Abstract
Description
Technical Field
[0001] This application relates to the field of communication network technology, specifically to a data acquisition method, apparatus, device, network system, medium, and program product. Background Technology
[0002] In 5G private network deployments, the "shared UPF campus," where the core network is not deployed in a localized area, is a widely adopted model to reduce costs. Under this architecture, terminals and base stations are deployed within the enterprise campus, the User Plane Function (UPF) is typically located at the city / prefecture level, while control plane network elements such as Access and Mobility Management Function (AMF), Session Management Function (SMF), and Unified Data Management (UDM) are concentrated at the provincial level. This distributed architecture reduces hardware deployment and maintenance costs on the enterprise side, but it also presents challenges for the operation and monitoring of the campus network.
[0003] In existing technologies, there are two main approaches to data collection for shared UPF (User-Defined Network) parks. The first relies on the network management systems of each network element. While this method is low-cost, the data is fragmented, with each network element only collecting its own metrics, lacking a holistic view of the end-to-end service link and making it difficult to quickly locate cross-domain faults. The second approach involves widely deploying deep packet inspection (DPI) devices at key nodes in the signaling and user planes (such as interfaces N1, N2, N3, N4, and N6) for traffic collection and analysis. This approach provides comprehensive data but has significant drawbacks: First, multi-point deployment of DPI devices is costly, and with the surge in the number of 5G private network cards, the required storage and processing resources are enormous; second, filtering specific single-card signaling from massive amounts of data is inefficient and does not meet the operational needs of enterprises focusing on specific fault scenarios (such as card offline or overdue payments); finally, traffic mirroring may introduce additional latency to high-load networks.
[0004] Therefore, in view of the above situation, there is an urgent need to provide a data collection networking method based on the 5G private network without the core network being deployed to overcome the shortcomings in current practical applications. Summary of the Invention

