Description

Technical Field

[0001] This invention relates to the field of communications, and in particular to a signaling tracing method and apparatus based on a Qualcomm 5G module. Background Technology

[0002] 5G is currently experiencing rapid promotion and widespread application in China. Since the commercialization of 5G, China has been committed to building the world's largest and most advanced 5G network. Major operators are actively deploying 5G base stations, continuously expanding coverage, and enabling both urban and rural areas to enjoy high-speed, stable network connections. The rapid promotion of 5G technology has brought unprecedented opportunities for digital transformation and innovation, involving various industries, including smart manufacturing, autonomous driving, telemedicine, and virtual reality. People can experience faster download speeds, lower latency, and greater network capacity, providing powerful support for smart devices, the Internet of Things, and cloud computing. China's 5G development has not only driven the rapid development of the digital economy but also brought more convenience and possibilities to people's lives, work, and entertainment.

[0003] 5G signaling plays a crucial role in resolving 5G network issues. The following are some aspects of how 5G signaling addresses these issues:

[0004] Connectivity Management: 5G signaling is used to establish and maintain connections between devices and the network. It assists devices in authenticating with the network, negotiating keys, and establishing secure connections. Through signaling, the network can manage the connections of multiple devices, ensuring that devices can correctly connect to the network and provide high-quality services.

[0005] Bandwidth Management: 5G signaling facilitates effective management of network bandwidth. It can dynamically allocate and manage bandwidth resources based on network and device needs. Through signaling, the network can intelligently adjust according to real-time traffic demands, ensuring that each device receives appropriate bandwidth and achieving optimal utilization of network resources.

[0006] Troubleshooting: 5G signaling plays a crucial role in troubleshooting. It can be used to identify and locate problems in the network, including device connectivity issues and network congestion. Through signaling, the network can collect status information about devices and the network itself, and analyze and resolve problems to improve network reliability and performance.

[0007] Mobility Management: 5G signaling can effectively manage device mobility. It can track changes in device location and automatically switch to the optimal network connection point when the device moves. Through signaling, the network can provide seamless mobility management, ensuring that devices maintain a stable connection and provide continuous network services while on the move.

[0008] QoS (Quality of Service) Management: 5G signaling is used to manage and ensure the quality of service in the network. It can monitor and control metrics such as latency, throughput, and reliability in the network. Through signaling, the network can optimize resource allocation, adjust transmission parameters, and provide the appropriate QoS levels required by different applications and services.

[0009] In summary, 5G signaling plays a crucial role in resolving 5G network issues. While 5G CEP (Customer Electronic Equipment) is widely used in enterprises, troubleshooting problems can be challenging. 5G signaling can significantly shorten fault location and troubleshooting time, meeting customer needs and improving customer satisfaction.

[0010] 5G technology standards are constantly evolving, and different standards and technologies may exist between different regions and manufacturers. This can lead to compatibility issues between devices, affecting interoperability and the integration of industrial systems. Therefore, monitoring the normal operation of 5G CPEs during deployment and use becomes a crucial part of ensuring network security for production and daily life. Although 5G features high speed and low latency, its advantages cannot be fully realized in all industrial applications. Some applications may have lower requirements for network bandwidth and latency, but rather prioritize stability and reliability.

[0011] Currently, there are two main methods for capturing 5G signaling from a CPE. One method involves using specialized software on a computer to connect to the CPE and capture signaling. This method requires manual on-site visits to the enterprise. However, CPEs are installed in various locations, such as inside machines, vehicles, or underground mines, making it difficult for personnel to reach the site in case of problems. The other method uses built-in signaling tools. However, these tools do not support capturing signaling by type, and the captured signaling data is extremely large, reaching hundreds of megabytes per minute on a CPE. Since CPEs have a router-like structure, their internal storage is generally small, making it difficult to capture signaling for extended periods in case of problems, which is not conducive to fault location and long-term monitoring.

[0012] Therefore, in practical use, it is necessary to carefully evaluate and match the application scenarios of 5G technology. Thus, a method is needed to monitor and maintain CPE. Through signaling layer analysis, customers can quickly locate faults when using 5G. Summary of the Invention
