[0002] Recently, disasters such as fires and earthquakes have occurred frequently. After each disaster, whether an emergency command and communication system can be provided in a timely manner plays an important role in disaster relief work.

[0003] At present, the satellite communication system used for emergency rescue usually requires terminals deployed in the disaster area to transmit the collected IoT data via satellite Internet to the gateway station, which will process the IoT data. Since the gateway station needs to process the IoT data of all terminals transmitted via satellite Internet, it is difficult to ensure the timeliness of IoT data transmission in the disaster area. In addition, the deployment location of the gateway station is fixed and cannot be moved as the location of the disaster area changes. This makes it impossible to guarantee the communication distance between the gateway station and the disaster area, which will further reduce the timeliness of IoT data transmission in the disaster area.

[0062] In order to ensure the timeliness of terminal data transmission and further speed up the processing speed of terminal data, the embodiments of the present application provide a satellite communication system, method, device, electronic equipment and storage medium.

[0063] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings of the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application, and the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0064] In order to facilitate understanding of the present application, among the technical terms involved in the present application:

[0065] Satellite Internet refers to an Internet based on satellite communication. It is a network composed of a certain amount of satellites to radiate the globe. Satellite Internet is mainly composed of low-orbit satellite constellations, which has the advantages of low delay, low orbit, wide coverage, high bandwidth, low cost, large capacity, low power consumption, etc.

[0066] Gateway station is a device that provides an interface between satellite communication system and ground fixed communication network and ground mobile communication network, and realizes interconnection. It is an indispensable link in satellite Internet communication. In order to successfully use satellite Internet, in addition to using a satellite terminal to connect to a satellite, a device is also needed to transfer the data of the satellite to the ground public network. This device is a gateway station. It is responsible for communication with satellites within the visual range through a feeder link, distribution and collection of satellite communication service data, and can complete data exchange within the satellite communication network and data routing of external networks, while having network management and operation control functions, responsible for completing network resource scheduling, system equipment management and user service management.

[0067] Portable station is a kind of satellite communication station, a set of relatively light and convenient to install portable equipment for terminal and satellite communication, which can download data from satellite and upload data to satellite, can provide two-way broadband transmission channel, provide high-quality voice, data and real-time image integrated services. Specifically, portable station can be portable gateway station, vehicle-mounted gateway station, ship-mounted gateway station and light gateway station, which can be adapted to various platforms such as field, vehicle-mounted and ship-mounted.

[0068] Terminal: a device that can provide voice and / or data connectivity to a user. For example, terminal devices include handheld devices with wireless connection functionality, vehicle-mounted devices, etc. At present, terminal devices can be Internet of Things terminals, such as satellite phones, intelligent cameras, temperature and humidity sensors, individual image transmission, etc., and can also be mobile communication terminals, convergence terminals, convergence gateways, high-low orbit convergence terminals, edge computing terminals, broadband terminals, and satellite-ground convergence terminals, etc. Through a user link, the terminal communicates with a satellite served by the terminal, mainly for sending and responding to communication requests, supporting handheld, vehicle-mounted, ship-mounted, airborne, etc. Various forms, supporting data and / or voice services. Generally, when the terminal is a satellite phone, the corresponding Internet of Things data is voice data, when the terminal is an intelligent camera, the corresponding Internet of Things data is image data, when the terminal is a temperature and humidity sensor, the corresponding Internet of Things data is temperature and humidity data, and other terminals are similar, which will not be repeated here.

[0069] The operation service platform is a platform deployed in the gateway station for completing functions such as service processing, routing exchange, and mobility management, and providing interconnection and interworking with other networks on the ground. The system operation service platform is used to complete the special network configuration through overall planning, divide the network slices by the core network, and finally feed back the special network resources to the network management platform.

