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 transmission power control method according to an embodiment of the present invention, where the transmission power control method 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.

The determining of the motion trajectory of the mobile terminal in the preset time period may be that the mobile terminal predicts the motion trajectory of the mobile terminal in the preset time period according to the motion acceleration and the motion direction, and may also be determined according to the motion trajectory during the historical access to the wireless local area network, which is not limited herein, and 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.

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 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 in the second reference area in the motion position set constituting the motion trajectory, or may be a partial position in the second reference area in the motion position set, which is not limited herein.

S103, the mobile terminal updates the transmitting power of the mobile terminal according to the distance between the at least one motion position and the central point of the second reference area, wherein the updated transmitting power is smaller than the transmitting power 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;

as shown in fig. 1B, when the mobile terminal is transferred from the first reference area to the second reference area of the wireless local area network, the position of the mobile terminal 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 the transmission power of the edge position is the position with the largest transmission power in the second reference area.

In one possible example, the at least one motion position is in a direct proportional relationship with the distance from the center point of the second reference area and the transmission power of the mobile terminal.

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, the transmission power of the mobile terminal at the first motion position is set to be smaller than the transmission power 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 stronger the signal of the wireless local area network is, and the better the signal of the wireless local area network can be received at the smaller transmission power.

Therefore, in this example, the mobile terminal updates the transmission power of the mobile terminal according to the distance between the motion position and the central point of the second reference area, and the smaller the distance, the smaller the transmission power is, which is beneficial to reducing the power consumption of the mobile terminal while ensuring effective reception of the wireless local area network signal.

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, 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, the wireless local area network is used as a query identifier, and a plurality of historical motion tracks matched with the wireless local area network in a historical record are queried;

and determining the motion trail of the mobile terminal in the plurality of historical motion trails within a preset time period according to the current time node.

The history record comprises second reference areas of a plurality of wireless local area networks which are successfully accessed by the mobile terminal and a plurality of motion tracks after the mobile terminal is accessed to the wireless local area networks.

And the determined motion trail of the mobile terminal in the preset time period is a motion trail matched with the current time node and the wireless local area network in the historical record.

The matching with the current time node comprises two conditions that the current time node is consistent with the current time node or the time difference with the current time node is smaller than the preset time difference.

Wherein the motion trajectory may be intermittent, including trajectories when moving and when stationary within a preset time period.

For example, the wireless local area network is a wireless local area network of a user company, and a user enters the company every day in a fixed time period, so that the motion trajectory in the preset time period can be determined to be the motion trajectory of the user after entering the company in the fixed time period.

Therefore, in this example, the mobile terminal determines the motion track matched with the current time node of the wireless local area network according to the history record without detecting and acquiring according to various sensors of the mobile terminal, which is beneficial to reducing the power consumption of the mobile terminal and improving the convenience and speed of determining the motion track.

In this 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 the 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:

determining the position of the mobile terminal with the stay time length longer than the preset time length in the position set forming the motion trail according to the historical record;

and determining the position in the second reference area in the position where the stay time of the mobile terminal is longer than the preset time as the at least one motion position.

The mobile terminal comprises a first reference area, a second reference area, a mobile terminal power consumption detection area, a first position and a second position, wherein the motion trail comprises a plurality of positions located in the second reference area, if the transmitting power of the mobile terminal is changed at all positions located in the second reference area, the complexity of the work of the mobile terminal is increased, and the purpose of reducing the power consumption of the mobile terminal cannot be achieved.

For example, the movement track in the preset time period is a movement track of a user after the user accesses a company wireless local area network in a fixed time period, the user can enter the position of the user for working after entering the company, the stay time at the position of the user is long, and the position can be determined according to a historical record because the user often stays at the position, so that the position is determined to be the movement position in the at least one movement position.

Therefore, in this example, the mobile terminal determines the motion positions with longer dwell time in the motion trajectory according to the history record, and the positions are the at least one motion position, and the mobile terminal changes the transmission power only at the motion positions, 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 transmission power of the mobile terminal according to the distance between the at least one motion position and the center point of the second reference area includes:

determining the target transmitting power 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;

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 transmitting power of the mobile terminal according to the target transmitting power corresponding to the at least one motion position.

