Abstract

The invention provides a location method and system and a mobile terminal. The location method comprises the following steps that: a mobile terminal initiates an SUPL (secure user plane location) flow and a Wifi (wireless fidelity) location flow; and the location result of the mobile terminal is determined based on the SUPL location result and the Wifi location result. According to the invention, the location success rate is effectively improved, and the location precision is enhanced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a positioning method and system based on WIFI positioning and SUPL positioning, and a mobile terminal. Background technique [0002] Mobile positioning service means that the mobile network obtains the location information (latitude and longitude coordinates) of the mobile terminal through a specific positioning technology, provides it to the user himself, the communication system or a third party, and provides the mobile user with the support of certain electronic map information. A value-added service related to information. The application of mobile positioning service is very wide. It can make mobile users more convenient when going out and help us reach the destination in the most economical way; it can also allow us to get faster rescue in case of emergency; it can also help us get The location of loved ones and so on. More and more mobile positioning services requ...
