Taking a home internet as an example, a large number of home intelligent devices, home sensors and the like can be built into a home network, and a user can realize home entertainment, communication social contact, auxiliary management life and the like through the home network, so that more portable and intelligent life can be provided according to the user requirements. At present, a home network mainly adopts a wireless local area network to realize interconnection, and an intelligent gateway can be used as a device for providing wireless signals and can be used for connecting other household intelligent devices and household sensors and other access devices. In an actual application scenario, due to the influence of factors such as a house type, a wall, signal interference or a position relationship of an access device, the problems of poor coverage or weak signal of the access device may exist in a home network, and thus user experience is reduced.

Disclosure of Invention

The embodiment of the application provides an access device layout method, an access device layout device, a network device and a readable storage medium, which are used for providing a technical scheme for more efficiently and accurately identifying poor coverage or weak signals of the access device in a home network.

In a first aspect, an embodiment of the present application provides an access device layout method, including: the method comprises the steps that a network device obtains N Received Signal Strength Indications (RSSI) of N access devices contained in a target local area network, wherein the N access devices correspond to the N RSSIs one by one, and N is a positive integer; the RSSI of the access equipment is larger, and the signal quality of the access equipment is higher; the network equipment analyzes the N RSSIs, and divides the target local area network into a plurality of area ranges, wherein each area range corresponds to the RSSI in different value ranges; the network equipment evaluates the signal quality of the target local area network according to the plurality of area ranges to obtain an evaluation result; and the network equipment generates a target layout mode for at least one access equipment according to the evaluation result.

In the method, the network equipment collects and analyzes the RSSI information of the access equipment contained in the target local area network, divides the target local area network into a plurality of logical area ranges corresponding to the RSSIs with different value ranges on the basis of the RSSI, and can realize the evaluation of the signal quality of the target local area network on the basis of the divided area ranges and the area range where each access equipment is located, thereby accurately analyzing the reason of poor signal quality of the access equipment and the like. For example, the access device itself has quality problems, for example, because the wireless signal strength of the area range where the access device is located is generally poor, or the wireless signal coverage capability in the target local area network is poor. And, through the signal quality assessment of the network equipment to the target LAN, can also produce the corresponding target layout mode according to the result of assessment. Therefore, technicians can be prevented from going home many times, and a preliminary judgment result can be obtained based on analysis of the network equipment, so that the efficiency, the accuracy and the like of identifying the problems of poor coverage or weak signals of the access equipment in the local area network can be improved.

In one possible design, the network device analyzes the N RSSIs, divides the target local area network into a plurality of area ranges, and may be implemented to cluster the N RSSIs to obtain a plurality of cluster categories; and dividing the target local area network into the plurality of area ranges according to the plurality of clustering categories, wherein the clustering categories correspond to the area ranges one by one.

In the design, a plurality of area ranges are obtained through a clustering mode, and the RSSI of the target local area network based on the access equipment can be more accurately classified, so that more accurate evaluation results and a target layout mode can be obtained.

In one possible design, the network device obtains N RSSIs of N access devices included in a target local area network, and may be implemented to periodically receive M sub-RSSIs reported by the N access devices, respectively, and an acquisition time corresponding to each sub-RSSI, where M is a positive integer. For the ith access device, performing: the network equipment divides the M sub-RSSIs into a plurality of time slot groups based on the acquisition time corresponding to the M sub-RSSIs respectively reported by the ith access equipment, and determines the dispersion of the plurality of sub-RSSIs in each time slot group; the network equipment selects a target time period group according to the dispersion of a plurality of sub-RSSIs contained in the time period groups, and obtains the RSSI of the ith access equipment according to the plurality of sub-RSSIs contained in the target time period group; wherein, i is respectively taken as any one positive integer from 1 to N.

In the design, in a time period group with large fluctuation of the signal intensity of the access equipment, the evaluation result of the network equipment also has obvious change; and in a time slot group with small fluctuation of the signal strength of the access equipment, the evaluation result of the network equipment is stable. Therefore, the network device realizes the quality evaluation of the target local area network based on the data in the time period group with smaller dispersion in the acquired sub RSSI information of the access device, and can improve the accuracy of the evaluation result.

In one possible design, the dispersion may include, but is not limited to, one or a combination of the following information: coefficient of variation CV of fluctuation, difference between maximum RSSI and minimum RSSI, variance, etc. The network device selects a target time period group according to the dispersion of the plurality of sub-RSSIs included in the plurality of time period groups, and if the dispersion is the fluctuation CV, the network device takes a time period group in which the fluctuation variation coefficient CV of the plurality of sub-RSSIs included in the plurality of time period groups is smaller than a first threshold value as the target time period group; or if the dispersion is the difference between the maximum RSSI and the minimum RSSI, the network device uses a time period group, in which the difference between the maximum RSSI and the minimum RSSI in a plurality of sub-RSSIs included in the time period groups is smaller than a second threshold, as the target time period group; or, if the dispersion is the variance, the network device sets a time slot group, in which the variance of a plurality of sub-RSSIs included in the time slot groups is smaller than a third threshold value, as the target time slot group.

