Description

Technical Field

[0001] The present invention relates to the field of satellite communication technology, and particularly to a method and system for networking and integrating a full-network-connection public network communication network based on satellite communication, which is applicable to scenarios such as emergency communication guarantee and communication coverage in remote areas that require the use of satellite communication to achieve multi-operator network integration. Background Art

[0002] In today's society, the development of communication technology is changing with each passing day, and people's demands for the stability, coverage range, and multi-network integration of communication networks are also increasing. As an important part of modern communication, satellite communication plays an irreplaceable role in scenarios such as emergency communication guarantee and communication coverage in remote areas.

[0003] Currently, a pico base station often accesses the Internet through a satellite network and then establishes a connection with the base station gateway system of a basic telecommunications operator to achieve 4G / 5G signal coverage. However, there are many defects in this existing communication network networking and integration method. First, the base station gateway system is deployed on the core network side of a single operator, which results in the pico base station only supporting the 4G / 5G signal coverage of a single operator and being unable to meet the user's demand for multi-operator network selection, with significant limitations in signal switching and network stability. For example, in some emergency rescue scenarios, the network of a single operator may not be able to meet the communication needs of a large number of rescue devices and personnel. If it is not possible to quickly switch to the network of other operators, it will seriously affect the progress of the rescue work.

[0004] Second, the communication between the pico base station and the base station gateway passes through the Internet, and the Internet environment is complex with high security risks, making it difficult to ensure network security during the communication process. Data is easily threatened by hacker attacks, data leakage, etc. during the transmission process on the Internet, which is a great security hazard for communication scenarios involving important information, such as military communication and financial communication.

[0005] In addition, with the continuous growth of communication demands, the existing technology has low management efficiency and high core network pressure when dealing with a large number of concurrent base station devices. At the same time, there is a lack of an effective terminal device and number access management mechanism, making it difficult to accurately control network resources and unable to well meet the diverse communication management needs in different scenarios. These problems seriously restrict the wide application and efficient development of satellite communication in multiple fields and urgently require a new technical solution to solve them. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to overcome the deficiencies of the prior art and provide a network integration method and system for a full-network public network communication network based on satellite communication. The present invention aims to solve the deficiencies of existing satellite communication network networking and integration technologies and focuses on achieving two key objectives. First, by deploying the "triple-play gateway system" in the communication management department and connecting to the networks of the three basic telecommunications operators, a single pico base station device can communicate with the core networks of each operator in the form of a private network through the high-throughput satellite communication network, realizing the coverage of 4G / 5G signals of the three operators by a single device, meeting the user's demand for multi-operator network selection, and improving the signal switching fluency and network stability. Second, a private communication link is constructed using the second-layer network of the high-throughput satellite communication network to avoid data transmission via the Internet, and an IPSec encryption link meeting the second-level standard of the national cryptography GM / T0028 is established between the pico base station and the security gateway to encrypt the signaling and service data between the base station and the core network, enhancing the network communication security and resisting various network security threats.

[0007] To achieve the above object, a first aspect of the present invention provides a network integration system for a full-network public network communication network based on satellite communication, including: A communication access module for realizing the communication access between the terminal and the network, including a pico base station device supporting triple-play and various forms of satellite communication terminals connected thereto; A data aggregation module responsible for aggregating the data of the pico base station device and transmitting it to the data aggregation gateway station, which is composed of multiple satellite gateway stations and realizes data aggregation through a private network; A triple-play gateway module is set in the communication management department for data processing, signaling conversion, service distribution, and base station device management, including a security gateway, a signaling gateway, and a base station network management; An operator core network module includes the core networks of multiple operators and is connected to the triple-play gateway module to process the base station service data; A unified management and scheduling module is deployed in the unified access platform for air-ground-space communication guarantee in the cloud, and is used to manage, monitor, and schedule the triple-play base stations and related satellite communication system resources, including a core network link monitoring subsystem and a fusion site management subsystem; among them, the core network link monitoring subsystem is used to monitor the core network link status and display relevant information; the fusion site management subsystem is used to comprehensively manage the full-network fusion sites.

