Description

Technical Field

[0001] This application relates to the field of data processing technology, and in particular to an emergency communication system and method. Background Technology

[0002] In the event of major accidents and natural disasters, public communication networks may experience complete failure, causing severe impacts on social production and residents' lives. Emergency communications need to provide basic communication services to disaster victims to meet their basic needs such as emergency assistance and reporting their safety.

[0003] With the rapid development of technology, more and more new applications are being integrated into emergency rescue command, such as video intercom, high-definition temporary deployment, unmanned aerial vehicle patrols, and rescue robots. However, in existing emergency communication solutions, the systems providing communication services to emergency rescue personnel and on-site command centers are relatively independent from the systems providing communication services to disaster victims. This hinders more efficient collaborative emergency rescue operations and, constrained by the bandwidth limitations of satellite links, prevents the provision of a comprehensive range of services to disaster victims, thus limiting the ways in which communication with them can occur in emergency situations.

[0004] Therefore, existing emergency communication solutions have limitations and cannot provide diverse services to emergency rescue personnel, disaster victims, etc. at the same time, thus affecting rescue efficiency. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0043] In existing emergency communication solutions, the systems providing communication services to emergency rescue personnel and on-site command centers are relatively independent from the systems providing communication services to disaster victims. This makes it impossible to carry out more efficient emergency rescue collaborative operations. Furthermore, due to the bandwidth limitations of satellite links, it is impossible to provide a comprehensive range of different types of services to disaster victims, which in turn limits the ways to communicate with disaster victims in emergency situations.

[0044] Therefore, existing emergency communication solutions have limitations and cannot provide diverse services to emergency rescue personnel, disaster victims, etc. at the same time, thus affecting rescue efficiency.

[0045] To address the aforementioned issues, the technical concept of this application is as follows: through a unified emergency communication system, on the one hand, basic voice and data services can be provided to disaster victims; on the other hand, by combining the local offloading capabilities of edge cloud, localized high-bandwidth data services and low-latency control services can be provided to rescue personnel and disaster victims. The unified emergency communication system can also enable direct communication between disaster victims and rescue personnel, thereby improving the efficiency of emergency rescue.

[0046] refer to Figure 1 , Figure 1This is a schematic diagram of the structure of an emergency communication system provided in an embodiment of this application. The system includes airborne equipment, a satellite communication system, and public network core network equipment; wherein, the airborne equipment may include portable 5G base stations, User Plane Function (UPF) equipment, edge cloud equipment, and satellite communication equipment, and the satellite communication system may include orbital satellites and satellite ground stations.

[0047] Specifically, the user plane function UPF device communicates with the edge cloud device; the user plane function UPF device communicates with the portable 5G base station; the portable 5G base station communicates with the satellite communication device; the satellite communication device communicates with the orbiting satellite via a satellite link; the orbiting satellite communicates with the satellite ground station; and the satellite ground station communicates with the public network core network device via a pre-set leased link. This pre-set leased link can be an operator leased link.

[0048] Among them, portable 5G base stations, UPF equipment, Multi-Access Edge Cloud (MEC) equipment, and satellite transceiver equipment (i.e., satellite communication equipment) are carried by unmanned airships or rotary-wing drones. The unmanned airships or rotary-wing drones can provide hovering capability, have a long endurance, and can carry a load of more than 100 kg. They can carry communication equipment to the disaster area (i.e., emergency area) to provide stable service at the first time when a disaster occurs.

[0049] Airborne satellite communication equipment connects to orbiting satellites, while public network core network equipment connects to satellite ground stations via dedicated operator links. This establishes a transmission route between the airborne satellite communication equipment and the public network core network equipment, enabling portable 5G base stations and edge cloud devices to interoperate with the public network core network equipment, forming a unified user-managed emergency communication system.

