Background
In WiFi technology, a mobile terminal is a Station (STA) in WiFi technology (where STA includes, but is not limited to, a mobile phone) and generally obtains network services by connecting to a wireless Access Point (AP).

A procedure in which a wireless mobile terminal changes from a current AP to another AP and maintains a network connection is called roaming.
The STA is a decision maker and an initiator of roaming behavior, and the STA actively switches the association relation with one AP to another AP in view of the mobile terminal, so that the purpose of always keeping connection with the wireless is realized.

Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
As shown in fig. 1, an embodiment of the present disclosure provides a method for determining a triggering condition of WiFi roaming, which is applied to a mobile terminal, and the method includes:
s110: positioning the mobile terminal to obtain positioning information;
s120: determining an application place of the geographic position of the mobile terminal according to the positioning information;
s130: and determining triggering conditions of the WiFi roaming of the mobile terminal according to the application places.
The mobile terminal provided by the embodiment of the disclosure comprises, but is not limited to, at least one of the following electronic devices: a cell phone, tablet, wearable device, or vehicle-mounted device.
In the embodiment of the disclosure, the mobile terminal can locate the position of the mobile terminal, so that the location information indicating the geographical position of the mobile terminal is obtained.
In one embodiment, the positioning information may include: longitude and latitude information, and the like. In one embodiment, the positioning information may be: distance information and/or azimuth information of the mobile terminal relative to a preset position.
For example, the mobile terminal may be located by satellite positioning. Satellite positioning herein includes, but is not limited to: global positioning system (Global Position System, GPS) positioning or beidou positioning.
Alternatively, the positioning of the mobile terminal may be positioning based on positioning technologies such as assisted positioning of the base station or ultrasound.
In summary, in the embodiment of the present disclosure, the mobile terminal may be able to locate its own location, and obtain location information.
Since the positioning information is positioned, the application place of the geographic position of the mobile terminal can be determined.
In one embodiment, in S120, the mobile terminal may query a local or server database with the positioning information as a query index, and determine the function or use of the positioning information, thereby determining the application location of the geographic location.
In another embodiment, in S120, the mobile terminal may query a geographic area to which the positioning information belongs, and determine an attribute of a WiFi AP covering the geographic area; if the attribute of the WiFi AP is a home WiFi AP, the application place of the current geographic position of the mobile terminal is a home scene, and if the attribute of the WiFi AP is a mall WiFi AP, the application place of the current geographic position of the mobile terminal is a mall scene.
Of course, the above is merely illustrative, and the application location of the current geographic location of the mobile terminal is determined according to the positioning information of the mobile terminal, which is not limited to any one of the above embodiments.
The WiFi APs at different application sites are provided with different characteristics, so that the WiFi coverage has different characteristics. In order to make the mobile terminal better access to the WiFi AP or obtain better communication quality, a WiFi roaming strategy which is currently effective for the mobile terminal is determined according to the application place of the geographic position of the mobile terminal.
The triggering conditions of the WiFi roaming at least include:
triggering the mobile terminal to perform WiFi roaming.
If the mobile terminal determines that WiFi roaming is currently required according to the triggering condition of WiFi roaming, and therefore the mobile terminal accesses to a WiFi AP with better communication quality, the mobile terminal can conduct WiFi scanning; if the WiFi broadcast signal of the adjacent WiFi AP is scanned, the WiFi AP is requested to be accessed through sending a detection request frame. If the adjacent WiFi AP receives the detection request frame, the relevant information for accessing the WiFi AP is sent to the mobile terminal through a detection response frame or a beacon frame.
In the embodiment of the disclosure, the triggering condition of the WiFi roaming of the mobile terminal is switched according to the application place where the mobile terminal is located, so that the triggering condition of the WiFi p roaming used by the mobile terminal accords with the WiFi coverage condition of the current application place, and the mobile terminal can access to the WiFi AP in time or to the WiFi AP with better communication quality.
