Description

Method for identifying deployment position of access point and position identification equipment

Technical Field

The embodiment of the application relates to the technical field of positioning, in particular to a method for identifying deployment positions of access points and position identification equipment.

Background

A wireless fidelity (Wi-Fi) network comprises a terminal and an access point. Generally, a terminal connects to an access point through Wi-Fi to access a network. In a home scene, the access point is deployed by a user lacking professional network knowledge, so that the indoor overall Wi-Fi coverage quality is affected, and the user service experience is further affected. In addition, the telecom operator cannot know the deployment situation of the access point in the user home, so that the operator is hindered from optimizing the network for the user.

Therefore, there is an urgent need for a solution that can determine the deployment location of the access point according to the signal between the terminal and the access point, so that the operator can obtain the basis for optimizing the in-home network of the user.

Disclosure of Invention

The embodiment of the application provides a method for identifying the deployment position of an access point and position identification equipment, which are used for determining the specific deployment position of the access point in a family scene according to signals between a terminal and the access point.

In a first aspect, the present application provides a method for identifying an access point deployment location, which may be applied in a home scenario to identify a room type of a location where an access point is located, or in other scenarios where multiple rooms are present and isolated from each other. In the method, a location identification device first obtains a signal strength value and a throughput rate between an access point and a plurality of terminals, wherein the signal strength value is used for indicating the strength of a signal between the terminal and the access point, and the throughput rate is used for indicating the transmission rate of uplink or downlink traffic between the terminal and the access point. Then, the location identification device determines the type of the room in which the at least one terminal is located according to the signal strength value and the throughput rate. Then, the location identification device determines the room type of the access point according to the room type of the terminal and the location relationship between the terminal and the access point.

The location identification device may be a home gateway (e.g., an Optical Network Terminal (ONT)) deployed near a home of a user, or may be a local side device (e.g., an Optical Line Terminal (OLT)) in a Passive Optical Network (PON) system, or may be a server or a centralized processing unit arranged in an operator room or in a cloud. Optionally, the method for identifying the deployment location of the access point may be further executed by an access point in the user home, and at this time, after the access point determines the type of the room where the access point is located, the access point sends the type of the room to the home gateway, the office device, or the centralized processing unit, so that the home gateway, the office device, or the centralized processing unit sends the type of the room where the access point is located to the device on the operator side, so that the operator can obtain a basis for optimizing the network inside the user home.

In addition, the signal strength value may be an uplink signal strength value from the terminal measured by the access point, or may be a downlink signal strength value from the access point measured by the terminal, and the present application is not limited thereto.

In this embodiment, the type of the room in which the terminal is located can be determined according to the signal strength value and the throughput rate of the terminal. Since the signal strength value of the terminal can reflect the relative position relationship between the terminal and the access point, the type of the room in which the access point is located can be determined according to the type of the room in which the terminal is located. In this embodiment, the signal strength value and the throughput rate of the terminal can be directly obtained by the location identification device without user feedback, so that the room type of the access point inside the home of the user can be known without user feedback, and an operator can obtain a basis for optimizing the network inside the home of the user.

In an alternative embodiment, the determining, by the location identification device, a type of a room in which the at least one terminal is located according to the signal strength value and the throughput rate includes: the position identification equipment determines at least one terminal type of the terminal according to the signal strength value and the throughput rate of the terminal; the position identification equipment receives a first association rule corresponding to the access point, wherein the first association rule comprises an association relation between the terminal type and the room type; the position identification device determines the room type of the terminal according to the terminal type of the terminal and the first association rule.

In this embodiment, the location identification device can determine the type of the terminal according to the signal strength value and the throughput rate of the terminal, and the location identification device can receive a first association rule corresponding to the access point, where the first association rule includes an association relationship between the terminal type and the room type, and the room type is used to indicate a room in which the terminal of the terminal type is likely to be used. Therefore, the location identification device can determine the type of the room in which the terminal is located according to the terminal type of the terminal and the first association rule.

For example, if the terminal type is a video terminal (e.g., a television), the room type corresponding to the terminal type is a living room; if the terminal type is a meter reading type terminal (e.g., an electric meter, a gas meter, etc.), the room type corresponding to the terminal type is a kitchen. In practical applications, the association relationship between the terminal type and the room type may be adjusted according to different home users, and is not limited herein.

