Background technology
Location service (Location Based Service, referred to as LBS) refer to that mobile network obtains the positional information of mobile terminal by specific location technology, thereby for a kind of value-added service that terminal user provides Additional Services, can be widely used in all many-sides such as emergency relief, navigation tracking, transportation dispatching, mobile yellow pages.
In recent years, along with the increase of user's request, mobile positioning technique receives increasing concern, particularly 3G, and the increasingly mature development for mobile positioning technique of 4G technology provides support.In the network of 2G or 2.5G, owing to being subject to the restriction of network transfer speeds, GPS (the Assisted Global Positioning System of hi-Fix technology---network assistance, referred to as A-GPS) application limited to, and 3G, 4G network can provide high-speed radio download function, and this is just for mobile location service provides more wide development space.
A-GPS(Assisted Global Positioning System) be the GPS of network assistance, this method needs network and mobile terminal can both receive GPS information, be a kind of technology that network base station information and GPS information position mobile terminal that combines, can in 2G and 3G network, use.The advantage of this technology is mainly in its positioning precision, and in the open space such as outdoor, under normal operation circumstances, its precision can reach 5～10m, can be rated as a kind of location technology that current positioning precision is the highest.On the other hand, utilize the supplementary that network transmits can strengthen primary positioning time (Time To First Fix, referred to as TTFF), its time of catching first gps signal reduces greatly, generally only need several seconds, and may need 2～3 minutes (min) unlike the capture time first of GPS (Global Position System, referred to as GPS).The A-GPS location response time is between 3～10 seconds (s).
As the high-precision mobile positioning technique of one, A-GPS obtains the positional information of mobile terminal jointly by mobile terminal and GPS auxiliary positioning information, thereby need in mobile terminal, increase A-GPS receiver module (or external A-GPS receiver), to on network, add equipment such as building location server, reference receiver simultaneously.
The positioning flow of A-GPS is as follows:
(1) first mobile terminal arrives location server by the address, base station of itself by Internet Transmission.
(2) location server for example, according to the Position Approximate transmission satellite assistance data relevant to this position of this terminal: GPS ephemeris etc.
(3) utilize these information, the A-GPS module of terminal can be caught satellite very soon, to promote (the being also TTFF) ability the first locking time of gps signal, and receive GPS original signal, after restituted signal, computing terminal is to the pseudorange of satellite, and wherein, pseudorange is exactly the distance that is subject to various GPS error effects.
(4) terminal completes the calculating to exact position according to GPS pseudorange and the gps satellite supplementary measured.
It should be noted that the satellite assistance data in whole scheme is provided by reference receiver.Reference receiver obtains reference data (for example, clock, ephemeris, available constellation, reference position etc.) from satellite in real time, offers location server by network.In the time that mobile terminal needs satellite data, location server provides A-GPS auxiliary data by wireless network to terminal, to strengthen its TTTF, thereby greatly improves the sensitivity of A-GPS receiver module.
