[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0024] In the related art, cell reselection is triggered only based on the pre-issued signal strength threshold. Therefore, the following two types of problems may occur in actual application scenarios: First, the user-side terminal is in a cell with good signal but busy resources, resulting in repeated access failures of the user-side terminal. Because the reselection conditions are not met, the user-side terminal can only stay in the current cell and cannot try to access the second strongest neighboring cell; Second, the user-side terminal is in a cell with good signal but busy resources, resulting in extremely low throughput of the user-side terminal. At the same time, because the reselection conditions are not met, the user-side terminal can only stay in the cell. In order to solve this problem, an embodiment of the present application provides an embodiment of a method for determining a cell of a satellite network terminal. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0025] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Figure 1 The hardware structure block diagram of a computer terminal (or mobile device) for implementing the satellite network terminal cell determination method is shown. Figure 1 As shown, the computer terminal 10 (or mobile device 10) may include one or more (102a, 102b, ..., 102n are used to illustrate) processors 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory 104 for storing data, and a transmission module 106 for communication functions. In addition, it may also include: a display, an input / output interface (I / O interface), a universal serial bus (USB) port (which may be included as one of the ports of the BUS bus), a network interface, a power supply and / or a camera. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above electronic device. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0026] It should be noted that the one or more processors 102 and / or other data processing circuits described above may generally be referred to herein as "data processing circuits". The data processing circuits may be embodied in whole or in part as software, hardware, firmware, or any other combination thereof. In addition, the data processing circuit may be a single independent processing module, or may be incorporated in whole or in part into any of the other components in the computer terminal 10 (or mobile device). As described in the embodiments of the present application, the data processing circuit acts as a processor control (e.g., selection of a variable resistor terminal path connected to an interface).

[0027] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the satellite network terminal cell determination method in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, the above-mentioned satellite network terminal cell determination method is realized.

Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0028] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the computer terminal 10. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0029] The display may be, for example, a touch screen liquid crystal display (LCD) that enables a user to interact with a user interface of the computer terminal 10 (or mobile device).

[0030] Under the above operating environment, the embodiment of the present application provides a method for determining a satellite network terminal cell, such as Figure 2 As shown, the method comprises the following steps:

[0031] Step S202, in response to abnormal information of the target terminal, detecting the location of the target terminal, wherein the abnormal information is at least used to indicate that the target terminal fails to access the target cell or the throughput of the target terminal is less than a preset value;

[0032] Step S204, when the target terminal is in the overlapping area, control the target terminal to reselect to access a qualified adjacent cell, where the adjacent cell is a cell adjacent to the target cell, wherein the overlapping area is an overlapping area of ​​the target cell and the adjacent cell coverage area;

[0033] Step S206: determining whether the target terminal has completed the service to be executed in the qualified neighboring cell at least according to the throughput after the target terminal accesses the qualified neighboring cell.

[0034] Through the above steps, reselection is triggered by detecting abnormal information fed back by the target terminal, thereby achieving the technical effect of triggering reselection based on user-side feedback, thereby solving the technical problem of low flexibility in adjusting the signal cell based on the pre-issued signal strength threshold.

[0035] In step S202, the target terminal may initiate a service to obtain abnormal information, for example, if multiple access failures to the target cell occur or the throughput of the target terminal is extremely low after accessing the target cell, the above-mentioned satellite network terminal cell determination method may be executed. It should be noted that the target cell may be the cell where the target terminal is currently located.

[0036] In some embodiments of the present application, a terminal access times counter and a throughput counter may be added to determine whether the service of the current cell is normal.

[0037] In step S204, the target terminal may determine whether it is in the overlapping area according to its own location information, and if it is in the overlapping area, perform the following operations:

[0038] The target terminal resides in the cell with the strongest current signal, receives broadcast messages, and executes the cell reselection process according to the reselection parameters; determines whether the adjacent cell meets the conditions. An optional method is to measure the signal strength of the adjacent cell. In some embodiments of the present application, it also includes: determining the geographical location of the adjacent cell, etc.; if the conditions are met, the target terminal is connected to the adjacent cell (blind selection process).

[0039] Steps S202 to S206 are described below through a specific embodiment.

