Description
Technical field
The present invention relates to moving communicating field, and particularly, relate to a kind of based on GPS (Global Positioning System, global positioning system)/method and system of the capturing time information via mobile terminal of AGPS (Assisted GlobalPositioning System, agps system).
Background technology
Along with high development of social economy, the people's activities scope is increasing, and uncertainty is also more and more big.And in various uncertain factors, time, position etc. are more and more important for the influence of people's own activity.In today that portable terminal (comprising Related products such as mobile phone, PDA, data card) is widely used, people not only come from whole mobile network's needs for the requirement of position, temporal information, and for user self, these essential informations are also very important for user's normal life.
Current, traditional portable terminal obtains the relevant information that one of method of position is to use terminal and network to carry out in the Signalling exchange and obtains, the parameter that is usually expressed as in the signalings such as use such as position renewal, periodic location update or sub-district switching is extracted, this class methods calculated relationship complexity, be difficult to realize, and be not easy on terminal, show in real time.
Another mode that mobile location information shows is to use the implementation method based on GPS (GlobalPositioning System, global positioning system) characteristic.Be used for realizing accurate demonstration by making of GPS technology and its similar technique AGPS (Assisted Global Positioning System, agps system) for customer location.GPS is U.S. army early 1970s at " Transit satellite navigator fix " technical three-dimensional high-precision navigator fix with global, totipotency (land, ocean, aeronautics and space), round-the-clock sexual clorminance that grows up, regularly, velocity-measuring system.The networking of GPS work satellite ensures that global arbitrary moment, arbitrary place all can observe (can reach 11 at most under the unobstructed situation) to the satellite more than 4, realize continuous, real-time navigation and location, regularly, constant speed.
AGPS is the GPS of network assistance, utilize pure GPS location, need position in the place that can receive gps satellite signal, this makes mobile phone users accurate localization fast when indoor positioning, in order to overcome the above problems, can adopt the A-GPS location technology.By being integrated in GPS receiver on the travelling carriage and the GPS auxiliary equipment in the network (as receiving the RGPS station of satellite information), utilize gps system to realize self-align, regularly to travelling carriage.
And portable terminal generally is by built-in time chip in portable terminal for obtaining of time, is provided with by chip timework mechanism and user and finishes obtaining and being provided with of subscriber's local temporal information.This method not only need additionally increase relevant process chip on terminal, also need user oneself that the time manually is set.
The problem of a reality that exists in the such scheme is if the user moves to another time zone from a time zone, then needs modification time manually, such as the U.S. itself four time zones is just arranged, and just needs ceaselessly to safeguard the terminal time of oneself if the user often goes on business.The another one problem is owing to the sexual intercourse of portable terminal time chip working stability, and it is not very accurate probably causing user's time statistics, and the user will can not get correct time showing; If what also have use exactly is the cdma network time, then the user can't obtain the time under the environment that no cdma network covers.
Therefore, if can reasonably utilize GPS or AGPS positioning function overcome defective that service time, chip came to exist in the method for acquisition time be undoubtedly desirable, yet relevant therewith technology still is unrealized at present.
Summary of the invention
Consider the above-mentioned problems in the prior art and propose the present invention, for this reason, the present invention aims to provide a kind of method of capturing time information via mobile terminal, wherein, this method is removed the work chip that the time is provided with on the portable terminal with GPS function, provide the customer mobile terminal current time by the GPS related algorithm.
