[0001] This invention relates to the field of dual-domain private network construction technology, and in particular to the construction method, system, device, medium and transmission method of temporary dual-domain private networks. Background Technology

[0002] 5G and 4G are two commonly used network communication technologies in the world today. In network communication, specific industries, such as schools, government affairs, medical care, and cultural tourism, will establish their own local area networks.

[0003] Due to different specific needs and scenarios, when it is necessary to build a long-distance dual-domain private network, it is necessary to use 5G base stations for resource transmission and scheduling. However, the base stations in the existing dual-domain private network are often fixed, and the sub-base stations and the parent base station of the base station are fixed. However, during the use of public 5G communication transmission, signal fluctuations are likely to occur during data transmission, resulting in unstable signal transmission. Summary of the Invention

[0004] To address one of the aforementioned problems, the present invention aims to provide a method, system, apparatus, medium, and remote method for constructing a temporary dual-domain private network, which can provide a method for constructing a temporary dual-domain private network and improve the transmission stability of the temporary dual-domain private network.

[0005] On the one hand, the present invention provides a method for building a temporary dual-domain private network, including the following steps:

[0014] If the first signal coverage area is discontinuous between any two of the demanding terminals, it is determined that the first base station set does not meet the communication conditions; if the first signal coverage area is continuous between any two of the demanding terminals, it is determined that the first base station set meets the communication conditions.

[0015] Optionally, obtaining the second base station set based on the first base station set and the first candidate base station set specifically includes:

[0016] The current base station set is obtained based on the first base station set and the first candidate base station set. The first candidate base station set is used as the current candidate base station set. It is determined whether the current base station set meets the communication conditions. If the current base station set does not meet the communication conditions, a second candidate base station set is obtained based on the current candidate base station set. A third base station set is obtained based on the second candidate base station set and the current base station set.

[0017] Using the third base station set as the current base station set and the second candidate base station set as the current candidate base station set, return to determine whether the current base station set meets the communication conditions, until the current base station set meets the communication conditions, and then use the current base station set as the second base station set.

[0018] Optionally, the method further includes optimizing the signal connection, which specifically includes:

[0019] Acquire communication data and / or resource data of the base station; the resource data includes base station type identification data and load count;

[0020] The stability of the signal connection is determined based on the communication data, and the signal connection is optimized based on the stability.

[0021] and / or

[0022] The remaining available resources of the base station are determined based on the resource data, and the signal connection is optimized based on the remaining available resources.

[0023] Optionally, the method further includes authentication usage, which specifically includes:

[0024] Accept connection requests from demanding terminals;

[0025] Authentication is performed based on the connection request. If the authentication is successful, the terminal in need is connected to the temporary dual-domain private network.

[0026] On the other hand, the present invention provides a data transmission method based on a temporary dual-domain private network, comprising the following steps:

[0027] A temporary dual-domain private network for assisting remote work is obtained according to the method described above; the required terminal includes the assisting terminal in assisting remote work.

[0028] The field data of any one assistance terminal is transmitted to other assistance terminals through the temporary dual-domain private network; the field data includes one or more of the following: display screen data, camera data, microphone data, or operation panel data.

[0029] On the other hand, the present invention provides a system for constructing a temporary dual-domain private network, comprising a first module, a second module, and a third module; wherein,

[0030] The first module is used to obtain the terminal location of the required terminal within the temporary dual-domain private network, and to search based on the terminal location to obtain a first base station set; the temporary dual-domain private network includes at least two required terminals;

[0031] The second module is used to determine whether the first base station set meets the communication conditions. If the first base station set does not meet the communication conditions, a first candidate base station set is obtained based on the first base station set, and a second base station set is obtained based on the first base station set and the first candidate base station set. The communication conditions include that the first signal coverage area of ​​the base station set is continuous between every two demanding terminals.

[0034] At least one processor;

[0035] At least one memory for storing at least one program;

[0036] When the at least one program is executed by the at least one processor, the at least one processor performs the method described above.

