The embodiments described below are some, but not all embodiments of the disclosure.

All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. Embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
In the related art, the roaming processing mechanism of the Mesh network to the associated wireless client is generally to monitor the uplink signal strength of the associated wireless client. When the uplink signal strength of the wireless client is lower than the signal threshold, a wireless signal measurement request is sent to the wireless client, and the wireless client scans a Service Set Identifier (SSID) list around the wireless client based on the wireless signal measurement request and returns a scanning result to the wireless access point. And the wireless access point of the current associated wireless client evaluates whether a better wireless access point is available for the wireless client to connect according to the measurement result. If yes, suggesting the wireless client to roam and connect with the suggested wireless access point; if not, the measurement process is performed periodically again to continue to evaluate whether a better wireless access point is available for the wireless client to connect to.
If the area where the wireless client is located is a weak wireless signal area and no other wireless access point is available for roaming in the area, on one hand, the power consumption of the wireless client is increased in the process of periodically performing wireless signal measurement scanning by the wireless client, and on the other hand, the wireless client intermittently performs scanning to occupy communication resources, so that interference is caused to normal communication of the wireless client.
The wireless signal measurement method provided by the embodiment of the disclosure transmits a wireless signal measurement request to a wireless client based on a first time interval, and when it is monitored that the uplink signal intensity of the wireless client is smaller than a measurement trigger threshold and there is no target wireless access point for roaming of the wireless client, the wireless signal measurement request is transmitted to the wireless client again by increasing the time interval, that is, based on a second time interval, so as to reduce the frequency of the wireless client executing the wireless signal measurement request. And then reduce the power consumption of the wireless client, and avoid the wireless client to the interference of the normal communication of the wireless client in the course of carrying out the measurement request of the wireless signal.
Fig. 1 is a schematic diagram illustrating an application scenario of a wireless signal measurement method according to an exemplary embodiment.
The wireless signal measurement method provided by the embodiment of the disclosure can be applied to a wireless access point, wherein the wireless access point is associated with a wireless client. It is understood that the wireless client is a device that needs to connect to the wireless access point to implement a communication function, for example, the wireless client may include a mobile terminal or a tablet computer.
As shown in fig. 1, under the coverage of the internet 101, a first wireless access point 102 and a second wireless access point 103 are included. In an example, the second wireless access point 103 has associated with it a wireless client 104, and if the current uplink signal strength of the wireless client 104 is less than the measurement trigger threshold (it can be understood that the wireless client 104 is in a weak wireless signal area), and no other wireless access point (e.g., the first wireless access point 102) is detected to be available for roaming based on the wireless measurement report, the wireless client 104 can decrease the frequency of the wireless client 104 performing the wireless signal measurement request by increasing the time interval for sending the wireless signal measurement request to the wireless client 104. Thereby reducing power consumption of wireless client 104 and avoiding interference of wireless client 104 with normal communications of wireless client 104 during execution of wireless signal measurement requests.
Fig. 2 is a flow chart illustrating a method of wireless signal measurement according to an example embodiment.
In an exemplary embodiment of the present disclosure, the wireless signal measurement method may be applied to a wireless access point, where the wireless access point has a wireless client associated therewith. As shown in fig. 2, the wireless signal measurement method may include steps S11 to S13. The steps will be described separately below.
In step S11, the uplink signal strength of the wireless client is monitored.
In step S12, in response to that the uplink signal strength of the wireless client is less than a measurement trigger threshold for triggering the wireless client to perform wireless signal measurement, a wireless signal measurement request is sent to the wireless client based on the first time interval, and a wireless measurement report fed back by the wireless client is obtained.
In one embodiment, the wireless client's upstream signal strength may be monitored. Wherein the uplink signal strength of the wireless client is a signal strength generated based on the wireless access point currently associated with the wireless client. Whether the wireless client is currently in a weak wireless signal area can be determined based on the uplink signal strength of the wireless client. In one example, when the uplink signal strength of the wireless client is detected to be less than a measurement trigger threshold for triggering the wireless client to make wireless signal measurements, it can be understood that the wireless client is currently in a weak wireless signal region.
It should be noted that the measurement trigger threshold may be determined according to actual situations, and in the present disclosure, the measurement trigger threshold is not specifically limited.
In one embodiment, a wireless signal measurement request may be sent to a wireless client based on a first time interval when the wireless client is detected to be in a weak wireless signal region. The wireless client may scan its surrounding SSID lists based on wireless signal measurement requests and feed back the scan results in the form of wireless measurement reports. The wireless measurement report may include information of the wireless access point where the wireless client may roam.
