Description

Technical Field

[0001] The present disclosure relates to the field of communications, and more particularly to aerial base station communications, and more particularly to a network communication method, device, electronic device, computer-readable storage medium, and computer program product for an aerial base station. Background Art

[0002] ‌An aerial base station is an aerial facility that can provide communication services. With the development of technology, the application scenarios of aerial base stations are becoming more and more extensive. Aerial base stations are used to expand communication coverage or provide stable communication services in a specific area. Aerial base stations can be temporary communication equipment carried by drones. Aerial base stations provide communication services to ground users, especially in natural disasters, remote areas or special events, to provide emergency communication support. The aerial base station on the drone is an innovative communication solution. It can not only meet the communication recovery needs in emergency situations such as natural disasters, but also play an important role in promoting the popularization of global network access and improving the technology and application of the low-altitude economy. For example, in the case of power outages and network outages in the disaster area, emergency communication services can be quickly deployed through aerial base stations carried by drones to provide necessary communication support for rescue workers and residents in the disaster area.

[0003] The aerial base stations (4G or 5G base stations) carried by existing drones usually achieve network communication connections through both wired and wireless solutions. Figure 1 The wireless communication connection diagram of the aerial base station is schematically shown. Figure 1 As shown in the figure, the aerial base station is on the drone, and there is also a satellite terminal. The base station is connected to the ground core network through the satellite terminal. The disadvantage is that the communication payload on the drone has high power consumption and heavy weight, and can only rely on satellites for backhaul, which cannot complete communication conveniently and efficiently. Figure 2 The wired communication connection diagram of the aerial base station is schematically shown. Figure 2 As shown in the figure, a tethered drone is used, and the RRU (Remote Radio Unit, a remote control unit, is one of the devices of the mobile base station) or the aerial base station is placed on the tethered drone, and the aerial base station (or RRU) and the ground equipment are connected through an optical-electrical hybrid cable, and the ground equipment is then connected to the ground core network through a wired network (optical fiber or network cable) or a satellite module. The disadvantage is that due to the connection between the ground equipment and the drone, the flight position and height of the drone are limited, and the equipment is complex, which is not conducive to deployment.

[0046] It should be noted that the network communication method and device of the aerial base station provided in the embodiments of the present disclosure can be applied to the communication field, the aerial base station communication technology field, or any technical field other than the above-mentioned technical fields. The application field of the network communication method and device of the aerial base station provided in the embodiments of the present disclosure is not specifically limited.

[0047] An embodiment of the present disclosure provides a network communication method for an aerial base station.

[0048] Figure 3 An application scenario diagram of a network communication method, device, electronic device, computer-readable storage medium, and computer program product for an aerial base station according to an embodiment of the present disclosure is schematically shown.

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

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

[0051] The common terminal devices 301, 302, 303 may be various electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, and the like.

[0052] The base station 305 can provide communication services for the common terminal devices 301, 302, and 303 of the ground users, and provide support (for example only) for the websites browsed by the users using the common terminal devices 301, 302, and 303 through the core network of the base station 305, the special terminal device 307, and the gateway 309. The received data such as the user request is analyzed and processed, and the processing results (such as the web page, information, or data obtained or generated according to the user request, etc.) are fed back to the corresponding terminal device.

[0053] like Figure 3 As shown, the network 306 is used to provide a medium for a communication link between the special terminal device 307 and the base station 305. The network 306 realizes the connection between the special terminal device 307 and the base station 305 by using a wireless communication link.

[0054] The special terminal device 307 is a terminal device improved from an ordinary terminal and having a special preset service flow / signaling flow. It connects the base station 305 and the gateway 309 and is responsible for the network communication between the base station 305 and the gateway 309.

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

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

[0057] It should be noted that the network communication method of the air base station provided in the embodiment of the present disclosure can generally be executed by the base station 305. Accordingly, the network communication device of the air base station provided in the embodiment of the present disclosure can generally be set in the base station 305. The network communication method of the air base station provided in the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the base station 305 and can communicate with the ordinary terminal devices 301, 302, 303 and / or the base station 305. Accordingly, the network communication device of the air base station provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the base station 305 and can communicate with the ordinary terminal devices 301, 302, 303 and / or the base station 305.

[0058] It should be understood that Figure 3 The number of common terminal devices, special terminal devices, networks, gateways and base stations in the embodiment is only for illustration. Any number of common terminal devices, special terminal devices, networks, gateways and base stations may be provided according to implementation requirements.

