Description

Technical Field

[0001] This disclosure relates to the field of communications, specifically to over-the-air base station communications, and more specifically to a network communication method, apparatus, electronic device, computer-readable storage medium, and computer program product for an over-the-air base station. Background Technology

[0002] An aerial base station is an aerial facility capable of providing communication services. With technological advancements, its applications are becoming increasingly widespread. Aerial base stations are used to extend communication coverage or provide stable communication services in specific areas. They can be temporary communication devices carried by drones. Aerial base stations provide communication services to ground users, particularly in natural disasters, remote areas, or special events, offering emergency communication support. Drone-borne aerial base stations represent an innovative communication solution that not only addresses communication restoration needs in emergencies such as natural disasters but also plays a crucial role in promoting global network access and enhancing technology and applications in the low-altitude economy. For example, in situations of power and network outages in disaster areas, drone-borne aerial base stations can rapidly deploy emergency communication services, providing essential communication support to rescue workers and residents.

[0003] Existing drone-borne airborne base stations (4G or 5G base stations) typically achieve network communication connections through both wired and wireless methods. Figure 1 The diagram illustrates the wireless communication connection of an over-the-air base station, such as... Figure 1 As shown, the airborne base station is located on the drone, which also has a satellite terminal. The base station establishes a connection with the ground core network through the satellite terminal. Its disadvantages are that the communication payload on the drone has high power consumption and heavy weight, and it can only rely on satellite for backhaul, making it difficult to complete communication conveniently and efficiently. Figure 2 This diagram schematically illustrates the wired communication connection of an over-the-air base station, such as... Figure 2 As shown, a tethered drone is used, with an RRU (Remote Radio Unit, a component of a mobile base station) or an airborne base station mounted on it. The airborne base station (or RRU) and ground equipment are connected via a hybrid fiber optic cable. The ground equipment then connects to the ground core network via a wired network (fiber optic or Ethernet cable) or a satellite module. The disadvantages are that the connection between the ground equipment and the drone restricts the drone's flight position and altitude, and the complex equipment makes deployment difficult. Summary of the Invention

[0042] The embodiments of the present disclosure will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the disclosure. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of the present disclosure for ease of explanation. However, it will be apparent that one or more embodiments may be practiced without these specific details. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts of the present disclosure.

[0043] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. The terms “comprising,” “including,” etc., as used herein indicate the presence of features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0044] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0045] When using expressions such as "at least one of A, B and C", they should generally be interpreted in accordance with the meaning that is commonly understood by those skilled in the art (e.g., "a system having at least one of A, B and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B and C, etc.).

[0046] It should be noted that the network communication method and apparatus for airborne base stations provided in this disclosure can be applied to the field of communication, the field of airborne base station communication technology, or any field outside the above-mentioned technical fields. The specific application field of the network communication method and apparatus for airborne base stations provided in this disclosure is not limited.

[0047] The embodiments of this disclosure provide a network communication method for an airborne base station.

[0048] Figure 3 The illustrations depict application scenarios of network communication methods, apparatuses, electronic devices, computer-readable storage media, and computer program products of airborne base stations according to embodiments of the present disclosure.

[0049] like Figure 3As shown, application scenario 300 according to this embodiment may include a base station and terminal communication scenario. Network 304 is used as a medium to provide a communication link between ordinary terminal devices 301, 302, 303 and base station 305. Network 304 may include various connection types, such as wired, wireless communication links, satellite links, or fiber optic cables, etc., and base station 305 may be an over-the-air base station.

[0050] Users can use ordinary terminal devices 301, 302, and 303 to interact with base station 305 via network 304 to receive or send messages, etc. Various communication client applications can be installed on ordinary terminal devices 301, 302, and 303, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, social media platform software, etc. (for example only).

[0051] Ordinary terminal devices 301, 302, and 303 can be various electronic devices with a display screen that support web browsing, including but not limited to smartphones, tablets, laptops, and desktop computers.