[0037] On the other hand, the present invention provides a computer-readable storage medium storing a processor-executable program, which, when executed by a processor, is used to perform the methods described above.

[0038] Implementing this invention provides the following beneficial effects: This invention obtains the terminal locations of demanding terminals within a temporary dual-domain private network, searches based on these locations to obtain a first set of base stations, which includes at least two demanding terminals within the temporary dual-domain private network. It then determines whether the first set of base stations meets the communication conditions. If the first set does not meet the communication conditions, a first candidate base station set is obtained based on the first set of base stations. A second set of base stations is then obtained based on the first set of base stations and the first candidate base station set. The communication conditions include that the first signal coverage area of ​​the base station set is continuous between every two demanding terminals. A signal connection is established based on the second set of base stations, thus obtaining the temporary dual-domain private network. By first obtaining the location of the demanding terminals, determining the communication base stations based on the terminal locations, and ensuring that the signal coverage area of ​​the base stations ultimately establishing the signal connection satisfies the condition of continuity between every two demanding terminals (i.e., forming a continuous signal coverage area between every two demanding terminals), this invention provides a temporary dual-domain private network, reducing fluctuations in signal transmission and improving the transmission stability of the temporary dual-domain private network.

[0054] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The step numbers in the following embodiments are only for ease of explanation and do not limit the order of the steps. The execution order of each step in the embodiments can be adapted according to the understanding of those skilled in the art.

[0055] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0056] In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first / S100," "second / S200," "third / S300," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0057] It is understood that the temporary dual-domain private network construction method provided in this embodiment of the invention can be applied to any computer device with data processing and computing capabilities, and this computer device can be various terminals or servers. When the computer device in the embodiment is a server, the server is an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. Optionally, the terminal can be a smartphone, tablet, laptop, or desktop computer, but it is not limited to these.

[0058] like Figure 1 As shown, Figure 1 This invention provides a method for setting up a temporary dual-domain private network, comprising the following steps:

[0059] S100: Obtain the terminal location of the required terminal within the temporary dual-domain private network, and search based on the terminal location to obtain the first base station set.

[0060] The temporary dual-domain private network includes at least two demand terminals. These demand terminals are those that need to communicate using the temporary dual-domain private network. Once the temporary dual-domain private network is established, signals can be transmitted between any two demand terminals through it.

[0061] Specifically, the request can be initiated by, but is not limited to, a demand terminal. The request includes demand data items. Upon receiving the request from the demand terminal, the request is parsed to obtain the demand data items, which include the terminal location. Based on the locations of every two terminal units, a geographical path is determined between each pair of demand terminals. Base stations located along this geographical path are then searched to obtain the first set of base stations.

[0062] S200. Determine whether the first base station set meets the communication conditions. If the first base station set does not meet the communication conditions, obtain the first candidate base station set based on the first base station set, and obtain the second base station set based on the first base station set and the first candidate base station set.

[0063] The communication conditions include that the first signal coverage of the base station set is continuous between every two demanding terminals.

[0064] In some embodiments, communication conditions may further include communication thresholds, which may include, but are not limited to, the data transmission stability of the base station, available bandwidth, and network load.

[0065] It is worth noting that each base station in the first base station set may have overlapping second signal coverage areas due to its own communication range and coordinate location. When there are two or more demanding terminals, and these terminals are not located within the second signal coverage area of ​​the same base station, based on the terminal location, the first base station set needs at least two base stations whose second signal coverage areas respectively include at least two demanding terminals. If the second signal coverage areas of these two base stations do not overlap, at least one base station's second signal coverage area can overlap with the second signal coverage areas of the aforementioned two base stations, forming a continuous whole. This allows the base stations to be connected based on the overlapping portions of their second signal coverage areas. Therefore, "continuous" can be interpreted as the existence of overlapping second signal coverage areas of several base stations, such that between two demanding terminals, the second signal coverage areas of all base stations can be connected into a continuous whole. Figure 2 As shown, Figure 2 This is a schematic diagram showing the relationship between a first set of base stations and a first set of candidate base stations. A - First set of base stations, B - First set of candidate base stations, C (dashed circle) - Signal coverage area. In the diagram, base stations 1 and 2 at the top, as well as base stations B1-B3 in the first set of candidate base stations, are connected as a whole and are continuous. The base stations ... (base station 3-n-1), base station n, and base stations B4-B5 in the first set of candidate base stations at the bottom cannot be connected as a whole and are discontinuous.

