Patent number: 11412434Abstract: A cell selection method includes: when a terminal camps on a first network that does not support a voice service, and voice service needs to be initiated or received, falling back, by the terminal in a circuit switched fallback (CSFB) manner, to a second network that supports the voice service when the terminal fails to establish the voice service with the second network, saving, by the terminal, a location identifier of the first network and a location identifier of the second network to a blacklist. The blacklist is used by the terminal to choose to camp on a cell of the second network when performing CSFB subsequently.Type: GrantFiled: November 24, 2017Date of Patent: August 9, 2022Assignee: HUAWEI TECHNOLGOIES CO., LTD.Inventors: Zhongjin Li, Wenjie Duan, Shuiping Long, Qiang Yi, Guochao Xiong, Liang Hua, Fudong Pang, Sicong Yang

Patent number: 11246061Abstract: The present invention provides a voice service processing method and a terminal device. The method includes: sending, by a terminal device, a first message to a network device of a first network, where the first message is used to request a circuit switched fallback CSFB voice service; receiving, by the terminal device, a second message sent by the network device of the first network, where the second message is used to instruct the terminal device to perform network redirection; if the second message carries no frequency information, determining, by the terminal device, a redirection frequency, where the redirection frequency is a frequency supported by a second network; and sending, by the terminal device based on the redirection frequency, a connection request to a network device of the second network, to perform a CS voice service.Type: GrantFiled: March 30, 2016Date of Patent: February 8, 2022Assignee: HONOR DEVICE CO., LTD.Inventors: Zhongjin Li, Wenjie Duan, Zhichao Chen

Patent number: 10841968Abstract: Embodiments of the present invention provide a call prompt method. A first interface that shows that a 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 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, where 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. Additionally or alternatively, 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.Type: GrantFiled: July 18, 2016Date of Patent: November 17, 2020Assignee: Huawei Technologies Co., Ltd.Inventors: Zhongjin Li, Wenjie Duan, Zhichao Chen
