Publication number: 20240040653Abstract: This application provides a secondary cell group configuration method and apparatus. The method includes: receiving an LTE RRC reconfiguration message, where the LTE RRC reconfiguration message includes an NR configuration parameter, and the NR configuration parameter is used to configure an SCG; sending indication information when a terminal device does not support a configuration of the SCG, where the indication information is used to indicate that the SCG is abnormal. After receiving the indication information, if the network device determines that the terminal device needs to release the SCG, the network device may indicate the terminal device to release the SCG.Type: ApplicationFiled: September 16, 2021Publication date: February 1, 2024Inventors: Bei Dai, Xianzhuan Hu, Xianting Qi, Hao Zhang

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

Patent number: 9924484Abstract: A network registration method and apparatus, and a mobile terminal are presented. During re-registration with a network, after receiving a channel allocation rejection message sent by the network, a mobile terminal sorts all available frequency channels according to network resource statuses of frequency channels with which network registration failed before and that are in a low priority list. And then the mobile terminal tries to camp on all the available frequency channels according to an order of the sorting to determine a frequency channel to be camped on. The mobile terminal sends a network registration message to register with the frequency channel to be camped on.Type: GrantFiled: May 20, 2014Date of Patent: March 20, 2018Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Bei Dai, Xiaojian Liu, Li Shen, Yinqing Jiang
