Detailed description of the invention
For the technical scheme making to present invention solves the technical problem that, adopting and the technique effect reached clearly, below in conjunction with accompanying drawing, the technical scheme of the embodiment of the present invention is described in further detail, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments。Based on the embodiment in the present invention, the every other embodiment that those skilled in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention。
Refer to Fig. 1, it is the method flow diagram of the first embodiment of the method that a kind of adaptive network of offer positions in the specific embodiment of the invention, as it can be seen, the method for this adaptive network location, including:
Step S11: send initial location request at least two network location service。
Network location service is based on the location of base station and Wi-Fi Hotspot。The general principles of such as architecture is: mobile terminal measures the down-bound pilot frequency signal of different base station, obtain the TOA (TimeofArrival of different base station descending pilot frequency, due in) or TDOA (TimeDifferenceofArrival, the time of advent is poor), according to this measurement result and in conjunction with the coordinate of base station, it is generally adopted triangle formula algorithm for estimating, it becomes possible to calculate the position of mobile terminal。Actual location-estimation algorithm needs to consider the situation that many base stations (3 or more than 3) position, and therefore algorithm wants complicated a lot；It is said that in general, the number of base stations of moving table measuring is more many, certainty of measurement is more high, and positioning performance improves more obvious。Concrete calculating process realizes based on triangle formula, and various calculating parameters detect acquisition in communication network and mobile terminal。
Being currently able to provide the main body of network location service to have multiple, the namely provider of network location service described in this programme, each provider has the client of correspondence to access the network location service of its offer。In this programme, it is necessary to mobile terminal installs the client of multiple provider in advance to obtain the network location service of correspondence。When carrying out network location service, user can select different providers according to the custom self used with the quality of positioning service。In actual position fixing process, because the provider of each network location service can be obtained with base station, layout different, server region different, main services object place, the region corresponding with the data of Wi-Fi Hotspot is different, in same geographic range, the precision of the geo-localisation information of the provider of different network location services and feedback speed are all different。In the prior art, single mobile terminal is generally only with a network location service, or adopting multiple network location service, but it is fixing for specifically adopting which network location service, same network location service would be likely to occur, in different regions, the locating effect that difference is huge。In order to obtain better network location service, it is necessary to according to each network location service locating effect in concrete territorial scope, the provider adopting which network location service is selected to provide service within the scope of current zone。
Specifically chosen principle is location efficiency, on mobile terminals during electricity, sends initial location request based on corresponding client at least two network location service, to do the velocity measuring of network positions。The provider of each network location service carries out position feedback after receiving initial location request。Concrete feedback procedure is same as the prior art, is not further elaborated at this。
Step S12: the network location service that first returns initial positioning information is confirmed as acquiescence positioning service。
The provider of each network location service is after receiving initial location request, if it is possible to realize location, all can restoring to normal position information。In this programme, network location service by first restoring to normal position information, the network location service that namely comprehensive speed of location and transmission is the fastest confirms as acquiescence positioning service, when subsequent design to positioning service, all send the request of network location service to acquiescence positioning service, receive corresponding location information。
It should be noted that, sending and receive and giving tacit consent to the determination of positioning service of initial location request all completes on mobile terminal backstage, concrete confirmation process is not shown for user, the final use information only receiving real demand when normal request network location service of user。
Step S13: send network location request to acquiescence positioning service when needing to position。
Location when needing location not imply that navigation, but location requirement when referring to use the various application relating to position judgment, for instance point of addition information in photo or photograph album, the take exercise by running route in process and mileage record。In such applications, application itself is likely to not have map or positioning function, but can obtain the location information that network location service provides, it is achieved relevant location requirement。
In sum, initial location request is sent at least two network location service, return speed according to initial positioning information selects the network location service of priority access, using the return speed of location information as the selection standard of network location service, the network location service that adaptive speed is the fastest, improves speed and the probability of success of network location request。
Refer to Fig. 2, it is the method flow diagram of the second embodiment of the method that a kind of adaptive network of offer positions in the specific embodiment of the invention, as in figure 2 it is shown, the method for this adaptive network location, including:
Step S21: send initial location request at least two network location service。