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0048] The present application will be further explained below with reference to specific implementation methods.
[0049] The traffic interfaces related to IoT SIM cards mainly include N1 / N2 / N3 / N4 / N6 / N9 / N11 interfaces, among which enterprise customers are more concerned with the usage of private network cards, i.e., the traffic volume of the user plane interface. Therefore, traffic collection needs to be concentrated on the user plane. Currently, the industry commonly adopts the approach of deploying traffic collection equipment between the campus base station and the UPF, such as... Figure 3 As shown;
[0050] This method is an innovative data collection and deployment approach proposed based on the pain points of enterprise customer private network maintenance and the networking of shared UPF private network parks. It simplifies the deployment of DPI to collect data across all data nodes, and deploys only one traffic collection device at the aggregation exit of the city-level data center, following a three-tier architecture of "province-city-enterprise".
[0051] This application provides a data acquisition method applied to an acquisition device, such as... Figure 1 as well as Figures 4 to 6 As shown, the method includes:
[0052] S1. Obtain the transmission data between the first-level network system and at least one User Plane Function (UPF) through the aggregation exit; wherein, the first-level network system is connected to the enterprise network; optionally, the first-level network system is a municipal network;
[0053] S2. Obtain traffic data of the first target node on the enterprise network based on the transmitted data; wherein, the first target node can be a node on the campus DN (enterprise network).
[0054] The data acquisition device can also be called a flow rate acquisition device. For example... Figures 4 to 6 As shown, in the city-level network, the data acquisition device is connected to at least one UPF via a convergence outlet.
[0055] In this embodiment of the application, optionally, the transmitted data includes one or more of the N3 interface data, N4 interface data, N6 interface data, and N9 interface data.
[0056] In this embodiment, the data acquisition device collects the incoming and outgoing traffic on the UPF side using common industry methods, either through traffic mirroring or optical splitting. Optionally, the requirements for the data acquisition device using this embodiment are:
[0057] 1) Sufficient optical ports and resources: The device must ensure that it has enough optical ports and resources to receive mirror traffic from a city;
[0058] 2) Protocol Support: The traffic acquisition device must support the acquisition and parsing of N3 / N4 / N6 / N9 interface protocols;
[0059] 3) Traffic differentiation and filtering: After collecting mirrored traffic, traffic can be differentiated and filtered according to certain rules (such as based on the park DNN), thereby separating the traffic of each shared UPF park in the city.
[0060] The aggregation and export equipment must support traffic mirroring for N3 / N4 / N6 / N9 interfaces and provide sufficient ports as mirroring ports to interface with the traffic acquisition equipment.
[0061] After completing the deployment as described above, the traffic acquisition device can then collect traffic from the N3 / N4 / N6 / N9 interfaces.
[0062] 1) For N4 interface traffic, since the campus 5G private network card or IoT card will attach to the network first, after the attachment is completed, the network-side SMF selects UPF to establish user plane bearer with the campus base station. The relevant signaling will be transmitted between UPF and base station through the aggregation exit, i.e. N4 interface message. This part of the message will be collected by the traffic collection device through traffic mirroring.
[0063] 2) For N3 interface traffic, after the user plane bearer is established, when the enterprise park is carrying out daily park production business, the data transmitted by the terminal device will be sent to the park DN through the base station -> UPF, and the data transmitted by the base station to the shared UPF will be mirrored to the traffic acquisition device when passing through the aggregation exit.
[0064] 3) For N6 interface traffic, after being distinguished by UPF according to certain rules, the services of each park will be sent to the corresponding shared UPF park. When the data passes through the aggregation exit, the traffic collection device can collect it through traffic mirroring.
[0065] 4) For N9 interface traffic, similar to N3 interface traffic, it can be collected through the aggregation exit for roaming scenarios;
[0066] In addition, regarding the online status of 5G private network cards, since the traffic collection device is deployed at the aggregation exit, an enterprise intranet IP can be assigned to the traffic collection device and the route from the device to the park can be established. Based on IP reachability, the traffic collection device periodically initiates ping test requests to each private network card. By detecting the return status and latency of ICMP response packets, the online status of the private network card can be determined in real time.
[0067] Optionally, in this embodiment of the application, the method further includes:
[0068] Send the transmission data and / or the traffic data to the second target node;
[0069] The second target node includes one or more of the following:
[0070] Network nodes in the second-level network system; wherein the second-level network system is connected to the first-level network system and connected to the core network; wherein the second-level network system is a provincial or municipal network;
[0071] Network nodes in the first-level network system;
[0072] Network nodes in the enterprise network.
[0073] Optionally, in this embodiment of the application, step S1, acquiring the transmission data between the first-level network system and at least one user plane function (UPF) through the aggregation exit, includes:
[0074] The transmission data between the first-level network system and the UPF is obtained by using traffic mirroring or optical splitting.
[0075] In this embodiment of the application, optionally, as shown in the example... Figure 5 As shown, the method further includes:
[0076] Obtain the IP address configured in the enterprise network;
[0077] Based on the IP address, a test request is sent to at least one private network card device on the enterprise network through the aggregation exit, the UPF, and the first-level network system.
[0078] The working status of the dedicated network card device is monitored based on its response message to the test request.
[0079] In this embodiment of the application, optionally, monitoring the working status of the dedicated network interface card (NIC) device based on its response message to the test request includes:
[0080] If the response message is detected to meet the first condition, the operating status of the private network card device is determined to be abnormal; the first condition includes one or more of the following:
[0081] No response message was received within the first time period after the test request was sent;
[0082] The time between receiving the response message and sending the test request exceeds a second duration;
[0083] The test request was sent a preset number of times, but no response message was received.
[0084] In this embodiment, if a card fails to respond multiple times consecutively or the latency exceeds a preset threshold, the system will automatically trigger an alarm to notify maintenance personnel to promptly investigate the fault (such as SIM card abnormality, weak base station signal, or UPF forwarding failure). This proactive detection mechanism not only covers offline detection in the silent state of the terminal but also quantifies network transmission quality, such as statistically analyzing average latency, jitter, and packet loss rate, providing data support for network optimization.
[0085] In this embodiment of the application, optionally, as shown in the example... Figure 6 As shown, the method further includes:
[0086] The system obtains a first request message sent by the enterprise network's campus data network (DN) through the aggregation exit and the first-level network system; the first request message is used to request traffic information of the target user; wherein, the first request message includes the IP address of the acquisition device;
[0087] Based on the first request message, the traffic information of the target user is fed back to the campus DN through the aggregation exit and the first-level network system.
[0088] By assigning enterprise intranet IP addresses, customers can also access the traffic acquisition server through the aggregation egress point to view the traffic and 5G private network card online status of the shared UPF park, achieving comprehensive and visualized monitoring of the shared UPF park traffic and 5G private network card online status. Specifically, the traffic acquisition device is assigned an independent enterprise intranet IP address, and a routing policy establishes a connection channel with the park's internal network. After accessing the aggregation egress point via VPN or dedicated line, customers can directly access the web management platform deployed on the traffic acquisition device. This platform provides a real-time dashboard, presenting key indicators such as overall network traffic distribution, peak service trends, private network card online rate, and end-to-end latency in dynamic chart format, opening a private network operation and maintenance window for park customers.
[0089] One embodiment of this application also provides a data acquisition device, applied to acquisition equipment. Please refer to [link / reference]. Figure 2 The device includes:
[0090] The first acquisition module 100 is used to acquire the transmission data between the first-level network system and at least one User Plane Function (UPF) through the aggregation exit; wherein the first-level network system is connected to the enterprise network, and the transmission data includes one or more of N3 interface data, N4 interface data, N6 interface data and N9 interface data;
[0091] The second acquisition module 200 is used to obtain traffic data of the first target node on the enterprise network based on the transmitted data.

[0096] Network nodes in the enterprise network.

[0098] The transmission data between the first-level network system and the UPF is obtained by using traffic mirroring or optical splitting.
[0099] Optionally, the data acquisition device further includes a third acquisition module 400, used to acquire the IP address configured in the enterprise network; send a test request to at least one private network card device on the enterprise network through the aggregation exit, the UPF and the first-level network system based on the IP address; and monitor the working status of the private network card device based on the response message of the private network card device to the test request.
[0100] Optionally, in the data acquisition device, the third acquisition module 400 monitors the working status of the dedicated network card device based on the response message of the dedicated network card device to the test request, including:
[0101] If the response message is detected to meet the first condition, the operating status of the private network card device is determined to be abnormal; the first condition includes one or more of the following:
[0102] No response message was received within the first time period after the test request was sent;
[0103] The time between receiving the response message and sending the test request exceeds a second duration;
[0104] The test request was sent a preset number of times, but no response message was received.
[0105] Optionally, the data acquisition device further includes a fourth acquisition module 500, used to acquire a first request message sent by the enterprise network's campus data network DN through the aggregation exit and the first-level network system; the first request message is used to request traffic information of the target user; wherein, the first request message includes the IP address of the acquisition device;
[0106] Based on the first request message, the traffic information of the target user is fed back to the campus DN through the aggregation exit and the first-level network system.
[0107] In this embodiment, the method described in this application focuses on shared UPF parks, proposing a method for collecting traffic and terminal data, and providing shared park customers with a way to log in remotely, which is conducive to commercial monetization. The key points of the solution are as follows:
[0108] 1) Traffic acquisition deployment location: Deploy traffic acquisition equipment at the aggregation outlet to complete N3 / N4 / N6 / N9 traffic mirroring acquisition through traffic mirroring or optical splitting;
[0109] 2) IoT SIM card monitoring: A traffic acquisition device is connected next to the aggregation exit. By assigning a private network IP address to the enterprise campus and establishing a route from the IP address to the enterprise private network, the 5G private network card can be monitored and tested from the traffic acquisition device.
[0110] 3) Remote login for customers in the shared UPF park: Since the traffic acquisition device has been assigned an internal enterprise IP address, by establishing a route from this IP address to the internal enterprise network, customers can remotely access the traffic acquisition device via a VPN dedicated line to achieve real-time perception of the network quality of this shared UPF park.
[0111] One embodiment of this application also provides a data acquisition device, including: a processor, a memory, and a program or instructions stored in the memory and executable on the processor; when the processor executes the program or instructions, it implements the data acquisition method described above.

[0113] The specific implementation structure of the network system can be as follows: Figures 4 to 6 As shown, it will not be explained in detail here.

[0115] One embodiment of this application also provides a computer program product, including computer instructions, which, when executed by a processor, implement the steps in the data acquisition method described above.
[0116] The commercial value of this application lies in:
[0117] In terms of 5G private network construction, due to construction costs, the number of shared UPF parks far exceeds the number of decentralized UPF parks. According to China Mobile's statistics in December 2024, there were approximately 6,000 5G private network parks nationwide, while the number of decentralized parks was approximately 1,000, a ratio of roughly 6:1.
[0118] This situation directly reflects the practical considerations of operators and enterprises: while decentralized UPF parks offer advantages in localized data management, each park requires independent deployment of core network elements (such as UPF and SMF), with hardware procurement costs exceeding 2 million yuan and annual maintenance costs of approximately 500,000 yuan; while shared UPF parks, by reusing provincial core network resources, can reduce construction costs by 60%-70%, making them particularly suitable for small and medium-sized enterprise customers. However, behind this cost advantage lies a severe monitoring dilemma—currently, over 90% of network monitoring solutions focus on decentralized parks, leaving shared parks in a long-term "monitoring blind spot." Enterprise customers cannot grasp key indicators such as wireless signal quality (e.g., RSRP / SINR) and user plane latency (N3 / N6 interface) in real time, nor can they locate cross-domain transmission faults (e.g., routing anomalies between the provincial core network and the municipal UPF), severely restricting the reliability verification of 5G private networks in industrial production.
[0119] From the operator's perspective, the 6,000 shared UPF parks nationwide constitute a blue ocean market for monitoring services worth over 10 billion yuan. Assuming a basic monitoring service fee of 50,000 yuan per park per year, the basic functions alone can generate 300 million yuan in annual revenue. If customized functional modules (such as AI fault prediction and business SLA assurance) are added, the overall market potential could exceed 500 million yuan.
[0120] Meanwhile, the operator's investment cost is relatively low; investing in one set of traffic collection equipment in one city can be reused by all shared UPF parks within that city. If subsequently rolled out nationwide, the total cost is expected to be no more than 100 million yuan, with a projected total profit of 80%.
[0121] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