[0070] The network management platform is a platform deployed in the portable station for completing functions such as service processing, routing exchange, and mobility management. The system network service platform is used to apply for special network resources from the operation service platform, complete the allocation, scheduling, and dynamic management of special network resources of each terminal, ensure the reasonable use of resources, and at the same time, be responsible for the dynamic management and allocation of resource parameters such as network entry, network exit, activation state, and priority of all terminals in the special network.

[0071] The small core network is a small network management hub similar to the core network, used for the execution work after the allocation, scheduling, and dynamic management of special network resources of each terminal by the network management platform, and the dynamic management and allocation of resource parameters such as network entry, network exit, activation state, and priority of all terminals in the special network. In addition, the Internet of Things data is also transmitted to the data service platform after being decoded by the small core network.

[0072] The small access network is a network management hub deployed between the portable station and the small core network, used for authenticating the terminal during the transmission of Internet of Things data by the terminal.

[0073] Figure 1 An architecture schematic diagram of a satellite communication system provided by the embodiment of the present application includes a network management platform and a portable station.

[0074] The network management platform is configured to acquire a private network demand of a specified area, send the private network demand to the portable station, receive private network resources sent by the portable station, acquire an access demand of each target terminal in the specified area, and allocate private network resources for the target terminal from currently available private network resources based on the access demand, wherein the allocated private network resources are used to access the target terminal to the private network. Here, the specified area can be a city, a community, a street, a mountainous area, a forest, or the like, the private network demand includes information such as bandwidth, area, and time, and the access demand includes information such as service demand of the terminal, required bandwidth, rate, and priority.

[0075] The portable station is configured to send the private network demand to the operation service platform through the satellite Internet to trigger the operation service platform to construct the private network, receive private network resources sent by the operation service platform, and send the private network resources to the network management platform. Here, the process of constructing the private network includes a process in which the operation service platform plans and allocates network resources based on the private network demand, and a process in which the operation service platform calls a core network interface to complete network slice division configuration. After the construction of the private network is completed, the private network resources corresponding to the private network demand are obtained. Generally, the private network resources only serve the specified area corresponding to the private network demand, and the private network resources include bandwidth resources and rate.

[0076] In some embodiments, the network management platform can send the private network demand to the portable station through a small core network and a small access network, and correspondingly, the network management platform can receive the private network resources sent by the portable station through the small access network and the small core network.

[0077] In this way, the terminal accessing the private network can perform data transmission in the constructed private network, realizes local closed loop of data, and guarantees timeliness of terminal data. Meanwhile, the portable station is quickly built and flexibly deployed, and the portable station built in the specified area further facilitates timeliness of Internet of Things data transmission, and thus speeds up processing speed of Internet of Things data.

[0078] In specific implementation, the network management platform is further configured to, if it is determined that the available private network resources cannot meet the access demand of the target terminal, select a terminal meeting a resource recycling condition from terminals accessing the private network, recycle at least part of private network resources of the terminal meeting the resource recycling condition, and allocate private network resources for the target terminal based on the available private network resources and the recycled private network resources.

[0079] Generally, after private network resources are allocated to each terminal, there are still some private network resources left for accessing new terminals. The resource recycling condition can be bandwidth redundancy, inactivation, low priority, or the like.

[0080] Suppose the target terminal is terminal A, when terminal A needs to access the private network with a bandwidth of 40 Mbps, and the bandwidth of the available private network resource is 35 Mbps at this time, the current available bandwidth cannot meet the access requirement of terminal A, then terminal B that meets the resource recycling condition can be selected from the terminals that have accessed the private network, and it is known that terminal B needs a bandwidth of 20 Mbps, and the actual bandwidth used by terminal B is 30 Mbps, at this time, 5-10 Mbps can be recycled from terminal B while still ensuring the normal use of terminal B, and the recycled 5-10 Mbps and the redundant 35 Mbps are allocated to terminal A for use.

[0081] In specific implementation, the network management platform is further configured to re-apply for allocation of private network resources if no terminal that meets the resource recycling condition can be selected from the terminals that have accessed the private network.

