Description

Method for obtaining antenna combination, electronic device and computer readable storage medium

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a method for obtaining an antenna combination, an electronic device, and a computer-readable storage medium.

Background

With the rapid development of network communication technology, wireless routers are widely applied to work and life scenes by people. The wireless router can provide a wireless fidelity (WIFI) network for the terminal devices within the coverage area, so that the terminal devices which are hung down can access the internet.

Common WIFI networks typically use two frequency bands, 2.4G and 5G, for communication. Due to the characteristics of large bandwidth and high speed, WIFI-5G is the first choice in some high-speed scenes, such as low-delay game scenes or live-broadcast scenes with high-speed requirements. However, compared with WIFI-2.4G, WIFI-5G has a small coverage range due to high frequency and poor diffraction capability and large signal loss in the process of propagation or wall penetration. In order to increase the signal coverage of WIFI-5G, usually in a wireless router, besides setting an omnidirectional antenna, a plurality of directional antennas are also added to increase the coverage of WIFI-5G signals, and the directions of the high-gain beams of each directional antenna are different, so that the coverage of the high-gain beams can be more comprehensive by combining the plurality of directional antennas, and no matter which direction the hanging terminal device is located in the wireless router, the hanging terminal device can be located in the area covered by the high-gain beams of the routing antennas, thereby ensuring the communication quality of WIFI-5G.

However, when the use state of the terminal device changes, for example, the location of the terminal device moves, and the coverage of the signal of the WIFI-5G is weak and normal communication cannot be performed, the network connection between the terminal device and the wireless router may fall back from the WIFI-5G to the WIFI-2.4G. Under the requirement of a high-rate scene of the terminal device, the wireless router can temporarily select a directional antenna different from the last time to reestablish WIFI-5G communication with the terminal device in the next scanning period. However, if the terminal device is not in the sector covered by the high-gain beam of the selected directional antenna at this time, the communication for establishing WIFI-5G may fail, and the network connection may be switched back to WIFI-2.4G. And when the wireless router starts to scan in the next scanning period, the wireless router continues to adopt another directional antenna to try to establish the WIFI-5G communication until the WIFI-5G communication is established successfully or all the directional antennas are patrolled in turn.

However, the wireless router continuously tries to establish the communication of the WIFI-5G by using different directional antennas, which takes a lot of time, and the network connection is continuously switched between the WIFI-5G and the WIFI-2.4G, so that it is impossible to select a proper directional antenna to establish the network connection of the WIFI-5G for communication in time, which affects the user experience.

The first frequency band can be a frequency band of WIFI-2.4G, and the second frequency band can be a frequency band of WIFI-5G. The first network data may be Channel State Information (CSI), (received signal strength indicator, RSSI), a Bit Error Rate (BER), a Packet Error Rate (PER), a communication rate or a delay of WIFI-2.4G. The first location is where the end device is currently located, which is within the signal coverage of the wireless router. A plurality of locations in the mapping library are each located within the signal coverage of the line router. The at least one antenna combination is a combination of antennas that can be used for communication by using signals of the second frequency band, and may include one or more groups. The first data notch is a notch corresponding to the first network data, and may be the network data with the minimum difference from the first network data, or may be a network data range including the first network data, which is not limited herein.

Meanwhile, the method can determine the target antenna combination with good communication quality at one time, and can avoid the problem of network switching failure caused by improper antenna combination selection possibly caused by traversing different antenna combinations, thereby avoiding network interruption and improving user experience.

In some possible implementations, the obtaining of the mapping library includes: when the terminal equipment is located at a first position, acquiring first network data and second network data, wherein the second network data are used for representing a communication state when a second frequency band is adopted for communication through the target antenna combination, and the communication state represented by the second network data meets a preset communication requirement; and determining that the first network data and the target antenna combination have a corresponding relation so as to generate a mapping library.

Optionally, the second network data may be data that meets a preset communication requirement when frequency band communication using WIFI-5G is performed.

In the method, the wireless router can quickly and accurately find the target antenna combination corresponding to the first data gear associated with the first network data in the mapping library by acquiring the first network data, and the target antenna combination meets the preset communication requirement of WIFI-5G, so that the antenna combination acquisition efficiency is higher and more accurate.

In some possible implementation manners, the second network data is a group of network test data in which communication quality meets a preset communication requirement among a plurality of groups of network test data, the plurality of groups of network test data include first network test data, the first network test data is used for representing communication quality when communication is performed in a second frequency band through a first antenna combination in a plurality of antenna combinations, the first antenna combination is any one of the plurality of antenna combinations, and the plurality of groups of network test data and the plurality of antenna combinations correspond to one another.

The wireless router may obtain the second network data meeting the preset communication requirement by traversing all antenna combinations at each typical position, for example, obtaining a set of network test data at the first position by using each antenna combination. For example, at the first position, the first antenna combination in the multiple antenna combinations is used to obtain the first network test data, the second antenna combination may also be used to obtain the second network test data, and so on, so as to obtain multiple sets of network test data. And then comparing the network test data corresponding to all the antenna combinations, and finding out a group of network test data with the communication quality meeting the preset communication requirement. The set of network test data meeting the preset communication requirement can be used as second network data so as to determine the target antenna combination, and the accuracy of the determined target antenna combination is ensured.

In some possible implementation manners, when the preset communication requirement is a requirement of a communication rate, the second network data is a group of network test data representing the highest communication rate in the plurality of groups of network test data; when the preset communication requirement is a delay requirement, the second network data is a group of network test data with the lowest representation delay in the multiple groups of network test data; when the preset communication requirement is the requirement of the bit error rate, the second network data is a group of network test data representing the lowest bit error rate in the multiple groups of network test data; when the preset communication requirement is a requirement of packet loss rate, the second network data is a group of network test data representing the lowest packet loss rate in the multiple groups of network test data; when the preset communication requirement is a requirement of a Received Signal Strength Indicator (RSSI), the second network data is a group of network test data which represents the maximum RSSI in the plurality of groups of network test data.

The wireless router can measure the quality of communication through any one or more of communication indexes such as communication rate, delay, RSSI, packet loss rate and bit error rate, so that the technical scheme of the application has diversified implementation modes and strong flexibility.

In some possible implementation manners, when the terminal device is a non-movable device, the mapping library has a set of corresponding relations associated with the terminal device; when the terminal device is a movable device, the mapping library has a plurality of sets of corresponding relationships associated with the terminal device, each set of corresponding relationships is obtained when the terminal device is located at one of a plurality of positions, and the plurality of positions include the first position.

The mapping library may store a correspondence of one terminal device, and may also store a correspondence of a plurality of terminal devices, where each correspondence is labeled with an identifier of a corresponding terminal device.

For a non-removable device, a set of corresponding relationships can satisfy the use requirement of the non-removable device at a fixed position, so that the data in the mapping library is as compact as possible.

For the movable equipment, compared with one group of relations, the multiple groups of corresponding relations can cover the condition of the movable equipment at multiple different positions in a wider range, so that the acquisition result of the antenna combination of the movable equipment is more accurate, and the communication quality is ensured.

