[0002] Traditional ground-based terminal communication relies on the coverage of terrestrial base stations, which serve as the core nodes of the communication network, providing stable and high-speed data transmission services. However, in remote mountainous areas, oceans, deserts, and other regions where base stations cannot provide comprehensive coverage, there is a real dilemma of interrupted terminal information transmission and communication loss, with no alternative ground-based base stations available. Satellite communication technology provides an effective supplement to such scenarios.

[0003] However, existing satellite communication systems often use a single-point determination and access method in emergency scenarios of network outage. When faced with a large number of terminals at risk of network outage, the use of a single-point determination and access method makes it impossible to balance access efficiency and resource utilization, resulting in low efficiency of satellite network access for a large number of terminals at risk of network outage.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] This application provides a satellite-based method for terminal network access after disconnection, which can be executed by an electronic device. The electronic device can be a server, which can be an independent physical server, a server cluster composed of multiple physical servers, or a distributed device, or a cloud server that provides cloud computing services. The server can be installed on a low-Earth orbit satellite or a high-Earth orbit satellite.

[0027] Reference Figure 1 A satellite-based terminal network access disconnection method includes steps S101, S102, S103, and S104, wherein... S101, Obtain the first network connection information of the target terminal and the relative positional relationship between the communication range of the target terminal and the target satellite.

[0028] In some embodiments, the first network connection information is a dataset containing information such as the current network connectivity status, signal strength, current communication environment, and historical network outage frequency between the target terminal and the target base station installed on the ground; the relative positional relationship is the positional relationship between the latitude and longitude coordinates of the target terminal and the communication range that the target satellite can provide, which is analyzed in real time by positioning modules such as GNSS.

[0029] After selecting the target terminal from multiple initial terminals that have established communication connections with the target base station, the electronic device generates an information acquisition command and sends it to the target terminal. The target terminal responds to the information acquisition command, triggering its GNSS module and communication module to collaboratively collect and transmit the first network connection information and its location information. Simultaneously, the electronic device sends the information acquisition command to the target satellite. The target satellite responds to the information acquisition command and transmits back the geographical boundary data of its coverage area to the electronic device. After the two data are timestamped and aligned with the coordinate system, the electronic device obtains the relative positional relationship between the communication range of the target terminal and the target satellite based on the aligned location information and communication range boundary data.

[0030] S102, based on the first network connection information and relative position relationship, determine the target monitoring area corresponding to the target terminal, and obtain the second network connection information corresponding to multiple other terminals located in the target monitoring area.

[0031] In some embodiments, the target monitoring area is a geographically adjacent area constructed based on the current location of the target terminal, which is as consistent as possible with the current communication environment of the target terminal. Its boundary is dynamically defined by a communication environment similarity weighting function, which comprehensively considers terrain undulations, building obstructions, electromagnetic interference, and historical network outage thermal distribution, and dynamically calibrates by fusing meteorological data and ionospheric disturbance index in real time. The second network connection information is a dataset containing information such as the current network connectivity status, signal strength, current communication environment, and historical network outage frequency of multiple other terminals with the target base station.

[0032] The electronic device analyzes the first network connection information to obtain the target terminal's current network environment type, network connection strength, and location information, i.e., the network transmission location point. Based on the network environment type, network transmission location point, and relative positional relationship, the electronic device determines the target monitoring area corresponding to the target terminal. The target monitoring area serves as the smallest geographical unit for determining whether to trigger the target satellite to provide batch network access support. Subsequently, the electronic device generates an information acquisition command and sends it to multiple other terminals located within the target monitoring area. The multiple other terminals respond to the information acquisition command by sending their respective second network connection information to the electronic device.

[0033] S103, based on the first network connection information and the second network connection information, determine the terminal access scheme corresponding to the target monitoring area.

[0034] In some embodiments, the terminal access scheme is a control scheme that controls whether the target satellite provides network outage access support to multiple terminals, including the target terminal, within the target monitoring area, and provides specific network outage access support.

[0035] The electronic device analyzes and processes the first network connection information to determine the first sub-network information strength corresponding to multiple time points within a certain preset time period. The electronic device also analyzes and processes the second network connection information to determine the second network information strength corresponding to multiple time points within the same preset time period. Subsequently, the electronic device performs time-series alignment of the multiple first sub-network information strengths and the multiple second sub-network information strengths. Then, based on the relationship between the multiple first sub-network information strengths and the multiple second sub-network information strengths, the electronic device determines the network situation between the target terminal and multiple other terminals within the target monitoring area, and determines a terminal access scheme suitable for the target monitoring area. This terminal access scheme can be either a first terminal access scheme or a second terminal access scheme.

[0036] S104, based on the terminal access scheme, controls the target satellite to provide network access support to the target monitoring area even when the network is disconnected.

