DETAILED DESCRIPTION
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise specified. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of devices and methods consistent with some aspects related to the invention as recited in the appended claims.
In the present disclosure, unless otherwise specified, transmission power refers to the transmission power of a gateway device while providing a wireless network, which corresponds to a signal intensity of a signal received by an electronic device. The gateway device may be a router or a switch.
FIG. 1 is a flow chart of an exemplary method 100 for adjusting transmission power consistent with embodiments of the present disclosure. The method 100 can be implemented in, for example, a gateway device. As shown in FIG. 1, at 102, an access device identity is acquired. At 104, a predetermined wireless transmission power corresponding to the access device identity is acquired. Each access device identity corresponds to one predetermined wireless transmission power. At 106, a current transmission power is adjusted according to the predetermined wireless transmission power.
FIG. 2A is a flow chart of another exemplary method 200 for adjusting transmission power consistent with embodiments of the present disclosure. The method 200 can be implemented in, for example, a router.
As shown in FIG. 2A, at 201, the router receives a first setting signal, which is configured to set a wireless transmission power corresponding to an access device identity.
For instance, a user can log in and manage the router through a webpage or a mobile client. The user sends the first setting signal to the router through the webpage or the mobile client. For example, the first setting signal is configured to set the wireless transmission power, that corresponds to a mobile phone associated with an access device identity A, to be a.
As another example, the router provides five optional wireless transmission power levels in advance, which are shown in Table 1.

The user may select a corresponding wireless transmission power level for the access device according to the scenario in which the access device is used. The wireless transmission power corresponding to the selected wireless transmission power level is used as the wireless transmission power corresponding to the access device.
At 202, the router saves the access device identity and the set predetermined wireless transmission power corresponding to the access device identity according to the first setting signal. For example, as shown in Table 2, the router saves the access device identity i.e., Mobile Phone A and the set predetermined wireless transmission power a corresponding to the access device identity, Mobile Phone A according to the first setting signal. One example is shown in Table 2.

At 203, when an electronic device is connected to a wireless network of the router, the router acquires an access device identity of the electronic device. The access device identity may be an MAC address of the access device.
In some embodiments, each time an access device is successfully connected to the wireless network, the router acquires the access device identity of each access device that has been connected to the wireless network.
In some embodiments, the router acquires the access device identity of each access device that has been connected to the wireless network after every predetermined time interval. The predetermined time interval may be preset in the router, or be set by the user according to use conditions.
At 204, the router acquires a predetermined wireless transmission power corresponding to the access device identity. According to the present disclosure, different access device identities may correspond to the same predetermined wireless transmission power or different predetermined wireless transmission powers.
For example, the access device is Mobile Phone A. The router acquires the predetermined wireless transmission power corresponding to Mobile Phone A by, for example, an inquiry of Table 2. According to Table 2, the predetermined wireless transmission power corresponding to Mobile Phone A is a mW.
At 205, the router adjusts a current transmission power of the router according to the acquired predetermined wireless transmission power. The router may adjust the current transmission power directly according to the acquired predetermined wireless transmission power. Alternatively, the router may check with the user and adjust the current transmission power according to feedback from the user.
To check with the user, the router sends an adjustment request to the access device corresponding to the access device identity or an administrator device. The administrator device is, for example, a particular terminal preset by the user. The access device or the administrator device returns an adjustment response according to the adjustment request.
For instance, as shown in FIG. 2B, Mobile Phone A receives an adjustment request 21 sent by the router, and displays the adjustment request 21 in an interface 20 of Mobile Phone A. If the user taps a “Cancel” button 22, the adjustment is denied. If the user taps a “Confirm” button 23, the adjustment is allowed.
When receiving the adjustment response indicating that the adjustment is allowed, the router adjusts the current transmission power to the predetermined wireless transmission power. The signal intensity shown on the access device is adjusted accordingly. For instance, as shown in FIG. 2C, a signal intensity 24 displayed in the interface 20 of Mobile Phone A is adjusted to a.
FIG. 3 is a flow chart of another exemplary method 300 for adjusting transmission power consistent with embodiments of the present disclosure. The method 300 can be implemented in, for example, a router.
As shown in FIG. 3, at 301, the router receives a first setting signal. 301 in the method 300 is similar to 201 in the method 200, and thus detailed description thereof is omitted here.
In some embodiments, there are two or more access devices, such as Mobile Phone A, Tablet B, Access Device 001, Access Device 002, and Access Device 003. The user may set, in the first signal, a wireless transmission power corresponding to Mobile Phone A as a, a wireless transmission power corresponding to Tablet B as b, a wireless transmission power corresponding to Access Device 001 as c, a wireless transmission power corresponding to Access Device 002 as d, and a wireless transmission power corresponding to Access Device 003 as e.
At 302, the router saves the access device identity and the set predetermined wireless transmission power corresponding to the access device identity according to the first setting signal.
For instance, according to the first setting signal, the router saves Mobile Phone A and the corresponding predetermined wireless transmission power a, saves Tablet B and the corresponding predetermined wireless transmission power b, saves Access Device 001 and the corresponding predetermined wireless transmission power c, saves Access Device 002 and the corresponding predetermined wireless transmission power d, and saves Access Device 003 and the corresponding predetermined wireless transmission power e, as shown in Table 3 below.

At 303, the router receives a second setting signal, which is configured to set priorities to the access device identities, as shown in Table 4 below.