In some possible implementation manners, when the data gear is a network data range, searching in a preset mapping library according to the first network data to obtain a target antenna combination corresponding to the first network data, including: searching in a mapping library according to the first network data to obtain a first network data range in which the first network data is located; and determining antenna combination corresponding to the first network data range in the mapping library as target antenna combination.

The wireless router can obtain the target antenna combination corresponding to the first network data by searching the mapping database through judging the network data range where the first network data is located or comparing the difference between the first network data and the network data in the mapping database, so that the realization mode is flexible.

In some possible implementations, obtaining the first network data includes: when the terminal device is a core device, first network data is acquired, and the core device is a device with a high-gain beam requirement.

The wireless router may also determine whether the connected terminal device is a core device, and if the connected terminal device is a core device, the wireless router indicates that the terminal device is a terminal device with a high-gain beam requirement. The wireless router may determine that a high-rate, low-latency communication channel needs to be established using a second frequency, e.g., WIFI-5G, with the high-gain beam aligned at that time, and initiate the step of acquiring the first network data. If the terminal device is not a core device and does not have a high-gain beam requirement, the communication requirement can be met by using a first frequency band with low frequency, for example, the frequency of WIFI-2.4G, to communicate between the wireless router and the terminal device, so that the step of acquiring first network data is not required, the network connection does not need to be switched, and the system overhead can be saved.

In some possible implementations, obtaining the first network data includes: receiving an antenna switching request from terminal equipment; first network data is acquired in response to an antenna switching request.

The wireless router responds to the antenna switching request sent by the terminal equipment to trigger the process of acquiring the target antenna combination, so that the fixed monitoring period of the wireless router does not need to wait for coming, the waiting time is reduced, the antenna combination is more efficiently acquired, and the user experience is improved.

In some possible implementation manners, the first frequency band is a 2.4G frequency band of WIFI, and the second frequency band is a 5G frequency band of WIFI.

In some possible implementations, the first network data includes channel state information, CSI.

The CSI can describe the attenuation factor of the signal on each transmission path, the carried information of the channel is richer than other communication indexes, the communication system is adjusted according to the CSI to adapt to the current channel condition, and a guarantee is provided for high-reliability and high-speed communication in a multi-antenna system.

In some possible implementations, the method further includes: acquiring third network data, wherein the third network data is used for representing the communication quality when the third network data is communicated with the terminal equipment by using a second frequency band; and if the third network data do not meet the preset communication requirement, updating the mapping library.

During the use of the wireless router, there may be a shift in position or a shift in direction, for example, when a user accidentally touches the wireless router while plugging or unplugging the power supply, or the user actively changes the position of the wireless router. At this time, the mapping library established before may not correctly indicate the required antenna combination, so the corresponding relationship in the mapping library may be updated again to ensure the accuracy of the corresponding relationship, and further ensure the communication quality.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Wherein in the description of the embodiments of the present application, "/" indicates an inclusive meaning, for example, a/B may indicate a or B; "and/or" herein is merely an association relationship describing an associated object, and means that there may be three relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two.

In the following, the terms "first", "second" and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", "third" may explicitly or implicitly include one or more of the features.

With the rapid development of network communication technology, wireless routers are widely applied to work and life scenes by people. The wireless router can provide a WIFI network for the terminal equipment within the coverage range, so that the hung terminal equipment can be accessed to the Internet.

The common WIFI network generally adopts two frequency bands of WIFI-2.4G and WIFI-5G for communication. The WIFI-2.4G has low frequency and strong diffraction capability, and has less signal loss and larger coverage range in the transmission process or wall penetration. The WIFI-5G has higher frequency and cleaner electromagnetic environment, so that the interference in the space is less, and the characteristics of more channels, large bandwidth and high speed are achieved, so that the WIFI-5G becomes a first choice in high-speed scenes, such as game scenes or live network scenes with high-speed requirements. However, compared with WIFI-2.4G, WIFI-5G has a small coverage range due to high frequency, poor diffraction capability and large signal loss in the process of propagation or wall penetration. The WIFI-5G in the application does not refer to the frequency of the frequency point of 5GHz, but comprises the corresponding frequencies of all channels of the WIFI-5G; the WIFI-2.4G does not refer to the frequency of the frequency point of 2.4GHz alone, but refers to the frequency corresponding to all channels including the WIFI-2.4G.

In order to increase the coverage of WIFI-5G signals, a wireless router is usually provided with a plurality of directional antennas in addition to an omnidirectional antenna to increase the coverage of WIFI-5G signals. The omnidirectional antenna is an antenna with uniform gain around the antenna, and the directional antenna is an antenna with high gain in a fixed direction and low gain in other directions. The direction of the high-gain beam of each directional antenna in the wireless router is different, so that the directional coverage of the high-gain beam can be more comprehensive by combining a plurality of directional antennas. Alternatively, the directional antenna in the present application may adopt a dual-polarized antenna including a horizontal polarization and a vertical polarization.

Fig. 1 is a schematic diagram of an example wireless router 100 including a directional antenna and an omni-directional antenna. The wireless router 100 in fig. 1 is illustrated by including four omnidirectional antennas and three directional antennas, and specifically includes: omni-directional antenna 101, omni-directional antenna 102, omni-directional antenna 103, and omni-directional antenna 104, directional antenna 105, directional antenna 106, and directional antenna 107. Generally, the four omnidirectional antennas can be used for transceiving signals of WIFI-2.4G and can also be used for transceiving signals of WIFI-5G. The four omnidirectional antennas and the three directional antennas can be used for transceiving signals of WIFI-5G, and when the three directional antennas are set, high-gain beams of different directional antennas are generally respectively directed to different directions, so that the high-gain beams can cover a range of 360 degrees around the wireless router 100. Therefore, no matter which direction the wireless router 100 hangs down the terminal device 200, the terminal device can be located in the area covered by the high-gain beam of at least one routing antenna, so as to ensure the communication quality of WIFI-5G. Wireless router 100 may freely select which omni-directional antennas and which directional antennas to combine for WIFI-5G communications.

As shown in fig. 2, the respective directional patterns of the directional antenna and the omnidirectional antenna are shown by dotted lines, and the high-gain beam of each directional antenna can cover one sector (the sector area, in fig. 2, the area around the wireless router is divided into sector 1, sector 2, and sector 3 as an example). When the location of terminal device 200 is in sector 2 covered by the high-gain beam of directional antenna 106, wireless router 100 may select omni-directional antenna 103, omni-directional antenna 104, and directional antenna 106 to transceive WIFI-5G signals. When the position of the terminal device 200 changes, the signal of the WIFI-5G may become very weak by using the directional antenna 106, and the network connection between the terminal device 200 and the wireless router 100 may fall back from the WIFI-5G to WIFI-2.4G, so as to ensure continuous connection. However, it is desirable to continue to use WIFI-5G for communication between wireless router 100 and end device 200 based on the requirements of the high rate scenario. Therefore, wireless router 100 may temporarily switch a different directional antenna to re-establish WIFI-5G communication with terminal device 200 at the next scanning cycle, for example, select a combination of omni-directional antenna 103, omni-directional antenna 104, and directional antenna 105 to transceive WIFI-5G signals. However, if the terminal device 200 does not move into the sector 1 covered by the high-gain beam of the directional antenna 105 at this time, and the wireless router 100 selects the combination of the omnidirectional antenna 103, the omnidirectional antenna 104, and the directional antenna 105 to transmit and receive signals of WIFI-5G, the network may be interrupted because the signals are weak and cannot establish communication of WIFI-5G. At this time, the network connection between terminal device 200 and wireless router 100 is switched back to WIFI-2.4G. Then, the wireless router 100 continues to switch to another directional antenna temporarily in the next scanning period, for example, the directional antenna is switched to the directional antenna 107 to attempt to establish the communication of WIFI-5G, and since the terminal device 200 moves right into the sector 3 corresponding to the high-gain beam of the directional antenna 107, the communication of WIFI-5G can be successfully established. In this application, the process of positioning the terminal device 200 in the sector corresponding to the high-gain beam of one directional antenna and selecting the directional antenna to transmit and receive signals is referred to as the process of high-gain beam alignment.