[0052] Base station 305 can provide communication services to ordinary terminal devices 301, 302, and 303 for ground users. Through the core network of base station 305, special terminal device 307, and gateway 309, it provides support for websites browsed by users using ordinary terminal devices 301, 302, and 303 (this is just an example). It analyzes and processes received user requests and other data, and feeds back the processing results (such as web pages, information, or data obtained or generated based on user requests) to the corresponding terminal devices.

[0053] like Figure 3 As shown, network 306 serves as a medium for providing a communication link between special terminal device 307 and base station 305. Network 306 utilizes the wireless communication link to connect special terminal device 307 and base station 305.

[0054] Special terminal equipment 307 is a terminal equipment with special preset service flow / signaling flow that is improved from ordinary terminal. It connects base station 305 and gateway 309 and is responsible for network communication between base station 305 and gateway 309.

[0055] like Figure 3 As shown, network 308 is a medium used to provide a communication link between special terminal device 307 and gateway 309. Network 308 may include various connection types, such as wired, wireless communication links, satellite links, or fiber optic cables, etc.

[0056] Gateway 309 acts as a computer system or device that performs the conversion task. Used between two systems with different communication protocols, data formats, or languages, or even completely different architectures, the gateway repackages the received information to suit the needs of the specific terminal device 307.

[0057] It should be noted that the network communication method of the airborne base station provided in this embodiment can generally be executed by the base station 305. Correspondingly, the network communication device of the airborne base station provided in this embodiment can generally be located in the base station 305. The network communication method of the airborne base station provided in this embodiment can also be executed by a server or server cluster that is different from the base station 305 and capable of communicating with ordinary terminal devices 301, 302, 303 and / or the base station 305. Correspondingly, the network communication device of the airborne base station provided in this embodiment can also be located in a server or server cluster that is different from the base station 305 and capable of communicating with ordinary terminal devices 301, 302, 303 and / or the base station 305.

[0058] It should be understood that Figure 3 The number of ordinary terminal devices, special terminal devices, networks, gateways, and base stations shown is merely illustrative. Depending on implementation needs, any number of ordinary terminal devices, special terminal devices, networks, gateways, and base stations can be included.

[0059] The following will be based on Figure 3 The described scene, through Figures 4-12 The network communication method of the airborne base station according to the disclosed embodiments will be described in detail.

[0060] Figure 4 A flowchart illustrating a network communication method for an airborne base station according to an embodiment of the present disclosure is shown schematically.

[0061] like Figure 4 As shown, the network communication method of the airborne base station in this embodiment includes operations S410 to S440.

[0062] In operation S410, based on a preset connection method, connections are established with m terminals to identify n special terminals; where the terminals include ordinary terminals and special terminals; and where m and n are integers not less than 1.

[0063] In operation S420, bidirectional authentication is performed on n special terminals to obtain p special terminals that pass authentication; where p is an integer not less than 1.

[0064] In operation S430, security policies are set for p authenticated special terminals to obtain q special terminals with agreed policies; where q is an integer not less than 1.

[0065] In operation S440, according to the preset data processing stream, q special terminals with agreed policies communicate with the core network of the gateway, so that k ordinary terminals can obtain the network services corresponding to the core network of the gateway through the air base station and the q special terminals with agreed policies based on the preset data processing stream; where k is an integer not less than 1.

[0066] It should be noted that a standard terminal refers to a common terminal device used by ground users. These are various electronic devices with a display screen that support web browsing, including but not limited to smartphones, tablets, laptops, and desktop computers. A special terminal, on the other hand, is a terminal device modified from a standard terminal, featuring specially pre-defined service / signaling flows. It connects the core network of the airborne base station and the gateway, and is responsible for network communication between the airborne base station and the gateway.

[0067] In operation S410, a connection is established between the airborne base station and the terminal through a preset connection method, and the corresponding special terminal is identified. The airborne base station can perform unified scheduling of special terminals and ordinary terminals, dynamically allocate time and frequency resources, and improve network service efficiency. The preset connection method includes, but is not limited to, any one of the first path connection method and the second path connection method.

