The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Referring to fig. 1, fig. 1 is a system framework diagram of a wireless roaming method according to an embodiment of the present disclosure. As shown in fig. 1, the wireless roaming system includes a terminal device 101 and an Access Point (AP) 102. Among them, the terminal device 101 may also be called a Station (STA), and the terminal device 101 in the coverage of the wireless access point 102 may communicate through the wireless access point. The wireless access point 102 may convert a wired local area network to a wireless local area network to provide mutual access between the terminal device and the wired local area network. The number of the wireless access points 102 shown in fig. 1 is only an example, and the application does not limit the number of the access points. The wireless access point 102 may be multiple, for example: the wireless access point to which the terminal device 101 is currently connected, other wireless access points, and the like.
The terminal device may include, but is not limited to: smart phones (such as Android phones, iOS phones, etc.), tablet computers, portable personal computers, Mobile Internet Devices (MID for short), smart terminals (such as smart watches, bracelets, smart speakers, etc.), and the like.
The wireless roaming method provided by the present application is explained based on the system framework of the wireless roaming method. Referring to fig. 2, fig. 2 is a flowchart illustrating a wireless roaming method according to an embodiment of the present application, and as shown in fig. 2, the wireless roaming method includes, but is not limited to, the following steps:
s201: if the signal strength value of the currently connected second AP is lower than the signal threshold or the beacon loss number reaches the roaming threshold, the terminal device searches whether the information of one or more first roaming APs is stored.
When the signal strength value of the currently connected second AP is lower than the signal threshold or the beacon loss number reaches the roaming threshold, which indicates that the signal quality of the wireless network is poor and is not enough to support the current user service, the terminal device may be triggered to roam, and it is searched whether information of one or more first roaming APs is stored.
The signal threshold and the roaming threshold may be set by a user according to an actual application, and the embodiment of the present application is not limited. The second AP is the AP to which the terminal device is connected before triggering roaming. The first roaming AP is an AP that meets roaming conditions. Exemplary roaming conditions include: the Service Set Identifier (SSID) of the first roaming AP is the same as the SSID of the second AP, and the encryption method of the first roaming AP is the same as the encryption method of the second AP. Optionally, the roaming condition may further include: the signal strength value of the first roaming AP is greater than the signal threshold or the number of beacon losses is less than the roaming threshold.
The information of the first roaming AP includes, but is not limited to, the MAC Address (Media access control Address) of the AP, the channel (channel), the signal strength, the load, and the timestamp when the AP is scanned. Optionally, the storage manner of the information of the first roaming AP is not limited. For example, an AP information table may be established in which information for one or more first roaming APs is stored. Illustratively, as shown in table 1, table 1 is one possible implementation form of the AP information table.
TABLE 1
| Indexing | MAC address | Channel with a plurality of channels | Time stamp | Signal strength | Load(s) | … |
| 000 | xxx | xxx | xxx | xxx | xxx | |
| … |
Optionally, the terminal device is connected to the second AP, and the background performs periodic full channel scanning during service processing through the wireless network provided by the second AP. And when the background carries out periodic full-channel scanning, updating the AP information table according to the scanned information of the first roaming AP. Namely, if the terminal device scans a new AP meeting roaming conditions in the current environment, the new AP is added to the AP information table. Therefore, in the process of moving the terminal equipment, the AP meeting the roaming condition can be found in real time. Optionally, if it is found that the information of the first roaming AP stored in the AP information table is changed during scanning, the information of the AP is updated. If the signal quality of the first roaming AP information is found not to meet the roaming condition, the AP may be deleted from the AP information table. In the process of moving the terminal device, it can be ensured that the APs in the AP information table are all APs meeting roaming conditions.
Optionally, a timestamp when the first roaming AP is scanned is recorded in the AP information table, the information of the first roaming AP whose aging time reaches the time threshold in the AP information table is deleted according to the timestamp, and the aging time represents a duration of the current time from the timestamp. The time threshold value can be set in a self-defined mode according to the practical application condition. Illustratively, the time threshold is 60 seconds, and if the aging time of the AP1 exceeds 60 seconds, the AP1 is deleted from the AP information table. In the moving process of the terminal equipment, the first roaming AP with the aging time exceeding the time threshold is deleted, so that the real-time performance of the AP information in the AP information table can be ensured. Meanwhile, the situation that the state of the first roaming AP is changed but the mobile terminal considers that the AP meets the roaming condition is avoided.