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

In this possible example, the determining the target transmission power 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 includes:

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 a mapping relation between a pre-stored distance interval and the transmitting power by taking the distance interval as an inquiry identifier, and determining the transmitting power corresponding to the distance interval as the target transmitting power of the at least one motion position.

The mobile terminal prestores a mapping relation between a distance interval and transmission power, for example, 5m-8m corresponds to first transmission power, 8m-12m corresponds to second transmission power, 7m belongs to the distance interval of 5m-8m, 10m belongs to the distance interval of 8m-12m, each distance interval corresponds to one transmission power, and not each distance corresponds to one transmission power.

Therefore, in this example, the mobile terminal determines the transmission power corresponding to the distance according to the distance interval to which the distance belongs, so that one group of distance parameters corresponds to one transmission power, instead of one distance parameter corresponding to one transmission power, which is beneficial to improving the stability of the transmission power of the mobile terminal and improving the convenience of the transmission power control.

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

s201, when a mobile terminal accesses a wireless local area network, judging whether the signal intensity of the wireless local area network is smaller than a preset threshold value;

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 the transmission power of the mobile terminal to a first transmission power, where the first distance is smaller than the radius of the second reference area, and the first transmission power is smaller than the transmission power 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 transmitting power of the mobile terminal 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 transmitting power is, so that the power consumption of the mobile terminal is reduced while the wireless local area network signal is effectively received.

Referring to fig. 3, fig. 3 is a schematic flow chart of another transmission power control method according to an embodiment of the present invention, consistent with the embodiment shown in fig. 1A, as shown in the figure, the transmission power control method includes:

s301, 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 queries a plurality of historical motion tracks matched with the wireless local area network in a historical record by taking the wireless local area network as a query identifier;

S302, the mobile terminal determines the motion trail of the mobile terminal in a preset time period in the plurality of historical motion trails according to the current time node;

s303, the mobile terminal determines the position of the mobile terminal, of which the stay time is longer than the preset time, in the position set forming the motion trail according to the historical record;

s304, the mobile terminal determines that the position, located in the second reference area, in the position where the stay time of the mobile terminal is longer than the preset time is the at least one motion position;

s305, the mobile terminal determines the distance between the at least one motion position and the center point of the second reference area;

s306, the mobile terminal determines a distance interval to which the distance between the at least one motion position and the center point of the second reference area belongs;

s307, the mobile terminal queries a mapping relation between a pre-stored distance interval and transmitting power by taking the distance interval as a query identifier, and determines the transmitting power corresponding to the distance interval as the target transmitting power of the at least one motion position;

s308, the mobile terminal predicts a time node when the mobile terminal reaches the at least one motion position according to the motion trail;

s309, when the time node of the at least one motion position is reached, the mobile terminal updates the transmitting power of the mobile terminal according to the target transmitting power corresponding to the at least one motion position.

In addition, the mobile terminal determines the motion track matched with the current time node of the wireless local area network according to the historical record without detecting and acquiring according to various sensors of the mobile terminal, so that the electric quantity consumption of the mobile terminal is reduced, the convenience and the speed of determining the motion track are improved, and the motion positions with longer residence time in the motion track are determined according to the historical record, so that the mobile terminal changes the transmitting power only at the motion positions, and the stability of controlling the transmitting power of the mobile terminal is improved.

In addition, the mobile terminal predicts a time node reaching at least one motion position, when the time node is reached, the operation of updating the transmitting power of the mobile terminal is immediately executed, so that the timeliness of updating the transmitting power of the mobile terminal is improved, and the transmitting power corresponding to the distance is determined according to the distance interval to which the distance belongs, so that one group of distance parameters corresponds to one transmitting power instead of one distance parameter, so that the stability of the transmitting power of the mobile terminal is improved, and the convenience of controlling the transmitting power is improved.
