Description

Technical Field

[0001] This application relates to the field of satellite communication technology, and in particular to a satellite-based terminal communication access method, device, electronic device, and medium. Background Technology

[0002] Communication at ground terminals is primarily supported by terrestrial communication facilities such as cellular networks and Wi-Fi, i.e., ground base stations. However, when terminals are located in remote areas, at sea, or in the air where terrestrial network coverage is insufficient, the communication link between the ground terminal and the ground base station is easily interrupted due to environmental and hardware factors, resulting in the inability to transmit critical information in a timely manner. In such cases, satellite communication becomes the only reliable means to ensure the stable transmission of critical information.

[0003] However, with the continuous development of satellite communication technology, the number of communication tasks that satellites need to perform is increasing, and satellite communication resources are becoming increasingly scarce. In emergency scenarios where multiple terminals and ground base stations experience communication interruptions, the downlink communication resources of the target satellite are often insufficient to meet the communication needs of all terminals, which in turn leads to a decrease in the communication stability of terminals that need to communicate in real time and without interruption.

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 terminal communication access method, 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 ground terminal or on a low-orbit satellite.

[0027] Reference Figure 1 A satellite-based terminal communication access method includes steps S101, S102, S103, and S104, wherein... S101, upon obtaining the terminal connection completion information of the target satellite, obtain the communication encryption level and communication urgency level corresponding to multiple initial terminals respectively.

[0028] In some embodiments, the terminal connection completion information is the acknowledgment message information returned by the target satellite when multiple initial terminals within the service range of the target base station establish a short-term communication connection with the target satellite after communication disconnection; the communication encryption level is information reflecting the security requirements of terminal data transmission; and the communication urgency level is information characterizing the sensitivity of terminal services to latency.

[0029] After obtaining terminal connection completion information from the target satellite, the electronic device generates an information acquisition command and sends it to multiple initial terminals that have established communication connections with the target satellite. The multiple initial terminals respond to the information acquisition command by sending their respective information regarding communication security requirements and service timeliness requirements to the electronic device. The electronic device then calls a preset communication security requirement-communication encryption level data table and a service timeliness requirement-communication urgency level data table to map and parse the security requirement information and timeliness requirement information, obtaining the communication encryption level and communication urgency level corresponding to each initial terminal.

[0030] S102, based on multiple communication encryption levels and multiple communication urgency levels, selects the target terminal from multiple initial terminals.

[0031] In some embodiments, the target terminal is a terminal that requires real-time and uninterrupted communication services from the target satellite.

[0032] The electronic device invokes a pre-set first and second preset communication encryption level, and compares multiple communication encryption levels with the first and second preset communication encryption levels respectively. At the same time, the electronic device invokes a pre-set first and second preset communication urgency level, and compares multiple communication urgency levels with the first and second preset communication urgency levels respectively. Based on this, the electronic device selects target terminals from multiple initial terminals that meet the conditions for real-time and uninterrupted communication services from the target satellite, according to the results of the dual threshold comparison.

[0033] S103, obtain the target bandwidth usage of the target terminal, the total bandwidth of the target satellite, and the initial bandwidth usage of the other terminals among the multiple initial terminals besides the target terminal.

[0034] In some embodiments, the target bandwidth occupancy is the minimum bandwidth resource value required for the target terminal to communicate with the target satellite in real time; the total bandwidth is the amount of bandwidth resource that the target satellite can allocate in addition to performing the current communication task; and the initial bandwidth occupancy is the bandwidth resource value occupied by each other terminal during communication with the target satellite.

[0035] The electronic device generates a bandwidth information acquisition command and sends the command to multiple initial terminals, including the target terminal, and the target satellite. The multiple initial terminals and the target satellite respond to the bandwidth information acquisition command by sending back their respective target bandwidth occupancy, total bandwidth, and initial bandwidth occupancy to the electronic device. Based on the target bandwidth occupancy, total bandwidth, and initial bandwidth occupancy, the electronic device determines a scheme for the allocation of target satellite communication resources and communication methods that are compatible with the multiple initial terminals, i.e., the terminal communication scheme.

[0036] S104: Based on the target bandwidth occupancy, total bandwidth, and multiple initial bandwidth occupancy, determine the terminal communication scheme corresponding to the target satellite, and based on the terminal communication scheme, control the target satellite to provide short-term communication services to the target terminal and multiple other terminals.