[0082] For example, terminal A needs to access the private network, and the required bandwidth is 40 Mbps, but at this time there is no available private network resource and no terminal that can recycle resources, at this time the private network resource can be re-applied to the operation service platform according to the current private network demand.

[0083] In some embodiments, the satellite communication system further comprises a data service platform, wherein:

[0084] The portable station is further configured to receive the Internet of Things data sent by the target terminal through the satellite Internet after the target terminal accesses the private network, and send the Internet of Things data of the target terminal to the data service platform.

[0085] In specific implementation, after receiving the Internet of Things data sent by the target terminal through the satellite Internet, the Internet of Things data of the target terminal can be sent to the small access network, the target terminal is authenticated by the small access network, after the authentication is passed, the Internet of Things data of the target terminal is sent to the small core network, the Internet of Things data of the target terminal is decoded by the small core network, and the decoded Internet of Things data of the target terminal is sent to the data service platform, wherein the Internet of Things data of the target terminal can be any one of image, voice, temperature and humidity, video, positioning data.

[0086] The data service platform is configured to visually analyze the Internet of Things data of each target terminal to obtain visual data, and output the visual data.

[0087] Taking a fire rescue scene as an example, the output visual data can be a fire spread area map, a rescue personnel geographic position distribution map, etc., and the visual data is used for the personnel in the command center to conduct next disaster rescue command and processing.

[0088] In some embodiments, the network management platform is further configured to obtain a terminal identifier of a terminal to be taken over located outside a specified area, and send a terminal takeover request containing the terminal identifier to the portable station.

[0089] In a specific implementation, after obtaining the terminal identifier of the terminal to be taken over located outside the specified area, the network management platform can send a terminal taking-over request carrying the terminal identifier of the terminal to be taken over to the small core network, and then to the small access network, and finally the small access network sends the terminal taking-over request to the portable station and stores the terminal identifier of the terminal to be taken over in the terminal identifier set of the authorized terminal.

[0090] The portable station is also configured to send the terminal taking-over request to the operation service platform through the satellite Internet, receive the Internet of Things data of the terminal to be taken over corresponding to the terminal identifier sent by the operation service platform, and send the Internet of Things data of the terminal to be taken over to the data service platform.

[0091] In a specific implementation, when the portable station sends the Internet of Things data of any terminal to be taken over to the data service platform, the portable station can first send the Internet of Things data of the terminal to be taken over to the small access network, and the small access network judges whether the terminal identifier of the terminal to be taken over is in the stored terminal identifier set. If it exists, it means that the terminal to be taken over is authenticated, and then the Internet of Things data of the terminal to be taken over is sent to the small core network, and the small core network decodes the Internet of Things data of the terminal to be taken over and sends the decoded Internet of Things data to the data service platform. In this way, the terminal to be taken over does not need to occupy the private network resources of the specified area, and temporary management and Internet of Things data acquisition of the terminal to be taken over can also be realized.

[0092] The data service platform is configured to visually analyze the Internet of Things data of each target terminal and the Internet of Things data of the terminal to be taken over.

[0093] In this way, the Internet of Things data of the terminal to be taken over outside the specified area can also be obtained without occupying the private network resources of the specified area, which is beneficial for the data service platform to obtain more comprehensive Internet of Things data, and then more comprehensive visual data can be output.

[0094] In some embodiments, the network management platform is also configured to send a private network resource recycling request for the specified area to the portable station when it is determined that all terminals accessed to the private network are in an inactive state, and the portable station sends the private network resource recycling request to the operation service platform through the satellite Internet to trigger the operation service platform to recycle the private network resources of the specified area.