[0037] In some embodiments, the electronic device sends the terminal access scheme to the target satellite. After receiving the terminal access scheme, the target satellite executes the network outage access support instruction according to the preset control logic in the scheme, completes the coordinated access scheduling of the target terminal and multiple other terminals, and provides them with network outage access services. This enables terminals in the target monitoring area that require satellite communication support to still stably complete emergency communication in scenarios without terrestrial network coverage. Furthermore, by setting the target monitoring area and using the target monitoring area as the smallest geographical unit for the target satellite to provide network outage access support, the accuracy of resource scheduling is ensured, and the efficiency of satellite network outage access for a batch of terminals at risk of network outage is improved.

[0038] In some embodiments, before obtaining the first network connection information of the target terminal and the relative positional relationship between the communication range of the target terminal and the target satellite in step S101, the method further includes: obtaining the data transmission quality of multiple initial terminals corresponding to the target base station within a first preset unit time period; if any data transmission quality among the multiple data transmission qualities is lower than a preset data transmission quality threshold, obtaining the data transmission quality change of the initial terminal with any data transmission quality within a second preset unit time period; if the data transmission quality change is not lower than a preset data transmission quality change threshold and the data transmission quality change is positive, determining the initial terminal with any data transmission quality as the target terminal.

[0039] In some embodiments, the plurality of initial terminals include a target terminal, and the plurality of initial terminals establish a communication connection with the target base station and use the uplink channel resources of the target base station to perform periodic data reporting.

[0040] The electronic device monitors the data transmission status of multiple initial terminals in real time and obtains the data transmission quality of these terminals within a first preset time period. The electronic device then compares the obtained data transmission quality with a preset data transmission quality threshold. If any data transmission quality falls below the preset threshold, it indicates that the initial terminal corresponding to that data transmission quality has a risk of communication degradation. At this point, the electronic device further tracks the change in data transmission quality of the target terminal within a second preset time period and compares this change with a preset change. If the change in data transmission quality is not lower than the preset threshold and is positive, it indicates that the communication data transmission degradation trend of the target terminal has formed and is continuously worsening. Therefore, the electronic device formally identifies this initial terminal as the target terminal and triggers the network disconnection access support mechanism.

[0041] In step S102, the target monitoring area corresponding to the target terminal is determined based on the first network connection information and the relative position relationship, including: determining the network environment type, network connection information strength and network transmission location of the target terminal based on the first network connection information; determining the initial monitoring area based on the network environment type and network transmission location; and determining the target monitoring area based on the initial monitoring area, the relative position relationship and the network connection information strength.

[0042] In some embodiments, the network environment type is the current communication environment type of the target terminal, such as indoor, subway, high-speed mobile, etc.; the network connection information strength is the signal strength value between the target terminal and the target base station; and the network transmission location point is the real-time coordinates of the target terminal in geographic space or the relative position calculated by the base station positioning unit.

[0043] The electronic device analyzes and processes the first network connection information to obtain the network environment type of the target terminal at the current moment, the network connection information strength for communication with the target base station, and the network transmission location. The electronic device uses the network environment type as the classification basis and the network transmission location as the reference point to delineate the initial monitoring area, wherein all areas within the initial target area are of the same network environment type.

[0044] Subsequently, the electronic equipment uses the initial monitoring area as the reference area, combines the communication range boundary of the target satellite corresponding to the relative positional relationship, and the attenuation gradient of the network connection information strength, to dynamically shrink or expand the initial monitoring area, and finally determines the minimum effective monitoring area covering the real-time communication degradation path of the target terminal, i.e. the target monitoring area.

[0045] In some embodiments, determining the target monitoring area based on the initial monitoring area, relative positional relationship, and network connection information strength includes: determining the overlapping monitoring area between the initial monitoring area and the communication range based on the relative positional relationship; dividing the overlapping monitoring area based on a preset area division rule to obtain multiple sub-overlapping monitoring areas; obtaining the verification network connection information strength of the verification data corresponding to each of the multiple sub-overlapping monitoring areas; comparing the multiple verification network connection information strengths with the network connection information strength respectively, retaining the sub-overlapping monitoring areas corresponding to the verification network connection information strengths that are not higher than the network connection information strength, and integrating the retained sub-overlapping monitoring areas to obtain the target monitoring area.

[0046] In some embodiments, the electronic device determines the boundary information of the communication range of the target satellite based on the relative positional relationship, and determines the overlapping part of the communication range of the target satellite and the initial monitoring area based on the boundary information and the initial monitoring area, namely the overlapping monitoring area. The overlapping monitoring area satisfies both the consistency of the network environment type in which the target terminal is located and is within the effective communication coverage of the target satellite, thereby providing a dual constraint basis for subsequent accurate division.

[0047] Subsequently, the electronic device retrieves preset area division rules to divide the overlapping monitoring area into multiple sub-overlapping monitoring areas. The electronic device pre-sets these rules based on geographic grid accuracy and a signal attenuation model. Then, it randomly selects a verification terminal from these sub-overlapping monitoring areas and acquires the corresponding verification data, extracting its verification network connection strength. The electronic device compares the determined verification network connection strengths with the target terminal's network connection strength, retaining the sub-overlapping monitoring areas with verification network connection strengths no higher than the target terminal's strength and removing those with higher strengths. Finally, all retained sub-overlapping monitoring areas are integrated according to spatial adjacency to obtain the target monitoring area.