In step S13, if it is determined that there is no target wireless access point for the wireless client to roam based on the wireless measurement report, the wireless signal measurement request is transmitted to the wireless client again based on the second time interval. Wherein the second time interval is greater than the first time interval.
In one embodiment, if it is determined that there is no target wireless access point for the wireless client to roam around based on the wireless measurement report, the time interval for sending the wireless signal measurement request may be increased, i.e., the wireless signal measurement request is sent to the wireless client again based on the second time interval. It is understood that the second time interval is greater than the first time interval. In this way, the frequency with which wireless clients perform wireless signal measurement requests may be reduced.
It should be noted that, during the application process, the uplink signal strength of the wireless client may be monitored in real time, and it may be determined whether the wireless client is in the weak signal area based on the uplink signal strength. Further, when the wireless client receives a request for wireless signal measurement, the measurement request can be executed, and the downlink signal strength of the wireless access points around the wireless client can be monitored. In the application process, whether a target wireless access point for roaming of the wireless client exists around the wireless client can be determined based on the downlink signal strength.
It should be noted that the frequency for monitoring the uplink signal strength of the wireless client may be different from the frequency for monitoring the downlink signal strength of the wireless access point around the wireless client. For example, the uplink signal strength of the wireless client may be monitored every 1 second, and the downlink signal strength of the wireless access points around the wireless client may be monitored every 3 seconds. Or monitoring the downlink signal strength of the wireless access points around the wireless client in a manner of increasing the interval time every time (for example, the time for monitoring the downlink signal strength for the first time is 1 st second, the time for monitoring the downlink signal strength for the second time is 3 rd second, and the time for monitoring the downlink signal strength for the third time is 6 th second).
The wireless signal measurement method provided by the embodiment of the disclosure transmits a wireless signal measurement request to a wireless client based on a first time interval, and when it is monitored that the uplink signal strength is smaller than a measurement trigger threshold and a target wireless access point for roaming of the wireless client does not exist, the wireless signal measurement request is transmitted to the wireless client again by increasing the time interval, that is, based on a second time interval, so as to reduce the frequency of the wireless client executing the wireless signal measurement request. And then reduce the power consumption of the wireless client, and avoid the wireless client to the interference of the normal communication of the wireless client in the course of carrying out the measurement request of the wireless signal.
The present disclosure will explain a procedure of initiating a wireless signal measurement request to the wireless client again based on the second time interval by the following embodiments.
Fig. 3 is a flow chart illustrating a re-initiation of a wireless signal measurement request to a wireless client based on a second time interval in accordance with an example embodiment.
In an exemplary embodiment of the present disclosure, as shown in fig. 3, initiating the wireless signal measurement request to the wireless client again based on the second time interval may include steps S21 and S22, which will be described separately below.
In step S21, in response to the second time interval being greater than the preset maximum time interval threshold, a wireless signal measurement request is initiated to the wireless client again based on the maximum time interval threshold.
In step S22, in response to the second time interval being less than or equal to the preset maximum time interval threshold, a wireless signal measurement request is initiated to the wireless client again based on the second time interval.
In one embodiment, when the wireless client is in a weak wireless signal area and there is no target wireless access point for the wireless client to roam, the time interval may be increased, i.e., a wireless signal measurement request may be initiated to the wireless client again based on the second time interval. In the process of initiating the wireless signal measurement request to the wireless client again by using the second time interval and scanning other wireless access points available for roaming of the wireless client based on the wireless signal measurement request, in order to ensure roaming experience, the duration of the second time interval is not infinitely increased. In an example, when the second time interval is greater than a preset maximum time interval threshold, a wireless signal measurement request may be initiated again to the wireless client based on the maximum time interval threshold. In another example, when the second time interval is less than or equal to a preset maximum time interval threshold, the wireless signal measurement request may be initiated again to the wireless client based on the second time interval. It should be noted that the maximum time interval threshold may be determined according to actual situations, for example, the maximum time interval threshold may be 5 seconds, and in the present disclosure, the maximum time interval threshold is not specifically limited.
The present disclosure will explain the procedure of the wireless signal measurement method by the following embodiments.
Fig. 4 is a flow chart illustrating another method of wireless signal measurement according to an example embodiment.
