Description

A kind of measurement processing method and apparatus of auxiliary observation difference time of advent location
Technical field
The present invention relates to mobile communication technology, particularly a kind of measurement processing method and apparatus of auxiliary observation difference time of advent location.
Background technology
Below to the principle of OTDOA (Observed Time Difference Of Arrival observes and arrives the time difference) localization method, and the mechanism of current existing measurement GAP (measurement clearance) is introduced.
1, the method for OTDOA:
At UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) in system, OTDOA method Main Basis " SFN-SFN observed time difference type 2 (SFN to SFN observed time difference type 2; SFN:system frame number, System Frame Number) " measurement result; can with reference to " First Path Type (the first footpath type) " of each community, " RSS on DwPTS (RSS:Received Signal Strength, received signal strength; DwPTS:Downlink Pilot TimeSlot, descending pilot frequency time slot) " and " UE Related Speed (UE relevant speed; UE:User Equipment, subscriber equipment) " measurement result, estimating user position.These measurement results, in conjunction with the result of actual drive test and the network planning, can be used for effective estimating user position.The certainty of measurement of the method depend on can measure community number, measuring period, certainty of measurement and location-estimation algorithm.And process and the compensation method of the navigation system of non-direct reach path can be there is by some, according to measuring " the FirstPath Type " that report, remaining and selecting different estimators according to different channels situation, obtaining better location estimation result.
Such as at TD-SCDMA (Time Division Synchronized Code Division MultipleAccess, Time division multiple access) in system, it determines UE position at the time difference arrived by detecting two base station signals, measuring amount is SFN-SFN Observed Time Difference, and this measurement is performed by UE.Fig. 1 is the location schematic diagram of UE on a hyperboloid, and as shown in the figure, OTDOA method is also called hyperbolic fix, and UE is positioned at on the hyperbola that is focus of two base stations.Owing to determining that UE position needs to set up plural Hyperbolic Equation, two hyp intersection points are the two-dimensional position coordinate of UE, and therefore, OTDOA method requires that the base station simultaneously having more than three participates in the measurement of positional parameter.
The rudimentary algorithm principle of OTDOA:
Suppose the height of delocalization terminal, suppose that the coordinate of terminal is for (x, y), then minimum needs 3 base station signals are received, and the position coordinates of i-th base station transmitter is (xi, yi), i=1, and 2,3.The time difference of terminal observation is respectively τ 1,2, τ 2,3, τ 1,3.Then solving equations
( x - x 2 ) 2 + ( y - y 2 ) 2 - ( x - x 1 ) 2 + ( y - y 1 ) 2 = τ 1,2 c ( x - x 3 ) 2 + ( y - y 3 ) 2 - ( x - x 1 ) 2 + ( y - y 1 ) 2 = τ 1,3 c ( x - x 3 ) 2 + ( y - y 3 ) 2 - ( x - x 2 ) 2 + ( y - y 2 ) 2 = τ 2,3 c
The coordinate (x, y) of terminal can be obtained.If it is correct that terminal is measured, and do not have the impact of multi-path jamming, there is of redundancy in so above 3 equations, namely 3 equations are 2 uncorrelated equations.
When equation only has one to separate, this solution is the coordinate solution of UE.
Use when equation has 2 to separate and separates conduct with this cell base station distance less that and finally separate, another solution is abandoned.When equation is without solution, this time location survey is invalid.
The positioning precision of the method is probably at 10-200 rice.
In LTE (Long Term Evolution, Long Term Evolution), the party's ratio juris is similar.The amount just measured is reference signal time difference (Reference Signal Time Difference is called for short RSTD), and its implication is the time difference of the reference signal of the Liang Ge community received.Similar with the SFN-SFN OTD type2 in UMTS system.Using method in location is also similar.
In LTE system, the positioning flow of OTDOA is generally as follows:
1.E-SMLC (Evolution-Serving Mobile Location Centre, evolved Serving Mobile Location Center) by LPPa (LTE Positioning Protocol Annex, LTE location protocol annex) agreement obtains the OTDOA supplementary of community this eNB from eNB (evolution base station), comprising the configuration information etc. of the PRS (positioning reference signal, location reference signals) of each community.
2., when terminal needs to carry out OTDOA location, E-SMLC provides auxiliary data to terminal, namely configures and measures cell set to locating terminal OTDOA, wherein provide the PRS relevant configuration information of community.
3. the auxiliary data that terminal provides according to E-SMLC is measured, and measures the RSTD of each OTDOA community, and measurement result is reported E-SMLC by LPP (LTE Positioning Protocol, LTE location protocol) agreement.
4.E-SMLC calculates the position of this terminal according to the result that terminal is measured.
PRS configuration information:
ENB reports E-SMLC by LPPa, and the E-SMLC information that is supplied to the community of UE can provide the configuration information of PRS, the configuration index number of instruction PRS.The configuration of concrete correspondence can with reference to following table:

Embodiment
Inventor notices in invention process:
In LTE system, the method for observed time difference (OTDOA) can be used to position.The associated ancillary information of OTDOA is sent to terminal by LPP agreement by location-server (E-SMLC), comprising the cell set can carrying out the measurement of OTDOA.Cell set includes co-frequency cell and alien-frequency district.Because the wireless capability of terminal is different, for alien-frequency district, if the relevant measurement of OTDOA will be carried out, base station is needed to be this locating terminal allocating and measuring GAP, so that locating terminal carries out the measurement of alien-frequency district during GAP.
But directly configured to terminal by E-SMLC because OTDOA locates the community of measurement of correlation, base station does not also know which community is terminal will measure, thus base station cannot allocating and measuring GAP to terminal.Terminal does not just have the suitable time to monitor the PRS signal of alien-frequency district, thus carries out the measurement of the RSTD of corresponding alien-frequency district.
Further, the cycle of PRS is 160ms, 320ms, 640ms and 1280ms, and particular location is the continuous several descending sub frame in the cycle.And normal measuring period is 40ms and 80ms, concrete GAP position is that one of them subframe starts continuous 6ms.If adopt normal measuring period, likely it is measured in GAP and forever all cannot receive PRS signal.And different communities, PRS may be different, and terminal also can be caused to be difficult to measure the PRS signal of all OTDOA communities.
Also be, because base station cannot know that terminal needs to carry out different-frequency measure at present, so terminal is not the measurement GAP that can obtain base station configuration, also just makes terminal not have the suitable time to monitor the PRS signal of alien-frequency district, thus the measurement of the RSTD of corresponding alien-frequency district can not be carried out.
Given this, in order to make locating terminal carry out the measurement of OTDOA alien-frequency district, several scheme will be provided in the embodiment of the present invention and make base station can reasonably measure GAP for terminal distribution, carry out the relevant measurement of OTDOA in order to accessory terminal.Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
