Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of satellite internet network management, and particularly relates to an inter-satellite management method based on central competition arbitration. BACKGROUND

[0002] This section is intended to provide background or context to the embodiments of the application recited in the claims. The description herein does not constitute admission that the prior publication, square, or subject matter described herein and / or the material contained therein are prior art to the claimed application.

[0003] At present, each satellite is equipped with a satellite network management node, which is used as a satellite edge management node and is responsible for the management of satellite network devices on a single satellite. This measure not only enables the management function of the satellite edge node, but also greatly reduces the burden of the ground network management system, thereby building a star-ground integrated management pattern.

[0004] However, the current management method has obvious limitations, which is only for the management of a single satellite. For example, if a single point failure occurs in a satellite, the satellite network devices on the satellite will lose control, resulting in a disconnection state of the single-satellite satellite device management. This situation poses a great risk, making it difficult to achieve the goal of providing global access to wide-area intelligent connection services anytime and anywhere. SUMMARY

The method is applied to a ground network management system and includes:

[0006] After receiving a management application sent by a satellite network management node of a neighboring satellite of the first satellite, the neighboring satellite with the highest concentration priority of the management priority of the first satellite is determined as a target satellite. If the target satellite meets the management rule, the target satellite is determined as a third satellite. The management application is sent by the neighboring satellite of the first satellite when the neighboring satellite monitors the failure of the first satellite;

[0007] A management response including an agreement to manage is sent to the satellite network management node of the third satellite;

[0008] A management response including a rejection of management and a management result is sent to the satellite network management node of a second satellite of the first satellite other than the third satellite.

[0009] The embodiments of the present application also provide another inter-satellite management method based on central competition arbitration to manage satellite network devices on a first satellite and realize dynamic inter-satellite collaborative management. The method is applied to a satellite network management node of a third satellite and includes:

[0010] In response to the failure information of the first satellite, send a management application to a ground network management system;

[0011] Receive a management response fed back by the ground network management system, and if the management response includes an agreement to management, enable management of the on-board network equipment of the first satellite;

[0012] The third satellite is a satellite with the highest priority in a management priority neighboring satellite set of the first satellite of the ground network management system and that meets a management rule.

[0013] The embodiment of the application also provides another inter-satellite management method based on center competition arbitration to manage and control the on-board network equipment of the first satellite, and realizes dynamic cooperative management and control among satellites. The method is applied to an on-board network management node of a second satellite and includes the following steps:

[0014] In response to the failure information of the first satellite, send a management application to a ground network management system;

[0015] Receive a management response fed back by the ground network management system, and if the management response includes a rejection to management, record a management result in the management response;

[0016] The second satellite is a neighboring satellite of the first satellite except the third satellite, and the third satellite is a satellite with the highest priority in a management priority neighboring satellite set of the first satellite of the ground network management system and that meets a management rule.

[0017] The embodiment of the application also provides a computer device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the inter-satellite management method based on center competition arbitration is realized.

[0019] The embodiment of the application also provides a computer program product, which includes a computer program. When the processor executes the computer program, the inter-satellite management method based on center competition arbitration is realized.

[0020] The beneficial effects of the embodiments of the present application are as follows: the ground network management system is the center for inter-satellite in-corporation, the third satellite is determined by the ground network management system through competition arbitration, the target satellite is determined by directly incorporating the first satellite into the neighbor star with the highest priority, if the target satellite meets the in-corporation rule, the target satellite is determined as the third satellite, the ground network management system can quickly complete the decision, avoiding complex multi-round evaluation time-consuming, greatly shortening the in-corporation response period. At the same time, based on the preset priority rule set for decision-making, the uncertainty caused by human intervention is reduced, ensuring that the selection of the third satellite meets the optimal standard, and the accuracy of decision-making is improved. Optimize inter-satellite resource allocation and collaboration efficiency: send the response of agreeing to in-corporate to the on-board network management node of the third satellite, and send the response of refusing in-corporation and the result to the on-board network management node of other neighbor stars, which can clearly position the role of each neighbor star. This can avoid resource competition and conflict caused by multiple neighbor stars trying to in-corporate the first satellite at the same time, reasonably allocate inter-satellite resources, and enable the third satellite to concentrate resources to effectively manage the first satellite, thereby improving the overall efficiency of inter-satellite collaborative management. The entire in-corporation process is centrally arbitrated by the ground network management system, forming a standardized operation process. Each neighbor star performs corresponding operations according to the clear in-corporation response, reducing the possibility of process confusion. In addition, the response of refusing in-corporation includes the in-corporation result, so that each neighbor star can clearly understand the third satellite information, and combined with the recording mechanism, a complete in-corporation process record chain can be constructed, providing traceable basis for subsequent problem troubleshooting and process optimization. Quickly and accurately determine the third satellite and start in-corporation, which can timely fill the possible management gap of the first satellite and avoid the risk of single-satellite management disconnection. At the same time, the clear inter-satellite division of labor and collaboration mechanism improves the ability of the satellite network to respond to abnormal situations, ensures the continuity of the management of the on-board network equipment, and thus enhances the stability and reliability of the entire satellite network, laying a solid foundation for achieving the global wide-area intelligent connection service goal.

[0033] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, further detailed description of the embodiments of the present application will be given below with reference to the accompanying drawings. Herein, the illustrative embodiments of the present application and their descriptions are used to explain the present application, but not to limit the present application.

[0034] In order to solve the technical problem that the on-board network device on the target object first satellite cannot be managed and controlled in the prior art, the risk is great, and the goal of providing global access to wide-area intelligent service at any time and anywhere cannot be achieved, the present application proposes an inter-satellite management method based on center competition adjudication to manage and control the on-board network device on the first satellite, and realizes inter-satellite dynamic collaborative management.

[0035] The management strategy based on the center competition adjudication result needs to follow one principle: the neighboring star that cannot be connected with the ground network management system cannot take over the failed neighboring star.

[0036] Figure 1For the flowchart of the inter-satellite subsumption method based on center competition arbitration in the embodiments of the present application, applied to a ground network management system, comprising:

[0037] Step 101, after receiving the subsumption application sent by the on-board network management node of the neighboring satellite of the first satellite, the neighboring satellite with the highest subsumption priority of the first satellite is determined as the target satellite, and if the target satellite meets the subsumption rule, the target satellite is determined as the third satellite, wherein the subsumption application is sent by the neighboring satellite of the first satellite when monitoring the failure of the first satellite;

[0038] Step 102, sending a subsumption response including the consent of subsumption to the on-board network management node of the third satellite;

[0039] Step 103, sending a subsumption response including the rejection of subsumption and the subsumption result to the on-board network management node of the neighboring satellite of the first satellite except the third satellite.

[0040] In the method proposed in the embodiments of the present application, the ground network management system is the center for inter-satellite subsumption, and the third satellite is determined by the ground network management system. The ground network management system can quickly complete the decision, avoiding the time-consuming of complex multi-round evaluation, and greatly shortening the subsumption response period. At the same time, based on the preset priority rule set for decision-making, the uncertainty caused by human intervention is reduced, ensuring that the selection of the third satellite meets the optimal standard, and improving the accuracy of decision-making. Optimizing inter-satellite resource allocation and collaboration efficiency: sending a response agreeing to subsumption to the on-board network management node of the third satellite, and at the same time sending a response rejecting subsumption and the result to the on-board network management node of other neighboring satellites, can clearly position the roles of each neighboring satellite. This can avoid resource competition and conflict caused by multiple neighboring satellites trying to subsume the first satellite at the same time, so that inter-satellite resources are reasonably allocated, and the third satellite can concentrate resources to effectively manage and control the first satellite, improving the overall efficiency of inter-satellite collaborative management. The entire subsumption process is centrally decided by the ground network management system, forming a standardized operation process. Each neighboring satellite performs the corresponding operation according to the clear subsumption response, reducing the possibility of process confusion. In addition, the response rejecting subsumption includes the subsumption result, so that each neighboring satellite can clearly understand the information of the third satellite, and combined with the recording mechanism, a complete subsumption process record chain can be constructed, providing traceable basis for subsequent problem troubleshooting, process optimization, etc. Quickly and accurately determining the third satellite and starting subsumption can timely fill the possible management gap of the first satellite, avoiding the risk of single-satellite management disconnection. At the same time, the clear inter-satellite division of labor and collaboration mechanism improves the ability of the satellite network to respond to abnormal situations, ensuring the continuity of the management and control of the on-board network equipment, and thus enhancing the stability and reliability of the entire satellite network, laying a solid foundation for achieving the global wide-area intelligent connection service goal.

