[0045] 5G, characterized by high speed, low latency, and large capacity, is currently being rapidly deployed and applied both domestically and internationally. While 5G is playing an increasingly important role, its maturity still requires time to gradually improve. For example, in the early stages of 5G development, numerous terminal and network compatibility issues will arise, involving positioning air interface anomalies. These anomalies include problems with the terminal itself, network coverage, and network equipment.
[0046] Because the underlying air interface logs are enormous and the storage space of the communication module is limited, the current methods for monitoring and repairing air interface anomalies provided by the terminal cannot achieve offline storage and rapid location of air interface anomalies. When encountering field problems, they can only be captured in real time, and for probabilistic problems, they can only be reproduced on-site. This results in low efficiency in locating air interface anomalies, which is time-consuming, manpower-intensive, and affects user experience.
[0047] To address the aforementioned technical problems, this embodiment provides an air interface anomaly handling method applicable to terminal devices. By creating a new storage partition in the CP module and cyclically storing the air interface logs generated by the terminal device in this partition, when the AP module detects an air interface anomaly, it can retrieve the current air interface logs of the terminal device from this storage partition, thereby effectively improving the efficiency of locating air interface anomaly problems. A detailed embodiment is provided below for further explanation.
[0048] Among them, reference Figure 1 , Figure 1 This is a schematic diagram of the architecture of a terminal device provided in an embodiment of this application. In this embodiment, the terminal device includes a communication module and a processing module 20 (also known as a host computer); wherein the communication module includes an AP module 101 and a CP module 102.
[0049] In some embodiments, the AP module provides internet access and other services, while the CP module (Modem) handles wireless communication to enable communication with other devices on the network. Communication between the AP module and the CP module is internal processor communication. For example, the AP module sends different control commands to the CP module under different service scenarios, or the AP module and CP module communicate by transmitting uplink and downlink Internet Protocol (IP) packets to complete internet access services.

[0051] S201. Create a new first storage partition in the CP module, and store the air interface logs generated by the terminal device in a loop in the first storage partition.
[0052] In this embodiment of the application, when it is necessary to perform air interface anomaly testing on the terminal device, a first storage partition is created in the CP module, and the air interface logs generated by the terminal device are stored in the first storage partition in a loop.
[0053] In one feasible implementation, the aforementioned first storage partition can be created in the memory of the CP module.
[0054] Optionally, the first storage partition mentioned above may store at least a few minutes of air interface logs.
[0055] The aforementioned first storage partition has a circular storage function for air interface logs. Air interface logs exceeding the capacity of the first storage partition will be overwritten by the earliest stored air interface logs in a circular manner.
[0056] S202. Use the AP module to monitor whether there are any abnormalities in the air interface of the terminal equipment.
[0057] In one feasible implementation, the AP module can be used to monitor whether the air interface of the terminal device meets the preset abnormality triggering conditions. When the air interface of the terminal device meets the preset abnormality triggering conditions, it is determined that there is an abnormality in the air interface.
[0058] Optionally, the above-mentioned abnormal triggering conditions include the terminal initiating reconstruction, the uplink and downlink rates being lower than the threshold within the time window, and the uplink PDCP first packet delay being greater than the threshold, etc., which are not limited in this embodiment.

The operation and maintenance device can then locate and analyze the air interface anomaly based on the air interface log.
[0061] The air interface anomaly handling method provided in this embodiment creates a new storage partition in the CP module and stores the air interface logs generated by the terminal device in the storage partition in a loop. When the AP module detects an anomaly in the air interface, it can obtain the current air interface logs of the terminal device from the storage partition, thereby effectively improving the efficiency of locating air interface anomaly problems.
[0062] Based on the content described in the above embodiments, a second storage partition can also be created in the AP module; when there is an anomaly in the air interface, the air interface log currently stored in the first storage partition is transferred to the second storage partition.
[0063] The processing module can also obtain air interface logs from the aforementioned second storage partition.
[0064] In one feasible implementation, the aforementioned second storage partition can be created in the Flash memory of the AP module.
[0065] In one feasible implementation, when using the AP module to monitor whether there is an anomaly in the air interface of the terminal device, the AP module can be used to monitor whether the air interface of the terminal device meets the preset anomaly triggering conditions; when the air interface of the terminal device meets the preset anomaly triggering conditions, it is determined that there is an anomaly in the air interface.
[0066] In some embodiments, when the air interface of the terminal device meets the preset abnormal triggering conditions, the AP module determines the abnormal event existing in the air interface based on the abnormal triggering conditions currently met by the air interface of the terminal device and the pre-set correspondence between the abnormal triggering conditions and the abnormal event, and sends it to the processing module.
[0067] In some embodiments, refer to Table 1, which is a table showing the correspondence between abnormal triggering conditions and abnormal events.