In an exemplary embodiment of the present disclosure, as shown in fig. 4, the method for measuring a wireless signal may include steps S31 to S34, where steps S31 to S33 are respectively the same as steps S11 to S13, and please refer to the foregoing for specific implementation and beneficial effects thereof, which are not repeated in the present disclosure. Step S34 will be described in detail below.
In step S34, if it is determined that the uplink signal strength of the wireless client is higher than the set first signal strength threshold and/or it is determined that a target wireless access point for roaming of the wireless client exists, a wireless signal measurement request is sent to the wireless client at a first time interval.
In an embodiment, when it is monitored that the uplink signal strength of the wireless client is higher than the set first signal strength threshold, it may be understood that the wireless client currently has the uplink signal strength with the higher strength, that is, the wireless client is not currently located in the weak wireless signal area. At this time, the wireless signal measurement request may be transmitted to the wireless client again at the first time interval without increasing the time interval for transmitting the wireless signal measurement request.
The set first signal strength threshold may be adjusted according to actual conditions, and in the present disclosure, the set first signal strength threshold is not specifically limited.
In another embodiment, when it is monitored that a target wireless access point for roaming of the wireless client exists around the wireless client, it can be understood that the wireless client currently has a better target wireless access point for roaming and connection. At this time, the wireless signal measurement request may be transmitted to the wireless client again at the first time interval without increasing the time interval for transmitting the wireless signal measurement request. In the application process, whether a target wireless access point for roaming of the wireless client exists around the wireless client can be determined based on the wireless measurement report fed back by the wireless client, and a foundation is laid for the wireless client to be connected to the wireless access point capable of generating higher wireless signal strength.
The present disclosure will explain the procedure of the wireless signal measurement method by the following embodiments.
Fig. 5 is a flow chart illustrating yet another method of wireless signal measurement according to an example embodiment.
In an exemplary embodiment of the present disclosure, as shown in fig. 5, the method for measuring a wireless signal may include steps S41 to S44, where steps S41 to S43 are respectively the same as steps S11 to S13, and please refer to the foregoing for specific implementation and beneficial effects thereof, which are not repeated in the present disclosure. Step S44 will be described in detail below.
In step S44, if it is determined that the uplink signal strength of the wireless client is lower than the set first signal strength threshold and there is no target wireless access point for the wireless client to roam, the second time interval is increased, and the second time interval after the increase of the time interval is used as a new second time interval, and a wireless signal measurement request is initiated to the wireless client.
In an embodiment, when it is detected that the uplink signal strength of the wireless client is lower than the set first signal strength threshold and there is no target wireless access point for roaming of the wireless client, it may be understood that the wireless client is in a weak wireless signal area and there is no target wireless access point for roaming of the wireless client. At this time, the time interval may be increased, and a wireless signal measurement request may be initiated again to the wireless client based on the increased time interval. By the method, the frequency of the wireless client for executing the wireless signal measurement request can be reduced, so that the power consumption of the wireless client is reduced, and the interference of the wireless client on the normal communication of the wireless client in the process of executing the wireless signal measurement request is avoided.
In an example, when the wireless client is in a weak wireless signal area and there is no target wireless access point for roaming of the wireless client, the second time interval may be increased, and the step of initiating a wireless signal measurement request to the wireless client is performed cyclically again with the second time interval after the increased time interval as a new second time interval. It is to be understood that, in the process of performing the wireless signal measurement request, the frequency of performing the wireless signal measurement request by the wireless client may be reduced due to the addition of the second time interval. And then reduce the power consumption of the wireless client, and avoid the wireless client to the interference of the normal communication of the wireless client in the course of carrying out the measurement request of the wireless signal.
The present disclosure will explain the procedure of still another wireless signal measurement method by the following embodiments.
Fig. 6 is a flow chart illustrating yet another method of wireless signal measurement according to an example embodiment.
In an exemplary embodiment of the present disclosure, as shown in fig. 6, the method for measuring a wireless signal may include steps S51 to S54, where steps S51 to S53 are respectively the same as steps S11 to S13, and please refer to the foregoing for detailed implementation and beneficial effects thereof, which are not repeated in the present disclosure. Step S54 will be described in detail below.
In step S54, if it is determined that the intensity difference between the uplink signal intensities of the wireless clients monitored when the wireless signal measurement request is sent to the wireless client twice in a row is greater than the set second signal intensity threshold, the wireless signal measurement request is sent to the wireless client at a first time interval.
