Description
Technical field
The present invention relates to wireless communication technology, particularly a kind of localization method and equipment.
Background technology
Mobile location service is a business of utilizing the position of UE (User Equipment, subscriber equipment) to carry out, such as emergency relief etc.Current, can there be following two kinds of implementation methods the location: chain of command location and user's face location (Secure User-Plane Location).The chain of command location is meant that position fixing process need use RNC (Radio Network Controller, radio network controller), CN (Core Network, core net) signaling link between, concrete scheme is: CN sends Location Request triggered location process to RNC, RNC finishes behind the positioning action to CN restoring to normal position result, and CN, RNC, NodeB (base station), UE etc. will participate in the position fixing process; And under user's face locate mode, mobile communication equipment uses the IP link to communicate with location-server, existing mobile communications network infrastructure is remained unchanged, be that position fixing process is a PS (Packet Switched for RNC and Node B, packet switching) territory service access, all positioning control signalings and measurement data are directly mutual between the locating control center of core net and UE, and RNC mainly plays the effect of transmission bearer.
The present main method in the location of chain of command has CELL ID, CELL ID+TA+AOA, OTDOA, UTDOA, A-GNSS etc.
The localization method of user's face mainly contains CELL ID, A-GPS.
Below existing localization method is described.
1, based on the method for CELL ID:
In the method based on Cell ID (being cell coverage area), the position of UE is estimated according to the information of its service NodeB.The information of this service NodeB and sub-district can be obtained by calling, location area updating, cell update, URA (UTRAN Registration Area, UTRAN Acceditation Area) renewal or Routing Area Update.The locating information that covers based on Cell can be represented as the cell ID of sub-district, place, Service Area Identifier, or the relevant geographical coordinate of Serving cell.Its positioning accuracy depends on radius of society, and promptly hundreds of rice is to several kilometers.
2, the method for CELL ID+TA+AOA (cell ID+pre-set time+direction of arrival of signal angle):
NodeB obtains the AOA (Angle O fArrival, direction of arrival of signal angle) that UE transmits by smart antenna, and it is on the ray of starting point that UE is in Node B, and the angle that ray is rotated counterclockwise from direct north is AOA.
The RxTD that the base station reports (time of reception deviation) deducts the Tadv (pre-set time) that UE reports and multiply by the light velocity divided by 2, has represented UE with the distance between the Node B, and it is that the center of circle, distance are on the circumference of radius that UE just is in Node B.
RNC just can calculate the position of UE according to the geographical location information of above information and Node B.
The positioning accuracy of CELL ID+TA+AOA method is at 30-200 rice.
3, OTDOA (Observed Time Difference Of Arrival observes arriving the time difference) localization method:
In UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system), the OTDOA method is main according to " SFN-SFN observed time difference type 2 (SFN-SFN observed time difference types 2; SFN:system frame number, System Frame Number) " measurement result can be with reference to " First Path Type (first path type) ", " RSS on DwPTS (the RSS:Received Signal Strength received signal intensity of each sub-district; DwPTS:Downlink Pilot TimeSlot, descending pilot frequency time slot) " estimating user position and the measurement result of " UE Related Speed (UE relevant speed) ".These measurement results are in conjunction with the result of the actual drive test and the network planning, can be used for effective estimating user position.The certainty of measurement of this method depends on number, measuring period, certainty of measurement and the location-estimation algorithm that can measure the sub-district.And can there be the processing and the compensation method of the navigation system of non-direct reach path by some,, have kept according to the different channels situation and selected different estimators, obtain better location estimation result according to " the First Path Type " that measurement reports.
Such as at TD-SCDMA (Time Division Synchronous CDMA, time-division is synchronous--and code division multiple access inserts) in the system, it is by detecting definite UE position of time difference that two base station signals arrive, measuring amount is SFN-SFN Observed Time Difference, and this measurement is carried out by UE.Fig. 1 is an OTDOA positioning principle schematic diagram, and as shown in the figure, the OTDOA method is called hyperbolic fix again, and it is on the hyperbola of focus that UE is positioned at two base stations.Need set up plural Hyperbolic Equation owing to determine the UE position, two two-dimensional position coordinates that hyp intersection point is UE, therefore, the OTDOA method requires to have simultaneously the base station more than three to participate in the measurement of positional parameter.As shown in Figure 1.
The rudimentary algorithm principle of OTDOA:
Suppose the height of delocalization UE, the coordinate of supposing UE for (x, y), 3 base station signals of then minimum needs are received, the position coordinates of i base station transmitter be (xi, yi), i=1,2,3.The time difference of UE observation is respectively τ 1,2, τ 2,3, τ 1,3.The group of then solving an equation:
Can obtain UE coordinate (x, y).If it is correct that UE measures, and the influence that does not have multipath to disturb, there is redundant one in so above 3 equations, just 3 equations are 2 uncorrelated equations.
When equation had only one to separate, this was separated the coordinate that is UE and separates.
When equation has 2 to separate, use with less that of this cell base station distance and separate, another is separated abandon as separating at last.When equation does not have when separating, this time location survey is invalid.
The positioning accuracy of this method is probably at 10-200 rice.
4, U-TDOA (Uplink Time Difference of Arrival, up arrival time difference) localization method:
The U-TDOA localization method is by locating to measure the signal arrival time difference that sends signal UE, the position of calculating UE at Different L MU (Location Measurement Unit, location measurement unit).This method does not need to understand UE launch time and does not require that UE has any new function.The signal that arrives Different L MU owing to the UE upward signal is inconsistent, needs to adopt the method for intersection convolution to obtain signal arrival time difference accurately, and then accurate positioning UE.
The principle of U-TDOA localization method is consistent with the O-TDOA method, adopts hyperbola positioning method.
5, GPS (Global Positioning Systems, global positioning system) assisted location method:
Require UE that the GPS module is housed, assist the location.Its positioning accuracy is than higher, can reach in several meters the scope.
The deficiencies in the prior art are:
The localization method of user's face is fewer at present, do not have at UE under the situation of GPS module, the positioning accuracy of user's face can only depend on the radius of sub-district, and radius of society can reach several kilometers even tens kilometers, this precision can not satisfy the demand of positioning service, needs higher positioning accuracy such as emergency rescuing system.
In addition, if use the chain of command location, though can obtain high orientation precision.But the equipment that requires network all must be consistent on positioning function.Such as the centre of location is in RNC inside or in the RNC outside, be RNC be the center or SAS (the independently centre of location) for the center, whether support IUPC interface etc. all will carry out requirement.This just relates to the equipment development of all network equipment provider, and its exploitation is limited.This is difficult for operator.So merely rely on the position that the chain of command location can not guarantee can both in time obtain under all situations UE.And the result of chain of command location also is independent of professional, for some positioning services, still can't obtain the higher positioning service of positioning accuracy.