[0041] In the embodiments of the present application, the satellite management priority rules of the first satellite can be stored and managed in the form of a list, a vector, etc., which is not limited here. Table 1 is a design rule of the satellite management priority neighbor set.

[0042] Table 1

[0043]

[0044] In the embodiments of the present application, the first satellite is a satellite with a single point failure, and the first satellite has at least one neighbor satellite. In an embodiment, the method further comprises:

[0045] According to the first preset period, the neighbor satellites of each first satellite satisfying the satellite management rule are obtained, and satellite-borne network management node collected satellite management capability analysis index data of the neighbor satellites satisfying the satellite management rule are collected, the satellite management capability analysis index data at least including one of communication capability data, load state data, distance data and historical satellite management data;

[0046] According to the satellite management capability analysis index data and the corresponding weight of each neighbor satellite, a satellite management capability comprehensive value of each neighbor satellite is calculated.

[0047] According to the order from high to low of the satellite management capability comprehensive value, a satellite management priority neighbor set of the first satellite is generated.

[0048] In the embodiments of the present application, the communication capability data includes bandwidth and transmission rate, the load state data includes the number of satellite-borne network devices and resource occupancy rate, the distance includes the orbital spacing and communication delay between each satellite and the neighbor satellite, and the historical satellite management data includes the number of successful management and control times and failure handling efficiency, and the weight proportion of each communication capability data is analyzed, such as a communication capability data weight of 30% and a load state data weight of 25%. Before calculating the satellite management capability comprehensive value, the collected communication capability data is standardized and converted into a quantitative score of 0-100 (for example, the lower the communication delay, the higher the score; the lower the load rate, the higher the score), and then weighted sum is performed to obtain the satellite management capability comprehensive value of each neighbor satellite. For example, a certain neighbor satellite communication capability data is 80 points (weight 30%), load state data is 70 points (weight 25%), distance data is 90 points (weight 20%), and historical satellite management data is 85 points (weight 25%), and the satellite management capability comprehensive value is 80x30% + 70x25% + 90x20% + 85x25% = 80.5 points.

[0049] In an embodiment, the satellite management rule is that the satellite is running normally and has satellite management capability for the satellite-borne network devices of the first satellite, and the satellite management capability does not reach the upper limit of the satellite management capability.

[0050] When analyzing the third satellite with respect to the first satellite, the satellite admission rules are met, such as not exceeding the upper limit of the satellite admission capacity, so as to avoid the situation that some neighboring satellites are affected by the high load and the admission effect is affected. Through dynamic evaluation of the admission capacity of the neighboring satellites, the resources are reasonably allocated, the neighboring satellites with sufficient residual capacity are enabled to undertake the admission task, the overall utilization rate of the satellite-borne equipment is improved, and the waste of resources is avoided.

[0051] In an embodiment, the method further comprises:

[0052] After generating the satellite admission priority neighboring satellite set of the first satellite, if the difference between the admission capacity comprehensive values of multiple neighboring satellites of the first satellite is greater than a preset difference threshold, the priority order of the multiple neighboring satellites is adjusted according to the degree of coplanarity of the orbits of each neighboring satellite and the first satellite.