TABLE 4

Tablet B
Highest



Access Device 001

At 304, the router saves the access device identities and the corresponding priorities according to the second setting signal.
At 305, when an electronic device is connected to a wireless network of the router, the router acquires an access device identity of the electronic device. 305 in the method 300 is similar to 203 in the method 200, and thus detailed description thereof is omitted here.
At 306, the router acquires the predetermined wireless transmission power corresponding to the access device identity.
In some embodiments, when there are two or more access device identities, the router inquires a priority corresponding to each access device identity. For example, five access devices are simultaneously connected to the router through the wireless network. Table 5 shows the access device identities, and the predetermined wireless transmission power and priority corresponding to each access device identity.

The router then acquires the access device identity having the highest priority, and acquires the predetermined wireless transmission power corresponding to the access device identity having the highest priority. For example, as shown in Table 5, the router acquires the predetermined wireless transmission power b corresponding to the access device having the highest priority, i.e., Tablet B.
At 307, the router adjusts the current transmission power according to the predetermined wireless transmission power. The router may adjust the current transmission power directly according to the acquired predetermined wireless transmission power. Alternatively, the router may check with the user and adjust the current transmission power according to the feedback of the user.
To check with the user, the router sends an adjustment request to the access device corresponding to, for example, the access device identity having the highest priority, or an administrator device. The administrator device is, for example, a particular terminal preset by the user. The access device or the administrator device returns an adjustment response according to the adjustment request.
For instance, after Tablet B receives the adjustment request sent by the router, a prompt window is displayed in an interface of Tablet B. If the user taps a “Cancel” button, the adjustment is denied. If the user taps a “Confirm” button, the adjustment is allowed.
When receiving the adjustment response indicating that the adjustment is allowed, the router adjusts the current transmission power to the predetermined wireless transmission power. For instance, when the adjustment response sent by Tablet B indicates that the adjustment is allowed, the router adjusts the current transmission power to the predetermined wireless transmission power. In some embodiments, if the current transmission power of the router and the inquired predetermined wireless transmission power are the same, then the router does not need to adjust the current transmission power.
FIG. 4 is a flow chart of another exemplary method 400 for adjusting transmission power consistent with embodiments of the present disclosure. The method 400 can be implemented in, for example, a router.
As shown in FIG. 4, at 401, the router receives a first setting signal. 401 in the method 400 is similar to 201 in the method 200, and thus detailed description thereof is omitted here.
In some embodiments, there are two or more access devices, such as Mobile Phone A, Tablet B, Computer F, and Network TV G. The user may set, in the first signal, a wireless transmission power corresponding to Mobile Phone A as a, a wireless transmission power corresponding to Tablet B as b, a wireless transmission power corresponding to Computer F as f, and a wireless transmission power corresponding to Network TV G as g.
At 402, the router saves the access device identity and the set predetermined wireless transmission power corresponding to the access device identity according to the first setting signal.
For example, according to the first setting signal, the router saves Mobile Phone A and the corresponding predetermined wireless transmission power a, saves Tablet B and the corresponding predetermined wireless transmission power b, saves Computer F and the corresponding predetermined wireless transmission power f, and saves Network TV G and the corresponding predetermined wireless transmission power g, as shown in Table 6 below.

At 403, the router receives a third setting signal, which is configured to set priorities to the access device identities within target time periods, as shown in Table 7 below.










TABLE 7

As shown in Table 7, the priorities of the access device identities in different time periods are different. For example, during the daytime (8:00-20:00), the child needs to use Tablet B to view education programs, the father needs to use the computer to view stocks, and the mother only needs to use Mobile Phone A to browse news. Therefore, during this time period, the priority corresponding to Tablet B is the highest, the priority corresponding to Computer F is higher, and the priority corresponding to Mobile Phone A is the lowest. As another example, during the evening time (0:00-8:00/20:00-24:00), the parents want to watch TV using Network TV G and the child needs to use Tablet B to play games. Therefore, during this period, the priority corresponding to Network TV G is the highest, and the priority corresponding to Tablet B is the lowest.
At 404, the router generates priority correspondence relationships corresponding to target time periods according to the third setting signal. The priority correspondence relationships include the access device identities and the set priorities corresponding to the access device identities, such as, for example, shown in Table 7.
At 405, when an electronic device is connected to a wireless network of the router, the router acquires the access device identity of this device. 405 in the method 400 is similar to 203 in the method 200, and thus detailed description thereof is omitted here.
At 406, the router acquires the predetermined wireless transmission power corresponding to the access device identity.
In some embodiments, when there are two or more access device identities, the router inquires a priority corresponding to each access device identity. More particularly, the router acquires a current time, acquires the priority correspondence relationship corresponding to the current time, and inquires the priority corresponding to each access device identity according to the priority correspondence relationship corresponding to the current time.
Then, the router acquires the predetermined wireless transmission power corresponding to the access device identity having the highest priority. More particularly, the router acquires the access device identity having the highest priority level from the access devices that are currently connected to the router, and acquires the predetermined wireless transmission power corresponding to the access device identity having the highest priority.
For example, four access devices are connected to the router. By referring to, for example, Tables 6 and 7, the router acquires the predetermined wireless transmission power b corresponding to Tablet B having the highest priority in the morning, and acquires the predetermined wireless transmission power g corresponding to the access device identity of Network TV G having the highest priority level in the evening.
At 407, the router adjusts the current transmission power according to the predetermined wireless transmission power. 407 in the method 400 is similar to 307 in the method 300, and thus detailed description thereof is omitted here.
