Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to mobile terminal locating method, device and portable terminal that a kind of WIFI location and CELLID location combine.
Background technology
Along with developing rapidly of mobile communication technology, location-based service (LBS, Location Based Service) more and more receives people's concern, LBS is quite general in the application of the aspects such as intelligent transportation, emergency relief, Workflow Management, property monitoring, is exactly mobile positioning technique and the basis of these LBS services is provided.
At present, mobile positioning technique can be divided into satellite-based location technology, based on the location technology of wifi and the location technology of movement-based cellular network (Cellid).
Wherein, satellite-based location technology mainly contains GPS, GLONASS and the Big Dipper etc.The basic principle of GPS location is as known calculated data the position at the instantaneous place of satellite of high-speed motion, the position that the method for employing space length resection is calculated tested point, it requires the GPS receiver at a time to receive 4 and above gps satellite signal.The GPS location technology has the high characteristics of positioning accuracy, but it is only suitable for positioning in outdoor open environment, is difficult to realize the location owing to satellite-signal blocks in indoor and built-up urban environment.
The principle of wifi location is: the wifi hotspot location is more fixing, generally seldom change, if what one is particularly good at is known first the latitude and longitude coordinates of each wifi focus, just can according to mobile terminal to search to the wifi hot information inquire about latitude and longitude coordinates corresponding to this focus, and then realize the location.It is fast that Wifi location has locating speed, and positioning accuracy is high, is highly suitable for the characteristics that population, place that housing-group is more intensive position.But its shortcoming is: sometimes have the artificial situation of moving the wifi position (wireless router being moved to another place from a place such as removal of home), at this moment, if rely on merely the wifi location just may cause the wrong situation in location.
The Cellid positioning principle is similar with the wifi positioning principle, location-server is the latitude and longitude information of each base station of storage in advance, portable terminal is to the location-server request position information time, can current search to base station information send to location-server, location-server just can inquire latitude and longitude coordinates corresponding to this base station according to the base station information of receiving, and this latitude and longitude coordinates returned to portable terminal as the position at the current place of portable terminal, portable terminal has just been realized the location like this.Although the Cellid locating speed is fast, its positioning accuracy is very low, is difficult to satisfy the demand of hi-Fix.
Usually for the user, what at first consider is the correctness of position location, next is the precision of location, if at outdoor opening, GPS is user's first-selected locate mode naturally, if but at the indoor or built-up environment that is not suitable for the GPS location, then will consider to use wifi or Cellid to position.And use separately the wifi location, if the wifi position just might be occurred locating wrong situation by the people for moving (such as removal of home), this is unacceptable to the user; If use separately Cellid location, because base station location can not moved easily, so the position location do not have large mistake, but positioning accuracy is lower.
