Embodiment
Below in conjunction with each accompanying drawing, the main of embodiment of the present invention technical scheme is realized principle, embodiment and set forth in detail the beneficial effect that should be able to reach.
Embodiment one
As shown in Figure 2, be the terminal equipment localization method flow chart in the embodiment of the present invention one, its concrete handling process is as follows:
Step 21, when meeting the orientation triggering condition preset, obtains the location factor of terminal equipment to be positioned.
The embodiment of the present invention one proposes, and pre-sets orientation triggering condition, and when meeting orientation triggering condition, terminal equipment positions process.Wherein, orientation triggering condition can be, but not limited to comprise following three kinds of situations:
The first situation, adopts time heartbeat strategy to arrange orientation triggering condition, pre-sets each terminal equipment point positioning time, when arriving the terminal equipment preset and putting positioning time, confirms to meet orientation triggering condition.Wherein, the time interval between adjacent positioned time point is positioning intervals, can be, but not limited to adopt the form that positioning intervals is set to arrange stipulated time point, such as, arranging positioning intervals is 5 minutes, then from terminal equipment normally works, just arranged every 5 minutes one positioning time point, if the time point that terminal equipment normally works is 8: 30, then positioning time of arranging point be 8: 30,8: 35,8 40 ..., the like.
The second situation, adopt base station signal to change strategy and orientation triggering condition is set, terminal equipment is when normally working, the base station of surrounding is detected with regard to needing every a fixed time interval, obtain the information of each base station detected, wherein, the packets of information of base station is containing the mark of base station and the signal strength signal intensity of correspondence, if in each base station of detecting, information and the last time of at least one base station are detected the information obtained and there occurs change, then think that terminal equipment may have occurred position and moves, now confirm to meet orientation triggering condition.Wherein, the information of base station changes, and can change for the mark of base station, also can there occurs change for the signal strength signal intensity of base station.Such as, terminal equipment is when detecting the base station of surrounding, detect 3 base stations, be respectively base station 1, base station 2 and base station 3, obtain the information (mark of base station and signal strength signal intensity) of each base station, after fixed time interval, terminal equipment is detected the base station of surrounding again, detect above-mentioned 3 base stations, and obtain the information of above-mentioned 3 base stations, but the signal strength signal intensity this time detecting the base station 1 obtained is less than the last signal strength signal intensity detecting the base station 1 obtained, that is, the signal strength signal intensity of base station 1 there occurs change, now terminal equipment confirms to meet orientation triggering condition.
The third situation, adopt WIFI signal to change strategy and orientation triggering condition is set, terminal equipment is when normally working, the WIFI signal of surrounding is detected with regard to needing every a fixed time interval, obtain the information of each WIFI AP detected, wherein, the packets of information of WIFI AP is containing the mark of AP and the signal strength signal intensity of correspondence, if in each WIFI AP of detecting, information and the last time of at least one AP are detected the information obtained and there occurs change, then think that terminal equipment may have occurred position and moves, now confirm to meet orientation triggering condition.Wherein, the information of AP changes, and can change for the mark of AP, also can there occurs change for the signal strength signal intensity of AP.Such as, terminal equipment is when detecting the WIFI signal of surrounding, detect 3 WIFI AP, be respectively AP1, AP2 and AP3, obtain the information (mark of AP and signal strength signal intensity) of each AP, after fixed time interval, terminal equipment is detected the WIFI signal of surrounding again, detect these 3 AP of AP2, AP3 and AP4, and obtain the information of these 3 AP, therefore the mark of this AP detected is different with the mark of the AP that the last time detects, therefore terminal equipment confirms to meet orientation triggering condition.
The embodiment of the present invention one proposes, as long as meet any one situation in above-mentioned three kinds of situations, then confirms to meet orientation triggering condition.Such as, when arriving the terminal equipment preset and putting positioning time, confirm to meet orientation triggering condition; If do not arrive default terminal equipment point positioning time, but in each base station of detecting, the information of certain base station there occurs change, then confirm to meet orientation triggering condition; If do not arrive default terminal equipment point positioning time, but in each WIFI AP of detecting, the information of certain AP there occurs change, then confirm to meet orientation triggering condition.