[0068] In S420 operation, after the airborne base station identifies a special terminal, it performs two-way authentication with the terminal. Two-way authentication primarily focuses on verifying the terminal's identity, ensuring that only authorized terminals can access the airborne base station. It involves both user authentication and network authentication, aiming to prevent unauthorized users from occupying network resources or accessing unauthorized networks. Two-way authentication mechanisms, such as AKA (Authentication and Key Agreement), are widely used in 3G UMTS, EPS, and IMS networks, using the correctness of digital signatures to ensure that users accessing the system are authorized.

[0069] In S430 operation, the security policies of the over-the-air base station and the authenticated special terminals need to be agreed upon in advance by both parties. These security policies can broadly encompass the definition and implementation of a series of rules, measures, and action plans to protect network system and data security. Security policies include steps such as risk assessment, goal setting, policy formulation, deployment and implementation, training and awareness building, as well as regular review and updates. The purpose of agreeing on a security policy between the two parties is to ensure the confidentiality, integrity, and availability of the network system, preventing unauthorized access, data breaches, malicious attacks, and other security risks. The implementation of security policies involves measures such as network access control, firewall settings, logging, auditing, and monitoring, improving network security through a range of technical and non-technical means.

[0070] Security policies include one or more of the following: physical security policies, access control policies, firewall control, information encryption policies, and network security management policies.

[0071] Physical security strategies aim to protect hardware devices such as airborne base stations and special terminals, as well as communication links, from natural disasters, human sabotage, and wiretapping attacks.

[0072] Access control policies ensure that network resources are not used or accessed illegally, and are one of the core strategies for network information security.

[0073] Firewall control policies protect against external attacks by controlling inbound and outbound bidirectional communication and using monitoring mechanisms at the network boundary to isolate internal and external networks.

[0074] Information encryption strategies are used to protect data, files, passwords, and control information within the network, as well as to protect data transmitted over the network.

[0075] Network security management strategies are used to determine the level and scope of security management, formulate relevant network usage procedures and personnel management systems, and develop network system maintenance and emergency response measures.

[0076] According to embodiments of this disclosure, the preset data processing flow includes at least one of a service flow and a signaling flow.

[0077] Figure 5 The illustration schematically shows a service flow diagram of a typical terminal in a network communication method for an airborne base station according to an embodiment of the present disclosure.

[0078] Figure 6 The diagram illustrates a signaling flow diagram of a typical terminal for a network communication method of an airborne base station according to an embodiment of the present disclosure.

[0079] In S440 operation, the airborne base station communicates with the gateway's core network using a special terminal, according to... Figure 5 and Figure 6 The service flow / signaling flow allows ordinary terminals to obtain the corresponding network services. It's worth noting that special terminals are modified from ordinary terminals so that their service flow / signaling flow differs from that of ordinary terminals, making them unable to provide the same services as ordinary terminals. Figure 5 and Figure 6 The transmission process of services / signaling in the system.

[0080] like Figure 5As shown, the service layers traversed by the service flow of a regular terminal include APP, PDCP, RLC, MAC, and PHY. The service layers traversed by the service flow of a base station include PDCP, RLC, MAC, and PHY. The service layers traversed by the service flow of a special terminal include PDCP, RLC, MAC, PHY, GTPU, UDP, and IP. The service layers traversed by the core network service flow of a gateway include GTPU, UDP, and IP.

[0081] like Figure 6 As shown, the signaling flow of a regular terminal traverses the following service layers: NAS, RCC, PDCP, RLC, MAC, and PHY. The signaling flow of a base station traverses the following service layers: RCC, PDCP, RLC, MAC, and PHY. The signaling flow of a special terminal traverses the following service layers: PDCP, RLC, MAC, PHY, S1AP, SCTP, and IP. The signaling flow of a gateway's core network traverses the following service layers: NAS, S1AP, SCTP, and IP.