[0095] Thus, by using the characteristics of rapid installation and flexible deployment of the portable station, the satellite communication system can be established near any designated area requiring a private network service, and the terminals in the designated area do not have to share a gateway station with the terminals outside the designated area, thereby reducing the data processing pressure of the gateway station and improving the data processing speed. Meanwhile, the deployment of the portable station near the designated area also shortens the transmission distance of the Internet of Things data, thereby ensuring the timeliness of the Internet of Things data transmission, which further improves the Internet of Things data processing speed. In addition, the terminals outside the designated area can also be taken over for temporary management, and when the designated area does not require private network resources, the private network resources can also be applied to the operation service platform for recycling, which is relatively good in flexibility.

[0096] Figure 2 An interactive flowchart of a satellite communication system is provided for the embodiments of the present application, and the method comprises the following steps.

[0097] In step 201, the network management platform sends the acquired private network demand of the designated area to the portable station.

[0098] In step 202, the portable station sends the private network demand to the operation service platform through the satellite Internet.

[0099] In step 203, the operation service platform constructs a private network based on the private network demand.

[0100] In step 204, the operation service platform sends the private network resources to the portable station.

[0101] In step 205, the portable station sends the private network resources to the network management platform.

[0102] In step 206, the network management platform acquires the access demand of each target terminal in the designated area.

[0103] In step 207, the network management platform determines whether the current available private network resources meet the access demand of the target terminal based on the access demand, and if yes, proceeds to step 208, and if no, proceeds to step 211.

[0104] In step 208, the network management platform allocates private network resources for the target terminal from the current available private network resources.

[0105] In step 209, the network management platform sends the allocated private network resource information to the target terminal.

[0106] In step 210, the target terminal accesses the private network based on the allocated private network resources.

[0107] In step 211, the network management platform determines whether there is a terminal meeting the resource recycling condition among the terminals accessing the private network, and if yes, proceeds to step 212, and if no, proceeds to step 213.

[0108] In step 212, the network management platform reclaims at least part of the private network resources of the terminal that meets the resource reclaim conditions, and allocates private network resources to the target terminal based on the available private network resources and the reclaimed private network resources.

[0109] In step 213, the network management platform re-applies to the operation service platform for allocation of private network resources.

[0110] In step 214, the target terminal sends the IoT data to the portable station via satellite Internet.

[0111] In step 215, the portable station sends the IoT data of the target terminal to the data service platform.

[0112] In step 216, the data service platform performs visual analysis on the IoT data of each target terminal, obtains visual data, and outputs the visual data.

[0113] In step 217, the network management platform sends a terminal takeover request to the portable station based on the acquired terminal identifier of the terminal to be taken over that is outside the designated area. The terminal takeover request includes the terminal identifier.

[0114] In step 218, the portable station sends a terminal takeover request to the operation service platform via the satellite Internet.

[0115] In step 219, the operation service platform sends the IoT data of the terminal to be taken over corresponding to the terminal identifier to the portable station.

[0116] In step 220, the portable station sends the IoT data of the terminal to be taken over to the data service platform.

[0117] In step 221, the data service platform performs visual analysis on the IoT data of each target terminal and the IoT data of the terminal to be taken over.

[0118] In step 222, when determining that all terminals that have accessed the private network are in an inactive state, the network management platform sends a request for reclaiming private network resources in a designated area to the portable station.

[0119] In a specific implementation, before the network management platform sends a request to reclaim the private network resources in the designated area to the portable station, it further includes determining that there are no terminals to be taken over outside the designated area that has been taken over.

[0120] In step 223, the portable station sends a private network resource recovery request to the operation service platform.

[0121] In step 224, the operation service platform reclaims the private network resources in the designated area.

[0122] Figure 3 A flowchart of a satellite communication method is provided for an embodiment of the present application, the method is applied to Figure 1 a network management platform in , and the method comprises the following steps.

[0123] In step 301, the private network demand of a specified area is obtained.

[0124] In step 302, the private network demand is sent to a portable station.

[0125] In step 303, the private network resource sent by the portable station is received.

