Description

Technical Field

[0001] The present application relates to the technical field of base station design, and in particular to a base station design method that can be used for 5G communication and WiFi7 communication. Background Art

[0002] The full name of "wifi7" is "7th generation wireless network technology", and "5G" is "fifth generation mobile network communication technology". The 5G base station is the core facility of the mobile communication network. It is responsible for connecting with 5G terminals (such as mobile phones, Internet of Things devices, etc.) through radio waves, providing wide-area high-speed wireless access, and accessing the core network, while "wifi7" provides local area network (LAN) high-speed access through wireless routers or APs, mainly serving small-scale scenarios such as homes and enterprises. At present, in some factories or there is a need to control the operation of robots through "5G", so 5G base stations will be laid to ensure signal stability. At present, there is a practice of applying fusion base stations in some cases. The problem is that the scope of application of Wi-Fi6 communication and the following two are seriously mismatched. With the further increase in the coverage of "wifi7", the practicality of fusion base stations has been further increased, but there are still problems that need to be solved. For example, there are problems with different coverage ranges of the two communication methods and the overlapping coverage areas at the edges of the Wi-Fi coverage of multiple base stations. When using Wi-Fi7 communication, the communication device needs to switch from the connection with one base station to another. The current switching logic of the communication device is based on signal quality. In the case of overlapping coverage areas at the edge, the signal quality provided by multiple different base stations is close. Switching to Wi-Fi7 based on the communication device itself often leads to untimely switching, until the communication device walks out of the coverage range of a certain base station and searches for a new base station to connect to, resulting in a short period of network disconnection.

[0003] In view of this, the present invention proposes a base station design method that can be used for 5G communication and WiFi7 communication, so as to solve the problem that switching to Wi-Fi7 based on the communication device itself within the coverage of the fusion base station often leads to untimely switching, and the communication device will not be disconnected from the network for a short time until it leaves the coverage of a certain base station and searches for a new base station to connect to. Summary of the Invention

[0004] In order to solve the problem of different coverage of the two communication modes and the problem that switching to Wi-Fi7 based on the communication device itself within the coverage of the fusion base station often leads to untimely switching, and the communication device will not be disconnected from the network for a short time until it walks out of the coverage of a certain base station and searches for a new base station to connect to. This application provides a base station design method that can be used for 5G communication and WiFi7 communication.

[0005] In the first aspect, the present application provides a base station design method that can be used for 5G communication and WiFi7 communication, using the following technical solutions:

[0006] A base station design method that can be used for 5G communication and WiFi7 communication includes the following steps:

[0007] Obtain geographic information of the locations of established base stations and target coverage areas, including building information and terrain information;

[0008] Obtain the coverage and signal strength of the base station 5G communication and WiFi7 communication respectively, and construct a first intensity distribution map of the 5G communication signal and a second intensity distribution map of the WiFi7 communication signal with the established base station as the center;

[0009] Set a baseline signal strength for the area where the building is located and compare the base station signal strength with the two actual signal strengths at the same location in the first intensity distribution map and the second intensity distribution map. If both actual signal strengths are less than the baseline signal strength, mark the current building as the target building. Then, obtain the baseline intensity contour line from the first intensity distribution map and the second intensity distribution map, and output the maximum distance between the baseline intensity contour line in the first intensity distribution map and the second intensity distribution map and the corresponding base station;

[0010] Draw a circle with the target building as the core and the maximum distance as the radius, and take the part of the drawn circle that does not intersect with the base station communication coverage as the target arc. Select several locations on the target arc where there are no buildings in the straight line connecting the target building as marking points, and obtain the distances between the marking points and all established base stations. Based on all the distances, obtain the distribution coefficient and select the marking point with the smallest distribution coefficient that meets the establishment requirements to establish a new base station.

[0011] Through the above technical solution: a base station design solution that can adapt to the different coverage ranges and wall penetration capabilities of 5G communication and WiFi7 communication is provided to ensure that the 5G and Wi-Fi7 signal strengths of all buildings covered by the base station communication range and their interiors can meet the requirements of production and life. In addition, the establishment of a new base station of the present invention is based on the distribution coefficient obtained based on the spacing, which can keep the straight-line distance data between the new base station and the adjacent base station more balanced to facilitate the subsequent connection of communication controlled by the base station, and maintain the user experience of WiFi7 communication at the edge of the coverage area.

[0012] Optionally, it also includes:

[0013] Numbering the communication devices connected to the base station and obtaining location information of the numbered communication devices, wherein the location information is obtained by adding a location information sharing protocol to the connection protocol;

[0014] An overlap determination area is set. When a communication device connected to a base station enters the overlap determination area, it is determined whether to disconnect the communication connection between the current base station and the mobile device based on the location information and movement time of the communication device.

[0015] Optionally, the process of obtaining the distribution coefficient based on all the intervals and selecting the distribution coefficient includes:

[0016] Determine whether other established base stations are adjacent to the new base station, and then use the formula:

[0017]

[0018] Obtain the distribution coefficient G, where δ1 and δ2 are the preset first and second weight coefficients, which are constants set based on empirical data, N1 is the number of established base stations that are determined to be adjacent to the newly established base station, and d i is the distance from the newly established base station to the i-th established base station, i and j are non-zero positive integers not greater than N1, All d i The average of the sum, is the near-point elevation angle between the base of the newly established base station and the antenna of the i-th established base station, It is the preset standard angle.

[0019] Optionally, the process of determining whether other established base stations and the new base station are in a neighboring relationship includes:

[0020] Set a predicted coverage area for the new base station and compare its location within the target coverage area with the coverage areas of other established base stations. The predicted coverage area is set based on the Wi-Fi 7 coverage area, and the location comparison object is also the Wi-Fi 7 coverage area of ​​other established base stations.