[0037] In some embodiments, the electronic device uses the total bandwidth as the upper limit of bandwidth resources, and determines the remaining bandwidth after the target bandwidth occupancy allocated to the target terminal, and determines the initial total bandwidth of multiple initial bandwidth occupancy amounts. Based on the relationship between the remaining bandwidth and the initial total bandwidth, the electronic device determines the terminal communication scheme corresponding to the target satellite. The terminal communication scheme can be a first terminal communication scheme or a second terminal communication scheme.

[0038] The electronic device sends the determined terminal communication scheme to the target satellite, which then dynamically adjusts the channel allocation strategy to enable the target satellite to provide short-term communication services to multiple initial terminals, including the target terminal. In cases where the target satellite cannot simultaneously meet the downlink communication needs of multiple initial terminals, it prioritizes the real-time communication of the target terminal while also taking into account the basic communication needs of other terminals. This improves the communication stability of the target terminal and reduces the risk of long-term communication interruptions for other terminals.

[0039] Step S102, based on multiple communication encryption levels and multiple communication urgency levels, selects a target terminal from multiple initial terminals, including: comparing multiple communication encryption levels with a first preset communication encryption level, and comparing multiple communication urgency levels with the first preset communication urgency level; if any communication encryption level is greater than the first preset communication encryption level, and the communication urgency level of the initial terminal corresponding to any communication encryption level is greater than the first preset communication urgency level, then the initial terminal corresponding to any communication encryption level is determined as the target terminal.

[0040] In some embodiments, there is a one-to-one correspondence between multiple communication encryption levels and multiple communication urgency levels. The electronic device compares each of the multiple communication encryption levels with a first preset communication encryption level, and simultaneously compares each of the multiple communication urgency levels with the first preset communication urgency level.

[0041] If the electronic device determines that any of the multiple communication encryption levels is greater than the first preset communication encryption level, and the communication urgency level of the initial terminal corresponding to that communication encryption level is also greater than the first preset communication urgency level, it indicates that the initial terminal has high-priority communication qualification and needs the target satellite to provide it with real-time and uninterrupted communication services. Therefore, the electronic device identifies the initial terminal as the target terminal.

[0042] In some embodiments, if the electronic device determines that any communication encryption level is not greater than the first preset communication encryption level, and the communication urgency level of the initial terminal corresponding to that communication encryption level is also not greater than the first preset communication urgency level; or, any communication encryption level is not greater than the first preset communication encryption level, and the communication urgency level of the initial terminal corresponding to that communication encryption level is greater than the first preset communication urgency level; or, any communication encryption level is greater than the first preset communication encryption level, but the communication urgency level of the initial terminal corresponding to that communication encryption level is not greater than the first preset communication urgency level, it indicates that the initial terminal does not have high-priority communication qualifications, and the electronic device excludes it from the target terminal, and may consider short-term intermittent communication services to ensure its basic data transmission needs.

[0043] Step S102 involves selecting a target terminal from multiple initial terminals based on multiple communication encryption levels and multiple communication urgency levels. This includes comparing multiple communication encryption levels with a second preset communication encryption level, and comparing multiple communication urgency levels with the second preset communication urgency level. If a communication encryption level is greater than the second preset communication encryption level, and the communication urgency level of the initial terminal corresponding to that communication encryption level is not greater than the second preset communication urgency level, then the initial terminal corresponding to that communication encryption level is determined as the target terminal. If any communication encryption level is not greater than the second preset communication encryption level, and the communication urgency level of the initial terminal corresponding to any communication encryption level is greater than the second preset communication urgency encryption level, then the initial terminal corresponding to that communication encryption level is determined as the target terminal.

[0044] In some embodiments, the second preset communication encryption level is greater than the first preset communication encryption level, and the second preset communication urgency level is greater than the second preset communication urgency level, thereby forming a hierarchical response mechanism.

[0045] The electronic device compares multiple communication encryption levels with a second preset communication encryption level, and also compares multiple communication urgency levels with the second preset communication urgency level. If the electronic device determines that a certain communication encryption level is greater than the second preset communication encryption level, and the communication urgency level of the initial terminal corresponding to that certain communication encryption level is not greater than the second preset communication urgency level, it indicates that the initial terminal corresponding to that certain communication encryption level has a high-security but low-timeliness communication requirement, and the electronic device identifies it as the target terminal.