In the design, the accuracy of the evaluation result can be improved by combining several possible dispersion determination modes.

In a possible design, the network device obtains the RSSI of the ith access device according to a plurality of sub-RSSIs included in the target time slot group, and may be implemented to normalize the plurality of sub-RSSIs included in the target time slot group to obtain the RSSI of the ith access device.

In the design, the network equipment can improve the RSSI precision of the access equipment through the normalization processing of the RSSI sample data of the access equipment, and further can ensure the accuracy of the evaluation result of the target local area network.

In one possible design, the network device may normalize the plurality of sub-RSSIs included in the target time segment group by performing an averaging operation or a weighted averaging operation on the plurality of sub-RSSIs included in the target time segment group.

In one possible design, the network device may evaluate the signal quality of the target local area network according to the plurality of area ranges, and may determine that the first area range is an active area if it is identified that the number of access devices included in the first area range is greater than or equal to a first number threshold, or if it is identified that the network duration of the access devices in the first area range is greater than or equal to a first duration threshold. The method can also be implemented to determine the second area range as an inactive area if the number of the access devices contained in the second area range is smaller than a second number threshold or the network duration of the access devices in the second area range is smaller than a second duration threshold. Wherein the first area range or the second area range is any one of the plurality of area ranges.

In this design, it can be understood that the active region may be a region where the user needs to use the target lan more, and therefore, the signal quality of the active region has a greater influence on most users in the target lan. Therefore, by evaluating the wireless signal strength of the inactive area and the active area, the network distribution condition of the target local area network can be analyzed in time according to the use requirements of users, and therefore the problems and the like in the target local area network can be checked in time.

In a possible design, the network device generates a target layout manner for at least one access device according to the evaluation result, which may be implemented to generate a first target layout manner if the RSSI included in the active region is lower than a first RSSI threshold; wherein, the first target layout mode may include, but is not limited to, one or a combination of the following modes: for an Access Point (AP) contained in the target local area network, adjusting the distance between the AP and at least one access device contained in the active area; adding one or more APs to the active region; and the like.

In the design, through the evaluation of the signal quality of the active region, when the active region is abnormal, a proper target layout mode can be generated in time, so that the efficiency of eliminating the abnormality in the target local area network for the user is improved.

In one possible design, the network device may evaluate the signal quality of the target local area network according to the plurality of area ranges, and may be implemented to receive an evaluation request for a first access device, where the first access device is any access device in the N access devices; the network device determines a third area range in which the first access device is located according to the evaluation request, wherein the third area range is any one of the area ranges; the network equipment determines that at least one RSSI (received signal strength indicator) in the third area range is smaller than a second RSSI threshold value, and determines that the evaluation result is that the signal quality of the first access equipment is first quality; and the network equipment determines that the RSSI contained in the third area range is greater than or equal to the second RSSI threshold value, and determines that the evaluation result is that the signal quality of the first access equipment is the second quality.

In the design, based on a plurality of area ranges obtained by the network equipment, the signal quality of each access equipment can be evaluated, so that the accuracy of network anomaly investigation of the access equipment can be improved.

In a possible design, the network device generates a target layout manner for the first access device according to the evaluation result, and may be implemented to generate a second target layout manner when the evaluation result is that the signal quality of the first access device is a first quality; wherein, the second target layout mode may include, but is not limited to, one or a combination of the following modes: adjusting the distance between the first access equipment and the AP connected with the first access equipment; adjusting the distance between the first access equipment and a gateway connected with the first access equipment; improving the transmission bandwidth of the AP or the gateway connected with the first access equipment; and the like.

In the design, through the evaluation of the signal quality of the access equipment, when the signal quality of the access equipment is determined to be abnormal, a proper target layout mode can be generated in time, so that the efficiency of eliminating the abnormality of the access equipment for a user is improved.

In one possible design, the method further includes: the network device sends prompt information to at least one target access device, wherein the prompt information may contain one or a combination of the following information: the evaluation result and the target layout mode; the target access device is any one of the N access devices, or the target access device is a device independent of the N access devices; and the like.

Some terms of the embodiments of the present application are explained below to facilitate understanding by those skilled in the art.

1) Network devices, including, for example, access Network (AN) devices, such as base stations (e.g., access points), may refer to devices in AN access network that communicate with wireless terminal devices over one or more cells over AN air interface. The base station may be configured to interconvert received air frames and IP packets as a router between the terminal device and the rest of the access network, which may include an IP network. The network device may also coordinate attribute management for the air interface. For example, the network device may include an evolved Node B (NodeB or eNB or e-NodeB) in a Long Term Evolution (LTE) system or an advanced long term evolution (LTE-a), or may also include a next generation Node B (gNB) in a fifth generation mobile communication technology (5 g) NR system (also referred to as NR system) or may also include a Centralized Unit (CU) and a Distributed Unit (DU) in a Cloud access network (Cloud RAN) system, which is not limited in the embodiments of the present application.

The network device may also include a Core Network (CN) device including, for example, an access and mobility management function (AMF) and the like.

Still alternatively, in some possible application scenarios, the network device may also be a DSL device, a PON device, a router, and/or a switch.