When meeting orientation triggering condition, first obtain terminal equipment and position required information, in the embodiment of the present invention one, the location factor is called by positioning required information, the location factor obtained comprises the information of each base station that terminal equipment detects, and the information of each WIFI AP that terminal equipment detects.Wherein, the information of base station can regard the information pair be made up of the mark of base station and corresponding signal strength signal intensity as, the information of WIFI AP can regard the information pair be made up of the mark of AP and the signal strength signal intensity of correspondence as, and the location factor that terminal equipment obtains is actually by each information formed set.
Therefore, terminal equipment is when locating, using the information of the base station that detects and WIFI AP all as the location factor, so location-server is when positioning according to location factor pair terminal equipment, just can according to positioning strategy, in the factor of location, select required information to position terminal equipment, location-server also can change positioning strategy as required, therefore, it is possible to improve the flexibility of terminal equipment location.Such as, location-server can only position terminal equipment according to the information of base station, also only can position terminal equipment according to the information of WIFI AP, can also position according to the information of the information of base station and WIFI AP to terminal equipment.
Step 22, in the location factor of this locality storage and the positional information of correspondence thereof, confirms that the similarity with this location factor obtained meets the location factor of default similarity condition.
Because terminal equipment is when positioning, the location factor of (that is, terminal equipment stores) and the positional information of correspondence thereof can be stored with reference to local, therefore also the location Summing Factor positional information of storage can be called the position reference information of terminal equipment.
Step 23, is defined as positional information that described terminal equipment is this time located by the positional information that the location factor pair confirming as satisfied default similarity condition is answered.
The embodiment of the present invention one proposes, terminal equipment is after getting the location factor, the no longer direct location factor being carried in Location Request sends to location-server, but first in the location factor of this locality storage and the positional information of correspondence thereof, confirm that the similarity with this location factor obtained meets the location factor of default similarity condition, if there is the location factor meeting default similarity condition with the similarity of this location factor obtained in the local location factor stored, then can think that the current present position of terminal equipment is very close with the local position corresponding to the factor of location meeting default similarity condition stored, wireless environment and the physical environment of terminal equipment do not change, so the current present position of terminal equipment just can be approximated to be same position with the local position corresponding to the factor of location of presetting similarity condition that meets stored, therefore, the positional information that the location factor pair meeting default similarity condition that this locality now can directly store by terminal equipment is answered is oriented as this, the positional information of the current present position of this terminal equipment.
If the similarity that there is not the location factor obtained with this in the local location factor stored meets the location factor of default similarity condition, then can according to existing positioning flow, this location factor obtained is carried in Location Request and sends to location-server, location-server is according to the positional information of the current present position of factor determination terminal equipment, location received, then will to determine, the positional information of the current present position of this terminal equipment returns to this terminal equipment, and the corresponding positional information of preserving the described location factor and server and returning on the terminal device.Wherein, according to existing, location-server can determine that mode is to determine the positional information of the current present position of terminal equipment, idiographic flow repeats no more here.
In the embodiment of the present invention one, the local location Summing Factor positional information stored can prestore, also can store in position fixing process, if the current positional information of terminal equipment obtains with reference to the local location Summing Factor positional information stored, the location factor of current positional information and correspondence then can be stored in the implementation in this locality, also can not store current positional information and the location factor, not affect the realization of the embodiment of the present invention; And if the current positional information of terminal equipment is that server returns, then need to store current positional information and the location factor in this locality.
In the embodiment of the present invention one, the positional information of terminal equipment can be, but not limited to the latitude and longitude information into terminal equipment present position.
More than locate the factor and positional information storage mode and strategy and be applicable to other embodiments of the invention.
Embodiment two
Because the distance of terminal equipment movement is at short notice not too large, therefore, the embodiment of the present invention two proposes, and this location factor obtained and the location factor obtained during last location only can be carried out similarity-rough set by terminal equipment.To this, as shown in Figure 3, the embodiment of the present invention two proposes the specific implementation one of method of locating terminal, and its concrete handling process is as follows:
Step 31, when meeting the orientation triggering condition preset, obtains the location factor of terminal equipment to be positioned.
