[0023] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] According to an embodiment of the present application, a method embodiment of a method for managing an address pool is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0026] Figure 1 is a flow chart of a method for managing an address pool according to an embodiment of the present application, such as Figure 1 As shown, the method includes the following steps:

[0027] Step S102: Receive a first session message.

[0028] According to some optional embodiments of the present application, the first session message is a session message between a network element and a terminal, wherein the session message between the network element and the terminal refers to the message exchanged between the network element and the terminal during the communication process. These session messages include request messages and response messages. A request message is a message sent by a terminal to a network element, used to request a certain operation or service from the network element. A request message generally contains information such as the request method, path, and parameters, so that the network element can correctly process and respond. A response message is a message sent by a network element to a terminal, used to respond to the terminal's request. A response message generally contains information such as a status code, a response header, and a response body, so that the terminal can perform subsequent processing based on the response result. The content and format of the session message generally follow certain protocol specifications. For example, the request message and response message in the HTTP protocol follow the HTTP protocol specifications. Different protocols may have different session message format and content requirements.

[0029] Step S104: When it is determined that the Internet Protocol address obtained by the terminal is abnormal, determine the flag bit type in the first field of the first session message between the terminal and the network element, wherein the flag bit type is used to determine the network element that allocates the address to the terminal.

[0030] According to other optional embodiments of the present application, when the terminal goes online, the Internet Protocol address obtained is abnormal, for example: the Internet Protocol address allocated by the network element cannot be received. This situation is likely caused by insufficient address resources in the address pool corresponding to the network element.

[0031] A flag is a binary value that indicates a specific condition or status. Flags are often used to determine and adjust control flow during program execution. A flag can be a single bit or a combination of one or more bits. Flags can indicate various conditions, such as program completion, error occurrence, or the satisfaction of a condition. By checking the value of a flag, the program can take different actions based on the situation.

[0032] Step S106: Determine the target network element causing the Internet Protocol address anomaly based on the flag bit type.

[0033] In some optional embodiments of the present application, when the flag bit is V4 or / and V6, it indicates that the address is allocated by the session management function network element, and the faulty network element is located as the session management function network element; when the flag bit is CHV4 or / and CHV6, it indicates that the address is allocated by the UPF, and the faulty network element is located as the user plane function network element.

[0034] The user plane function network element (UPE) is a key network element in 5G networks, responsible for data transmission and user plane functions. The UPE primarily handles user data transmission, including data encapsulation, decapsulation, routing, and forwarding. It selects appropriate transmission paths and protocols based on network requirements and quality of service (QoS) to ensure reliable data transmission. It controls and manages user data flow based on network traffic conditions, scheduling and optimizing traffic based on network congestion and QoS requirements to ensure network stability and performance. It prioritizes user data based on different QoS requirements, prioritizing and scheduling data based on user needs and network resource availability to ensure the timely and reliable transmission of important data. It protects user data security by encrypting and decrypting data to prevent data leakage and tampering. Furthermore, the UPE can perform traffic monitoring and analysis to promptly detect and prevent network attacks and abnormal behavior. It supports Network Function Virtualization (NFV), virtualizing traditional hardware devices into software entities to improve network flexibility and scalability. Through virtualization technology, user plane functional network elements can dynamically allocate resources according to network needs and quickly deploy and adjust network functions.

[0035] A session management function (SMF) is a device or module responsible for managing and maintaining session status within the network. It typically performs the following functions: Session establishment and termination: When a user initiates a session request, the SMF assigns a unique session identifier and associates it with the user's session information. When the session ends, the SMF releases related resources and clears the session information. Session tracking and maintenance: The SMF records each session's status information, such as its start time, duration, and participant information. This status information can be used to monitor and manage session operations. Session routing and forwarding: Forwards session data to the correct destination based on the session identifier and destination address. The SMF can send session data to the appropriate destination device or module based on preconfigured routing policies. Session security and access control: Ensures session security and confidentiality. The SMF can implement security measures such as authentication, encryption, and access control to protect session data from unauthorized access. Session monitoring and troubleshooting: Monitors session operations and performs troubleshooting when failures or anomalies occur. The session management function network element can collect and analyze session data to identify and solve problems in a timely manner.

[0036] Step S108: When the usage rate of the address resources in the address pool corresponding to the target network element is greater than a preset threshold, the address resources in the address pool are increased.

[0037] As some optional embodiments of the present application, by calling the attribute information of the target network element, the usage and utilization rate of the address resources of the address pool corresponding to the target network element can be determined. When the usage exceeds a preset threshold or the utilization rate exceeds a preset percentage, the address resources in the address pool are expanded.