[0053] The preset difference threshold can be determined according to actual conditions, for example, 5 minutes, at which time the conflict resolution mechanism is started. The neighboring satellite with a higher degree of coplanarity of the orbits is preferentially selected to reduce the control fluctuation caused by the relative motion of the orbits. The traditional satellite admission priority mainly depends on static indicators such as communication bandwidth and processing capacity, while the present application introduces the dynamic spatial geometric parameter of the degree of coplanarity of the orbits when the admission capacity comprehensive values are similar, to form a multi-dimensional decision model. For example, when the difference between the utilization rates of the computing resources of two neighboring satellites is only 2%, the neighboring satellite with a higher degree of coplanarity of the orbits (such as a coplanarity degree > 90%) can be preferentially selected to avoid the decision ambiguity caused by the similarity of a single indicator. The coplanar orbits mean that the relative positions between the satellites are more stable, and the time for establishing the inter-satellite link can be shortened. This adjustment mechanism makes the satellite admission strategy more suitable for the actual operation environment of the satellite network, and avoids the waste of resources caused by the disconnection between the theoretical model and the physical reality. The signal transmission path between the satellites in the coplanar orbits is shorter and the interference is less. By preferentially selecting the coplanar neighboring satellites, the number of data retransmissions can be reduced, and the success rate of real-time services (such as remote sensing data backhaul) can be improved. The admission of the non-coplanar neighboring satellites may require frequent orbit adjustment, and the present application can reduce such invalid maneuvers and prolong the fuel life of the satellites by preferentially selecting the coplanar neighboring satellites.

[0054] In an embodiment, the method further comprises:

[0055] If it is monitored that the satellite-borne network management node of the third satellite of the first satellite does not meet the satellite admission rules, the last neighboring satellite of the third satellite in the satellite admission priority neighboring satellite set of the first satellite is re-determined as the third satellite;

[0056] A satellite admission instruction is sent to the re-determined satellite-borne network management node of the third satellite.

[0057] In the above embodiment, when it is monitored that the on-board network management node of the third satellite does not meet the management rule, through dynamic updating of the priority neighbor satellite set, the optimal replacement third satellite can be automatically selected after the third satellite fails. The mechanism supports dynamic role replacement in a distributed satellite system.

[0058] In an embodiment, the method further comprises:

[0059] For each first satellite in the management state, according to a second preset period, according to the co-orbit state of the third satellite and the first satellite, the third satellite is re-searched from the management priority neighbor satellite set of the first satellite;

[0060] If the third satellite can be re-searched, a management authority update reminder is sent to an operator;

[0061] If a management authority update instruction sent by the operator is received, an abandonment management instruction is sent to the on-board network management node of the current third satellite, and a request management instruction is sent to the on-board network management node of the re-searched third satellite.

[0062] In the present application, the co-orbit state of the satellite (such as the same orbit plane, orbit height deviation, phase difference, etc.) will change over time due to perturbation, maneuvering and other factors, directly affecting the management efficiency of the third satellite to the first satellite. By periodically evaluating the co-orbit state and finding a new third satellite through a second preset period, it can be ensured that the first satellite always establishes a management relationship with a neighbor satellite with a more optimal co-orbit state. If the management relationship is fixed for a long time, the relative orbital position of the third satellite and the first satellite may deteriorate, resulting in an increase in inter-satellite link maintenance costs. Through the periodic updating mechanism, the management relationship can be dynamically adjusted to a more economical state. Satellite networks involve complex task planning and resource scheduling, and completely automated management switching may ignore global goals due to local optimization. By sending an update reminder to the operator, manual judgment of macro factors such as task priority and system load can be introduced, avoiding risks caused by mechanical switching. The change of the management relationship may affect the business operation of the first satellite. Through the interaction process of the reminder and the instruction, the operator can execute the switching after reconfirming the hardware state, task load and other information of the third satellite, reducing the failure of management caused by the oversight of automated evaluation. When multiple first satellites need to cooperatively execute tasks, a unified management update mechanism can ensure that the state of the third satellite of each satellite is consistent, reducing the collaborative errors caused by differences in management relationships.

