Patent number: 11412443Abstract: Embodiments provide a method for searching for a network by a terminal, a terminal, and a storage medium, which reduce network search time. A terminal controls a first wireless communications module to search a first band for a first camping frequency channel number and controls a second wireless communications module to search a second band for a second camping frequency channel number. Therefore, compared with the prior art in which both the first wireless communications module and the second wireless communications module search a full band for a network, the embodiments can accelerate a network search process of the terminal. If the first wireless communications module finds a to-be-camped-on frequency channel number that meets a preset condition, the terminal shares the to-be-camped-on frequency channel number found by the first wireless communications module with the second wireless communications module, thus shortening a network search time of the second wireless communications module.Type: GrantFiled: July 28, 2018Date of Patent: August 9, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Yinqing Jiang, Xiaojian Liu, Bei Dai