[0046] If an electronic device determines that any one of the multiple communication encryption levels is not greater than the second preset communication encryption level, and the communication urgency level of the initial terminal corresponding to that communication encryption level is greater than the second preset communication urgency level, it indicates that the initial terminal corresponding to that communication encryption level has a high timeliness but low security communication requirement. The electronic device also identifies it as the target terminal to prioritize ensuring the continuity of emergency services.

[0047] In step S0104, based on the target bandwidth occupancy, total bandwidth, and multiple initial bandwidth occupancy values, the terminal communication scheme corresponding to the target satellite is determined, including: determining the remaining bandwidth of the target satellite based on the total bandwidth and the target bandwidth occupancy value; summing up the multiple initial bandwidth occupancy values ​​to obtain the initial total bandwidth, and splitting the initial total bandwidth to obtain at least two sub-initial total bandwidth values; if at least two sub-initial total bandwidth values ​​are less than the remaining bandwidth, the terminal communication scheme corresponding to the target satellite is determined as the first terminal communication scheme.

[0048] In some embodiments, the electronic device calculates the difference between the total bandwidth and the target bandwidth occupancy to obtain the remaining bandwidth that the target satellite can still carry under the bandwidth resources allocated to the target terminal; at the same time, the electronic device accumulates multiple initial bandwidth occupancy values ​​to obtain the initial total bandwidth, and then splits the initial total bandwidth to obtain at least two sub-initial total bandwidth values, wherein the at least two sub-initial total bandwidth values ​​may be the same or different, and the at least two sub-initial total bandwidth values ​​are based on the multiple initial bandwidth occupancy values.

[0049] For example, the first initial bandwidth usage is 3, the second initial bandwidth usage is 4, the third initial bandwidth usage is 5, and the fourth initial bandwidth usage is 6. This is used to split the bandwidth into two sub-initial totals. The first sub-initial total is the sum of the first and fourth initial bandwidth usages, which is 9. The second sub-initial total is the sum of the second and third initial bandwidth usages, which is 9. This is to minimize the difference between the determined at least two sub-initial totals, thereby improving the balance of bandwidth allocation and communication efficiency.

[0050] Subsequently, the electronic device compares the total amount of at least two sub-initial bandwidths with the remaining bandwidth. If the electronic device determines that the total amount of at least two sub-initial bandwidths is less than the remaining bandwidth, the electronic device sets the terminal communication scheme corresponding to the target satellite as the first terminal communication scheme. The first terminal communication scheme involves transmitting the data to be forwarded by the target terminal with the target bandwidth occupancy within each preset unit time period, and associating the data to be forwarded by multiple other terminals corresponding to the total amount of at least two sub-initial bandwidths within a preset unit time period, so that the target satellite transmits the data to be forwarded by the multiple other terminals corresponding to the total amount of at least two sub-initial bandwidths within their respective preset unit time periods.

[0051] In some embodiments, the preset unit time period is set by the following steps: obtaining the data volume of data to be forwarded corresponding to multiple initial terminals corresponding to at least two sub-initial bandwidth totals respectively; filtering out the maximum data volume corresponding to at least two sub-initial bandwidth totals from the multiple data volumes; determining the ratio relationship between at least two maximum data volumes; and determining the preset unit time period corresponding to at least two sub-initial bandwidth totals based on the initial preset unit time period and the ratio relationship.

[0052] In some embodiments, the electronic device filters out the maximum data volume from the data to be forwarded corresponding to multiple initial terminals corresponding to at least two sub-initial bandwidth totals, calculates the ratio between the at least two maximum data volumes to obtain the ratio relationship between the at least two maximum data volumes, and then retrieves a pre-set initial preset unit time period and adjusts the initial preset unit time period based on the ratio relationship to determine the actual preset unit time period corresponding to each of the at least two sub-initial bandwidth totals.

[0053] In some embodiments, after summing multiple initial bandwidth occupancy amounts to obtain the total initial bandwidth, and splitting the total initial bandwidth to obtain at least two sub-initial bandwidth amounts, step S104 further includes determining the terminal communication scheme corresponding to the target satellite based on the target bandwidth occupancy amount, the total bandwidth, and multiple initial bandwidth occupancy amounts. If any one of the at least two sub-initial bandwidth amounts is greater than the remaining bandwidth, the terminal communication scheme corresponding to the target satellite is determined to be the second terminal communication scheme.