[0066] Specifically, the first signal coverage area of ​​the first base station set is determined based on all the second signal coverage areas. If the first signal coverage area is not continuous between any two demanding terminals, the first base station set is determined not to meet the communication conditions. If the first signal coverage area is continuous between any two demanding terminals, the first base station set is determined to meet the communication conditions.

[0067] If the first set of base stations does not meet the communication conditions, search for base stations whose second signal coverage overlaps with the second signal coverage of the base stations in the first set of base stations to obtain the first candidate base station set, such as... Figure 3 As shown, Figure 3 This is a schematic diagram illustrating the relationship between a first set of base stations and a second set of candidate base stations.

[0068] In some embodiments, if the first base station set does not meet the communication conditions, it can be determined first that the first base station set does not meet the communication conditions. For example, if the first base station set contains base stations whose second signal coverage is interrupted by other base stations, these base stations are used as secondary positioning base stations to search for base stations whose second signal coverage overlaps with the second signal coverage of the secondary positioning base stations, thus obtaining the first candidate base station set.

[0069] The current base station set is obtained based on the first base station set and the first candidate base station set. The first candidate base station set is used as the current candidate base station set to determine whether the current base station set meets the communication conditions, wherein the communication conditions are consistent with those described above.

[0070] If the current base station set does not meet the communication conditions, update the current candidate base station set according to the current candidate base station set to obtain the second candidate base station set. Update the current base station set according to the second candidate base station set and the current base station set to obtain the third base station set.

[0071] Using the third base station set as the current base station set and the second candidate base station set as the current candidate base station set, return to determine whether the current base station set meets the communication conditions, until the current base station set meets the communication conditions, and then use the current base station set as the second base station set.

[0072] This step allows for the acquisition of a second set of base stations that meet the communication requirements. This ensures that the signal coverage areas of the base stations establishing the signal connection overlap, forming a complete line without interruptions. This reduces fluctuations in signal transmission and improves the stability of the temporary dual-domain private network.

[0073] S300: Establish a signal connection based on the second base station set to obtain a temporary dual-domain private network.

[0074] Specifically, after obtaining the second set of base stations, the base stations that can form the shortest communication distance in the second set of base stations are selected for signal connection to obtain a temporary dual-domain private network. Alternatively, a signal connection can be established by selecting one of the base stations that meet the communication conditions from the second set of base stations to obtain a temporary dual-domain private network.

[0075] In some embodiments, the second base station can be selected to connect N base stations with high data transmission stability to form a temporary dual-domain private network.

[0076] Alternatively, a second base station can be selected to connect N base stations with high data transmission stability to form a temporary dual-domain private network.

[0077] Alternatively, a second base station can be selected to connect the N base stations with the highest remaining available resources to form a temporary dual-domain private network. Regardless of the method, the base stations connecting the signals must prioritize ensuring continuity between the two requesting terminals.

[0078] In some embodiments, such as Figure 4 and Figure 5 As shown, Figure 4 This is a flowchart illustrating the steps to obtain the first set of base stations. Figure 5This is a schematic diagram illustrating the relationship between a first set of base stations and a demanding terminal. In the diagram, an upward arrow with the subscript number 1 indicates that the base station is a base station in the first set of base stations. In step S100, a search is performed based on the terminal location to obtain the first set of base stations, specifically including:

[0079] S110. Determine the geographical path between every two demanding terminals based on the terminal location.

[0080] The demand terminal includes the request initiator and the request response terminal, and there can be more than one request response terminal.