In a specific embodiment, the first association rule is received from the operator-side device, and the operation and maintenance manager may input the first association rule through the first user interface. For example, the operator-side device may be a server managing the access point, and the first user interface is located in the server managing the access point, which may be understood as a user interface located in the operator-side device.

In this embodiment, since the location identification device can receive the first association rule from the outside, the location identification device has a criterion for identifying the type of the room in which the terminal is located, which is beneficial for the location identification device to determine the type of the room in which the terminal is located according to the type of the terminal.

In an optional implementation manner, the determining at least one terminal type of the terminal according to the signal strength value and the throughput rate of the terminal includes: the position identification equipment receives the through-wall loss value; the position identification equipment divides a plurality of signal strength values of a plurality of terminals into at least one set according to the through-wall loss value, and each set comprises at least one signal strength value of one terminal; the position identification equipment determines that the terminal corresponding to the set is a mobile terminal or a fixed terminal according to the distribution characteristics of the at least one set; and the position identification equipment determines the terminal type of the mobile terminal or the terminal type of the fixed terminal according to the throughput rate.

The distribution characteristics of the sets can also be understood as the number of the sets and the position distribution relationship of a plurality of sets in the coordinate system.

In this embodiment, it is proposed that the location identification device is capable of receiving a through-wall loss value from the operator-side device, where the through-wall loss value is a loss value of a signal after the signal passes through an obstacle, and generally, the through-wall loss value can be measured by a difference between a signal strength value before the signal passes through a wall and a signal strength value after the signal passes through the wall. In this embodiment, the location identification device classifies the signal strength values of different terminals according to the magnitude of the signal strength value, similar or identical signal strength values of the same terminal are classified into one set, and signal strength values of the same terminal with a larger difference are classified into different sets. Therefore, the position identification equipment can determine that the terminal corresponding to the set is a mobile terminal or a fixed terminal according to the distribution characteristics of the at least one set. For example, if the signal strength value of the same terminal is only divided into one set, the location identification device determines that the terminal is a fixed terminal; and if the signal strength values of the same terminal are divided into a plurality of sets, and the difference between the signal strength values in different sets is greater than or equal to the through-wall loss value, the position identification equipment determines that the terminal is a mobile terminal.

In an alternative embodiment, the method further comprises: and determining the position relation between the terminal corresponding to the set and the access point according to the distribution characteristics of the at least one set.

In this embodiment, since the signal is through the wall and the wall-through loss is generated, the more the wall surface between the access point and the terminal is, the more the signal is attenuated. Therefore, the location identification device can classify a plurality of signal strength values according to the wall-through loss value to distinguish whether the wall-through loss exists between the terminal corresponding to the signal strength value and the access point and whether the wall-through loss exists between the terminal and the access point for a plurality of times. That is, the partition set based on the wall-propagation loss can enable the location identifying device to determine the location relationship between the terminal corresponding to the set and the access point according to the plurality of sets. Wherein, the position relation between the terminal and the access point comprises: the terminal is located in the same room as the access point or the terminal is located in a different room from the access point.

In an optional implementation manner, the determining, by the location identification device, the type of the room in which the access point is located according to the type of the room in which the terminal is located and the location relationship between the terminal and the access point includes: and when the terminal type of the terminal is a fixed terminal and the access point are positioned in the same room, determining that the room type in which the terminal is positioned is the room type in which the access point is positioned.

In this embodiment, it is proposed that if the location identification device can determine the type of the room in which a certain fixed terminal is located, and the fixed terminal and the access point are located in the same room, the type of the room in which the fixed terminal is located is the type of the room in which the access point is located.

In an optional embodiment, the first association rule further includes an association relationship between the mobile terminal and the room type at a target time, wherein the target time is associated with a movement track of a user using the mobile terminal; determining at least one room type in which the terminal is located according to the terminal type of the terminal and a first association rule, wherein the method comprises the following steps: and determining the type of the room where the mobile terminal is located at the target time according to the target time and the first association rule.