[0040] In step S204, in the operation of whether the target terminal can trigger reselection, an optional method is to control the target terminal to reselect and access a qualified adjacent cell when the signal strength of the target cell is less than a first signal strength value; in another optional method, when the signal strength of the target cell is greater than the first signal strength value and the abnormal information indicates that the target terminal fails to access the target cell or the throughput of the target terminal is less than a preset value, control the target terminal to reselect and access a qualified adjacent cell (perform blind selection from the target cell to a qualified adjacent cell).

[0041] It should be noted that the first signal strength can be pre-issued by the network as a signal strength threshold. In some embodiments of the present application, when no abnormal information is received, the reselection operation can be triggered according to the pre-issued first signal strength. For example, when the signal strength of the target cell is lower than the first signal strength, the target terminal is triggered to reselect; when the signal strength of the target cell is not lower than the first signal strength, if abnormal information is received, the target terminal can also be triggered to reselect. Combining the two makes the triggering conditions for the target terminal to reselect more flexible and more adaptable to actual application scenarios to ensure normal execution of the business.

[0042] In some embodiments of the present application, the location of the target terminal can be detected in the following manner: determining the center of the first satellite beam corresponding to the target cell; and determining that the target terminal is in the overlapping area when the distance between the target terminal and the center of the first satellite beam is greater than a preset distance.

[0043] In an optional manner, the qualified neighboring cell may be determined in the following manner: a cell having a signal strength greater than a second signal strength value among the neighboring cells is determined as the qualified neighboring cell, and the target terminal is connected to the target cell.

[0044] It should be noted that when there are multiple adjacent cells that meet the conditions, the adjacent cell with the strongest signal strength can be selected for access. In another way, the cell whose beam center is closest to the target terminal can be selected for access based on the geographical location of the adjacent cells.

[0045] In some embodiments of the present application, when the target terminal successfully accesses the eligible neighboring cell and the throughput of the target terminal in the eligible neighboring cell is greater than a preset throughput threshold, it is determined that the target terminal completes the service to be executed in the eligible neighboring cell.

[0046] In some other embodiments of the present application, when the target terminal fails to access the eligible neighboring cell or the throughput of the target terminal in the eligible neighboring cell is less than the preset throughput threshold, the target terminal is instructed to return to the target cell.

[0047] It should be noted that the preset distance is determined in the following manner, including: determining the radius of the area covered by the first satellite beam corresponding to the target cell; determining multiple intersection points of multiple second satellite beams of the adjacent cell and the first satellite beam; selecting two adjacent intersection points from the multiple intersection points, and determining a first distance from the center of the first satellite beam to a line connecting the two adjacent intersection points; and determining the preset distance based on the radius and the first distance.

[0048] Figure 3 A method for determining a preset distance is shown, such as Figure 3 As shown in the figure, taking the 7-color multiplexing system adopted by the high-orbit satellite as an example, each beam has 6 neighboring cells, point A is the center of the first satellite beam, points B and C are the intersection points of the first satellite beam and the second satellite beam of the adjacent cell, respectively, and the AD line segment distance represents the distance from the beam center to the line connecting points B and C; and the distance from point A to point E is the basis for judging whether the terminal is in the coverage overlap area;

[0049]

[0050] Wherein, R represents the radius of the first satellite beam.

[0051] When the distance between the target terminal and the beam center point A is greater than 0.732R, it can be determined that the target terminal is in the overlapping area, and a target terminal reselection operation can be triggered.

[0052] It should be noted that for high-orbit satellite networks, the beam center and beam radius R are both known, and these two parameters can be stored in the terminal in advance.

[0053] In order to better understand the satellite network terminal cell determination method proposed in this application, this application provides another embodiment for illustration, such as Figure 4 As shown, including:

[0054] 1. The terminal initiates the service;

[0055] 2. Enter different states depending on whether the access fails or the throughput is low:

[0056] a) If there is no business abnormality, the terminal performs normal data transmission;

[0057] b) If the service is abnormal, the terminal needs to detect whether it is in the overlapping coverage area;

[0058] 3. If the terminal is in the overlapping coverage area, the terminal needs to measure whether the neighboring area meets the requirements;

[0059] a) If the requirements are met, a blind selection is initiated;

[0060] b) If the requirements are not met, the service will continue to be carried out in the original community

[0061] 4. Initiate services in neighboring cells and enter different states according to different performances

[0062] a) Access is successful and throughput is normal, and services continue to be provided in the target cell

[0063] b) Access failure or normal throughput, fall back to the original cell;

[0064] 5. The terminal continues to perform services in the target cell, and returns to the original cell after the services are completed.
