Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and a system for adjusting a router signal.
Background
With the continuous popularization of communication technology, the use of routers is more and more extensive, and people pay more and more attention to the improvement of the network speed of terminal equipment, wherein the network speed is generally related to the signal strength transmitted by the routers.
More and more routers are currently using Beamforming (Beamforming) to improve the strength of signals transmitted by the routers, and the Beamforming technology is a combination of antenna technology and digital signal processing technology, and is used for directional signal transmission or reception. Beamforming, not a new terminology, is a classical conventional antenna technique. In the early 60 s of the last century, an array signal processing technology adopting antenna diversity reception has received great attention in communication equipment such as electronic countermeasure, phased array radar, sonar and the like. The self-adaptive array interference zero setting technology based on Digital Beam Forming (DBF) can improve the anti-interference capability of a radar system, and is a key technology necessary for a new generation of military radar. The antenna can intelligently improve the radiation of the direction of the user terminal according to the direction of the user terminal, so that the signal intensity received by the user terminal is improved, and the user experience is improved.
However, there are some problems that the total power sent by the router is constant, and the signal strength in one direction is increased while the signal strength in other directions is necessarily reduced. When a plurality of user terminals are used in different directions simultaneously, the router can equally transmit stronger signal power to the directions. But this also causes problems. For example, the user may wish to preferentially increase the signal strength of his device rather than that of the visitor, or increase the received signal strength of the mobile phone rather than that of other terminals such as a notebook.
For example, patent publication No. CN200880114779.2 provides a wireless communication network that uses a beamforming process to improve signal quality and transmission capability and reduce interference. An improved golay sequence is also used in the wireless communication network. In one aspect, the procedure may be used for communication regardless of whether the system is in OFDM mode or single carrier mode. The method improves the signal quality of a user to a certain extent and can reduce the interference problem in the communication process, but when a plurality of user terminals in different directions exist simultaneously, the power in each direction is roughly equally divided, and the flexible change of the signal intensity in a plurality of directions when the user needs to improve or reduce the signal intensity of a certain terminal cannot be met.

Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
Example one
The present embodiment provides a method for adjusting a router signal, as shown in fig. 1, including the steps of:
s11, judging whether a plurality of terminals are connected or not;
s12, if a plurality of terminals are connected, judging whether the beam forming function priority of each terminal is configured;
and S13, if the beam forming function priority of each terminal is configured, distributing the signal intensity of the corresponding level to the direction of the terminal according to the beam forming function priority.
Beamforming (Beamforming) is a combination of antenna technology and digital signal processing technology, intended for directional signal transmission or reception. The existing router utilizes a Beamforming function to improve the received signal strength of the user terminal, but the total power sent by the router is constant, and when a plurality of user terminals are used in different directions simultaneously, the router can equally distribute the signal power for transmitting the same signal strength to the directions.
The method provided by the embodiment can meet the requirement of flexibly adjusting the received signal strength of each terminal by setting the priority of the beam forming function. The Beamforming (Beamforming) function is configured to increase the received signal strength of the corresponding terminal according to the priority level, and the higher the priority level, the higher the received signal strength of the terminal.
Step S11: it is judged whether or not a plurality of terminals are connected, and when a plurality of terminals are connected to the router, the process proceeds to step S12.
And S12, judging whether the beam forming function priority of each terminal is configured, and when a user wants to preferentially improve the signal intensity of own equipment instead of the signal intensity of a visitor or improve the received signal intensity of a mobile phone instead of the signal intensity of other terminals such as a notebook computer and the like, the user can configure the beam forming (Beamforming) function priority on a router system page aiming at different terminals.
Specifically, when a plurality of terminals are connected to the router, the router displays the terminal Name and the corresponding MAC addresses, and the user can freely configure different priorities for different terminals according to the terminal names and the corresponding MAC addresses, or configure the same priority for the plurality of terminals. For example, a first priority terminal, a second priority terminal, a third priority terminal, or the first priority terminal, the second priority terminal, and the like are set. If the user configures the Beamforming (Beamforming) function priority of each terminal in the router, the process proceeds to step S13.
And S13, distributing the signal intensity of the corresponding grade to the direction of the terminal according to the priority of the beam forming function. For example, three terminals are connected, and a first priority, a second priority and a third priority are respectively set for the three terminals, the router system allocates a first signal strength to the direction of the first priority terminal according to the priority of the beam forming function, allocates a second signal strength to the direction of the second priority terminal, and so on. For example, if the user wants to preferentially increase the signal strength of the mobile phone, a first priority may be configured for the mobile phone, and the router system allocates the strongest signal strength to the direction in which the mobile phone is located according to the first priority, where the signal strength received by the mobile phone is the highest. The method and the device are used for solving the problem that the prior art cannot meet the real requirements of users by transmitting the same signal power to the directions of a plurality of terminals when the beam forming (Beamforming) function is utilized to improve the signal strength received by the terminals.
Specifically, the method further comprises the following steps:
establishing a priority table based on the beam forming function priority of each terminal;
and sending signals with different levels of signal strength to corresponding terminals according to the priority table.
The router automatically establishes a priority table after receiving the beam forming function priority configured by the user for the terminal, and arranges in the priority table in sequence according to the priority level of each terminal, as shown in the following table:
| terminal 1 | First priority |
| Terminal 2 | Second priority |
| Terminal 3 | Third priority |
| Terminal 4 | Fourth priority |
| … | … |
The router sends signals with different levels of signal strength to corresponding terminals according to the priority table, for example, a signal with first priority signal strength is sent to the terminal 1, a signal with second priority signal strength is sent to the terminal, and so on. The advantage of establishing the priority table is that the router can conveniently and quickly find the corresponding priority of each terminal and send the signal with the corresponding level signal strength to the corresponding terminal.
Specifically, the method further comprises the following steps:
judging whether a new terminal is connected or not;
if a new terminal is connected, judging whether the priority table is configured with the beam forming function priority of the terminal;
if the beamforming function priority of the terminal is not configured, the terminal is defaulted to be the beamforming function intermediate priority;
updating the priority table again;
and allocating the signal intensity of the corresponding grade to the direction of the terminal again according to the updated priority table.
The router is not fixedly connected with a certain terminal or a plurality of terminals, the terminal can be disconnected with the router or be connected after disconnection, and the router can also be connected with one or more new terminals.
As shown in fig. 5, it is determined whether to connect a new terminal, and when the router sends signals of different grades to a plurality of terminals that have been connected according to the priority table, it is determined whether to access the new terminal or to disconnect and reconnect the terminal if the new terminal is not connected, and if the new terminal is connected, the process of sending the signal to the terminal by the router is not affected; if a new terminal is connected, judging whether the priority table is configured with the beamforming function priority of the terminal, if the user does not configure the priority for the terminal, defaulting to be the intermediate priority and updating the priority table again, for example, a router is connected with 4 terminals before the new terminal is added, wherein the priority is respectively a first priority and a second priority 8230, and if the priority is a fourth priority, the newly added terminal is a third priority; if the user configures the priority for the terminal, the priority table is updated again, for example, the new terminal is the third priority, and the updated priority table is:
| terminal 1 | First priority |
| Terminal 2 | Second priority |
| New terminal | Third priority |
| Terminal 3 | Fourth priority |
| Terminal 4 | Fifth priority |
Specifically, the method further comprises the following steps:
judging whether a reset signal is received or not;
if the reset signal is received, judging whether the beam forming function priority of the terminal is reset or not;
if the beam forming function priority of the terminal is reset, updating the priority table again;
and re-allocating the signal strength of the corresponding grade to the direction of the terminal according to the updated priority table.
When a user uses a plurality of terminals, it is not always necessary for a terminal to receive the strongest signal, for example, the user wants a computer to receive the strongest signal while working, but wants a mobile phone to receive the strongest signal in life, and in order to meet the requirement of the user for flexibly adjusting the strength of the signal received by the terminal, the embodiment provides a way for adjusting the strength of the signal received by the user by changing the terminal, but is not limited to this way.
Specifically, when a user wants to adjust the signal strength received by a terminal, a reset button is pressed, the router receives a reset signal and then displays the beamforming function priority of each terminal, the beamforming function priority of the user is reset, the user can reset the priority of one terminal or simultaneously reset the priorities of a plurality of terminals, and the router renews the priority table according to the reset result and distributes the signal strength of the corresponding level to the direction of the terminal according to the updated priority table.
Accordingly, embodiments of the present disclosure also provide a system for adjusting router signals, as shown in fig. 2, including:
a first judging module 11, configured to judge whether a plurality of terminals are connected;
a second judging module 12, configured to judge whether a beam forming function priority of each terminal is configured;
and the first signal intensity distribution module 13 is configured to distribute signal intensities of corresponding levels to the direction in which the terminal is located.

a second updating module for updating the priority table again;
and the third signal distributing module is used for distributing the signal intensity of the corresponding grade to the direction of the terminal again.

S24, judging whether a reset signal is received or not;
and S25, if a reset signal is received, releasing the priority of the beam forming function.
Unlike the first embodiment, the present embodiment further includes steps S24 and S25.
In order to facilitate the user to flexibly use the function of beamforming priority, this embodiment further provides a step of turning off the priority, and when the user does not need to adjust the signal strength of the signals received by the multiple terminals, the reset key of the router may be pressed to turn off the function of priority. After the priority of the Beamforming function is turned off, the router transmits signals with equal signal strength to the terminals in different directions by using Beamforming (Beamforming). Specifically, whether a reset key pressed by a user is received or not is judged, and if a reset signal is received, the priority of the beam forming function is relieved; if the reset signal is not received, distributing signal intensity of different grades to the direction of each terminal according to the relevant steps.