[0008] Further, in the communication access module, the pico base station device has LTE / NR transceiver, radio resource management, and mobility management functions, and the satellite communication terminals are deployed at the emergency site, including drones, vehicle-mounted stations, and portable stations, and perform two-way communication with different satellite gateway stations through high-throughput satellites; In the data aggregation module, multiple satellite gateways build a Layer 2 private network through ground circuits, and the data aggregation gateway and the triple-play gateway module form a private network through point-to-point ground circuits; In the triple-play gateway module, the security gateway and the pico base station establish an encrypted link through IPSec. The signaling gateway is connected to the 4G / 5G core networks of three operators through point-to-point ground circuits, identifies the PLMN parameters of the base station signaling, aggregates the base station service data and automatically sends it to the corresponding operator's core network. The base station network management uniformly manages all access base station devices through the pico base station interface, and the convergence gateway supports the master-slave mode, and the transmission link supports master-slave redundant deployment.

[0009] Furthermore, in the core network link monitoring subsystem: Regularly obtain link data through an external interface and store it in a data table; Judge the link status according to the data in the data table and present different statuses on the display interface; at the same time, record the link status change information in another data table, and the dynamic information on the display interface also comes from this data table; Different operation enterprise roles obtain link information related to themselves through this subsystem.

[0010] Furthermore, the external interface is the core network firewall interface, and the obtained data is correspondingly stored in the LINK_INFO data table; The specific data table is the link_info table, which contains various attribute information of the link, including one or more of ID, link type, interruption time, recovery time, and status; another data table is the link_info_notice table, which is used to record link failure and recovery information.

[0011] Furthermore, in the convergence site management subsystem: Display a list of all network convergence sites, support paging operations, and users can adjust the number of displayed items per page and jump to different pages. At the same time, it has filtering and query functions, and can filter site records according to various conditions; Real-time statistics of relevant quantity information of the sites, and real-time update as the list data changes. Support manually modifying the status of the site accessing / disconnecting from the core network; Record the detailed information of the site accessing / disconnecting, support paging, filtering, and searching operations. Can view the statistical details of the site and export reports, and can also display and operate the approval forms and whitelist information related to the site, as well as export the list page to a specified format file.

[0012] Furthermore, the data comes from the EQUIPMENT_INFO_Rel data table, and various information of all network convergence sites is obtained through inter-table related queries; The associated approval form data is obtained by querying according to conditions in the TRIPLE_NETWORK_ACCESS table and the NETWORK_EQUIPMENT_REL table. The associated whitelist data is obtained by querying the latest successfully pushed records in the PUSH_NOTICE table based on the site ID. The access / disconnection records are obtained from the EQUIPMENT_ACCESS_INFO table, and the data is obtained by calling an interface.

[0013] The statistical information is obtained through a multi-table associated query, involving the data of two tables, BASE_NOW_INFO and BASE_ALL_INFO.

[0014] Furthermore, in a network environment, the pico base station and the security gateway transmit signaling data and service data through an IPSec link. The signaling gateway establishes connections with the MME network elements of each operator's core network respectively to realize signaling interaction between the base station and the core network.

[0015] The second aspect of the present invention provides a method for network integration of a satellite communication-based all-network public network communication network. Based on the above system, the method at least includes the following steps: Realize the communication access between the terminal and the network through the communication access module; Use the data aggregation module to aggregate and transmit the data of the pico base station equipment to the triple-network convergence gateway module; The triple-network convergence gateway module processes, distributes, and manages the base station equipment; The operator core network module processes the base station service data from the triple-network convergence gateway module; Perform resource management, monitoring, and scheduling through the unified management and scheduling module, specifically including: Use the core network link monitoring subsystem to regularly obtain core network link data through an external interface and store it. Judge the link status based on the stored data and display it, record the link status change information, and provide corresponding link information for different operator enterprise roles.

[0016] Use the integrated site management subsystem to display a list of all-network integrated sites, perform paging, filtering, and querying, count the quantity information related to the sites and update it in real time, manually modify the core network access / disconnection status of the sites, record the access / disconnection details of the sites, view and export the site statistical details, display and operate the approval form and whitelist information associated with the sites, and export the list page.

