As shown in Figure 6, the workflow that the service of one whole is provided for the user has been described.To carry out detailed elaboration step by step to whole flow process below.
S601, mobile phone is opened positioning service.S602, whether client inspection mobile phone if mobile phone be not in talking state, then gets into S604 in talking state, notifies the user can't start positioning service, stops positioning service.If mobile phone is a talking state, then get into S603, send request for location services to location-server, the other side's mobile phone is positioned.
After S605, server receive the client sent request, begin correspondent is positioned.Judge that whether distance between the other side's mobile phone and this mobile phone is greater than short distance standard (being predeterminable range); This algorithm is specific as follows: locate from big to small according to geographic range; If both call sides just can be directly to the client return results fully from different countries and regions; If in identical countries and regions, just locate with less geographic range and calculate both sides between shift value.The shift value that calculates (in order to narrate conveniently, is designated as a to this shift value
0) three kinds of situation are arranged: first kind of situation, shift value meet short distance standard (in order to narrate conveniently, being made as m to the short distance standard), can position and let client show the map of drawing; Second kind of situation according to a rational algorithm, thought in the time interval that the user can bear, and shift value can change to from currency and meet the short distance standard, will after this time interval, position once more so, and judge again; The third situation according to a rational algorithm, thinks that shift value can not meet the short distance standard in the time interval that the user can bear, then will point out user's location condition not meet, and temporarily stop positioning service.The short distance standard m here can set according to the different service needs, surpasses 1KM but must not advise.If scope is excessive, can moment increases the pressure of Network Transmission, and influence the accuracy of data and the accuracy of image.Secondly, if can not draw out effective image in the short time, can greatly destroy the value that user experience and the present invention itself exist.The present invention does different processing procedures for above three kinds of situation.
S606, to above-mentioned first kind of situation, shift value is less than the short distance standard, and the notice client begins to draw, and progressively sends to client to the cartographic information data of client needs, coordinate etc.
S607, to above-mentioned second kind of situation, the displacement standard of coming out according to reasonable algorithm computation is designated as b, b should be one with the relevant value of short distance standard m, generally be made as the value of the product of number and m between 2 ~ 9.If a
0Greater than m and less than b, promptly above-mentioned second kind of situation then carried out S611; If a
0Greater than b, promptly above-mentioned the third situation is then carried out S610, promptly stops positioning service.
S611 calculates positioning time next time at interval.Interval coefficient k computing time of elder generation
0=(a
0-m)/and m, then at k
0After multiply by the time interval T of a constant, calculate the shift value of this mobile phone and the other side's mobile phone again, and remember that this time interval is t
0The constant T here also can set according to the different service needs.
S612, the displacement calculating value remembers that the displacement between the other side's mobile phone and this mobile phone is a once more
1If, a
1Greater than a
0, think both sides be in away from trend, then carry out S610, promptly suspend positioning service; If a
1Less than a
0And, think that both sides are in the trend of approaching, and then jump to S611 greater than m.
Be noted that at S611 both sides' shift value changes between the b at m, and possibly needing iteration for several times in the approximate procedure gradually; Except for the first time; When locating and calculate the time interval of location next time at every turn, be in the above time interval, both sides' relative average speed is as parameter.For example, the average speed v=(a of calculating in a last time interval
1-a
0)/t calculates the time interval t=(a of location next time
1-m)/and v, so just should behind time interval t, locate once more and the displacement calculating value.Like this both sides' relative velocity bigger (promptly approach and away from speed fast more), the time interval is just short more.
S613; In case the displacement between the other side's mobile phone and this mobile phone less than m, just jumps to S606, just notify this Mobile Phone Locating to the other side's mobile phone; And beginning is drawn at this mobile phone interface; Draw the roughly physical environment in the short-range, and, mark the position of this mobile phone and the position and the direction of direction and the other side's mobile phone through the direction inductor equipment on the mobile phone.
S608; Up to end of conversation, the continuous updating interface is along with the displacement between two mobile phones is dwindled; The drafting of physical environment that can represent two mobile phone relative displacements is progressively accurate, can not the physical environment of the relative position of two mobile phones of accurate description no longer be continued to draw.Along with reducing of both call sides relative displacement, the scope of the physical environment that need draw is more and more littler, but more and more accurate, and only draws the physical environment that helps to simulate the true relative position of both sides, up to end of conversation.And in communication process, client and location-server carry out data communication always, are used for drawing accurate more physical environment.
If converse with the multi-section mobile phone, the mobile phone of just each one being conversed positions, and the positioning result to each mobile phone carries out above-mentioned verification and calculating then, and only sends to this mobile phone to the data of satisfactory correspondent.
In communication process; If a side has opened this fixed service earlier; Open positioning service behind the opposing party and communicate by letter with location-server; Location-server can be opening earlier the locator data copy that a side obtains, and send to the side that positioning service is opened in the back, like this after can the reaching and position drawing faster of unlatching positioning service.For the situation of MPTY, will the locator data that has obtained be copied to each correspondent.Behind the end of conversation, stop positioning service.Being saved in the memory cell of client after the integration of the data of this location, so that reuse later on.
According to technical scheme of the present invention, the portable terminal of conversing can carry out the real-time interactive location, makes things convenient for both call sides to obtain the other side's position.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
