Embodiment three:
In another embodiment of the present invention, disclose a kind of geographical dictionary method for pushing, as it is shown on figure 3, include:
Step 300, creates the seedbed reason dictionary including multiple geographic terms, and described geographic terms has at least one index position;
Step 320, receives the current geographic position that mobile terminal sends;
Step 340, it is determined that the geographical dictionary of son that in the reason dictionary of described seedbed, the index position geographic terms described current geographic position of composition in described current geographic position preset range is corresponding, and push described son geographical dictionary extremely described mobile terminal.
First dictionary server creates the seedbed reason dictionary including numerous geographic terms, and wherein, each geographic terms has at least one index position, and the index position of different geographic terms is likely to identical. Wherein, geographic terms includes the terrestrial references such as building title, road name, cell name, Business Name, food and drink and supermarket title. The index position of geographic terms is the position coordinates of the terrestrial reference that this geographic terms represents. Seedbed reason dictionary can also include other information, as geographic terms indexes coding, geographic terms attribute etc. Following table is an example of entry in the reason dictionary of seedbed:
In above table, each geographic terms is provided with at least one index position and is called the geographic terms of " industrial and commercial bank " for name, there is multiple site in industrial and commercial bank in Beijing, the corresponding index position in each site, such as geographic terms " Hepingli subbranch of industrial and commercial bank ", corresponding index position is (x1,y1); The index position that geographic terms " Site of Qing Hua Yuan subbranch of industrial and commercial bank " is corresponding is (x2,y2); And the index position of geographic terms " industrial and commercial bank " correspondence includes multiple, as: (x1,y1)、(x2,y2)、(x3,y3)、(x4,y4)、(x5,y5) .... The index position of geographic terms is the position coordinates of all terrestrial references of this geographic terms mark, and described position coordinates can adopt latitude and longitude coordinates can also adopt the plane rectangular coordinates on map.
Still above table is example, and the such as latitude and longitude value in Tian An-men, Beijing is respectively as follows: north latitude 39 degree 54 points 26.37 seconds, east longitude 116 degree 23 points 29.22 seconds, if representing position coordinates with latitude and longitude coordinates, then and x9=116.403875, y9=39.915168, the index position in Tian An-men can be expressed as (116.403875,39.915168), and wherein x is longitude, and y is latitude value.
When being embodied as, if represent the position coordinates of terrestrial reference that entry is corresponding with the plane rectangular coordinates on map, then can pre-build the plane right-angle coordinate of map, such as, initial point using Tian An-men, Beijing as map plane rectangular coordinate, east orientation is X-axis negative direction, west is y-axis negative direction to being y-axis positive direction, south orientation for X-axis positive direction, north orientation, then, according to actual range, convert out the coordinate figure (x of other terrestrial references, y), as the index position that the geographic terms representing this terrestrial reference is corresponding. Such as, the index position in Tian An-men is (0,0).
When being embodied as, seedbed reason dictionary adds index coding, be easy to after generating the geographical dictionary of son, when mobile terminal carries out information input, carry out entry coupling rapidly according to the character code of input. Such as, user is when interface of input method input " industry and commerce " of the silver of mobile terminal, input method is extracted the coding " GS " of input character and is carried out fuzzy matching with the index coding in sub-geography dictionary, it is determined that the index that the match is successful is encoded to " GSYH ", then export the entry that this index coding is corresponding.
And the tone attribute in the reason dictionary of seedbed can also carry to the geographical dictionary of the son generated, it is possible to reduce the scope of geographic terms coupling according to the type of application in mobile terminal. Such as, user is when the bank client of mobile terminal inputs information, the information of input can only be bank outlets, then bank client has only to carry out mating in the geographic terms that attribute is bank, the all entries in needing antithetical phrase geography dictionary do not mate one by one, effectively reduce entry matching range, improve the efficiency of input information.
After only establishing seedbed reason dictionary, the current geographic position that dictionary server could send according to the mobile terminal received in step 320, generate the current geographic position geographical dictionary of corresponding son further.
