Description
Technical field
The present invention relates to communication technical field, particularly relates to a kind of method and apparatus of positioning terminal.
Background technology
Recently as the fast development of cellular mobile communication technology, the location technology based on cellular base station information is also gradual
Tend to be ripe, start to be paid close attention to by more people.The rise at full speed of domestic Internet of Things industry and the extensive popularization of 3G network, make
Broader prospect will be possessed by obtaining architecture technology, and it has become one of important value-added service now, can bring
While huge commercial value, additionally it is possible to provide service for personal and enterprise well, specifically include：Based on positional information
Inquiry and issue, navigation and the relief of physical disabilities, vehicle scheduling, traffic administration, antitheft etc..
At present more typically, and using commonplace base station positioning method include：
1. rise area's positioning (Cell of Origin, COO), it is mainly determined according to the domain identifier where mobile terminal
Coordinate position.The positioning precision of this method depends on the size of base station coverage area, and therefore, COO positioning is most simple, is easiest to reality
It is existing, but error is also maximum, typically more than 200 meters.
2. incidence angle positions (Arrival of Angle, AOA), receiving aerial array by base station measures mobile platform hair
The incidence angle of radio wave, using two incidence angles, the position of tested mobile station is determined in intersection, suitable for line-of-sight propagation situation,
It is higher to equipment requirement.
3. arrival time positions (Time ofArrival) and reaching time-difference positioning (Time Difference
OfArrival, TDOA) using mobile terminal signal reach multiple ground base stations temporal characteristics amount calculate pseudorange value, and by
The method of Distance Intersection carries out positioning calculation.Wherein TOA is directly obtained using transmission time characteristic quantity of the signal from base station to user
To pseudorange value, sphere intersection equation is established using base station location and pseudorange value, solution obtains the position of user；TDOA is then using more
Time difference characteristic quantity between section pseudorange, equation solution is intersected by hyperboloid.
It is a kind of base station and the united localization method of satellite system 4. hybrid positioning technology, including A-GPS
And A-MPS (Assisted Mobile Position System) (AssistedGPS).
5. the localization method based on location fingerprint (LF).
Location fingerprint location algorithm was proposed by Microsoft research institute in 2000 earliest.Its core concept is similar to employee
Fingerprint is checked card：Fingerprint is the pattern that can accurately identify a personal identification, before certain worker is identified for the first time, is needed prior
Fingerprint and worker are gathered, the correlation database of fingerprint and identity is formed, when employee's working fingerprint is checked card, is matched according to AD HOC
Fingerprint, you can determine worker.
And the radio wave of Base Transmitter produces close with its surrounding environment by reflection, refraction and diffraction in each position
The multipath signal that cut is closed, for a certain ad-hoc location, the position has unique channel multipara structure, such multipath
Signal is referred to as " fingerprint " of the position.Location fingerprint location algorithm is exactly the characteristic parameter for extracting multipath signal, then should
The finger print data that parameter is previously stored in fingerprint database is matched according to correlation matching algorithm, finds out most similar one
Group or several groups of data, obtain positioning result.
The matching algorithm of generally use is KNN (K Nearest Neighbour) algorithm, and its principle is that positioning terminal is connecing
After receiving base station relevant information, it is ranked up according to the ascending all fingerprints in fingerprint database of Euclidean distance, preferably
Most like preceding K fingerprint, then carry out the calculating of final positioning result.
The most significant feature of fingerprint location technology is that positioning measurement special module need not be added in existing terminal, economical
Cost is low, and software aspects are easily achieved, and localization method is simple, is widely used.Therefore as at present towards the public development and
The main flow direction of application.
When carrying out architecture, because part storage terminal is only capable of reporting the information for the single base station being currently located, fingerprint
Characteristic information it is less, therefore in actual applications, simplified fingerprint algorithm can only be employed, i.e., single base station centroid algorithm.It is existing
The single base station algorithm having is applied to be only capable of reporting the terminal for being currently located cell (Serving Node), can be for those simultaneously
The terminal for being currently located cell and information of adjacent cells is reported, then it is fixed to be lifted to make full use of the information of adjacent cells wherein included
Position precision.
With the fast development of future chips and hardware, the end for being currently located cell and information of adjacent cells can be reported simultaneously
End will be more and more, if insufficient in architecture algorithm utilize information of adjacent cells, this will be nothing to terminal capability
Shape wastes.