However, the wireless router 100 continuously tries to establish the WIFI-5G communication mode by combining the antennas with different directional antennas, so that the network connection may be continuously switched between the WIFI-5G and the WIFI-2.4G, and a proper directional antenna cannot be selected in time to establish the WIFI-5G network connection for the WIFI-5G communication, which affects the user experience.

In the technical solution provided in the embodiment of the present application, the terminal device may be placed at different positions, and then the wireless router establishes a set of corresponding relationships for each different position, where the corresponding relationships are: and the wireless router and the terminal equipment at the position use the WIFI-2.4G network to communicate, and the wireless router and the terminal equipment at the position use the corresponding relation between the network data and a group of 5G antenna combinations (combination forms of antennas for communication of frequency bands of WIFI-5G) with the best communication quality at the position. It should be noted that the group of antenna combinations with the best communication quality can be obtained by traversing all antenna combinations by the wireless router when the terminal device is located at the position. It should be noted that the antenna combination required to be determined in this application is an antenna combination for WIFI-5G communication. Typically, this position is within the range covered by the high gain beam of the directional antenna in the set of antenna combinations. When the wireless router and the terminal equipment need to use a WIFI-5G network for communication, the wireless router can acquire network data when the wireless router communicates with the terminal equipment at the current position by using the WIFI-2.4G network, and then searches in the pre-established corresponding relation to obtain an antenna combination corresponding to the WIFI-2.4G network data at the position. It can be determined that, compared with other antenna combinations, the antenna combination corresponding to the obtained WIFI-2.4G network data at the current position has the best performance in transceiving WIFI-5G signals. And then, the antenna combination with the best performance is utilized to carry out WIFI-5G communication with the terminal equipment at the position, so that the communication quality of WIFI-5G can be ensured. According to the method, the WIFI-2.4G network data which are easy to obtain are adopted, the WIFI-5G antenna combination with good communication quality can be accurately and quickly found in a table look-up mode, and the antenna switching efficiency is improved.

The method for obtaining the antenna combination provided in the embodiment of the present application may be applied to a router, a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, a super-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and other devices, and may also be applied to the foregoing network devices such as a wireless router, and the embodiment of the present application does not set any limit to specific types of devices.

It is to be understood that the structure of the wireless router 100 illustrated in the embodiment of the present application does not constitute a specific limitation to the network device. In other embodiments of the present application, the wireless router 100 may include more or fewer components than shown, or combine certain components, or split certain components, or a different arrangement of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

For convenience of understanding, the following embodiments of the present application will specifically describe a method for acquiring an antenna combination, which is provided in the embodiments of the present application, by taking a wireless router having a structure shown in fig. 1 as an example, with reference to the accompanying drawings and application scenarios.

First, the process of how to build the mapping library is introduced:

if the terminal device is a non-movable device with a fixed position in the working process, such as a large-screen device (smart television), other routers serving as sub-routes, or a projector used fixedly, the network data of only one fixed position (the position of the terminal device in normal use) can be acquired when the mapping library is established, and a group of corresponding relations are established. When the terminal device is located at the fixed position, the WIFI-2.4G network data are collected, for example, the CSI of the WIFI-2.4G is collected, a group of WIFI-5G antenna combinations with the best communication quality are tested, and the corresponding relation between the WIFI-2.4G network data and the antenna combinations is established.

If the terminal device is a mobile device, such as a smart phone, a tablet computer and the like, which can move in the working process, network data at a plurality of different positions needs to be collected when a mapping library is established, and a corresponding relation between the network data of WIFI-2.4G and the antenna combination of WIFI-5G at the plurality of positions is established.

Of course, the wireless router may also store respective corresponding relationships of the plurality of terminal devices, and the corresponding relationships respectively carry the identifiers of the respective corresponding terminal devices, so as to distinguish the terminal devices in the subsequent search. Optionally, the carried identifier of the terminal device may be a Media Access Control (MAC) address of the terminal device, a name of the terminal device customized by a user, and the like, which is not limited in this embodiment of the present application.

Taking the schematic plan view of the room area shown in fig. 3 as an example, the wireless router 100 is placed at location a, the large screen device 201 is fixedly placed at location B for use, and the smartphone 202 may move throughout the room area.

Generally, after the large-screen device 201 is powered on, it may search for surrounding WIFI signals and send a request to establish a WIFI connection with the wireless router. The wireless router 100 may determine that the large-screen device 201 is a non-removable device according to the request carrying the self-identification sent by the large-screen device 201. When the large-screen device 201 is placed at location B, the wireless router 100 may establish a set of correspondences where the large-screen device 201 is located at location B. For example, for WIFI-5G, the 5G antenna combination that the wireless router can invoke includes three combination forms of antenna combination 1, antenna combination 2, and antenna combination 3, and the directional antenna in antenna combination 1 is directional antenna 105, the directional antenna in antenna combination 2 is directional antenna 106, and the directional antenna in antenna combination 3 is directional antenna 107. Wireless router 100 may obtain 2.4G network data 1 when using a WIFI-2.4G network. Due to the fact that the antennas used by the WIFI-2.4G network are combined into a fixed omnidirectional antenna combination form, there is usually no scheme for switching antennas, and in the coverage area of the WIFI-2.4G network, the 2.4G network data of the same terminal device can represent information of the orientation of the terminal device, such as which direction the terminal device is located in the wireless router, and the distance between the terminal device and the wireless router in the direction.

For example, the 2.4G network data 1 can characterize which position the large screen device 201 is in the wireless router 100, and the distance between the large screen device and the wireless router 100. Then, the wireless router 100 may use the antenna combination 1 to communicate with the large-screen device 201 by using a WIFI-5G network, and obtain corresponding 5G network data 1; then, the antenna combination 2 and the antenna combination 3 are sequentially used to communicate with the large-screen device 201 by using a WIFI-5G network, and 5G network data 2 when the antenna combination 2 is used and 5G network data 3 when the antenna combination 3 is used are obtained (i.e., all WIFI-5G antenna combinations are traversed). Then, the wireless router 100 may compare the 5G network data (i.e., 5G network data 1, 5G network data 2, and 5G network data 3) obtained by different antenna combinations, and find out the 5G network data that characterizes the WIFI-5G communication with the best quality, for example, if the signal of the 5G network data 1 obtained by using the antenna combination 1 is the strongest, it may be determined that the obtained corresponding relationship when the large-screen device 201 is at the position B is: and 2.4G, corresponding relation 1 between the network data 1 and the antenna combination 1, and storing the corresponding relation 1 in a mapping base.