In this embodiment, it is proposed that the signal strength value may be a signal strength value from a mobile terminal, and then the location identification device determines that the terminal is a mobile terminal according to the signal strength value. The moving track of the mobile terminal is connected with the activity track of the user or the behavior habit of the user. That is, the movement trajectory of the mobile terminal may be determined according to a change in the activity trajectory of the user over time (i.e., the behavior habit of the user). For example, if the target time period is a lunch time period (e.g., 12:00-13:00), the room type corresponding to the target time period is a restaurant. At this time, if the time (hereinafter referred to as a first time) corresponding to the signal strength value is just within the target time period, it is determined that the room type corresponding to the target time period is the room type in which the mobile terminal is located at the first time. As another example, if the target time period is a rest period (e.g., 22:00-06:00), the room type corresponding to the target time period is a bedroom. At this time, if the time (hereinafter referred to as a second time) corresponding to the signal strength value is just within the target time period, it is determined that the room type corresponding to the target time period is the room type in which the mobile terminal is located at the second time.

In an optional embodiment, the determining the type of the room in which the access point is located according to the type of the room in which the terminal is located and the location relationship between the terminal and the access point includes: and when the time when the terminal and the access point are positioned in the same room is the first time, determining that the type of the room in which the mobile terminal is positioned at the first time is the type of the room in which the access point is positioned.

In this embodiment, it is proposed that the location identification device can receive the house type map, and determine the room type of the weak coverage area according to the house type map and the type of the room in which the access point is located, which is beneficial for an operator to provide a network optimization strategy for the user based on the room type of the weak coverage area.

In an alternative embodiment, the process of dividing, by the location identification device, the plurality of signal strength values of the plurality of terminals into at least one set according to the wall-through loss value may be implemented as follows:

the position identification equipment divides a plurality of signal intensity values of each terminal into at least one set by adopting a clustering algorithm according to preset clustering parameters, each set comprises at least one signal intensity value of the terminal, each set corresponds to one clustering center, and each terminal corresponds to at least one clustering center. Then, the location identification device determines at least one target cluster center from the plurality of sets of cluster centers, the target cluster center being a maximum value of the plurality of cluster centers. Then, the position identification device determines that the terminal corresponding to the set where the target clustering center is located and the terminal of the access point located in the same room.

There are various ways to determine the cluster center, for example, the cluster center is determined by a weighted average of all signal intensity values in the set, and the method is not limited herein.

In an alternative embodiment, the preset clustering parameter includes a minimum value of the number of signal strength values included in the set, and a distance between each of the signal strength values and the cluster center, where the distance between each of the signal strength values and the cluster center is a through-wall loss.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

A system architecture of the method for identifying an access point deployment location provided by the embodiment of the present application is described below:

fig. 1A is a system architecture diagram illustrating a method for identifying an access point deployment location according to an embodiment of the present invention. The system includes a location identification device 001, an access point 002, and a terminal 003. Wherein the location identifying device 001 is used to manage one or more access points 002. For example, the access point 002 receives information from the access point 002 and issues a control command or the like. Each access point 002 is connected to one or more terminals 003 via wireless fidelity (Wi-Fi) and performs data interaction with the aforementioned terminals 003 via Wi-Fi.

The access point 002 may be a router or optical modem that is in-home through an optical fiber. The terminal 003 can be a mobile terminal such as a mobile phone, a tablet personal computer, and an intelligent bracelet that is connected to the router or the optical modem via Wi-Fi, or an internet of things device or an industrial intelligent device such as a network television, a network monitoring device, and an indoor temperature control device.

In a possible scenario, the system architecture shown in fig. 1A may be embodied as a PON system architecture as shown in fig. 1B. The PON system includes an Optical Line Terminal (OLT) 101, an Optical Network Terminal (ONT) 102, and an access point 002. The optical line terminal OLT 101 is connected to an operator network through a network side interface, and the optical line terminal OLT 101 is connected to the optical network terminal ONT 102 through an Optical Distribution Network (ODN) including a splitter (splitter). The optical network terminal ONT 102 is connected to the aforementioned access point 002 by an optical fiber. At this time, the aforementioned location identification device 001 in fig. 1A may be the optical line terminal OLT 101 or the optical network terminal ONT 102 in fig. 1B. When the location identifying device 001 is the optical line terminal OLT 101, the optical network terminal ONT 102 may send information about an access point or a terminal, which is obtained from the access point 002, to the optical line terminal OLT 101, determine a room type of the location where the access point is located by the optical line terminal OLT 101, and send the room type of the location where the access point is located to the operator side device, so that the operator side device makes a decision on how to optimize the user home internal network. When the location identifying device 001 is the optical network terminal ONT 102, the location identifying device 001 is also often called a home gateway, and the optical network terminal ONT 102 determines the room type of the location where the access point is located according to the acquired information about the access point or the terminal, and sends the room type of the location where the access point is located to the operator side device.