By way of example and not limitation, in the embodiment of the present application, the network device may also be an application function entity (AF) network element, a gateway (such as an enterprise gateway or a home gateway), or a network management system (such as the home network management system introduced in fig. 1, or the enterprise network management system introduced in fig. 2), and the like. For example, the gateway may be a router, and the network management system may be a management server for managing terminal devices in a network, or the like.

2) An access device, a user equipment (such as a terminal device) or a network access device for accessing network resources, and the like.

Terminal equipment, also known as intelligent terminals or terminals, includes equipment that provides voice and/or data connectivity to a user, and may include, for example, handheld devices having wireless connection capabilities or processing devices connected to wireless modems. The terminal device may communicate with a core network via a Radio Access Network (RAN), exchanging voice and/or data with the RAN. The terminal device may include a User Equipment (UE), a wireless terminal device, a mobile terminal device, a device-to-device communication (D2D) terminal device, a machine-to-machine/machine-type communication (M2M/MTC) terminal device, an internet of things (IoT) terminal device, a subscriber unit (subscriber unit), a subscriber station (subscriber state), a mobile station (mobile state), a remote station (remote state), an AP, a remote terminal (remote), an access terminal (access terminal), a user terminal (user terminal), a user agent (user agent), or a user equipment (user device), etc. For example, mobile telephones (otherwise known as "cellular" telephones), computers with mobile terminal equipment, portable, pocket, hand-held, computer-embedded mobile devices, and the like may be included. For example, personal Communication Service (PCS) phones, cordless phones, session Initiation Protocol (SIP) phones, wireless Local Loop (WLL) stations, personal Digital Assistants (PDAs), and the like. Also included are constrained devices such as devices that consume less power, or devices that have limited storage capabilities, or devices that have limited computing capabilities, etc. Examples of information sensing devices include bar codes, radio Frequency Identification (RFID), sensors, global Positioning Systems (GPS), laser scanners, and the like.

By way of example and not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable equipment can also be called wearable smart device or intelligent wearable equipment etc. is the general term of using wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. The wearable device may be worn directly on the body or may be a portable device integrated into the user's clothing or accessory. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets, smart helmets, smart jewelry and the like for monitoring physical signs.

Still alternatively, in some application scenarios, the access device may also include other types of devices, such as a modem, a router, an Optical Network Terminal (ONT), and the like.

In combination with the description in the background art, for the problem that coverage is poor or signals of access equipment are weak in a local area network, a technical person is mainly used for performing identification in a field survey mode, and the mode has the problems of low efficiency or high cost and the like. For example, technical solutions exist for technicians to implement signal detection on a local area network by using a two-in-one tool for field detection and design of the local area network and adopting the modes of field entrance assessment, field design, networking construction, completion acceptance and comparison report. It can be understood that the technical solution needs to rely on special hardware detection equipment and needs a technician to operate on site, so that the disadvantages of high cost and poor efficiency exist. Or, at present, there is a way for professional technical maintenance personnel to perform multipoint testing and then give a test result. The method also has the defects that field operation is needed, and when the signal difference problem occurs again later, the door-to-door field test is still needed, so the method has high cost and cannot be generally applied.

In view of this, an embodiment of the present application provides an access device layout method. In a target local area network to be evaluated, such as fig. 1 or fig. 2, the embodiment of the present application may analyze, by a network device, RSSI information of one or more access devices included in the target local area network, so as to implement signal quality evaluation on the target local area network.

In the present application, the plurality of the "means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. In addition, it should be understood that, although the terms first, second, etc. may be used to describe various data in the embodiments of the present application, the data should not be limited to these terms. These terms are used only to distinguish data from each other.

Fig. 3 is a flowchart illustrating an access device layout method according to an embodiment of the present application. The method provided by the application can be realized by the following steps:

s301, a network device obtains N RSSIs of N access devices contained in a target local area network, wherein the N access devices correspond to the N RSSIs one by one, and N is a positive integer. The access equipment has higher signal quality when the RSSI of the access equipment is higher.

In conjunction with the home network architecture shown in fig. 1, the network device may be a management server for a home network management system to manage access devices in a home network, the target lan may be a home network, and the access device may be an AP or an STA shown in fig. 1 (in this embodiment, the "access device" may also be referred to as a "terminal device", and the like, and may be used alternatively in this embodiment). For example, the home network management system may request the home gateway to acquire device information of one or more terminal devices connected to the home network. As introduced in the foregoing, the device information of the terminal device may include DHCP client information and Wi-Fi information. The Wi-Fi information can comprise RSSI information used for characterizing the signal strength of the access equipment. For another example, the network device may also directly obtain RSSI information of N access devices included in the target lan. Furthermore, in addition to RSSI information, in some scenarios embodiments of the present application obtain Reference Signal Receiving Power (RSRP) information of the access device in place of the RSSI information to represent the access device signal strength; or the RSSI and the RSRP information jointly represent the signal strength of the access equipment, and the like; or, the RSSI information may be replaced with other information to indicate the signal strength of the access device, which is not limited in this application.

