Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of optimization method and device of mobile radio communication voice quality.
Background technology
Mobile communication carrier is in operation stage, and the quality of service of whole network is the vital factor of competing between the operator, and the voice quality that mobile network provides for the user is the most important evaluation index of quality of service.And the wireless access way of mobile radio communication makes user's speech business quality have unreliability, has only accurate discovery mobile subscriber's voice quality problem, and the location influences the reason of voice quality, could effectively improve the voice quality of mobile communications network.
The mobile subscriber is using mobile communications network to carry out in the process of speech business, and phenomenons such as single-pass, no audio, call drop, noise appear in regular meeting, and noise comprises noise, metallic sound, the thorn power of hearing, bubble, utter long and high-pitched sounds etc.Single pass is the user on the phone, the other party can not hear one voice; dual barrier is the user on the phone, the two sides can not hear each other's voice; dropped calls is a user during a call, the network termination of the user's call ; murmur is a user during a call, there is the voice of non-user audio content; metallic sound is a user during a call there is a high frequency, very shrill voice of non-users, such as "cracking, cracking," "dth, dth" sound.Mobile communications network has very high call completing rate, response rate, coverage rate now; Very low cutting off rate, congestion ratio; The very short time delay that continues; Just represent network index very good, very normal, but the problem of above-mentioned voice quality accounts for suitable ratio, how finding, locate and solve these voice quality problems is the important process that promote network quality.
Mobile communications network develops to 3G, 4G from traditional 2G network at present, and the exchange of speech network of core net is changed into the IP switch mode from traditional circuit switched mode.The particularity that The application of new technique and mobile communication wireless insert; Make voice quality problem become very outstanding; Situation such as the single-pass of user's communication, no audio, call drop, metallic sound, noise directly influence user's impression, thereby have a strong impact on the competitiveness of common carrier.Because the user of mobile network inserts part and adopts wireless mode; Factors such as covering, landform, building, interference can influence voice quality; The interference that 3G network and frequency increase bring; The user increases the load that brings, and the load that mobile data services are brought all makes the voice quality of network faces real-time change; The IP switch mode is to adopt the mode of common source in addition, and how the loss that can bring quality is found and the voice quality problem of locating these appearance is the keys that improve voice quality.
Present known voice quality analysis has following several kinds of modes:
1, adopts the mode regularly dial to carry out the judgement of voice quality,, find the voice quality problem of network through manual work or the testing instrument test calls of conversing; This mode can only be analyzed the speech quality of calling, and guarantees the basic service ability of network, can't assess other magnanimity actual user speech quality.
2, RTP (Real time Transport Protocol) and RTCP (the Real time Transport ControlProtocol) bag through gathering IP network; Analyze packet loss, shake, the time delay of RTP; Estimate MOS value and the R coefficient of RTP, thus the voice quality of judges; What this mode was mainly estimated is the influence of IP network to voice quality, in the mobile network, to voice quality impacts maximum be the wireless access part, so this method can't satisfy the requirement of mobile network voice quality analysis.
3, RTP and the RTCP bag through gathering IP network judged the duration that does not send RTP on each direction, confirms the silent duration of user, judges that conversation is single-pass or no audio; The inaccuracy as a result that this method is judged because the RTP layer is not given out a contract for a project, does not just have a kind of embodiment mode of voice; In addition, there is the RTP bag also not necessarily represent user's voice messaging; And under a lot of conversation models, exist and have only the side user situation of speaking for a long time, for example a side listens an other side in a minute for a long time, or when ring, can produce erroneous judgement like this; This analysis simultaneously can not be judged the degree of noise, has no idea to navigate to concrete sub-district and concrete wireless network environment to the situation of the voice quality difference that monitors.
4, to the duration of call of certain object or take duration and add up judgement, be exactly to judge on the principle through short conversation takes place this object the ratio or the frequency, judge whether this object is to have voice quality problem; This mode can only be the supposition through model, generally navigates to sub-district or circuit; But in fact in a lot of zones or object, there is the normal short conversation of vast scale really, so the situation that has erroneous judgement and fail to judge; This in addition analytical method can only be analyzed the object of regional extent class, can not analyze the user, and the analysis of very big limitation, especially high-end user is arranged; This scheme can't be analyzed situation such as noise are big.
5, repeat at short notice to dial 2 times or repeatedly call out through two users; Being judged as voice quality goes wrong; But user's possibility of repeated call at short notice is also bigger; And having the calling of voice quality problem also not necessarily will initiate repeated call, there is erroneous judgement in this mode and fails to judge.
6, analyze through the message of gathering the user radio data, obtain user's information such as wireless quality, voice quality, power at interfaces such as Abis interface, Iub interface, analyze the termination of a call that occurs owing to the index deterioration, be judged as voice quality problem; Because to the influence of voice quality, wireless portion is a part just, parts such as transmission circuit, core net and IP network also all can exert an influence to voice quality; And wireless index information can only the indirect reaction voice quality, can't accurately judge the voice quality situation.
7, find voice quality problem through the customer complaint mode, this mode is very passive, has only few certain customers to feed back quality problems, and positional information can only be provided, and other data are difficult to obtain.
In sum; At present technical scheme exist aspect the accuracy that detects voice quality, the comprehensive and deep-going obviously not enough; Each mobile subscriber's actual speech quality situation can not be accurately analyzed, the needs that promote voice quality, improve user's perception can't be satisfied.
Summary of the invention
