Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is an implementation environment of a wireless network capacity expansion method provided in an embodiment of the present invention, where the implementation environment may include a plurality of network access devices 101 and at least one terminal 102, and referring to fig. 1, it is described that the implementation environment includes a plurality of terminals 102 as an example, the plurality of network access devices 101 may be distributed and deployed, each network access device 101 may have a certain signal coverage, and each network access device 101 may provide a wireless network access service for the terminal 102 within its signal coverage.

In the embodiment of the present invention, the terminal 102 may acquire the network data through the network access device 101 by establishing a network connection with the network access device 101. The network Access device 101 may be a Wireless router, a Wireless Access Point (AP), and other devices that can provide a Wireless network Access service, and of course, the network Access device 101 may also be other devices that can provide a Wireless network Access service, which is not limited in this embodiment of the present invention.

In this embodiment of the present invention, the network access device 101 has a wireless network capacity expansion function, and when a network connection requirement in a signal coverage area of a certain network access device becomes large, the network access device may ask for help from other network access devices, so that the other network access devices can assist the network access device, and the other network access devices and the network access device can provide a wireless network access service for a terminal in the signal coverage area of the network access device together, thereby implementing wireless network capacity expansion and optimizing a network environment.

Fig. 2 is a flowchart of a wireless network capacity expansion method according to an embodiment of the present invention, where in the embodiment of the present invention, a first network access device and a second network access device are a network access device for assisting and a network access device seeking help from the first network access device, that is, a network access device that needs help is referred to as a second network access device, and other network access devices except the second network access device are the first network access device, and when a network access load condition of the second network access device meets a certain condition, the first network access device may be requested to assist. In the following embodiments, only one first network access device interacting with a second network access device is described as an example, and the first network access device assists. Referring to fig. 2, the wireless network extension method may include the steps of:

201. and the second network access equipment acquires the network access load condition of the second network access equipment.

The second network access device may obtain a network access load condition of itself, so as to determine whether the current network access load condition exceeds a maximum load that can be borne by the second network access device, and if the current network access load condition exceeds the maximum load, a wireless network access service that can be obtained by a terminal connected to the second network access device may be unsmooth and may cause network congestion, so after step 201, the second network access device may determine whether the current network access load condition meets a second target condition. If yes, the following step 202 is executed to ensure better wireless network access service; if not, the second network access device may not need to perform step 202 or discard the network access load condition.

The network access load condition of the second network access device may be characterized in various ways, for example, the network access load condition of the second network access device may be characterized by using the number of terminals connected to the second network access device, or the network access load condition of the second network access device may be characterized by using the bandwidth occupation value of the second network access device. This step 201 may be either of the following two cases:

in case one, the second network access device obtains the number of terminals connected to the second network access device.

And in the second situation, the second network access equipment acquires the bandwidth occupation value of the second network access equipment.

In a possible implementation manner, the step 201 may be triggered by the second network access device establishing a connection with the terminal, or may be periodically executed by the second network access device, that is, the step 201 may be executed every preset time duration, and of course, the step 201 may also be triggered by other steps, for example, the step 201 may be executed when the second network access device receives an acquisition instruction sent by other devices, which is not limited in the embodiment of the present invention.

202. And when the network access load condition meets a second target condition, the second network access equipment sends a wireless network capacity expansion help seeking request.

When the network access load condition of the second network access device meets the second target condition, the second network access device determines that the help of other network access devices is needed, so that the wireless network capacity expansion help seeking request can be sent, and the wireless network capacity expansion help seeking request is used for requesting the first network access device to provide wireless network capacity expansion service for the second network access device.

In one possible implementation manner, in step 202, the second network access device may broadcast the wireless network capacity expansion help request, and any first network access device may receive the wireless network capacity expansion help request. In another possible implementation manner, in step 202, the second network access device may first establish a communication connection with the first network access device, and after the establishment is completed, the second network access device sends a wireless network capacity expansion help-seeking request to the first network access device that establishes a communication connection with the second network access device. The embodiment of the present invention does not limit what specific implementation manner is adopted.

In one possible implementation, the network access load condition satisfying the second target condition may be: the number of the terminals connected with the second network access device is larger than a second number threshold or the bandwidth occupation value of the second network access device is larger than a second bandwidth threshold. The second quantity threshold and the second bandwidth threshold may be used to characterize a maximum load that the second network access device can bear. When the current network access load condition of the second network access device exceeds the maximum load, the first network access device needs to ask for help, so that the first network access device moves to the vicinity of the second network access device and shares the network connection requirement for the second network access device. Of course, the first network access device may also provide assistance for the second network access device in other manners, which may specifically refer to step 208 below, and embodiments of the present invention are not described herein in detail.

The second quantity threshold and the second bandwidth threshold may also be set by a related technician according to a requirement, for example, the maximum number of terminals that the second network access device can connect to is 10, the second quantity threshold may be set to be 10, and when the number of terminals that the second network access device connects to is greater than 10, for example, the number of terminals that the first network access device connects to is 11, the second network access device may send a wireless network capacity expansion help-seeking request. For another example, if the second bandwidth threshold is 95%, the bandwidth occupied value of the first network access device is 96%, and is greater than the second bandwidth threshold, the second network access device may send a wireless network capacity expansion help request. The specific values of the second quantity threshold and the second bandwidth threshold are not limited in the embodiment of the present invention.

Of course, the above only provides two expressions of the network access load condition, and the network access load condition may also be characterized by using other parameters, for example, the amount of data transmitted by the second network access device in the target time period, for example, the amount of data transmitted in three minutes, and the embodiment of the present invention is not limited by which parameter the network access load condition is specifically measured.

In step 202, if the network access load condition satisfies the second target condition, it indicates that the second network access device needs the assistance of the first network access device, and therefore, the second network access device may send a wireless network capacity expansion help request.

In a possible implementation manner, the wireless network capacity expansion help-seeking request may carry identification information of the second network access device, where the identification information is used to uniquely identify the second network access device. The first network access device receiving the wireless network capacity expansion help seeking request can determine the second network access device needing help seeking according to the identification information of the second network access device. For example, the identification information may be a service set identifier (ssid) of the second network access device, or may be a basic service set identifier (bsic service set identifier (bsid)). Of course, other identification information may also be used, which is not limited in the embodiment of the present invention.

Of course, the wireless network capacity expansion help request may also include other information, for example, the time when the second network access device sends the wireless network capacity expansion help request, or the altitude of each network access device may be different, the wireless network capacity expansion help-seeking request may further include an altitude of the second network access device, or the wireless network capacity expansion help-seeking request may further include identification information of a neighboring first network access device of the second network access device, the adjacent first network access device may be the first network access device within a preset range around the second network access device, or the first network access devices in the preset number whose signal strength detected by the second network access device is greater than the strength threshold value.

Of course, if the network access load condition does not satisfy the second target condition, which indicates that the second network access device can bear the current load, the first network access device is not required to assist, and thus the second network access device may discard the network access load condition without sending a wireless network capacity expansion help request. In a possible implementation manner, the step shown in step 201 above, in which the second network access device determines whether the network access load condition satisfies the second target condition, may be implemented by a load evaluation module in the second network access device. For example, as shown in fig. 3, in one particular example, the first network access device and the second network access device may each be referred to as a wireless-fidelity (Wi-Fi) device, which may provide Wi-Fi connectivity services. Taking step 201 as an example of connection triggering established between the second network access device and the user terminal, the second network access device may establish connection with the user terminal, and after establishing connection with the user terminal, a load evaluation module of the second network access device may evaluate a network access load condition, specifically, the second network access device may obtain a number of terminals or a bandwidth occupation value connected to itself, determine whether the number of terminals connected exceeds a second number threshold, or determine whether the bandwidth occupation value is greater than a second bandwidth threshold, if so, the second network access device may read device information of itself, generate a wireless network capacity expansion help-seeking request based on the device information, and thereby send the wireless network capacity expansion help-seeking request outwards; if not, the second network access device may not send a wireless network capacity expansion help seeking request to the outside.