[0059] The following will be based on Figure 3 The scene described by Figure 4 to Figure 12 The network communication method of the aerial base station of the disclosed embodiment is described in detail.

[0060] Figure 4 The flowchart of the network communication method of the aerial base station according to the embodiment of the present disclosure is schematically shown.

[0061] like Figure 4 As shown, the network communication method of the aerial base station of 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; wherein the terminals include common terminals and special terminals; wherein m and n are integers not less than 1.

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

[0064] In operation S430, security policies corresponding to the p special terminals that have passed authentication are set to obtain q special terminals with agreed policies; wherein q is an integer not less than 1.

[0065] In operation S440, according to the preset data processing flow, q special terminals of the agreed strategy are used to 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 of the agreed strategy based on the preset data processing flow; wherein k is an integer not less than 1.

[0066] It should be noted that ordinary terminals are ordinary terminal devices of ground users, and are various electronic devices with display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptops and desktop computers, etc. Special terminals are terminal devices with special preset service flows / signaling flows improved from ordinary terminals, connecting the core network of the air base station and the gateway, and are responsible for the network communication between the air base station and the gateway.

[0067] In operation S410, a connection is established between the air base station and the terminal through a preset connection method, and the corresponding special terminal is identified. The air base station can realize 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 operation S420, after the air base station identifies the special terminal, the air base station performs two-way authentication with the special terminal. The two-way authentication mainly focuses on verifying the identity of the special terminal to ensure that only authorized special terminals can access the air base station. It involves two aspects: user authentication and network authentication, and aims to prevent illegal users from occupying network resources or accessing illegal networks. Two-way authentication mechanisms, such as AKA (Authentication and Key Agreement), are widely used in 3G UMTS, EPS, IMS and other networks, and ensure that users accessing the system are authorized by verifying the correctness of digital signatures.

[0069] In operation S430, the security policy of the aerial base station and the special terminal that has passed the authentication needs to be agreed upon in advance by both parties. The security policy can broadly involve the definition and implementation of a series of rules, measures and action plans to protect the network system and data security. The security policy includes risk assessment, goal setting, policy formulation, deployment implementation, training and awareness raising, as well as regular review and update steps. The purpose of the agreed security policy is to ensure the confidentiality, integrity and availability of the network system, and prevent unauthorized access, data leakage, malicious attacks and other security risks. The implementation of the security policy involves measures such as network access control, firewall settings, logging, auditing and monitoring, and improves the security of the network through a series of technical and non-technical means.

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

[0071] ‌Physical security strategies are designed to protect hardware equipment and communication links such as aerial base stations and special terminals from natural disasters, human damage, and wiretapping attacks.

[0072] Access control strategy ensures that network resources are not illegally used and accessed, and is one of the core strategies of network information security.

[0073] Firewall control strategies control inbound and outbound bidirectional communications and isolate internal and external networks through monitoring mechanisms at the network boundary to resist external attacks.

[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 formulate maintenance and emergency measures for network systems.

[0076] According to an embodiment of the present disclosure, the preset data processing flow includes at least one of a business flow and a signaling flow.

[0077] Figure 5 A business flow diagram of a common terminal of a network communication method of an aerial base station according to an embodiment of the present disclosure is schematically shown.

[0078] Figure 6 The signaling flow chart of a common terminal of the network communication method of the aerial base station according to the embodiment of the present disclosure is schematically shown.

[0079] In operation S440, the air base station communicates with the core network of the gateway using a special terminal. Figure 5 and Figure 6 The service flow / signaling flow of the special terminal allows ordinary terminals to obtain corresponding network services. It is worth noting that the special terminal is improved on the basis of the ordinary terminal so that the service flow / signaling flow of the special terminal is different from that of the ordinary terminal, and the ordinary terminal cannot achieve Figure 5 and Figure 6 The transmission process of services / signaling in.

[0080] like Figure 5As shown in the figure, the service layers through which the service flows of ordinary terminals flow include APP, PDCP, RLC, MAC, and PHY. The service layers through which the service flows of base stations flow include PDCP, RLC, MAC, and PHY. The service layers through which the service flows of special terminals flow include PDCP, RLC, MAC, PHY, GTPU, UDP, and IP. The service layers through which the service flows of the core network of the gateway flow include GTPU, UDP, and IP.

