Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The Mobile terminal according to the embodiment of the present invention may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and the like, which have wireless communication functions. For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal. The following describes embodiments of the present invention in detail.

Referring to fig. 1A, fig. 1A is a schematic flow chart of a frequency control method for signal quality detection according to an embodiment of the present invention, where the frequency control method for signal quality detection includes:

s101, when detecting that the mobile terminal is transferred from a first reference area to a second reference area of a wireless local area network, the mobile terminal determines a motion track of the mobile terminal in a preset time period;

the second reference area is an effective coverage area of the wireless local area network relative to the mobile terminal, and the first reference area is an area except the second reference area.

The second reference area may be determined by the mobile terminal according to its own transmission power, or according to the transmission power of the wireless local area network, or may be determined by the mobile terminal according to a history record of accessing the wireless local area network, which is not limited herein.

In one possible example, the determining, when it is detected that the mobile terminal is transferred from a first reference area to a second reference area of the wireless local area network, a motion trajectory of the mobile terminal within a preset time period includes:

when the mobile terminal is detected to be transferred from the first reference area to the second reference area of the wireless local area network, acquiring a reference position of the mobile terminal;

acquiring the motion acceleration and the motion direction of the mobile terminal;

and determining the motion track of the mobile terminal in a preset time period according to the motion acceleration and the motion direction by taking the reference position as an initial position.

The mobile terminal is internally provided with an accelerometer, a gyroscope and a positioning device, the motion acceleration is determined by the accelerometer of the mobile terminal, the motion direction is determined by the gyroscope of the mobile terminal, and the reference position is determined by the positioning device.

The reference position is a position when the mobile terminal detects that the mobile terminal is transferred from the first reference area to the second reference area, the reference position is the reference position parameter, and the reference position parameter comprises a three-dimensional coordinate parameter of the mobile terminal.

The determining of the motion trajectory of the mobile terminal within the preset time period may be that the mobile terminal predicts the motion trajectory of the mobile terminal within a preset time period according to the motion acceleration and the motion direction, where the preset time period may be 5min, 10min, and the like.

For example, when the preset time period is 5min, the mobile terminal predicts a motion trajectory within 5min, and after 5min, the mobile terminal may determine the motion trajectory within the preset time period again by acquiring the position information, the motion acceleration and the motion direction, or the mobile terminal may also acquire the motion acceleration and the motion direction again, and then determine the motion trajectory within the preset time period again by taking the predicted position at 5min as an initial position until the mobile terminal transfers to the first reference area again.

Therefore, in this example, the mobile terminal determines the motion trajectory according to the motion acceleration and the motion direction, and the motion trajectory is a predicted motion trajectory in a preset time period, so that the mobile terminal can acquire the motion trajectory in advance and perform effective post processing, which is beneficial to improving the data processing speed of the mobile terminal.

S102, the mobile terminal determines the distance between at least one motion position located in the second reference area in the motion position set forming the motion track and the center point of the second reference area;

when the second reference area is a circular area, the center point of the second reference area is the center of the circle of the circular area, and when the second reference area is a rectangle, the center point of the second reference area is the intersection point of the diagonals of the rectangular area.

The distance between the at least one motion position located in the second reference area and the center point of the second reference area is a straight-line distance between two points, and the at least one motion position may be the entire position located in the second reference area in the motion position set constituting the motion trajectory, or may be a partial position located in the second reference area in the motion position set, which is not limited herein.

S103, the mobile terminal updates the signal quality detection frequency of the mobile terminal for the wireless local area network according to the distance between the at least one motion position and the central point of the second reference area, wherein the updated signal quality detection frequency is smaller than the signal quality detection frequency of the mobile terminal when the mobile terminal is transferred from the first reference area to the second reference area;

the signal quality detection frequency is a signal quality detection frequency of the wireless local area network, the mobile terminal detects the signal quality of the wireless local area network according to the signal quality detection frequency, the mobile terminal can determine access or interrupt operation for the wireless local area network according to the signal quality of the wireless local area network, and in addition, the closer the mobile terminal is to the central point of the second reference area of the wireless local area network, the stronger the signal strength of the wireless local area network is, the lower the necessity of detecting the signal quality of the wireless local area network is, and therefore, the smaller the signal quality detection frequency can be set.