[0017] Furthermore, during communication access, the pico base station equipment is connected to multiple satellite communication terminals and communicates with the satellite gateway station through a high-throughput satellite; During the data aggregation process, the satellite gateway stations perform data aggregation through a layer-2 private network, and the data aggregation gateway station transmits the data to the triple-network convergence gateway module through a point-to-point terrestrial circuit; When the three-network convergence gateway module processes data, an encrypted link is established between the pico base station and the security gateway through IPSec for data transmission. The signaling gateway identifies the PLMN parameters of the base station signaling and sends the service data to the corresponding operator core network. The base station network management uniformly manages the base station devices through the pico base station interface.

[0018] Further, in a network environment, the steps of transmitting signaling data and service data between the pico base station and the security gateway through an IPSec link, and the signaling gateway establishing connections with the MME network elements of each operator core network respectively to achieve signaling interaction are executed.

[0019] The entire communication link does not pass through the Internet and uses a private network connection, including the layer 2 network between the satellite communication terminal and the satellite gateway station, the layer 2 private network between gateway stations, the private network between the data aggregation gateway station and the three-network convergence gateway module, and the private network between the three-network convergence gateway module and the operator core network.

[0020] The present invention adopts the above technical solutions, and has the following specific beneficial effects: 1. With the help of the three-network convergence gateway system, a single pico base station device can simultaneously provide 4G / 5G signal coverage for three operators. In emergency rescue scenarios, rescue personnel can freely select the operator network with the best signal according to the on-site network signal strength to ensure stable and unobstructed communication. In remote areas, where there may be problems with insufficient coverage of a single operator network in the past, the present invention can integrate the resources of multiple operators to expand the network coverage and meet the communication needs of local residents and enterprises.

[0021] 2. Various satellite communication terminals in the system, such as drones, vehicle-mounted stations, portable stations, etc., can be flexibly deployed in various complex environments. In areas where ground communication facilities are severely damaged, such as mountainous areas and disaster areas, the satellite communication terminal carried by the drone can quickly take off and establish a temporary communication link to ensure the timely transmission of rescue command and on-site situation.

[0022] 3. The entire communication link does not pass through the Internet. From the layer 2 network transmission between the satellite communication terminal used by the pico base station and the satellite gateway station, to the data aggregation between gateway stations, and then to the connection between the three-network convergence gateway system and the operator core network, a private network form is adopted. This effectively avoids security risks brought by the Internet, such as hacker attacks and network monitoring, and ensures the security and confidentiality of communication data.

[0023] 4. An encrypted link is established between the pico base station and the security gateway of the three-network convergence gateway system through IPSec that meets the national cryptography GM / T0028 level 2 standard to encrypt all signaling data and service data between the base station and the core network. In fields highly sensitive to information security such as financial communication and military communication, it can prevent data leakage and tampering and ensure the integrity and reliability of information.

[0024] 5. In the convergence gateway service system of the triple-play network, the convergence gateway and network management are deployed in hardware and support the 1+1 primary and standby mode. The transmission link also supports primary and standby redundant deployment. When the primary device or primary link fails, the standby device or link can quickly switch to be put into use to ensure the uninterrupted operation of the system. At the scene of large-scale events, a large number of users use communication devices simultaneously. This redundant design can ensure the stable operation of the network and avoid communication interruptions.

[0025] 6. Through the unified access platform for air-space-ground communication guarantee deployed in the cloud, centralized management and monitoring and scheduling of triple-play network base stations and related satellite communication system resources can be realized. The users of the telecommunications administration and the personnel of the emergency support units can real-time master the network operation status, discover and solve problems in a timely manner, and improve the emergency communication guarantee ability and work efficiency. In the face of emergencies, resources can be quickly allocated to ensure that the communication network meets the emergency requirements.

[0026] 7. The triple-play network gateway system uses the multi-operator core network automatic identification technology to identify the PLMN parameters of the base station signaling and automatically transmit the service data to the corresponding operator core network. This process requires no manual intervention, improves the accuracy and efficiency of data transmission, reduces the management overhead. At the same time, it avoids the misrouting of service data and optimizes the utilization of core network resources.