In the above example, the home network management system may send a GET _ SUB _ DEVICE _ LIST command to the gateway agent through the remote channel. The GET _ SUB _ DEVICE _ LIST command is used to instruct that DEVICE information/RSSI information of a terminal DEVICE connected to a home gateway is transmitted to the home network management system. The remote channel may perform message transmission based on a Message Queue Telemetry Transport (MQTT) protocol, or may also be in other transmission modes, which is not limited in this application.

After receiving the request of the home network management system, the gateway agent may return the device information of the access device included in the target lan shown in table 1 below, where the device information may include RSSI information, as follows:

TABLE 1

Device name	Device MAC address	Device IP address	RSSI information	\8230; (other information)
					Access device 1	MAC Address 1	IP address 1	RSSI_1	……
Access device 2	MAC Address 2	IP address 2	RSSI_2	……
					……	……	……	……	……
Access device N	MAC address N	IP address N	RSSI_N	……

It should be noted that table 1 is an implementation manner of acquiring RSSI information by a network device shown in this application, and the specific implementation manner of acquiring RSSI information by a network device is not limited in this application. It can be understood that the corresponding access device can be determined according to the "device name", "device MAC address", and "device IP address", so that subsequent analysis can be performed according to the RSSI information corresponding to the access device. The other information in table 1 may be other types of information transmitted according to actual situations, such as the acquisition time of RSSI information, the allocation time of DHCP client information of the access device, and the like.

When the method is implemented, the network equipment acquires the RSSI information of N access equipment in the target local area network so as to evaluate the quality of network signals of the target local area network, and the signal intensity of the access equipment at different moments is different along with the information such as the use state, the position and the like of the access equipment, so that larger signal intensity fluctuation may exist. It can be understood that the more stable the signal strength of the access device, the more accurate the result obtained by the network device. Optionally, the network device may select the RSSI information that the access device satisfies the specified condition for analysis.

Fig. 4 is a signal diagram illustrating that a network device acquires RSSI information of an access device according to an embodiment of the present application, and the access device 1, the access device 2, and the access device 3 are taken as examples for description. When the application is implemented, the network device may periodically receive M sub-RSSIs reported by the N access devices, respectively, and the acquisition time corresponding to each sub-RSSI, where M is a positive integer. In this way, the network device may obtain the signal diagram shown in fig. 4 according to the sub-RSSI information corresponding to each access device, and as can be seen from the diagram, the signal strength of each access device at different times may have certain fluctuation. It can be understood that, in a time period when the signal strength of the access device has a large fluctuation, the evaluation result of the network device may also have a relatively obvious change; and in a time period when the signal strength of the access device has small fluctuation, the evaluation result of the network device is stable, for example, 0: 00.

in order to obtain the evaluation result more accurately, the network device selects information meeting the requirement from the received sub-RSSI information of each access device at multiple acquisition moments as a sample to perform analysis processing, and further obtains the RSSI information of each access device to continue to evaluate the signal quality of the target local area network. Taking the processing of the ith access device (i may take a positive integer from 1 to N) by the network device as an example, the processing procedure of the network device on other access devices is similar.

The process flow may include the steps of:

a1, the network device divides the M sub-RSSIs into a plurality of time slot groups based on the acquisition time corresponding to the M sub-RSSIs respectively reported by the ith access device. Alternatively, for example, the method can be performed according to a time period group of every three hours, such as 0 to 3; or divide different time period groups according to other step sizes, for example, every two hours or every hour is taken as a time period group, which is not limited in the present application.

A2, the network device determines the dispersion of the plurality of sub-RSSIs included in each time period group. The time period group with smaller dispersion degree indicates that the signal intensity of the access equipment in the time period is relatively stable, namely the fluctuation is smaller; conversely, the signal strength of the access device during this period is less stable, i.e., fluctuates more.

The network device may employ various possible embodiments to determine the dispersion of the plurality of sub-RSSIs included in each time period group. Optionally, the dispersion may be one or a combination of coefficient of variation of fluctuation (CV), a difference between the maximum RSSI and the minimum RSSI, a variance, and the like, or may also be determined by other information, which is not limited in this application. Fig. 5 is a schematic diagram of determining the dispersion according to an embodiment of the present application, which takes the access device 4 and the access device 5 as an example. As can be seen from the content shown in fig. 5, the fluctuation CV of the access device 4 is smaller than that of the access device 5, so the signal strength fluctuation of the access device 4 is more stable; the variance of the access device 4 is smaller than that of the access device 5, so that the signal intensity fluctuation of the access device 4 is more stable; and, the difference between the maximum RSSI and the minimum RSSI of the access device 4 is smaller than that of the access device 5, so the signal strength fluctuation of the access device 4 is more stable.

In an optional implementation manner, if the dispersion is a fluctuation CV, the network device uses a time period group, in which fluctuation CVs of a plurality of sub-RSSIs included in a plurality of time period groups are smaller than a first threshold value, as the target time period group. For example, assuming that the first threshold value is-0.2, fig. 6 is a schematic diagram of another method for determining the dispersion according to an embodiment of the present application, in which the dispersion is determined by the fluctuation CV. Illustratively, the network device determines that the fluctuation CV of the access device 1 in the time period group 1 (0-3; and the fluctuating CV in period group 3 (6 to 9); thereby, the period 1, or the period 2, or the period 1+ period group 2 can be selected as the target period group. The fluctuation CV of the access device in each time period group can be obtained by comparing the dispersion of the RSSI of each acquisition time with the RSSI of the previous acquisition time.

