Publication number: 20230412295Abstract: Embodiments of this application provide a method and an apparatus for service processing in a terminal device. The terminal device is provided with a first card and a second card. When the terminal device is using the second card for performing a voice service, if the terminal device receives a data service request that requires the first card for implementation, the terminal device may search for a cell corresponding to a first band. The cell corresponding to the first band is a cell accessed by the first card before the first card enters an idle state. Therefore, when the terminal device has found the cell corresponding to the first band, the voice service of the terminal device is not interrupted. The terminal device can implement both the data service of the first card and the voice service of the second card, allowing more usage scenarios for the terminal device.Type: ApplicationFiled: May 9, 2022Publication date: December 21, 2023Applicant: Honor Device Co., Ltd.Inventors: Yun WANG, Dezhi WANG