[0021] If the predicted coverage area coincides with the coverage of an established base station, the established base station and the newly established base station are determined to be in an adjacent relationship; otherwise, they are determined to be in a non-adjacent relationship.

[0022] Through the above technical solution: the process of obtaining the distribution coefficient is improved. The distribution coefficient takes into account the distance between the new base station and other base stations and the communication angle, and can ensure that each new base station can be close to the actual coverage area and signal reception angle of each adjacent base station after establishment, so that the signal quality from the two base stations in the overlapping area is close, thereby providing a stable judgment environment for determining whether to disconnect the communication connection between the current base station and the mobile device.

[0023] Optionally, the process of setting the coincidence determination area includes:

[0024] Obtaining the actual coverage of the newly established base station and the actual coverage of the existing base stations that are adjacent to the newly established base station;

[0025] Mark the outline of the overlapping part of the actual coverage area of ​​the newly established base station and the actual coverage area of ​​its adjacent base station to obtain a closed contour line;

[0026] Set the safety distance and use the safety distance as the offset distance to execute the inward offset command on the contour line to obtain a new judgment line. The area within the judgment line is the coincidence judgment area.

[0027] Optionally, the process of determining whether to disconnect the communication connection between the current base station and the mobile device based on the location information and movement time of the communication device includes:

[0028] When a communication device is brought into the coincidence determination area, the moving direction of the corresponding communication device is obtained based on the position information of the communication device at every standard time;

[0029] Determine whether the moving direction is pointing away from the base station connected to the communication device, and if so, perform a time determination, and disconnect the communication connection between the current base station and the mobile device after a preset time determination condition is met;

[0030] Otherwise, the communication connection between the current base station and the mobile device is not disconnected.

[0031] Through the above technical solution: a technical solution is provided on how to intelligently disconnect the current communication device from the base station within the overlap determination area and enable the communication device to automatically connect to the network of other base stations. During the use of Wi-Fi7 communication equipment, especially when passing through the overlap area of ​​two base stations, if the communication device is carried by the carrier and continues to move towards the coverage area of ​​the current base station, it will enter a weak signal state for a period of time. In this state, the device can receive the signal from the original base station but it is extremely weak. It often needs to move away until the signal is completely lost or manually switch to connect to the base station. In this case, the weak signal will seriously affect the communication experience. Therefore, after entering the overlap determination area, when the current communication device is carried to the coverage area of ​​other base stations, the base station actively disconnects the connection in advance to maximize the maintenance of the communication experience.

[0032] Optionally, determining whether a preset time determination condition is met includes:

[0033] Set the determination time and obtain the moving direction of each standard time communication device within the determination time;

[0034]

[0035] If the time is not determined to be satisfied, the preset time determination condition is determined to be satisfied; otherwise, it is determined that the preset time determination condition is not satisfied.

[0036] Optionally, the process of setting the determination time includes:

[0037] By formula:

[0038]

[0039] Get the judgment time T, where M is the total number of times the current communication device enters the current overlap judgment area under the same conditions, M1 is the number of times it finally moves out of the actual coverage range of the current base station in the total number of times, ε is the preset compensation index, and T0 is the preset standard time.

[0040] Optionally, the actual coverage ranges of all established base stations include all buildings in the target coverage area.

[0041] Optionally, the process of disconnecting the communication connection between the current base station and the mobile device includes:

[0042] Obtain data upload and download status of the communication device connected to the base station;

[0043] After determining that the communication connection between the current base station and the mobile device needs to be disconnected, disconnection monitoring is set. The disconnection detection monitors the data upload and download status within a preset detection time and disconnects the communication connection between the current base station and the mobile device when the sum of the data upload and download status traffic is lower than a preset threshold. The preset detection time is usually between 2-5 seconds. It should be noted that during the implementation of the present invention, the communication device needs to turn on the automatic connection function. After the disconnection, the communication device will automatically connect to other base stations.

[0044] In summary, this application includes at least one of the following beneficial technical effects:

[0045] The present invention provides a base station design scheme that can adapt to the different coverage ranges and wall penetration capabilities of 5G communication and WiFi7 communication, so as to ensure that the 5G and Wi-Fi7 signal strengths of all buildings covered by the base station communication range and their interiors can meet the requirements of production and life. In addition, the establishment of the new base station of the present invention is based on the distribution coefficient obtained based on the spacing, which can keep the straight-line distance data between the new base station and the adjacent base station more balanced to facilitate the subsequent connection of the communication controlled by the base station, and maintain the user experience of WiFi7 communication at the edge of the coverage area.

[0046] The present invention can ensure that after each new base station is established, the overlapping area and signal reception angle of the actual coverage range of each adjacent base station are close, so that the signal quality from the two base stations in the overlapping area is close, thereby providing a stable judgment environment for determining whether to disconnect the communication connection between the current base station and the mobile device.

[0047] The present invention controls the connection status of the base station. Specifically, when the Wi-Fi 7 communication device is in use, especially when passing through the overlapping area of ​​two base stations, if the communication device is carried by the carrier and continues to move towards the coverage of the current base station, it will enter a weak signal state for a period of time. In this state, the device can receive the signal from the original base station but it is extremely weak. It is often necessary to move away until the signal is completely lost or manually switch to the connection base station. In this case, the weak signal will seriously affect the communication experience. Therefore, after entering the overlapping judgment area, when the current communication device is carried to the coverage of other base stations, the base station actively disconnects the connection in advance to maximize the maintenance of the communication experience.