[0050] Airborne portable 5G base stations, connected to the public network core network equipment via satellite links, serve as temporary access points for the operator's public network, providing unified wireless emergency communication services to disaster victims and rescue personnel in disaster-stricken areas. This enables information exchange between rescue personnel and users (such as disaster victims and the general public), allowing communication between rescue personnel terminals and user terminals via the 5G network. Simultaneously, by mounting the core network UPF and MEC edge cloud onto unmanned aerial vehicles (UAVs, such as unmanned airships or rotary-wing drones), high-bandwidth traffic can be locally offloaded and processed, enabling high-bandwidth emergency services for rescue personnel, such as video intercoms, mobile surveillance cameras, and patrol drones. Video services can also be provided to disaster victims; video service software can be deployed to MEC edge cloud devices, simplifying authentication mechanisms and allowing trapped disaster victims to proactively report their situation via video, or enabling rescue personnel to better understand the surrounding environment of trapped disaster victims through video calls, allowing for more precise rescue operations. Once emergency power and communication are restored in the emergency area, the communication equipment mounted on the unmanned aerial vehicle can be turned off or its coverage area changed to achieve seamless switching of communication services in the emergency area.

[0051] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0052] See Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of an emergency communication system provided in another embodiment of this application.

[0053] See Figure 2 The emergency communication system includes: airborne equipment, satellite communication system, and public network core network equipment.

[0054] The airborne equipment is connected to the satellite communication system via a satellite link, and the satellite communication system is connected to the public network core network equipment via a pre-set dedicated line link.

[0055] The airborne equipment is used to provide a first emergency communication requirement for the emergency area and to perform localized processing operations based on the first emergency communication requirement, wherein the first emergency communication requirement represents emergency communication services within the rescue personnel and / or emergency communication services between the rescue personnel and the disaster victims; the satellite communication system is used to provide transmission routes between the airborne equipment and the public network core network equipment; the public network core network equipment is used to provide a second emergency communication requirement for the emergency area and to perform emergency processing control operations based on the second emergency communication requirement, wherein the second emergency communication requirement represents emergency communication services reported by the disaster victims.

[0056] In this embodiment, the airborne equipment can be an airborne emergency communication system. The airborne equipment, carried by an unmanned aerial vehicle, provides emergency communication services for rescue personnel or between rescue personnel and disaster victims. This meets the diverse needs of current emergency rescue efforts and solves the problem of incoordination caused by rescue personnel and disaster victims using different communication systems.

[0057] Furthermore, airborne equipment can localize certain emergency communication services, such as high-bandwidth data services and low-latency control services. This allows for the localization of high-bandwidth data services and low-latency control services for rescue personnel and disaster victims, significantly saving transmission bandwidth on satellite backhaul links and thus reducing emergency communication costs. Simultaneously, localization reduces emergency communication latency, enabling low-latency emergency applications such as drone patrols and rescue robots.

[0058] The emergency communication system provided in this embodiment utilizes airborne equipment to provide a first emergency communication requirement to the emergency area and performs localized processing operations based on the first emergency communication requirement. The first emergency communication requirement represents emergency communication services within the rescue personnel and / or emergency communication services between rescue personnel and disaster victims. A satellite communication system provides transmission routing between the airborne equipment and the public network core network equipment. The public network core network equipment provides a second emergency communication requirement to the emergency area and performs emergency processing control operations based on the second emergency communication requirement. The second emergency communication requirement represents emergency communication services reported by disaster victims. Through the airborne equipment, satellite communication system, and public network core network equipment, on the one hand, it can provide reported emergency communication services, such as basic voice and data services, to disaster victims; on the other hand, combined with the local offloading capabilities of the airborne equipment, it can provide localized services to on-site emergency support personnel (i.e., rescue personnel) and disaster victims. It can also enable direct communication between disaster victims and emergency rescue personnel. Therefore, it can provide diverse services to emergency rescue personnel and disaster victims, thereby improving emergency rescue efficiency.

[0059] In one possible design, the airborne equipment includes a portable 5G base station, a data processing device, and a satellite communication device; the portable 5G base station is communicatively connected to the satellite communication device, and the satellite communication device is communicatively connected to the satellite communication system via the satellite link.

[0060] The portable 5G base station is used to provide wireless communication signals; the data processing equipment is used for localized processing of high-bandwidth data services and low-latency control services for rescue personnel and disaster victims; and the satellite communication equipment is used to provide transmission routes between the portable 5G base station and the public network core network equipment.