203. And the first network access equipment receives a wireless network capacity expansion help seeking request sent by the second network access equipment.

After the second network access device sends a wireless network capacity expansion help seeking request, any first network access device can receive the wireless network capacity expansion help seeking request sent by the second network access device, and after the first network access device receives the wireless network capacity expansion help seeking request sent by the second network access device, the first network access device can judge the self condition to determine whether to assist.

204. The first network access device obtains the network access load condition of the first network access device to evaluate whether the first network access device has the capability of providing the wireless network capacity expansion service for the second network access device.

After receiving the request for help to expand the wireless network, the first network access device may execute step 204 to evaluate whether it has the capability of providing the wireless network expansion service. The wireless network capacity expansion help seeking request is sent by the second network access equipment when the network access load condition meets the second target condition. After the step 204, the first network access device may determine whether a network access load condition of the first network access device satisfies a first target condition, if so, execute the step 205, and if not, the first network access device may determine that the first network access device does not have a capability of providing a wireless network capacity expansion service, and the first network access device may discard the wireless network capacity expansion help request.

In a possible implementation manner, after the step 203, the first network access device may further obtain signal strengths of other first network access devices within the target range of the first network access device, and evaluate the assisting capability of the first network access device by integrating the network access load condition and the signal strength. The first network access device may determine whether the network access load condition satisfies a first target condition, and determine whether the signal strength satisfies a third target condition, if both are yes, the first network access device may send a wireless network capacity expansion help-seeking response to the second network access device, and if either of the two determination results is no, the first network access device may determine that there is no capability to provide a wireless network capacity expansion service, and the first network access device may discard the wireless network capacity expansion help-seeking request.

205. And when the network access load condition of the first network access equipment meets a first target condition, the first network access equipment sends a wireless network capacity expansion help seeking response to the second network access equipment.

The first network access device may determine whether a network access load condition of the first network access device satisfies a first target condition. When the network access load condition of the first network access equipment meets a first target condition, the first network access equipment can determine that the first network access equipment can assist the first network access equipment, so that a wireless network capacity expansion help seeking response can be sent to second network access equipment, and the wireless network capacity expansion help seeking response is used for informing that the first network access equipment can assist the second network access equipment to provide wireless network access service; when the network access load condition of the first network access equipment does not meet the first target condition, the first network access equipment does not need to send wireless network capacity expansion help seeking response. In one possible implementation, the first network access device may discard the received wireless network capacity expansion help request. Of course, the obtained network access load situation may also be discarded.

The first network access device can determine whether the network connection requirement in the signal coverage range of the first network access device is smaller through the network access load condition of the first network access device, so that when the network connection requirement in the signal coverage range is determined to be smaller, the first network access device assists the second network access device, a terminal in the original signal coverage range of the first network access device can be connected with other network access devices, too large load burden on other network access devices can not be caused, and the network connection requirement in the original signal coverage range of the first network access device cannot be met due to the fact that the first network access device assists the second network access device.

Similarly, the network access load condition of the first network access device may be characterized in a variety of ways, for example, the network access load condition of the first network access device may be characterized by the number of terminals connected to the first network access device, or the network access load condition of the first network access device may be characterized by the bandwidth occupancy value of the first network access device. Specifically, the first target condition that the network access load condition of the first network access device satisfies may be any one of the following two conditions.

The first condition is as follows: the number of terminals to which the first network access device is connected is less than a first number threshold.

Case two: the bandwidth occupancy value of the first network access device is less than a first bandwidth threshold.

The first number threshold and the first bandwidth threshold may also be set by a relevant technician according to a requirement, for example, the maximum number of terminals that the first network access device can connect to is 10, the first number threshold may be set to be 8, and when the number of terminals connected to the first network access device is less than 8, the first network access device may send a wireless network capacity expansion help-seeking response. For another example, if the first bandwidth threshold is 80%, the bandwidth occupied value of the first network access device is 70%, and is smaller than the first bandwidth threshold, the first network access device may send a wireless network capacity expansion help-seeking response. The specific values of the first number threshold and the first bandwidth threshold are not limited in the embodiments of the present invention.

Of course, the above only provides two expressions of the network access load condition, and the network access load condition may also be characterized by using other parameters, for example, the amount of data transmitted by the first network access device in the target time period, for example, the amount of data transmitted in three minutes, and the embodiment of the present invention is not limited by which parameter the network access load condition is specifically measured.

In a possible implementation manner, in this step 204, the first network access device may further obtain other information, so as to evaluate whether it is capable of providing the wireless network capacity expansion service for the second network access device based on the other information. For example, the first network access device may further obtain signal strengths of other first network access devices within the target range of the first network access device, so as to evaluate whether it is capable of providing the wireless network capacity expansion service for the second network access device based on the signal strengths and the network load condition.

The first network access device can determine whether other first network access devices exist near the first network access device through the signal strength of other first network access devices around the first network access device, so that after the first network access device assists the second network access device, other first network access devices in the original signal coverage area of the first network access device can provide wireless network access service for the terminal in the signal coverage area.

Specifically, the first network access device may determine whether the network access load condition satisfies a first target condition and determine whether the signal strength satisfies a third target condition, and when the network access load condition of the first network access device satisfies the first target condition and the signal strength satisfies the third target condition, the first network access device sends a wireless network capacity expansion help-seeking response.

the number of terminals connected by the first network access device is less than a first number threshold;

the bandwidth occupancy value of the first network access device is less than a first bandwidth threshold.

The signal strength meeting the third target condition may be the signal strength being greater than a signal strength threshold.

The first target condition and the third target condition may be preset by a technician, and the signal strength threshold may be set by the technician according to a requirement, for example, the signal strength threshold may be-90 decibel milliwatts (dBm), and when the first network access device detects that the signal strength of other first network access devices within the target range is greater than-90 dBm, the first network access device may send a wireless network capacity expansion help-seeking response. The embodiment of the present invention does not limit the specific value of the signal strength threshold.

The embodiment of the present invention is not limited thereto. Therefore, whether the first network access equipment has the capacity expansion service of the wireless network can be more accurately evaluated by judging the two conditions.

Certainly, only two evaluation manners are provided, and the first network access device may also perform evaluation in other manners, for example, in step 204, the first network access device may further only obtain signal strengths of other first network access devices within the target range of the first network access device, then determine whether the signal strengths meet a third target condition, and when the signal strengths meet the third target condition, the first network access device sends a wireless network capacity expansion help-seeking response to the second network access device.

Of course, the evaluation process may also be evaluated through other information, for example, the distance between the first network access device and the second network access device is smaller than a threshold, and the wireless network capacity expansion help request may carry location information of the second network access device, so that the first network access device determines whether the distance is smaller than the threshold according to the location information and the location information of the first network access device, and for example, the first network access device may determine whether the signal strength of the second network access device is detected to be greater than a strength threshold, and the evaluation manner of the assistance capability of the first network access device in step 204 and step 205 is not limited in the embodiment of the present invention.

For example, as shown in fig. 4, in step 204 and step 205, the first network access device may receive a wireless network capacity expansion help-seeking request, and the first network access device may determine, according to device information of the second network access device included in the wireless network capacity expansion help-seeking request, that the wireless network capacity expansion help-seeking request is a wireless network capacity expansion help-seeking request sent by the second network access device, and obtain a network condition of itself, determine whether itself has an assistance condition, take as an example whether the first network access device has the assistance condition by specifically adopting a method of determining, by using a signal strength of a network access load condition, that the first network access device may obtain a network access load condition of itself and signal strengths of other first network access devices within a target range, where the network access load condition may be a number of connected terminals or a bandwidth occupation value, the first network access equipment can judge whether the number of the terminals is larger than a second number threshold or whether the bandwidth occupation value is larger than a second bandwidth threshold, the terminals can also judge whether the signal intensity of other first network access equipment in a target range is larger than a signal intensity threshold, if the judgment results of the first network access equipment and the second network access equipment are both yes, the first network access equipment can determine that the first network access equipment has the assistance condition, so that the equipment information of the first network access equipment can be read, a wireless network capacity expansion help-seeking response is generated based on the equipment information, the wireless network capacity expansion help-seeking response is sent outwards, and if at least one of the judgment results of the first network access equipment and the second network access equipment is not judged to have the assistance condition, so that the wireless network capacity expansion help-seeking response is not sent outwards. In fig. 4, only the case three is taken as an example for explanation, if the above-mentioned case one or case two is adopted, the first network access device only needs to obtain the network access load condition of itself or the signal strength of other first network access devices within the target range, so as to perform a one-step judgment, and then it can be determined whether to send a wireless network capacity expansion help-seeking response, which is not described herein again in this embodiment of the present invention.

