Abstract: This application provides an outdoor device unit reset system, to resolve a problem in a conventional technology that an outdoor device unit needs to be reset by using a reset switch on the outdoor device unit. The system includes a voltage regulation apparatus connected to a power supply apparatus and an outdoor device unit connected to the voltage regulation apparatus. The voltage regulation apparatus is configured to regulate, based on a detected feedback signal, a supply voltage provided by the power supply apparatus for the voltage regulation apparatus, and a reference voltage of the voltage regulation apparatus, a working voltage input to the outdoor device unit. The outdoor device unit is configured to: determine a change amount of the working voltage input to the outdoor device unit, and perform a reset operation when the change amount is within a preset range.

Abstract: A high-speed data transmission degradation method, a device, and a system, to implement, in high-speed data transmission and depending on a terminal requirement, resource degradation in which interaction load is low and a terminal remains connected to a network, so as to ensure a data transmission rate of the terminal and improve terminal user experience. The method includes receiving, by a network-side device, a degradation request sent by a terminal that is in a high-speed data transmission mode; obtaining, by the network-side device, a target to-be-degraded resource of the terminal based on the received degradation request; and degrading, by the network-side device, the target to-be-degraded resource.