Step 32, the similarity of the location factor obtained when determining that the location factor this time obtained stores with this locality, last location.
The location factor obtained due to terminal equipment is actually by each information formed set, each information is to the element can regarding this set as, therefore calculating the similarity between two location factors, is in fact exactly the similarity between calculating two set.Wherein, can be, but not limited to adopt the mode of vector space distance to calculate two similarities of locating between the factor, namely calculate the space length between two location factor pairs set of answering, then determine the similarities between two location factors according to the space length calculated.Space length between two location factors is nearer, then show that two location factors are more similar, similarity so between these two the location factors is higher, on the contrary, space length between two location factors is far away, then show that two location factors are more dissimilar, the similarity so between these two the location factors is lower.
Wherein, the embodiment of the present invention two can be, but not limited to adopt existing Similarity Measure mode to calculate two similarities of locating between the factor, and idiographic flow repeats no more here.
Step 33, judges whether the similarity determined is less than default similarity threshold, is less than, then goes to step 36, be not less than, then go to step 34 if judge if judge.
Wherein, similarity threshold can for by learn the priori value obtained to the positional information oriented of location Summing Factor obtained when positioning in certain period.
Step 34, the location factor obtained during the last time location this stored confirms as the location factor meeting and preset similarity condition.
The embodiment of the present invention two proposes, pre-set similarity threshold, when the similarity that step 32 is determined reaches this similarity threshold (being namely not less than this similarity threshold), illustrate that the location factor this time obtained is closely similar with the location factor obtained during last location, so just can think terminal equipment this time location time the wireless environment of wireless environment when locating with the last time with physical environment compare with physical environment, do not change, that is, do not carry out position in the time period of terminal equipment between this twice positioning action to move, the positional information that the positional information that therefore can directly use the last time to orient is oriented as this.
Step 35, is defined as positional information that described terminal equipment is this time located, terminates this positioning flow by the positional information that the location factor pair confirming as satisfied default similarity condition is answered.
In addition, the terminal equipment location factor that also this can be obtained and the positional information corresponding stored determined.
Step 36, is carried at this location factor obtained in Location Request and sends to location-server.
If the similarity that step 32 is determined does not reach similarity threshold (being namely less than similarity threshold), then illustrate that the location factor this time obtained is dissimilar with the location factor obtained during last location, so just can think terminal equipment this time location time the wireless environment of wireless environment when locating with the last time with physical environment compare with physical environment, there occurs change, the similarity that therefore can confirm not exist in the local location factor stored the location factor obtained with this meets the location factor of default similarity condition.
Step 37, receives positional information that location-server returns, the current present position of this terminal equipment, and the described location factor and positional information correspondence is preserved, and terminates this positioning flow.
Embodiment three
As shown in Figure 4, the embodiment of the present invention three proposes the specific implementation two of method of locating terminal, and its concrete handling process is as follows:
Step 41, when meeting the orientation triggering condition preset, obtains the location factor of terminal equipment to be positioned.
Step 42, for each location factor that this locality stores, determines the similarity of this location factor and this location factor obtained respectively.
Step 43, for each location factor that this locality stores, judging whether the similarity determined is less than default similarity threshold, is less than, then goes to step 46 if judged result is respectively, if having a judged result at least for being not less than, then going to step 44.
Judged result is that the location factor that this locality corresponding to a similarity maximum in the similarity be not less than stores confirms as the location factor meeting and preset similarity condition by step 44.
If in the local each location factor stored, a similarity of locating the factor and this location factor obtained is only had to be not less than similarity threshold, then terminal equipment directly can select this location factor, and this location factor is confirmed as the location factor meeting and preset similarity condition.
If in the local each location factor stored, two similarities of locating the factor and this location factor obtained are had at least to be not less than similarity threshold, then terminal equipment can be select a maximum similarity in the similarity be not less than in judged result, then the location factor that this locality corresponding for the similarity selected stores is confirmed as the location factor meeting and preset similarity condition, the location factor so selected is the most similar to the location factor that this obtains, the position that the location factor pair selected is answered is the most close with the position that this location factor pair obtained is answered, thus effectively can improve the accuracy of terminal equipment location.