In a possible implementation manner, the wireless network capacity expansion help-seeking response may carry identification information of the first network access device, where the identification information is used to uniquely identify the first network access device. Certainly, the wireless network capacity expansion help-seeking response may also carry identification information of the second network access device, and is used to indicate that the help-seeking response is a help-seeking response fed back by the wireless network capacity expansion help-seeking request based on the second network access device. The identification information may also be an ssid and/or a bssid, for example. Of course, other identification information may also be used, which is not limited in the embodiment of the present invention.

Certainly, the wireless network capacity expansion help-seeking response may further include other information, for example, the time when the first network access device sends the wireless network capacity expansion help-seeking response, the time when the second network access device sends the wireless network capacity expansion help-seeking request, the time when the first network access device receives the wireless network capacity expansion help-seeking request, or the altitude of the first network access device, or the wireless network capacity expansion help-seeking response may further include the signal strength of the second network access device detected by the first network access device, the number of terminals connected to the first network access device may also be included in the wireless network capacity expansion help-seeking response, and the content included in the wireless network capacity expansion help-seeking response is not limited in the embodiment of the present invention.

206. And the second network access equipment receives the wireless network capacity expansion help seeking response sent by the first network access equipment.

The second network access device receives the wireless network capacity expansion help seeking response of the first network access device, and therefore the fact that the first network access device can assist the first network access device in providing the wireless network access service can be obtained.

In a possible implementation manner, in step 202, after the second network access device sends the wireless network capacity expansion help-seeking request, each first network access device may determine whether it meets the assistance requirement after receiving the wireless network capacity expansion help-seeking request, so that when it is determined that the requirement is met, a wireless network capacity expansion help-seeking response is sent to the second network access device, and thus, in step 206, the second network access device may receive the help-seeking response of one first network access device, and may also receive the wireless network capacity expansion help-seeking responses of a plurality of first network access devices, that is, the second network access device receives the wireless network capacity expansion help-seeking response of at least one first network access device.

Accordingly, after step 206, the second network access device may further perform the following steps one and two:

step one, the second network access device obtains the target first network access device according to the wireless network capacity expansion help seeking response of the at least one first network access device.

In step 206, the second network access device may further screen the received wireless network capacity expansion help-seeking response of the at least one first network access device, and in order to ensure that the second network access device can be assisted quickly during the screening, a received preset time period and/or a first target number may be set to select the received wireless network capacity expansion help-seeking response of the at least one first network access device. Specifically, the following three cases may be included in such an arrangement:

in the first case, the second network access device obtains the target first network access device according to the wireless network capacity expansion help seeking response of at least one first network access device received in the preset time period.

In this case, the preset time period may be a time period after the second network access device sends the wireless network capacity expansion help request, for example, the duration of the preset time period may be 2 minutes, so that the second network access device receives wireless network capacity expansion help responses of some first network access devices within 2 minutes after sending the wireless network capacity expansion help request, and after 2 minutes, the second network access device receives wireless network capacity expansion help responses of other first network access devices, and may discard the responses, or does not discard the responses, but does not consider the other first network access devices when obtaining the target first network access device. The duration of the preset time period may be set by a relevant technician according to a requirement, which is not limited in the embodiment of the present invention.

And in the second situation, the second network access equipment acquires the target first network access equipment according to the wireless network capacity expansion help seeking response of the first network access equipment with the first target quantity before the receiving time.

In this case two, the first target number may be set by a related technician according to requirements, which is not limited by the embodiment of the present invention. For example, the first target number may be 4, so that the second network access device receives the wireless network capacity expansion help seeking response of the first network access device after sending the wireless network capacity expansion help seeking request, when receiving 4 wireless network capacity expansion help seeking responses, the second network access device may obtain the target first network access device from the 4 first network access devices, and after receiving the wireless network capacity expansion help seeking response of another first network access device, the second network access device may discard the target first network access device, or may not discard the target first network access device but does not consider the another first network access device when obtaining the target first network access device.

And thirdly, the second network access equipment receives the wireless network capacity expansion help-seeking responses of the first network access equipment with the first target quantity before the time according to the wireless network capacity expansion help-seeking response of at least one first network access equipment received in the preset time period, and acquires the target first network access equipment.

In this case three, the second network access device may consider both the preset time period and the target number, and may receive a wireless network capacity expansion help-seeking response of the first network access devices exceeding the first target number in the preset time period, so that the second network access device may select the target first network access device from the plurality of first network access devices.

In a possible implementation manner, in the process of acquiring the target first network access device, the second network access device may further acquire one or more target first network access devices according to the received help-seeking response. Of course, the number of wireless network capacity expansion help-seeking responses received by the second network access device is different, and the number of the first network access devices that the second network access device can select as a target may also be different. Specifically, the following three cases may be included:

in the first case, when receiving a wireless network capacity expansion help-seeking response of a first network access device, a second network access device takes the first network access device as the target first network access device. In this case, in the first case, the second network access device receives only one wireless network capacity expansion help seeking response of the first network access device, and may use the first network access device as the target first network access device.

And in the second situation, when receiving wireless network capacity expansion help seeking responses of the plurality of first network access devices, the second network access device acquires the assistance scores of the plurality of first network access devices, and acquires a second target number of first network access devices from the plurality of first network access devices as the target first network access devices according to the assistance scores of the plurality of first network access devices.

And thirdly, when receiving wireless network capacity expansion help-seeking responses of a plurality of first network access devices, the second network access device randomly selects a second target number of first network access devices from the plurality of first network access devices as the target first network access devices.

In the second and third cases, the second network access device receives wireless network capacity expansion help seeking responses of the plurality of first network access devices, and then a second target number of first network access devices may be selected from the plurality of first network access devices. The second target number may be set by a related technician as required, for example, the second target number may be 1, and of course, the second target number may also be set to other values, which is not limited in the embodiment of the present invention.

In this case two, the obtaining process of the assistance scores of the plurality of first network access devices may be implemented by the following steps 1 to 5, and in a possible implementation manner, the second network access device may perform the following steps 1 to 5, or may perform at least one of the following steps 1 to 4, so as to perform step 5, specifically, the steps 1 to 5 may be as follows:

step 1, for each first network access device, the second network access device obtains the time difference fraction of the first network access device based on the time of sending and receiving signals of the first network access device and the second network access device.

In step 1, if the first network access device and the second network access device are closer to each other and the communication is smooth, the time difference obtained based on the time for transmitting and receiving the signal between the first network access device and the second network access device is smaller, so that the time difference can be used as a measurement factor in the assistance score of the first network access device, and the time difference score can represent whether the time difference between the first network access device and the second network access device for transmitting the signal is large or small, and can represent the assistance capability of the second network access device reflected by the large or small time difference, or represent whether to facilitate assistance to the second network access device, or represent whether to rapidly and efficiently assist the second network access device.

Specifically, in step 1, the second network access device may obtain a time difference between signals sent and received by the first network access device and the second network access device based on the first time, the second time, the third time, and the fourth time; and the second network access equipment acquires the time difference fraction of the first network access equipment based on the time difference. The first time is the time when the second network access device sends the wireless network capacity expansion help seeking request, the second time is the time when the first network access device receives the wireless network capacity expansion help seeking request, the third time is the time when the first network access device sends the wireless network capacity expansion help seeking response, and the fourth time is the time when the second network access device receives the wireless network capacity expansion help seeking response.

