Patent number: 11209555Abstract: A positioning method and apparatus for a mobile terminal, and a mobile terminal. After a first time period elapses, a main processor obtains M pieces of reliable navigation data from N pieces of buffered navigation data of the mobile terminal, and obtains K pieces of buffered position change data of the mobile terminal. The main processor combines the M pieces of reliable navigation data and the K pieces of position change data, to obtain position information of the mobile terminal in the first time period. The N pieces of navigation data are obtained through calculation by using a satellite navigation signal of the mobile terminal that is received during the first time period. The K pieces of position change data are obtained through calculation by using data that is obtained through monitoring by a sensor of the mobile terminal during the first time period.Type: GrantFiled: November 10, 2015Date of Patent: December 28, 2021Assignee: Huawei Technologies Co., Ltd.Inventors: Chenxi Lu, Yuanfeng Chen, Li Kang

Patent number: 10900789Abstract: A positioning method and a mobile device, where the method is applied to the mobile device and includes periodically detecting a status of the mobile device, where the status of the mobile device includes a driving state and a walking state, positioning the mobile device using a first positioning algorithm when detecting that a quantity of times that the driving state consecutively occurs reaches M, where the M is an integer greater than one, and positioning the mobile device using a second positioning algorithm when detecting that a quantity of times that the walking state consecutively occurs reaches N, where the N is an integer greater than one. Hence, the status of the mobile device can be more accurately determined by implementing this technical solution to position the mobile device using a positioning algorithm matching an actual status of the mobile device, thereby improving accuracy of a positioning result.Type: GrantFiled: May 20, 2016Date of Patent: January 26, 2021Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Chenxi Lu, Yu Wang, Guoliang Li, Xiaohan Chen

Patent number: 10539677Abstract: A method includes: obtaining an azimuth and a signal parameter value of each preset satellite of M preset satellites when a mobile terminal is at a first location. The M preset satellites are sorted according to the values of their azimuths and N satellite combinations are obtained from those satellites that are consecutively arranged and have signal parameter values less than preset values. In response to determining that a ratio of the quantity of the preset satellites in the first satellite combination to M is less than a first threshold, the positioning mode of the mobile terminal is set to an outdoor positioning mode. In response to determining that a ratio of the quantity of the preset satellites in the first satellite combination to M is greater than a second threshold, the positioning mode is set to an indoor positioning mode.Type: GrantFiled: June 4, 2015Date of Patent: January 21, 2020Assignee: Huawei Technologies Co., Ltd.Inventors: Chenxi Lu, Shuiping Long
