Abstract

A method and system for charging for services in a communication system comprises a charging entity and at least two connection support entities for providing resources to support a connection in the communication system. Various steps include detecting initiation of a connection by the connection support entities; generating a charging identity for identifying the connection; determining a first charge for supporting the connection by the first connection support entity; determining a second charge for the support of the connection by the second connection support entity; transmitting a first charging message from the first connection support entity to the charging entity, the message specifying the first charge and including the charging identity; and transmitting a second charging message from the second connection support entity to the charging entity, the second charging message specifying the second charge and including the charging identity.

Claims

1. A method comprising:

receiving at a communications network charging entity a charging identity identifying a connection initiated by a communication terminal, the connection being supported by a first connection support entity and a second connection support entity;

receiving at the communications network charging entity a first charging message from the first connection support entity, the first charging message specifying a first tariff and including the charging identity;

receiving at the communications network charging entity a second charging message from the second connection support entity, the second charging message specifying a second tariff and including the charging identity;

storing in the communications network charging entity the first tariff and the second tariff;

the communications network charging entity performing the steps of

determining according to the first stored tariff a first charge for the support of the connection by the first connection support entity;

determining according to the second stored tariff a second charge for the support of the connection by the second connection support entity; and

periodically estimating a charge for the connection according to the first and second charges and comparing the estimated charge with the balance of an account to which the connection is to be charged; and

dividing a total estimate charge into at least two portions and comparing one of those portions to a first account and the second of those portions to a second account.

2. The method as claimed in claim 1, wherein at least one of the first and second charges is determined based on the duration of the connection.

3. The method as claimed in claim 1, wherein at least one of the first and second charges is determined based on the amount of data transmitted during the connection.

4. The method as claimed in claim 3, wherein the connection supports the carrying of data in packet form and at least one of the first and second charges is determined based on the number of packets transmitted during the connection.

5. The method as claimed in claim 1, wherein at least one of the first and second charges is of a fixed value.

6. The method as claimed in claim 1, wherein each of the first and second connection support entities has a unique identity.

7. The method as claimed in claim 6, wherein each of the connection support entities maintains a count of the charging identities it has generated, and the charging identity is formed by combining the unique identity of the entity that generates the charging identity and a next sequential number in the count maintained by that entity.

8. The method as claimed in claim 6, comprising the steps of:

transmitting from the first connection support entity to the communications network charging entity the unique identity of the first connection support entity; and

transmitting from the second connection support entity to the communications network charging entity the unique identity of the second connection support entity.

9. The method as claimed in claim 1, comprising the step of transmitting the charging identity from the first connection support entity to the second connection support entity.

10. The method as claimed in claim 1, wherein the first account is associated with a terminal that initiated the connection.

11. The method as claimed in claim 10, wherein the second account is associated with another terminal to which the terminal that initiated the connection has been connected by means of the connection.

12. The method as claimed in claim 10, wherein the second account is unassociated with another terminal to which the terminal that initiated the connection has been connected by means of the connection.

13. The method of claim 1, wherein the first connection support entity is operated by a first system operator and the second connection support entity is operated by a second system operator different from the first system operator.

14. A method comprising:

at a connection support entity in a communication system, detecting initiation of a connection with a communication terminal;

generating at the connection support entity a unique charging identity for identifying the connection to another connection support entity located in a different network and to a communications network charging entity, wherein the unique charging identity is also assigned for use by the another connection support entity in forming a combined charge for the connection;

making available the charging identity to the another connection support entity and to the communications network charging entity;

determining according to a tariff stored in the connection support entity a charge for supporting the connection by the connection support entity;

transmitting a charging message to the communications network charging entity, the charging message specifying the charge and including the charging identity; and

periodically estimating a charge for the connection according to a first charge received from the connection support entity and a second charge received from the another connection support entity and comparing the estimated charge with a balance of an account.

15. The method as claimed in claim 14, wherein the charge is determined based on the duration of the connection.

16. The method as claimed in claim 14, wherein the charge is determined based on the amount of data transmitted during the connection.

17. The method as claimed in claim 16, wherein the connection supports a carrying of data in packet form and the charge is determined based on the number of packets transmitted during the connection.

18. The method as claimed in claim 14, wherein the charge is of a fixed value.

19. The method as claimed in claim 14, wherein the connection support entity has a unique identity.

20. The method as claimed in claim 19, further comprising maintaining in the connection support entity a count of the charging identities it has generated, and the charging identity is formed by combining the unique identity of the connection support entity and a next sequential number in the count.

21. The method as claimed in claim 14, further comprising transmitting the charging identity from the connection support entity to the another connection support entity.

22. The method of claim 14, wherein the first connection support entity corresponds to a first operator network and the second connection support entity corresponds to a second operator network different from the first operator network.

23. A method comprising:

at a communications network charging entity, receiving a charging identity from a first connection support entity that identifies a connection to a communication terminal, the connection supported by the first connection support entity and a second connection support entity;

receiving a first charging message from the first connection support entity, the message specifying a first charge and including the charging identity;

receiving a second charging message from the second connection support entity, the second charging message specifying a second charge and including the charging identity;

adding the first and second charging messages to a transaction to form a total value for the transaction;

debiting the total value of the transaction from an account indicated in the first or second charging message;