[0081] Specifically, determine the locations of any two demand terminals, take the location of one demand terminal as the starting point and the location of the other demand terminal as the ending point, and connect the ending point and the starting point to form a geographical path between the two demand terminals. The geographical path can be a straight path or a path range extending from a straight path.

[0082] In this embodiment, there can be at least two demand terminals. When there are two demand terminals, one geographical path can be obtained; when there are two demand terminals, three geographical paths can be obtained; when there are three or more demand terminals, multiple geographical paths can be obtained. There are 10 geographical paths, where m is the number of demand terminals.

[0083] S120. Search for base stations along the geographical path to obtain the first set of base stations.

[0084] Specifically, based on the geographical path between two demanding terminals, base stations located along the geographical path are searched to obtain the first set of base stations.

[0085] The first base station set includes at least one base station. The demanding terminal should be located within the signal coverage area of ​​the base station in the first base station set, but it does not have to be located within the signal coverage area of ​​the same base station. For example, if there are two demanding terminals, the two demanding terminals can be located within the signal coverage area of ​​the same base station. In this case, the first base station set is considered to meet the communication conditions. Alternatively, the two demanding terminals can be located within the signal coverage areas of two different base stations. In this case, it is necessary to determine whether the first base station set meets the communication conditions.

[0086] Through steps S110-S120, the geographical path is first determined, and the first base station set is searched on the geographical path so that the base stations in the first base station set are close to the demanding terminal. This simplifies the process of obtaining the second base station set and shortens the communication distance after the signal connection.

[0087] In some embodiments, such as Figure 6 As shown, Figure 6 This is a flowchart illustrating the steps for determining whether a first set of base stations meets communication conditions. Step S200, determining whether the first set of base stations meets communication conditions, specifically includes:

[0088] S210. Determine the second signal coverage range of each base station in the first base station set, and determine the first signal coverage range of the first base station set based on all the second signal coverage ranges.

[0089] Specifically, each base station stores hardware information data, which includes, but is not limited to, model number, etc.

[0090] The hardware information data of each base station in the first base station set is obtained. Based on the hardware information data, the basic data of each base station in the first base station set is obtained. Based on the basic data of each base station, the communication range corresponding to the base station is queried. The communication range refers to the area formed by the farthest distance that the signal can be transmitted from the base station. Based on the installation location and communication range of the base station, the second signal coverage range of each base station is obtained. The second signal coverage range refers to the geographical mapping of the communication range of the base station.

[0091] The union of the second signal coverage ranges of all base stations is taken as the first signal coverage range of the first base station set. If there are two demand terminals and the two demand terminals are located within the second signal coverage range of a base station, the second signal coverage range of that base station is the first signal coverage range.

[0092] S220. When the coverage area of ​​the first signal is discontinuous between any two demanding terminals, it is determined that the first base station set does not meet the communication conditions; when the coverage area of ​​the first signal is continuous between any two demanding terminals, it is determined that the first base station set meets the communication conditions.

[0093] Specifically, in the aforementioned composition Geographical routes In a group of demand terminals, each group consists of two demand terminals. A group of demand terminals can be selected sequentially to determine if the first signal coverage is continuous among the terminals in that group, or a group can be selected randomly. There are no restrictions on this, as long as all terminals can be traversed. Group demand terminals.

[0094] If the first signal coverage area is discontinuous among one group of demanding terminals, the first base station set is determined not to meet the communication conditions; conversely, if the first signal coverage area is within... If all demand terminals in a group are continuous, the first base station set is determined to meet the communication conditions. If there are two demand terminals located in one base station, the first base station set is determined to meet the communication conditions.

[0095] The meaning of "continuous" is the same as that mentioned above, and will not be repeated here.