[0082] APP, PDCP, RLC, MAC, PHY, GTPU, UDP, IP, NAS, RCC, S1AP, and SCTP represent different layers or protocols in the fields of computer networks and communications. These protocols and layers together form the cornerstone of modern computer networks and communication systems, ensuring the correct transmission and processing of data.

[0085] RLC: Radio Link Control, responsible for managing the establishment, maintenance, and release of wireless links in a wireless communication system, as well as the reliable transmission of data.

[0086] MAC: Medium Access Control, located at the data link layer of the OSI model, is responsible for establishing and dismantling data links between devices and computer networks, encapsulating and decapsulating frames, and detecting errors.

[0087] PHY: Physical Layer, is the lowest layer in the OSI model, responsible for the physical transmission of data, including voltage, cable specifications, and data bit synchronization.

[0088] GTPU: GPRS Tunneling Protocol User Plane, is the user plane portion of the GPRS tunneling protocol used to transmit user data in mobile networks.

[0089] UDP: User Datagram Protocol, is a connectionless transport layer protocol in the TCP / IP protocol suite used to send data packets over a network.

[0090] IP: Internet Protocol, is one of the core protocols of the TCP / IP protocol suite, used to implement packet routing and forwarding functions at the network layer.

[0091] NAS: NAS (Non-Access Stratum) is part of the protocol stack associated with wireless access networks, located at the access layer.

[0092] RRC: RRC (Radio Resource Control) is a layer in the wireless communication protocol stack, mainly responsible for the control and configuration of wireless resources.

[0093] S1AP: S1AP (S1 Application Protocol) is a protocol used for control plane signaling in LTE systems.

[0094] SCTP: SCTP (Stream Control Transmission Protocol) is a transport layer protocol that provides reliable data transmission.

[0095] 4G / 5G signaling and service flows mainly involve signaling transmission and data processing in LTE / NR networks, including voice and data services. Signaling flows are primarily responsible for network control and communication, while service flows involve the actual data transmission and processing.

[0096] Signaling flow: Signaling flow mainly involves the coordination and control between different network elements, ensuring that the interfaces between communication devices can correctly and effectively transmit control information. This includes processes such as authentication, authorization, and accounting, as well as mobility management and session management, to ensure smooth communication. Signaling flow also involves PLMN (Public Land Mobile Network) identification, base station identification, terminal identification, etc., all of which are for correct routing and identification within the network.

[0097] Service flow: Service flow mainly involves the actual data transmission and processing, including voice and data services. With technological advancements, voice services in LTE networks are increasingly using packet switching technologies, including VoLTE, enabling voice services to be transmitted over data networks, improving communication efficiency and flexibility. Service flow also includes sending and receiving SMS messages, as well as processing data services such as video streaming and file transfer.

[0098] Signaling flow and service flow together form the foundation of LTE / NR network communication. Signaling flow ensures the effectiveness of communication control and management, while service flow is responsible for the actual data transmission and processing. The two work together to provide users with stable and efficient communication services, enabling the communication system to effectively transmit and process data and achieve a smooth communication experience.

[0099] According to embodiments of this disclosure, in operation S410, a connection is established with m terminals based on a preset connection method to identify n special terminals. The connection and identification of special terminals can be achieved by operation S4101 or operation S4102.

[0100] In operation S4101, based on the first path connection method, RRC connections are established with m terminals to identify n special terminals.

[0101] The first path connection method is to establish an RRC connection to achieve interconnection between the air base station and the terminal, as well as the identification of special terminals.

[0102] In operation S4102, based on the second path connection method, communication is established with a special terminal among m terminals through the built-in core network of the air base station to identify n special terminals.

[0103] The second connection method involves integrating core network functions into an airborne base station. This utilizes the built-in core network of the airborne base station to communicate with a special terminal, enabling interconnection between the airborne base station and the special terminal, as well as the identification of the special terminal. It should be noted that the built-in core network of the airborne base station can integrate all or some of the core network's functions.

