Embodiment 1

[0043] Please refer to figure 1 , is the method for obtaining the location information of the mobile terminal in this embodiment, including:

[0044] Step 101: Turn on the satellite positioning module of the mobile terminal, close it after obtaining the current location information of the mobile terminal, and use the current location information as the initial location information;

[0045] Step 102: The sensing module of the mobile terminal collects motion information of the mobile terminal, and calculates the displacement variation of the mobile terminal according to the motion information;

[0046] Step 103: Obtain the actual location information of the mobile terminal according to the initial location information and the displacement variation of the mobile terminal.

[0047] The method of this embodiment may further include: periodically turning on the satellite positioning module of the mobile terminal to acquire the current location information of the mobile terminal, ...

Embodiment 2

[0079] Based on the method for acquiring location information of a mobile terminal in Embodiment 1, this implementation takes a mobile phone with a GPS or AGPS module as an example. The basic idea is: take the device position read by the GPS (AGPS) module as the origin, use the acceleration sensor and electronic compass to measure the device acceleration, calculate the device displacement increment, thereby calculate the actual position of the device at the corresponding time, and update the device position in time information; the GPS (AGPS) module reads the position information again, updates the initial position of the device (that is, the origin of the last displacement), sets the displacement increment to 0, recalculates the displacement increment, and cycles in this way; the GPS ( The specific time threshold or displacement threshold of the position information read by the AGPS) module makes the reading frequency lower, such as reading once per minute, so that the GPS (AG...

Abstract

The invention discloses a mobile terminal and a method for obtaining the position information of the mobile terminal. The method for obtaining the position information of the mobile terminal comprises the following steps that a satellite positioning module of the mobile terminal is turned on and then turned off after the current position information of the mobile terminal is obtained, and the current position information is used as initial position information; the movement information of the mobile terminal is collected by a sensor module of the mobile terminal, and the displacement variation of the mobile terminal is calculated in accordance with the movement information; and the actual position information of the mobile terminal is obtained in accordance with the initial position information and the displacement variation of the mobile terminal. By using the mobile terminal and the method for obtaining the position information of the mobile terminal, the power consumption of the satellite positioning module can be reduced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a mobile terminal and a method for acquiring position information of the mobile terminal. Background technique [0002] Due to the all-weather, high-precision and automatic measurement characteristics of GPS (Global Positioning System) technology, as an advanced measurement method and new productivity, it has been integrated into various application fields of national economic construction, national defense construction and social development. [0003] With the end of the Cold War and the vigorous development of the global economy, the US government announced that from 2000 to 2006, under the premise of ensuring that the national security of the United States would not be threatened, the SA policy would be abolished, and the accuracy of GPS civilian signals would be improved globally. The single-point positioning accuracy of / A code is increased from 100 meters to 10 meters,...
