Brief description of the drawings
Fig. 1 is the video measurement flow chart of mobile Internet of the present invention.
Embodiment
Below in conjunction with accompanying drawing, preferred forms of the present invention is described in detail.
As shown in Figure 1, the video measurement method of mobile Internet of the present invention comprises the following steps:
1) determine the test specification of measuring network belonging network formats and belonging network standard, the agreement of described network formats support comprises realtime transmission protocol RTP, real-time streaming protocol RTSP, resource reservation protocol RSVP and Session Description Protocol SDP etc., and described network is made as TD-SCDMA, WCDMA, CDMA2000;
2) the selected region that will measure;
3) the selected time period that will measure;
4) measure the packet loss of video and record its fractional value LT according to client perception index system;
5) number of times of the time delay of measurement video and each duration, record its score value SY;
6) number of dropped calls of measurement video and each duration, record its score value DX;
7) the 3G to 2G accounting of measurement video, records its score value ZB;
8) the 2G online duration accounting of measurement video, records its score value 2G
zB;
9) according to formula
measured score value is added, obtaining concrete fractional value assesses the service quality of mobile Internet operator, wherein, described video format comprises 3GP, ASF, AVI, FLV, rmvb and MP4 etc., before test video, coding tools passes through coding various video formats automatically, the unified H.264 video compression standard that changes into.
Concrete data test of the present invention is as follows:
1, test packet loss
Packet loss (Loss Tolerance or packet loss rate) refers to institute's lost data packets quantity in test
account for sent data packet number
ratio, conventionally at throughput scope build-in test.For video, packet loss is one of key factor affecting user's experience.Fig. 1 is current main flow video-on-demand applications PPLIVE, relation when 400K encoding rate that excellent storehouse etc. are used between packet loss and PSNR.Through linear, square, find to exist between packet loss and PSNR obvious cube relation after the Model Matching such as mixing, logarithm, power, cube.Be shape as:
so,, necessary to packet loss rate measurement.Packet loss is used
represent, wherein
the concrete data of regulation are as shown in table 1,
Table 1
2, test time delay
The time delay here refers to the time delay of video download package, specifically comprises: client log in duration, client mode play waiting time, column switch duration, enter details duration, WAP plays waiting time.General people can stand the time delay that is less than 250ms, if time delay is oversize, can make client feel under the weather, and affect user perceptibility, therefore, are necessary time delay to test.Test data mainly by the mode of signaling tracing and bottom packet capturing record UE response time, PDP activationary time, service request processing time (log in, column switches, enter details), content displaying time, play link settling time, play buffering time etc.By the analysis to operation flow, known terminal is in the process of establishing of signaling plane and transmission face, the message that terminal is asked, after related network elements is processed end to end, finally response message can be looped back to terminal, therefore, work out the time delay index of end side links in operation flow, can more clearly locate, in the time that the overall time delay index of mobile video main business workflow is not up to standard, be due in flow process which link time delay is undesirable causes, need thereby can locate faster the network element device optimizing and improve.The inventive method puts aside how to optimize here, only points out the time delay duration of test
average frequency with time delay generation
, wherein regulation:
unit: second;
unit: inferior/hour.Concrete data representation is as table 2.
Table 2
3, test the situation that goes offline
Go offline, improper data when network connects connect and stop, or are connected disconnection while watching video with server.Go offline and can consider by two indexs, one is the number of times that user goes offline while surfing the Net, and another is the duration at every turn going offline.Due to watching in video, going offline can have a strong impact on user and experience impression, so be very important detection index in the video measurement of mobile Internet.Wherein, regulation:
unit: second;
unit: inferior/hour, concrete data are as shown in table 3.
Table 3
4, test 3G to 2G accounting
3G to 2G accounting, in test process, the number of times that is switched to 2G network by 3G network is 3G to 2G accounting with the ratio of test total degree.Because networking speed, the drop rate etc. of 3G network are obviously better than 2G network, so the larger explanation client perception of this accounting is poorer, the accounting value is here used
represent, corresponding fractional value is used
represent.Its concrete data are as shown in table 4.
Table 4
5, test 2G online duration
Causing the reason of 2G online is 3G network poor signal, so test 2G online duration accounting can be from the situation of an aspect reflection 3G network, the 2G surf time is longer, illustrates that network state is more bad.Total be exactly the 2G online duration accounting 2G surf time and the ratio of surf time.Here 2G online duration accounting is with representing, the overall score of this accounting is with representing, its concrete data are as shown in table 5.
Table 5
6, comprehensive assessment
According to
above-mentioned measured score value is added, mobile internet service business's service quality is carried out to grade classification and become five grade: A, B, C, D, E, the corresponding fractional value of each grade and review as shown in table 6.
Table 6
| Measure score value | (400,500] | (350,400] | (300,350] | (250,300] | [0,250] |
| Grade | A | B | C | D | E |
| Evaluate | Outstanding | Well | Generally | Bad | Poor |
Only as described above, it is only the present invention's preferred embodiment, certainly can not limit with this scope of the invention process, the content of generally recording according to the claims in the present invention and description of the invention has been done simple equivalence and has been changed and modify, and is all still covered by the claims of the invention.In addition, summary part and title are only the use for auxiliary patent document search, are not used for limiting the present invention's interest field.