[0108] When operating the S720, based on the RRC establishment request, n special terminals are identified, and RRC connection setup response messages are sent to m terminals so that the m terminals receive the corresponding RRC connection setup response messages and send an RRC setup completion reply message to the air base station.

[0109] When operating the S730, receive the RRC setup completion response message and establish RRC connections with m terminals.

[0110] like Figure 8 As shown, the airborne base station and the special terminal can establish an RRC connection through the RRC procedure. This is achieved using the messages RRCSetupRequest, RRC Setup, and RRC SetupComplete, which identify the special terminal during the connection establishment process. Since the connection is established through the RRC procedure in the first path connection method, the airborne base station does not require core network functionality. Therefore, after establishing the RRC connection between the special terminal and the airborne base station using the first path connection method, the special terminal will not send any NAS messages (Core Network NAS messages are a message type in the 5G core network used to transmit information between different nodes in the core network to achieve various network functions and session management).

[0111] Radio Resource Control (RC) connections are wireless communication technologies that establish and maintain connections between terminal devices and network infrastructure, enabling efficient and stable data transmission. They are a key factor in ensuring the quality of communication services, primarily transmitting control signals and user data. This connection not only ensures the quality and efficiency of wireless communication but also allows users to enjoy stable and high-quality communication services. The implementation of RRC connections relies on a series of complex protocols and algorithms, including admission control, handover control, and power control. These technologies work together to maximize the use of limited wireless network resources while meeting service quality requirements, thereby improving service capacity and resource utilization.

[0112] RRC SetupRequest is an important signaling message in 5G communication, used by a terminal to request the establishment of an RRC connection from the airborne base station. This request carries the reason for RRC establishment and the terminal's identifier, indicating to the airborne base station that the terminal wishes to establish an RRC connection. The RRC SetupRequest message is transmitted via the CCCH (Common Control Channel). Through this process, the terminal can establish communication with the airborne base station, thereby completing subsequent network access and data processing.

[0113] Furthermore, sending the RRC SetupRequest message is a crucial step for a terminal to connect to the wireless network. After successfully decoding the SSB (Synchronization Sequence Block) and obtaining downlink synchronization, the terminal must execute the Random Access (RACH) procedure to establish uplink synchronization and an RRC connection. MSG3 is the RRC SetupRequest. This procedure includes multiple steps, such as random access preamble transmission, random access response, uplink scheduling transmission (i.e., RRC SetupRequest), and contention resolution, ultimately completing the establishment of the RRC connection.

[0114] RRC Setup is a step in the Radio Resource Control (RRC) protocol, representing the network's response to an RRC request initiated by a User Equipment (UE). This setup message is structured to provide detailed configurations required for communication between the UE and the network, covering aspects such as radio bearer establishment, cell group configuration, and specific cell configurations for uplink and downlink communication channels. In the RRC Setup message, uplink and downlink configurations are achieved through a series of parameters and settings that determine how data is transmitted between the UE and the network.

[0115] The RRC Setup message is a response from the network to an RRC request initiated by the terminal device, used to configure various resources required for communication between the UE and the network. In addition, the RRC Setup message also involves confirmation of resource allocation between the UE and the network, including confirmation of the allocated resources and related reply information.

[0116] The RRC SetupComplete message is a confirmation response from the user equipment (UE) to the RRC SETUP message sent by the network side. This process involves the allocation and confirmation of radio resources. The terminal confirms the allocated resources in the response message and replies with the contents of its 5G_S_TMSI_Value Part 2. This message carries selectedPLMN-Identity, registeredAMF, snssai-list, and NAS information, which are used for context establishment and registration requests. After receiving this message, the base station will perform authentication and registration procedures with the core network based on the AMF identifier.

[0117] The RRC SetupComplete process is part of the Radio Resource Control (RRC) protocol in 5G systems. Its main function is to control or configure all radio resources for lower layers (such as PHY, MAC, RLC, PDCP), thereby ensuring communication between the terminal and the base station. This process involves the exchange of multiple messages, including RRC connection requests and RRC connection settings, and its success or failure directly affects whether the user equipment can successfully establish a communication session.