In one possible implementation, the time difference fraction may be inversely related to the time difference. The larger the time difference is, the smaller the time difference is; the smaller the time difference, the larger the time difference number.

In a possible implementation manner, the second network access device may obtain a first difference between the second time and the first time, obtain a second difference between the fourth time and the third time, and obtain an average value of the first difference and the second difference as a time difference between signals transmitted and received by the first network access device and the second network access device. For example, the time difference obtaining process can be implemented by using the following formula:

[(Tah-Tsh)+(Tar-Tsr)]*0.5＝Te

tah denotes a time when the first network access device receives the wireless network capacity expansion help-seeking request, Tsh denotes a time when the second network access device sends the wireless network capacity expansion help-seeking request, Tar denotes a time when the second network access device receives the wireless network capacity expansion help-seeking response, Tsr denotes a time when the first network access device sends the wireless network capacity expansion help-seeking response signal, and Te denotes a calculated signal transmission time difference, that is, a time difference between sending and receiving of signals by the first network access device and the second network access device, where the unit may be millisecond, certainly, second, and the like, and this is not limited in the embodiments of the present invention.

In a specific possible embodiment, the second network access device may further convert the time difference into time difference indication information within a preset range, and the time difference indication information is positively correlated with the time difference. For example, the time difference may be normalized, so that the time difference of each first network access device is in the same range, which may facilitate subsequent calculation and improve calculation efficiency. For example, the process may be implemented using the following equation:

Te/(Temax-Temin+1)＝Teuni

wherein Te is a calculated signal transmission time difference, that is, a time difference between signals transmitted and received by the first network access device and the second network access device (both may be Wi-Fi devices), Temax is a set maximum time difference between signals transmitted and received by both Wi-Fi devices, and may be, for example, 2 minutes, and if a unit is millisecond, Temax is 2 × 60 × 1000 is 120000 milliseconds, Temin is a set minimum time difference between signals transmitted and received by both Wi-Fi devices, and may be, for example, 0 millisecond; if Te is greater than Temax, setting Te as Temax, wherein Te is Temax; teuni is time difference indication information obtained after normalization, so the value range of Teuni is [0,1], that is, 0< ═ Teuni < ═ 1, in this example, a wireless network capacity expansion help request and a wireless network capacity expansion help response are sent by way of signals.

Further, the second network access device may obtain the time difference score of the first network access device based on the time difference or based on the time difference indication information, and of course, after obtaining the time difference score, the second network access device may also perform normalization processing on the time difference score to facilitate subsequent calculation. Specifically, the process may be implemented by the following formula:

1/Teuni＝(Temax-Temin+1)/(Te+1)＝Tscore

wherein Te is a calculated signal transmission time difference, that is, a time difference between signals transmitted and received by the first network access device and the second network access device (both may be Wi-Fi devices), Temax is a set maximum time difference between signals transmitted and received by both Wi-Fi devices, Temin is a set minimum time difference between signals transmitted and received by both Wi-Fi devices, tenui is time difference indication information obtained after normalization, and Tscore is a time difference fraction obtained based on the time difference indication information without normalization. Since Temin < ═ Te < ═ Temax, to prevent the denominator from being 0, in the above formula, Te is added by 1, since 1 is small, the calculated score is not affected, and Tscore becomes small as the time difference Te becomes large.

Further, the time difference fraction may be normalized by the following formula:

Tscore/(Tscore_max-Tscore_min)＝Tus

wherein, Tscore is a time difference fraction which is obtained based on the time difference indication information and is not normalized, Tscore _ max is a maximum time difference fraction, Tscore _ max is (Temax-0+1)/(0+1) Temax +1, Tscore _ min is a minimum time difference fraction, Tscore _ min is Temax/(Temax +1), and Temax is a set maximum time difference value of signals transmitted and received by both Wi-Fi devices.

Wherein Tscore _ max-Tscore _ min

＝(Temax+1)-Temax/(Temax+1)

＝Temax+1/(Temax+1)。

Then, Tus is Tscore/[ Temax +1/(Temax +1) ], and the value range of Tus is: 0< ═ Tus < 1.

The above description provides only an exemplary illustration, and the values of the parameters set in the above example can be set or adjusted by a person skilled in the relevant art according to requirements, which is not limited by the embodiment of the present invention. Of course, the second network access device may also calculate the time difference score in other manners, for example, the time difference may be directly used as the time difference score, or normalization processing may not be required, which is not limited in this embodiment of the present invention.

And 2, the second network access equipment acquires the height difference fraction of the first network access equipment based on the heights of the first network access equipment and the second network access equipment.

In this step 2, if the first network access device and the second network access device are deployed at different heights, the height difference between the first network access device and the second network access device may also characterize the distance between the first network access device and the second network access device to some extent. Therefore, the height difference between the first network access device and the second network access device can be used as a measuring factor for measuring the assistance score of the first network access device, the height difference score can represent the height of the first network access device and the height of the second network access device, the assistance capability of the second network access device reflected by the height difference or the height of the second network access device can be represented, whether the second network access device is conveniently assisted or not can be represented, and whether the second network access device can be assisted quickly and efficiently can be represented.

In one possible approach, in step 2, the second network access device may obtain a height difference between the first network access device and the second network access device based on the heights of the first network access device and the second network access device, so as to obtain a height difference score of the first network access device based on the height difference. It will be appreciated that the greater the distance between the two, the more inconvenient the first network access device is to assist the second network access device and, thus, the height difference number may be inversely related to the height. The larger the height is, the smaller the height difference number is; the smaller the height, the larger the height difference number.

For example, the height difference obtaining process may be implemented by the following formula:

|Ah-Ar|＝Ae

wherein, Ah is the altitude of the Wi-Fi device (second network access device) which needs to be helped, Ar is the altitude of the Wi-Fi device (first network access device) which responds to the help seeking Wi-Fi device (second network access device), and Ae is the absolute value of the altitude difference between the two Wi-Fi devices.

In a specific possible embodiment, similarly, the second network access device may also perform normalization processing on the height difference to obtain height difference indication information, where the height difference indication information is positively correlated with the height difference. This can be achieved, for example, by the following formula:

Ae/(Aemax-Aemin)＝Aeuni

wherein Ae is an absolute value of a height difference between two Wi-Fi devices in altitude, Aemax is a set maximum height difference value, such as 100 meters, Aemin is a set minimum height difference value, such as 1 meter, and when Ae is greater than Aemax, Ae is Aemax; when Ae is less than Aemin, Ae ═ Aemin. Aeuni is height difference indication information, and the value range of the Aeuni is as follows: Aemin/(Aemax-Aemin) < ═ Aeuni < (1); taking Aemax as 100 and Aemin as 1 as an example, the value range of Aeuni is: 1/99< (Aeuni < (1); aeuni is proportional to Ae.

Further, the second network access device may obtain the height difference score of the first network access device based on the height difference or based on the height difference indication information, and of course, after the second network access device obtains the height difference score, it may also perform normalization processing on the height difference score to facilitate subsequent calculation. Specifically, the process may be implemented by the following formula:

log(a)(Aeuni)＝Ascore

wherein, a is the base of logarithm, and the value range is as follows: 0< a <1, Aeuni is height difference indicating information, and Ascore is a height difference fraction which is not subjected to normalization processing. Since Aeuni also ranges between 0 and 1, Ascore decreases with increasing Aeuni, and thus, as shown in FIG. 5, Ascore is negatively correlated with Aeuni when 0< a < 1. In one example, if values are set for Aeuni and a, a range of values for Ascore can be obtained, for example, when 1/99< ═ Aeuni < > 1 and a ═ 0.5, 0< ═ Ascore < 6.7.