In another possible scenario, the aforementioned location identifying device 001 may be a server or a centralized processing unit arranged in an operator room or in a cloud. The server or the centralized processing unit can acquire information about the access point or the terminal through the PON system, and determine the room type of the location where the access point is located according to the information about the access point or the terminal. Then, the room type of the position of the access point is sent to the operator side device, so that the operator side device can decide how to optimize the user home internal network.

There is also a possible scenario where the aforementioned location identification device 001 is integrated in a certain access point in the user's home. That is, the method for identifying the deployment location of the access point may be performed by an access point in the home of the user, and in this case, the access point may collect information about the access point or the terminal, and may determine the type of the room where the access point is located according to the information about the access point or the terminal, and then transmit the type of the room to the operator-side device through the PON system.

It should be understood that the foregoing scenarios are merely exemplary scenarios listed for describing the scheme of the present application, and in practical applications, the method for identifying the deployment location of the access point may also be applied to other scenarios, and the present application is not limited thereto.

As shown in fig. 2, for one embodiment of the method for identifying the deployment location of the access point proposed by the present application, in the method, the location identifying device performs the following steps:

step 201, obtaining a signal strength value and a throughput rate between an access point and a plurality of terminals.

Wherein the signal strength value is used to indicate the strength of the signal between the terminal and the access point. Generally, a larger signal strength value indicates a stronger signal between the terminal and the access point. Since the strength of the signal is inversely related to the distance between the devices (i.e., the distance between the access point and the terminal), the larger the signal strength value, the smaller the distance between the terminal and the access point. Therefore, the location identifying device can determine the location relationship between the terminal and the access point according to the signal strength value. In addition, the distance between the fixed terminal and the access point cannot be changed, so that the signal strength value between the fixed terminal and the access point cannot be changed suddenly; the distance between the mobile terminal and the access point may change, and thus, the signal strength value between the mobile terminal and the access point may change. Therefore, the location identifying device can determine whether the terminal connected with the access point is a mobile terminal or a fixed terminal according to the signal strength value.

It should be noted that the foregoing signal strength value may be measured by the terminal, and may also be measured by the access point. In an alternative embodiment, the signal strength value may be an uplink signal strength value from the terminal measured by the access point, and in this case, the signal strength value may be represented by a Received Signal Strength Indicator (RSSI), that is, a wideband received power over a channel bandwidth received by a reverse receiver in the access point. In another alternative embodiment, the signal strength value is a downlink signal strength value from the access point measured by the terminal, and in this case, the signal strength value may be represented by a received power (Rx), that is, a wideband received power received by a forward receiver in the terminal over a channel bandwidth. The present application is not limited in particular. For convenience of description, the uplink signal strength value from the terminal measured by the signal strength value as the access point will be described as an example.

It should also be noted that the location identifying device needs to acquire multiple signal strength values and multiple throughput rates of each terminal, and the measurement moments of the multiple signal strength values of the same terminal are periodically distributed. Taking the uplink signal strength value from the terminal measured by the access point as an example, the access point may measure the uplink signal strength value of the terminal and the throughput rate of the terminal every 1 minute, and then transmit a measurement result of a certain period of time (for example, the measured signal strength value and throughput rate of 2 hours) to the location identification device. In this case, the location identification device can obtain a plurality of signal strength values and a plurality of throughput rates of the same terminal at different measurement times. Similarly, the access point may measure different terminals at the same time, and transmit the measurement results including the signal strength value and the throughput rate with respect to a plurality of terminals to the location identifying device.

In addition, the terminal connected to the access point may be in an idle state or a traffic state. When the terminal is in a service state, a data packet for transmitting service data exists between the terminal and the access point, and the access point can determine the signal strength value and the throughput rate through the data packet; when the terminal is in an idle state, the access point may send a TCP test packet to the terminal, and determine the signal strength value and the throughput rate according to an Acknowledgement Character (ACK) frame (i.e., an ACK packet) replied by the terminal.

It should be noted that when the location identifying device processes a plurality of signal strength values, the plurality of signal strength values are all uplink signal strength values from the terminal or all downlink signal strength values from the access point.

