Charging for an IP based communication system
View Patent ↗There is disclosed a method for charging for services in a communication system supporting a Diameter IP protocol, comprising defining at least one attribute value pair to define sponsorship information.
1. A method comprising:
receiving a request to establish an internet protocol (IP) session from a user of a communication system supporting a diameter IP protocol;
initiating an account with an account controller of the system, wherein the initiating comprises transferring sponsorship information to a charging system from an application server, said sponsorship information being provided to enable shared charging, the charging system being responsible for monitoring of the account;
establishing the IP session; and
initiating the monitoring of the account responsive to an account request message from said account controller to obtain a final tariff.
2. A method according to claim 1 wherein the account is initiated responsive to an account request message.
3. A method according to claim 1 wherein the sponsorship information is defined by at least one attribute value pair.
4. A method according to claim 3 further comprising providing an attribute value pair defining shared charging information.
5. A method according to claim 3 further comprising providing an attribute value pair defining shared percentage information.
6. A method according to claim 3 further comprising providing an attribute value pair defining shared amount information.
7. A method according to claim 3 further comprising providing an attribute value pair defining a sponsor identity.
8. A communication system comprising:
a control function configured to initiate an internet protocol (IP) session for a user of the system, wherein the system supports a diameter IP protocol;
an application server configured to provide an application for a user of the system in an IP session;
an account controller configured to initiate an account;
a charging unit configured to charge an IP session for a user, wherein the charging unit is configured to receive sponsorship information to enable shared charging from the application server on initiation of the account, and is configured to monitor the account responsive to an account request message from said control function to obtain a final tariff.
9. A communication system according to claim 8 wherein the control function comprises a serving call state control function.
10. A communication system according to claim 8 wherein the charging unit comprises an on-line charging function and an off-line charging function.
11. A communication system according to claim 8 , wherein the charging is initiated on the basis of a diameter IP communication between the call control function and the charging unit.
12. A communication system according to claim 8 , wherein shared charging information is communicated to the charging unit from the application function on the basis of a diameter IP communication.
13. A communication system according to claim 8 , wherein the charging unit is configured to monitor the call session charges responsive to a diameter IP communication from the call control function.
14. A communication system according to claim 8 wherein the diameter protocol is configured to define at least one attribute value pair to define sponsorship information.
15. A communication system according to claim 14 wherein the attribute value pair is configured to define shared charging information.
16. A communication system according to claim 14 wherein the attribute value pair is configured to define shared percentage information.
17. A communication system according to claim 14 wherein the attribute value pair is configured to define shared amount information.
18. A communication system according to claim 14 wherein the attribute value pair is configured to define a sponsor identity.
19. A diameter internet protocol (IP) configured to define at least one attribute value pair to define sponsorship information.
20. A diameter IP protocol according to claim 19 wherein the sponsorship information is provided to enable shared charging.
21. An apparatus comprising:
a receiver configured to receive a request to establish an internet protocol (IP) session from a user of a communication system supporting a diameter IP protocol;
an initiating unit configured to initiate an account with an account controller of the system, wherein the initiating comprises transferring sponsorship information to enable shared charging from the application to a charging system, the charging system being responsible for monitoring of the account; and
an establishing unit configured to establish the IP session and to send an account request message to obtain a final tariff to a charging system, thereby to initiate the monitoring of the account.
22. An apparatus comprising:
receiving means for receiving a request to establish an internet protocol (IP) session from a user of a communication system supporting a diameter IP protocol;
initiating means for initiating an account with an account controller of the system, wherein the initiating means comprises means for transferring sponsorship information to enable shared charging from an application server to a charging system, the charging system being responsible for monitoring of the account;
establishing means for establishing the IP session; and
sending means for sending an account request message to obtain a final tariff to a charging system, thereby to initiate the monitoring of the account.