Network location service positions compared to GPS, and locating speed is faster, and affected by environment less, and GPS is likely in the space relatively closed just cannot realize positioning, and network location service can position accurately in indoor realization very much。
Step S22: the network location service that first returns initial positioning information is confirmed as acquiescence positioning service。
First network location service returning initial positioning information is considered as the alignment quality possessing optimum in current region, is confirmed as acquiescence positioning service, and mobile terminal all adopts acquiescence positioning service when needing to carry out network positions in follow-up use procedure。
Step S23: preserve initial positioning information。
In the present embodiment, initial positioning information is preserved further。The acquiescence positioning service that initial positioning information confirms is the network location service providing optimum in a certain regional extent, it is likely to just to ensure service quality beyond this scope, namely initial positioning information is used as position judgment, to ensure the service quality of network location service。
Step S24: send network location request to acquiescence positioning service when needing to position。
To add on photo with taking pictures when concrete application scenarios is such as taken pictures；Or in social tool, issue subsidiary geography information when photo or message。
Step S25: the network positioning information that network location request is returned by acquiescence positioning service carries out address de-parsing。
If the network positioning information that acquiescence positioning service generates, directly carried out address de-parsing by this network positioning information of this acquiescence positioning service team。Network positioning information is based on standardized position and divides the location carried out, for instance longitude and latitude or grid division；The network positioning information generated based on longitude and latitude and grid division is mainly for standardized recorded, and user is individual, only according to the longitude and latitude in network positioning information or grid division cannot be carried out be accurately positioned, it needs that network positioning information is carried out address de-parsing and obtains the address information based on place name。Such as (east longitude: 116 ° 23 ' 30 ", north latitude: 39 ° 54 ' 11 "), ordinary person cannot know the geographical position of its sensing, but can confirm that the geographical position that this network positioning information is corresponding is the Monument to the People's Heroes by address de-parsing。The de-parsing of the location navigated in real life that address de-parsing is accomplished that on geography。
Step S26: the network positioning information received and initial positioning information are compared, confirms the difference value of the two。
Having positioned after every time, the network positioning information received and initial positioning information are compared, confirms the difference value of the two。Difference value i.e. user currently obtain network positioning information and change in location degree when confirming acquiescence positioning service, if altered a great deal, there are the needs reaffirming acquiescence positioning service, if varied less, maintaining current state。
Step S27: when difference value is beyond the threshold value preset, reaffirm acquiescence positioning service。
If the change of difference value is excessive, beyond the threshold value preset, illustrates that change in location is likely to have influence on the quality of network location service, or more excellent network location service can be obtained, now can reaffirm acquiescence positioning service。The process of confirmation acquiescence positioning service is exactly the process of step S21 and step S22 in fact, that is reaffirm that acquiescence positioning service only need to re-execute step S21 and step S22, certainly, reaffirm the demand of acquiescence positioning service during for realizing follow-up change in location, reaffirm that acquiescence positioning service will update the initial positioning information of correspondence every time。
In the present embodiment, it is 2 degree of longitudes or 2 degree of latitudes by threshold settings。
2 degree of longitudes mentioned here or 2 degree of latitudes are to say if 2 degree of changes occur longitude, reaffirm acquiescence positioning service, if 2 degree of changes occur latitude, also reaffirm acquiescence positioning service。It practice, in different positions, the actual range moving 2 degree of longitudes along parallel is likely to difference, for instance the actual range of 2 degree of longitudes of low latitudes is more than the actual range of the 2 degree of longitudes in high latitude area。At this, for judging conveniently, directly it is set as 2 degree of longitudes or 2 degree of latitudes。
Step S28: when time-out reaches preset times continuously in the return of network location request, reaffirm acquiescence positioning service。
If the network location request continuous several times initiated to acquiescence positioning service returns time-out, for instance continuous 3 times, 4 times or 5 times, now can be considered as acquiescence positioning service and cannot return network positioning information, it is necessary to reaffirm acquiescence positioning service。The process specifically reaffirmed is not repeated explanation。
Step S29: when network location request does not return network positioning information, reaffirms acquiescence positioning service。
Network location request does not return network positioning information, illustrates cannot be normally carried out network positions, now reaffirms acquiescence positioning service。The process reaffirmed is identical with the process in step S27 and step S28。
In sum, initial location request is sent at least two network location service, return speed according to initial positioning information selects the network location service of priority access, using the return speed of location information as the selection standard of network location service, the network location service that adaptive speed is the fastest, improves speed and the probability of success of network location request。Meanwhile, when the location information that large change or existing location itself occur in the position of mobile terminal returns abnormal, it is possible to reaffirm default network service, it is achieved the stable quickly location in zones of different。
