[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Figure 1 A multi-state ground and space communication system in a preferred embodiment of the present invention. Figure 1 As shown, it includes: a plurality of communication devices 111, 112, 113, at least one fixed base station 12, at least one emergency communication vehicle 13, and at least one satellite 14. The fixed base station 12 has a built-in first communication platform server 121, the emergency communication vehicle 13 has a built-in second communication platform server 131, and the satellite 14 has a built-in third communication platform server 141. It should be understood that the communication system of the present invention may also include more fixed base stations, more emergency communication vehicles, and more satellites, with each fixed base station, emergency communication vehicle, or satellite having a built-in communication platform server. For ease of explanation, only one fixed base station 12, one emergency communication vehicle 13, and one satellite 14 are used as examples.

[0031] The communication devices 111 , 112 , and 113 may be various terminal devices, including but not limited to smartphones, tablet computers, laptop computers, desktop computers, wearable devices (such as smart watches), IoT devices, in-vehicle communication systems, and professional military or emergency communication equipment such as satellite phones and tactical radios. These communication devices 111 , 112 , and 113 are equipped with appropriate hardware, such as a processor, memory, a communication module (including a cellular network module, a Wi-Fi module, a Bluetooth module, a satellite communication module, etc.), and a user interface (such as a touch screen, a keyboard, a microphone, a speaker, etc.).

[0032] The fixed base station 12 is typically a fixed-location communications facility and may include a traditional cellular network base station, a 5G base station, a wireless network access point, etc. The hardware components of the fixed base station 12 may include a high-power transmitter, a receiver, a signal processing unit, network switching equipment, a power supply system (including a backup power supply), a cooling system, etc. The fixed base station 12 has a built-in first communication platform server 121. The first communication platform server 121 can be a high-performance computer system that may include multiple server racks, a storage array, a load balancer, etc.

[0033] The emergency communication vehicle 13 is a mobile communication facility, typically designed to operate in a variety of terrains and environments. It may be a modified large truck or a specialized vehicle equipped with a deployable antenna system, satellite communication equipment, various wireless communication systems (such as LTE, 5G, shortwave, ultra-shortwave, etc.), a generator, an air conditioning system, and more. The emergency communication vehicle 13 has a built-in second communication platform server 131, which may be a small but high-performance computer system with significant processing power and storage capacity.

[0034] Satellite 14 can be a geosynchronous orbit satellite, a medium orbit satellite, or a low orbit satellite, and is equipped with a multi-band communication system, solar panels, an attitude control system, a thermal control system, etc. Satellite 14 has a built-in third communication platform server 141, which can be a computer system specially designed for space environments and has high reliability and radiation resistance.

[0035] In the communication system of the present invention, at least one of the first communication platform server 121, the second communication platform server 131, or the third communication platform server 141 can receive a status signal 50. The status signal is used to determine whether the current communication status is in a first state period or a second state period. This status signal 50 may be issued by one or more external devices 51, such as a system control center, government department, or military command outside the communication system.

[0036] The issuance of the status signal 50 may be based on various conditions, such as regional security conditions, natural disaster alerts, major public events, cybersecurity threat levels, etc. The following are some examples of differentiating the first and second status periods under different circumstances:

[0037] Natural disaster status:

[0038] The first phase: normal weather conditions

[0039] Second stage: when natural disasters such as typhoons, earthquakes, floods, and tsunamis occur

[0040] Public Health Events:

[0041] The first stage: daily health status

[0042] Second stage: epidemic outbreak, biological crisis, etc.

[0043] Network security level:

[0044] The first state: normal network security state

[0045] Second stage: when threatened by large-scale cyber attacks or data leaks

[0046] Environmental pollution incidents:

[0047] The first state: normal environmental conditions

[0048] Second stage: when serious air pollution, water pollution or nuclear leakage occurs

[0049] Social security situation:

[0050] The first stage: the period of social stability

[0051] Second stage: when large-scale social unrest or terrorist attacks occur

[0052] Next, the communication system selects an appropriate communication mode based on the received status signal 50. When the status signal 50 indicates the current state is the first state, the system activates the first communication mode. In this mode, the plurality of communication devices 111, 112, and 113 are interconnected and communicate with each other via the first communication platform server 121 of the fixed base station 12.

[0053] However, when the status signal 50 indicates that the system is currently in the second state, the system switches to the second communication mode. In this mode, the plurality of communication devices 111, 112, and 113 selectively connect to and communicate with each other through the second communication platform server 131 of the emergency communication vehicle 13 or the third communication platform server 141 of the satellite 14. For example, if the plurality of communication devices 111, 112, and 113 can connect to the second communication platform server 131 of the emergency communication vehicle 13, they will connect to and communicate with each other in this manner. If they cannot connect to the second communication platform server 131 of the emergency communication vehicle 13, they will instead connect to and communicate with each other through the third communication platform server 141 of the satellite 14.

[0054] In addition, to ensure data synchronization between different communication platform servers 121, 131, and 141, a synchronization frequency value can also be set in this system. The synchronization frequency value is used to control the frequency of data synchronization between the first communication platform server 121, the second communication platform server 131, and the third communication platform server 141. In the present invention, each of the first, second, and third communication platform servers 121, 131, and 141 can be set with a synchronization frequency value and then synchronize data with the other communication platform servers based on the synchronization frequency value.

[0055] The setting of the synchronization frequency value is not fixed, but can be dynamically adjusted based on multiple parameters. These parameters include: the network connection status between the communication platform servers, the amount of data changes on each communication platform server, the current processing load of each communication platform server, and the amount of data of different data types. For example, when the network connection is good, the system may increase the synchronization frequency; when the processing load of a server is high, the system may reduce the synchronization frequency with the server. For important or frequently changing data types (such as text data, voice data, image data, and video data), the system may set a higher synchronization priority.