[0063] In an embodiment, re-searching the third satellite from the management priority neighbor satellite set of the first satellite according to the co-orbit state of the third satellite and the first satellite comprises:

[0064] If the third satellite is in the same orbit as the first satellite, the satellite in the same orbit with the highest management priority in the management priority neighbor set of the first satellite is found, and if the management priority of the satellite in the same orbit with the highest management priority is higher than that of the third satellite, the satellite in the same orbit with the highest management priority is re-determined as the third satellite;

[0065] If the third satellite is not in the same orbit as the first satellite, and there is a satellite in the same orbit as the first satellite, the satellite in the same orbit with the highest management priority in the management priority neighbor set of the first satellite is re-determined as the third satellite;

[0066] If the third satellite is not in the same orbit as the first satellite, and there is no satellite in the same orbit as the first satellite, if the satellite with the highest management priority in the management priority neighbor set of the first satellite is not the third satellite, the satellite with the highest management priority is re-determined as the third satellite.

[0067] In the present application, there is natural motion synchronization between satellites in the same orbit, and the communication stability, data transmission delay, and orbit maneuver cost of the inter-satellite link are all better than those of cross-orbit satellites. When the third satellite is not in the same orbit as the first satellite, a satellite in the same orbit is preferentially selected as the new third satellite, which can fully exert the synergistic advantages brought by the characteristics of the same orbit and reduce the management loss caused by the difference in orbits. Even among satellites in the same orbit, there are still differences in management capabilities. When the third satellite is in the same orbit as the first satellite, switching is only performed when a higher-priority satellite in the same orbit exists, which can avoid meaningless frequent switching within the same orbit and at the same time ensure that the first satellite is always bound to the optimal third satellite within the same orbit. In a satellite network, the neighbors of the first satellite can include both satellites in the same orbit and satellites in different orbits, and the management adaptability of the two is significantly different. Through three layers of judgment logic, the priority verification of the third satellite in the same orbit, the preference for the same-orbit neighbor when crossing the orbit, and the selection of the highest-priority neighbor when there is no same-orbit satellite, the full coverage of different orbit combination scenarios is realized. For isolated orbit satellites, there can be no same-orbit neighbors. When there is no same-orbit satellite, the selection of the highest-priority neighbor ensures the continuity of the management relationship in such scenarios and avoids the first satellite being in a state of no management due to rigid rules. If no priority verification logic is set, there can be frequent switching when the priority of the same-orbit satellite is slightly higher but the difference in capability is small, which can lead to an explosive increase in inter-satellite signaling interaction and fluctuations in management state. The rule of switching only when the priority of the same-orbit satellite is significantly higher than that of the current third satellite can reduce the number of invalid switches. When the first satellite can only select a cross-orbit neighbor, the selection of the highest-priority neighbor ensures the optimality of the cross-orbit management relationship. At the same time, the logic of switching only when the highest-priority neighbor is not the current third satellite avoids frequent adjustments in the cross-orbit scenario.

[0068] Figure 2For the flowchart of the third satellite re-optimization in the embodiments of the present application, the flowchart can be executed according to the second preset period for each first satellite in the managed state, and the specific steps include:

[0069] S0, judging whether the third satellite is on the same orbit as the first satellite, if yes, entering S1, if no, entering S2;

[0070] S1, selecting the same-orbit satellite of the first satellite from all the neighboring satellites of the first satellite, and entering S11;

[0071] S11, searching for the same-orbit satellite of the first satellite with the highest managed priority from the managed priority neighboring satellite set of the first satellite, and entering S12;