[0048] Step S103, based on the first network connection information and the second network connection information, determines the terminal access scheme corresponding to the target monitoring area, including: based on the first network connection information, determining the intensity of multiple first sub-network information corresponding to the target terminal within a third preset time period; based on the second network connection information, determining the intensity of multiple second sub-network information corresponding to multiple other terminals within a third preset time period, wherein there is a correspondence between the intensity of multiple first sub-network information and the intensity of multiple second sub-network information; and based on the intensity of multiple first sub-network information and the intensity of multiple second sub-network information, determining the terminal access scheme corresponding to the target monitoring area.

[0049] In some embodiments, the electronic device presets a third preset unit time period and sets multiple target time points within the preset third preset unit time period; the electronic device analyzes and performs time-series sampling on the first network connection information to extract the first sub-network information intensity corresponding to each target time point; simultaneously, the electronic device performs sampling on the second network connection information at the same time granularity to obtain the second sub-network information intensity at each target time point, thereby clarifying the network intensity mapping relationship between the target terminal and multiple other terminals at each time point; subsequently, the electronic device compares and analyzes the multiple first sub-network information intensities and the multiple second sub-network information intensities, and determines the terminal access scheme suitable for the target monitoring area based on the comparison and analysis results.

[0050] In some embodiments, determining a terminal access scheme corresponding to a target monitoring area based on multiple first sub-network information strengths and multiple second sub-network information strengths includes: determining first change information between two adjacent first sub-network information strengths among multiple first sub-network information strengths, and determining second change information between two adjacent second sub-network information strengths among multiple second sub-network information strengths; and determining a first terminal access scheme corresponding to the target monitoring area when multiple first change information and their corresponding second change information are all the same.

[0051] In some embodiments, the electronic device uses the information intensity of two adjacent first sub-networks as the smallest analysis unit, calculates the difference between the information intensity of two adjacent first sub-networks, and determines the changing trend between the information intensity of two adjacent first sub-networks based on the difference, i.e., the first change information; and uses the difference as the first change information; similarly, it uses the information intensity of two adjacent second sub-networks as the smallest analysis unit, calculates the difference between the information intensity of two adjacent second sub-networks, and determines the changing trend between the information intensity of two adjacent second sub-networks based on the difference, i.e., the second change information.

[0052] The electronic device compares the corresponding first transformation information and second change information to determine whether the changes are consistent. After comparing multiple first change information and multiple second change information, if the comparison results between each first change information and its corresponding second change information are the same, it indicates that the network fluctuations in the target monitoring area are highly synchronous, that is, the network connection status of multiple other terminals is highly consistent with the network connection status of the target terminal. At this time, the electronic device determines that the area has strong common-mode interference characteristics, and can then consider calling the target satellite to provide network access support for all terminals in the target monitoring area. Subsequently, the electronic device determines the terminal access scheme corresponding to the target monitoring area as the first terminal access scheme, which is a scheme to control the target satellite to provide network access support for all terminals in the target monitoring area.

[0053] In some embodiments, determining the terminal access scheme corresponding to the target monitoring area based on the information strength of multiple first sub-networks and multiple second sub-networks includes: determining the second terminal access scheme corresponding to the target monitoring area when the changing trends of the information strength of multiple second sub-networks corresponding to a preset number of other terminals are different from the changing trends of the information strength of multiple first sub-networks.

[0054] In some embodiments, the electronic device determines a first trend of change among the information strengths of multiple first sub-networks. Simultaneously, the electronic device determines a second trend of change among the information strengths of multiple second sub-networks corresponding to each other terminal. Subsequently, the electronic device compares the first trend and multiple second trends one by one, and counts the number of other terminals with inconsistent trends. Then, the electronic device compares the number of other terminals with a preset data volume. If it determines that the number of other terminals is greater than or equal to the preset data volume, it indicates that the network fluctuations in the target monitoring area exhibit significant asynchrony, that is, the network changes of most other terminals are inconsistent with those of the target terminal. Subsequently, using the target satellite to provide network access support to all terminals in the target monitoring area would lead to resource waste and reduced efficiency. Therefore, it is advisable to consider implementing network access support only for terminals that have been confirmed to have common-mode interference risks. Subsequently, the electronic device determines the terminal access scheme corresponding to the target monitoring area as a second terminal access scheme, wherein the second terminal access scheme is a scheme to control the target satellite to provide network access support to a portion of the identified terminals in the target monitoring area.

[0055] If the electronic device determines that the number of other terminals is less than the preset data volume, it indicates that the network fluctuations of most other terminals in the target monitoring area are highly consistent with those of the target terminal, that is, the common-mode interference has a wide and significant impact. At this time, the stability of communication across the entire area should be prioritized. Subsequently, the electronic device determines the terminal access scheme of the target monitoring area as the first terminal access scheme.

[0056] This application provides a satellite-based terminal network disconnection access device, which adopts the following technical solution: Reference Figure 2 A satellite-based terminal network access device 20 includes: an information acquisition module 201, an information determination module 202, a scheme determination module 203, and a control module 204.