[0061] For example, a portable 5G base station acquires data. For data that needs to be processed locally, the portable 5G base station transmits the data to the edge cloud device for processing through the user plane function (UPF) device. For emergency call services, the data is transmitted to the core network device through the satellite communication device and then through the satellite communication system for processing.

[0062] In one possible design, the data processing device includes a User Plane Function (UPF) device and an edge cloud device, which are communicatively connected. The UPF device is also communicatively connected to the portable 5G base station and the satellite communication device.

[0063] The User Plane Function (UPF) device is used to provide routing and forwarding functions for user plane data packets; the edge cloud device is used to perform localized processing on the user plane data transmitted by the UPF device; the user plane data includes high-bandwidth data services and low-latency control services for rescue personnel and disaster victims.

[0064] In one possible design, the satellite communication system includes an orbiting satellite and a satellite ground station; the orbiting satellite and the satellite ground station are communicatively connected, the orbiting satellite is connected to the satellite communication equipment via a satellite link, and the satellite ground station is connected to the public network core network equipment via a pre-set dedicated line link.

[0065] In this embodiment, combined with Figure 1 As shown, the portable 5G base station is connected to the satellite communication equipment. The satellite communication equipment is connected to the orbiting satellite in the satellite communication system through a satellite link. The satellite ground station in the satellite communication system is connected to the public network core network equipment through a preset dedicated line link, thus realizing the interconnection between the portable 5G base station and the public network core network equipment.

[0066] The portable 5G base station communicates with edge cloud devices via User Plane Function (UPF) equipment, enabling edge cloud devices to process localized data, such as high-bandwidth data services and low-latency control services (e.g., cluster communication between rescue personnel, between rescue personnel and the on-site command center, and video-related big data services), without needing to transmit data back to the public core network via satellite links. This significantly saves satellite backhaul bandwidth resources and communication costs. Simultaneously, the localized service processing effectively improves the communication quality of on-site emergency rescue operations.

[0067] In one possible design, the airborne equipment is mounted on a drone, which has hovering capabilities.

[0068] In this embodiment, in order to reach the emergency area quickly and conveniently, an unmanned aerial vehicle (UAV) can be selected to carry onboard equipment, and in order to ensure the stability of the communication signal, the UAV has hovering capability.

[0069] In one possible design, the portable 5G base station is specifically used to provide wireless signals to both the emergency command terminal and the disaster victim terminal.

[0070] In this embodiment, communication can be established between the emergency command terminal and the disaster victim's terminal via a portable 5G base station. A detailed explanation follows using specific business scenarios.

[0071] Scenario 1: Emergency communication services for rescue personnel.

[0072] Combination Figure 3 As shown, the emergency command terminal includes a video intercom, a field command console, and a mobile surveillance sphere. The video intercom service stream generated by the video intercom is processed locally through the MEC edge cloud-based UPF. The mobile surveillance sphere continuously moves to monitor the service stream and then transmits the monitored service stream back to the field command console, which then directs rescue operations in the scene.

[0073] Specifically, rescue personnel will use specific terminal users and specific access point information (Special Data Network Name, DNN) to access portable 5G base stations. Cluster communication services between rescue personnel, and between rescue personnel and the on-site command center, as well as video-related big data services, can be offloaded and processed locally via public network-based UPF and edge cloud devices mounted on unmanned aerial vehicles. A large amount of data does not need to be transmitted back to the public network core network equipment via satellite links, significantly saving satellite backhaul bandwidth resources and communication costs. Simultaneously, the localized service processing effectively improves the communication quality of on-site emergency rescue. Notably, signaling interaction prior to localized processing requires transmission to the public network core network equipment.

[0074] Scenario 2: Emergency communication services between rescue workers and disaster victims.

[0075] Combination Figure 4 As shown, the emergency command terminal includes a video intercom, a field command console, and a mobile surveillance sphere. The request calls generated by the video intercom are transmitted to the public network core network equipment via a portable 5G base station, and then transmitted to the terminal of the disaster-stricken personnel. The mobile surveillance sphere continuously monitors the service flow and then transmits it back to the field command console, which then directs the rescue efforts.

