Optimized method, system, and storage medium for application to retrieve ue identifier

This invention discloses an optimized method, system, and storage medium for retrieving UE identifiers by an application. When the DCAF needs to obtain a UE identifier, the UDM simultaneously receives a first authentication request from the NEF (including an analysis ID and a first IP address) and a second authentication request from the AMF (including a subscription hidden identifier and a second IP address). Upon verifying that the first IP address and the second IP address are identical, the UDM converts the subscription hidden identifier into a subscription permanent identifier. After confirming successful UE authentication based on the subscription permanent identifier, the UDM returns authentication response information including the subscription permanent identifier and the analysis ID to the NEF. This allows the NEF to generate an external UE identifier in a preset format based on the subscription permanent identifier and send the external UE identifier to the DCAF. This invention improves response speed and reduces latency by sending requests to different network elements of the 5G core network.

A PWM-based high-speed switching valve hysteresis compensation control method

This invention proposes a hysteresis compensation control method for high-speed switching valves based on PWM, belonging to the field of high-speed switching valve control. Its key feature is that the working cycle of the high-speed switching valve is divided into four stages. The rising and falling edges of the reference PWM control the opening and closing times of the high-speed switching valve, while the loading signal consists of on-compensation PWM, excitation PWM, opening-hold PWM, and closing compensation PWM. By varying the pressure before the valve, the critical voltage values ​​for opening and closing the valve core are obtained, thereby controlling the amplitudes of the on-compensation PWM and opening-hold PWM to reduce the hysteresis time and current consumption of the valve core response. The duty cycle of the excitation PWM is determined by the derivative of the pressure before the valve, and the duty cycles of the on-compensation PWM and closing compensation PWM are obtained based on the coil current, accelerating the valve core response speed and optimizing current consumption. This invention can improve the response speed of high-speed switching valves, reduce energy consumption, and expand the frequency response range, offering advantages such as high response, low power consumption, low cost, and small footprint.
