Description

Technical Field

[0001] The present invention relates to the technical field of satellite communications, and in particular to a management method for a satellite communication networking central station and a satellite communication network. Background Art

[0002] Satellite communication is an important emergency communication method because it is not restricted by geographical location or base stations of ground network operators, and its communication quality is not affected by severe natural disasters such as earthquakes. When facing major disasters, the communication reliability of the command center (central station) is crucial to cope with high-frequency and random communication needs.

[0003] Currently, most satellite communication networks on the market require daily maintenance inspections by station operators, and cannot achieve real-time monitoring, respond to unexpected equipment failures, service system anomalies, or sudden failure of a single station, and cannot ensure that the entire communication network is always in normal working order to respond to unexpected communication needs. Therefore, the need to build a highly available satellite communication network has become an urgent problem to be solved in the industry. Summary of the invention

[0004] Purpose of the invention: The present invention aims to propose a management method for a satellite communication networking central station and a satellite communication network to improve the reliability of the satellite communication network.

[0006] As an optional implementation manner of the method of the first aspect, the method further includes: If the processor is currently in the active state, and receives information that the working state of other processors in the target central station is the active state, if the device number of other processors is smaller than its own device number, it switches its own working state to the standby state; otherwise, it maintains its own working state as the active state.

[0007] As an optional implementation manner of the method of the first aspect, the method further includes: When there is a processor in the master state in the target central station, the processor in the master state monitors and controls other networking service devices in the target central station in real time.

[0008] As an optional implementation manner of the method of the first aspect, the method further includes: assigning unique station numbers to the plurality of target central stations; The target central station initializes its own station role as a standby role after being enabled; The processor in the master state of the target central station regularly broadcasts its own station role and station number between stations, and receives the station role and station number broadcasted by other target central stations to complete the information synchronization between stations; If the target central station receives that the station role of the other target central station is the active role, the station role of the current station is kept as the standby role; If the target central station receives that the station roles of other target central stations are all standby roles and the station number of the current station is the smallest, the station role of the current station is switched to the active role.

[0009] Furthermore, the method further comprises: If the target central station is currently in the active role, and when receiving the station role of other target central stations as the active role, if the station number of other target central stations is smaller than the station number of this station, the station role of this station is switched to the standby role; otherwise, the station role of this station is kept as the active role.

[0010] Furthermore, the method further comprises: In the target central station, the remaining networking service devices maintain a heartbeat connection with the processor in the master state, and the processor in the master state maintains a list of networking service information within the station; If the processor in the master state does not receive the heartbeat connection maintenance information of a certain networking service device within N consecutive heartbeat cycles, the networking service device is removed from the in-station networking service information list.

[0011] Furthermore, the method further comprises: In the target central station, the processor in the active state periodically checks whether the networking service devices in the networking service information list within the station meet the minimum functional guarantee requirements.

The singular forms "a", "the" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates otherwise.

[0022] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Therefore, it should be recognized by those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0023] It should be noted that: in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the steps included in the method may be more or less than those described in this specification. In addition, a single step described in this specification may be decomposed into multiple steps for description in other embodiments; and multiple steps described in this specification may be combined into a single step for description in other embodiments.

[0024] This manual aims to address the problem that existing satellite communication networks have poor reliability and are difficult to deal with abnormal situations such as sudden equipment failures, service system abnormalities or sudden failure of a single station, and proposes a management method for a satellite communication networking central station and a satellite communication network.

[0025] The following will combine the drawings and specific embodiments of the specification to further explain in detail a management method for a satellite communication networking central station and a satellite communication network described in one or more embodiments of this specification, but this detailed description does not constitute a limitation on the embodiments of this specification.

[0026] Please refer to Figure 1 , Figure 1 The following is a schematic diagram showing the structure of a satellite communication network. Figure 1The satellite communication network shown includes multiple target central stations, which are used to provide satellite communication networking services. The target central stations interact with each other through inter-station dedicated lines. Each target central station includes multiple processors, which realize intra-station data interaction through the switches in the station.

[0027] based on Figure 1 The satellite communication network shown in the figure, this embodiment provides a management method for a satellite communication networking central station, the method including an intra-station management scheme and an inter-station management scheme.

[0028] Please refer to Figure 2 , Figure 2 The following schematically shows the switching control flow chart of the master and standby processors (hereinafter referred to as MSW) in the station. Figure 2 As shown, the site management solution includes the following steps: S11: Allocate unique equipment numbers (hereinafter referred to as MSW numbers) to multiple MSWs of the target central station.

[0029] S12: After the MSW is started, it initializes its own working state to the standby state, and periodically exchanges working states with other MSWs in the target central station.

