Abstract: A pedal fault diagnosis method and apparatus for a vehicle are provided, including: detecting whether a driver seat is in an unmanned state; collecting an actual zero position voltage of a pedal when the driver seat is in the unmanned state; and then determining, based on the actual zero position voltage, whether a zero position fault exists on the pedal. The apparatus may update a set value of a zero position voltage in a vehicle controller based on the actual zero position voltage that is collected when the driver seat is in the unmanned state, and may be applied to the fields of assisted driving and automatic driving. Vehicle control safety can be improved by using the actual zero position voltage that is collected when the driver seat is in the unmanned state.

Abstract: A centralized controller determines n radio remote units (RRUs) in m RRUs, where a sum of first downlink reference signal received powers (RSRPs) of a same terminal, corresponding to the n RRUs, is greater than or equal to a first preset value, and a first downlink RSRP of one terminal corresponding to one is a received power that is estimated by the centralized controller, that is measured by the terminal, and that is of a reference signal (RS) from the RRU at a corresponding first RS transmit power. The centralized controller turns off an RRU that is in the m RRUs and that is different from the n RRUs, boosts a second RS transmit power corresponding to each of the n RRUs to a corresponding first RS transmit power, and enables each of the n RRUs to send an RS at the corresponding first RS transmit power.

Abstract: This application discloses a container access method and apparatus. The method includes: receiving a container access request, which is used to request to access a target container; selecting a driver instance corresponding to the target container from multiple currently-running driver instances, where different driver instances in the multiple driver instances are used to drive different types of containers, and the multiple driver instances are managed by using a same program; and sending the container access request to the selected driver instance. In this solution, one program manages driver instances that are used to drive different types of containers, so that a user can access multiple containers of different types by using one program. This reduces running overheads of a program that manages multiple driver instances in a container engine.

Abstract: Embodiments of the present disclosure provide a communications method, device, and terminal. The method includes: determining that a micro network cooperated with a macro network is in a channel tailor mode, wherein some common physical channels except a pilot channel of the micro network are in a disabled state so that the micro network is disabled from supporting initial access of a terminal; monitoring whether a terminal on a macro network has a service requirement on the micro network; and sending a network handover instruction that comprises configuration information of the micro network to the terminal if the terminal has a service requirement on the micro network, wherein the network handover instruction is used to instruct the terminal to hand over from the macro network to the micro network.

Abstract: The application discloses a method and a system for information synchronization between cloud storage gateways and a cloud storage gateway, to resolve a problem that an address obtained by a cloud storage gateway is usually a dynamic address or even a private address, and it is difficult to perform direct communication and impossible to perform directory synchronization. A cloud storage gateway obtains, from a cloud message queue of a cloud service provider, a directory distributed by another cloud storage gateway; and therefore, as long as the cloud storage gateway can communicate with the cloud service provider, directory synchronization can be implemented without a need of direct communication between the cloud storage gateways. Therefore, even through an address obtained by the cloud storage gateway is a dynamic address or a private address, directory synchronization is not affected.
