A volte user subjective perception guarantee method and system

Abstract

The invention discloses a method for guaranteeing subjective perception of VoLTE users. The method includes: obtaining the user's real objective perception service index and the voice media flow objective perception service index of each dial test task; obtaining each dial test task and the result of the dial test task Combining the objective perception service indicators of the voice media stream of the dialing test task, calculating the impairment parameters of each audio coding format; according to the real objective perception service indicators of the user, combined with the corresponding impairment parameters of the audio encoding format, obtaining And save the user's subjective perception damage reduction value; according to the user's complaint information, add a complaint label to the user's subjective perception damage reduction value, count the number of different complaints, and obtain the relationship between the number of complaints and the corresponding subjective perception damage reduction value Curve; set the tolerance value of user complaints, obtain the threshold of subjective perception damage reduction value corresponding to the tolerance value of user complaints according to the relationship curve, if the user’s subjective perception damage reduction value is greater than the threshold, generate user subjective Perceived impairment warning. The invention also discloses a VoLTE user subjective perception protection device.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a VoLTE user subjective perception assurance technology. Background technique [0002] At present, the guarantee of telecom voice services has realized the monitoring and management of the network equipment level, the service level, and the level of user objective perception of service quality, but the monitoring and guarantee of individual user subjective perception of service quality has not yet been realized. With the widespread use of VoLTE services, currently VoLTE service guarantees have formulated service indicators at the network equipment level, service level, and user objective service quality level, such as device CPU load, connection rate, and RTP packet loss rate, based on TMF-related methodologies. , is about to enter the stage of IT system implementation, but there is still a lack of feasible solutions in terms of guaranteeing the subjective perception o...

[0002] At present, the guarantee of telecom voice services has realized the monitoring and management of the network equipment level, the service level, and the user's objective perception of service quality, but the monitoring and guarantee of the subjective perception of individual user's service quality has not yet been realized.

With the widespread use of VoLTE services, currently VoLTE service guarantees have formulated service indicators at the network equipment level, service level, and user objective service quality level, such as device CPU load, connection rate, and RTP packet loss rate, based on TMF-related methodologies. , is about to enter the stage of IT system implementation, but there is still a lack of feasible solutions in terms of guaranteeing the subjective perception of service quality for individual users

[0003] In the prior art, there is a solution based on VoIP voice quality assessment, but this solution uses the user's original voice data, so it can only be used for dial-up testing, and cannot guarantee the subjective perception of service quality for all users.