[0096] In some embodiments, such as Figure 7 and Figure 8 As shown, Figure 7 A flowchart illustrating the steps to obtain a second set of base stations. Figure 8 This refers to a schematic diagram illustrating the relationship between a first set of base stations, a first set of candidate base stations, and a current set of candidate base stations. In the diagram, D represents a second set of candidate base stations, and E represents base stations from the second set of candidate base stations that update the current set of base stations. Step S200 obtains the second set of base stations based on the first set of base stations and the first set of candidate base stations, specifically including:

[0097] S230. Obtain the current base station set based on the first base station set and the first candidate base station set. Use the first candidate base station set as the current candidate base station set. Determine whether the current base station set meets the communication conditions. If the current base station set does not meet the communication conditions, obtain the second candidate base station set based on the current candidate base station set. Obtain the third base station set based on the second candidate base station set and the current base station set.

[0098] The meaning of communication conditions is the same as explained above.

[0099] like Figure 9 As shown, Figure 9 This is a final result diagram for obtaining the second set of base stations. In the diagram, the upward arrow with the subscript "2" represents the base stations in the first set of base stations, the upward arrow with the subscript "11" represents the first candidate base station in the first candidate base station set, and the upward arrow with the subscript "111" represents the second candidate base station based on the second candidate base station set.

[0100] Specifically, taking a geographical path as an example, the union of the first set of base stations and the first set of candidate base stations can be used as the current set of base stations. Alternatively, a subset of base stations can be determined from the first set of candidate base stations, added to the first set of base stations to obtain the current set of base stations, and then the first set of candidate base stations can be assigned to the current set of candidate base stations. The method for determining whether the current set of base stations meets the communication conditions is the same as the aforementioned steps S210-220, the difference being the number of base stations used.

[0101] If the current set of base stations does not meet the communication conditions, similar to obtaining the second set of candidate base stations, the second signal coverage range of the base stations in the current set of candidate base stations is determined, and the base stations whose second signal coverage range overlaps with the second signal coverage range of the base stations in the current set of candidate base stations are determined to obtain the second set of candidate base stations.

[0102] The method for obtaining the third base station set is similar to that for obtaining the current base station set based on the first base station set and the first candidate base station set, and will not be described in detail here.

[0103] S240. Using the third base station set as the current base station set and the second candidate base station set as the current candidate base station set, return to determine whether the current base station set meets the communication conditions, until the current base station set meets the communication conditions, and then use the current base station set as the second base station set.

[0104] Specifically, the updated third base station set is used as the current base station set, and the updated second candidate base station set is used as the current candidate base station set. The process returns to step S230, which determines whether the current base station set meets the communication conditions. The method for determining whether the communication conditions are met is similar to the aforementioned method, except for the number of base stations. This continues until a certain update determines that the third base station set meets the communication conditions, at which point the third base station set that meets the communication conditions is assigned to the second base station set. In some embodiments, if there are multiple geographical paths, steps S230-S240 are only executed on geographical paths that do not meet the communication conditions. For geographical paths that already meet the communication conditions, the selected current base station set is the set of base stations on that geographical path where a signal connection has been established.

[0105] Through steps S230-S240, the present invention can gradually increase the number of base stations based on the signal coverage of the selected base stations to gradually obtain a second set of base stations. This can reduce the geographical deviation of base stations from the required terminals and prevent the emergence of redundant base stations that could affect the communication distance of the temporary dual-domain private network.

[0106] In some embodiments, such as Figure 10 and 11 As shown, Figure 10 It is a flowchart of steps for optimizing signal connections. Figure 11 This is a schematic diagram illustrating the result of optimized signal connections. The method also includes S400 optimized signal connections, specifically including:

[0107] S410, Obtain communication data and / or resource data from the base station.

[0108] The communication data includes, but is not limited to, the detection signal and its transmission time between any two terminals requiring a signal connection. Resource data includes base station type identification data and load count.

[0109] Specifically, the signal between any two demand terminals can be obtained through current testing. One demand terminal's coordinates are the starting point, and the other's coordinates are the ending point. Multiple detection signals are consecutively emitted at the starting point, and the signals are detected at the ending point to measure the signal transmission time. Each base station stores type identification data, and load data can be obtained using detection tools.

[0110] S420. Determine the stability of the signal connection based on the communication data, and optimize the signal connection based on the stability.

