Abstract

A method for implementing a ring back tone, including: receiving, by a first Service Control Point, an intelligent service request triggered by a Service Switching Point, based on a call of a calling party; obtaining personal ring back tone information of a called party and/or group ring back tone information of a group, which the called party belongs to; acquiring first ring back tone information according to the personal ring back tone information and/or the group ring back tone information delivering a connect message containing the first ring back tone information to the Service Switching Point the connect message being used to instruct the Service Switching Point to connect the call to an Advanced Intelligent Peripheral for playing the ring back tone to the calling party according to the first ring back tone information.

Claims

1-11. -11. (canceled)

12. A method for implementing a ring back tone, comprising:

receiving, by a first Service Control Point, an intelligent service request triggered by a Service Switching Point, based on a call of a calling party;

obtaining personal ring back tone information of a called party and/or group ring back tone information of a group which the called party belongs to;

acquiring first ring back tone information according to the personal ring back tone information and/or the group ring back tone information;

delivering a connect message containing the first ring back tone information to the Service Switching Point the connect message being used to instruct the Service Switching Point to connect the call to an Advanced Intelligent Peripheral for playing the ring back tone to the calling party according to the first ring back tone information.

13. The method according to claim 12, wherein the personal ring back tone information and the group ring back tone information are stored in the first Service Control Point.

14. The method according to claim 12, wherein the group ring back tone information is stored in the first Service Control Point, the personal ring back tone information is stored in a second Service Control Point, and the second Service Control Point synchronizes the personal ring back tone information to the first Service Control Point.

15. The method according to claim 12, wherein the group ring back tone information is stored in the first Service Control Point, the personal ring back tone information is stored in a second Service Control Point, and the first Service Control Point sends a query request to the second Service Control Point to obtain the personal ring back tone information.

16. The method according to claim 12, wherein the first ring back tone information is acquired according to a preset ring back tone priority between the personal ring back tone information and the group ring back tone information.

17. The method according to claim 16, wherein the ring back tone priority is preset according to at least one of a time interval, a calling number and a called number.

18. A system for providing a ring back tone, comprising:

a Service Switching Point, configured to trigger an intelligent service request to a first Service Control Point based on a call of a calling party;

the first Service Control Point, configured to receive the intelligent service request triggered by the Service Switching Point, obtain personal ring back tone information of a called party and/or group ring back tone information of a group which the called party belongs to, acquire first ring back tone information according to the personal ring back tone information and/or the group ring back tone information, deliver a connect message containing the first ring back tone information to the Service Switching Point, the connect message being used to instruct the Service Switching Point to connect the call to an Advanced Intelligent Peripheral;

the Advanced Intelligent Peripheral, configured to play the ring back tone to the calling party according to the first ring back tone information.

19. The system according to claim 18, wherein the first Service Control Point is further configured to store the personal ring back tone information and the group ring back tone information.

20. The system according to claim 18, further comprising a second Service Control Point configured to store the personal ring back tone information, wherein the first Service Control Point is further configured to store the group ring back tone information, and the second Service Control Point synchronizes the personal ring back tone information to the first Service Control Point.

21. The system according to claim 18, further comprising a second Service Control Point configured to store the personal ring back tone information, wherein the first Service Control Point is further configured to store the group ring back tone information, and the first Service Control Point sends a query request to the second Service Control Point to obtain the personal ring back tone information.

22. The system according to claim 18, wherein the Advanced Intelligent Peripheral further comprises a first Advanced Intelligent Peripheral configured to play a personal ring back tone and a second Advanced Intelligent Peripheral configured to play a group ring back tone, the first and the second Advanced Intelligent Peripherals being independent of each other.

23. The system according to claim 18, wherein the first ring back tone information is acquired according to a preset ring back tone priority between the personal ring back tone information and the group ring back tone information.

24. A service control device, comprising:

a receiving unit, configured to receive an intelligent service request triggered by a Service Switching Point based on a call of a calling party;

an obtaining unit, configured to obtain personal ring back tone information of a called party and/or group ring back tone information of a group to which the called party belongs, based on the call;

an acquiring unit, configured to acquire first ring back tone information according to the personal ring back tone information and/or the group ring back tone information;

a delivering unit, configured to deliver a connect message containing the first ring back tone information to the Service Switching Point, the connect message being used to instruct the Service Switching Point to connect the call to an Advanced Intelligent Peripheral for playing the ring back tone to the calling party according to the first ring back tone information.

25. The device according to claim 24, further comprising a priority storage unit configured to store ring back tone priority information customized by the called party, wherein the acquiring unit is configured to acquire the first ring back tone information based on the ring back tone priority information stored in the priority storage unit.

26. The device according to claim 24, further comprising a storage unit configured to store the personal ring back tone information.

27. The device according to claim 24, further comprising a storage unit configured to store the personal ring back tone information and the group ring back tone information.
