Embodiment 1

[0074] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a voice quality assessment method according to the present invention, which may specifically include the following steps:

[0075] Step 101, when receiving a service establishment request sent by a mobile terminal, determine the service type corresponding to the service establishment request.

[0076] The embodiment of the present invention is applicable to the evaluation of the voice quality of the LTE (Long Term Evolution) network.

[0077] In an LTE network, when a mobile terminal sends a service establishment request to a base station eNodeB, it often carries a service level, and different service levels correspond to different service types. In practical applications, the core network determines the service type through the service level and configuration information, so as to deliver the service type to the base station.

[0078] Specifically, the service type may be confirmed according...

Embodiment 2

[0090] refer to figure 2 , shows a flow chart of the steps of Embodiment 2 of a voice quality assessment method according to the present invention, which may specifically include the following steps:

[0091] Step 201, when receiving a service establishment request sent by a mobile terminal, determine the service type corresponding to the service establishment request.

[0092] For this step, reference may be made to the detailed description of step 101, which will not be repeated here.

[0093] Step 202, if the service type is either voice or video, obtain the UDP port number.

[0094] For this step, reference may be made to the detailed description of step 102, which will not be repeated here.

[0095] Step 203: Count the packet loss rates of the Real-time Transport Protocol RTP packets and the Real-time Transport Control Protocol RTCP packets respectively according to the UDP port number.

[0096] In practical applications, since different UDP ports are used for transmi...

Embodiment 3

[0145] refer to image 3 , showing a structural block diagram of Embodiment 3 of a device for evaluating voice quality according to the present invention, which may specifically include the following modules:

[0146] A service type judging module 301, configured to judge the service type corresponding to the service establishment request when receiving the service establishment request sent by the mobile terminal;

[0147] Packet loss rate statistics module 302, for if described business type is any one in voice or video, then count respectively the packet loss rate of the real-time transport protocol RTP packet and the real-time transport control protocol RTCP packet that described mobile terminal sends;

[0148] A speech quality evaluation module 303, configured to evaluate the speech quality according to the packet loss rate of the RTP packet and the RTCP packet.

[0149] In the embodiment of the present invention, when the service establishment request sent by the mobile...

Abstract

Embodiments of the present invention provide a voice quality evaluation method and device, which relate to the technical field of communications. The method includes: when receiving a service establishment request sent by a mobile terminal, judging the service type corresponding to the service establishment request; The packet loss rate of the real-time transport protocol RTP packet and the real-time transport control protocol RTCP packet; evaluate the voice quality according to the packet loss rate of the RTP packet and the RTCP packet. This solves the problem that multiple MOS boxes need to be provided when evaluating the voice quality of multiple mobile terminals, and the problem of high evaluation cost is achieved, and the beneficial effect of reducing the evaluation cost is obtained.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a voice quality evaluation method and device. Background technique [0002] In an LTE (Long Term Evolution, Long Term Evolution) network, a voice service is an important service, making the assessment of voice quality an important indicator of the LTE network. [0003] In the prior art, the evaluation of the voice quality is realized through a MOS (Mean Opinion Score, average opinion scoring) box. Specifically, connect the mobile terminal to the MOS box, collect the voice after passing through the LTE network, and compare it with the original voice collected by the MOS box, so as to obtain a comprehensive score of voice quality. [0004] However, when multiple mobile terminals are used to evaluate the voice quality, multiple MOS boxes need to be provided, and the cost evaluation is relatively high. Contents of the invention [0005] In view of the above problems, the p...