For example, when the wireless router 100 communicates with the large-screen device 201 at the location B, the CSI-1 acquired into the 2.4G network data 1 is an array [ a, B, c, d ], where a, B, c, d respectively correspond to the CSI data of the channel states of the directional antenna 101, the directional antenna 102, the directional antenna 103 and the directional antenna 104, and the CSI data is usually in a complex form and includes a real part and an imaginary part. The wireless router 100 also obtains 5G network data 1, 5G network data 2, and 5G network data 3 corresponding to the antenna combination 1, the antenna combination 2, and the antenna combination 3, which are respectively used at the position B. Taking 5G network data as RSSI as an example, 5G network data 1, 5G network data 2, and 5G network data 3 are-75 dBm, -85dBm, -95dBm, respectively. The RSSI corresponding to each antenna combination is a weighted value of the RSSI corresponding to each antenna in the antenna combination. For example, -75dBm is a weighted value of RSSI for each of the four antennas in antenna combination 1. The weighting method of the weighting value here may be: and adding an average, or taking a maximum value, or weighting unequal ratios, and the like, which are not limited in the embodiment of the application, and can be used for distinguishing the combination characteristics of different antennas. It can be seen that the signal of the 5G network data 1 represented by-75 dBm is strongest, and among the three antenna combinations of the antenna combination 1, the antenna combination 2 and the antenna combination 3, the communication quality is best when the antenna combination 1 corresponding to the 5G network data 1 is used for receiving and transmitting signals of WIFI-5G; and the signal of the 5G network data 3 represented by-95 dBm is the weakest, and the communication quality is the worst when the antenna combination 3 corresponding to the 5G network data 3 is used for transceiving WIFI-5G signals in the three antenna combinations of the antenna combination 1, the antenna combination 2 and the antenna combination 3.

Optionally, the 5G network data may also be data types of BER, PER, communication rate, and delay, and these data types may all represent communication quality of WIFI-5G, which is not limited in this application. The larger the BER is, the worse the communication quality is, and the smaller the BER is, the better the communication quality is; the larger the PER is, the worse the communication quality is, and the smaller the PER is, the better the communication quality is; the larger the delay, the worse the communication quality, and the smaller the delay, the better the communication quality; the lower the communication rate, the worse the communication quality, and the higher the communication rate, the better the communication quality.

In some embodiments, the 5G network data may also be CSI during WIFI-5G communication. Take CSI data such as [ e, f, G, h ], [ i, j, k, l ], [ m, n, o, p ] for the 5G network data 1, 5G network data 2, 5G network data 3, respectively, as an example, where e, f, G, h are data of CSI corresponding to each antenna in the antenna combination 1, i, j, k, l are data of CSI corresponding to each antenna in the antenna combination 2, and m, n, o, p are data of CSI corresponding to each antenna in the antenna combination 3. By comparing the amplitudes of [ e, f, g, h ], [ i, j, k, l ], [ m, n, o, p ], a set of data with the largest amplitude is obtained, for example, the amplitude of [ e, f, g, h ] is the largest, so that it can be determined that the communication quality of the antenna assembly 1 corresponding to [ e, f, g, h ] is the best.

As to a procedure of how to judge the communication quality based on CSI, an exemplary description is made herein:

the CSI can describe the fading factor of the signal on each transmission path, that is, the CSI may include the value of each element in the channel gain matrix, such as signal scattering (scattering), environment fading (fading), including multipath fading and shadow fading, distance fading (power fading) and other information. The information carried by the CSI can enable the communication system to adjust to adapt to the current channel condition, and guarantees are provided for high-reliability and high-speed communication in the multi-antenna system.

Usually, the directly acquired channel information is a Channel Frequency Response (CFR), and a time domain of the CFR is represented by a Channel Impulse Response (CIR), and the CFR and the CIR may be interchanged through a fourier transform and an inverse transform. The CSI is a sampled version of the CFR.

After the CFR data is obtained, the characteristic information can be identified through a digital signal processing method. Taking a wireless router with multiple-input multiple-output (MIMO) 4 × 4 as an example, each antenna has its own tag. In the graphs a and b in fig. 4, the vertical axis represents amplitude, and the horizontal axis represents frequency offset from the center frequency point of the signal. The four curves in the graph a in fig. 4 are data of real parts of CRFs corresponding to the four antennas, respectively, and the four curves in the graph b in fig. 4 are numerical values of imaginary parts of CRFs corresponding to the four antennas, respectively. It should be noted that, by sampling the four curves in the diagram a in fig. 4, data of real parts of CSI corresponding to the four antennas can be obtained, for example, as shown by circles on the four curves in the diagram a in fig. 4;the four curves in the b diagram in fig. 4 are sampled to obtain data of imaginary parts of CSI corresponding to the four antennas, for example, as shown by circles on the four curves in the b diagram in fig. 4. Alternatively, after the absolute value of the CSI data in the a diagram in fig. 4 is taken, the absolute value of the real part of the CSI shown by the circles on the four curves shown in the a diagram in fig. 5 is obtained, and then the communication quality can be determined according to the magnitude of the value of the vertical axis of the curve in the a diagram in fig. 5, which antenna corresponds to a larger value indicates that the signal is better, and which antenna corresponds to a smaller value indicates that the signal is worse. Taking the graph a in fig. 5 as an example, the amplitude threshold of the CSI may be set to 1000, where communication quality greater than or equal to the amplitude threshold satisfies the communication requirement, and communication quality less than the amplitude threshold does not satisfy the communication requirement. Optionally, the CFR data may be subjected to inverse fourier transform to obtain data of the four curves in the graph a in fig. 5 in the time domain, as shown in the graph b in fig. 5, a larger vertical axis value in the graph b in fig. 5 indicates that the power of the signal is stronger, and the signal quality is better, and a smaller vertical axis value in the graph b in fig. 5 indicates that the power of the signal is weaker, and the signal quality is worse. Taking the graph b in fig. 5 as an example, the power threshold of the CIR may be set to

The CIR is greater than or equal to the power threshold, indicating that the communication quality meets the communication requirements, and less than the power threshold, indicating that the communication quality does not meet the communication requirements.

In fig. 4 and 5, the values of the amplitude and the power represented by the vertical axis are not actual values of the amplitude and the power, but normalized values representing the amplitude and the power may be used to compare the amplitudes.

For the present application, the wireless router may determine whether the antenna combination satisfies the communication requirement by comprehensively judging the magnitude of the real part absolute values of CSI of multiple antennas in the antenna combination; or the absolute value of the real part of the CSI corresponding to the directional antenna in the antenna combination is independently judged to determine whether the antenna combination meets the communication requirement; the magnitude of the real part absolute value of the CSI corresponding to the directional antenna may also be determined first, and then the magnitude of the real part absolute value of the CSI corresponding to the other omnidirectional antennas in the antenna combination may be determined, which is not limited in this application. It should be noted that, when comparing the magnitude of the absolute value of the real part of the CSI, the average value in a section of frequency may be taken, the maximum value in a section of frequency may be taken, or the average value may be taken after the absolute values of the real part of the CSI obtained continuously and repeatedly in a section of time are accumulated, which is not limited specifically.

