Abstract

The present application relates to the field of mobile communication and specifically relates to a mobile terminal and a positioning method therefor. A first valid-location table, a second valid-location table, and an invalid-location table are stored in a terminal. By means of determining in the first valid-location table, the second-valid location table or the invalid-location table location information corresponding to identity information, and transmitting the determined location information to an application that launched a positioning request, rapid positioning of a mobile terminal is implemented. The first valid-location table, the second-valid location table, and the invalid-location table stored in the terminal are amended with more accurate positioning data, thus solving the problem of inaccurate geographic locations being returned by a positioning server.

Description

technical field [0001] The embodiments of the present invention relate to the field of mobile communications, and in particular to a mobile terminal and a positioning method thereof. Background technique [0002] With the rapid development of computer, electronic and communication technologies, various wireless communication services using wireless networks have been provided. Accordingly, services provided by mobile communication systems based on wireless communication networks have evolved from voice services to multimedia services involving transmission of various data such as circuit data and packet data. [0003] Among various wireless Internet services using mobile communication terminals, Location Based Service (LBS) has drawn much attention due to its wide application and convenience. LBS is a communication service that determines the location of mobile communication terminals such as cellular phones and personal digital assistants (PDAs), and provides additional in...
