Mobile terminal and method for quickly searching positioning satellite

Abstract

The invention discloses a mobile terminal and a method for quickly searching a positioning satellite. The mobile terminal comprises a global positioning system (GPS) module, a main control module, a radio interface layer (RIL) module and a memory module, wherein the RIL module is used for acquiring a location area code and a cell identification code; the main control module is used for acquiring information of the positioning satellite in the sky above a base station corresponding to the current cell identification code by using the current location area code and the cell identification code; the memory module is used for storing positioning data of the mobile terminal in the last successive positioning, the location area code and the cell identification code; the main control module is also used for sending the positioning data serving as reference information in the memory module to the GPS module after judging that the location area code and the cell identification code of the memory module is valid; and the GPS module is used for searching the positioning satellite according to the reference information and the information of the positioning satellite in the sky above the base station. The positioning satellite can be quickly searched by the mobile terminal and the method.

Description

technical field [0001] The invention relates to the field of positioning of electronic products, in particular to a mobile terminal and method for rapidly searching and positioning satellites. Background technique [0002] At present, the functions of mobile phones are becoming more and more powerful, and mobile phones with GPS (Global Positioning System) positioning functions have long been used for a long time. However, when using GPS functions, it often takes a long time to obtain location information due to the influence of the environment. Sometimes it may even lead to positioning failure. [0003] When the GPS device is started for positioning for the first time, it generally not only searches for satellites over a specific location, but is in a state of all-round search, so it takes a long time to get the required satellite information, which slows down the speed of GPS positioning . Contents of the invention [0004] The technical problem to be solved by the pres...
