A method for identifying the user's on-hook state based on the user's color ring back tone information
A technology for on-hook status and information identification, applied in the field of communication, can solve the problems that the call center cannot obtain the real status of the called user, there is no unified standard for the definition of error codes, and the reasons for signaling on-hook are inconsistent, so as to achieve good applicability and scalability. performance, improve accuracy, and improve the effect of effective connection rate

Problems solved by technology
[0003] The existing problem is that the on-hook code in the signaling is often inconsistent with the real on-hook reason, that is, the on-hook code is inaccurate. There is no uniform standard for the definition of error codes
In the end, the error code in the signaling is inconsistent with the real cause of the hangup
[0004] The direct problem caused by the inaccurate hang-up code is that the call center cannot obtain the real status of the called user, which will seriously affect the later statistics and analysis results in the scenarios of AI outbound calls and automatic outbound calls

Embodiment Construction
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0037] see figure 1 , the present invention provides a technical solution: a method for identifying the user's on-hook state based on the user's CRBT information, and the specific steps are as follows:
[0038] S1. Collect a large number of audio files of user hang-up ring tones such as empty numbers, shutdown, shutdown, user rejection, temporary inability to connect, wrong number, etc., and mark the corresponding user hang-up reasons;
[0039] Step S1 specificall...

The present invention obtains the user state through the color ring tone in the media, which can ensure that the call center can obtain the reliable user on-hook state, obtain the correct on-hook state, and provide reliable data in scenarios such as automatic outbound calls and AI outbound calls , so that the continuous statistics and analysis can be carried out normally, and at the same time save a lot of manpower for manual marking, and the error code will only be returned after the CRBT is played. By identifying the CRBT, we can obtain the user's on-hook status in advance, and also Improve the efficiency of the system.
Description
technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for identifying a user's on-hook state based on the user's CRBT information. Background technique [0002] The existing call is divided into two parts, one part is signaling and the other part is media; signaling is used to control the call process, including steps such as call initiation, media negotiation, connection and hang-up; media is used to establish media transmission The channel is for media transmission, and the media includes two types, color ring and call. In a normal call, the phone user can judge whether the called user is busy or turned off or other according to the color ring. In the call center, the on-hook code in the signaling is generally used to judge the on-hook state of the called user. [0003] The existing problem is that the on-hook code in the signaling is often inconsistent with the real on-hook reason, that is, the on-hook...