As shown in fig. 1B, a position of the mobile terminal when the mobile terminal is transferred from the first reference area to the second reference area of the wireless local area network should be an edge position of the second reference area, where the edge position is a position farthest from the central point in the second reference area, so that a signal quality detection frequency of the edge position is a position with a maximum signal quality detection frequency in the second reference area.

In one possible example, the distance between the at least one motion position and the center point of the second reference area is in direct proportion to a signal quality detection frequency of the mobile terminal for the wireless local area network.

For example, the at least one motion position includes a first motion position and a second motion position, and a positional relationship between the first motion position and the second motion position and a central point of the second reference area may be a positional relationship as shown in fig. 1B, where the first motion position is closer to the central point of the second reference area than the second motion position is to the central point of the second reference area, and the signal quality detection frequency of the mobile terminal at the first motion position is set to be smaller than the signal quality detection frequency of the mobile terminal at the second motion position, because the closer the first motion position is to the central point of the second reference area, the better the signal quality of the wireless local area network is, and the higher signal quality detection frequency is not needed.

In this example, the mobile terminal updates the signal quality detection frequency of the mobile terminal for the wireless local area network according to the distance between the motion position and the central point of the second reference area, and the smaller the distance is, the smaller the signal quality detection frequency is, which is beneficial to reducing the power consumption of the mobile terminal while ensuring the higher signal quality of the wireless local area network.

In one possible example, before determining the motion trajectory of the mobile terminal within the preset time period when the mobile terminal is detected to be transferred from the first reference area to the second reference area of the wireless local area network, the method further includes:

when the mobile terminal accesses the wireless local area network, judging whether the signal intensity of the wireless local area network is smaller than a preset threshold value;

when the signal intensity is judged to be smaller than the preset threshold value, acquiring a first position;

when the mobile terminal is interrupted to access the wireless local area network, acquiring a second position;

and determining a second reference area of the wireless local area network by taking the first position as a circle center and the distance between the first position and the second position as a radius.

The preset threshold is dynamic, that is, the preset threshold changes during the process that the mobile terminal continuously accesses the wireless local area network, and the change trend of the preset threshold becomes smaller and smaller, for example, the preset threshold may be-30 dbm, -35dbm, -40 dbm.

For example, when the current signal strength of the wireless local area network is judged to be-35 dbm smaller than the preset threshold value of-30 dbm, determining that the position with the signal strength of-35 dbm is a first position, and updating the preset threshold value to-35 dbm at the same time, in the process that the mobile terminal continuously accesses the wireless local area network, if the position with the signal strength of-40 dbm is detected to be smaller than the updated preset threshold value, updating the first position to be the position with the signal strength of-40 dbm, and updating the preset threshold value to-40 dbm at the same time.

Wherein a distance between the first position and the second position is a linear distance between two points, and the second reference area is a circular area.

The first position is a central point position of the second reference area of the wireless local area network, that is, a position in the second reference area where the signal strength relative to the mobile terminal is strongest.

Wherein the first position and the second position are both position parameters, and the position parameters include three-dimensional coordinate parameters of the positions.

As can be seen, in this example, the mobile terminal determines the second reference area of the wireless local area network relative to the mobile terminal according to the situations that the mobile terminal accesses the wireless local area network and interrupts accessing the wireless local area network, instead of enabling all the mobile terminals to have the same second reference area for the wireless local area network, which is beneficial to improving the accuracy of the mobile terminal in acquiring the second reference area, and the dynamic preset threshold is set, which is beneficial to further improving the accuracy of the second reference area.

In one possible example, after determining a motion trajectory of the mobile terminal within a preset time period when the mobile terminal is detected to be transferred from a first reference area to a second reference area of a wireless local area network, the determining a distance between at least one motion position of the second reference area and a center point of the second reference area in a set of motion positions constituting the motion trajectory further includes:

dividing a motion track positioned in the second reference area in the motion track into a plurality of track segments according to a preset length;

determining a midpoint location of each of the plurality of trajectory segments as the at least one motion location.

