Embodiment
As shown in Figure 1, the present invention includes background server and the client-side program that is installed in intelligent mobile terminal.Its core concept is: the user is from the specific geographical position that needs of client input detect, and server finds the corresponding signal characteristic in this geographical position from database, and signal characteristic is sent to subscription client; Client constantly detects the signal characteristic of user's current location; In case finding the signal characteristic of this current location and the signal characteristic in the preassigned specific geographical position of user is complementary; If require high orientation precision; Then further open the GPS transducer and carry out the accurate coupling in geographical position, otherwise can think directly that the user has been positioned at ad-hoc location.When not having the information in above-mentioned specific geographical position in the server database; The nearest geographical position of server data library searching and specific geographical position; And deduce the corresponding signal characteristic in nearest geographical position, and the signal characteristic that deduction obtains is sent to subscription client.
Above-mentioned signal characteristic is any one in the bluetooth equipment of base station code, WIFI access point, unlatching, is that example is explained with the base station code in the present embodiment.
Set up a numerical map interface of supporting function of search in client.When address of user search, server is presented at Search Results and supplies the user to confirm on the numerical map.When the address of user input not during the geographical data bank at server, server is supported fuzzy search, and promptly according to the block, the street shows bulk zone.The user can mark the target geographic position of oneself by hand in the viewing area.Above-mentioned numerical map interface is a technology well known to those of ordinary skill in the art, perhaps gets final product based on Google Maps, Baidu's map search.
Import the information in specific geographical position as the user after, server is searched geographical data bank and is found its corresponding possible some signal characteristics according to the ID in this specific geographical position.If there is not this position in the geographical data bank, server need combine its signal characteristic of data with existing estimation according to its geographical coordinate.If such as adopting base station code as signal characteristic, server will check whether contain in the database apart from 500 meters in this geographical position with interior geographical position so.If exist these to leave the nearer geographical position of target geographic position, then system just returns to client to the base station code in these geographical position.If do not exist, the notifications client can't obtain the signal characteristic in this geographical position so.
The respective signal characteristic in geographical position, geographical data bank the inside is by the manual work collection, and artificial data of gathering are many more, and the accuracy of system and coverage are also just high more, but cost also increases.If adopt base station code as signal characteristic, the method in respective base station code data storehouse, a kind of lower-cost structure geographical position is to utilize the method for exhaustion constantly to call the base station location inquiry API that Google provides.Its specific practice is following: Google provides the open service of returning this base station geographic position according to base station code.So, given city sign indicating number and operator's sign indicating number, if we send the base station location inquiry API that all possible base station code is given Google respectively, the data that we just can obtain thousands of geographical position and respective base station sign indicating number are right.Because the possible base station number in each city is no more than 10000, the time overhead of this method can be accepted fully.
If after successful inquiring, server sent to client with the signal characteristic in specific geographical position, client just began constantly to detect the signal characteristic of user's current geographic position.Such as making signal characteristic with base station code, client need detect the user and whether be positioned at the sea, back now, and its corresponding base station code possibly be A, B, C, D.Once the current serving BS of client terminal to discover is A, B, C, any one among the D, whether the GPS transducer will be opened is positioned at the sea, back so that accurately current location is positioned and checks the user.
Embodiment 2
The service of the disclosed network of frequent access (such as the base station information retrieval service of Google) may be suffered the shielding of Internet service provider.Except the method for the open network service of the utilization of being mentioned in text picked up signal property data base, we also can construct the local signal property data base through the method that signal characteristic collection software is installed at the user mobile phone end.Such as, through the mobile phone end mounted base station information gathering software the user, user's mobile phone end will be regularly obtains the geographical position and the covering radius of this base station with the base station code of newly collecting to the base station information retrieval service of calling Google and providing.Because the visit capacity of unique user is little, this services request can conductively-closed.The signal characteristic information that unique user is collected then can regularly upload to our server.If the user for flow-sensitive, also can only upload the base station code of its discovery and never call external web services.Can there be our server unification to call like this.Compare with instance one, we can only submit the inquiry of true base station code to external web services, have avoided a large amount of invalid base station code inquiry of the method for exhaustion.
The other technologies characteristic is identical with embodiment 1.
Embodiment 3
The coverage of signal characteristic database is limited eventually, particularly at the initial stage of setting up, has a large amount of unlapped geographical position.For these geographical position, we not only do not have corresponding signal characteristic data, even signal characteristic in geographical position all can't obtain near it, to such an extent as to estimation all can't realize.This user for the initial stage can cause very big inconvenience.In order to address this problem, we can adopt following strategy: in subscription client, safeguard a signal characteristic database; Whenever mobile phone detects new signal characteristic, then to the corresponding general geographical position of web service queries signal characteristic.Such as directly or through the base station code information retrieval service that specific acting server calls Google obtaining the corresponding general area of this base station code according to newfound base station code.This signal characteristic and general geographical position thereof are added to mobile phone end signal characteristic database after the successful inquiring.The signal characteristic database that it is pointed out that the user mobile phone end only covers the zone that unique user was visited.
(x y) is provided with sense command, and we can let this user's the local signal characteristic database of mobile telephone scanning whether cover this geographical position if the user is in the geographical position that a server end signal characteristic database can't cover.If the local signal property data base has write down the signal characteristic in current place, mobile phone end just utilizes the local signal property data base to need the signal characteristic of detection for the geographical position generation of user's appointment so.In addition, mobile phone end checks whether newfound signal characteristic can be used for upgrading the original signal characteristic for the generation of user's specified geographic location each when finding new signal characteristic and upgrading the local signal property data base in passing, if having then upgrade.
With the base station code is example; If the user is (x in the geographical position; Y) be provided with sense command and the base station code database of server end does not have the base station information of this position, user's mobile phone end checks at first whether the home base stations information database has covered this geographical position when accepting this detection instruction.Above-mentioned home base stations information database is meant: write down all or nearest base station and positional information thereof of serving for this user.(x, y), then base station A is written into (x, y) the checked base station code tabulation of needs if the service range through inspection mobile phone end discovery base station A has covered.If spent a period of time; User's mobile phone has been found a new base station B; It at first obtains geographical position and the overlay area of B and upgrades local base station information database through the network service so, and then the coverage of inspection base station B whether cover (x, y).If cover really, base station B also is written into (x, y) the checked base station code tabulation of needs so.
Because need more accesses network, the strategy that the target geographic position signal characteristic that the power consumption of this strategy is higher than directly to be provided according to server end detects, but it is still than directly calling the low in energy consumption many of GPS transducer.This strategy only is used for the situation that the signal characteristic database of server end can't the coverage goal geographical position; Along with server end signal characteristic database is more and more complete; This situation can be fewer and feweri, and the use of this strategy also reduces thereupon, finally carries out the transition to and uses optimal policy fully.
The other technologies characteristic is identical with embodiment 1.