Another optional implementation manner is that, if the dispersion is a difference between a maximum RSSI and a minimum RSSI, the network device uses a time period group, in which a difference between the maximum RSSI and the minimum RSSI of a plurality of sub-RSSIs included in the time period groups is smaller than a second threshold, as the target time period group. For example, in combination with the content shown in fig. 4, the embodiment of the present application may query the maximum RSSI and the minimum RSSI in each time slot group, and further calculate the difference between the maximum RSSI and the minimum RSSI. It can be understood that, in a time slot group, the maximum amplitude of the fluctuation may be determined according to a difference between the maximum RSSI and the minimum RSSI, and if the difference between the maximum RSSI and the minimum RSSI is smaller than a certain value, it indicates that the differences between the values of the multiple sub-RSSIs in the time slot are small, and it may also be understood that the signal strength of the access device in the time slot group is relatively stable.

In another optional implementation manner, if the dispersion is a variance, the network device sets a time period group, in which the variance of a plurality of sub-RSSIs included in the time period groups is smaller than a third threshold value, as the target time period group. Similar to the principle of fluctuating CV, the variance may be used to measure the degree of deviation between each sub-RSSI in each time period group and the mathematical expectation. In this way, if the variance of the plurality of sub-RSSIs included in a time slot group is smaller, it indicates that the signal strength of the access device in the time slot group is more stable.

And A3, the network equipment selects a target time period group according to the dispersion of a plurality of sub-RSSIs contained in the time period groups.

For example, one or more time period groups may be selected as the target time period group in the embodiments of the present application. Alternatively, the network device may select the time period group with the smallest dispersion as the target time period group, for example, if the fluctuation CV of the time period 2 in fig. 6 is smallest, then select the time period group 2 as the target time period group; or alternatively, the network device may also select a plurality of time period groups with dispersion satisfying the threshold requirement as in A2 as the target time period group, for example, if both the time period 1 and the time period 2 in fig. 6 satisfy the threshold requirement with the fluctuation CV smaller than-0.2, the time period group 1+ the time period group 2 is selected as the target time period group.

A4, the network equipment obtains the RSSI of the ith access equipment according to a plurality of sub-RSSIs contained in the target time slot group; and i is taken as any one positive integer from 1 to N.

Illustratively, the network device normalizes a plurality of sub-RSSIs included in the target time slot group to obtain an RSSI of the ith access device. For example, assuming that the network device selects n (n is a positive integer) time period groups as the target time period group, each time period group includes M sub-RSSIs, and the network device may perform normalization processing such as averaging or weighted averaging on nM sub-RSSI information, or may also use other normalization processing, which is not limited in this application. In this way, RSSI information may be obtained that characterizes the signal strength of the access device.

S302, the network equipment analyzes the N RSSIs, and divides the target local area network into a plurality of area ranges, wherein each area range corresponds to the RSSI in different value ranges.

For example, the network device clusters the N RSSIs to obtain a plurality of cluster categories, where the clustering process may use algorithms such as k-means (k-means) and k-center, and the application is not limited in this application. Then, the network device divides the target local area network into the plurality of area ranges according to the plurality of cluster categories, and the plurality of cluster categories correspond to the plurality of area ranges one to one.

For example, fig. 7 is a schematic diagram illustrating division of an area range of an access device layout method according to an embodiment of the present application. Assuming that N is 5, the processing based on S301 may obtain radio signal strengths of 5 access devices as-80 dBm (e.g., the access device is a smart screen), -78dBm (e.g., the access device is a handset 3), -62dBm (e.g., the access device is a handset 2), -60dBm (e.g., the access device is a handset 1), -40dBm (e.g., the access device is a router), respectively; assuming that 5 access devices are divided into three area ranges (such as an area A, an area B and an area C), if a k-means clustering mode is adopted, and-80 dBm, -60dBm and-40 dBm can be selected as a clustering center, the three area ranges can be obtained through division according to the wireless signal intensity of the 5 access devices; each zone range may represent a class with a different signal quality based on the RSSI corresponding to the different value ranges. The area C can contain an intelligent screen with signal strength of-80 dBm and a mobile phone 3 with signal strength of-78 dBm, so that the value range of the area C is near-80 dBm, and the final result can be determined according to clustering of a target local area network; the area B can comprise a mobile phone 2 with signal intensity of-62 dBm and a mobile phone 1 with signal intensity of-60 dBm, so that the value range of the area B is near-60 dBm; area a may contain routers with signal strength of-40 dBm, so the range of values for area a is around-40 dBm.

Thus, the network device can obtain the area range of each access device by dividing the area ranges of the N access devices. And according to the RSSI corresponding to different value ranges in each area range, the signal strength characteristic of each area range can be determined. As shown in fig. 7, it can be determined that the area a can be used to characterize the area range of "good signal", the area B can be used to characterize the area range of "in signal", and the area C can be used to characterize the area range of "poor signal". In addition, when the application is implemented, the network device may further generate a matched visual view, for example, the content shown in fig. 7, for obtaining the region range division result, so that a technician can conveniently perform troubleshooting, abnormality analysis, and the like on the wireless signal quality of the target local area network based on the visual view.