[0072] S12, judging whether the managed priority of the same-orbit satellite with the highest managed priority is higher than that of the third satellite, if yes, entering S13, if no, ending the flowchart;

[0073] S13, re-determining the same-orbit satellite with the highest managed priority as the third satellite, and entering S01;

[0074] S2, judging whether the first satellite has the same-orbit satellite, if yes, entering S21, if no, entering S3;

[0075] S21, re-determining the same-orbit satellite with the highest managed priority in the managed priority neighboring satellite set of the first satellite as the third satellite, and entering S01;

[0076] S3, judging whether the neighboring satellite with the highest managed priority in the managed priority neighboring satellite set of the first satellite is the third satellite, if no, entering S31, if yes, ending the flowchart;

[0077] S31, re-determining the neighboring satellite with the highest managed priority as the third satellite, and entering S01;

[0078] S01, sending the managed right update reminding to the operator;

[0079] S02, judging whether the managed right update instruction sent by the operator is received, if yes, entering S03, if no, ending the flowchart;

[0080] S03, sending the abandonment managed instruction to the on-board network management node of the third satellite, and sending the request managed instruction to the re-determined on-board network management node of the third satellite.

[0081] Figure 3 For the flowchart of another inter-satellite managed method based on the center competition arbitration in the embodiments of the present application, the flowchart is applied to the on-board network management node of the third satellite, and includes:

[0082] Step 301, in response to the failure information of the first satellite, sending a management application to the ground network management system;

[0083] Step 302, receiving the management response fed back by the ground network management system, if the management response includes the consent to management, starting the management of the on-board network equipment of the first satellite;

[0084] The third satellite is the satellite with the highest priority in the management priority neighboring satellite set of the first satellite of the ground network management system and meets the management rule.

[0085] In Figure 3 When the first satellite fails, by sending an application to the ground network management system and determining the third satellite by the ground network management system, even if the satellite that may be out of contact in the original management mode, the on-board network equipment of the satellite can continue to be managed and controlled under the intervention of the third satellite, effectively solving the problem of single-satellite management out of contact. With the help of the ground network management system, the third satellite is determined according to the management priority rule, so that the management resources can be more reasonably allocated. This mode breaks the limitation of relying only on single-satellite management, and can quickly realize relay management of the first satellite through the third satellite such as neighboring satellite, greatly improving the reliability of the whole on-board network equipment management system, reducing various risks caused by management out of contact, such as equipment out of control, service interruption, etc., providing stronger guarantee for the stable operation of on-board network equipment.

[0086] In the embodiment of the application, the first satellite is monitored by its neighboring satellite, and for a satellite, the monitoring steps include:

[0087] Real-time collection of at least one running parameter of all neighboring satellites, and generation of a management demand signal of the neighboring satellite when at least one running parameter of a neighboring satellite exceeds the corresponding preset threshold;

[0088] Judging whether the communication link of the neighboring satellite generating the management demand signal is invalid; determining the neighboring satellite whose communication link is not invalid as the first satellite that needs to be managed.

[0089] The running parameter includes but is not limited to the working state of the on-board network equipment (such as hardware failure, software exception, communication interruption, etc.), the attitude control accuracy of the satellite itself, the energy system stability, etc. If it is detected that the communication link is continuously interrupted and exceeds the set time length (such as 10 minutes), or the link quality is lower than the minimum communication standard (such as the data packet loss rate exceeds 30%), the communication link is determined to be invalid.

[0090] In an embodiment, the method further comprises:

[0091] After receiving the abandonment management instruction, abandoning the management of the on-board network equipment of the first satellite;

[0092] After receiving the request for management instruction, the management of the on-board network equipment of the first satellite is started.

[0093] In an embodiment, the method further comprises:

[0094] If the management response of the ground network management system is not received within the first preset time length for a continuous first preset number of times, and the third satellite can be connected, a management query request is sent to the on-board network management node of the third satellite, and the management response including the consent to management is received.

