Description
Technical field
The present invention relates to the location technology of mobile communication, relate in particular to based on network hybrid locating method in a kind of WCDMA system.
Background technology
In the positioning service standard 3GPP of Wideband Code Division Multiple Access (WCDMA) (WCDMA) system TS 25.305, have two kinds of locate modes: based on network locate mode and based on the locate mode of travelling carriage, both topmost difference are to position calculating wherein.If carry out final location Calculation, then be based on the locate mode of travelling carriage at travelling carriage; If final location Calculation is to be finished by the mobile position estimation center (SMLC) that is arranged in radio network controller (RNC), then is based on network locate mode.Wherein, in based on network locate mode, following three major types standard setting method is arranged: based on network property of network auxiliary global satellite fix (A-GPS) method, based on network observed time difference (OTDOA) localization method and based on network center of housing estate (CELLID) localization method.Wherein, the something in common of A-GPS, OTDOA method is: all to carry out necessary location survey before the location, as: the location survey location survey relevant that A-GPS is relevant with OTDOA.
According to shown in Figure 1, when carrying out based on network A-GPS location, at first, SMLC waits for that to the location survey request of subscriber equipment (UE) transmission A-GPS type UE returns corresponding positioning measurement result; If UE does not report the positioning measurement result of the type within preset time, then SMLC is provided with based on network A-GPS localization process for failing, and withdraw from A-GPS localization process flow process, otherwise just proceed following position fixing process: if in the positioning measurement result that SMLC receives, the pseudorange measurement that comprises four or four above effective GPS satellites, then SMLC utilizes the measurement result of being received to finish the location, and current localization process success is set, and finishes the localization process flow process; If only comprise the pseudorange measurement of three effective GPS satellites in the measurement result, and SMLC can obtain the average height of sub-district, UE to be positioned place, then SMLC utilizes the measurement result of being received to finish the A-GPS location of height supplementary mode, and current localization process success is set; Except that above-mentioned two kinds of situations, the measurement result of returning all can't be finished based on network A-GPS localization process for SMLC, promptly represents this localization process failure.
As shown in Figure 2, when carrying out based on network OTDOA location, at first, SMLC sends the location survey request of based on network OTDOA type 2 to UE, and then, SMLC waits for that UE returns corresponding positioning measurement result.Simultaneously, when the number of the current active set cell of UE to be positioned was non-vanishing, then SMLC sent (RTT) special measurement request two-way time to the sub-district that these are in the active set; If at the fixed time, UE does not return the positioning measurement result of OTDOA type 2, then SMLC just is provided with current localization process for failing, and end OTDOA localization process flow process, otherwise can finish based on network OTDOA location in both cases: if in the positioning measurement result that SMLC receives, comprise the adjacent sub-district OTDOA measurement result within two or more agreement prescribed limits, then SMLC utilizes measurement result received and several RTT measurement results of having received to finish the OTDOA location, and based on network OTDOA localization process is set is successfully; Perhaps, if in the positioning measurement result that SMLC receives, at least the RTT measurement result that comprises a sub-district, and UE has also returned UE transmitting-receiving (UE Rx-Tx) time difference type 2 positioning measurement result of the respective cell within the agreement prescribed limit, then SMLC can finish the time of advent location estimation of (TOA) mode, and based on network OTDOA localization process is set is successfully; Except that above-mentioned two kinds of situations, the measurement result of returning all can't be finished based on network OTDOA localization process for SMLC, promptly represents this localization process failure.
When carrying out based on network CELLID location, SMLC covers according to the position of UE Current Serving BTS and sub-district and locatees.If the sub-district is an omni cell, then the position of UE is to be the center with the serving BS, and radius is in the circle of coverage radius of cell; If the sub-district divides the sector, can determine further that then UE is in the scope that certain sector covers.In brief, SMLC is with the geometric center position of sub-district, the present place of the UE final position estimated result as this UE.