In an embodiment, when it is monitored that the intensity difference of the uplink signal intensities of the wireless clients monitored when the wireless signal measurement requests are sent to the wireless clients twice in a neighboring period is greater than the set second signal intensity threshold, it may be understood that the wireless client currently has the uplink signal intensity with a higher intensity, that is, the wireless client is not currently located in the weak wireless signal area. At this time, the wireless signal measurement request may be transmitted to the wireless client again at the first time interval without increasing the time interval for transmitting the wireless signal measurement request.
It should be noted that the set second signal strength threshold may be adjusted according to actual situations, and in the present disclosure, the set second signal strength threshold is not specifically limited.
As can be seen from the foregoing description, the frequency of monitoring the uplink signal strength of the wireless client and the frequency of sending the wireless signal measurement request may be different. In one example, the wireless client's uplink signal strength may be monitored every 1 second interval. For example, the time for monitoring the uplink signal strength of the wireless client for the first time is 1 st second, the time for monitoring the uplink signal strength of the wireless client for the second time is 2 nd second, the time for monitoring the uplink signal strength of the wireless client for the third time is 3 rd second, and the time for monitoring the uplink signal strength of the wireless client for the fourth time is 4 th second. The wireless signal measurement request can be sent every 3 seconds, and the downlink signal strength of the wireless access point is monitored. For example, the time when the radio signal measurement request is transmitted for the first time is 1 st second, and the time when the radio signal measurement request is transmitted for the second time is 4 th second. It should be noted that the intensity difference of the uplink signal strength of the wireless client monitored when the wireless signal measurement request is sent to the wireless client twice in the adjacent time can be understood as the intensity difference of the uplink signal strength of the wireless client monitored in the 4 th second and the uplink signal strength of the wireless client monitored in the 1 st second.
In another embodiment, when it is monitored that the intensity difference of the uplink signal intensities of the wireless clients monitored when the wireless signal measurement requests are sent to the wireless clients twice in a neighboring manner is greater than the set second signal intensity threshold, it can also be understood that the wireless clients are currently moving, and thus have stronger uplink signal intensities, that is, the wireless clients are not currently located in a weak wireless signal area. At this time, the wireless signal measurement request may be transmitted to the wireless client again at the first time interval without increasing the time interval at which the wireless signal measurement request is transmitted.
Fig. 7 is a flow chart illustrating yet another method of wireless signal measurement according to an example embodiment.
To further explain the wireless signal measurement method, the present disclosure will be described with reference to fig. 7.
In an exemplary embodiment of the present disclosure, as shown in fig. 7, the wireless signal measurement method may include steps S501 to S513, which will be described below.
In step S501, it is determined whether the wireless client has measurement and roaming management capabilities.
In step S502, the uplink signal strength of the wireless client is monitored.
In one embodiment, when a wireless Access Point (AP) in the Mesh network associates with a wireless client, the AP may determine whether the wireless client has a BSS Transmission Management (BTM) capability of 11 k/11V. If the wireless client has the measurement and roaming management capability, the uplink signal strength of the wireless client can be continuously monitored. If the wireless client does not have the measurement and roaming management capability, the whole process is ended.
In step S503, it is determined whether the uplink signal strength is less than the measurement trigger threshold.
In step S504, a measurement request is initiated and a measurement report is received.
In one embodiment, it may be determined whether the uplink signal strength is less than a measurement trigger threshold based on the monitored uplink signal strength of the wireless client.
In one example, if the uplink signal strength is less than the measurement trigger threshold, it can be understood that the wireless client is in a weak wireless signal area. A wireless signal measurement request may be sent to a wireless client while the wireless client is in a weak wireless signal area. The wireless client may scan its surrounding SSID lists based on wireless signal measurement requests and feed back the scan results in the form of wireless measurement reports. The wireless measurement report may include information of the wireless access point where the wireless client may roam.
In another example, if the uplink signal strength is greater than or equal to the measurement trigger threshold, it may be understood that the wireless client is not in a weak wireless signal area. At this point, the step of monitoring the uplink signal strength of the wireless client may be returned to.
In step S505, it is determined whether another AP within the Mesh network is detected.
In step S506, the time interval of the next measurement request is increased.
In one embodiment, the AP currently associated with the wireless client determines whether there is a target AP for the wireless client to roam, i.e., other APs within the Mesh network, by analyzing the wireless measurement report.