In addition, the throughput (throughput) is used to indicate the transmission rate of uplink or downlink traffic between the terminal and the access point, and can also be understood as indicating the amount of data uploaded/downloaded by the network per unit time. Generally, the throughput rates of different types of terminals are not exactly the same. For example, a video-type terminal (e.g., a television or a projector) may download much more data than it uploads when in use; when the meter reading type terminal (such as a gas meter, an electric meter and the like) is used, the data uploading quantity and the data downloading quantity are small. Accordingly, the location identifying device may determine the terminal type of the terminal based on the throughput rate.

Step 202, determining the room type of the at least one terminal according to the signal strength value and the throughput rate.

Specifically, the location identifying device needs to determine the terminal type of at least one terminal according to the signal strength value and the throughput rate of the terminal. Then, the position identification device determines the room type of the terminal according to the terminal type of the terminal and the first association rule. Please refer to the related descriptions in steps 403 to 404 below for specific steps of determining the terminal type according to the signal strength value and the throughput of the terminal.

The first association rule is received by the position identification device from the operator side device, and the operation and maintenance manager can input the first association rule through a first user interface. For example, the operator-side device may be a server managing the access point, and the first user interface is located in the server managing the access point, which may be understood as a user interface located in the operator-side device.

The first association rule includes an association relationship between a terminal type and a room type. That is, after the location identification device determines the terminal type of the terminal, the location identification device may look up a room type corresponding to the terminal type in the first association rule based on the terminal type. Optionally, the first association rule may be a correspondence table stored in the location identification device, where the correspondence table includes different terminal types and a room type corresponding to each terminal type.

Illustratively, the first association rule may be as shown in table 1 below:

TABLE 1

Terminal type	Type of room
		Television receiver	Parlor
Monitoring camera	Parlor
		Gas meter	Kitchen cabinet
Water heater	Toilet

In the example shown in table 1, the first association rule includes terminal types of fixed terminals, wherein one fixed terminal corresponds to one room type. For example, when the location identification device determines that the terminal type of a certain terminal is a television, the location identification device may determine that the room type associated with the terminal type is a living room by searching the first association rule. For another example, when the location identification device determines that the terminal type of a certain terminal is a gas meter, the location identification device may determine that the room type associated with the terminal type is a kitchen by searching the first association rule.

Since there may be mobile terminals in the user's home in addition to the fixed terminals, and the type of room in which the mobile terminal is located changes due to the movement of the mobile terminal. Thus, the first association rule may comprise a target time period in addition to the terminal type of the terminal. The target time period is a time period associated with a specific room type, and represents that the user moves the mobile terminal to the room corresponding to the room type in the target time period.

Illustratively, the first association rule may also be as shown in table 2 below:

TABLE 2

In the example shown in table 2, the first association rule includes the target time period in addition to the terminal type and the room type of the mobile terminal. The mobile terminal will move with the user to a particular room during the target time period. For example, in the target time period of 23:00-06: 00', the user carries the smart bracelet to move to a bedroom for rest; in the target time period of 12:00-13: 00', the user carries the intelligent bracelet to move to a restaurant for lunch; and in the target time period of 15:00-17:00, the user carries the intelligent bracelet to move to the study room to read the book.

It should be understood that the first association rules of different user families may not be identical, and the operator-side device may adjust the first association rules according to the living habits of local users, which is not limited herein.

Step 203, determining the room type of the access point according to the room type of the terminal and the position relationship between the terminal and the access point.

In this embodiment, since the strength of the signal is inversely related to the distance between the devices (i.e., the distance between the access point and the terminal), the larger the signal strength value, the smaller the distance between the terminal and the access point. Thereby, the location relationship between the terminal and the access point can be determined from the signal strength value. The position relation between the terminal and the access point comprises that the terminal and the access point are located in the same room, or the terminal and the access point are located in different rooms.

In this embodiment, the types of the terminals are different, and the manner of determining the type of the room in which the access point is located is not completely the same.

If the terminal type of the terminal is a fixed terminal and the access point are located in the same room, the location identification device determines that the room type where the fixed terminal is located is the room type where the access point is located. Wherein, this fixed terminal can be any one kind fixed terminal such as aforementioned TV set, surveillance camera head, gas table and water heater. For example, if the location identification device determines that the terminal type is a television, the type of the room in which the television is located is a living room, and determines that the television and the access point are located in the same room, the location identification device may determine that the access point is located in the living room.