[0081] like Figure 6 As shown in the figure, the layer services through which the signaling flow of ordinary terminals flows include NAS, RCC, PDCP, RLC, MAC, and PHY. The layer services through which the signaling flow of base stations flows include RCC, PDCP, RLC, MAC, and PHY. The layer services through which the signaling flow of special terminals flows include PDCP, RLC, MAC, PHY, S1AP, SCTP, and IP. The layer services through which the signaling flow of the core network of the gateway flows include NAS, S1AP, SCTP, and IP.

[0082] APP, PDCP, RLC, MAC, PHY, GTPU, UDP, IP, NAS, RCC, S1AP, SCTP represent different layers or protocols in the field of computer networks and communications.

[0105] Figure 8 A first path interaction diagram of a network communication method for an aerial base station according to an embodiment of the present disclosure is schematically shown.

[0106] like Figure 7As shown, according to an embodiment of the present disclosure, in operation S4101, based on the first path connection method, RRC connections with m terminals are established to identify n special terminals, including operations S710-S730.

[0107] In operation S710, RRC establishment requests of m terminals are received.

[0108] In operation 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 corresponding RRC connection setup response messages and send RRC setup completion response messages to the air base station.

[0109] In operation S730, an RRC setup completion response message is received, and an RRC connection with m terminals is established.

[0110] like Figure 8 As shown, the air base station and the special terminal can establish an RRC connection through the RRC process, using the messages RRCSetupRequest (RRC establishment request), RRC Setup (RRC connection setup response) and RRC SetupComplete (RRC setup completion response) to establish the RRC connection between the air base station and the terminal, and in the process of establishing the RRC connection, identify the special terminal. Since in the first path connection method, the connection is achieved by establishing the RRC process, the air base station does not need the core network function and has no core network function. After the RRC connection is established between the special terminal and the air base station using the first path connection method, the special terminal will not send any NAS message in the subsequent communication process (Core network NAS message is a message type in the 5G core network, which is used to transmit information between different nodes in the core network to achieve various network functions and session management).

[0111] RRC (Radio Resource Control) connection is a wireless communication technology that achieves efficient and stable data transmission by establishing and maintaining the connection between terminal equipment and network infrastructure. It is a key factor in ensuring the quality of communication services. Its main purpose is to transmit control signals and user data. This connection not only ensures the quality and efficiency of wireless communication, but also enables users to enjoy stable and high-quality communication services. The implementation of RRC connection relies on a series of complex protocols and algorithms, including admission control, switching control, power control, etc. These technologies work together to ensure that limited wireless network resources are used to the maximum extent possible while meeting service quality requirements, and to improve service capacity and resource utilization.

[0112] RRC SetupRequest is an RRC setup request. ‌RRC SetupRequest‌ is an important signaling in 5G communication, which is used by the terminal to request the air base station to establish an RRC connection. This request carries the reason for the RRC establishment and the terminal's identity, and is the way for the terminal to indicate to the air base station that it wants to establish an RRC connection. The transmission channel of the RRC SetupRequest message is CCCH (common control channel). Through this process, the terminal can establish communication with the air base station, and then complete subsequent network access and data processing.

[0113] In addition, the sending of the RRC SetupRequest message is a key step for the terminal in the network to connect to the wireless network. After successfully decoding the SSB (synchronization signal block) to obtain downlink synchronization, in order to establish uplink synchronization and RRC connection, the terminal must perform a random access (RACH) process, in which MSG3 is the RRC SetupRequest. This process includes multiple steps, such as random access preamble transmission, random access response, uplink scheduling transmission (ie, RRC SetupRequest) and contention resolution, and finally completes the establishment of the RRC connection.

[0114] RRC Setup is a link in the Radio Resource Control (RRC) protocol and is the network's response to an RRC request initiated by a user equipment (UE). The structure of this setup message is designed to provide the detailed configuration required for communication between the UE and the network, covering multiple aspects such as radio bearer establishment, cell group configuration, and special cell configuration for uplink and downlink communication channels. In the RRCSetup message, the configuration of the uplink and downlink is 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 the network's response to an RRC request initiated by the terminal device, and is used to configure various resources required for communication between the UE and the network. In addition, the RRC Setup message also involves resource allocation confirmation between the UE and the network, including confirmation of allocated resources and related information of the reply.