And S303, the network equipment evaluates the signal quality of the target local area network according to the plurality of area ranges to obtain an evaluation result.

S304: and the network equipment generates a target layout mode for at least one access equipment according to the evaluation result.

For example, the evaluation result may be customized individually according to an actual situation, and the coverage of the target local area network or the signal states of the N access devices may be analyzed according to the evaluation result, so that a targeted target layout manner may be generated. The following is illustrated by several possible scenarios:

in scenario 1, the network device may further determine whether each area range is an active area based on a plurality of area ranges divided into the target local area network. It can be understood that the active region may be a region where the user has a higher demand in the target lan, and therefore the signal quality of the active region has a greater influence on most users in the target lan. Thus, by evaluating the signal quality of the active region, the evaluation result of the target local area network and the target layout mode can be obtained.

For example, fig. 8 is an active area schematic diagram of an access device layout method according to an embodiment of the present application. The active area threshold is taken as an example that the number of the devices is greater than or equal to 3, or the network duration of the access device is greater than or equal to 30 minutes.

Optionally, if the network device identifies that the number of access devices included in the first area range is greater than or equal to a first number threshold (assumed to be 3), or identifies that the network duration of the access devices in the first area range is greater than or equal to a first duration threshold (assumed to be 30 minutes), determining the first area range as an active area. Wherein the first area range is any one of the plurality of area ranges.

Based on the above embodiment, if the RSSI included in the active region is lower than the first RSSI threshold, which indicates that the signal quality of the active region is not good, the first target layout manner may be generated. Wherein, the first target layout mode may include one or a combination of the following modes:

1) And for an Access Point (AP) contained in the target local area network, adjusting the distance between the AP and at least one access device contained in the active area. With reference to the content shown in fig. 7, the gateway may be an AP in the target lan, and if the area C is determined as an active area and the signal quality is not good, the distance between the gateway and the access device in the area C may be adjusted, for example, the gateway may be placed beside the smart screen.

2) Adding one or more APs to the active region. Continuing with the description of fig. 7 and the assumptions of the foregoing, it is also possible to add a new AP to the area C, for example, add a new router near the smart screen, and set the smart screen and the mobile phone 3 to connect to the new router.

It should be noted that there may be other target layout manners for the evaluation result of poor signal quality in the active region, for example, manners such as increasing transmission bandwidth of the AP, and the specific implementation of the target layout manner is not limited in the present application.

Alternatively, similar to the implementation manner of the network device to determine the active area, the network device may further determine the second area range as the inactive area when recognizing that the number of the access devices included in the second area range is smaller than a second number threshold, or recognizing that the network duration of the access devices in the second area range is smaller than a second duration threshold. Wherein the second area range is any one of the plurality of area ranges. The second number threshold may be the same as the first number threshold, or may be smaller than the first number threshold. Similarly, the second duration threshold may be the same as the first duration threshold, or may be smaller than the first duration threshold. For example, in connection with the content shown in fig. 8, the first number threshold is 3, and the second number threshold may be set to 2. In this way, by determining the wireless signal strength of the inactive area and the active area, if it is determined that the wireless signal strength of the inactive area is strong and the wireless signal strength of the active area is poor, the access device in the inactive area can be determined, and prompt information and the like with good signals around the access device can be sent to the user.

Based on the above description in scenario 1, the network device may also determine the coverage of the target lan according to the area coverage and the number of access devices in each area coverage. As shown in table 2 below:

TABLE 2

Region scope identification	Range of RSSI values	Number of access devices involved
			Region 1	First value range	1
Region 2	Second value range	2
			Region area 3	Third range of values	2
Region area 4	Fourth value range	4

In table 1, assuming that the first value range > the second value range > the third value range > the fourth value range (where the RSSI of the access device is larger, the signal quality of the access device is higher), a larger number of access devices can be included in the area range with the worst signal quality, and thus an evaluation result with a poor coverage condition of the target area range can be obtained. It can be understood that if the signal strength of the area range in which the access device is located is better, which is included in the target lan; in other words, the area range with poor signal quality in the target local area network does not contain the access equipment, so that the target local area network can be determined to have better coverage; conversely, if there are many access devices in the target lan within the area with poor signal strength, it may be determined that the target lan is under poor coverage. It should be noted that the specific determination manner of the evaluation result may be determined according to actual situations.

Scenario 2, the network device may determine the signal status of each access device according to the area range and the area range where each access device is located. With continued reference to the example in table 2, assuming that the area range 1 where the access device 1 is located is the first value range, it may be determined that the signal state of the access device 1 is better; if the area range 4 in which the access device 2 is located is the fourth value range, it may be determined that the signal state of the access device 2 is poor.

In an alternative embodiment, the network device may perform signal quality evaluation on the access device through the following steps:

and B1, the network equipment receives an evaluation request for first access equipment, wherein the first access equipment is any one of the N access equipment. For example, when there is a network card pause problem during the use of the mobile phone, the user may initiate an evaluation request, for example, by dialing a customer service phone or a specific portal.

And B2, the network equipment determines a third area range in which the first access equipment is positioned according to the evaluation request, wherein the third area range is any area range in the plurality of area ranges. Through the processing in S302, the area range shown in fig. 7 can be obtained, and the network device can determine the area range where the first access device is located, assuming that the first access device is the mobile phone 3 in fig. 7, and the third area range is the area C.

And B3, the network equipment determines that at least one RSSI (received signal strength indicator) in the third area range is smaller than a second RSSI threshold value, and determines that the signal quality of the first access equipment is the first quality as the evaluation result. Assuming that the second RSSI threshold is-70 dBm, the network device determines that the handset 3 has a network stuck problem due to poor network quality.

For example, when the evaluation result is that the signal quality of the first access device is a first quality, the network device may generate a second target layout manner; wherein the second target layout mode comprises one or a combination of the following modes:

1) And adjusting the distance between the first access equipment and the AP connected with the first access equipment. It can be understood that by adjusting the distance between the first access device and the connected AP, the signal attenuation, obstacles, etc. of the first access device can be reduced, and thus the signal quality can be enhanced.

2) And adjusting the distance between the first access equipment and a gateway connected with the first access equipment. In a similar manner as the first access device connects to the AP, signal quality may also be enhanced by moving closer to the distance between the first access device and the connected gateway.

3) And improving the transmission bandwidth of the AP or the gateway connected with the first access equipment. It can be understood that, in a scenario where the transmission bandwidth of the AP or the network is increased, the actual available bandwidth allocated to the first access device may be increased, so as to also improve the signal quality of the first access device.

And B4, the network equipment determines that the RSSI contained in the third area range is greater than or equal to the second RSSI threshold value, and determines that the evaluation result is that the signal quality of the first access equipment is the second quality.

It should be noted that, for the evaluation result of poor signal quality of the first access device, other target layout manners may also exist, for example, a manner of adding a new AP is added, and the specific implementation of the target layout manner is not limited in the present application.

In addition, the embodiment of the present application may further include other possible scenarios, which may be designed according to actual situations, and are not listed here one by one.

In order that the user may know the network quality of the used local area network in time, the network device may further trigger sending of a prompt message to at least one target access device included in the target local area network, where the prompt message may include one or a combination of the following information: the evaluation result and the target layout mode. The target access device may be any one of the N access devices, or the target access device may also be a device independent of the N access devices. For example, assuming that the target lan includes access device 1, access device 2, and access device 3, the network device may send a prompt message to access device 1; alternatively, the network device may also send the notification information to each of the access device 1, the access device 2, and the access device 3. The prompt information may be implemented in the form of a short message, a telephone, a pop-up window, or the like, which is not limited in the present application.

According to the access device layout method provided by the embodiment of the application, the network device collects and analyzes RSSI information of the access devices contained in the target local area network, and the target local area network is divided into a plurality of logical area ranges corresponding to RSSI of different value ranges based on the RSSI, so that the signal quality can be evaluated based on the divided area ranges and the area range where each access device is located, and the reason that the signal quality of the access devices is poor can be accurately analyzed. For example, the access device may be in a poor wireless signal strength in the area, or in a poor wireless signal coverage in the target lan, rather than in the quality of the access device itself. And, through the signal quality assessment of the network equipment to the target LAN, can also produce the corresponding target layout mode according to the result of assessment. Therefore, technicians can be prevented from going home many times, and a preliminary judgment result can be obtained based on analysis of the network equipment, so that the efficiency, the accuracy and the like of identifying the problems of poor coverage or weak signals of the access equipment in the local area network can be improved.

Based on the same technical concept of the foregoing access device layout method, an embodiment of the present application further provides an access device layout apparatus 900, which may be disposed on a network device, as shown in fig. 9. The access device placement apparatus 900 includes: the transceiver 901 and the processing unit 902 may be configured to implement the method described in the above method embodiment. The optional transceiver 901 and the processing unit 902 may be connected to each other through a communication line 903; the communication line 903 may be a Peripheral Component Interconnect (PCI) bus, an Extended Industry Standard Architecture (EISA) bus, or the like. The communication line 903 may be divided into an address bus, a data bus, a control bus, etc. For ease of illustration, only one thick line is shown in FIG. 9, but this does not indicate only one bus or one type of bus.

The transceiver 901 is configured to acquire N RSSI (received signal strength indicator) of N access devices included in a target lan, where the N access devices are in one-to-one correspondence with the N RSSI, and N is a positive integer; the access equipment has higher signal quality when the RSSI of the access equipment is higher. The processing unit 902 is configured to analyze the N RSSIs, and divide the target local area network into a plurality of area ranges, where each area range corresponds to an RSSI in a different value range; evaluating the signal quality of the target local area network according to the plurality of area ranges to obtain an evaluation result; and generating a target layout mode for at least one access device according to the evaluation result.

The processing unit 902 may specifically be configured to cluster the N RSSIs to obtain multiple cluster categories when the target local area network is divided into multiple area ranges; and dividing the target local area network into the plurality of area ranges according to the plurality of cluster categories, wherein the plurality of cluster categories correspond to the plurality of area ranges one by one.