S202: if the information of the one or more first roaming APs is stored, the terminal device selects a target AP for roaming from the one or more first roaming APs.
Wherein the target AP represents an AP with the best signal quality among the one or more first roaming APs, and the signal quality may be determined according to a roaming AP selection algorithm. Such as calculating the signal quality of the AP from the signal strength and the load of the AP.
In a possible implementation manner, if information of a first roaming AP is stored, the first roaming AP is the target AP. The terminal equipment disconnects the second AP which is connected currently and connects to the first roaming AP. By the method, the terminal equipment can directly roam through the stored first roaming AP after roaming is triggered, so that the time spent on scanning the target AP for a long time before roaming is skipped, the roaming processing process is accelerated, and the influence of the roaming process on the normal service of a user can be reduced.
In one possible implementation, if information of a plurality of first roaming APs is stored, a target AP for roaming is selected from the plurality of first roaming APs according to a roaming AP selection algorithm. The terminal equipment disconnects the second AP which is connected currently and connects to the target AP. By the method, the terminal equipment can directly select the target AP from the stored multiple first roaming APs for roaming after triggering roaming, so that the time spent on scanning the target AP for a long time before roaming is skipped, the roaming processing process is accelerated, and the influence of the roaming process on the normal service of a user can be reduced.
In the embodiment of the application, when the signal strength value of the second AP currently connected with the terminal equipment is lower than the signal threshold value or the beacon loss number reaches the roaming threshold value, the terminal equipment is triggered to roam; the terminal equipment selects the AP with the best signal quality from the stored roaming APs meeting the roaming conditions for roaming. Therefore, by implementing the method and the device, the optimal target AP can be quickly and efficiently found for roaming, and the influence of a wireless roaming process on the service is reduced.
Referring to fig. 3, fig. 3 is a flowchart illustrating another wireless roaming method according to an embodiment of the present application, and as shown in fig. 3, the wireless roaming method includes, but is not limited to, the following steps:
s301: and if the signal strength value of the currently connected second wireless access point AP is lower than the signal threshold or the beacon loss number reaches the roaming threshold, searching whether the information of one or more first roaming APs is stored.
The implementation of this step can refer to the description in step S201 in the above description, and is not described herein again.
S302: if the information of the one or more first roaming APs is stored, a target AP for roaming is selected from the one or more first roaming APs.
The implementation of this step can refer to the description in step S202 in the above description, and is not described herein again.
S303: and if the information of one or more first roaming APs is not stored, searching whether the AP channel list information is stored or not.
The AP channel list information is used for recording the channel information of the AP which is the same as the SSID of the second AP. The AP channel list information includes, but is not limited to: after the terminal device is connected to the second AP, in the background scanning process, the channel information of the AP with the same SSID as the second AP and a different MAC address (also referred to as Basic Service Set, BSSID) is recorded. The storage mode of the AP channel list information is not limited, and may be a part in the AP information table, or may be an independent AP channel list. Illustratively, the AP channel list includes index values and channel information of the AP, and the index values correspond to the channel information of the AP one to one.
S304: and if the AP channel list information is stored, scanning channels in the channels recorded by the AP channel list information according to the SSID of the second AP.
Optionally, the terminal device configures the relevant scanning parameters after triggering the channel scanning. Exemplarily, configuring the scanned channel as a channel in an AP channel list; the SSID is designated as the SSID of the second AP and then scanned. Therefore, the scanning range of the terminal device becomes smaller, and the computing resources of the terminal device can be reduced.
S305: if one or more third roaming APs are scanned, a target AP for roaming is selected from the one or more third roaming APs.
Wherein the third roaming AP is a scanned AP meeting the roaming condition. In the scanning process, if a beacon or a probe response frame (probe response) replied by one or more APs is received, it indicates that the scanned one or more third roaming APs meet the roaming condition. It should be noted that, if the third roaming AP replies the beacon or the probe response frame, it indicates that the SSID of the third roaming AP is the same as the SSID of the second AP, and the encryption method of the third roaming AP is the same as the encryption method of the second AP.