In above-mentioned steps 340, after receiving the current geographic position that mobile terminal sends, first, the index position of the geographic terms of storage in dictionary server ergodic source geography dictionary, screens geographic terms according to preset range. Such as, the geographic terms that screening is corresponding less than the index position of threshold range with described current geographic position distance is as the geographical dictionary of the son that described current geographic position is corresponding; Or select index position to be positioned at the geographic terms of rectangular area of the default length of side centered by described current geographic position as the geographical dictionary of the son that described current geographic position is corresponding. Then, described dictionary server will push described son geographical dictionary extremely described mobile terminal. Screen geographic terms according to the distance between two geographical position, calculate more convenient; Determining a rectangular area centered by current geographic position, the geographic terms that location index in this region of reselection is corresponding is more suitable for the mobile terminal geographical dictionary of the son to receiving and carries out visualization display, and two kinds of screening schemes are respectively arranged with feature. Those skilled in the art is on present disclosure basis, it is also possible to selecting other screening technique, this is not limited by the application. Preferably, determine that in the reason dictionary of described seedbed, the geographic terms corresponding less than the index position of threshold range with described current geographic position distance forms the described current geographic position geographical dictionary of corresponding son according to described index position.
Below to illustrate to determine the geographic terms corresponding less than the index position of threshold range with described current geographic position distance in the reason dictionary of the described seedbed detailed process as the geographical dictionary of the son that described current geographic position is corresponding according to described index position according to the distance screening geographic terms between two geographical position.
First the distance of the location index in the reason dictionary of seedbed and described current geographic position is calculated respectively. When being embodied as, the difference according to the representation of index position, adopt diverse ways to calculate the distance between two geographical position.
When representing index position with plane rectangular coordinates, all location indexs in dictionary are managed for seedbed, it is utilized respectively formula S=R arccos [cosy1cosy2cos (x1-x2)+siny1siny2], calculates the distance S between all location indexs in the reason dictionary of seedbed and the current geographic position of mobile terminal transmission. In above-mentioned formula, in above-mentioned formula, the coordinate figure of location index in dictionary is managed in current geographic position and seedbed that (x1, y1), (x2, y2) respectively mobile terminal send. If x1 is the longitude of mobile terminal current location, y1 is the latitude value of mobile terminal current location, then x2 is the longitude of index position in the reason dictionary of seedbed, y2 is the latitude value of index position in the reason dictionary of seedbed, and R is earth radius.
When representing index position with latitude and longitude coordinates, all location indexs in dictionary are managed for seedbed, is utilized respectively formulaCalculate the distance S between all location indexs in the reason dictionary of seedbed and the current geographic position of mobile terminal transmission. In above-mentioned formula, the coordinate figure of location index in dictionary is managed in current geographic position and seedbed that (x1, y1), (x2, y2) respectively mobile terminal send.
Then, successively the distance AB of calculated each index position and described mobile terminal current location and threshold range are compared, when distance S is less than described threshold range, the index position thinking corresponding for this distance S meets preset rules, and the geographic terms belonging to index position corresponding for this distance S adds current geographic position the to be pushed geographical dictionary of corresponding son.
If selection index position is positioned at the geographic terms of the rectangular area of the default length of side centered by described current geographic position as the geographical dictionary of the son that described current geographic position is corresponding, then first-selection calculates the minimum abscissa Xmin of rectangular area, maximum abscissa Xmax, minimum vertical coordinate Ymin, maximum ordinate Ymax according to current geographic position and the default length of side; Then, judge the index position in the reason dictionary of seedbed respectively, coordinate (x when described index position, y) meet: < y is < during Ymax for Xmin < x < Xmax and Ymin, by index position, (x, the geographic terms belonging to y) adds current geographic position the to be pushed geographical dictionary of corresponding son.