In addition, if the terminal type of the terminal is a mobile terminal, the location identification device further needs to check whether the measurement time corresponding to the signal strength value of the terminal is located in a certain target time period in the first association rule. If the measurement time corresponding to the signal strength value corresponding to the mobile terminal falls into a certain target time period, the room type corresponding to the target time period is the room type of the mobile terminal at the measurement time. If the terminal and the access point are located in the same room at the measurement time, the location identification device determines that the room type of the mobile terminal at the measurement time is the room type of the access point.

The foregoing describes a main flow of a method for identifying a deployment location of an access point, which is further described below with reference to specific examples. As shown in fig. 3, another embodiment of the method for identifying the deployment location of the access point proposed in the present application is that in the method, the location identifying device performs the following steps:

step 301, a measurement record is obtained from an access point, the measurement record comprising a signal strength value and a throughput rate.

Wherein the signal strength value is used to indicate the strength of the signal between the terminal and the access point. The throughput rate is used to indicate the transmission rate of uplink or downlink traffic between the terminal and the access point. Each signal strength value corresponds to a measurement instant, and each throughput rate also corresponds to a measurement instant. Generally, the access point measures the signal strength value and the throughput at the same time at a certain measurement time. Wherein the throughput rate comprises an uplink throughput rate and a downlink throughput rate. For example, the measurement record may be expressed as { signal strength value; a throughput rate; the moment of measurement }. For example, the measurement record may also be expressed as { signal strength value; an uplink throughput rate; a downlink throughput rate; measurement time }. For the description of the signal strength value and the throughput rate, reference may be made to the related description in step 201, and details are not described here.

Furthermore, since an access point may be connected to multiple terminals simultaneously, the measurement record may also include the identity of the terminals in order to distinguish signal strength values between the access point and different terminals. The identifier of the terminal may be represented by a MAC address of the terminal, an IP address of the terminal, or other characters or fields capable of identifying the terminal. Illustratively, the measurement record may be expressed as { terminal identity; a signal strength value; an uplink throughput rate; a downlink throughput rate; the moment of measurement }.

In addition, there may be multiple access points in the same user's home, and the measurement record may also include the identity of the access point in order to distinguish between different access points. The identifier of the access point may be represented by a MAC address or a Service Set Identifier (SSID). It should also be noted that if an access point supports multi-frequency modes, e.g., an access point may provide signals in the 2.4G band and signals in the 5G band simultaneously, then the access point may have two different SSIDs. Illustratively, the measurement record may be expressed as { access point identity; a terminal identification; a signal strength value; an uplink throughput rate; a downlink throughput rate; measurement time }.

For example, the measurement record between the access point and a certain terminal can be as shown in the following table 3:

TABLE 3

Optionally, the measurement record may further include an index indicating signal quality between the access point and the terminal, for example, a negotiation rate PHYRate, a packet loss rate, and the like, which is not limited in this application.

Step 302, determining a terminal type of at least one terminal according to the signal strength value and the throughput rate.

Specifically, the position identification device divides a plurality of signal strength values of a plurality of terminals into at least one set according to the wall-through loss value, and each set comprises at least one signal strength value of one terminal. Then, the position identification device determines that the terminal corresponding to the set is a mobile terminal or a fixed terminal according to the distribution characteristics of the at least one set. The through-wall loss value is a loss value of a signal after the signal passes through an obstacle, and can be generally measured by a difference between a signal strength value before the signal passes through a wall and a signal strength value after the signal passes through the wall. In this embodiment, the through-wall loss value is received by the location identification device from the operator-side device. The distribution characteristics of the sets can also be understood as the number of sets and the distribution relationship of the positions of a plurality of sets in the coordinate system.

Since the relative position between the fixed terminal and the access point does not change, the signal strength value between the fixed terminal and the access point only changes within a certain range, and does not change abruptly. Therefore, if the terminal is a fixed terminal, there should be only one set determined according to the plurality of signal strength values of the terminal, and each signal strength value of the terminal falls into the set. In addition, the relative position between the mobile terminal and the access point may change, and therefore, the signal strength value between the mobile terminal and the access point may change abruptly, for example, the difference between two signal strength values obtained at different measurement moments is greater than or equal to the aforementioned wall-through loss value. At this time, if the terminal is a mobile terminal, multiple sets can be determined according to multiple signal strength values of the terminal, and the signal strength values in different sets are greater than or equal to the through-wall loss value. Therefore, the location identification device can determine that the terminal is a mobile terminal or a fixed terminal according to the distribution characteristics of the set.