[0095] In response to the management query request of the on-board network management node of the second satellite, a management response including the consent to management is fed back to the on-board network management node of the second satellite.

[0096] The above embodiment is aimed at the case that the ground network management system cannot communicate with the satellite due to various reasons such as failure, at this time, the first satellite is faulty and needs to be managed, then a third satellite can be determined from the neighboring satellites of the first satellite to be managed and controlled, and the determination method is to determine the management priority neighboring satellite set according to the preset management priority neighboring satellite set in each neighboring satellite.

[0097] Figure 4 The flowchart of another inter-satellite management method based on center competition arbitration in the embodiments of the present application is applied to the on-board network management node of the second satellite, and comprises:

[0098] Step 401, in response to the failure information of the first satellite, a management application is sent to the ground network management system;

[0099] Step 402, the management response fed back by the ground network management system is received, if the management response includes the rejection of management, the management result in the management response is recorded;

[0100] The second satellite is a neighboring satellite of the first satellite except the third satellite, and the third satellite is the satellite with the highest priority in the management priority neighboring satellite set of the first satellite of the ground network management system and meets the management rule.

[0101] In an embodiment, the method further comprises:

[0102] If the management response of the ground network management system is not received within the first preset time length for a continuous first preset number of times, and the third satellite can be connected, a management query request is sent to the on-board network management node of the third satellite, and the management response including the consent to management is received.

[0103] The above embodiment is directed to the case that the ground network management system cannot communicate with the satellite due to various reasons such as failure, and the first satellite needs to be managed, and a third satellite is determined from the neighboring satellites of the first satellite to be managed and controlled, and the second satellite needs to send a management query request to the on-board network management node of the third satellite, and wait to receive a management response including an agreement to manage, so as to realize information sharing.

[0104] Three specific embodiments are given below to illustrate the specific application of the method proposed in the embodiment of the application.

[0105] In an embodiment of the application, scenario 1 is that all the neighboring satellites of the first satellite that are ready to be managed are running normally

[0106] All the on-board network management nodes of the neighboring satellites running normally send a management application to the ground network management system, and the ground network management system determines the satellite with the highest priority in the management priority neighboring satellite set of the first satellite as the third satellite.

[0107] Figure 5 The third satellite is determined by the ground network management system in the embodiment of the application.

At the same time, the decision is made based on the preset priority rule set, reducing the uncertainty caused by human intervention, ensuring that the selection of the third satellite meets the optimal standard, and improving the accuracy of the decision. Optimizing inter-satellite resource allocation and collaboration efficiency: sending a response agreeing to incorporate to the on-board network management node of the third satellite, and sending a response rejecting incorporation and the result to the on-board network management node of other neighbor satellites, the role of each neighbor satellite can be clearly positioned. This can avoid resource competition and conflict caused by multiple neighbor satellites trying to incorporate the first satellite at the same time, reasonably allocate inter-satellite resources, enable the third satellite to concentrate resources to effectively manage the first satellite, and improve the overall efficiency of inter-satellite collaborative management. The entire incorporation process is centrally decided by the ground network management system, forming a standardized operation process. Each neighbor satellite performs corresponding operations according to the clear incorporation response, reducing the possibility of process confusion. In addition, the response rejecting incorporation includes the incorporation result, so that each neighbor satellite can clearly understand the information of the third satellite, and combined with the recording mechanism, a complete incorporation process record chain can be constructed, providing traceable basis for subsequent problem troubleshooting and process optimization. Quickly and accurately determining the third satellite and starting the incorporation can timely fill the possible management gap of the first satellite, avoiding the risk of single-satellite management disconnection. At the same time, the clear inter-satellite division of labor and collaboration mechanism improves the ability of the satellite network to respond to abnormal situations, ensures the continuity of the management of the on-board network equipment, and further enhances the stability and reliability of the entire satellite network, laying a solid foundation for achieving the global wide-area intelligent connection service goal.