[0027] 8. The base station network management uniformly manages all base station devices accessing the triple-play network gateway system through the pico base station interface, realizing alarm management, configuration management and performance management of the base station devices. It can real-time monitor the operation status of the base station devices, discover and handle faults in a timely manner, optimize the configuration of the base station devices, and improve the performance and service life of the devices.

The pico base station device has LTE / NR transceivers, radio resource management, and mobility management functions, and can simultaneously process communication signals of different operators to ensure seamless handover of users between different networks. The satellite communication terminals are deployed at the emergency site. Among them, the satellite communication terminal carried by the drone can quickly take off and establish a communication link in complex terrains and environments to provide timely communication support for on-site command and rescue; the vehicle-mounted station can move with the rescue vehicle to ensure that the rescue personnel always maintain smooth communication during the movement; the portable station is convenient for the rescue personnel to carry to remote or weak-signal areas to achieve flexible communication access. In addition, after the pico base station device is connected to the satellite communication terminal, it conducts two-way communication with the satellite gateway station via a high-throughput satellite.

[0032] Data aggregation module: It consists of multiple satellite gateway stations, and its responsibility is to aggregate the data of the pico base station device and transmit it to the data aggregation gateway station. As shown in the attached Figure 1 , a Layer 2 private network is constructed between multiple satellite gateway stations such as Satellite Gateway Station 1 and Satellite Gateway Station 2 through a ground circuit, and the data aggregation gateway station and the triple-play integration gateway module form a private network through a point-to-point ground circuit.

[0033] Triple-play Convergence Gateway Module: Installed in the communication management department's computer room, it includes a security gateway, a signaling gateway, and a base station network management system, and is used for data processing, signaling conversion, service distribution, and base station equipment management. Combined with Appendix Figure 1 and Appendix Figure 2 As can be seen, the pico base station equipment and the security gateway establish an encrypted link through IPSec to achieve encrypted transmission of signaling data and service data between the base station and the core network, thereby ensuring the confidentiality and integrity of data during transmission. The signaling gateway is connected to the 4G / 5G core networks of the three major operators through point-to-point terrestrial circuits, can identify the PLMN parameters of the base station signaling, converge the base station service data and automatically send it to the corresponding operator's core network, improving the accuracy and timeliness of service data transmission. The base station network management system uniformly manages all base station equipment accessing the triple-play convergence gateway module through the pico base station interface, and can achieve remote monitoring, fault diagnosis, and configuration update of the base station equipment to ensure the stable operation of the base station equipment. In addition, the convergence gateway in the triple-play convergence gateway module, including the security gateway and the signaling gateway, supports the main-backup mode. When the main device fails, the standby device can automatically switch to ensure the uninterrupted operation of the system; the transmission link supports main-backup redundant deployment to further ensure the reliability of data transmission. As can be seen from Appendix Figure 2 it can also be seen that in the entire network architecture, this module collaborates with network elements such as MME (Mobility Management Entity), SGW (Serving Gateway), and PGW (Packet Data Network Gateway) to jointly achieve signaling interaction and service data processing.

[0034] Operator Core Network Module: It includes the core networks of multiple operators. As can be seen from Appendix Figure 1 the core networks of China Telecom, China Mobile, and China Unicom are connected to the triple-play convergence gateway system through dedicated lines. This module is connected to the triple-play convergence gateway module and is responsible for processing base station service data, further processing and distributing the base station service data, and realizing interconnection and interoperability with other networks. For example, it transmits voice data to the voice switching network and data services to the Internet, etc.

[0036] Such as Figure 1As shown in the figure, the overall architecture of the all-net public network communication network networking integration system based on satellite communication is presented. Among them, the communication access module includes pico base station devices (Smallcell) that support triple-play integration and various satellite communication terminals, such as drones, vehicle-mounted stations, portable stations, etc. They are connected to the satellite gateway station through high-throughput satellites to achieve communication access between the terminals and the network, providing communication services of multiple operators for users. The data aggregation module consists of multiple satellite gateway stations, which build a layer-2 private network through ground circuits to aggregate the data of pico base station devices to the data aggregation gateway station and then transmit it to the triple-play integration gateway module to ensure the efficiency and security of data transmission. The triple-play integration gateway module is set in the communication management department and includes a security gateway, a signaling gateway, and a base station network management, responsible for the secure processing of data, signaling conversion, service distribution, and unified management of base station devices. The operator core network module is connected to the triple-play integration gateway module to process the base station service data and achieve interconnection and interoperability with other networks. The unified management and scheduling module is deployed in the cloud to manage, monitor, and schedule the triple-play integration base stations and related satellite communication system resources. The core network link monitoring subsystem under it is used to monitor the status of the core network link, and the integrated site management subsystem is used to comprehensively manage the whole-network integrated sites.