[0126] In specific implementation, the portable station sends the private network demand to the operation service platform through the satellite Internet to trigger the operation service platform to construct the private network, receives the private network resource sent by the operation service platform, and sends the private network resource to the network management platform.

[0127] In step 304, the access demand of each target terminal in the specified area is obtained.

[0128] In step 305, based on the access demand, it is judged whether the current available private network resource meets the access demand of the target terminal, if yes, step 306 is entered, if not, step 307 is entered.

[0129] In step 306, the private network resource is allocated to the target terminal from the current available private network resource, wherein the allocated private network resource is used to access the target terminal to the private network.

[0130] In step 307, it is judged whether there is a terminal meeting the resource recycling condition among the terminals accessing the private network, if yes, step 308 is entered, if not, step 309 is entered.

[0131] In step 308, at least part of the private network resource of the terminal meeting the resource recycling condition is recycled, and the private network resource is allocated to the target terminal based on the available private network resource and the recycled private network resource.

[0132] In step 309, the private network resource is re-applied to the operation service platform for allocation.

[0133] In step 310, when it is determined that all the terminals accessing the private network are in an inactive state, the private network resource recycling request for the specified area is sent to the portable station to trigger the operation service platform to recycle the private network resource of the specified area.

[0134] Next, the scheme of the embodiment of the present application is introduced taking an emergency rescue scene as an example, in the emergency rescue scene, the satellite communication system can be called agile application system.

[0138] Agile application systems mainly involve platform layer, resource management layer, transmission layer and terminal layer, which can correspond to five subsystems according to their functions, including: data service subsystem, operation management subsystem, communication subsystem, terminal and technical support subsystem.

[0139] The four subsystems—the data services subsystem, the operations management subsystem, the communications subsystem, and the technical support subsystem—serve as the core of the agile application system. These subsystems utilize a miniaturized and componentized design, offering portable, vehicle-mounted, and ship-mounted configurations for rapid and flexible deployment, adapting to diverse emergency scenarios. The terminal, serving as the "perception layer" of the agile application system, acquires data from various user endpoints and transmits it back to the core agile application system, forming a local data closed loop. This enables rapid aggregation and processing of IoT data, ensuring its security.

[0140] (1) Application service subsystem

[0141] The application service subsystem, as the data core of the system, mainly includes: small data center, data service platform, operation service platform, etc., and is responsible for the processing, parsing, analysis and application of IoT data.

[0142] (2) Operation management subsystem

[0143] The operation and management subsystem serves as the management core of the system, and mainly includes: network management platform, small core network, small access network, etc. It is responsible for the application and release of private network resources, private network resource allocation and scheduling, terminal management, system status monitoring and other functions.

[0144] 1) Application and release of private network resources: Apply for private network resources from the operation service platform, release private network resources, and synchronize network resource status information.

[0145] 2) Private network resource allocation and scheduling: Private network resources can be simulated and planned based on the terminal access requirements, private network resources can be coordinated, and private network resource allocation plans (priority, bandwidth, etc.) for each terminal can be generated, and flexible scheduling can be performed manually or automatically.

[0146] 3) Terminal management: manage all terminals in the private network, including terminal registration, network access, authentication, network exit, etc.

[0147] 4) System state monitoring: can monitor the state of agile application system equipment, network state, security state, etc.

[0148] (3) Communication subsystem

[0149] The communication subsystem accesses the satellite Internet through a user channel or a power supply channel, mainly including antennas, channels, baseband devices, etc. According to different access methods, it can be accessed through the following two ways:

[0150] Method one: user channel: Ka user beam carries power supply service. The portable station accesses the satellite Internet as a terminal at ordinary times, and applies to the operation service platform when it needs private network service, and then converts the portable station through the protocol to receive and send power supply data through the Ka user beam.

[0151] Method two: power supply channel: Q / V power supply beam carries power supply service. Using the idea of portable station + mobile / broadband terminal, access the satellite Internet through mobile / broadband terminal at ordinary times, and apply to the operation service platform when it needs private network service, and then receive and send power supply data through the portable station.

