Abstract: Various embodiments relate to the field of communications technologies, and provide a light adjustment method and a terminal to resolve a problem that an existing light therapy device cannot flexibly adjust light based on a light requirement of a user and cannot more intelligently adjust a circadian rhythm of the user. In those embodiments, an awake time period and a sleep time period of a user is determined by the terminal, and parameter thresholds in the awake time period and the sleep time period is determined by the terminal. In those embodiments, a light parameter in a current time period is obtain by the terminal, and based on the light parameter in the current time period, a light parameter of light emitted by a light source device is then adjusted by the terminal.

Abstract: 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.

Abstract: 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.

Abstract: 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.