[0116] The RRC SetupComplete message is a confirmation response from the user equipment to the RRC SETUP message sent by the network side. This process involves the allocation and confirmation of wireless resources, in which the terminal confirms the allocated resources in the response message and replies with the content of its 5G_S_TMSI_Value Part2. 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 the authentication and registration process with the core network based on the AMF identifier.

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

[0118] Fig. 9 The ID identification flow chart of the network communication method of the aerial base station according to an embodiment of the present disclosure is schematically shown.

[0119] like Fig. 9 As shown, according to an embodiment of the present disclosure, in operation S720, based on the RRC establishment request, n special terminals are identified, including operations S910-S920.

[0120] In operation S910, user IDs corresponding to RRC establishment requests of m terminals are obtained.

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

[0122] During the RRC connection process, the special terminal informs the air base station of its user ID through the RRC Setup Request ( Figure 8 InitialUE-Identity in the air base station identifies the terminal as a special terminal through the ID. It should be noted that the user ID is an agreement between the base station and the special terminal at the bottom layer.

[0123] Fig.10 A second path connection flow chart of the network communication method of the aerial base station according to an embodiment of the present disclosure is schematically shown.

[0124] Fig.11A second path interaction diagram of the network communication method of the aerial base station according to an embodiment of the present disclosure is schematically shown.

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

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

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

[0128] In operation S1030, the built-in core network of the air base station is used to receive the identity recognition response and identify n special terminals.

[0129] In the embodiments of the present disclosure, the aerial base station integrates part or all of the core network functions, and the core network communicates only with special terminals. Fig.11 The core network integrated into the aerial base station can obtain the UE ID (the UE ID of the special terminal is agreed upon in advance by the aerial base station and the special terminal). The UE ID is the device identity and is used to identify which terminals are special terminals.

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

[0131] Registration Request is a request sent to a network or service when a device wants to join a network or service during communication. It means requesting to be added to the network or service in order to communicate or use the service. This request is usually set up by the network or service provider in order to control and manage the users of the network or service, thereby ensuring the security and reliability of the network or service.

[0132] In practical applications, Registration Request plays a very important role. First, it can be used to identify and verify the identity of the device. In a network or service, each device has a unique identity. Through Registration Request, the network or service provider can identify the identity of the device and verify its legitimacy. This can prevent the addition of illegal devices and ensure the security of the network or service. Secondly, through Registration Request, the network or service provider can obtain the information of the device. Before a device joins a network or service, it is usually necessary to provide some necessary information, such as the type, function, and user of the device. With this information, the network or service provider can classify and manage the devices to better meet the needs of users. In addition, Registration Request can also be used to control and manage the use rights of the device. In some networks or services that require payment or authorization to use, through Registration Request, the network or service provider can authorize the device to control its use rights. This can ensure the benefits of the network or service, while also protecting the rights and interests of users. In addition, Registration Request can also be used to implement dynamic management of networks or services. With the development of networks and services, new devices may join or old devices may withdraw. Through Registration Request, the network or service provider can obtain device information in real time, so as to adjust the configuration of the network or service in time to ensure the stability and reliability of the network or service.

[0133] Identity Request is an identity identification request, which is part of identity authentication and is used to confirm and verify the identity of participants during the communication process. During the communication process, Identity Request involves multiple steps and message exchanges to ensure the security and reliability of communication. These requests usually include credentials provided by the user to identify the user. With these credentials, the system can confirm the identity of the user and then authorize him, which is a key step in maintaining session state and user authorization. In simple terms, identity authentication is to confirm the legitimacy of the user by verifying the user's identity, while authorization is to determine the resources that the user can access or the operations that can be performed based on the verification results.

[0134] In the 5G communication system, the Identity Request process includes the allocation of a 5G User Permanent Identifier (SUPI) to each user and the allocation of a temporary identifier to support user confidentiality protection. The allocation and management of these identifiers is an important part of ensuring communication security. Through these identifiers, network operators can identify, locate and track users, but at the same time, they also need to pay attention to protecting user privacy and avoiding the leakage of identity information.

[0135] Identity Response is an identity response. In network communication, Identity Response refers to a network identification response or identity response. The identification procedure is to initiate an identification request message to the air base station. After receiving the message, the special terminal initiates an identification response message to provide its user identification to the network. The special terminal responds to the identity request from the air base station to provide its identity information for verification and authorization by the network. Identity information plays an important role in the communication process to ensure the accuracy and security of communication.
