This method has "speech path detour", which not only occupies additional speech path relay resources during the call, but also depends on the stability of the ring back tone service center
Another user can only have one service subscription / trigger, and there is a conflict between the CRBT service and other intelligent network services

The related method for color-ring business in CDMA network comprises: for color-ring user, setting a trigger T1 with assigned address as color-ring system on HLR; when the calling dials the user, the initiation-calling MSC obtains T1 from HLR to trigger the color-ring business, the color-ring system indicates the MSC to follow the calling; the MSC first follows the calling to the called MSC, thensucceeds the calling to color-ring system when receiving message indicated the called on free from service MSC; the color-ring system begins displaying color-ring; the initiation-calling MSC turns onthe phone channel between the calling and color-ring system, the calling obtains the ring; when the called changes its free state, the initiation-calling MSC breaks the channel and completes the business. This invention is simple for CDMA network.
Description
A method for implementing code division multiple access network color ring service technical field The invention relates to a method for realizing CDMA network color ring service. Background technique The CRBT service (personalized ring-back tone service) refers to allowing the caller to listen to the CRBT when the called user is free. Because of its prominent personalized features and obvious enhancement of hearing experience, it has been well developed in China and even East Asian telecom markets. At present, the networking of various networks is diversified, and the capabilities of mobile switching centers of various equipment manufacturers are also different. Therefore, the ring back tone function needs to be provided in combination with specific networking and capabilities of mobile switching centers. In the prior art, there are mainly two ways to realize the color ring tone. One is to add the "CRBT service" user attribute data in the mobile switching center / HLR, an...