[0056] Finally, the system synchronizes data between the first communication platform server 121, the second communication platform server 131, and the third communication platform server 141 according to the set synchronization frequency value. This ensures that no matter which platform the communication devices 111, 112, and 113 communicate through, all important data can be updated in a timely manner across the platforms.

[0057] Data synchronization can involve a variety of techniques. For example, incremental synchronization can be used to transmit only changed data, reducing network overhead. Multi-version concurrency control (MVCC) can also be used to handle concurrent updates. For synchronizing large amounts of data, batch synchronization may be used when the network load is low. Under poor network conditions, compression or incremental encoding may be used to reduce the amount of data transmitted. Furthermore, the system may use distributed database technologies such as Apache Cassandra or CockroachDB to achieve cross-platform data consistency.

[0058] Figure 2 FIG. 1 is a flow chart of a multi-state ground-space communication method in a preferred embodiment of the present invention. Figure 2 As shown, it includes:

[0059] In step 101, a plurality of communication devices 111, 112, and 113, at least one fixed base station 12, at least one emergency communication vehicle 13, and at least one satellite 14 are provided. The fixed base station 12 has a built-in first communication platform server 121, the emergency communication vehicle 13 has a built-in second communication platform server 131, and the satellite 14 has a built-in third communication platform server 141.

[0060] Step 102 receives a status signal transmitted from an external device. The status signal is used to determine whether the current communication status is a first state period or a second state period. The external device may be issued by a system control center, a government department, or a military command department, but the present invention is not limited to this. The status signal is used to determine whether the current communication status is a first state period or a second state period. This status distinction may be based on various conditions, such as regional security conditions, natural disaster alerts, major public events, network security threat levels, etc. In the present invention, at least one of the first communication platform server 121, the second communication platform server 131, or the third communication platform server 141 may receive and process this status signal, and then inform the other communication platform servers whether the current communication status is a first state period or a second state period.

[0061] In step 103, during the first state, multiple communication devices 111, 112, and 113 are interconnected and communicate with each other via the first communication platform server 121 of the fixed base station 12. In this mode, the multiple communication devices 111, 112, and 113 are interconnected via the first communication platform server 121 of the fixed base station 12. Communication activities such as data transmission, voice calls, and video conferencing between the multiple communication devices 111, 112, and 113 are routed and processed by the first communication platform server 121 of the fixed base station 12.

[0062] Step 104: During the second state, multiple communication devices 111, 112, and 113 are selectively interconnected and communicated through the second communication platform server 131 of the emergency communication vehicle 13 or the third communication platform server 141 of the satellite 14. In one embodiment of the present invention, the system first attempts to interconnect and communicate multiple communication devices 111, 112, and 113 through the second communication platform server 131 of the emergency communication vehicle 13. If this connection cannot be established or maintained, the system automatically switches to communicating with the multiple communication devices 111, 112, and 113 through the third communication platform server 141 of the satellite 14. This flexible switching mechanism ensures the continued operation of the communication system in various extreme situations (such as natural disasters and public health incidents).

[0063] Step 105 : Setting a synchronization frequency value for controlling the frequency of data synchronization between the first communication platform server 121 , the second communication platform server 131 , and the third communication platform server 141 .

[0064] To ensure data consistency across different communication platforms, the system of the present invention can set a synchronization frequency value to control the frequency of data synchronization between the first communication platform server 121, the second communication platform server 131, and the third communication platform server 141. The synchronization frequency value is not fixed but can be dynamically adjusted based on multiple parameters, including: the network connection status between the communication platform servers, the amount of data change on each communication platform server, the current processing load of each communication platform server, and the amount of data of different data types.

[0065] In the present invention, each communication platform server can be configured with a synchronization frequency value or receive synchronization frequency values ​​transmitted by other communication platform servers, and perform data synchronization operations accordingly. Data synchronization may adopt various technologies, such as incremental synchronization, multi-version concurrency control (MVCC), batch synchronization, compression technology, etc., to ensure efficient synchronization under various network conditions.

[0066] Figure 3 FIG. 1 is a flow chart of a communication method of a communication platform server in a preferred embodiment of the present invention. Figure 3 As shown, it includes:

[0067] In step 201 , a status signal is received from an external device to determine whether the current state is a first state period or a second state period.

[0068] Step 202 , in a first state, when the communication platform server is configured in a fixed base station, a plurality of external communication devices are allowed to connect to and communicate with each other through the communication platform server.

[0069] Step 203 , in the second state, when the communication platform server is configured in an emergency communication vehicle or a satellite, it allows a plurality of external communication devices to be linked and communicated with each other through the communication platform server.

[0070] Step 204 , setting a synchronization frequency value to control the frequency of data synchronization between the communication platform server and other communication platform servers.

[0071] The multi-state ground-to-space communication system and communication method proposed in this invention provide a multi-state communication method that can adapt to different situations. It not only provides efficient communication services under normal circumstances, but also can quickly switch to alternative communication methods in emergency situations, while ensuring the consistency and real-time nature of information through an intelligent data synchronization mechanism. This flexibility and reliability make the system particularly suitable for scenarios that require maintaining stable communications in various complex environments, such as military communications, disaster relief, large-scale event security, and critical infrastructure protection. The system design takes into account different usage scenarios and possible failure modes, ensuring the continuity and reliability of communications, while also leaving room for future technological upgrades and expansion.
