The invention is further described in the following description and embodiments with reference to the drawings.
As shown in fig. 1, a method for testing an index of user experience satisfaction of a WIFI product simultaneously tests MOS, delay, jitter, and packet loss rate on the basis of testing throughput in scenarios of attenuation, interference resistance, and the like, so as to measure user experience satisfaction in each scenario.
The configuration and connections are described as follows:
1. under the test environments of attenuation, directivity, same frequency interference, adjacent frequency interference and the like, on the basis of testing the throughput index, the indexes of MoS, time delay, jitter, packet loss rate and the like are tested.
2. The wired PC is a desktop computer or an industrial personal computer with gigabit network cards, and Ixcharoot and endpoint are installed; the wired network card is connected to a LAN port of a DUT (device under test).
The ixchariot is a well-known detection tool applied to network performance testing, has a strong control end and a terminal simulation control technology, and can be respectively installed on a common pc or a server to comprehensively evaluate the throughput, time delay, jitter, packet loss, packet error and the like of the network, quantitative data can be simply and reasonably analyzed by a detailed test report, and a user can reasonably master the performance condition of equipment.
EndPoint is mainly used for exposing some information running inside the SpringMvc, and the related information is usually obtained through the request address of the SpringMvc. Such as/health, to obtain health check information.
3. The wireless terminal is a desktop or notebook computer provided with a 2T2R 11AX wireless network card AX200, and the WIN10 operating system is provided with Ixchoriot and endpoint; or an 11AX handset with an Ixchariot EP APP installed.
4. The wireless terminal connects 2.4G or 5G wireless of the DUT, tests the throughput, moS, delay, jitter and packet loss rate of 2.4G or 5G transmission/reception.
MOS (Mean Opinion Score) is a communication term, and is often an important indicator for measuring the voice quality of a communication system.
The specific working process of the invention is as follows:
description of the working principle:
1. the WMM (Wi-Fi multimedia) function of the wireless AP (wireless Access point) has 4 queues, namely AC (Access Category) _ VO (Voice), AC _ VI (Video), AC _ BE (Best Effort) and AC _ BK (Background), which respectively correspond to a Voice stream, a Video stream, a Best Effort stream and a Background stream, and the priority is from high to low.
2. And the wired PC runs Chariot, a plurality of TCP thread Pair from the wired PC to the wireless terminal and a UDP VoIP Pair from the wired PC to the wireless terminal are newly built, and the VoIP configures the VoIPQoS priority. For a VoIP flow with priority, the AC _ VO queue should BE taken normally, the thread takes the AC _ BE queue, and the AC _ VO is preferentially forwarded before the AC _ BE.
Throughput is the Throughput, while VoIP is voice over IP transmission.
3. Clicking a RUN (operation) button of Chariot, and recording data such as the transmission throughput, moS, delay, packet loss rate, jitter and the like of the AP after running.
4. Exchanging all Pair transmitting and receiving directions, testing AP receiving throughput, moS, time delay, packet loss rate and jitter
5. Normal AC _ VO would prioritize forwarding processing over AC _ BE. Regardless of the scenario, the MoS of VoIP Pair should not be lower than 3.6, and neither throughput nor MoS is lower than the bid; otherwise, the user experience satisfaction degree is influenced or the user experience is worse than that of the competitive products under the scene.
6.MOS < -3.6, which indicates that the user experience indexes do not reach the standards; the throughput and MoS are lower than those of a competitive product, which shows that the user experience is worse than that of the competitive product; throughput is better than the bid, and MoS is lower than the bid, indicating that the wireless AP does not implement the WMM queue priority function.
And (5) judging a result:
MoS > =3.6, and throughput and MoS are superior to or equivalent to a bid.
The MOS score ranges from 1 to 5, where a score of 1 indicates that the user experience is very poor and a score of 5 indicates that the user experience is very satisfactory. The details are shown in table 1:
TABLE 1
| Lower limit of | Upper limit of | Degree of satisfaction of user |
| 4.34 | 5.00 | Is very satisfactory |
| 4.03 | 4.34 | Satisfaction |
| 3.60 | 4.03 | Partial user satisfaction |
| 3.10 | 3.60 | A lot of user dissatisfaction |
| 2.58 | 3.10 | Almost all users are dissatisfied |
| 1.00 | 2.58 | Is not receivable |

1. the invention simultaneously tests throughput, moS, delay, jitter and packet loss rate, and the MoS is directly hooked with the user experience satisfaction;
2. the invention tests Throughput and VoIP at the same time, can test VoIP and flow away AC _ VO queue, throughput flows away the validity of AC _ BE queue, moS value can reflect VI queue priority BE queue validity;
