摘要： A camera compact module installation method and a mobile platform are provided, and are used for autonomous driving or intelligent driving. The method includes: installing a camera compact module on a mobile platform, where the camera compact module is parallel to a ground on which the mobile platform is located. The camera compact module includes a lens group and an image sensor, and the lens group includes at least one lens. A projection of a center of the lens group on a plane of the image sensor is a first position. A distance between the first position and a center of the image sensor is greater than a first threshold, and the first threshold is greater than 0. In this way, because the camera compact module can be parallel to the ground on which the mobile platform is located, it can be ensured that a motion direction is perpendicular to the plane of the image sensor. This can improve accuracy and robustness of camera motion estimation, to reduce a target positioning error. In addition, a required detection range can be met without tilting the camera compact module for installation. The method may be applied to the internet of vehicles, for example, vehicle-to-everything V2X, long term evolution-vehicle LTE-V, or vehicle-to-vehicle V2V.

摘要： This application discloses a network and a data transmission method and apparatus, and belongs to the field of communication technologies. The network includes a core device and an edge device. The edge device identifies a service type of a first service packet from the core device, and reports a service type identifier of the first packet to the core device. The core device determines a priority corresponding to the service type identifier based on a stored service priority correspondence, and forwards, based on the priority, a service packet belonging to a same service flow as the first service packet. A strong service identification capability of the edge device is used to precisely identify thousands of service types, and a strong entry storage capability of the core device is used to store a correspondence that records thousands of service types and priorities. This effectively avoids problems such as transmission congestion and a packet loss that are caused by an incapability of precisely identifying a service type and allocation of a same priority to service packets of different service types.

摘要： Embodiments of this application relate to the field of wireless communications technologies, and provide an access method, a switch method, and an apparatus. The access method includes: receiving, by a terminal, a system message via a downlink carrier, where the system message includes information used to indicate a frequency channel number of a second uplink carrier; and initiating, by the terminal, random access via the second uplink carrier; where a frequency channel number of the downlink carrier belongs to a first frequency band, and a frequency channel number of the second uplink carrier belongs to a second frequency band. In this method, when the terminal A is accessed to a base station, an uplink frequency band and a downlink frequency band of the terminal A may be different, so that appropriate frequency band resources may be selected, based on an actual network status, for uplink transmission and downlink transmission, thereby effectively utilizing the radio resources.