[0111] Specifically, the stability of the signal is obtained based on the signal and the signal transmission time. Base stations with lower stability can be eliminated based on the stability. Base stations near the eliminated base stations whose second signal coverage can overlap with the second signal coverage of the remaining base stations, so as to meet the communication conditions, are added to the temporary dual-domain private network where a signal connection has been established.

[0112] Alternatively, base stations with lower stability can be removed based on their stability level. Multiple ranges can be expanded outward from the midpoint of the geographical path of the terminal location to obtain an extended range. Base stations within these extended ranges can be screened from the inside out. All base stations within the extended range can be sorted according to their distance from the removed base stations. Using the closest base stations as the standard, dynamic slicing technology can be used to allocate a portion of the remaining available resources from each selected base station to replace the removed base stations, thereby optimizing the temporary dual-domain private network.

[0113] For example, suppose Figure 9 The solid line in the diagram represents the establishment of communication line 1, which establishes a signal connection. During optimization, two base stations in this line are removed, for example, [the following is omitted as the text is incomplete and cannot be translated]. Figure 11 The base station indicated by the arrow in the middle grid is removed, and a new base station is selected nearby as a replacement.

[0114] S430. Determine the remaining available resources of the base station based on the resource data, and optimize the signal connection based on the remaining available resources.

[0115] Specifically, basic functional information of each base station is obtained based on type identification data, and the remaining available resources of each base station are obtained based on the functional information and load data.

[0116] Base stations are prioritized according to the amount of remaining available resources. The more remaining available resources a base station has, the higher its priority. If this is performed after the signal is established, n base stations with lower priority are removed, and new base stations are searched near the removed base stations to replace them.

[0117] Alternatively, multiple ranges can be expanded outward in a ring from the midpoint of the geographical path of the terminal location to obtain the extended range. The remaining available resources of base stations in multiple extended ranges are filtered from the inside out, and all base stations in the extended range are sorted according to the amount of remaining available resources. The base stations with the most remaining available resources are used as the standard, and the network dynamic slicing technology is used to schedule a portion of the remaining available resources of each base station to replace the corresponding base stations in the candidate base stations obtained n times, thereby optimizing the temporary dual-domain private network.

[0118] If the signal connection is executed before completion or during signal connection establishment, the second base station can skip the n base stations with lower priority and use the base station with the highest priority as the optimized base station for signal connection.

[0119] Steps S420 and S430 can be executed together, or step S420 can be executed alone, or step S430 can be executed alone. Through steps S410-S430, a portion of the base stations are allocated from the available resources of each high-priority 5G base station to establish a temporary dedicated network according to demand, which can improve the communication rate of the temporary dual-domain private network.

[0120] like Figure 12 As shown, Figure 12 This is a flowchart illustrating the steps involved in authentication. In some embodiments, the method further includes S500 authentication, which specifically includes:

[0121] S510: Accept connection requests from demanding terminals.

[0122] The connection request may include, but is not limited to, one or more of the following: username and password, digital certificate, or two-factor authentication.

[0123] S520: Perform authentication based on the connection request. If authentication is successful, connect the requesting terminal to the temporary dual-domain private network.

[0124] Specifically, the connection request is parsed to obtain the username, password, digital certificate, or two-factor authentication, etc. Authentication is performed based on the username, password, digital certificate, or two-factor authentication. If the authentication is successful, the terminal is considered to have access rights and is connected to the temporary dual-domain private network. Connecting to the temporary dual-domain private network means that the remaining available resources of the base station used to build the temporary dual-domain private network can be utilized.

[0125] After the temporary dual-domain private network is established, access permissions are restricted to a portion of the remaining available resources within each base station participating in the establishment of the temporary dual-domain private network. This ensures that only authorized users can access the remaining available resources of the base station used to establish the temporary dual-domain private network and temporarily join the temporary dual-domain private network.