The characteristics of above-mentioned various localization methods are:
The positioning accuracy of based on network A-GPS localization method is the highest, but the location response time is the longest.In open environment, as outskirts of a town or rural area, multipath and to block be negligible, the positioning accuracy of A-GPS can reach about 10m even be more excellent; If UE is in urban area circumstance, do not have block and multipath not serious, positioning accuracy will be about 30～70m; If UE is in zone indoor or other multipath and serious shielding, this moment UE enough satellite-signals that defies capture, A-GPS can't finish the location, this is its major limitation.The response time of A-GPS localization method is long slightly, and under the cold start-up situation, the location response time of A-GPS is 10s～30s; Under the normal operating conditions, the response time is about 3～10s.
The positioning accuracy of based on network OTDOA localization method is taken second place, and the location response time is moderate.Because the WCDMA wireless network signal covers wide, the occasion that some can't position with A-GPS then can be finished the location with OTDOA, as indoor environment.But cover inadequate occasion at the WCDMA wireless network signal, the positioning accuracy of OTDOA method will have bigger decline.Use this method, UE can be positioned in 10～20 meters scopes in suburb and rural area; Because high-lager building is more, and radio propagation environment is bad, signal is difficult to directly arrive from the base station UE in the city, generally will be through superrefraction or reflection, error has also just appearred in the TOA of down-bound pilot frequency signal, so positioning accuracy can be affected, and orientation range is about 100～200 meters.The location response time of OTDOA is about 3～6s generally speaking.
The positioning accuracy of based on network CELLID localization method is minimum, and the location response time is the shortest.This method need not to carry out any location survey, directly with the geometric center of sub-district, UE to be positioned place as positioning result.Obviously, the precision of this localization method depends on the size of UE sub-district of living in fully: kilometer do not wait from hundreds of rice to tens.In the rural area, the coverage of sub-district is very big, so the positioning accuracy of CELLID is very poor.And the cell coverage area of urban area circumstance is less, and general radius of society is 1～2km; For the city of prosperity, might adopt microcellulor, radius of society may arrive hundreds of rice, and the positioning accuracy of CELLID will correspondingly rise to hundreds of rice this moment.Because the CELLID location does not need UF to position measurement, so the location response time is shorter, generally in 3s.
A large amount of positioning experiment results show, only use any in the said method, all can't guarantee all can satisfy in any case the required precision of FCC (FCC) regulation: the precision of positioning service will reach in 150 meters under 95% the situation reaching under 67% the situation in 50 meters.Therefore, must use based on network hybrid locating method, promptly comprehensively use the multiple standards localization method, can guarantee under any circumstance all can obtain gratifying positioning accuracy.
When using existing based on network hybrid locating method, SMLC issues a plurality of location surveys simultaneously, comprising: based on network A-GPS type location survey, based on network OTDOA type 2 location surveys (and RTT location survey of relevant Active Set sub-district).After obtaining above-mentioned whole positioning measurement result, SMLC therefrom selects the positioning measurement result of certain class success to position calculating again; If all less than success, then SMLC will utilize the combination of above-mentioned positioning measurement result to carry out location estimation in all kinds of measurements.
The shortcoming of existing mixed positioning scheme is:
1, SMLC needs to send many location survey control informations at the Uu interface simultaneously.This not only can increase the signaling traffic load of Uu interface, and can improve the complexity that receives the handling positioning measurement control messages.In addition, in the WCDMA system, for same message, the multipotency of Uu interface issues four transaction identification (Transaction ID) simultaneously, and the miscellaneous service mould is determined, as: power control, switching etc., only behind the Transaction ID that applies for Uu measurement control messages, just can start working, because SMLC takies a plurality of Transaction ID of Uu interface simultaneously, very easy other business module that causes is because of applying for that Transaction ID is forced to block.
2, SMLC only after receiving all positioning measurement result, just can carry out location estimation, so the average response time of its location is longer.
3, SMLC need safeguard the state of all kinds of location surveys simultaneously, comprising: measure and to wait for, to measure successfully, measures failure, measure control fail, measurement is overtime and measurement repeating transmission or the like.Because there is very big difference the response time of all kinds of location surveys, therefore to safeguard above-mentioned all kinds of state, complexity is very big.
4, SMLC need comprehensively use all kinds of measurement results to position calculating under the unsuccessful situation of all kinds of measurements.Because this moment, the quality of all kinds of measurement results was all lower, so the mixed positioning precision is not high.But this has but spent the SMLC long time and has positioned calculating, and is used for realizing simultaneously that the software and hardware of multiple location is also extremely complicated.
