Abstract: 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.

Abstract: After a first electronic device establishes a first connection to a second electronic device, a mouse pointer of the first electronic device may cross a boundary of a display interface and appear in a display interface of the second electronic device. When the mouse pointer is displayed on a display of the second electronic device, each time a user performs an input operation by using an input device, such as a mouse or a keyboard, of the first electronic device, the second electronic device may receive an input event from the first electronic device, and make a corresponding response to the input event. At the same time, the input event on the first electronic device side is shielded.