Optionally, the terminal device calculates roaming values of one or more third roaming APs according to a roaming AP selection algorithm; selecting a third roaming AP with the largest roaming value as a target AP; wherein the roaming value is used to indicate the load capacity and signal strength of the AP in the one or more third roaming APs, and the larger the roaming value is, the better the signal quality of the AP is. Optionally, an index value of a target AP having a largest roaming value among the plurality of third roaming APs is recorded. And after the scanning is finished, roaming to the target AP according to the index value.
Optionally, after roaming is successful, the roaming AP channel information recorded in the AP channel list is eliminated. The roaming AP channel information is then re-recorded based on the target AP (which may be understood as a new second AP) to form an AP channel list. Because the terminal equipment is in a mobile state, the roaming AP channel information recorded in the AP channel list is continuously updated, and the information of the roaming AP channel can be ensured to be real-time and accurate from one environment to another new environment.
In the embodiment of the application, when the signal strength value of the AP currently connected with the terminal equipment is lower than a signal threshold value or the loss number of beacons reaches a roaming threshold value, the terminal equipment is triggered to roam; if the terminal device does not find the stored roaming AP meeting the roaming condition, scanning again in the previously scanned channel recorded by the terminal device according to the SSID of the currently connected AP, and selecting the AP with the best signal quality for roaming after obtaining the roaming AP meeting the roaming condition. Therefore, by implementing the present application, the scanning range is reduced, the scanning results that the terminal device needs to process become less, and the computing resources of the terminal device can be reduced.
Referring to fig. 4, fig. 4 is a flowchart illustrating another wireless roaming method according to an embodiment of the present application, as shown in fig. 4, the wireless roaming method includes, but is not limited to, the following steps:
s401: and if the signal strength value of the currently connected second wireless access point AP is lower than the signal threshold or the beacon loss number reaches the roaming threshold, searching whether the information of one or more first roaming APs is stored.
S402: if the information of the one or more first roaming APs is stored, a target AP for roaming is selected from the one or more first roaming APs.
S403: and if the information of one or more first roaming APs is not stored, searching whether the AP channel list information is stored or not.
S404: and if the AP channel list information is stored, scanning channels in the channels recorded by the AP channel list information according to the SSID of the second AP. Then, step S406 is performed.
The implementation of steps S401 to S404 can refer to the description of steps S301 to S304 in the above description, and the description thereof is omitted here.
S405: and if the AP channel list information is not stored, performing full channel scanning according to the SSID of the second AP.
And after triggering full channel scanning, the terminal equipment configures relevant scanning parameters. Illustratively, the SSID is designated as the SSID of the second AP, and then a full channel scan is performed. Therefore, only the AP with the SSID same as that of the second AP responds to the full channel scan of the terminal device and feeds back a probe response frame; the APs with different SSIDs from the SSID of the second AP do not respond to the full channel scan of the terminal device; the scanning results that the terminal device needs to process become less, and the computing resources of the terminal device can be reduced. Meanwhile, the appointed SSID is the same as the SSID of the currently connected AP during scanning, so that the problem that the roaming AP with the hidden SSID cannot be scanned is solved.
S406: if one or more third roaming APs are scanned, a target AP for roaming is selected from the one or more third roaming APs.
The implementation of step S406 can refer to the description of step S305 in the above description, and is not repeated here.
S407: if one or more third roaming APs are not scanned, the scanning frequency of the full channel scan is decreased.
And if the target AP meeting the roaming condition is not found in the current environment, reducing the scanning frequency of full channel scanning. It should be noted that, each time the full channel scan is performed, the SSID needs to be designated as the SSID of the second AP. For example, if the time interval of the terminal device originally performing the full channel scanning is 10 seconds, but the target AP meeting the roaming condition is not found in the current environment, the time interval of the scanning may be increased to 15 seconds. By reducing the scanning frequency, further deterioration of the user network can be avoided.
In the embodiment of the application, when the signal strength value of the AP currently connected with the terminal equipment is lower than a signal threshold value or the loss number of beacons reaches a roaming threshold value, the terminal equipment is triggered to roam; if the terminal device does not find the stored roaming AP meeting the roaming condition and does not find the recorded previously scanned channel, performing full channel scanning of the specified SSID; and if the roaming AP meeting the roaming condition is not scanned in the full channel scanning, reducing the scanning frequency of the full channel scanning. Therefore, by implementing the present application, further deterioration of the user network can be avoided.
