Method for providing ring back tone

Abstract

The present invention discloses providing ringing back tone method. Said method includes calling switchboard judging whether called user idleness, if it is then transmitting current calling and called subscriber number to service switching point; said service switching point detecting whether said called number carried with ringing back tone accessing code, if it is then transmitting said calling and called subscriber number to service control point; service control point according to said called subscriber number determining attributive number segment, in different ringing back tone service platform selecting said number segment correspondent ringing back tone service platform; said selected ringing back tone service platform according to said called subscriber number providing said called subscriber number correspondent ringing back tone to calling user. The present invention realizes simultaneously accessing different equipment maker provided ringing back tone service platform in same operation network, to make different number segment user capable of obtaining difference service.

Description

technical field

[0001] The present invention relates to the technical field of ring back tone, and more specifically, the present invention relates to a method for providing ring back tone. Background technique

[0002] The ring back tone service is a service that allows the phone user to customize the ring back tone. It is when the calling party makes a call to the called party, and before the called terminal rings and picks up the phone, the calling user hears the caller, called or Personalized ring back tone customized by group users.

[0003] In addition, ring back tones can be divided into different types according to different customized users: calling ring back tones, called ring back tones, and group ring back tones. Among them, calling ring back tones are customized by calling users; called ring back tones It is customized by the called user; the group ringback tone is customized by the group customer.

[0004] The industry usually refers to the personalized ring ...