[0126] Implementing this invention has the following beneficial effects: This invention first obtains the location of the demanding terminal, determines the communication base station based on the location of the terminal, and finally establishes a signal connection between the base station and the signal coverage area of ​​the base station, which satisfies the condition of continuity between every two demanding terminals, that is, a continuous signal coverage area is formed between every two demanding terminals. This can provide a temporary dual-domain private network, reduce fluctuations in signal transmission, and improve the transmission stability of the temporary dual-domain private network.

[0127] This invention simplifies the process of obtaining a second base station set by first determining the geographical path and then searching for a first base station set along the geographical path, ensuring that the base stations in the first base station set are close to the demanding terminal, thereby shortening the communication distance after signal connection.

[0128] This invention can gradually increase the number of base stations based on the signal coverage of the selected base stations to gradually obtain a second set of base stations. This can reduce the geographical deviation of base stations from the demand terminals and prevent the emergence of redundant base stations that would affect the communication distance of the temporary dual-domain private network.

[0129] This invention optimizes signals and schedules a portion of base stations to establish a temporary dedicated network, thereby improving the communication rate and stability of the temporary dual-domain private network.

[0130] like Figure 13 As shown, Figure 13 This invention provides a flowchart of a data transmission method based on a temporary dual-domain private network, comprising the following steps:

[0131] S10. Based on the previous method for setting up a temporary dual-domain private network, a temporary dual-domain private network is obtained to assist in remote work.

[0132] Among them, the demand terminals include assistance terminals used in remote work.

[0133] Specifically, the specific process is the same as the aforementioned method embodiments, and will not be repeated here.

[0134] S20. Transmit the field data of any one assistance terminal to other assistance terminals through a temporary dual-domain private network.

[0135] The on-site data includes one or more of the following: display screen data, camera data, microphone data, or operation panel data. Other assistance terminals are assistance terminals that are different from any single assistance terminal. The display screen data, camera data, microphone data, or operation panel data can be data from a display screen, camera, microphone, or operation panel connected to the assistance terminal, or it can be data from a display screen, camera, microphone, or operation panel integrated into the assistance terminal.

[0136] Assisting with remote work can be, but is not limited to, scenarios such as teaching, telemedicine, remote conferencing, smart manufacturing, or security.

[0137] Specifically, the system acquires field data from any one of the assisting terminals and transmits the field data to other assisting terminals via a temporary dual-domain private network.

[0138] In some embodiments, the present invention provides a telemedicine method based on a temporary dual-domain private network, as follows:

[0139] During the remote medical assistance process, a temporary 5G dual-domain private network establishment system based on basic resource scheduling provided by this invention was used. The hospital now needs remote medical assistance from experts to assist in remote surgery or consultation, which relies on 5G communication transmission. However, during the use of public 5G communication transmission, signal transmission may be delayed or interrupted due to network fluctuations, which may pose a considerable risk during surgery. Therefore, a temporary dual-domain private network was built using the aforementioned method for this remote assistance consultation.

[0140] In the specific implementation process, in order to facilitate the quick and easy construction of such a dedicated network with temporary needs, a temporary system is first determined according to the parties involved in the remote assistance. This system includes multiple user front-ends and demand terminals, which are located at various remote assistance sites, such as hospitals, offices, conference rooms, or the location of consulting experts. User front-ends include displays, cameras, microphones, and operation panels, while demand terminals include, but are not limited to, computers, mobile phones, and tablets.

[0141] First, a terminal in need initiates a consultation request, which is then responded to by expert users from other terminals. Based on the consultation request, the latitude and longitude of the terminal in need are determined, as well as the latitude and longitude of the base stations between the two terminals. Using the line connecting the two terminals as a reference, the location of the first base station is found, resulting in a first base station set. The first base station set includes several first base stations. It is then determined whether the first base station set meets the communication requirements.

