    Abstract: This application discloses a wireless communication method, apparatus, and system, to ensure service quality of terminal communication in a non-standalone (NSA) networking architecture. The wireless communication method includes starting, by a terminal, radio resource control (RRC) connection establishment with a new radio (NR) cell based on an indication of a network device, and starting a timer based on a quantity of RRC connection establishment failures of the NR cell. The timer is set to a first duration. Within the first duration, when the network device indicates to the terminal to report measurement results of the NR cell and another cell, the terminal only reports the measurement result of the other cell, not the measurement result of the NR cell.

    Abstract: A method for performing a voice control operation on a terminal and an apparatus that relate to the field of audio technologies are provided. The method includes starting an application on the terminal and activating a microphone on the terminal; monitoring a signal status of the activated microphone; and outputting, when the signal status of the microphone transits, a control instruction to change a current operation status of the application. In the present invention, a change of environmental noise picked up by the microphone is used to perform an operation on the terminal application, thereby avoiding interference of the environmental noise in acquiring an audio signal, reducing a key pressing operation of a user, and enhancing user experience.
