero when the bandwidth on the wireless link available to the bit transfer session is below a predetermined threshold level.

10. The method for determining charging according to claim 1 further comprising

the charging logic adapting the charging related to the bit transfer session based on said received information from the radio resource managing unit such that the impact of said received information from the radio resource managing unit on the charging of the bit transfer session depends on the type of service of the bit transfer session.