Fig. 2 is a schematic flow chart of WiFi roaming of a mobile terminal, where the specific WiFi roaming includes:
in phase 1, trigger conditions, including, for example, but not limited to, configuring the trigger conditions of currently active WiFi roaming;
the roaming module is good in trigger condition based on RSSI in trigger conditions based on WiFi roaming, trigger conditions based on beacon frame loss or trigger conditions based on STA kick-off;
stage 2: at least one triggering condition is met, and roaming triggering is performed; the roaming trigger is the trigger of the WiFi roaming.
After the roaming scanning module receives the roaming trigger, notifying the scanning module to send a detection request frame; receiving a beacon response frame or a probe response frame;
stage 3: if the beacon response frame or the probe response frame is successfully received, the roaming switching module controls the mobile terminal to be connected to a new WiFi site;
If the roaming event is satisfied (e.g., a trigger condition for roaming is hit), roaming synchronous propagation is performed.
In one embodiment, as shown in fig. 4, the method further comprises:
s100: starting a geofence of the mobile terminal; the S110 may include: s111; and the S111 may include:
and after the geofence is started, positioning the mobile terminal to obtain the positioning information.
Geofencing (Geo-fencing) functionality is an application based on location services, which is to configure a virtual fence; the fence encloses a virtual boundary of a geographic area on the map. In fig. 3, black circles are the display effects of the configured virtual boundaries on the map.
The mobile terminal automatically monitors the self geographic position once started, and the mobile terminal triggers the geographic fence once entering into the geographic area surrounded by the virtual boundary or triggers the positioning module for positioning the mobile terminal based on various positioning technologies once the mobile terminal leaves the geographic area surrounded by the virtual boundary, so that the triggered triggering message of the geographic fence is reported. In this way, the application layer or operating system of the mobile terminal can be timely triggered based on whether the geofence is triggered. Once the geofence is triggered, the operational event that the geofence is trigger-bound is also triggered. In the disclosed embodiments, the operational events for which the geofence is triggered to bind include: determining event of triggering condition of WiFi roaming of the mobile terminal. The event of determining the triggering condition of the WiFi roaming of the mobile terminal may also be referred to as: update event of trigger condition of WiFi roaming of mobile terminal.
In one embodiment, the configuration of the geofence is required prior to the start of the geofence. The configuration of the geofence may include:
starting the geofence configuration, and displaying a page of the geofence configuration;
selecting coordinates and triggering precision of a geofence to be set in the page to obtain fence information;
and issuing the fence information to the positioning module.
The fence information includes, but is not limited to: the geofence encloses the coordinates and radius of the center point of the geographic area.
In one embodiment, the S120 may include:
determining whether the mobile terminal triggers the geofence based on the positioning information;
and responding to the mobile terminal to trigger the geofence, and determining the application place of the geographic position of the mobile terminal according to the positioning information.
If the current positioning information of the mobile terminal enters a geographic area corresponding to a geofence configured by the mobile terminal or a geographic area corresponding to the mobile geofence, the mobile terminal is triggered to redetermine the update of the application place of the current geographic position of the mobile terminal.
If the mobile terminal determines that the application location of the geographic location of the mobile terminal is changed, in S130, the WiFi roaming policy suitable for the current application location is redetermined according to the application location of the geographic location of the mobile terminal, so as to ensure that the mobile terminal can access to the WiFi AP with good communication quality or expected by the user in time.
In order to accelerate the mobile terminal to enter different application places, wi Fi roaming strategies suitable for the current application places can be quickly started. In the embodiment of the disclosure, a roaming preset trigger configuration is preconfigured in the mobile terminal, and the roaming preset trigger configuration may be a default trigger condition generally. Thus, considering the policy difference of different application sites, only the parameter value of the corresponding policy parameter in the preset trigger configuration or one or more trigger conditions in the preset trigger configuration for enabling or disabling roaming need to be modified, so as to take into effect the trigger conditions of WiFi roaming matched with the current use site Jing Shi.
Of course, in another embodiment, in S140, the mobile terminal may reconfigure according to the trigger condition of the WiFi roaming that is currently in effect, instead of modifying the preset trigger configuration of the roaming to obtain the trigger condition of the WiFi roaming that is currently in effect.