The present invention is by creating the seedbed reason dictionary including multiple geographic terms, and described geographic terms has at least one index position; Then the current geographic position sent according to the mobile terminal received, determine that in the reason dictionary of described seedbed, index position geographic terms in described current geographic position preset range forms the sub geographical dictionary that described current geographic position is corresponding, and push the current geographic position that the geographical dictionary of described son sends to described mobile terminal reception mobile terminal. The geographical dictionary of son owing to generating is relevant with current geographic position, namely ensure that the accuracy of the geographical dictionary of son, compared with pushing whole city geographic terms with prior art, effectively reduces the volume of dictionary.

When being embodied as, after completing the propelling movement current geographic position geographical dictionary of corresponding son, described method also includes: dictionary server record pushes to the identity of described mobile terminal corresponding to the geographical dictionary of son of described mobile terminal, the geographical position corresponding with the geographical dictionary of described son. Every lines storehouse server to push the geographical dictionary of son for multi-section mobile terminal, and, position according to mobile terminal, repeatedly push, therefore, in order to different mobile terminals is pushed history by recording needle, dictionary server can record unique mark of mobile terminal, such as device mac address, and the feature of the geographical dictionary of son pushing to this mobile terminal, as: the geographical position of the mobile terminal that this son geography dictionary is corresponding.
After dictionary server receives the current geographic position that mobile terminal sends, described according to described index position determine described seedbed reason dictionary in corresponding less than the index position of threshold range with described current geographic position distance, and the front geographic terms once not having pushed to a described mobile terminal forms the described current geographic position geographical dictionary of corresponding son, farther include: according to index position determine the current geographic position distance sent with described mobile terminal less than threshold range wait push geographic terms; Search the identity of the described mobile terminal of record, it is determined that the front historical geography position that once the pushed geographical dictionary of the son to this mobile terminal is corresponding; Wait described in determining to push in geographic terms with described historical geography positional distance more than or equal to threshold range wait push the geographic terms once not having pushed to described mobile terminal before geographic terms is; By determine described before once do not have the geographic terms of pushed to described mobile terminal to form the geographical dictionary of son.
Described according to index position determine the current geographic position distance sent with described mobile terminal less than threshold range wait push geographic terms detailed process referring to embodiment three, repeat no more herein.Determining after pushing the geographical dictionary of son, the described dictionary server propelling movement history according to this mobile terminal, the described entry waiting to push in the geographical dictionary of son is screened, the geographical tone comprised in the geographical dictionary of son once pushed before filtering, namely once there is no the geographic terms of pushed to described mobile terminal before only retaining, before once pushed to the geographic terms of described mobile terminal and be not repeated to push, the effective volume reducing the geographical dictionary of son. When being embodied as, described dictionary server coupling in the identity of the described mobile terminal of record sends the identity of the mobile terminal of current geographic position. If the match is successful, before this mobile terminal is described, once push the geographical dictionary of son, then, further determine that the geographical position that the geographical dictionary of described son is corresponding. Waiting to push the distance of index position and described historical geography position in the geographical dictionary of son described in calculating respectively, distance is more than or equal to the geographic terms treating once not have pushed to described mobile terminal before propelling movement geographic terms is of threshold range; Push determine described before once do not have the geographic terms extremely described identity of pushed to described mobile terminal corresponding mobile terminal.
Mobile terminal A sends after obtaining current geographic position m to dictionary server, and dictionary server receives the current geographic position that mobile terminal sends; Then, dictionary server determines that in the reason dictionary of the seedbed pre-build, index position geographic terms in described current geographic position preset range forms the described current geographic position geographical dictionary L of corresponding sonm, as managed in seedbed, dictionary filters out all geographic terms composition geographical dictionary L corresponding less than the index position of threshold range with m distancem, and push the geographical dictionary L of described sonmTo described mobile terminal A. Then, the geographical position of mobile terminal A is switched to n, mobile terminal A sends to dictionary server after obtaining current geographic position n, when dictionary server receives the current geographic position n that mobile terminal sends, first manage in dictionary filtering out all geographic terms corresponding less than the index position of threshold range with n distance and form and wait to push dictionary L in seedbedn', then delete Ln' in be concurrently present in middle LmGeographic terms, obtain the geographical dictionary L of sonn。
