FIG. 1 shows a schematic diagram of a network quality management system 100 according to an embodiment of the present invention. The management system 100 is suitable for managing the network quality of each network device in a field, wherein the field corresponds to a network (for example, a local area network). Network devices in the field can access the network. The management system 100 may include a processor 110 , a storage medium 120 and a transceiver 130 .

The processor 110 is, for example, a central processing unit (central processing unit, CPU), or other programmable general purpose or special purpose micro control unit (micro control unit, MCU), microprocessor (microprocessor), digital signal processing Digital signal processor (DSP), programmable controller, application specific integrated circuit (ASIC), graphics processing unit (graphics processing unit, GPU), image signal processor (image signal processor, ISP) ), image processing unit (image processing unit, IPU), arithmetic logic unit (arithmetic logic unit, ALU), complex programmable logic device (complex programmable logic device, CPLD), field programmable logic gate array (field programmable gate array , FPGA) or other similar components or combinations of the above components. The processor 110 can be coupled to the storage medium 120 and the transceiver 130 , and access and execute multiple modules and various application programs stored in the storage medium 120 .

FIG. 2 shows a flowchart of a network quality management method according to an embodiment of the present invention, wherein the management method can be implemented by the management system 100 shown in FIG. 1 .

In step S201 , the environment detection module 121 can detect the movement of people in the field through the transceiver 130 to generate a detection result. Specifically, the environment detection module 121 can periodically send a radio frequency signal (for example, a millimeter wave signal) to the field through the transceiver 130 and receive a reflected signal corresponding to the radio frequency signal. The environment detection module 121 can judge whether there is a person in the field and whether the person moves according to the reflected signal, so as to generate a detection result. In one embodiment, the environment detection module 121 can also obtain the location information of the people in the field according to the reflected signal.

In step S202 , the environment detection module 121 can determine whether the movement of people in the field is detected according to the detection result. If the movement is detected, go to step S203. If the movement is not detected, go to step S204.

In step S203, the quality measurement module 122 may not perform network quality measurement in response to detecting the movement of the person. That is to say, when there are moving people in the field monitored by the management system 100 , the management system 100 may not perform network quality measurement, so as to avoid occupying network resources and affecting the people's experience of using the network.

In step S204 , the environment detection module 121 can detect the network traffic of the field through the transceiver 130 . The quality measurement module 122 can determine that the network is being used according to the traffic of the network. If the network is in use, go to step S203. If the network is not in use, go to step S204. Specifically, the traffic detected by the environment detection module 121 may include traffic information of all network devices (or all network devices served by the network) in the field. The quality measurement module 122 can determine the use status of any network device in the field according to the traffic, where the use status can indicate whether the network device is being used by personnel. If a person uses any network device in the field, the quality measurement module 122 can determine that the network is being used. If the person does not use any network device in the field, the quality measurement module 122 can determine that the network is not in use.

…(3) On the other hand, the environment detection module 121 can detect the network to obtain the first current traffic corresponding to all the network devices and the second current traffic corresponding to the at least one fixed network device. The quality measurement module 122 can determine to perform the network quality measurement in response to the condition of equation (3), wherein x is the first current traffic, and y is the second current traffic. In this embodiment, all network devices in the field are classified into fixed network devices and portable network devices. It can be known from the equation (3) that the quality measurement module 122 can decide to perform the network quality measurement when the traffic of the portable network device is relatively small and the traffic of the fixed network device is relatively large. In this way, the experience of the user when using the portable network device to access the network can be improved.

In one embodiment, the quality measurement module 122 can determine whether the network device is a fixed network device or a portable network device according to the count value of the network device. FIG. 3 shows a flow chart of a method for adjusting a count value of a network device according to an embodiment of the present invention, wherein the adjustment method can be implemented by the management system 100 shown in FIG. 1 .

In step S301 , the environment detection module 121 can detect network devices accessing the network through the transceiver 130 to obtain a connection list corresponding to the network. The connection list may include media access control (MAC) addresses of one or more network devices. When the MAC address of a network device is in the connection list, it means that the network device is accessing the network.

In step S302, the environment detection module 121 can determine whether the movement of people in the field is detected. For example, the environment detection module 121 can determine whether the movement of people in the field is detected according to the method described in step S201 and step S202 of FIG. 2 . If the movement is detected, go to step S303. If the movement is not detected, go to step S304.

In step S303, the quality measurement module 122 can increase the count value of each network device in the connection list. In step S304, the quality measurement module 122 may decrease the count value of each network device in the connection list. The analysis module 123 can determine whether the network device is a fixed network device or a portable network device according to the count value of the network device. In one embodiment, the analysis module 123 may determine that the network device is a fixed network device in response to the count value of the network device being less than a threshold. On the other hand, the analysis module 123 may determine that the network device is a portable network device in response to the count value of the network device being greater than or equal to a threshold. In other words, a network device that accesses the network when a person moves in the field is more likely to be judged as a portable network device. Network devices that access the network when people are not moving around the premises are more likely to be classified as fixed network devices.

Returning to FIG. 2, in step S205, the quality measurement module 122 performs the network quality measurement to obtain the traffic parameters of each network device in the field through the transceiver 130, and the traffic parameters may include received signal strength indicators (received signal strength indicator, RSSI), bandwidth, packet loss rate, error, delay, or quality of service (quality of service, QoS) and other parameters, but the present invention is not limited thereto.

In step S206 , the analysis module 123 can generate a quality measurement report of the network according to the traffic parameters, and output the quality measurement report through the transceiver 130 . Quality measurement reports can include data such as network quality of the network or location information of personnel. For example, the analysis module 123 can send the quality measurement report to the administrator of the network service provider. The administrator can judge how to improve the user experience of the network according to the quality measurement report.

In one embodiment, the analysis module 123 can calculate the network quality according to the traffic parameters and weights of each network device in the field, so as to generate a quality measurement report, wherein the weight is related to the type of network device (such as : fixed network equipment or portable network equipment). Specifically, after the quality measurement module 122 obtains the count value of the network device according to the method shown in FIG. 3 , the analysis module 123 can determine the weight of the network device according to the count value. The count value of the network device may be directly proportional to the weight of the network device. The greater the weight of the network device, the greater the influence of the network device on the calculation result of the network quality. In other words, compared with fixed network devices, portable network devices have a greater impact on the calculation results of network quality. In this way, if the network service provider determines the network configuration parameters based on the network quality in the quality measurement report to improve the user's network experience, compared with fixed network devices, portable network devices will be significantly improved.

FIG. 4 is a flow chart of a network quality management method according to another embodiment of the present invention. The management method is suitable for managing the network quality of each network device in a field, wherein the field corresponds to a network (for example: local area network). The management method can be implemented by the management system 100 shown in FIG. 1 . In step S401, the movement of people in the field is detected, and the traffic of the network of the field is detected in response to no movement being detected. In step S402, network quality measurement is performed according to the traffic judgment to obtain traffic parameters of the network equipment. In step S403, a network quality measurement report is generated according to the traffic parameters, and the quality measurement report is output.

In summary, the present invention has the following characteristics and effects: through the framework of the system of the present invention, system developers can quickly develop a system that accurately determines the user's usage status, and then captures user experience information, which is useful for improving User experience provides a more accurate judgment module, reducing the cost of service providers to improve user experience; the system of the present invention can avoid simultaneous use of user use and quality measurement, maintain the quality of user experience and quality measurement, and further Reduce the frequency of user complaints and improve the judgment of service providers to improve network quality; using the system of the present invention, service providers can reduce the need to visit customers' homes to judge network problems, and the system can judge user service abnormalities and occurrence locations; using this system The invention system can determine the type of equipment, which can be divided into fixed equipment and portable equipment.