Optionally, the 2.4G network data 1 may be directly acquired network data, such as CSI-1, or may be a network data range after data expansion of the directly acquired network data, for example, the network data range 1 of the CSI after data expansion of the CSI-1 is ± 5% of the value fluctuation range of the CSI-1. For example, the range of network data after data expansion is [ a + -5%, b + -5%, c + -5%, d + -5% ]. This CSI data range 1 can characterize a location within a certain area centered on the location B, for example, the CSI network data range 1 can characterize a location within the area C shown in fig. 3, that is, if the CSI-1 acquired by the wireless router 100 to the terminal device is in this CSI network data range 1, it indicates that the terminal device is in the area C.

Optionally, the 2.4G network data 1 may also be RSSI-1 of the WIFI-2.4G network, or RSSI range 1 after the RSSI-1 is subjected to data expansion. For example, when the obtained RSSI-1 is 75dBm, the RSSI range 1 after the data expansion of the RSSI-1 is 75dBm + -10%.

Optionally, the 2.4G network data 1 may also be BER-1 of a WIFI-2.4G network, or BER range 1 after data expansion is performed on BER-1. For example, when the obtained BER-1 is 0.1%, the BER range 1 after data expansion of the BER-1 is 0.09% -0.11%.

Optionally, the 2.4G network data 1 may also be a PER-1 of the WIFI-2.4G network, or a PER range 1 after the PER-1 performs data expansion. For example, when the obtained PER-1 is 1%, the range of the PER after the data expansion of the PER-1 is 0.9% -1.1%.

Optionally, the 2.4G network data 1 may also be the rate-1 of the WIFI-2.4G network, or the rate range 1 after data expansion is performed on the rate-1. For example, when the acquired rate-1 is 120bps, the rate range 1 after data expansion by the rate-1 is 120bps ± 20%.

Optionally, the 2.4G network data 1 may also be latency-1 of the WIFI-2.4G network, or a rate range 1 after data expansion is performed by latency-1. For example, when the acquired delay-1 is 50ns, the delay range 1 after the data expansion of the delay-1 is 40 ns-60 ns.

Smartphone 202 may also search for surrounding WIFI signals and send a request to establish a WIFI connection with wireless router 100. Wireless router 100 may determine that smartphone 202 is a type of removable device based on a request with its own id sent by smartphone 202. When smartphone 202 is placed at location D, wireless router 100 may establish a set of correspondences with smartphone 202 located at location D. The wireless router may obtain 2.4G network data 2 when using a WIFI-2.4G network. Then, the wireless router 100 may use the antenna combination 1 to communicate with the smart phone 202 by using a WIFI-5G network, and obtain corresponding 5G network data 4; then, the antenna combination 2 and the antenna combination 3 are sequentially and respectively used for communicating with the smart phone 202 through a WIFI-5G network, and 5G network data 5 when the antenna combination 2 is used and 5G network data 6 when the antenna combination 3 is used are obtained. Then, the wireless router 100 may find out the 5G network data that characterizes the WIFI-5G communication quality best from the 5G network data (i.e. 5G network data 4, 5G network data 5, 5G network data 6) obtained by using different antenna combinations, for example, the found 5G network data 6 obtained by using the antenna combination 3, and then may determine that the obtained corresponding relationship when the smartphone 202 is at the position D is: 2.4G correspondence 2 of network data 2 and antenna combinations 3 and storing this correspondence 2 in a mapping base. Optionally, the correspondence 2 may also carry an identifier of the location D and an identifier of the smartphone 202.

When the position of the smartphone 202 changes, for example, the smartphone moves to the position E, the process at the position D is continuously executed at the position E, that is, the 2.4G network data 3 at the position E and the 5G network data 7 with the best WIFI-5G communication quality at the position are acquired, and then the corresponding relationship 3 between the antenna combinations 2 corresponding to the 2.4G network data 3 and the 5G network data 7 is established. Optionally, the 5G network data 7 with the best communication quality can be obtained by traversing all combinations of 5G antennas as described above, and will not be described herein again. Optionally, the correspondence 3 may also carry an identifier of the location E and an identifier of the smartphone 202.

When the position of the smartphone 202 continues to change, other positions may also be obtained, such as the corresponding relation 4, the corresponding relation 5, and the corresponding relation 6 obtained at the position F, the position G, and the position H. Optionally, the correspondence relationship 4, the correspondence relationship 5, and the correspondence relationship 6 may also carry the identifier of the position F, the identifier of the position G, and the identifier of the smartphone 202. Here, the number of the obtained corresponding relations of the smartphone 202 is 5, and the 5 corresponding relations correspond to 5 different positions respectively. The number 5 is an example, and the number of the corresponding relationships obtained by the same mobile device is not limited in the embodiment of the present application, and may be adjusted according to the size of a plurality of areas used by the mobile device or the number of directional antennas. If the area used by the movable equipment is larger, or the number of the directional antennas is more, the number of the corresponding relations which can be obtained is more; if the used area is smaller or the number of directional antennas is smaller, the number of correspondences that can be obtained is smaller.

Optionally, when the smartphone 202 is located at the same position, the wireless router may also traverse all 5G antenna combinations, and find that more than one group of antenna combinations at the position can meet the communication requirement, for example, the coverage areas covered by the high-gain beams of two directional antennas adjacent to the position overlap more, and then when the terminal device is located in the overlapping area, the wireless router may use two antenna combinations where the two directional antennas are located to have a high communication rate or a low delay, so that a corresponding relationship between a group of 2.4G network data and the two antenna combinations may be established.

Optionally, the correspondence may also be a correspondence between 2.4G network data acquired at multiple positions and a group of antenna combinations. For example, if there are two or more locations that are close to each other, it is possible that the communication rate or the delay is high or low for the two or more locations using the same antenna combination, and thus, a correspondence relationship between two or more sets of 2.4G network data and the same antenna combination can be established.

In some embodiments, the correspondence obtained for the mobile device may also be a correspondence between a plurality of network data ranges and a plurality of antenna combinations. The plurality of network data ranges may be obtained by data expansion of network data acquired at a plurality of different locations, respectively.

In the process of establishing the mapping library, the user is required to hold the smartphone 202 to move at different positions in the room.

In some embodiments, a bootstrap program may be installed on smartphone 202 to establish a mapping library, for example, by displaying bootstrap information on the interface of smartphone 202 to guide a user to move around smartphone 202 in a typical location and perform sampling of network data.