Further, the height difference number may be normalized by the following formula:

Ascore/(Ascore_max-Ascore_min)＝Aus

the maximum score obtained by Ascore is obtained when Aeuni takes the minimum value Aemin, where Ascore _ max may be represented by Ascore _ max, and when Ascore _ max is log (a) (Aemin/(Aemax-Aemin)), such as Aeuni, 1/99, Ascore _ max is equal to about 6.64. Ascore obtains a minimum score when Aeuni takes the maximum value Aeuni ═ Aemax, where Ascore _ min may be used to represent the minimum score. The minimum score may be calculated as follows:

log(a)(Aeuni/(Aemax-Aemin))＝log(a)(Aemax/(Aemax-Aemin))

because Aemax > > Aemin, log (a) (Aemax/(Aemax-Aemin)) may be approximately equal to log (a) (Aemax/Aemax), and thus the more equal value may be log (a) (1), i.e., 0. Then, Ascore _ min is 0.

It can be found by analysis that when the Ascore obtains the maximum, the Aus maximum value Aus _ max can be calculated according to the formula:

Aus_max＝Ascore_max/(Ascore_max-Ascore_min)

＝Ascore_max/Ascore_max

＝1

when the Ascore obtains the minimum component, calculating the Aus minimum Aus _ min according to a formula, namely:

Aus_min＝Ascore_min/(Ascore_max-Ascore_min)

＝0/(Ascore_max-0)

＝0

therefore, when the height difference is larger, the normalized height difference fraction Aus is smaller, and the value is between 0 and 1, namely Aemin < (Ae) > (Aemax), and 0< (Aus) < ═ 1.

The above description provides only an exemplary illustration, and the values of the parameters set in the above example can be set or adjusted by a person skilled in the relevant art according to requirements, which is not limited by the embodiment of the present invention. Of course, the second network access device may also calculate the height difference score in other manners, for example, the height difference may be directly used as the height difference score, or normalization processing may not be required, which is not limited in this embodiment of the present invention.

And 3, the second network access equipment acquires the signal intensity score of the first network access equipment based on the signal intensity of the second network access equipment detected by the first network access equipment and the signal intensity of the first network access equipment detected by the second network access equipment.

In step 3, if the first network access device and the second network access device are closer to each other and the communication is smooth, the signal strength of the two devices detected by each other is greater, so that the signal strength of the two devices can be used as a factor for measuring the assisting score of the first network access device, and the signal strength score can reflect whether the signal strength detected by the first network access device and the second network access device is strong or weak, can reflect the assisting capability of the second network access device reflected by the strong or weak signal strength, or can reflect whether to facilitate assisting the second network access device, or can reflect whether to assist the second network access device quickly and efficiently. It is understood that the signal strength score is positively correlated to the signal strength of the two when they detect each other. That is, the greater the signal strength score.

In one possible implementation manner, the second network access device may obtain an average signal strength of the second network access device detected by the first network access device and the signal strength of the first network access device detected by the second network access device, and obtain the signal strength score of the first network access device based on the average signal strength. The signal strength score is positively correlated with the average signal strength, and the greater the average signal strength, the greater the signal strength score.

For example, the average signal strength can be obtained by the following formula:

(|dBah|+|dBar|)*0.5＝dB

the first network access device (first network access device) is used for assisting the Wi-Fi device (first network access device) to receive a wireless network capacity expansion help seeking request of the Wi-Fi device (second network access device) needing help seeking, the second network access device (second network access device) is used for assisting the Wi-Fi device (first network access device) to receive a wireless network capacity expansion help seeking response of the Wi-Fi device (second network access device), and the dB is the average signal intensity.

Further, the process of the second network access device obtaining the signal strength score of the first network access device based on the average signal strength may be implemented by the following formula:

|dB-dBmin|/|dBmax-dBmin|＝dBscore

when both dBah and dBar are greater than the set signal intensity threshold dBT, the maximum value dBmax of the average signal intensity can be obtained. That is, dBah ═ dBT |, dBar ═ dBT |, and thus dBmax ═ dBT |. When both dBah and dBar are less than the set signal strength threshold dBL, the minimum value of the average signal strength dBmin can be obtained. dBah ═ dBL |, dBar |, dBL |, and then dBmin |, dBL |. Where dBscore is the signal strength fraction and is proportional to dB. When dB is greater than dBmax, dB ═ dBmax, the signal strength score maximum value dBscore _ max can be found:

dBscore_max＝|dB-dBmin|/|dBmax-dBmin|

＝|dBT-dBL|/|dBT-dBL|

＝1

when dB is less than dBmin, dB ═ dBmin, the signal strength fraction minimum value dBscore _ min can be obtained:

dBscore_min＝|dB-dBmin|/|dBmax-dBmin|

＝|dBL-dBL|/|dBT-dBL|

＝0

thus, the value of dBscore is: 0< ═ dBscore < > 1, no renormalization is required.

The above description provides only an exemplary illustration, and the values of the parameters set in the above example can be set or adjusted by a person skilled in the relevant art according to requirements, which is not limited by the embodiment of the present invention. In addition, the above description is only given by taking as an example a process in which the second network access device calculates the average signal strength first and then obtains the signal strength score based on the average signal strength, and the second network access device may also calculate the signal strength score in other manners, for example, the sum of the signal strengths of the second network access device and the second network access device may be directly used as the time difference score, which is not limited in the embodiment of the present invention.

And 4, the second network access equipment acquires the load score of the first network access equipment based on the network access load condition of the first network access equipment.

In the step 4, when the second network access device considers the assisting score of the first network access device, it can be understood that when the network access load condition of the first network access device is better, and the first network access device assists the second network access device to provide the wireless network access service, the network connection condition in the original signal coverage of the first network access device is not greatly affected. Thus, the network access load condition of the first network access device may be used as one of the metrics of the assistance score. The load score may represent whether the network access load condition of the first network access device is good or bad, may represent the assistance capability of the second network access device reflected by the good or bad network access load condition, or may represent whether to facilitate assistance of the second network access device, or may represent whether to rapidly and efficiently assist the second network access device.

The network access load condition may be a network access load condition of the first network access device that can be characterized by using the number of terminals connected to the first network access device, or a network access load condition of the first network access device that can be characterized by using a bandwidth occupancy value of the first network access device. The second network access device may obtain the load score of the first network access device based on the number of terminals connected to the first network access device and/or the bandwidth occupation value of the first network access device. It will be appreciated that the load score is inversely related to the number of terminals to which the first network access device is connected and the load score is inversely related to the bandwidth usage value of the first network access device.

The following provides but one specific example in which the second network access device obtains the load score of the first network access device based on the number of terminals to which the first network access device is connected. Specifically, the process may normalize the number of terminals connected by the first network access device by the following equation:

Ln/(Lnmax-Lnmin)＝Lnuni

where, Lnmax is a set maximum connection number of the Wi-Fi devices (first network access devices), Lnmin is a set minimum connection number of the Wi-Fi devices (first network access devices), such as 0, and Ln is the number of terminals actually connected to the Wi-Fi devices (first network access devices). And the Lnuni is the network access load condition after the normalization processing. Further, for the normalization of the calculation, Ln is set to Lnmax if Ln is greater than Lnmax.

The second network access device may obtain the load score based on the number of terminals connected to the first network access device or based on the number after the normalization processing, and the following description is given by taking the obtaining of the load score based on the number after the normalization processing as an example, and is specifically implemented by using the following formula:

1/(Lnuni+1)＝Lnscore

wherein, Lnuni is the network access load condition after normalization processing, and Lnscore is the load fraction without normalization processing. As Ln becomes larger, the load fraction Lnscore becomes smaller. That is, the larger the number of connected terminals, the smaller the load fraction. By simply converting the above formula, we can get:

Lnscore＝(Lnmax-Lnmin)/(Ln+Lnmax-Lnmin)

further, the load score obtained by the above formula may be normalized:

Lnscore/(Lnscore_max-Lnscore_min)＝Lus

wherein, if and only if Ln is 0, the maximum value of the load fraction Lnscore _ max can be obtained, where Lnscore _ max is 1; a minimum value Lnscore _ min of the load fraction can be found if and only if Ln is Lnmax, where Lnscore _ min is 0.5. Lus is the normalized load fraction, and thus, Lus varies over the range: 0.5< ═ Lus < ═ 1. The larger Ln, the lower the fraction of Lus.

