Abstract

The invention relates to a method for monitoring and controlling a number of available decentralized IP budgets of a subscriber in a packet-based communications network during an online assessment of charges for data transmissions. According to the invention, the number of available IP budgets are each allocated in a data flow-specific manner to a data flow in a context that can be assigned to the subscriber, and a higher-order control function is provided in a network node of the communications network. Said higher-order control function charges the data flow-specific IP budget according to a resource use of a data flow based on charge assessment specifications issued by a charge assessing computer during a resource use of the data flow in a context that can be assigned to the subscriber, and effects a partial or complete transmission of the IP budget between selected data flows in a case-related manner.

Claims

1. A method for monitoring and controlling a number of available decentralized IP budgets of a subscriber in a packet-based communications network during an online assessment of charges for data transmissions, comprising:

allocating a plurality of available IP budgets in a data-flow-specific manner to a data flow in a context that can be assigned to the subscriber;

providing a higher-order control function in a network node of the communications network, the control function charging the data-flow-specific IP budget according to a resource use of a data flow based on charge assessment specifications issued by a charge-assessing computer during a resource utilization of the data flow in a context that can be assigned to the subscriber; and

effecting a partial or complete transmission of the IP budget between selected data flows on a case-by-case basis, whereby the control function effects a reallocation or transfer of the IP budget according to the specifications of the charge-assessing computer.

2. The method according to claim 1, wherein when a data flow is added or removed, the charge assessing computer or the control function requests a return of allocated IP budgets according to the charge assessment specifications of the charge-assessing computer and reallocates the IP budgets.

3. The method according to claim 1, wherein the charge assessing computer or the control function requests a return of allocated IP budgets at a point in time specified by the charge-assessing computer according to the charge assessment specifications of the charge-assessing computer, and reallocates the IP budgets.

4. The method according to claim 1, wherein some or all of the data-flow-specific IP budget of a first data flow is transferred by the control unit according to the charge assessment specifications of the charge assessing computer to a second data flow if a data-flow-specific IP budget allocated to the second data flow reaches a threshold value or is completely used up.

5. The method according to claim 1, wherein some or all of the data-flow-specific IP budget of a first data flow is transferred by the control unit to a second data flow if the second data flow belongs to a context that can be allocated to an IP address of a same subscriber.

6. The method according to claim 1, wherein some or all of the data-flow-specific IP budget of the first data flow is transferred by the control unit to a second data flow if the second data flow belongs to a context that can be allocated to a same IP address of the subscriber.

7. The method according to claim 1, wherein some or all of the data-flow-specific IP budget of a first data flow is transferred by the control unit to a second data flow if the second data flow belongs to the same context as the first data flow.

8. The method according to claim 1, wherein the charge-assessing computer issues a transfer authorization, within the charge assessment specifications, between a first and a second data flow by marking the first and the second data flow with a common identifier.

9. The method according to claim 1, wherein a data-flow-specific weighting factor is specified by the charge-assessing computer for charge assessment of a data flow.

10. The method according to claim 9, wherein a data-flow-specific weighting factor is specified by the charge-assessing computer for charge assessment of a data flow by means of a table or pointer to a position in a table.

11. The method according to claim 1, wherein a GPRS network is used as the packet-based communications network.

12. The method according to claim 11, wherein the control function is located in a GGSN.

13. The method according to claim 1, wherein the control function requests a return of the IP budgets of all other data flows when a threshold value of a data-flow-specific IP budget of any data flow is reached, and transfers them to the charge assessing computer.

14. The method according to claim 1, wherein part of a data-flow-specific IP budget of a data flow terminated by the subscriber is transferred by the control function to one or more existing or new data flows.

15. The method according to claim 1, wherein when a new data flow is added by the control function according to the charge assessment specifications of the charge-assessing computer, at least part of the IP budget of at least one existing data flow is transferred to the new data flow.