In an example, if the wireless measurement report does not have a target AP for roaming of the wireless client, it can be understood that the wireless client is in a weak wireless signal area, and there is no target AP for roaming of the wireless client. At this time, the time interval for initiating the next wireless signal measurement request is increased, and the frequency of the wireless client for executing the wireless signal measurement request is further reduced, so that the purposes of reducing the power consumption of the wireless client and avoiding the interference of the wireless client on the normal communication of the wireless client in the process of executing the wireless signal measurement request are achieved.
In another example, if there is a target AP for roaming of the wireless client in the wireless measurement report, the wireless client may be directly guided to roam and associate to the target AP without increasing the time interval for initiating the wireless signal measurement request next time, so as to provide higher uplink signal strength for the wireless client.
In step S507, it is determined whether the time interval is greater than a set maximum time.
In step S508, a new time interval is waited for, and the uplink signal strength is continuously monitored during the waiting period.
In step S509, the maximum time is set to wait, and the uplink signal strength is continuously monitored during the waiting period.
In step S510, a measurement request is executed and a report is returned.
In one embodiment, when the wireless client is in a weak wireless signal area and there is no target wireless access point for the wireless client to roam, the time interval for the next wireless signal measurement request initiation may be increased. It should be noted that, in the process of scanning other wireless access points available for roaming of the wireless client based on the wireless signal measurement request, in order to ensure the roaming experience, the duration of the time interval is not increased indefinitely. In one example, it may be determined whether the increased time interval is greater than a set maximum time. If the increased time interval is greater than or equal to the set maximum time, the set maximum time may be waited for, and the uplink signal strength may be continuously monitored during the waiting period. If the increased time interval is smaller than the set maximum time, the increased time interval can be waited, and the uplink signal strength is continuously monitored during the waiting period.
Further, after the step of continuously monitoring the uplink signal strength during the waiting period is performed, the wireless client may perform a wireless signal measurement request and feed back a wireless measurement report.
It should be noted that the time interval for the wireless client to initiate the wireless signal measurement request next time is not infinitely increased in the application process. The time interval for the wireless client to initiate the wireless signal measurement request again is positively correlated with the number of times that no target wireless access point for roaming is available in the continuously acquired wireless measurement report. In an example, in the weak radio signal area, if the time interval for the wireless client to initiate the radio signal measurement request for the first time is 1 second, when it is detected that there is no target wireless access point for roaming currently, the time interval for the wireless client to initiate the radio signal measurement request again may be 2 seconds. Further, when it is detected again that there is no target wireless access point for roaming, the time interval for the wireless client to initiate the wireless signal measurement request again may be 3 seconds. By the method, the frequency of the wireless client for executing the wireless signal measurement request can be reduced, so that the power consumption of the wireless client is reduced, and the interference of the wireless client on the normal communication of the wireless client in the process of executing the wireless signal measurement request is avoided.
In step S511, whether the difference between the current uplink signal strength and the previous uplink signal strength is greater than a predetermined value or other APs for roaming exist.
In step S512, the wireless client is guided to roam.
In step S513, the process ends.
In an embodiment, when it is monitored that the intensity difference of the uplink signal intensity of the wireless client monitored when the wireless signal measurement request is sent to the wireless client twice in a neighboring period is higher than a set value, it can be understood that the wireless client currently has a position movement, and thus has a stronger uplink signal intensity, that is, the wireless client is not currently located in a weak wireless signal area. At this time, without increasing the time interval for sending the wireless signal measurement request, the wireless client may be guided to roam and associate to the target AP, so as to provide higher uplink signal strength for the wireless client.
In another embodiment, when it is monitored that a target AP for roaming of the wireless client exists around the wireless client, it can be understood that the wireless client currently has a better target AP for roaming. At this time, without increasing the time interval for sending the wireless signal measurement request, the wireless client may be guided to roam and associate to the target AP, so as to provide higher uplink signal strength for the wireless client.
As can be seen from the foregoing description, in the wireless signal measurement method provided in the embodiments of the present disclosure, the wireless signal measurement method sends a wireless signal measurement request to the wireless client based on a first time interval, and when it is monitored that the uplink signal strength is smaller than the measurement trigger threshold and there is no target wireless access point for the wireless client to roam, the wireless signal measurement method sends the wireless signal measurement request to the wireless client again by increasing the time interval, that is, based on a second time interval, so as to reduce the frequency of the wireless client performing the wireless signal measurement request. And then reduce the power consumption of the wireless client, and avoid the wireless client to the interference of the normal communication of the wireless client in the course of carrying out the measurement request of the wireless signal.