The above description provides only an exemplary illustration, and the values of the parameters set in the above example can be set or adjusted by a person skilled in the relevant art according to requirements, which is not limited by the embodiment of the present invention. Of course, the second network access device may also calculate the load score in other manners, for example, the number of terminals connected to the first network access device may be directly used as the load score, and certainly, normalization processing may not be required, which is not limited in this embodiment of the present invention.

And step 5, the second network access equipment acquires the assistance score of the first network access equipment based on at least one of the time difference score, the altitude difference score, the signal strength score and the load score.

The above steps 1 to 4 provide four measurement factors of the assistance score, and the second network access device may obtain the assistance score of the first network access device by using the at least one measurement factor when obtaining the assistance score, that is, the second network access device may perform the above steps 1 to 4 and then perform the step 5, or may perform at least one of the above steps 1 to 4, thereby performing the step 5, and how to specifically select the setting that can be performed by the relevant technician is not limited in the embodiment of the present invention.

If only one metric is used, the second network access device may use the score of the metric as the assistance score, for example, the second network access device may not consider the altitude difference score, the signal strength score and the load score, and thus perform step 1 and directly use the time difference score as the assistance score in step 5.

If multiple measurement factors are adopted, the second network access equipment can perform weighted summation on the scores of the multiple measurement factors to obtain the assistance score. Taking the second network access device comprehensively considering the above four measurement factors as an example, the process of obtaining the assistance score in step 5 may be implemented by the following formula:

Tus*w1+Aus*w2+Lus*w3+dBscore*w4＝score

where score is an assistance score of the first network access device, w1+ w2+ w3+ w4 is 1, and w1, w2, w3 and w4 are weights of the time difference score, the height difference score, the load score and the signal strength score, respectively, and the weights may be set by a related technician as needed, which is not limited in the embodiment of the present invention. Tus is normalized time difference fraction, 0< ═ Tus < 1; aus is a height difference normalized fraction, and 0< ═ Aus < > 1; lus is the normalized fraction of the connection number, 0.5< ═ Lus < ═ 1; dBscore is the signal strength fraction, 0< ═ dBscore < ═ 1. The range in which the help-seeking Wi-Fi device (second network access device) calculates the assistance score for each responding Wi-Fi device (first network access device) is: 0< ═ score < ═ 1.

The above description provides only an exemplary illustration, and the values of the parameters set in the above example can be set or adjusted by a person skilled in the relevant art according to requirements, which is not limited by the embodiment of the present invention.

Through the above steps 1 to 5, after the second network access device obtains the assistance scores of the respective first network access devices, the target number of first network access devices with the largest assistance scores may be selected as the target first network access devices, so as to execute the following step two.

Step two, the second network access device sends assistance invitation information to the target first network access device, wherein the assistance invitation information is used for indicating the target first network access device to provide wireless network capacity expansion service for the second network access device.

After determining the target first network access device, the second network access device may send assistance invitation information to the target first network access device, the target first network access device may receive the assistance invitation information, and when receiving the assistance invitation information of the second network access device, the target first network access device may perform the following steps 207 and 208 based on the assistance invitation information, so as to provide a wireless network capacity expansion service for the second network access device. For the first network access device that does not receive the assistance invitation information, the following steps 207 and 208 may not be required to be performed.

For example, as shown in fig. 6, when the second network access device receives the wireless network capacity expansion help-seeking response, it may determine whether the wireless network capacity expansion help-seeking response meets a condition for receiving the wireless network capacity expansion help-seeking response, that is, it determines whether the wireless network capacity expansion help-seeking response is received within a preset time period, or whether the wireless network capacity expansion help-seeking response is received within a first target number before the reception time, or whether the wireless network capacity expansion help-seeking response is received within a preset time period and is received within a first target number before the reception time. If the wireless network capacity expansion help-seeking response meets the condition of receiving the wireless network capacity expansion help-seeking response, the first network access equipment corresponding to the wireless network capacity expansion help-seeking response can be used as candidate first network access equipment, and if not, the second network access equipment can discard the wireless network capacity expansion help-seeking response. After determining to end the candidate first network access devices, the second network access device may further determine whether the number of received wireless network capacity expansion help-seeking responses is greater than 1, that is, whether the number of the candidate first network access devices is greater than 1, and if so, the second network access device may select a target first network access device from the plurality of first network access devices randomly or according to an assistance score, where the target first network access device may be an optimal network access device among the plurality of first network access devices, and the second network access device may send assistance invitation information to the target first network access device; if the number is not greater than 1, that is, the number is equal to 1, the second network access device may directly send the assistance invitation information to the first network access device.

It should be noted that, when the second network access device obtains the wireless network capacity expansion help seeking response, it may further determine whether the identification information of the second network access device included in the wireless network capacity expansion help seeking response is consistent with the identification information of the second network access device, if so, it indicates that the wireless network capacity expansion help seeking response is information for responding to the second network access device, and if not, it indicates that the wireless network capacity expansion help seeking response is information for responding to other second network access devices, and the second network access device may also discard the wireless network capacity expansion help seeking response.

207. The first network access device obtains the location information of the second network access device.

After sending the wireless network capacity expansion help seeking response, the first network access device may provide assistance for the second network access device to share the network connection requirement of the terminal within the signal coverage range of the second network access device, that is, the first network access device may provide the wireless network access service for the terminal within the signal coverage range of the second network access device, so that the first network access device and the second network access device together provide the wireless network access service for the terminal within the signal coverage range, and the number of the network access devices connectable to the terminal within the signal coverage range is increased, thereby realizing the capacity expansion of the wireless network, and being capable of solving the situation of network connection requirement increase or network congestion.

The first network access device may first obtain the location information of the second network access device, so as to determine how to move according to the location information, and then the above effects can be achieved. Specifically, the location information of the second network access device may include multiple obtaining manners, and the following are three possible implementation manners, and the first network access device may obtain the location information of the second network access device in any manner.

In the first mode, the wireless network capacity expansion help seeking request carries the position information of the second network access device. The first network access device may extract the location information of the second network access device from the wireless network capacity expansion help request.

In the second mode, the second network access equipment acquires the position information of the second network access equipment based on a global positioning system; and the second network access equipment sends the position information of the second network access equipment to the first network access equipment. And the first network access equipment receives the position information sent by the second network access equipment.

In this second mode, after the step 206, after receiving the wireless network capacity expansion help seeking response, the second network access device may obtain its own location information, and send the location information to the first network access device.

And in the third mode, the first network access equipment sends positioning signals to a plurality of directions, and the positioning signal in each direction carries direction indication information corresponding to the direction. The second network access device receives the positioning signal of the first network access device, and may send a response signal, where the response signal is the same as the direction indication information carried by the positioning signal. And the first network access equipment receives the response signal sent by the second network access equipment and extracts the direction indication information carried by the response signal.

In the third mode, the first network access device may determine the location information of the second network access device according to the direction indication information carried in the response signal returned by the second network access device by sending the positioning signal carrying multiple kinds of direction indication information. Specifically, the positioning signal and the response signal may be a sound wave, an electromagnetic wave, or other types of waves, which is not limited in the embodiment of the present invention.

It should be noted that, in the third mode, the first network access device may further send a positioning signal to each direction, where the positioning signal in each direction carries direction indication information corresponding to the direction, and when the second network access device returns a response signal carrying the direction indication information corresponding to the direction, the first network access device may narrow a range of the direction in which the positioning signal is sent, and send the positioning signal again, and so on, so that the first network access device and the second network access device may maintain communication, and constantly determine directions of each other, and the first network access device gradually approaches to the direction in which the second network access device is located in the moving process.

208. The first network access equipment generates a moving path according to the position information of the second network access equipment, and drives the first network access equipment to move towards the second network access equipment until the first network access equipment enters a corresponding position range capable of providing wireless network access service for the terminal in the signal coverage range of the second network access equipment.

The first network access equipment moves to a position range corresponding to the second network access equipment, the signal coverage ranges of the first network access equipment and the second network access equipment in the position range can have a superposition area, and thus a terminal in the superposition area can select any equipment from the first network access equipment and the second network access equipment to connect, so that the first network access equipment shares part of the network connection requirements of the terminal for the second network access equipment, the capacity expansion of a wireless network is realized, the network environment around the network access equipment is optimized, and the problems of network access equipment overload and network blockage can be solved.

