Abstract

The present invention provides a method for updating positioning data and a mobile terminal. The method includes: acquiring the first location information of the mobile terminal at the current moment and the second location information of the mobile terminal at the previous moment; Information and the second location information, determine the change in the geographic location of the mobile terminal; if the change in the geographic location is greater than a preset value, update the ephemeris data required for positioning and / or the system time of the mobile terminal; The embodiment of the present invention can trigger the mobile terminal to actively update the ephemeris data and / or the system time of the mobile terminal required for positioning when the change in the geographic location of the mobile terminal is greater than a preset value by detecting the change in the geographic location of the mobile terminal. In order to solve the problem that the time and ephemeris data of the mobile terminal are periodically updated, the satellite search time is long or the satellite search fails, and the positioning speed is improved to ensure that the mobile terminal can quickly complete the positioning function at any time.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for updating positioning data and a mobile terminal. Background technique [0002] The existing mobile terminal equipment is equipped with a global positioning system (GNSS), generally one or more of Beidou, Galileo, and GLONASS. The positioning speed of the positioning system depends on the signal strength received by the antenna of the mobile terminal equipment (such as indoor signal very weak, outdoor is very strong), whether the time of the receiver is accurate, and whether it contains the ephemeris information of the current position; It takes a long time. [0003] In the existing positioning scheme, the mobile terminal device needs to complete the satellite search operation according to the current initial position of the mobile phone, the local device time and the stored ephemeris data. After searching for at least 4 satellites, it calculates the user's cu...
