Description

A kind of VoLTE voice quality monitors method and system
Technical field
The present embodiments relate to field of communication technology, more particularly, to a kind of VoLTE voice quality monitors method and System.
Background technology
4G networks can provide the data service of high-speed, and by numerous 4G customer acceptances, while 4G networks can also provide The voice and video telephone of high quality, i.e. VoLTE (Voice over LTE).VoLTE technologies bring 4G user and most directly experience just It is to turn on shorter stand-by period and higher quality, more natural voice and video communication effect.VoLTE and 2G, 3G voice communication It is essentially different, VoLTE is end-to-end speech scheme of the framework on 4G networks under the conditions of full IP.Because employing high-resolution Rate encoding and decoding technique, VoLTE compare 2G, 3G voice communication, and voice quality can improve 40% or so.VoLTE is brought more for user Low access delay (stand-by period after dialing), than 3G drops 50%, probably at 2 seconds or so, and the 2G epoch were at 6-7 seconds.In addition, Call drop under 2G, 3G happens occasionally, but the drop rate of VoLTE is close to zero.
But there is also problems by VoLTE：Connect once in a while obstructed, speech quality occur discontinuously, gulp down that word etc. is as one wishes not to the utmost to be showed As greatly affected user's conversion ratio of VoLTE, therefore can accurately be delimited there is an urgent need for one kind and quickly judge user speech The monitoring method of perception, so as to further promote VoLTE voice qualities.
At present, International Telecommunication Union (International Telecommunication Union, ITU) Speech Assessment Algorithm standard rules have：PAMS (perception analysis photometry system), PSQM (perceptual speech quality is estimated), MNB (normalization block estimate), PESQ (assessment of consciousness speech quality), E-Model (ITU is G.107).Wherein, PAMS, PSQM, MNB, PESQ use MOS boxes Reference signal is transmitted and received on telecommunication network, the signal quality sent and received is assessed by Speech Assessment algorithm.
Specifically, MOS boxes test accuracy is higher, but since MOS tests are more demanding (to mobile phone to hardware device Data line and USB jack requirement are harsh) and power consumption it is larger (needing continuously to give the power supply of MOS boxes in test process), also need manually Live drive test is carried out, not only increases manpower and material resources cost, and is not suitable for flatbed and counts the evaluation of the whole network voice quality.
E-Model is network-based quality, is suitble to the assessment of the whole network voice quality.The calculation formula of E-Model is：
R=Ro-Is-Id-Ie-eff=A
Wherein Ro represents network transmission signal-to-noise ratio, and Is represents equipment deterioration combined probability, Id represent due to when extend to equipment Superposition deterioration caused by failure, the deterioration factor that Ie representatives are brought by low bit rate encoder.Coefficient A is used for user environment shape The compensation of state (such as indoor/outdoor, low speed are mobile, high-speed mobile).
Due in above-mentioned E-modle calculation formula parameters define it is too abstract, can will be upper it is difficult to instruct actual production The Ro stated in E-Model calculation formula is adjusted according to code/decode type, then E-Model calculation formula are revised as：
R=R'- (R1*2.5)
Wherein, R ' sets following Rule of judgment to form by Effective Latency=(Td+Rj*2+10)
if Effective Latency<160 then
R '=R0- (Effective Latency/40)
else
R '=R0- (Effective Latency-120)/10
The correspondence of voice coding and R0 are as shown in table 1：
Table 1
Codec Name R0
AMR NB(12.2) 91
AMR WB(23.85) 107
R values and the correspondence of MOS values are as shown in table 2：
Table 2
Although E-modle models are suitble to flatbed to count the evaluation of the whole network voice quality, it can reflect time delay, shake and lose The problem of data networks such as packet are peculiar, but using E-modle models this assumes that voice quality impairments factor always physics It is additional, the credit rating of ability one network of comprehensive objective estimation so that its algorithm is extremely complex, and can only calculate MOS values can not carry out the demarcation positioning of problem network element.

In view of the mobile status of user, serving cell may change, therefore, by RTP voice packets in time Multiple durations are divided into be monitored.In real-time monitoring, i.e., with default RTP of the monitoring cycle between first end and second end The periodical monitoring of voice flow progress, the period sending cycle that wherein predetermined period can be sent for RTCP, generally 5 seconds.It can be with Periodical monitoring pattern is interpreted as thin slice monitoring pattern by image, a length of one default monitoring week when each thin slice is corresponding Phase.The monitoring in one default monitoring cycle of RTP voice flows will be also known as in the embodiment of the present invention one thin to RTP voice flows The monitoring of piece.
As shown in figure 3, for the convenience of description, primary call, the concept of forward and backward is defined：Forward direction voice flow (caller Terminal is to called terminal) and backward voice flow (called terminal to calling terminal)；Similarly, RTCP is also divided to two kinds, forward direction RTCP packets (calling terminal to called terminal) and backward RTCP packets (called terminal issues calling terminal).S1-U and Gm two is acquired by monitoring The RTP/RTCP data packets of a interface, therefore forward and backward can access the CDR of 4 RTP in each default monitoring cycle (before RTP_ to/it is rear after _ MO_S1U, RTP_ before before/backward _ MO_Gm, RTP_ before/backward _ MT_S1U, RTP_ to/it is backward _ MT_Gm)。
In step s3, by taking packet loss as an example, illustrate the packet loss according to each monitoring point in each default monitoring cycle, really The source stream of the problem of voice quality being caused to perceive difference in fixed each default monitoring cycle network element.In embodiments of the present invention, it determines Problem network element is also referred to as demarcation problem network element.
4 monitoring points, which are analyzed to calculate to monitor respectively by RTP, obtains the KPI (packet loss) of the monitoring point, respectively：KPI_ A、KPI_B、KPI_C、KPI_D.In addition four indexs as shown in table 3 are defined respectively：
Table 3
KPI_ (B-A)=KPI_B-KPI_A
KPI_ (C-B)=KPI_C-KPI_B
KPI_ (D-C)=KPI_D-KPI_C
KPI_ (P-D)=KPI_RTCP-KPI_D
By taking the KPI_ (B-A) of packet loss as an example, meaning is the packet drop between A monitoring points and B monitoring points, other refer to Mark and so on.
Compare KPI_A, KPI_ (B-A), KPI_ (C-B), KPI_ (D-C), KPI_ (P-D) obtain this matter difference business most Big problem points, problem points and the correspondence of problem network element are as shown in table 4：
Table 4

Specifically, obtain the speech perception of user, not be to single sheet analysis just can obtain, need before and after it is multiple Thin slice is completed jointly.Therefore it needs to define a few class parameters (continuity Characteristics extraction function, threshold trait extraction function and perception knowledge Other function).
Continuity Characteristics recognition function：In forward or a backward RTCP, the number of some threshold value is continued to exceed, such as more than 10 Second (i.e. at least continuous 3 thin slice time) RTP packet loss about 30%.
Threshold trait extracts function：In forward or a backward RTCP, more than the number of some threshold value, for example packet loss is 10% With 30% thin slice number.
Perceive recognition function：Using two kinds of two sides feature recognition function as a result, to weight the speech perception for acquiring user.
Because single-pass caused by terminal reason or encoding and decoding reason gulps down word, discontinuously, can not be obtained in RTCP report accordingly Feature.Therefore only consider the situation of the voice quality difference caused by packet loss, shake.Judgment rule is as shown in table 5：
Table 5