[0152] (4) Satellite Internet terminal

[0153] The satellite Internet terminal includes both conventional terminals: mobile communication terminals, Internet of Things terminals, broadband terminals, etc., and fusion terminals and gateways: Tongdu fusion terminal, low-orbit fusion terminal, satellite-ground fusion gateway, etc.

[0154] (5) Technical support subsystem

[0155] The technical support subsystem mainly includes timing devices, network security devices, test calibration, switches, toolboxes, etc., providing Beidou / GPS time and frequency unification, basic network security, test and maintenance support for the system.

[0156] Figure 6 A system flowchart of the agile application system provided by the embodiments of the present application.

[0157] The agile application system mainly applies for private network resources to the operation service platform, configures the private network by the core network, completes the decentralization of private network resources and management authority, manages the terminals and private network by the network management platform, and forms a self-contained private network. The system flow mainly includes 5 steps, including: private network application, terminal registration, data closed loop, private network management and private network release.

[0158] Step one: private network application

[0159] 1) Application before: access to satellite Internet through the configured portable station, keep the application link unblocked, apply for private network service at any time through online or offline way.

[0160] 2) Application in progress: the network management platform applies for private network to the operation service platform (including area, time, bandwidth, etc.), the operation service platform plans after calling the core network interface to complete private network configuration, the core network completes network slice division, and finally the operation service comprehensive platform feeds back the application result and network permission to the network management platform.

[0161] 3) Application after: get private network resources.

[0162] Step two: terminal registration

[0163] 1) New terminal in specified area: the network management platform completes terminal registration and information input, configures priority, bandwidth, etc. for each terminal, and after the terminal registration is completed by the small core network, the state of each terminal is activated.

[0164] 2) Terminal outside the specified area: for the to-be-taken-over terminal that needs to be temporarily taken over, the to-be-taken-over terminal registration information can be synchronized to the agile application system small core network through the operation service comprehensive platform, and the to-be-taken-over terminal is temporarily managed and data is obtained.

[0165] Step three: data processing

[0166] Each registered terminal accesses the private network at the small core network, through the private network channel, the data falls to the agile application system small core network, and then the data service platform completes data processing and pushes it to the command center to form a data closed loop.

[0167] Step four: private network management

[0168] In the actual use of private network, the network management platform completes the dynamic management and allocation of resource parameters such as terminal access, withdrawal, priority, permission, bandwidth, etc. in private network, and the small core network executes.

[0169] Step five: private network release

[0170] 1) Terminal release: change the terminal that has accessed the private network to the non-activated state by the network management platform, or release the management permission of the temporary terminal;

[0171] 2) Network release: when it is determined that the terminals that have accessed the private network are all in the non-activated state, apply to the operation service platform to cancel the private network service, and recover the private network resources and management permission.

[0172] In this way, by constructing agile application systems through the advantages of high bandwidth and low latency private network communication capabilities of satellite Internet, the timeliness of data transmission can be effectively guaranteed, and the agile application system also has the following advantages:

[0173] Advantage one: agile deployment. Lightweight design can be flexibly and quickly installed and deployed on field, vehicle-mounted and ship-mounted platforms.

[0174] Advantage two: agile networking. Private network services can be applied at any time and anywhere, and full network resources can be allocated to specified areas for high-capacity, large-bandwidth, three-dimensional and multiple coverage protection.

[0175] Advantage three: agile access. With the global coverage advantage of satellite Internet, any region in the world can seamlessly access satellite Internet to take over the surrounding network and enjoy private network services at any time and in any weather.

[0176] Advantage four: agile service. Local data can be quickly processed and applied, and gateway station resources can be quickly accessed to obtain shared data, computing power and storage resources in real time.

[0177] Advantage five: agile management. Through flexible adaptation and dynamic management, the scheduling and collaborative response of private network resources in the private network can be quickly realized.