[0038] According to the above steps, by determining that the Internet Protocol address obtained by the terminal is abnormal, determining the flag bit type in the first field in the first session message between the terminal and the network element, and determining the target network element that caused the Internet Protocol address abnormality based on the flag bit type, and when the usage rate of the address resources in the address pool corresponding to the target network element is greater than the preset threshold, increasing the address resources in the address pool, the purpose of determining the faulty network element that caused the Internet Protocol address abnormality and then expanding the address pool of the faulty network element is achieved, thereby achieving the technical effect of ensuring that the terminal can quickly obtain the Internet Protocol address.

[0039] According to some optional embodiments of the present application, the first address type of the Internet Protocol address obtained by the terminal is determined based on the second field in the first session message; the second address type included in the address pool corresponding to the target network element is obtained; the first address type and the second address type are matched, and when the first address type and the second address type are inconsistent or the first address type is not included in the second address type, a first message for prompting an abnormality in the packet data network type is sent to the terminal.

[0040] Obtain the packet data network type field in the session establishment message based on the packet forwarding control protocol, determine whether the address type requested by the terminal is IPv4, IPv6, or IPv4&IPv6 based on the packet data network type field in the session establishment message, and match it with the IP type supported by the address pool of the network element. If it is determined that the Internet Protocol address type requested by the terminal is incorrect, prompt the terminal that the packet data network type is abnormal.

[0041] According to some optional embodiments of the present application, the first field includes: an Internet Protocol address field corresponding to the terminal in the original data record creation message; the second field includes: a packet data network type field in the session establishment message.

[0042] According to some other optional embodiments of the present application, the flag bit types include: the flag bit types include: a first flag bit and a second flag bit, wherein the first flag bit is used to indicate that the Internet Protocol address of the terminal is allocated by the session management function network element, and the second flag bit is used to indicate that the Internet Protocol address of the terminal is allocated by the user plane function network element.

[0043] In some optional embodiments of the present application, the first flag bit and the second flag bit both include a flag bit corresponding to an IPV4 address and a flag bit corresponding to an IPV6 address.

[0044] Optionally, the first flag bit includes at least: a flag bit corresponding to an IPV4 address and a flag bit corresponding to an IPV6 address, and the second flag bit includes at least: a CHV4 flag bit and a CH V6 flag bit in the 3GPP protocol.

[0045] 3GPP (3rd Generation Partnership Project) is an international standardization organization composed of telecom operators and telecom manufacturers, dedicated to developing and formulating standards for mobile communication technologies. The 3GPP protocol is a series of mobile communication standards developed by the 3GPP organization, including standards for various generations of mobile communication technologies such as 2G, 3G, and 4G. These standards cover aspects such as mobile network architecture, interface protocols, wireless access technology, data transmission, and security. The main goal of the 3GPP protocol is to promote the interoperability and interoperability of global mobile communication systems, enabling equipment and networks from different manufacturers to be compatible with each other. By developing unified standards, the 3GPP protocol ensures that networks from different operators can connect and communicate seamlessly, providing a unified user experience.

[0046] As some optional embodiments of the present application, when the usage rate of the address resources of the address pool corresponding to the target network element is greater than the preset threshold, after increasing the address resources in the address pool, it is also necessary to: determine whether the terminal obtains the Internet Protocol address allocated by the network element.

[0047] According to some other optional embodiments of the present application, the first session message is transmitted based on a packet forwarding control protocol.

[0048] The Packet Forwarding Control Protocol (PFCP) is a protocol for controlling, managing, and monitoring packet forwarding. It is a control plane protocol used in 5G networks, used to transmit control information between the user plane and the control plane. PFCP is primarily used as the protocol interface between the control plane and the user plane to configure and manage packet forwarding policies, load balancing, Quality of Service (QoS), and other related functions. PFCP provides a flexible way to configure and control packet forwarding in the network and supports the deployment of network function virtualization and software-defined networking.

[0049] The main functions of PFCP include: 1. Session management: establishing, modifying, and terminating sessions to control packet forwarding; 2. Traffic processing: defining and configuring packet forwarding policies, load balancing, and quality of service; 3. Network Function Virtualization (NFV) support: supporting the deployment and management of network functions in a virtualized environment; 4. Error handling and fault management: monitoring and managing faults and errors in the network; 5. Security: providing security mechanisms to protect the confidentiality and integrity of packet forwarding control information.