The method for dividing, by the mobile terminal, the motion trajectory located in the second reference region in the motion trajectory into a plurality of trajectory segments according to the preset length may be equally dividing according to the preset length, for example, when the motion trajectory does not pass through the center point of the second reference region, the motion trajectory may also be non-equally dividing into a plurality of trajectory segments according to the preset length, for example, when the motion trajectory passes through the center point of the second reference region and the motion trajectory is in a non-equal dividing condition, when the radius of the second reference region is 24m, the preset length is 5n-2, and n is a positive integer, if n is 1, the first range is 0m-3 m; if n is 2, the second range is 3m to 11 m; if n is 3, the third range is 11m-24m, and accordingly, the motion trajectory is divided into two trajectory segments when the motion trajectory is 10m, the first trajectory segment is 0m-3m, the midpoint is the position at 1.5m, the second trajectory segment is 3m-10m, and the end point is the position at 6.5 m.

It can be seen that, in this example, the mobile terminal divides the motion trajectory into a plurality of trajectory segments according to the preset length, and determines that the midpoint position of each trajectory segment is at least one motion position, and the mobile terminal changes the signal quality detection frequency only at the motion positions, instead of changing the signal quality detection frequency of the mobile terminal at all the positions of the motion trajectory, which is beneficial to improving the stability of the control of the transmission power of the mobile terminal.

In one possible example, the updating the signal quality detection frequency of the mobile terminal for the wireless local area network according to the distance between the at least one motion position and the second reference area center point includes:

determining the target signal quality detection frequency of the mobile terminal at the at least one motion position according to the distance between the at least one motion position and the center point of the second reference area;

predicting a time node of the mobile terminal reaching the at least one motion position according to the motion trail;

and when the time node of the at least one motion position is reached, updating the signal quality detection frequency of the mobile terminal aiming at the wireless local area network according to the target signal quality detection frequency corresponding to the at least one motion position.

The specific implementation manner of determining the target signal quality detection frequency of the mobile terminal at the at least one motion position according to the distance between the at least one motion position and the center point of the second reference area may be:

determining a distance interval to which the distance between the at least one motion position and the center point of the second reference area belongs;

and inquiring the mapping relation between the pre-stored distance interval and the signal quality detection frequency by taking the distance interval as an inquiry identifier, and determining the signal quality detection frequency corresponding to the distance interval as the target signal quality detection frequency of the at least one motion position.

The mobile terminal prestores a mapping relationship between a distance interval and a signal quality detection frequency, for example, 5m-8m corresponds to a first signal quality detection frequency, 8m-12m corresponds to a second signal quality detection frequency, 7m belongs to the distance interval of 5m-8m, and 10m belongs to the distance interval of 8m-12m, each distance interval corresponds to a signal quality detection frequency, but not each distance corresponds to a signal quality detection frequency.

It can be seen that, in this example, the mobile terminal predicts a time node when the mobile terminal reaches at least one motion location, and immediately executes an operation of updating the signal quality detection frequency of the mobile terminal when the time node is reached, which is beneficial to improving timeliness of updating the signal quality detection frequency of the mobile terminal, rather than detecting whether the position of the mobile terminal reaches the motion location all the time after determining at least one motion location, which can save system resources for other processing operations of the mobile terminal, and is beneficial to further reducing power consumption of the mobile terminal.

In this possible example, the updating, when the time node of the at least one moving location is reached, a signal quality detection frequency of the mobile terminal for the wireless local area network according to a target signal quality detection frequency corresponding to the at least one moving location includes:

detecting a current location of the mobile terminal when the time node of the at least one motion location is reached;

when the current position is detected to be not matched with the at least one motion position, updating the target signal quality detection frequency of the mobile terminal according to the current position;

and updating the signal quality detection frequency of the mobile terminal aiming at the wireless local area network according to the updated target signal quality detection frequency.

When the time node is reached, the current position of the mobile terminal is detected, whether the current position is matched with the position corresponding to the time node or not is detected, and if not, the target signal quality detection frequency is determined again according to the current position.

The detecting whether the current position is matched with the position corresponding to the time node may be whether the current position is consistent with the position corresponding to the time node, or may be whether a distance difference between the current position and the position corresponding to the time node is smaller than a preset distance.