That is, the location identifying device classifies signal strength values of different terminals according to the magnitude of the signal strength value, similar or identical signal strength values of the same terminal are classified into one set, and signal strength values of the same terminal which are more different are classified into different sets. Therefore, the position identification equipment can determine that the terminal corresponding to the set is a mobile terminal or a fixed terminal according to the distribution characteristics of the at least one set. For example, if the signal strength value of the same terminal is only divided into one set, the location identification device determines that the terminal is a fixed terminal; and if the signal strength values of the same terminal are divided into a plurality of sets, and the difference between the signal strength values in different sets is greater than or equal to the through-wall loss value, the position identification equipment determines that the terminal is a mobile terminal.

Specifically, the location identifying device may divide the plurality of signal strength values into different sets by using any one of the following implementations:

in an optional implementation manner, the location identifying device divides a plurality of signal strength values of a certain terminal into at least one set by using a DBSCAN (dense-based clustering of applications with noise) clustering algorithm according to preset clustering parameters, where each set includes at least one signal strength value of the terminal, and each set corresponds to one clustering center. The preset clustering parameters comprise the minimum number of signal intensity values contained in a set and the distance between each signal intensity value and the clustering center, and the distance between each signal intensity value and the clustering center is the through-wall loss. Then, the location identification device determines that the terminal is a mobile terminal or a fixed terminal according to the number of the sets (or the number of the clustering centers).

In another optional implementation manner, the location identifying device divides a plurality of signal strength values of a certain terminal into at least one set by using a k-means clustering algorithm (k-means clustering algorithm) according to preset clustering parameters, where each set includes at least one signal strength value of the terminal, and each set corresponds to a clustering center. The preset clustering parameters comprise the number of the sets and the distance between each signal intensity value and the clustering center, and the distance between each signal intensity value and the clustering center is the through-wall loss. Then, the location identification device determines that the terminal is a mobile terminal or a fixed terminal according to the number of the sets (or the number of the clustering centers).

It should be noted that there are various ways to determine the cluster center, for example, the cluster center is determined by a weighted average of all the signal intensity values in the aforementioned set, and the method is not limited herein.

For example, if the location identification device classifies a plurality of signal strength values of a certain terminal to obtain a set 401 and a set 402 as shown in fig. 4A, the location identification device may determine that the terminal is a mobile terminal because the set 401 and the set 402 correspond to different signal strength values, respectively. For example, if the location identifying device classifies a plurality of signal strength values of a certain terminal to obtain only one set (i.e., set 403) as shown in fig. 4B, the location identifying device will determine that the terminal is a fixed terminal.

Then, the location identification device determines the terminal type of the mobile terminal or the terminal type of the fixed terminal according to the throughput rate. When the terminal is a fixed terminal, the types of the terminal include a video terminal (e.g., a television or a projector), a video monitoring terminal (e.g., a monitoring camera), a meter reading terminal (e.g., an electric meter or a gas meter), and the like. When the terminal is a mobile terminal, the type of the terminal comprises a mobile phone, a computer, an intelligent bracelet and other devices.

Specifically, the location identification device may determine the type of the fixed terminal or the type of the mobile terminal in the following manner:

for example, if the downlink throughput rate is high (e.g., the downlink throughput rate is higher than a first preset value) and the uplink throughput rate is low (e.g., the uplink throughput rate is lower than a second preset value), the location identification device determines that the terminal type of the fixed terminal is a video terminal. For example, if the downlink throughput rate is greater than 150Mbps and the uplink throughput rate is less than 30Mbps, the terminal type is determined to be a video terminal.

For example, if the uplink throughput rate is high (for example, the uplink throughput rate is greater than a first preset value) and the downlink throughput rate is low (for example, the downlink throughput rate is less than a second preset value), the location identification device determines that the terminal type of the fixed terminal is a video monitoring terminal. For example, if the uplink throughput is greater than 150Mbps and the downlink throughput is less than 30Mbps, it is determined that the terminal type is a video monitoring terminal.

For example, if both the uplink throughput rate and the downlink throughput rate are relatively small (for example, the uplink throughput rate is smaller than a third preset value, and the downlink throughput rate is smaller than a fourth preset value), the location identification device determines that the terminal type of the fixed terminal is a meter reading terminal. For example, if the uplink throughput rate is less than 20Mbps and the downlink throughput rate is less than 20Mbps, it is determined that the terminal type is a video monitoring terminal.