[0050] Figure 2 is a flow chart of another method for managing an address pool according to an embodiment of the present application, such as Figure 2 As shown, the method includes the following steps:

[0051] Step S202: The user plane function network element performs parameter identification on the terminal Internet Protocol address message in the user PFCP session establishment request.

[0052] Figure 3 This is a schematic diagram of the interaction between a terminal and a session management function network element and a user plane function network element according to an embodiment of the present application. The terminal establishes a PFCP session with the user plane function network element through the session management function network element, and the user plane function network element performs parameter identification on the terminal Internet Protocol address message in the user PFCP session establishment request.

[0053] Step S204: For a particular session, the flag bit in the terminal Internet Protocol address message is analyzed. If the flag bit is V4 or V6, it indicates that the address is allocated by the session management function network element, and the faulty network element is located as the session management function network element. If the flag bit is CHV4 or CHV6, it indicates that the address is allocated by the user plane function network element, and the faulty network element is located as the user plane function network element.

[0054] Step S206: Based on the faulty NE located in step S204, the configuration of the faulty NE is obtained and the available ratio of the NE's address pool is analyzed to determine whether it meets the terminal's requirements. The packet data network type field in the PFCP session establishment message is also obtained to confirm whether the terminal's requested address type is IPv4, IPv6, or IPv4 & IPv6. This is then matched against the IP types supported by the NE's configured address pool.

[0055] Step S208: When the analysis result shows that the address pool resources of the faulty network element are insufficient, the expansion configuration is issued to make the address pool resources available; when the analysis result shows that the address type requested by the terminal is not supported, an associated alarm is generated on the user plane functional network element side, prompting the terminal to request an unsupported type and to modify the packet data network type.

A method for managing an address pool, characterized in that: include: receiving a first session message; In a case where it is determined that the Internet Protocol address obtained by the terminal is abnormal, determining a flag bit type in a first field in the first session message between the terminal and the network element, wherein the flag bit type is used to determine the network element that allocates the address to the terminal; Determining, according to the flag bit type, a target network element causing the Internet Protocol address anomaly; When the usage rate of the address resources in the address pool corresponding to the target network element is greater than a preset threshold, the address resources in the address pool are increased.

2. The method according to claim 1, characterized in that include: determining, according to the second field in the first session message, a first address type of the Internet Protocol address acquired by the terminal; Obtaining a second address type included in the address pool corresponding to the target network element; The first address type and the second address type are matched, and if the first address type and the second address type are inconsistent or the second address type does not include the first address type, a first message for prompting abnormality of the packet data network type is sent to the terminal.

3. The method according to claim 2, characterized in that include: The first field includes: creating an Internet Protocol address field corresponding to the terminal in the original data record message; The second field includes: a packet data network type field in a session establishment message.

4. The method according to claim 1, wherein The flag bit type includes: a first flag bit and a second flag bit, wherein the first flag bit is used to indicate that the Internet Protocol address of the terminal is allocated by a session management function network element, and the second flag bit is used to indicate that the Internet Protocol address of the terminal is allocated by a user plane function network element.

5. The method according to claim 4, characterized in that The first flag bit and the second flag bit both include a flag bit corresponding to an IPV4 address and a flag bit corresponding to an IPV6 address.

6. The method according to claim 1, characterized in that When the usage rate of the address resources in the address pool corresponding to the target network element is greater than a preset threshold, after increasing the address resources in the address pool, the method further includes: determining whether the terminal obtains the Internet Protocol address allocated by the network element.

7. The method according to claim 1, characterized in that The first session message is transmitted based on a packet forwarding control protocol.

8. A device for managing an address pool, characterized in that: include: A receiving module, configured to receive a first session message; A first determining module is configured to, when it is determined that the Internet Protocol address obtained by the terminal is abnormal, determine a flag bit type in a first field in the first session message between the terminal and the network element, wherein the flag bit type is used to determine the network element that allocates the address to the terminal; A second determining module is configured to determine a target network element causing the Internet Protocol address anomaly based on the flag bit type; The adding module is used to add address resources in the address pool when the usage rate of the address resources in the address pool corresponding to the target network element is greater than a preset threshold.

9. A non-volatile storage medium, characterized in that: The non-volatile storage medium includes a stored program, wherein when the program is running, the device where the non-volatile storage medium is located is controlled to execute the address pool management method according to any one of claims 1 to 7.

10. An electronic device, characterized in that: include: A memory and a processor, wherein the processor is used to run a program stored in the memory, wherein the program executes the address pool management method according to any one of claims 1 to 7 when running.