[0118] Figure 9 The diagram illustrates an ID identification flowchart of a network communication method for an airborne base station according to an embodiment of the present disclosure.

[0119] like Figure 9 As shown, according to an embodiment of this disclosure, in operation S720, a request is established based on RRC, and n special terminals are identified, including operations S910-S920.

[0120] When operating S910, obtain the user IDs corresponding to the RRC establishment requests of m terminals.

[0121] When operating the S920, n special terminals are identified based on the user IDs of m terminals.

[0122] During the RRC connection process, special terminals inform the air base station of their user ID via an RRC Setup Request. Figure 8 The InitialUE-Identity (in the system) is used by the airborne base station to identify the terminal as a special terminal. It should be noted that the user ID is an agreement that has been made between the base station and the special terminal at the underlying level.

[0123] Figure 10 The diagram illustrates a second path connection flowchart of a network communication method for an airborne base station according to an embodiment of the present disclosure.

[0124] Figure 11The diagram schematically illustrates a second path interaction diagram of a network communication method for an airborne base station according to an embodiment of the present disclosure.

[0125] like Figure 10 As shown, according to an embodiment of this disclosure, in operation S4102, based on the second path connection method, communication is made with a special terminal among m terminals through the built-in core network of the air base station to identify the special terminals among the n special terminals, including operations S1010-S1030.

[0126] In operation S1010, registration requests from m terminals are received.

[0127] In operation S1020, the built-in core network of the airborne base station is used to receive the registration request of a special terminal among m terminals, and send an identification request to the special terminal among m terminals, so that the special terminal among m terminals sends an identification response to the built-in core network of the airborne base station.

[0128] When operating the S1030, the built-in core network of the airborne base station is used to receive identification responses and identify n special terminals.

[0129] In embodiments of this disclosure, the airborne base station integrates some or all of the core network functions, which communicate only with specific terminals. For example... Figure 11 The interaction process allows the core network integrated into the air base station to obtain the UE ID (the UE ID of a special terminal is agreed upon in advance by both the air base station and the special terminal). The UE ID is the device identification identifier used to identify which terminals are special terminals.

[0130] like Figure 11 As shown, the terminal sends a registration request to the air base station. The air base station's built-in core network receives the registration request from the special terminal and sends an identity request to the special terminal among m terminals. The special terminal then sends an identity response to the air base station's built-in core network. The identity response contains the UE ID of the special terminal.

[0131] A registration request is a request sent by a device to a network or service when it wants to join the network or service. It means a request to be added to the network or service in order to communicate or use the service. This request is typically established by the network or service provider to control and manage users of the network or service, thereby ensuring the security and reliability of the network or service.

[0132] In practical applications, Registration Requests play a crucial role. First, they can be used to identify and verify device identities. Within a network or service, each device has a unique identifier. Through a Registration Request, the network or service provider can identify the device and verify its legitimacy. This prevents unauthorized devices from joining, ensuring network or service security. Second, Registration Requests allow network or service providers to obtain device information. Before a device joins a network or service, it typically needs to provide necessary information such as its type, function, and the user it belongs to. This information allows the network or service provider to categorize and manage devices, better meeting user needs. Furthermore, Registration Requests can be used to control and manage device access permissions. In networks or services requiring payment or authorization, Registration Requests allow network or service providers to authorize devices, thus controlling their access. This ensures network or service revenue while protecting user rights. Finally, Registration Requests can also enable dynamic management of networks or services. As networks and services evolve, new devices may join, or older devices may be decommissioned. Through a Registration Request, a network or service provider can obtain device information in real time, thereby adjusting the network or service configuration in a timely manner to ensure the stability and reliability of the network or service.