For example, after the user opens the bootstrap program on the smartphone 202, the user holds the smartphone 202 and moves to the position D, and then clicks a control for starting sampling on the interface of the smartphone 202, such as a control for "start at position 1" shown in a diagram in fig. 7, at this time, the smartphone 202 may send a sampling request to the wireless router 100, and the wireless router 100 responds to the sampling request, and may acquire a set of corresponding relationships of the smartphone 202 at the position D by using the aforementioned manners of acquiring 2.4G network data and traversing antenna combinations. After acquiring the corresponding relationship at the position D, the wireless router 100 may feed back the information of completing sampling to the smartphone 202, and after receiving the information of completing sampling, the smartphone 202 may display the word "end at position 1" shown in b of fig. 7 on the interface. After a certain time interval, for example, 10 seconds interval, the interface of smartphone 202 displays guidance information for the next location E, for example, a "location 2 start" control as shown in c of fig. 7. At this time, the user needs to hold the smart phone 202, and can continue to move the smart phone to the next position, for example, position E, and click the control of "position 2 start" on the interface, so that the wireless router 100 continues to acquire the corresponding relationship at position E under the trigger of the smart phone 202. After acquiring the corresponding relationship at the position E, the wireless router 100 may feed back the information of completing sampling to the smartphone 202, and after receiving the information of completing sampling, the smartphone 202 may display the word "end at position 2" shown in d of fig. 7 on the interface. And then, after a period of time, continuously acquiring the corresponding relation of other positions. In some embodiments, the user may also click on a control to end the sampling, such as the "done" control in the b or d diagram in view 7, to end or exit the boot flow.

The method for establishing the corresponding relation by guiding the user can guide the user to continuously move to the plurality of typical positions and sequentially acquire the corresponding relation at the plurality of positions under one database establishing operation, so that the mapping database is established by one database establishing operation, and the database establishing method is quicker and has higher efficiency. And the typical position moved by the user under guidance is also the position which can be reached in the process of using the terminal equipment at ordinary times, so that the corresponding relation established by the method accords with the daily use habit of the user, is more accurate, the accuracy of the subsequently acquired target antenna combination is improved, and the internet surfing experience of the user is improved.

In some embodiments, the user may also not be required to participate in the mapping library establishment process. Active sampling in the background by the wireless router 100, thereby obtaining multiple sets of correspondences of the mobile device at multiple locations and storing in the mapping library.

For example, when a new terminal device 200 is connected to the wireless router 100, the wireless router 100 may obtain the correspondence in the background for the terminal device 200. Alternatively, the wireless router 100 may obtain a set of corresponding relationships at preset intervals. Alternatively, if the position of the terminal device 200 is not changed or is not changed much in the adjacent preset period, the obtained corresponding antenna combinations are the same for the first network data or the data range where the first network data is located, and the wireless router 100 may discard one of the sets and store the other set of the corresponding relations in the mapping database. If the position of the terminal device 200 changes greatly in different preset periods, a new corresponding relationship may be obtained and stored in the mapping library. When the time is long enough, the coverage area of the mobile area of the terminal device 200 is wider, and the wireless router 100 can obtain more corresponding relations of more positions, thereby establishing a more comprehensive mapping library.

Alternatively, the wireless router 100 may also obtain the relative position with the terminal device 200, for example, a time of arrival (TOA) method or a time difference of arrival (TDOA) method may be adopted. When the relative positions of the two are changed greatly, since the position of the wireless router 100 is not changed easily, the wireless router 100 may consider that the terminal device 200 is at a new position, and may start a new round of process for acquiring the corresponding relationship at the new position.

The above-mentioned manner in which the wireless router 100 establishes the corresponding relationship in the background to obtain the mapping library can be obtained without the perception of the user, and the manual operation of the user is not required, so that the use threshold is reduced, and the use by the user is facilitated.

In the foregoing, how the mapping library is established by the wireless router is described in detail, and how the wireless router uses the mapping library to determine the antenna combination to be invoked when performing communication of WIFI-5G will be described below.

Fig. 8 is a flowchart illustrating an example of a method for obtaining an antenna combination according to an embodiment of the present application. Taking an execution main body as a wireless router as an example for explanation, the antenna combination obtained in the embodiment of the present application is an antenna combination called when WIFI-5G is used. The method comprises the following steps:

s801, when the terminal device communicates with the terminal device by using a first frequency band, first network data is obtained, and the first network data is used for representing a communication state when the terminal device located at a first position communicates with the terminal device by using the first frequency band.

It should be noted that, when the wireless router communicates with the terminal device, the first frequency band may be adopted, and the second frequency band may also be adopted. The frequency of the second frequency band is higher than that of the first frequency band, and all the frequencies of the second frequency band can be higher than all the frequencies of the first frequency band; alternatively, a part of the frequencies in the second frequency band may be higher than all the frequencies in the first frequency band, and another part of the frequencies in the second frequency band may coincide with a part of the frequencies in the first frequency band, which is not limited herein.

Generally, when a wireless router accesses the internet, a nearby terminal device, such as a smartphone, may access the internet by connecting to the wireless router. The wireless router and the smart phone can be communicated through network connection of two frequency bands of WIFI-5G or WIFI-2.4G. In the embodiment of the application, a method for acquiring the antenna combination called when the wireless router performs WIFI-5G communication is described by taking a frequency band with a first frequency band of WIFI-2.4G and a frequency band with a second frequency band of WIFI-5G as an example.

In the process of communication between the wireless router and the smart phone by using the frequency band of WIFI-5G, if the use scene of the smart phone changes, for example, the multipath environment changes due to rapid movement of the position, so that the signal of WIFI-5G temporarily covers a weaker signal, and the WIFI-5G network cannot be normally used for communication, the network connection of WIFI-5G with high frequency between the wireless router and the smart phone is switched to the network connection of WIFI-2.4G with low frequency, and the communication connection is maintained.

In some scenarios, if the smart phone needs high-speed or low-delay communication, the wireless router and the smart phone need to perform high-speed communication through WIFI-5G network connection. In the embodiment of the application, the wireless router does not randomly select the antenna combination of WIFI-5G to directly switch from WIFI-2.4G to WIFI-5G network connection, but searches the mapping library according to the currently acquired WIFI-2.4G network data, namely the first network data, so that a group of WIFI-5G antenna combinations with good communication quality corresponding to the first network data is obtained, and then the switching is performed to WIFI-5G network connection.

The method specifically comprises the following steps: when the terminal device is located at the first position, the wireless router may acquire the network data of the WIFI-2.4G, that is, the first network data, for example, the CSI of the WIFI-2.4G, in a process of communicating with the terminal device through the network connection of the WIFI-2.4G. The CSI can characterize, among other things, the direction and distance the terminal device at the first location is located relative to the wireless router. In the example shown in fig. 3, a rectangular coordinate system is established with the position a of the wireless router 100 as the origin. For example, the obtained CSI is h (k) = [1+ i, 2+ i, -i, 0], when the terminal device is marked to be located at the actual position coordinate as position E in fig. 3, that is, the coordinate point is [5m, -6m ].

Optionally, in step S801, when the terminal device needs to establish high-speed communication with the wireless router, for example, when the terminal device runs a game application with low latency or runs a live network application with high communication rate, and the terminal device needs to establish a WIFI-5G network connection, step S801 may be triggered; or automatically triggering after the network connection is switched from the high-rate WIFI-5G to the low-rate WIFI-2.4G, for example, triggering a reconnection process of the WIFI-5G when the network connection of the WIFI-5G is disconnected and the network connection is switched to the WIFI-2.4G, namely, triggering the step of S801.

Optionally, the first network data may also include, but is not limited to: any one or more combinations of data of CSI, RSSI, BER, PER, communication rate, delay, and the like may be used as long as it reflects the distance between the terminal device and the wireless router and the direction in which the terminal device is located in the wireless router.