[0054] In some embodiments, if the electronic device determines that any one of the at least two sub-initial bandwidth totals is greater than the remaining bandwidth, it indicates that the remaining bandwidth resources of the current target satellite are insufficient to meet the complete forwarding requirements of the initial terminal group corresponding to that sub-initial bandwidth total. Therefore, it is possible to consider redundantly eliminating and compressing the data to be forwarded in the initial terminal group corresponding to any sub-initial bandwidth total to generate final forwarding data that is adapted to the remaining bandwidth capacity. Thus, the electronic device sets the terminal communication scheme corresponding to the target satellite as the second terminal communication scheme. The second terminal communication scheme is based on the data transmission requirements and data to be forwarded corresponding to multiple other terminals corresponding to any sub-initial bandwidth total, processes the data to be forwarded, obtains the final forwarding data, and causes the target satellite to send the final forwarding data within its corresponding preset unit time period.

[0055] In step S104, based on the terminal communication scheme, the target satellite is controlled to provide short-term communication services to the target terminal and multiple other terminals, including: when the terminal communication scheme is sent to the target satellite, obtaining the communication quality corresponding to multiple initial terminals respectively; when multiple communication qualities are all less than the preset communication quality, generating a scheme execution instruction and sending the scheme execution instruction to the target satellite, so that the target satellite provides short-term communication services to the target terminal and multiple other terminals based on the terminal communication scheme.

[0056] In some embodiments, after the electronic device sends the terminal communication scheme to the target satellite, it monitors in real time key indicators such as signal-to-noise ratio, bit error rate, and link stability of each initial terminal when it communicates uplink with the target satellite, i.e., communication quality. Subsequently, the electronic device compares the multiple communication quality values ​​obtained with the preset communication quality values. If it determines that multiple communication quality values ​​are all lower than the preset communication quality values, it indicates that the communication link of the initial terminal is on the verge of failure. At this time, the terminal communication scheme must be activated immediately. Therefore, the electronic device generates a scheme execution instruction and sends the scheme execution instruction to the target satellite so that the target satellite can provide short-term communication services to the target terminal and multiple other terminals according to the terminal communication scheme.

[0057] This application provides a satellite-based terminal communication access device, which adopts the following technical solution: Reference Figure 2 A satellite-based terminal communication access device 20 includes: a first information acquisition module 201, a target terminal determination module 202, a second information acquisition module 203, and a control module 204. The first information acquisition module 201, upon acquiring terminal connection completion information for a target satellite, acquires the communication encryption level and communication urgency level corresponding to multiple initial terminals. The target terminal determination module 202, based on the multiple communication encryption levels and multiple communication urgency levels, filters out the target terminal from the multiple initial terminals. The second information acquisition module 203, acquired, acquires the target bandwidth occupancy of the target terminal, the total bandwidth of the target satellite, and the initial bandwidth occupancy of multiple other terminals besides the target terminal.

[0060] In some embodiments, the control module 204 described above is specifically used to: determine the remaining bandwidth of the target satellite based on the total bandwidth and the target bandwidth occupancy; accumulate multiple initial bandwidth occupancy values ​​to obtain the initial total bandwidth, and split the initial total bandwidth to obtain at least two sub-initial total bandwidth values; when the at least two sub-initial total bandwidth values ​​are both less than the remaining bandwidth, determine the terminal communication scheme corresponding to the target satellite as the first terminal communication scheme, wherein the first terminal communication scheme is to transmit the data to be forwarded by the target terminal with the target bandwidth occupancy within each preset unit time period, and to associate the data to be forwarded by multiple other terminals corresponding to the at least two sub-initial total bandwidth values ​​within a preset unit time period, so that the target satellite transmits the data to be forwarded by the multiple other terminals corresponding to the at least two sub-initial total bandwidth values ​​within their respective preset unit time periods.

[0061] In some embodiments, the aforementioned preset unit time period is set by the following steps: obtaining the data volume of data to be forwarded corresponding to multiple initial terminals corresponding to at least two sub-initial bandwidth totals respectively; filtering out the maximum data volume corresponding to at least two sub-initial bandwidth totals from the multiple data volumes; determining the ratio relationship between at least two maximum data volumes; and determining the preset unit time period corresponding to at least two sub-initial bandwidth totals based on the initial preset unit time period and the ratio relationship.
