  • Publication number: 20210243573
    Abstract: This disclosure relates to a call prompt method and terminal. In one aspect, the method includes displaying a first interface on a display screen of a first terminal, showing that a first terminal is in a call with a second terminal via the CDMA communication network; while the first terminal is in the call with the second terminal, displaying a second interface on the display screen that prompts that a third terminal is initiating a call to the first terminal; outputting a sound that includes a prompt tone and a call voice between the first terminal and the second terminal, the prompt tone is used to prompt a call event indicating that the third terminal is initiating a call to the first terminal; and when the call initiated by the third terminal is rejected by the first terminal's user, continuing output of the call voice between the first terminal and the second terminal, and stopping output of the prompt tone.

  • Patent number: 10999716
    Abstract: Methods, systems, and apparatus for call prompting when a call initiated by a terminal is unconnected during a call between two other terminals. In one example method, a first interface, indicating that the first terminal is in a call with a second terminal, is displayed on the first terminal. If a third terminal initiates a call to the first terminal, a second interface, indicating the call initiated by the third terminal, is displayed on the first terminal, and a sound, which includes a call voice and a prompt tone of the initiated call, is output. If the third terminal's initiated call is rejected, the call voice is output on the first terminal, and the prompt tone stops being output. If the third terminal stops initiating the call, the first interface is displayed on the first terminal, and the call voice between the first terminal and the terminal continues being output.

  • Publication number: 20200280824
    Abstract: The present disclosure relates to a call prompt method. In one example method, a first interface, indicating that the first terminal is in a call with a second terminal, is displayed on a first terminal. If a third terminal initiates a call to the first terminal at this moment, a second interface, indicating the call initiated by the third terminal, is displayed on the first terminal, and a sound is output. The sound includes a call voice and a prompt tone of the initiated call. If the call initiated by the third terminal to the first terminal is rejected, the call voice is output on the first terminal, and the prompt tone stops to be output. Or if the third terminal stops initiating the call, the first interface is displayed on the first terminal, and the call voice between the first terminal and the terminal continues to be output.