In one embodiment, the determining, according to the application location, a triggering condition of WiFi roaming by the mobile terminal includes:
a trigger condition that enables roaming of a preset trigger configuration with adaptation of the application field and/or a trigger condition that enables roaming of a preset trigger configuration with non-adaptation of the application field.
For example, the preset trigger configuration for roaming includes one or more trigger conditions, one of which may correspond to one of the triggers for WiFi roaming.
In one case, each trigger condition in the roaming preset trigger configuration is default in the disabling state, and the trigger condition that is effective in the current scenario needs to be enabled in S130.
In one case, each trigger condition in the roaming preset trigger configuration is in an enabled state by default, and the trigger condition that is not effective in the current scenario needs to be disabled in S130.
In still another case, some defaults are in an enabled state and some defaults are in a disabled state, and then in S130, the trigger condition that is currently in an enabled state and does not need to be validated is disabled, and/or the trigger condition that is currently in a disabled state and needs to be validated is enabled. In this case, the trigger condition that is in the enabled state by default may be one or more trigger conditions that determine that the frequency of effectiveness is highest based on the statistical characteristics.
In one embodiment, the roaming preset trigger configuration includes:
A trigger condition for triggering WiFi roaming based on signal strength, which is enabled by default;
default enabled station kick mode triggered trigger conditions for WiFi roaming;
default enabled trigger conditions for WiFi roaming triggered based on beacon frame loss rate;
default to the triggering condition of the packet error rate triggered WiFi roaming that is enabled.
As shown in fig. 5, the flow for triggering WiFi roaming based on signal strength may include:
acquiring signal strength (RSSI) of WiFi signal of WiFi AP currently accessed by mobile terminal
Determining whether the RSSI is greater than a first signal strength Threshold (GT); if the RSSI is greater than the GT, wiFi roaming is not performed;
determining whether the RSSI is greater than a second signal strength Threshold (PT) and less than a first signal strength Threshold; PT herein may be less than or equal to GT.
If the RSSI is larger than PT and smaller than GT, entering a tracking stage;
determining whether the RSSI continues to drop by D1 in the tracking stage; if the RSSI continues to drop by D1 in the tracking stage, triggering WiFi roaming;
if the RSSI is directly smaller than the PT, the tracking stage is also entered, whether the RSSI continues to drop D2 is determined in the tracking stage, and if the RSSI continues to drop D2 in the tracking stage, the WiFi roaming is triggered.
Here D1 may be equal to or greater than D2.
The GT and PT herein are signal strength thresholds in WiFi roaming triggered based on signal strength.
As shown in fig. 6, trigger conditions for WiFi roaming, which may be default enabled based on beacon frame loss rate triggering, may include:
if the number of the lost beacon frames is more than 50, entering a tracking stage; here 50 is a first number threshold of beacon frame losses in a trigger condition of WiFi roaming based on a beacon frame loss rate trigger;
after entering the tracking phase, continuing to monitor the number of lost beacon frames;
if the number of the lost beacon frames is greater than 100, executing roaming triggering; here 100 is a second number threshold for beacon frame loss in trigger conditions based on WiFi roaming triggered by beacon frame loss rate; the second number threshold is greater than the first number threshold.
In some specific cases, the mobile terminal may actively transmit probe request frames and receive probe response frames from the WiFi AP even without triggering WiFi roaming.
Before the tracking stage is not entered, the mobile terminal can detect RSSI or count lost beacon frames on hardware without reporting the application layer; if the tracking stage is determined to be entered, the RSSI detection and the number of lost beacon frames on the hardware are reported to an application layer; after the application layer receives the data reported by the hardware, it further judges whether the roaming needs to be started.
Triggering WiFi roaming based on trigger conditions for site kick-off mode triggered WiFi roaming may include:
based on the response mechanism, communication between the station and the AP is carried out, and if the sent data does not receive the response, roaming is triggered; or when no response is received after the response is not received based on a Retry (Retry) mechanism, roaming is triggered.