[0142] Because the coverage area of ​​5G base stations is relatively narrow, the second signal coverage areas of the first base station may not overlap. Therefore, it is necessary to determine the communication conditions. If the communication conditions are met, a signal connection is established between the first base stations, enabling information transmission between the two demanding terminals. If the communication conditions are not met, it is first determined that the first base stations whose second signal coverage areas do not overlap are identified. These first base stations are then used as secondary positioning points. These secondary positioning points need to connect to first candidate base stations, which are base stations from the aforementioned set of first candidate base stations. It is determined that the combination of the first base station and the first candidate base station meets the communication conditions. If the combination of the first base station and the first candidate base station does not meet the communication conditions, the second candidate base station is determined in the same way, using the first candidate base station as a secondary positioning point. This process continues until the base station meets the communication conditions. Ultimately, this ensures that there is a base station with overlapping signal coverage areas between the demanding terminals, and a signal connection is established between the base stations.

[0143] During the establishment process, the available network resources on each base station are limited, and some base stations are often under long-term high load. As a result, the network resources of such base stations may not be able to be used for the construction of a dedicated network. Therefore, it is necessary to re-plan the routes connecting the above base stations.

[0144] In the specific implementation process, the available network resources of the first base station are first detected. Based on the bandwidth, transmission rate and network load of the first base station, it is determined whether the first base station can meet the communication threshold between base stations. The communication threshold includes one or more of the following: transmission rate, stability, remaining available resources, network load, etc. If there is a high-load base station in the first base station group, this base station is skipped. The bandwidth, transmission rate and network load of the first candidate base station, the second candidate base station, ..., the nth candidate base station are detected in sequence. The base station that meets the communication conditions and communication threshold for signal connection between base stations is selected as the optimized route.

[0145] If none of the aforementioned first base stations and the nth batch of candidate base stations can form a line that meets the communication conditions and thresholds, the available 5G base station resources within the geographical path range of the demanding terminal are screened. Performance indicators of the 5G base stations, such as bandwidth utilization, transmission rate, latency, and network load, are monitored. These performance indicators can be monitored and analyzed in real time using specialized performance monitoring tools or systems. Based on the consultation request, requirements for available resources of the temporary private network are proposed. For example, during a consultation, a latency of less than 200 milliseconds is required, while during a critical surgery, the latency must remain below 100 milliseconds. The 5G base station with the best performance indicators is selected for resource scheduling. When the load on 5G base stations within the geographical path range is reduced due to pedestrian traffic or usage, If the delay fails to meet the standards for the surgical meeting, multiple ranges are expanded outward in a ring from the midpoint of the geographical path of the terminal location to obtain an extended range. The remaining available resources of 5G base stations in multiple extended ranges are screened from the inside out, and all 5G base stations in the extended range are sorted according to the amount of remaining available resources. Taking the 5G base stations with the most remaining available resources as the standard, the dynamic slicing technology of the 5G network is used to schedule a portion of the remaining available resources of each 5G base station to replace the corresponding base stations in the candidate base stations obtained n times, optimize the temporary dual-domain private network, and include the terminal locations of the hospital and the authoritative experts in the temporary dual-domain private network. A series of detection signals are sent in the temporary dual-domain private network to detect the connection effect of the temporary dual-domain private network.

[0146] When the connectivity of the temporary private network fails to meet the consultation requirements (including stability), the remaining available resources within the 5G base stations establishing the temporary dual-domain private network are re-examined. All 5G base stations within the aforementioned extended range are then re-ranked based on the amount of remaining available resources. The temporary private network established by the 5G base stations with the most remaining available resources is re-selected, and a detection signal is sent again to test the connectivity of the temporary private network, as shown in steps S410-S420. This process continues until the detection signal indicates that the connectivity of the temporary private network meets the standards. Once this is achieved, the temporary dual-domain private network is completed and put into use, ensuring stable and fast communication between the two. Furthermore, after the temporary dual-domain private network is established, access permissions for a portion of the remaining available resources within each base station participating in the construction are restricted. This restriction can be achieved through authentication mechanisms such as username / password, digital certificates, or two-factor authentication, ensuring that only authorized users can access the allocated resources for temporarily joining the meeting.

The communication conditions include that the first signal coverage area of ​​the base station set is continuous between every two demanding terminals.