Specifically, after the first network access device acquires the location information of the second network access device, the following steps one to two may be performed to implement the moving process in step 208:

step one, the first network access device generates a moving path according to the position information of the first network access device and the position information of the second network access device.

After the first network access device acquires the location information of the second network access device, a moving path may be generated according to the location information of the second network access device and the location information of the first network access device, so as to be close to the second network access device, thereby facilitating assistance for the second network access device, that is, the moving path may enable the first network access device to move toward the location of the second network access device.

In one possible implementation, there may be other objects between the first network access device and the second network access device, such as buildings, other network access devices, and so on, with which the first network access device may collide when moving towards the location of the second network access device. Therefore, in the first step, the first network access device may obtain a scene map where the first network access device and the second network access device are located, and take an object in a target area between the first network access device and the second network access device as an obstacle according to the location information of the first network access device, the location information of the second network access device, and the scene map, and the first network access device may generate a moving path according to the location information of the first network access device, the location information of the second network access device, and the obstacle.

The scene map may be maintained by a server, and the first network access device may obtain the scene map where the first network access device and the second network access device are located from the server. The scene map may include geographic locations of various objects, the objects may also include other network access devices, and of course, the scene map may also include feasible areas and the like. For the location information of the other network access device, the other network access device may synchronize its own location to the server, or may be obtained by positioning the other network access device by the other positioning device, which is not limited in the embodiment of the present invention.

In one possible embodiment, when the first network access device generates the movement path according to the position information of the first network access device, the position information of the second network access device and the obstacle, the first network access device may acquire a plurality of alternative paths, acquire a cost value of each alternative path, and select one alternative path from the plurality of alternative paths as the movement path according to the cost value of each alternative path. The cost value of the alternative path may be implemented according to an algorithm, and details of the embodiment of the present invention are not described herein.

And secondly, the first network access equipment drives the first network access equipment to move along the moving path until the signal intensity of the second network access equipment is detected to be greater than a signal intensity threshold value, the time difference between the signals sent and received by the first network access equipment and the second network access equipment is detected to be smaller than a time threshold value, the distance between the first network access equipment and the second network access equipment is smaller than a distance threshold value, or the identification information of the second network access equipment is collected and the second network access equipment is successfully identified, and then the first network access equipment stops moving.

After the first network access device generates the moving path, the first network access device may drive itself to move along the moving path, and when moving along the moving path, the first network access device may move toward the second network access device to be close to the second network access device. In one possible implementation, there may be a mobility power module in the first network access device for controlling the first network access device to move. The mobile power module may be activated to move when the first network access device needs to move. For example, a moving wheel may be installed on the first network access device, and the first network access device may move through rolling of the moving wheel, and for example, a flying apparatus may be installed on the first network access device, and the first network access device may fly based on the flying apparatus.

The condition that the first network access device stops moving is as follows: and detecting that the signal intensity of the second network access equipment is greater than a signal intensity threshold value, the time difference between the sending and receiving signals of the first network access equipment and the second network access equipment is less than a time threshold value, and the distance between the first network access equipment and the second network access equipment is less than a distance threshold value, or acquiring identification information of the second network access equipment and successfully identifying the second network access equipment. When the above condition is met, it may be determined that the first network access device moves into a corresponding location range of the second network access device, and at this time, the first network access device may provide a wireless network access service for a terminal within a signal coverage range of the second network access device.

The above provides four conditions for the first network access device to stop moving, and for the first three conditions, the first network access device detects that the signal strength of the second network access device is greater than the signal strength threshold, and the time difference between the signals sent and received by the first network access device and the second network access device is smaller than the time threshold, which may indicate that the distance between the first network access device and the second network access device is short, and the signal coverage areas of the first network access device and the second network access device have an overlapping area. Of course, the stop movement may also be determined directly on the basis of the distance between the two.

For a fourth condition, the second network access device may display identification information of the second network access device, the identification information being used for the first network access device to collect and identify the second network access device. The first network access equipment can collect images in the moving process, identifies the identification information in the collected images, and stops moving when the identification result indicates that the identification information in the images is the identification information of the second network access equipment. Further, the identification information of the second network access device may be generated based on the identification information of the second network access device. For example, the identification information of the second network access device may be an identification code, such as a two-dimensional code or a barcode, and the identification code may be generated based on the ssid and/or bssid of the second network access device.

Of course, the above only provides four ways, and the first network access device may also determine that the first network access device has moved into the location range corresponding to the second network access device through other ways to stop moving, which is not limited in the embodiment of the present invention.

For example, as shown in fig. 7, the second network access device may send a wireless network capacity expansion help-seeking request when a network access load condition of the second network access device is in a problem, the first network access device may determine whether the first network access device has an assistance condition after receiving the wireless network capacity expansion help-seeking request, and the first network access device that meets the assistance condition sends a wireless network capacity expansion help-seeking response, so that the second network access device may receive the wireless network capacity expansion help-seeking response sent by the first network access device, and when the number of the received wireless network capacity expansion help-seeking responses is different, steps executed by the second network access device may be different. If multiple help seeking responses are received, the second network access device can determine a target first network access device from the multiple first network access devices, so that assistance invitation information is sent to the determined target first network access device, after the target first network access device receives the assistance invitation information, the position information of the second network access device can be obtained, a moving path is generated according to the position information, and the second network access device is driven to move to a corresponding position range of the second network access device, so that wireless network access service is provided for a terminal in a signal coverage range of the second network access device. If the number of the received wireless network capacity expansion help seeking responses is one, the second network access device does not need to determine the target first network access device, and only needs to directly send the assistance invitation information to the first network access device, and the first network access device can assist.

It should be noted that, in step 207 and step 208, a manner in which the first network access device provides the wireless network capacity expansion service for the second network access device is provided, in which the wireless network capacity expansion help seeking response is used to inform that the first network access device can move towards the second network access device according to the location information of the second network access device until entering a corresponding location range capable of providing the wireless network access service for the terminal within the signal coverage range of the second network access device.

The first network access device may also provide a wireless network capacity expansion service for the second network access device in other manners. In one possible implementation, the steps 207 and 208 may be replaced by: the first network access device adjusts the direction of sending and receiving signals according to the direction of the second network access device relative to the first network access device.

In this alternative, the wireless network capacity expansion help-seeking response is used to inform the first network access device that the direction of sending and receiving signals can be adjusted according to the direction of the second network access device relative to the first network access device.

The first network access device may have a function of adjusting a direction in which signals are transmitted and received, for example, the first network access device may adjust the direction in which signals are transmitted and received by adjusting an antenna direction. A first network access device may acquire the orientation of a second network access device relative to the first network access device,

in a possible implementation manner, the first network access device may adjust a direction in which the first network access device sends and receives a signal, and during the adjustment, detect the signal strength of the second network access device until the signal strength is detected to reach a preset condition. Specifically, the preset condition may be preset by a related technician, for example, the signal strength reaching the preset condition may be that the signal strength reaches a maximum value, that is, a direction in which a signal is transmitted and received when the detected signal strength is maximum is taken as a direction of the second network access device relative to the first network access device.

In another possible implementation manner, the first network access device may obtain location information of the second network access device, and determine, based on the location information of the first network access device and the location information of the second network access device, a direction of the second network access device relative to the first network access device, and the first network access device may obtain a direction adjustment value according to the direction of the second network access device relative to the first network access device and a current direction of transmitting and receiving a signal, so as to adjust a direction of transmitting and receiving the signal according to the direction adjustment value. The process of acquiring the direction adjustment value by the first network access device based on the position information of the two devices and the current direction may be implemented based on a preset algorithm, and the preset algorithm may be preset by a related technician, which is not limited in the embodiment of the present invention.

In another possible implementation, the steps of step 207 and step 208 may be replaced by: the first network access device provides network data for the terminal connected with the second network access device based on the information interaction with the second network access device.