[0037] Core network link monitoring subsystem: This subsystem regularly obtains link data through the core network firewall interface and stores it in the LINK_INFO data table (corresponding to the specific link_info table, which contains attribute information such as the ID, link type, interruption time, recovery time, and status of the link). The link status is judged based on the data in this table. If the link fails, the corresponding line on the display diagram will be shown in red, and if it is unobstructed, it will be shown in green. When the link fails, fault information is added to the link_info_notice table. When the link returns to normal, the recovery time of the corresponding data in this table is modified. The information dynamic broadcast area on the right side of the page obtains data from the link_info_notice table to display link disconnection and connection information. After different operator enterprise roles log in to the system, the link-related information they see is different.

[0038] Fusion Site Management Subsystem: Displays all the network's fusion sites in a list. When there is too much data, it shows data in pages, with 10 data items displayed per page by default. Users can manually adjust the number of data items shown per page. It supports filtering by online / offline status, access / disconnection from the core network status, and fuzzy query through the search box. The number of sites, online number, offline number, access number, and disconnection number are statistically calculated in real time above the page. The access / disconnection from the core network status of each data item can be manually modified. Records of the detailed information of each data item's access / disconnection, including the number of times, time, operation type, operator, etc., support pagination, filtering, and searching.

[0039] The second aspect of the present invention provides a method for networking and fusing a full-network public network communication network based on satellite communication, and the specific steps are as follows: Communication access step: Realize the communication access between the terminal and the network through the communication access module. Mobile user terminals (UEs) first establish a connection with the pico base station device through the Uu interface, and then the pico base station device communicates with the security gateway through the IPSec link, and further communicates with the satellite gateway station through the satellite network. The pico base station device is connected to various forms of satellite communication terminals and communicates with the satellite gateway station through high-throughput satellites. During the connection process, the pico base station device communicates with the satellite communication terminal through communication protocols to ensure stable signal transmission. The satellite communication terminal automatically selects the best satellite gateway station for connection according to its own positioning information and the surrounding environment to improve communication efficiency.

[0040] Data aggregation step: Use the data aggregation module to aggregate and transmit the data of the pico base station equipment to the triple-play gateway module. Data is aggregated between satellite gateways through a layer-2 private network, and the data aggregation gateway station transmits the data to the triple-play gateway module via a point-to-point terrestrial circuit. During the data aggregation process, the satellite gateway station collects and organizes the data of the pico base station equipment to ensure the integrity and accuracy of the data. During the data transmission process, the private network is used to ensure the reliable transmission of the data.

[0041] Data processing and management step: The triple-play gateway module processes, distributes, and manages the base station equipment. The security gateway first encrypts the data from the pico base station and then transmits it to the signaling gateway. The signaling gateway sends the service data to the corresponding operator core network via a dedicated line according to the PLMN parameters, such as sending it to the MME, and then completing the service processing process through the SGW, PGW, etc. An encrypted link is established between the pico base station and the security gateway through IPSec to transmit data; the signaling gateway identifies the PLMN parameters of the base station signaling and sends the service data to the corresponding operator core network; the base station network management uniformly manages the base station equipment through the pico base station interface. When establishing an encrypted link between the pico base station and the security gateway, key negotiation is carried out to ensure the security of the encrypted link. After the signaling gateway identifies the PLMN parameters, it sends the service data to the corresponding operator core network according to the preset routing policy to improve the accuracy of data transmission. The base station network management collects the operation data of the base station equipment regularly, conducts performance evaluation and fault prediction on the base station equipment, and performs maintenance and optimization in advance.

[0042] Service processing step: The operator core network module processes the base station service data from the triple-play gateway module. After receiving the base station service data, the operator core network classifies and processes it according to the service type. For example, for voice services, it is transmitted to the voice switching network for switching and processing; for data services, it is forwarded to the Internet for transmission and processing.

[0043] Management and scheduling step: Resource management, monitoring, and scheduling are carried out through the unified management and scheduling module, specifically including: Such as Figure 2As shown, the specific steps of the network integration method for the all-net public network communication network based on satellite communication are presented. First, through the communication access module, the pico base station device is connected to various satellite communication terminals, communicates with the satellite gateway station via the high-throughput satellite, and realizes the communication access between the terminal and the network. Next, using the data aggregation module, the satellite gateway stations perform data aggregation through the layer-2 private network, and the data aggregation gateway station transmits the data to the triple-play gateway module via the point-to-point terrestrial circuit. Then, the triple-play gateway module processes, distributes, and manages the base station device. An encrypted link is established between the pico base station and the security gateway through IPSec to transmit data. The signaling gateway identifies the PLMN parameters of the base station signaling and sends the service data to the corresponding operator core network. The base station network management uniformly manages the base station device through the pico base station interface. After that, the operator core network module processes the base station service data from the triple-play gateway module. Finally, through the unified management and scheduling module, resource management, monitoring, and scheduling are carried out. The core network link monitoring subsystem is used to monitor the core network link status, and the integrated site management subsystem is used to perform operations such as listing display, screening, and statistics on the whole-network integrated sites, so as to realize the efficient operation and management of the entire communication network.

[0044] Using the core network link monitoring subsystem, the core network link data is obtained regularly through the core network firewall interface and stored in the LINK_INFO data table. The link status is judged based on the stored data and different statuses are presented on the display interface. The link status change information is recorded in the link_info_notice table to provide corresponding link information for different operator enterprise roles.

[0045] Using the integrated site management subsystem, the whole-network integrated sites are listed, paged, screened, and queried. The relevant quantity information of the sites is statistically calculated and updated in real time. The access / disconnection status of the sites to / from the core network is manually modified, the details of the site access / disconnection are recorded, the statistical details of the sites are viewed and exported, the approval forms and whitelist information associated with the sites are displayed and operated, and the list page is exported.

[0046] In the network environment, the steps of transmitting signaling data and service data between the pico base station and the security gateway through the IPSec link, and the signaling gateway establishing connections with the MME network elements of each operator core network respectively to realize signaling interaction are executed. The entire communication link does not pass through the Internet and uses a private network connection, including the layer-2 network between the satellite communication terminal and the satellite gateway station, the layer-2 private network between the gateway stations, the private network between the data aggregation gateway station and the triple-play gateway module, and the private network between the triple-play gateway module and the operator core network.

[0047] Embodiment of the emergency rescue scenario After an earthquake disaster occurred in a certain remote mountainous area, the local communication infrastructure was severely damaged and the ground network was paralyzed. The network integration system of the present invention responded quickly, and the implementation steps are as follows: Emergency rescue teams carry satellite communication terminals such as portable stations and vehicle-mounted stations to the disaster area. Select a suitable location in the disaster area, install the portable station in the rescue command center, and deploy the vehicle-mounted station on mobile rescue vehicles. At the same time, install 4G triple-network convergence base station equipment on the front-end communication facilities at the scene to ensure effective connection with satellite communication terminals.

[0048] The satellite communication terminals of the portable station and the vehicle-mounted station establish communication links with different satellite gateway stations through high-throughput satellites. The satellite gateway stations form a two-layer private network using ground circuits, and converge the pico base station data to the data convergence gateway station. The data convergence gateway station is then connected to the triple-network convergence gateway system deployed in the communication management department through a point-to-point ground circuit.

[0049] The triple-network convergence base station equipment provides 4G / 5G signal coverage for the mobile terminals of on-site rescue personnel. Devices such as the mobile phones and walkie-talkies of rescue personnel can access this network to realize functions such as voice calls and data transmission. An encrypted link is established between the pico base station and the security gateway through IPSec that meets the national cryptography GM / T0028 second-level standard to ensure the security of communication data. The signaling gateway identifies the PLMN parameters of the base station signaling and automatically transmits the service data to the corresponding operator core network to ensure that rescue personnel can communicate smoothly with the outside world.