Therefore, in this example, when the mobile terminal reaches the time node of the signal quality detection frequency change, the current position is detected again, whether the position changes is determined, and the target signal quality detection frequency is updated when the position changes, which is beneficial to improving the accuracy of the signal quality detection frequency control of the mobile terminal.

Referring to fig. 2, fig. 2 is a schematic flow chart of another frequency control method for signal quality detection according to an embodiment of the present invention, consistent with the embodiment shown in fig. 1A, as shown in the figure, the frequency control method for signal quality detection includes:

s202, when the mobile terminal judges that the signal intensity is smaller than the preset threshold value, acquiring a first position;

s203, when the mobile terminal is interrupted to access the wireless local area network, a second position is obtained;

s204, the mobile terminal determines a second reference area of the wireless local area network by taking the first position as a circle center and the distance between the first position and the second position as a radius;

s205, when detecting that the mobile terminal is transferred from a first reference area to a second reference area of the wireless local area network, the mobile terminal determines a motion track of the mobile terminal in a preset time period;

wherein the first reference region is a region other than the second reference region.

S206, the mobile terminal determines the distance between at least one motion position located in the second reference area in the motion position set forming the motion track and the center point of the second reference area;

s207, when the distance between the at least one motion position and the center point of the second reference area is a first distance, the mobile terminal updates a signal quality detection frequency of the mobile terminal for the wireless local area network to be a first signal quality detection frequency, where the first distance is smaller than a radius of the second reference area, and the first signal quality detection frequency is smaller than a signal quality detection frequency of the mobile terminal when the mobile terminal is transferred from the first reference area to the second reference area of the wireless local area network.

In addition, the mobile terminal determines the second reference area of the wireless local area network relative to the mobile terminal according to the conditions of accessing the wireless local area network and interrupting accessing the wireless local area network, instead of enabling all the mobile terminals to have the same second reference area for the wireless local area network, so that the accuracy of acquiring the second reference area by the mobile terminal is improved.

In addition, the mobile terminal updates the signal quality detection frequency of the mobile terminal for the wireless local area network according to the distance between the motion position and the central point of the second reference area, and the smaller the distance is, the smaller the signal quality detection frequency is, so that the power consumption of the mobile terminal is reduced while the higher signal quality of the wireless local area network is ensured.

s304, the mobile terminal divides the motion position of the second reference area in the motion track into a plurality of track segments according to a preset length;

s305, the mobile terminal determines the midpoint position of each track segment in the plurality of track segments as the at least one motion position;

s306, the mobile terminal determines the target signal quality detection frequency of the mobile terminal at the at least one motion position according to the distance between the at least one motion position and the central point of the second reference area;

s307, the mobile terminal predicts a time node of the mobile terminal reaching the at least one motion position according to the motion trail;

s308, when the mobile terminal reaches the time node of the at least one motion position, detecting the current position of the mobile terminal;

s309, when the mobile terminal detects that the current position is not matched with the at least one motion position, updating the target signal quality detection frequency of the mobile terminal according to the current position;

and S310, the mobile terminal updates the signal quality detection frequency of the mobile terminal aiming at the wireless local area network according to the updated target signal quality detection frequency.

In addition, the mobile terminal determines a motion track according to the motion acceleration and the motion direction, and the motion track is a predicted motion track in a preset time period, so that the mobile terminal can acquire the motion track in advance and perform effective post processing, the data processing speed of the mobile terminal is favorably improved, the motion track is divided into a plurality of track sections according to a preset length, at least one motion position is further determined, the mobile terminal only changes the signal quality detection frequency at the motion position, and the stability of the control of the transmission power of the mobile terminal is favorably improved.

In addition, the mobile terminal predicts a time node reaching at least one motion position, immediately executes an operation of updating the signal quality detection frequency of the mobile terminal when the time node is reached, so that timeliness of updating the signal quality detection frequency of the mobile terminal is improved, instead of detecting whether the position of the mobile terminal reaches at least one motion position, power consumption of the mobile terminal is further reduced, when the time node of changing the signal quality detection frequency is reached, the current position is detected again, whether the position changes is determined, and when the position changes, the target signal quality detection frequency is updated, so that accuracy of controlling the signal quality detection frequency of the mobile terminal is improved.