In some embodiments, a memory of the wireless router may store a list of a plurality of antenna combinations in advance, and antennas in each antenna combination may be commonly used for transceiving signals of WIFI-5G. For example, each antenna combination may include one or more omni-directional antennas and one or more directional antennas. The number of antennas in each antenna combination may be determined according to a product specification of the wireless router, which is not limited in this application. For example, when the radio frequency path of the wireless router supports at most four paths of signal transceiving, the number of antennas in each antenna combination may be at most four.

S802, searching in a preset mapping library according to the first network data to obtain a target antenna combination corresponding to the first network data. And the target antenna is combined into a combined form of an antenna which is called when the terminal equipment communicates through the second frequency band.

The mapping base comprises a corresponding relation between at least one data gear and at least one antenna combination, the at least one data gear comprises a first data gear, the first data gear is associated with first network data, and the at least one antenna combination comprises a target antenna combination. After the wireless router acquires the first network data, the wireless router can search in a preset mapping library to find a first data gear associated with the first network data, and an antenna combination corresponding to the first data gear is used as a target antenna combination.

Optionally, in the manner of associating network data with data gear mentioned in this application, there are two cases:

in case 1, when the data gear is a network data range, the wireless router determines the first data gear according to the network data range in which the first network data is located. Specifically, the mapping library includes a plurality of network data ranges, and each network data range represents one data gear. The wireless router compares the first network data with the plurality of network data ranges to determine the network data range where the first network data is located, and the network data range is used as a first data gear. Then, the wireless router may determine that the antenna combination corresponding to the first data gear in the mapping library is the required target antenna combination. Taking the first network data as CSI-1: h (k) = [1.05+0.96i, 2.1+0.98i, -1.02i, 0] for example, a plurality of CSI ranges included in the mapping library, such as a CSI-1 range, a CSI-2 range, and a CSI-3 range, can be seen from table 1. The wireless router searches in the mapping base of table 1 below, and determines that CSI-1 belongs to the CSI-1 range, and the CSI-1 range corresponds to antenna combination 1, and then may determine that the corresponding target antenna combination is antenna combination 1 according to the first network data.

TABLE 1

In case 2, when the data gear is network data, the wireless router may calculate a difference between the first network data and each network data corresponding to the terminal device in the mapping library, and then determine an antenna combination corresponding to the network data with the smallest difference as the target antenna combination. In some embodiments, we can represent CSI directly by the absolute value of the real part of the original CSI data. Taking the first network data as the absolute value of the imaginary part of the CSI data, that is, CSI-0 is [0.1, 1.1, 0, 0], where 0.1, 1.1, 0, 0 are the absolute values of the real parts of the CSI data corresponding to the four antennas in the used antenna combination, respectively. The mapping base includes a plurality of CSI, such as CSI-1, CSI-2, CSI-3, and CSI-4, which can be seen from table 2. The wireless router may calculate the degree of difference between CSI-0 and each CSI in the mapping base as shown in table 2 below. For example, the wireless router obtains that the difference degrees of the CSI-0 and the CSI-1, the CSI-2, and the CSI-3 are 10%, 50%, 100%, and 75%, respectively, and then finds the CSI-1 with the minimum difference degree of 10% from the CSI-0, and takes the antenna combination 1 corresponding to the CSI-1 as the target antenna combination.

TABLE 2

The CSI in table 2 represents four quadrant regions of a rectangular coordinate system established with the wireless router as the origin, and as shown in fig. 6, each antenna combination may cover one corresponding quadrant.

For example, the number of the arrays in each CSI group is four values, and the four values represent the multipath information of four antennas in the antenna combination respectively. Taking a real number as an example, the first quadrant is covered by the antenna combination 1, the array corresponding to the CSI-1 may be [0, 1, 0, 0], and it represents that the channel multipath information marked as the second antenna accounts for the main influence factor; the second quadrant is covered by an antenna combination 2, an array corresponding to CSI-2 can be [0, 0, 1, 0], and the indication marks that the channel multipath information corresponding to the third antenna accounts for the main influence factors; the third quadrant is covered by an antenna combination 3, an array corresponding to CSI-3 can be [0, 0, 0, 1], and the channel multipath information marked as the fourth antenna accounts for the main influence factors; the fourth quadrant is covered by an antenna combination 4, and the array corresponding to CSI-4 may be [1, 0, 0, 0], which indicates that the multipath information of the channel marked as the first antenna accounts for the main influence factor.

In addition, the overlapping area between two antenna combinations indicates that two pieces of channel multipath information corresponding to two adjacent antennas in the antenna combination account for the main influence factor. For example, [0, 0, 0.5, 0.5] may indicate that the channel multipath information marked as the third antenna and the fourth antenna is the main influence factor, and the corresponding areas are areas adjacent to the second quadrant and the third quadrant; [0.5, 0, 0, 0.5] can indicate that the channel multipath information marked as the first antenna and the fourth antenna occupies the main influence factors, and the corresponding areas are the areas adjacent to the third quadrant and the fourth quadrant; [0.5, 0.5, 0, 0] can indicate that the channel multipath information marked as the first antenna and the second antenna accounts for the main influence factor, and the corresponding area is the area adjacent to the fourth quadrant and the first quadrant; [0, 0.5, 0.5, 0] may indicate that channel multipath information labeled as the second antenna and the third antenna is the main influence factor, and the corresponding area is an area adjacent to the first quadrant and the second quadrant. By analogy, according to the difference of the position (distance and phase in the rectangular coordinate system), more corresponding relations of CSI, area and antenna combination can be obtained.

And after the wireless router acquires the target antenna combination, updating the target antenna combination to the configuration parameters of the antenna. The wireless router may then invoke the configuration parameter and then control the switch of the corresponding rf path to switch according to the configuration parameter. For example, the control instruction is sent to the switches on the radio frequency paths through a general input/output interface (GPIO), so that the radio frequency paths are switched, the radio frequency paths corresponding to the antennas in the target antenna combination are opened, and the antennas in the target antenna combination are used to receive and transmit the signals in the first frequency band. For example, if the wireless router shown in fig. 2 determines that the target antenna combination includes the omnidirectional antenna 101, the omnidirectional antenna 103, and the directional antenna 107, the switch logic of the radio frequency path may be controlled by a GPIO, the paths of the omnidirectional antenna 101, the omnidirectional antenna 103, and the directional antenna 107 are opened, and the omnidirectional antenna 101, the omnidirectional antenna 103, and the directional antenna 107 are used to transmit and receive signals in the first frequency band. For example, as shown in fig. 9, the wireless router controls the switches to be switched by GPIO, the switches 1-1 and 3-3 are turned on, and the switch 2 is turned on by 1-3.