[0030] S13: If the MSW receives that the working state of other MSWs in the target central station is the active state, the MSW maintains its own working state as the standby state.

[0031] S14: If the MSW receives that the working state of other MSWs in the target central station is the standby state and its own equipment number is the smallest, it switches its own working state to the active state.

[0032] S15: If the MSW is currently in the active state, and receives information that the working state of other MSWs in the target central station is the active state, if the equipment number of other MSWs is smaller than its own equipment number, it switches its own working state to the standby state; otherwise, it maintains its own working state as the active state.

[0033] In the above process, after the MSW is started, it sends station information notifications at regular intervals, reports its own MSW number and MSW status to other MSWs in the station, receives the MSW number and MSW status information sent by other MSWs in the station, and stores the MSW number and MSW status of all MSWs in the station in the MSW information list in the station.

[0034] Each MSW adjusts its own working status according to the MSW information list in the station.

[0035] When there is an MSW in the master state in the target central station, the MSW in the master state monitors and controls other networking service devices in the target central station in real time. Specifically, after the networking service devices other than the MSW in the target central station are started, they will receive the in-station information notification sent by the MSW in the master state. At this time, the networking service device needs to immediately send a startup report to it. After receiving the response, it executes a periodic heartbeat connection to maintain the connection with the MSW in the master state. The MSW in the master state dynamically generates and maintains an in-station networking service information list based on the startup report of the in-station networking service device. The MSW in the master state can subsequently determine the status of the in-station networking service device based on the periodic heartbeat keep-alive. For example, if the heartbeat maintenance of the networking service device is not received within three consecutive heartbeat cycles, the record of the networking service device will be removed from the in-station networking service information list.

[0036] In addition, the active MSW can also regularly check whether the currently started networking services meet the service categories and quantities required for minimum functional assurance, and execute the station failure control process. Figure 3 As shown, in the target central station, the MSW in the active state periodically checks whether the networking service equipment in the networking service information list in the station meets the minimum functional guarantee requirements. If not, the station role of this station is changed to a disabled role, and its own station role and station number are broadcast between stations. If the current station role of the target central station is a disabled role, and the MSW in the active state of the target central station checks whether the networking service equipment in the networking service information list in the current station meets the minimum functional guarantee requirements, the station role of this station is switched to a standby role.

[0037] Please refer to Figure 4 , Figure 4 The following schematically shows the control flow chart of the main and standby switching between stations. Figure 4 As shown, the inter-station management solution includes the following steps: S21: Allocate unique station numbers to multiple target central stations.

[0038] S22: After being enabled, the target central station initializes its own station role to a standby role.

[0039] S23: The processor in the master state of the target central station regularly broadcasts its own station role and station number between stations, and receives the station roles and station numbers broadcast by other target central stations, thereby completing information synchronization between stations.

[0040] S24: If the target central station receives that the station role of the other target central station is the active role, the station role of the current station is kept as the standby role.

[0041] S25: If the target central station receives information that the station roles of other target central stations are all standby roles, and the station number of the current station is the smallest, the target central station switches its own station role to the active role.

[0042] S26: If the target central station is currently in the active role, and when receiving the station role of other target central stations as the active role, if the station number of other target central stations is smaller than the station number of this station, switch the station role of this station to the standby role; otherwise, keep the station role of this station as the active role.

[0043] In a satellite communication network consisting of multiple target central stations, the MSW in the active state among the target central stations with the active role monitors and controls the working status of other target central stations in real time. For example, the MSW can issue a status configuration instruction to configure the active and standby status of each networking service device in the network. The networking service device configured in the active state will enter the working state from the waiting state. The networking service device receives the status configuration instruction, enters the corresponding state, and completes the networking task.

[0044] The above is a management method for a satellite communication networking central station described in this embodiment. This method introduces the concepts of service machine master-slave and station master-slave in satellite communication networking, that is, system services in a central station must meet master-slave control, and multiple remote central stations complete station-level master-slave control together, thereby realizing a highly available satellite communication network. Through the automatic switching of the main processor and the control of other networking service equipment in the station, real-time monitoring and fault alarm of the system service status in the station can be realized, and the switching of system services in the station can be completed automatically. At the same time, the method can monitor the minimum guarantee capacity in a single station. When the main station cannot provide the minimum guarantee capacity requirements, it automatically switches to an idle station with guarantee capacity, thereby continuously ensuring the normal operation of the satellite network. Corresponding to the above-mentioned management method of the central station of the satellite communication network, this embodiment also provides a satellite communication network, which adopts the above-mentioned management method of the central station of the satellite communication network to manage the central station in the network.

In particular, for the device embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
