Abstract

The invention provides an intelligent terminal positioning method and system and relates to the technical field of mobile positioning. The intelligent terminal positioning method comprises the steps that the accelerated speeds of an intelligent terminal at different times are acquired, and a curve of the relation between the accelerated speeds and the times is generated; the motion state and the displacement of the intelligent terminal are obtained according to the curve of the relation between the accelerated speeds and the times; a positioning mode is selected according to the motion state and the displacement of the intelligent terminal, and positioning is conducted in the selected positioning mode, wherein positioning modes include the base station positioning mode, the intelligent positioning mode and the GPS positioning mode. According to the intelligent terminal positioning method and system, the three positioning modes are set, the positioning modes can be switched automatically by the intelligent terminal according to the motion state and the displacement of the intelligent terminal, positioning power consumption is reduced on the premise that the positioning precision is guaranteed, and the requirements of people for positioning precision and positioning power consumption are met.

Description

technical field [0001] The invention belongs to the technical field of mobile positioning, and in particular relates to a positioning method and system for an intelligent terminal. Background technique [0002] In recent years, location-based services have become an important service index of smart terminals, which provide great convenience for people's daily life location-based services, and also promote the vigorous development of location-based services. [0003] At present, there are two types of positioning technologies provided on smart terminals, one is base station positioning based on the mobile operating network, and the other is positioning based on GPS. Our test experiments on smart terminals show that the base station positioning based on the mobile operation network consumes less energy, but the accuracy is poor, and it is difficult to provide accurate street levels in urban environments with complex streets and buildings; GPS-based Positioning can provide hig...
