Abstract

The invention relates to the control of billing in a communications network. The objective is to accomplish a mechanism for minimizing credit losses caused by subscribers, while at the same time maintaining good performance of the system. A gateway receives service requests and filters out the requests for which the analysis performed indicates that a credit loss risk is involved. For these service requests an in-advance credit check is initiated. If the credit check indicates that the delivery is permissible, a reservation is made for the amount of money corresponding to the service price, i.e. the said sum is reserved in the subscriber account so that said sum cannot be used by another service request in the meantime. When the service has been delivered successfully, the reservation is confirmed and the said sum is debited from the balance of the subscriber account. Otherwise, the reservation is cancelled.

Claims

receiving a service request from a client, wherein the service request includes a subscriber identifier identifying a subscriber paying for the service and a service identifier identifying a content server;

analyzing, by a gateway, in response to receiving the service request from the client, whether a credit check is required prior to delivery of the service;

performing said credit check when the analyzing indicates that the credit check is required;

in response to a credit check, making a billing reservation for said subscriber and associating a monetary value with said billing reservation;

forwarding the service request to the content server;

initiating service delivery from the content server; and

billing the client according to the billing reservation in response to the service request being fulfilled and not billing according to the billing reservation in response to the service request not being fulfilled,

wherein the analyzing further comprises retrieving service profile data related to said service and subscriber profile data related to said subscriber and using said profile data to determine whether a credit check is required.

2. A method according to claim 1, wherein said analyzing includes selecting a payment method from a group of different payment methods.

using, in said group of different payment methods, at least one payment method that directly indicates that the credit check is not required;

assigning intermediate actions to each of said payment methods; and

in response to said analyzing, performing the intermediate actions assigned to the selected payment method, wherein the forwarding is performed in response to said intermediate actions.

4. A method according to claim 3, wherein the intermediate actions include contacting an external server.

5. A method according to claim 2, wherein the analyzing includes the selection of a first payment method in which the service is paid from an account with a pre-deposited money for the service.

6. A method according to claim 1, further comprising:

determining whether a client-confirmed contract concerning the service is required.

7. A method according to claim 6, further comprising:

negotiating said contract with the client.

8. A method according to claim 1, further comprising:

maintaining user-specific accounts in a billing server.

9. A method according to claim 8, wherein said credit checks are performed for service requests for which said first payment method is selected in the analyzing.

10. A method according to claim 8, wherein the maintaining further comprises maintaining a primary balance and a local balance for a subscriber-specific account, wherein the local balance is maintained in a first part of the billing server and the primary balance is maintained in a second part of the billing server, and the maintaining further comprises sending balance update messages between the first part and the second part of the billing server.

11. A method according to claim 10, wherein the local balance contains a cumulative sum of charges generated since the latest balance update between the first part and the second part of the billing server.

12. A method according to claim 10, further comprising:

transferring money from the primary balance to the local balance;

comparing the local balance to said monetary value; and

making said billing reservation on the basis of said comparison.

13. A method according to claim 10, further comprising:

controlling a frequency of said balance updates.

14. A method according to claim 13, wherein said controlling comprises generating trigger values indicating the moment to perform a next balance update.

15. An apparatus, comprising:

at least one processor; and

at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform;

receive a service request from a client, wherein the service request comprises a subscriber identifier identifying a subscriber paying for the service and a service identifier identifying a content server,

analyze, in response to receiving the service request from the client, whether a credit check is required prior to delivery of the service,

initiate sending of a credit check request and to receive a billing reservation identifier in response, wherein said identifier identifies a billing reservation that is associated with said subscriber and that indicates a price of the service,

retrieve service profile data related to said service and subscriber profile data related to said subscriber and use said profile data to determine whether a credit check is required, and

determine whether a separate billing server is to receive acknowledgement of service delivery.

16. An apparatus according to claim 15, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to receive acknowledgements of service delivery, and be responsive to said received acknowledgement.

17. An apparatus according to claim 15, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to initiate sending of an acknowledgement message containing said billing reservation identifier to the billing server.

18. An apparatus according to claim 15, wherein the apparatus is controllable from said billing server.

19. An apparatus according to claim 15, wherein said at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to select a payment method from a group of different payment methods.

20. A method comprising:

receiving a service request from a client, wherein the service request includes a subscriber identifier identifying a subscriber paying for the service and a service identifier identifying a content server;

analyzing, by a gateway, in response to receiving the service request from the client, whether a credit check is required prior to delivery of the service;

initiate sending of a credit check request to a billing server when the analyzing indicates that a credit check is needed;

receiving a billing reservation identifier in response to said credit check request, wherein said identifier identifies a billing reservation that is associated with said subscriber and that indicates the price of the service; and

determining whether a separate billing server is to receive acknowledgement of service delivery, wherein

the analyzing comprises retrieving service profile data related to said service and subscriber profile data related to said subscriber and using said profile data to determine whether a credit check is required.