[0050] Users of the telecommunications administration and personnel of emergency support units can, through the "Unified Access Platform for Air-Space-Ground Communication Guarantee" deployed in the cloud, monitor the operation status of the triple-network convergence base stations at the disaster area site and the resource usage of the satellite communication system in real time. Use the core network link monitoring subsystem to monitor the core network link status, discover and handle link failures in a timely manner; manage the converged sites in the disaster area through the converged site management subsystem, flexibly allocate satellite channel resources according to rescue needs, and give priority to ensuring the communication needs of key rescue tasks. At the same time, remotely manage and maintain the base station equipment and handle possible failures in a timely manner.

[0051] Embodiment of Communication Coverage in Remote Areas In a certain remote island, local residents have long faced problems such as poor communication signals and insufficient network coverage. To improve the communication situation, the system of the present invention is used for construction: Install 4G triple-network convergence base station equipment at the center of the island and configure satellite communication terminals adapted thereto. Set up multiple satellite gateway stations in the higher areas around the island to ensure the signal coverage range and intensity.

[0052] The satellite communication terminal communicates with the satellite gateway station through the high-throughput satellite. The satellite gateway stations form a layer-2 private network through the ground circuit, and converge the pico base station data to the data aggregation gateway station. The data aggregation gateway station is connected to the triple-play gateway system of the communication management department through a point-to-point ground circuit. The signaling gateway in the triple-play gateway system is simultaneously connected to the core networks of the three major operators, namely China Telecom, China Mobile, and China Unicom, to enable a single pico base station device to provide 4G / 5G signal coverage for the three major operators.

[0053] The mobile phones, smart devices, etc. of local residents can access the network of the triple-play base station and enjoy stable communication services. Whether it is voice calls, video chats, or applications such as online shopping and online learning, they can all be satisfied. Since the communication link does not pass through the Internet and uses encrypted transmission, the security of the residents' communication data is guaranteed.

[0054] Through the "Unified Access Platform for Space-Air-Ground Communication Guarantee", the core network link monitoring subsystem is used to monitor the status of the core network link in real time, and the integrated site management subsystem is used to remotely manage and monitor the triple-play base stations on the island. The operating status, signal strength, user traffic and other indicators of the base station are monitored in real time, and the base station parameters are adjusted according to the actual situation to optimize the network performance. At the same time, the resources of the satellite communication system are reasonably scheduled to ensure the efficient use of network resources.

[0055] Embodiment of Communication Guarantee for Large Events When hosting an international sports event, a large number of spectators and staff pour into the host city, putting huge pressure on the communication network. The system of the present invention has played an important role: In the stadium and its surrounding areas, multiple pico base station devices supporting triple-play are temporarily deployed, and satellite communication terminals such as drones and vehicle-mounted stations are equipped. Ensure that stable communication signals can be provided in crowded areas.

[0056] The satellite communication terminal communicates with the satellite gateway station. The satellite gateway stations converge the pico base station data to the data aggregation gateway station through the layer-2 private network and then transmit it to the triple-play gateway system. The signaling gateway identifies the PLMN parameters of the base station signaling and automatically transmits a large amount of service data accurately and quickly to the corresponding operator's core network to meet the communication needs of spectators and staff during the event.

[0057] The encrypted link between the pico base station and the security gateway ensures the security of communication data and prevents information leakage. The integrated gateway and network management of the triple-play gateway system adopt a 1+1 primary and standby mode, and the transmission link also has a primary and standby redundant deployment to ensure the stable operation of the network under high load and avoid problems such as communication lags and interruptions.

[0058] Through the "Unified Access Platform for Air-Space-Ground Communication Guarantee", the core network link monitoring subsystem is used to grasp the operation status of the core network link in real time, and the integrated site management subsystem is used to centrally manage and monitor all temporarily deployed triple-play base stations. According to the communication requirements in different stages of the event, the resources of the satellite communication system are flexibly allocated to ensure the smooth progress of the event.

[0059] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
