Description
Technical field
The present invention relates to the communications field, be specifically related to a kind of GPS (global positioning system) localization method and system.
Background technology
Running fix is a kind of new function that mobile radio communication provides.Obtain location information of terminals by wireless location technology, offer user, mobile communication network or other external entity, realize the various application relevant with the position.Combine GPS, CDMA1X (CDMA group data switching network), GIS (GIS-Geographic Information System), INTERNET network and technology.
Because it is positioning service becomes more and more important, also more and more based on the various application of this service.At present, wireless network assistant GPS location and CDMA triangulo operation positioning function can be embedded among the CDMA terminal chip,, finally form the GPSOne hybrid location determination technology so that above-mentioned two kinds of location technologies are organically blended.
GPSOne has three kinds of locate modes:
(1) mobile phone auxiliary mode (MS-ASSITED)
The location of terminal is undertaken by location-server, and terminal only helps out.The concrete operations principle is as follows: terminal can calculate from the approximate location in certain zone by relatively transmitting a signal to the time difference of each base station.Then this information is issued location-server; Location-server obtains the operation information of satellite, finds out 4-5 the satellite nearest apart from this terminal according to the approximate location at terminal place again, again the positional information of these satellites is issued mobile phone.Terminal obtains positional information via satellite, adds the information of time delay and issues location-server again; Come the physical location of accurate Calculation terminal by location-server, more final result is issued terminal.
(2) handset mode (MS-BASED)
First time of terminal, the location was undertaken by location-server, and location afterwards is all by terminal processes, and described first time, location process and MS-ASSITED were similar.Terminal is downloaded the operation information of all satellites as required from location-server later on, and finds out apart from self nearest 4-5 satellite, obtains gps signal from these satellites then, and self does location Calculation.
(3) stand-alone mode (STANDALONE)
Use traditional GPS locate mode, the discord location-server is mutual; Terminal self is mutual with all satellites, finally obtains positional information.
According to the characteristics of above-mentioned three kinds of patterns, every kind of pattern wherein all has the pluses and minuses of self as can be known, is fit to use in different scenes.Wherein, the mobile phone auxiliary mode can directly obtain terminal positional information by network, do not need mobile phone self to remove to carry out positioning action, but this pattern needs network support, very poor even do not have under the situation of network in network environment, and this pattern can't successfully be located under the occupied situation of Internet resources; Stand-alone mode then positions by the behavior of terminal self fully, do not need network support fully, in case the environment (as indoor) that terminal can't effectively be connected with satellite occurs, the location also is unsuccessful under this pattern, and the time-delay of first location is also bigger, and success rate is on the low side; Handset mode had both required network support, also needed terminal to be in the open environment that can effectively be connected with satellite, and the possibility of location failure is bigger, generally can be used as replenishing of aforementioned two kinds of station-keeping modes.
Because handset mode all needs terminal to be connected satellite according to satellite information with stand-alone mode, so the satellite information that is kept in the terminal under these two kinds of patterns can be shared; And terminal also can be obtained satellite information and is saved in the terminal under the mobile phone auxiliary mode, but owing to be not directly to connect satellite to obtain positional information under this pattern, therefore the satellite information under this pattern can not be that other patterns are used.
In the communication terminal on the market, do not have a kind of can the assurance and can both realize positioning function in real time quickly and accurately under the at any time any state of terminal at present, this is unfavorable for the raising of positioning performance and user satisfaction.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of GPS localization method and system, guarantees that terminal can both realize positioning function quickly and accurately under the overwhelming majority's scene, improves positioning performance and user satisfaction.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of GPS localization method, this method comprises:

The aforesaid operations thinking may further comprise the steps:
Steps A. start finishes, and waits sign on to be positioned.After receiving instruction, refresh cycle number of times of initialization, operating procedure B;
Need to prove, because star chart has the term of validity, the therefore cycle times that need be provided for refreshing at star chart.
Step B. detects whether network state is available, if available, forwards step C to; Otherwise execution in step D;
Step C. utilizes mobile phone auxiliary mode location once, if successfully obtain data, forwards step e to; Otherwise, execution in step B;
Step D. utilizes the stand-alone mode location once, if successfully obtain data, notes related satellite information; Otherwise, execution in step B;
Step e. whether be available, if available, forward step F to if detecting network state; Otherwise a short timer (as 1 minute) is set, and timer is to re-executing step e constantly;
Step F. judge the refresh cycle number of times, if be not 0, execution in step G; If the refresh cycle number of times is 0, do not do any operation;
Step G. locatees once with handset mode, and the location is returned back refresh cycle number of times and subtracted one, and a long-time timer (as 60 minutes) is set, and timer is to re-executing step e constantly.
As seen, compared with prior art, the present invention is directed to the pluses and minuses of various locate modes, before each location, judge the current network state of terminal, select corresponding station-keeping mode.When the failure of location, the fault-tolerant processing that continues the location is arranged also, guaranteed the success rate of location to a great extent.At the slow problem in the first location of stand-alone mode, also be provided with an operation especially: periodically do the one-time positioning operation with mobile phone auxiliary mode (but network time spent) or stand-alone mode (when network is unavailable), so that the current effective satellite information is kept in the terminal.Like this, when receiving Location Request, use stand-alone mode if desired and locate, because preserved effectively satellite information, the effective positioning action of realization that terminal also can be very fast before.
Simultaneously, be provided with the one-period number of times at the above-mentioned cycle,, illustrate that the user of this terminal does not have location requirement if terminal is not received Location Request for a long time.This can stop after periodically operating in and carrying out a period of time automatically, and when triggering, periodic operation just restarts as Location Request.
Below, present invention is described in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 1 is the GPS positioning flow figure of the embodiment of the invention, and this flow process may further comprise the steps:
Step 101b. terminal is received Location Request, reinitializes the refresh cycle number of times, execution in step 102;
Whether step 102. detects network state available, if available, forwards step 104 to, otherwise execution in step 103;
Whether step 105. detects network state available, if available, forwards step 107 to; Otherwise, forward step 106 to;
In conjunction with above-mentioned flow process as can be known, GPS location technology of the present invention has operation thinking as shown in Figure 2.Referring to Fig. 2, Fig. 2 is a GPS positioning flow sketch of the present invention, and this flow process may further comprise the steps:
