Patent number: 10999716Abstract: 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.Type: GrantFiled: December 31, 2015Date of Patent: May 4, 2021Assignee: Huawei Technologies Co., Ltd.Inventors: Hui Jin, Xiaoguang Wu, Kaiyu Jiang, Liwen Tan

Publication number: 20200280824Abstract: 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.