[0133] An Identity Request, or Identity Authentication Request, is a part of authentication used to confirm and verify the identity of participants during communication. During communication, an Identity Request involves multiple steps and message exchanges to ensure secure and reliable communication. These requests typically include user-provided credentials to identify the user. Using these credentials, the system can confirm the user's identity and then authorize them; this is a crucial step in maintaining session state and user authorization. Simply put, authentication verifies a user's legitimacy by verifying their identity, while authorization determines the resources a user can access or the actions they can perform based on the verification result.

[0134] In 5G communication systems, the Identity Request process involves assigning each user a 5G User Permanent Identifier (SUPI) and a temporary identifier to support user confidentiality. The allocation and management of these identifiers are crucial for ensuring communication security. These identifiers allow network operators to identify, locate, and track users, but it is also essential to protect user privacy and prevent the leakage of identity information.

[0135] Identity Response, in network communication, refers to the network identification response or identity response. The identification process involves sending an identity request message to the over-the-air base station. Upon receiving this message, the specific terminal initiates an identity response message to provide its user identification to the network. The identity response from the specific terminal to the over-the-air base station provides its identity information so that the network can verify and authorize it. Identity information plays a crucial role in the communication process, ensuring the accuracy and security of communication.

[0136] According to embodiments of this disclosure, the airborne base station and a special terminal are connected wirelessly.

[0137] According to embodiments of this disclosure, the special terminal is connected to the core network of the gateway via wired communication; or the special terminal is connected to the core network of the gateway via wireless communication.

[0138] According to embodiments of this disclosure, the airborne base station is connected to a regular terminal via wireless communication.

For example... Figure 12 As shown, a special terminal is introduced to enable the drone to establish a wireless connection between the airborne base station and the ground. The special terminal and the gateway's core network can be connected via a wired or wireless network. Wired networks establish communication through fiber optic cables, electrical cables, or network cables, while wireless networks can connect via wireless data links, digital wireless links, or satellite links.

[0140] Compared to existing technologies, such as Figure 1 The wireless communication connection disclosed herein eliminates the need to integrate a satellite terminal on the drone, thereby reducing the power consumption and weight of the communication payload on the drone. Compared to existing technologies, such as... Figure 2The special terminal disclosed herein is a specially improved version of a regular terminal, featuring simple equipment and easy deployment. This allows regular terminals to quickly obtain network services through an airborne base station and the special terminal. Utilizing the special terminal, the airborne base station for the UAV does not need to integrate a satellite terminal, thus reducing the power consumption and weight of the communication payload on the UAV. The special terminal is simple to install and easy to deploy between the airborne base station and the core network, expanding the application scenarios of the airborne base station. Furthermore, it enables unified scheduling of the special terminal and regular terminals by the airborne base station, dynamically allocating time and frequency resources, and improving the efficiency of regular terminals in obtaining network services.

[0141] In the embodiments of this disclosure, communication between the airborne base station and the core network of the gateway requires complex equipment, which is not conducive to deployment. By implementing the embodiments of this disclosure, based on a preset connection method, connections are established with m terminals to identify n special terminals. These terminals include ordinary terminals and special terminals. Bidirectional authentication is performed on the n special terminals to obtain p authenticated special terminals. Security policies are set corresponding to the p authenticated special terminals to obtain q special terminals with agreed-upon policies. Based on a preset data processing flow, the q special terminals with agreed-upon policies communicate with the core network of the gateway, enabling k ordinary terminals to obtain network services corresponding to the core network of the gateway through the airborne base station and the q special terminals with agreed-upon policies, based on the preset data processing flow. This allows ordinary terminals to quickly obtain network services through the airborne base station and special terminals. Using special terminals, the airborne base station of the UAV does not need to integrate a satellite terminal, thereby reducing the power consumption and weight of the communication payload on the UAV. The special terminal equipment is simple and easy to deploy between the airborne base station and the core network, expanding the application scenarios of the airborne base station. In addition, it can enable airborne base stations to uniformly schedule special terminals and ordinary terminals, dynamically allocate time and frequency resources, and improve the efficiency of ordinary terminals in obtaining network services.