In fig. 9, the WIFI chip is configured to modulate and demodulate a WIFI signal, the Power Amplifier (PA) is configured to amplify a transmission signal from the WIFI chip, the Low Noise Amplifier (LNA) is configured to amplify a reception signal from the antenna and input the amplified reception signal to the WIFI chip, and a transmission path where the PA is located and a reception path where the LNA is located are switched by a Single Pole Double Throw (SPDT) switch. Wherein, PA1, PA3, PA5 and PA7 are PAs on the transmitting path of 2.4G path 1, 2.4G path 2, 2.4G path 3 and 2.4G path 4, respectively, and LNA1, LNA3, LNA5 and LNA7 are LNAs on the receiving path of 2.4G path 1, 2.4G path 2, 2.4G path 3 and 2.4G path 4, respectively; PA2, PA4, PA6, PA8, PA9 are PAs on the transmit path of 5G path 1, 5G path 2, 5G path 3, 5G path 4, and 5G path 5, respectively, and LNAs 2, LNA4, LNA6, LNA8, and LNA9 are LNAs on the receive path of 5G path 1, 5G path 2, 5G path 3, 5G path 4, and 5G path 5, respectively; the SPDT1 is used to switch the 2.4G channel 1 and the 5G channel 1, the SPDT2 is used to switch the 2.4G channel 2 and the 5G channel 2, the SPDT3 is used to switch the 2.4G channel 3 and the 5G channel 3, the SPDT4 is used to switch the 2.4G channel 4 and the 5G channel 4, the SPDT5 is used to switch the transceiving channel of the 2.4G channel 1, the SPDT6 is used to switch the transceiving channel of the 5G channel 1, the SPDT7 is used to switch the transceiving channel of the 2.4G channel 2, the SPDT8 is used to switch the transceiving channel of the 5G channel 2, the SPDT9 is used to switch the transceiving channel of the 2.4G channel 3, the SPDT10 is used to switch the transceiving channel of the 5G channel 3, the SPDT11 is used to switch the transceiving channel of the 2.4G channel 4, the SPDT12 is used to switch the transceiving channel of the 5G channel 4, and the SPDT13 is used to switch the transceiving channel 5G channel 5.

In the embodiment shown in fig. 8, the wireless router may determine the first data gear correlated with each other through the first network data of the terminal device located at the first position, and then search the first data gear in the mapping library, so as to obtain the target antenna combination with good communication quality corresponding to the first data gear. According to the method, a large amount of time and resources are not needed to be spent on traversing all antenna combinations, the first network data is searched in the pre-established mapping library, and the target antenna combination with good communication quality corresponding to the first network data can be timely and accurately determined in an open-loop mode, so that the efficiency of obtaining the antenna combination is higher, the high-gain wave beams can be timely and quickly aligned, the high-speed network connection can be timely established, and the efficiency of antenna switching is improved. Meanwhile, the method can determine the target antenna combination with good communication quality at one time, and can avoid the problem of network switching failure caused by improper antenna combination selection possibly caused by traversing different antenna combinations, thereby avoiding network interruption and improving user experience.

Optionally, before the step S801, the wireless router may further determine whether the connected terminal device is a core device, and if the terminal device is the core device, it indicates that the terminal device is a terminal device with a high-gain beam requirement, for example, the current usage scenario of the terminal device is a game application program running with low delay, or a live network application program, and the wireless router may determine that a high-rate and low-delay communication channel needs to be established by using a second frequency, for example, a frequency of WIFI-5G, in a state where a high-gain beam is aligned at this time, and then start the step of acquiring the first network data. If the terminal device is not a core device and does not have a high-gain beam requirement, the communication requirement can be met by using a first frequency band with low frequency, for example, the frequency of WIFI-2.4G, to communicate between the wireless router and the terminal device, so that the step of acquiring first network data is not required, the network connection does not need to be switched, and the system overhead can be saved.

Optionally, the core device may also be a terminal device with a special identifier, for example, a user of the terminal device is an important client, and the special identifier represents that the terminal device needs to preferentially ensure a high rate and a low delay of communication through high-gain beam alignment.

In some embodiments, the wireless router may periodically monitor a handover status of the network connection with the terminal device, and may trigger the step of acquiring the first network data if the network connection is found to be handed over to the low speed network.

In some embodiments, the wireless router obtaining the first network data may also be triggered in response to a request by the terminal device. For example, when the terminal device monitors that the network connection with the wireless router is switched from WIFI-5G to WIFI-2.4G, an antenna switching request (which may also be referred to as a request for activating high-gain beam pointing alignment) may be sent to the wireless router through the network connection with WIFI-2.4G, and the wireless router acquires current first network data and queries in a mapping library based on the antenna switching request, thereby acquiring a target antenna combination and implementing high-gain beam alignment. In the method, the wireless router responds to the antenna switching request sent by the terminal equipment to trigger the process of acquiring the target antenna combination, so that a fixed monitoring period does not need to wait for coming, the waiting time is reduced, the antenna combination is acquired more efficiently, and the user experience is improved.

During the use of the wireless router, there may be a shift in the position or direction, for example, a user accidentally touches the wireless router while plugging or unplugging the power supply, or the user actively changes the position of the wireless router. At this time, the mapping library established before may not correctly indicate the required antenna combination, so the corresponding relationship in the mapping library may be updated again to ensure the accuracy of the corresponding relationship, and further ensure the communication quality.

Optionally, the updating process may be initiated actively by the user using the terminal device, for example, a guiding procedure of the terminal device is opened to update the corresponding relationship of the terminal device, so as to obtain an updated mapping library as soon as possible, and ensure the efficiency of antenna switching.

Optionally, the updating process may also be triggered when the network connection of the WIFI-5G fails or the communication quality of the WIFI-5G does not meet the use requirement, for example, when the wireless router performs the communication of the WIFI-5G according to the antenna combination indicated in the mapping library, the communication rate is too low or the delay is too high, the wireless router may obtain the network data of the WIFI-2.4G again in the background, and traverse the antenna combination of the WIFI-5G again to update the corresponding relationship. For the way of updating the corresponding relationship, reference may be made to the specific description of establishing the corresponding relationship in the foregoing text, and details are not described herein again. In the embodiment, the wireless router learns the new corresponding relation in the background and updates the mapping library, so that the mapping library is ensured to be accurate, user operation is not needed, the mapping library is automatically updated under the condition that a user does not sense the mapping library, and the wireless router is convenient for the user to use.

For a complete description of the technical solution of the present application, a complete process for obtaining an antenna combination is described below with a specific embodiment. Taking a scenario that a wireless router acquires communication with a terminal device by using a frequency band of WIFI-5G as an example, the method may be as shown in fig. 10, and includes:

s1001, when the terminal device is accessed to the wireless router for the first time, the wireless router determines whether the terminal device is a mobile device.

S1002A, when the terminal device is a mobile device, the wireless router obtains multiple groups of corresponding relations of the terminal device at multiple positions through a user guiding mode or a self-learning mode of the terminal device to establish a mapping library.

S1002B, when the terminal device is a non-movable device, the wireless router obtains a set of corresponding relations of the terminal device at a fixed position through a user guiding mode or a self-learning mode of the terminal device to establish a mapping library.

And S1003, establishing a mapping library according to the corresponding relation.

And S1004, when the wireless router and the terminal equipment adopt WIFI-2.4G for communication, the wireless router acquires WIFI-2.4G network data.

S1005, searching in a mapping library according to the obtained WIFI-2.4G network data to obtain a target antenna combination corresponding to the WIFI-2.4G network data.

S1006, the configuration parameters of the target antenna combination are sent to a path switch of the wireless router to indicate path switching.

And S1007, after the path is switched, acquiring WIFI-5G network data by using the antenna in the target antenna combination.

And S1008, when the WIFI-5G network data do not meet the communication requirements, re-acquiring the corresponding relation to update the mapping library.