Triggering conditions for WiFi roaming based on packet error rate triggering the WiFi roaming may include:
and counting the error rate of the Packet (Packet), and triggering WiFi roaming if the error rate reaches an error rate threshold.
In some embodiments, the S130 may include:
and modifying the configuration parameters of the enabled triggering conditions according to the usage scene.
For example, a trigger threshold in one or more trigger conditions is modified. The trigger threshold includes, but is not limited to: a signal strength threshold, a beacon frame loss number threshold, and/or a trigger threshold for packet error rate. Of course, this is merely an example, and the embodiments are not limited thereto.
In one embodiment, the S130 may include:
the second determining module is configured to enable a signal strength-based trigger condition in the roaming preset trigger configuration and improve a signal strength threshold for triggering WiFi roaming of the mobile terminal in the signal strength-based trigger condition in response to an application place of the geographic location where the mobile terminal is located being a home place; and/or, responding to the application place of the geographic position of the mobile terminal as a house place, enabling the triggering condition of WiFi roaming triggered based on the beacon frame loss rate, and reducing the threshold value of the number of lost beacon frames of the triggering condition of WiFi roaming triggered based on the beacon frame loss rate.
The house is corresponding to the home environment, and a plurality of WiFi APs are arranged; the distance of bedrooms, living rooms or restaurants is very close, and the roaming switching of a plurality of WiFi APs with a smaller distance is more suitable for triggering WiFi roaming based on signal strength (RSSI) and triggering other modes such as beacon frame loss.
Thus, at home, a signal strength based trigger condition in a preset trigger configuration for roaming is enabled. And considering that the distance may be short, if the signal intensity threshold in the pre-trigger condition is adopted, the signal intensity threshold for triggering the WiFi roaming may need to be improved, so that the mobile terminal can be re-accessed to the WiFi AP set in the current space after the mobile terminal is in different spaces and can pass through the WiFi roaming, and better WiFi communication quality is obtained.
If the triggering condition of WiFi roaming triggered based on the beacon frame loss rate is a WiFi roaming strategy effective in a home scene, the threshold value of the number of the lost beacon frames can be properly reduced.
In some embodiments, the S130 may include: and responding to the application place being an office place, and determining that the triggering condition of the mobile terminal for WiFi roaming is defined in the preset triggering configuration of the roaming.
That is, in one embodiment, considering that the office location is the location where the average user stays the longest for the daytime period, setting the trigger condition of WiFi roaming at the office location directly to the trigger condition currently enabled in the preset trigger configuration of roaming may at least reduce the rate of update of the WiFi roaming policy when entering and leaving the office location.
In one embodiment, the S130 may further include: and enabling a triggering condition of the WiFi roaming triggered by the packet error rate in the preset triggering configuration of the roaming in response to the application place being a public transportation place.
Public transportation locations herein include, but are not limited to:
airport, high-speed rail station, railway station or subway station, etc.
In these public transportation places, there are situations that the space range is large, the interference ratio is large, and the number of surrounding stations is variable, so in order to prompt the mobile terminal to perform WiFi roaming at a higher frequency, before the WiFi communication needs to be used, the available WiFi AP is found in time and accessed to the corresponding WiFi AP.
In the embodiment of the present disclosure, in response to the application location being a public transportation location, each trigger condition in the roaming preset trigger configuration is enabled, so when the trigger condition defined by any one trigger condition is reached, the mobile terminal is triggered to perform WiFi roaming, so as to find or access a WiFi AP available for access as far as possible.
In some embodiments, the application sites where the mobile terminal is located may include other sites in addition to the above-mentioned home sites, office sites, public transportation sites. In an embodiment of the disclosure, the method further comprises: if the mobile terminal determines that the application place of the current geographic position is uncertain or does not belong to any preset application place, the preset trigger condition can be validated by default.
As shown in fig. 7, an embodiment of the present disclosure provides a triggering condition determining apparatus for WiFi roaming, which is applied to a mobile terminal, and the method includes:
the positioning module 710 is configured to position the mobile terminal to obtain positioning information;