When the transceiver 901 obtains N RSSIs of N access devices included in a target lan, the transceiver may be specifically configured to periodically receive M sub-RSSIs reported by the N access devices respectively and an acquisition time corresponding to each sub-RSSI, where M is a positive integer. Aiming at an ith access device, executing acquisition time corresponding to M sub-RSSIs respectively reported by the ith access device, dividing the M sub-RSSIs into a plurality of time slot groups, and determining the dispersion of the plurality of sub-RSSIs contained in each time slot group; selecting a target time period group according to the dispersion of a plurality of sub-RSSIs contained in the time period groups, and obtaining the RSSI of the ith access device according to the plurality of sub-RSSIs contained in the target time period group; wherein, i is taken as any one positive integer from 1 to N.

Wherein the dispersion may include, but is not limited to including, one or a combination of the following information: coefficient of variation CV of fluctuation, difference between maximum RSSI and minimum RSSI, variance, etc. The processing unit 902 may be specifically configured to, when a target time period group is selected according to the dispersion of the multiple sub-RSSIs included in the multiple time period groups, use, as the target time period group, a time period group in which the fluctuation variation coefficient CV of the multiple sub-RSSIs included in the multiple time period groups is smaller than a first threshold value if the dispersion is the fluctuation CV. Or may be specifically configured to, if the dispersion is a difference between the maximum RSSI and the minimum RSSI, regard, as the target time period group, a time period group in which a difference between the maximum RSSI and the minimum RSSI of the plurality of sub-RSSIs included in the plurality of time period groups is smaller than a second threshold. Or, in particular, if the dispersion is the variance, a time slot group in which the variance of the multiple sub-RSSIs included in the multiple time slot groups is smaller than a third threshold value is used as the target time slot group. It should be noted that the determination method of the dispersion may also include other implementation methods, and this application is not limited to this.

In an optional implementation manner, when the processing unit 902 obtains the RSSI of the ith access device according to the multiple sub-RSSIs included in the target time slot group, the processing unit may be specifically configured to perform normalization processing on the multiple sub-RSSIs included in the target time slot group to obtain the RSSI of the ith access device.

In the above embodiment, when the processing unit 902 performs the normalization process on the plurality of sub-RSSIs included in the target time segment group, the processing unit may be specifically configured to perform an averaging operation or a weighted averaging operation on the plurality of sub-RSSIs included in the target time segment group. It should be noted that the normalization processing method may also include other implementation methods, which are not limited in the present application.

In a possible example, when the processing unit 902 evaluates the signal quality of the target local area network according to the multiple area ranges, specifically to identify that the number of access devices included in a first area range is greater than or equal to a first number threshold, or identify that the network duration of the access devices in the first area range is greater than or equal to a first duration threshold, determine the first area range as an active area; if the number of the access devices contained in the second area range is smaller than a second number threshold value, or the network duration of the access devices in the second area range is smaller than a second duration threshold value, determining the second area range as an inactive area; wherein the first area range or the second area range is any one of the plurality of area ranges.

In the above example, when the processing unit 902 generates the target layout manner for at least one access device according to the evaluation result, the processing unit may be specifically configured to generate a first target layout manner if the RSSI included in the active region is lower than a first RSSI threshold, where the first target layout manner includes, but is not limited to, one or a combination of the following manners: for an Access Point (AP) contained in the target local area network, adjusting the distance between the AP and at least one access device contained in the active area; adding one or more APs to the active region; and so on. It should be noted that the first target layout manner may also include other implementation manners, which are not limited in this application.

In another possible example, when the processing unit 902 evaluates the signal quality of the target local area network according to the multiple area ranges, the processing unit may be specifically configured to receive an evaluation request for a first access device, where the first access device is any access device in the N access devices; determining a third area range in which the first access device is located according to the evaluation request, wherein the third area range is any one of the area ranges; determining that at least one RSSI (received signal strength indicator) in the third area range is smaller than a second RSSI threshold value, and determining that the evaluation result is that the signal quality of the first access equipment is first quality; and determining that the RSSI contained in the third area range is greater than or equal to the second RSSI threshold value, and determining that the evaluation result is that the signal quality of the first access equipment is the second quality.

In the above example, when the processing unit 902 generates the target layout manner for the first access device according to the evaluation result, the processing unit may specifically be configured to generate a second target layout manner when the evaluation result is that the signal quality of the first access device is a first quality; wherein the second target layout manner includes, but is not limited to, one or a combination of the following manners: adjusting the distance between the first access equipment and the AP connected with the first access equipment; adjusting the distance between the first access equipment and a gateway connected with the first access equipment; improving the transmission bandwidth of the AP or the gateway connected with the first access equipment; and the like. It should be noted that the second target layout manner may also include other implementation manners, which are not limited in this application.

In addition, the transceiver 901 may be further configured to send a prompt message to at least one target access device, where the prompt message includes, but is not limited to, one or a combination of the following: the evaluation result and the target layout mode; the target access device is any one of the N access devices, or the target access device is a device independent of the N access devices.
