Description
Technical field
The present invention relates to the communications field, in particular to a kind of method of auxiliary positioning acquisition of information, device and terminal.
Background technology
At present, location-based service has become one of the most frequently used service relied on most in people's daily life.In order to provide the location-based service of more high-quality to user, various location-based service technology is also arisen at the historic moment, as forward link localization method (AdvancedForwardLinkTrilateration, referred to as AFLT), CELLID (CellIdentity), digital (TimeDifferenceOfArrival, referred to as TDOA), senior time difference detection and location method (EnhancedObservedTimeDifference, referred to as EOTD), time of arrival differs from localization method (ObservedTimeDifferenceOfArrival, referred to as OTDOA), GPS (Global Position System) (GlobalNavigationSatelliteSystem, referred to as GNSS) etc.Above-mentioned location-based service technology has his own strong points, and locating speed and degree of accuracy weigh two important indicators of location technology quality, is also two the very important indexs affecting Consumer's Experience.
In above-mentioned various location-based service technology, GNSS location is the most accurate.
GNSS location needs first to catch GNSS satellite, download navigation text from the GNSS satellite captured again, then according to navigation message calculate GNSS satellite coordinate position and and equipment to be positioned between distance, when known four GNSS satellite coordinate and and equipment to be positioned between distance after, the three-dimensional coordinate position of equipment to be positioned and the clock correction with GNSS satellite can be calculated.When after the three-dimensional coordinate position calculating equipment to be positioned, by coordinate conversion and the known exact position of terminal to be positioned in the earth of combining geographic information system (GeographicInformationSystem, referred to as GIS) i.e..
Theoretically, the download of general minimum navigation message collection needs the time in 18 seconds.But in actual use, because satellite-signal is more weak, the motion causing equipment to be positioned to receive high, the to be positioned equipment of the navigation message bit error rate and Navsat causes navigation message to pass the reason of the many aspects such as auxiliary interruption, not good, the to be positioned terminal receiving ability difference of environment residing for equipment to be positioned, GNSS can be caused longer for positioning time, general more than one minute, even cannot locate.
The appearance of A-GNSS technology (AssistedGNSS) is just in order to solve the problem of GNSS length positioning time.A-GNSS is a kind of by network distally server acquisition navigation message or the alternative method downloaded from satellite such as prediction navigation message, location model etc.Due to by network distally server obtain the speed of navigation message far faster than the speed downloading navigation message from GNSS satellite, thus reach the object accelerating location.
There is following shortcoming in existing auxiliary positioning technology for information acquisition:
1, comparatively complicated.Different networks has different agreements, and for some network as TD-SCDMA, most assisted location service device exists compatibility issue.
2, success ratio is low.In laboratory environments, the success ratio of navigation message is about about 80%, and the success ratio of pretest navigation message then lower (mobile GSM about 33%, mobile TD-SCDMA50%, mobile TDD-LTE about 75%).May be lower in actual use procedure.
3, flow is consumed.Need activating data service distally server acquisition auxiliary positioning information.
4, pretest almanac data poor compatibility in different positioning equipment.