It should be understood that the foregoing first preset value, second preset value, third preset value and fourth preset value and may be adjusted by the operation and maintenance personnel according to different application scenarios, and specific values of the foregoing preset values are specifically defined herein.

In this embodiment, after the position identification device performs step 302, step 303 and step 304 are performed, respectively.

Step 303, receiving a first association rule corresponding to the access point, and determining a room type where the at least one terminal is located according to the terminal type of the terminal and the first association rule.

Wherein the first association rule comprises an association relation between a terminal type and a room type. Specifically, reference may be made to the related description in step 202, and details are not described here.

And step 304, determining the position relation between the terminal and the access point corresponding to the set according to the distribution characteristics of the at least one set.

Specifically, the location identifying device may divide the plurality of signal strength values into at least one set in the manner described in step 302, where each set includes at least one signal strength value of the terminal, and each set corresponds to one cluster center. If only one set is obtained in the manner described above and the cluster center of the set is greater than the wall-through loss value, the location identification device may determine that the terminal and the access point are located in the same room. If the method is adopted, a plurality of sets are obtained, and each set corresponds to one cluster center. At this time, the position identification device compares the maximum value in the plurality of clustering centers with the through-wall loss value, and if the maximum value in the clustering centers is greater than the through-wall loss value, the position identification device determines the time period corresponding to the clustering center, and the terminal and the access point are located in the same room.

It should be understood that there is no time sequence between step 303 and step 304, the location identification device may perform step 303 before step 304, the location identification device may perform step 304 before step 303, or the location identification device may perform step 303 and step 304 simultaneously. After the location identifying device has performed

steps

303 and 304, the location identifying device will perform step 305.

And 305, determining the room type of the access point according to the room type of the terminal and the position relationship between the terminal and the access point.

In this embodiment, if the terminal type of the terminal is a fixed terminal and the access point are located in the same room, the location identification device determines that the room type in which the fixed terminal is located is the room type in which the access point is located. In addition, if the terminal type of the terminal is a mobile terminal, and the measurement time corresponding to the signal strength value corresponding to the mobile terminal falls within a certain target time period, the room type corresponding to the target time period is the room type in which the mobile terminal is located at the measurement time. If the terminal and the access point are located in the same room at the measurement time, the location identification device determines that the room type of the mobile terminal at the measurement time is the room type of the access point. Specifically, please refer to the related description in step 203, which is not described herein again.

Step 306, receiving the house type map, and determining the room type of the weak coverage area according to the house type map and the room type of the access point.

Wherein the house type graph comprises a room type of each of the plurality of rooms and a positional relationship between the plurality of rooms. The house type graph can be provided by a user of a family where the access point is located, and can also be acquired from a network by the operator side equipment according to the name of a cell where the user is located.

For ease of understanding, fig. 4C is taken as an example for description. In the floor plan shown in fig. 4C, if it is determined that the type of the room in which the access point is located is the living room (i.e., the access point is located in the living room), the location identification device will find the type of the room far from the access point from the floor plan. For example, since the bedroom 2 is far from the living room, the location identification device may determine that the room type of the weak coverage area is the bedroom 2.

It should be appreciated that the manner in which the location identification device determines the weak coverage area may not be exactly the same based on different floor plan. In an alternative embodiment, the location identification device may determine that an area farther from the target room is a weak coverage area; alternatively, the location identification device may determine that a room separated from the target room by a plurality of walls is a weak coverage area, which is not limited herein.

Step 307, displaying a first prompt message through the user interface, where the first prompt message is used to prompt the user about the room type of the weak coverage area.

Step 307 is an optional step.

After the location identification device determines the room type of the weak coverage area, the location identification device presents a first prompt message through a user interface, wherein the first prompt message is used for prompting a user about the room type of the weak coverage area. Still taking the aforementioned fig. 4C as an example, if the location identification device determines that the room type of the weak coverage area is "bedroom 2", the location identification device will prompt the user that the signal quality of bedroom 2 is not good, and it is recommended to install an access point in bedroom 2 ".

In this embodiment, the location identification device can determine the type of the room in which the terminal is located and the relative location relationship between the terminal and the access point according to the signal strength value and the throughput rate of the terminal, and determine the type of the room in which the access point is located. And then, determining the room type of the weak coverage area according to the floor plan and the room type of the access point, and prompting a user to optimize the weak coverage area. The method is beneficial to providing network optimization measurement for the user family by the operator and improving the network quality of the user.