In this alternative, the wireless network capacity expansion help-seeking response is used to inform the first network access device that the first network access device can provide network data for the terminal connected to the second network access device based on information interaction with the second network access device.

The first network access device may offload the second network access device, and when receiving a network data acquisition request sent by a terminal (a terminal within a signal coverage range) connected to the second network access device, the second network access device sends the network data acquisition request to the first network access device, so that the first network access device may receive the network data acquisition request forwarded by the second network access device, where the network data acquisition request is sent to the second network access device by the terminal connected to the second network access device, the first network access device acquires network data based on the network data acquisition request and then sends the network data to the second network access device, and the second network access device receives the network data sent by the first network access device and sends the network data to the terminal, that is, the second network access device may forward the network data to the terminal connected to the second network access device. The first network access device can share a part of network data acquisition requirements of the terminal for the second network access device, thereby realizing wireless network capacity expansion, optimizing the surrounding network environment of the network access device and solving the problems of network access device overload and network congestion.

The above only provides three possible implementation manners, and the first network access device may also provide the wireless network capacity expansion service for the second network access device through other manners, which is not limited in the embodiment of the present invention.

In the embodiment of the invention, the first network access equipment and the second network access equipment can interact, when the load condition of the second network access equipment meets a certain condition, a wireless network capacity expansion help seeking request can be sent to the first network access equipment, and when the first network access equipment meets an assistance condition, the first network access equipment can move to the position range corresponding to the second network access equipment to provide wireless network access service for the terminal in the signal coverage range of the second network access equipment, so that the number of the network access equipment which can be connected with the terminal in the signal coverage range is increased, the capacity expansion of the wireless network is realized, the network environment around the second network access equipment is optimized, and the problems of overload and network blockage of the second network access equipment can be solved.

All the above-mentioned optional technical solutions can be combined arbitrarily to form the optional embodiments of the present invention, and are not described herein again.

The above-mentioned specific flow of the wireless network capacity expansion method in the embodiment shown in fig. 2 is explained in detail, and a specific implementation example is provided below by the embodiment shown in fig. 8, in this embodiment, after the second network access device sends the wireless network capacity expansion help seeking request, the plurality of first network access devices send wireless network capacity expansion help seeking responses, the second network access device selects a target first network access device from the plurality of first network access devices, so as to invite the target first network access device, the target first network access device provides wireless network capacity expansion service for the second network access device by moving to the position range corresponding to the second network access device, the target first network access equipment and the second network access equipment determine the direction through communication, and stop moving when certain conditions are met. Fig. 8 is a flowchart of a method for expanding a wireless network according to an embodiment of the present invention, and referring to fig. 8, the method may include the following steps:

801. and the second network access equipment acquires the network access load condition of the second network access equipment.

802. And when the network access load condition meets a second target condition, the second network access equipment sends a wireless network capacity expansion help seeking request.

803. And the first network access equipment receives a wireless network capacity expansion help seeking request sent by the second network access equipment.

806. And the second network access equipment receives wireless network capacity expansion help seeking responses of the plurality of first network access equipment.

Steps 801 to 806 are similar to steps 201 to 206, and the embodiment of the present invention is not repeated herein. It should be noted that, in this embodiment, only the second network access device receives the wireless network capacity expansion help-seeking responses of the multiple first network access devices as an example for description, and of course, the second network access device may also receive only one wireless network capacity expansion help-seeking response of the first network access device, which is not limited in this embodiment of the present invention.

807. And the second network access equipment acquires the target first network access equipment according to the wireless network capacity expansion help seeking response of the plurality of first network access equipment.

808. The second network access device sends assistance invitation information to the target first network access device.

In steps 807 and 808, similar to the first step and the second step shown in step 206, the second network access device receives the wireless network capacity expansion help-seeking responses of the plurality of first network access devices, and may select the target first network access device from the plurality of first network access devices, so as to send the assistance invitation information to the target first network access device, so as to instruct the target first network access device to perform the following steps for moving. For details, the obtaining process of the target first network access device and the process of sending the assistance invitation information may refer to the contents of the step one and the step two shown in the step 206, and details of the embodiment of the present invention are not repeated herein.

809. The target first network access device receives assistance invitation information of the second network access device.

After receiving the assistance invitation information of the second network access device, the target first network access device may determine to move to the location range corresponding to the second network access device for assistance. The target first network access device may perform the steps of determining a direction of movement and moving, and stopping the movement when certain conditions are met.

810. The target first network access equipment sends positioning signals to a plurality of directions, and the positioning signals in each direction carry direction indication information corresponding to the direction.

811. And the second network access equipment receives a positioning signal of the target first network access equipment, wherein the positioning signal carries direction indication information corresponding to a certain direction.

813. And the target first network access equipment receives the response signal sent by the second network access equipment and extracts the direction indication information carried by the response signal.

The process from step 810 to step 813 is the process of acquiring the location information of the second network access device for the target first network access device, and the process is the same as the process in step 207, and the target first network access device may determine the location of the second network access device through communication between the target first network access device and the second network access device.

Step 814 and step 815 are similar to step one and step two in step 208, and the embodiment of the present invention is not described herein again.

For example, as shown in fig. 9, in one particular example, the first network access device and the second network access device may both be Wi-Fi devices. The first network access device and the second network access device may include a signal receiving module, a signal transmitting module, a Wi-Fi connection module, a signal processing module, a load evaluation module, a device information reading module, a visual module, a projection module, a positioning module, a mobile power module, and the like, wherein functions of the respective modules may be as follows:

after receiving the assistance invitation information, the target first network access device may determine whether the assistance invitation information is sent to the device, specifically, may extract device information (ssid and bssid) of the device to be invited in the assistance invitation information, determine whether the device information (ssid and bssid) is device information of its own, that is, determine whether the ssid and bssid are values of the device, if not, the assistance invitation information may be discarded, if so, after the target first network access device may determine which device the second network access device is, the preparation for addressing may be started, and a vision module is opened, where the vision module is used to collect an image and identify identification information in the collected image.

After the second network access device sends the assistance invitation information, the projection module may also be opened to project its own information outwards, that is, to display the identification information of the second network access device, so that the target first network access device may scan the identification information through the vision module and identify the identification information, and confirm the identity of the second network access device. The second network access device opens the projection module, makes the information including self ssid, bssid and the like into a two-dimensional code, projects the two-dimensional code on the box of the self Wi-Fi device, and projects the two-dimensional code in all directions, for example, the two-dimensional code can be projected in four directions or six directions.

Further, after receiving the wireless network capacity expansion help seeking response of the target first network access device, the second network access device sends assistance invitation information to prepare for performing dialogue positioning with the target first network access device, taking the positioning signal as a sound wave and taking the sending direction as four directions as an example, the target first network access device sends a signal with four direction identifications (direction indication information) to the four directions through the directional sound wave of the positioning module, and after receiving the directional sound wave, the second network access device analyzes the information contained in the directional sound wave and sends the information in which direction the information is sent, and then feeds the direction information back to the target first network access device through the Wi-Fi signal sending module. The target first network access equipment starts flying to the confirmed direction through the mobile power module after confirming the direction, and constantly sends directional sound waves to the second network access equipment in the flying process, so that the flying direction of the target first network access equipment is constantly adjusted.

When the target first network access equipment reaches the position near the second network access equipment, the vision module scans the two-dimensional code projected by the second network access equipment, the target first network access equipment analyzes the read two-dimensional code and sends the information to the second network access equipment for confirmation, and after the confirmation of the second network access equipment is completed, the target first network access equipment falls beside the second network access equipment to complete the task of searching the position of the second network access equipment. The target first network access device provides wireless network access service for terminals within the signal coverage of the second network access device.

Furthermore, the network access equipment which has little influence on the terminal connection condition in the original signal coverage after movement can be selected to move, so that the conditions of new network congestion which cannot be generated are ensured while the expansion of a wireless network is carried out, the network environment around the network access equipment seeking help is optimized, and the problems of overload and network congestion of the network access equipment are solved.