[0076] Specifically, in situations where disaster victims are severely trapped, direct voice or video communication between rescuers and victims is necessary to increase the accuracy of rescue efforts. After receiving a distress call from a victim, rescuers can proactively dial their phone number. The call request passes through portable 5G base stations, airborne satellite communication equipment and satellite links, and public network core network equipment (i.e., the operator's core network) to ultimately establish a connection with the victim. Furthermore, video call software servers can be deployed on MEC edge cloud devices, allowing rescuers to guide victims in using the software to complete video calls. Video call services do not require satellite links, significantly saving satellite link resources, and the localized processing within the MEC also enhances the quality of video calls.

[0077] Scenario 3: Basic emergency communication services for disaster victims.

[0078] Combination Figure 5 As shown, the request call generated by the disaster victim's terminal is transmitted to the public network core network equipment via a portable 5G base station, and then the request call is transmitted to the emergency hotline.

[0079] Specifically, for disaster victims in emergency areas, such as ordinary disaster-stricken users, they can use common mobile phones and common access point information to connect to portable 5G base stations. When users make hotline calls or send text messages, the data is transmitted via onboard satellite communication equipment to an orbiting satellite, and then through a dedicated operator link from the satellite ground station to the public network core network equipment, thus completing the communication process. This allows disaster victims to proactively report disaster information and their location to emergency hotlines and obtain rescue assistance.

[0080] Furthermore, by improving the Quality of Service (QoS) level of emergency response personnel, the critical business priorities of these personnel can be effectively guaranteed. Simultaneously, core network equipment can control the external network data access bandwidth and data service access targets for disaster victims, ensuring that critical rescue calls can be made and limiting the waste of communication resources caused by disaster victims accessing unnecessary websites.

[0081] This application utilizes a portable 5G base station, a sunken UPF and edge cloud equipment, and satellite communication equipment mounted on an unmanned aerial vehicle. The portable 5G base station establishes a communication connection with an orbiting satellite through the onboard satellite communication equipment, and the public network core network equipment establishes a stable fiber optic connection with the satellite ground station through a dedicated line from an operator, thereby achieving routing interoperability between the portable 5G base station and the public network core network equipment.

[0082] Therefore, a unified emergency communication system can simultaneously address the needs of disaster victims for proactive information reporting and the diverse emergency communication needs of rescue personnel. It also enables direct voice or video communication between rescue personnel and disaster victims, significantly improving the efficiency of emergency rescue. By using UPF and MEC edge cloud devices mounted on unmanned aerial vehicles (UAVs), high-bandwidth data services and low-latency control services for emergency rescue personnel and disaster victims can be processed locally, greatly saving transmission bandwidth on satellite backhaul links and thus reducing emergency communication costs. Simultaneously, localized processing reduces emergency communication latency, enabling low-latency emergency applications such as UAV patrols and rescue robots.

[0083] This embodiment provides an emergency communication method, applied to the emergency communication system described in the above embodiments. See also... Figure 6 As shown, Figure 6 This is a flowchart illustrating an emergency communication method provided in an embodiment of this application. The method includes:

[0084] S101. If the communication service in the emergency area is an emergency communication service within the rescue personnel or an emergency communication service between the rescue personnel and the disaster victims, after the signaling interaction is completed, the communication service is processed by data diversion and localization through the airborne equipment in the emergency communication system.

[0085] S102. If the communication service in the emergency area is an emergency communication service reported by disaster victims, the data of the communication service will be connected to the public network core network equipment in the emergency communication system through the satellite communication system in the emergency communication system, and the data of the communication service will be processed through the public network core network equipment.

[0086] The application communication method provided in this embodiment, through airborne equipment, satellite communication systems, and public network core network equipment, can provide emergency communication services for disaster victims, such as basic voice and data services. On the other hand, combined with the local offloading capabilities of airborne equipment, it can provide localized services for on-site emergency support personnel (i.e., rescue personnel) and disaster victims. It can also enable direct communication between disaster victims and emergency rescue personnel. Therefore, it can provide diverse services for emergency rescue personnel and disaster victims, thereby improving the efficiency of emergency rescue.
