Method and system for capturing time information via mobile terminal

Abstract

The invention provides a method and a system for a mobile terminal to acquire time information. In the method, the mobile terminal launches a GPS location request in the need of acquiring present time information; the satellite positioning or the information interaction between the network base stations is implemented via GPS / AGPS; the GPS time information is acquired by the positioning information or the interaction information; the time format of the GPS time information is converted into the system time format of the mobile terminal; the time of the terminal equipment is synchronized with the GPS time, and is displayed for users on the terminal equipment. The invention makes use of GPS / AGPS positioning technology utilized more and more universally on mobile terminals to acquire system time, which not only increases the usage of mobile terminals with the function of GPS / AGPS, but also enhances the accuracy of the time system of mobile terminal equipment with the function of GPS / AGPS.

Description

Technical field [0001] The present invention relates to the field of mobile communication, and in particular, to a method and system for acquiring time information by a mobile terminal based on GPS (Global Positioning System) / AGPS (Assisted Global Positioning System). Background technique [0002] With the rapid development of social economy, the scope of people's activities is getting bigger and bigger, and the uncertainty is getting bigger and bigger. Among the various uncertain factors, time, location, etc. have more and more important influences on people's own activities. Today, when mobile terminals (including mobile phones, PDAs, data cards and other related products) are widely used, people’s requirements for location and time information not only stem from the needs of the entire mobile network, but also for users themselves. Normal life is also very important. [0003] Currently, one of the traditional methods for a mobile terminal to obtain a location is to obtain it b...

Problems solved by technology

[0007] A practical problem in the above solution is that if the user moves from one time zone to another, the time needs to be manually modified. For example, the United States itself has four time zones. If the user travels frequently, he needs to maintain his own terminal continuously. time

Another problem is that due to the stability of the mobile terminal time chip, it is likely that the user's time statistics will not be very accurate, and the user will not be able to get the correct time display; In an environment without CDMA network coverage, users will not be able to get the time

[0008] Therefore, it would undoubtedly be ideal if the GPS or AGPS positioning function can be reasonably utilized to overcome the defects in the method of using a time chip to obtain time, however, the technology related to this has not yet been realized
