Description
Technical field
The present invention relates to (the Time Division-Synchronous Code Division Multiple Access of TD-SCDMA in the wireless communication technology field; The TD SDMA access) user interface positioning method of system; And particularly, relate to a kind of user plane reinforced cell localization method.
Background technology
In recent years, the mobile communication technology development was swift and violent, and particularly digital mobile cellular telecommunication is particularly outstanding.International Telecommunications Union is trying hard to recommend the 3G (Third Generation) Moblie standard; Comprise TD-S CDMA, WCDMA (Wideband Code Division Multiple Access; WCDMA) and CDMA 2000, digital mobile cellular telecommunication possesses wide application prospect because of its unique advantage.
Mobile location service is a business of utilizing the position of subscriber equipment (UE) to carry out; Become a kind of characteristic value-added service on the mobile network; Commercial value is very big; It is very abundant to use kind, makes it extremely attract people's attention in the 3G field owing to the raising of positioning accuracy and the employing of opening architecture, and being considered to possibly be one of representative applications of 3G.
Mobile positioning technique is that the requirement of network based consumer positioning selects specific localization method to obtain the technology of UE positional information.Through location technology, the user can realize following function: safe emergency is called out positioning service; Follow the tracks of the location of relevant criminal activity; Individual's positioning service (the for example inquiry of service industry such as traffic, lodging information); Intelligent transportation transportation location; The design of Radio Network System and resource management; Be used for the charging (confirming the communication cost of some position according to calling rate) of Radio Network System etc.
Usually, can there be following two kinds of implementation methods the location: chain of command location and user plane location.Chain of command location is meant that position fixing process need use wireless and dedicated signaling path core net, i.e. RNC (Radio Network Controller, radio network controller), and Node B will participate in the positioning control signaling process in the position fixing process; And under the user plane locate mode; Mobile communication equipment uses the IP link to communicate with location-server; Existing mobile communications network infrastructure is remained unchanged, and promptly position fixing process is a PS territory service access for RNC and Node B, and all positioning control signalings and measurement data are directly mutual between the locating control center of core net and UE; RNC mainly plays the effect of transmission bearer, and does not participate in the detailed process of location Calculation.
In the TD-SCDMA system; Localization method mainly contains three kinds: based on Cell ID (Cell identity; Cell ID) cell positioning method, OTDOA (Observed Time Difference Of Arrival; Arrive observed time difference) method and AGPS (Assisted Global Positioning System, agps system) method.
Based on the localization method of Cell ID is to utilize the coverage of sub-district to describe the geographical position of UE, and precision is very low, according to the different UE geographical position scopes that can confirm of cell coverage area also difference.Generally speaking, adopting such localization method locating accuracy scope is 100m～20km.
The OTDOA location can provide the positioning accuracy higher than cell localization; Its positioning accuracy can reach 50m～500m; But because the OTDOA location needs at least three base stations to be measured and could be realized; Therefore under the situation that base station distribution quantity is few in some network area, can't adopt the OTDOA method to realize the location.
The enhanced cell localization is on the basis of cell localization, increases other measurement means, is a kind of localization method higher than cell localization precision, can solve simultaneously the OTDOA location and can't realize the situation of locating in some cases.The cell localization that strengthens comprises AOA (Angle OfArrival; Arrive angle) location and Cell ID+TA (Time Advance; Timing Advance) location, these two kinds of location can be easy to realize under the chain of command locate mode, this be because; RNC (Radio Network Controller; Radio network controller) can initiate Iub mouth special measuring controlling message, with the be correlated with AOA information measurement of UE of request Node B, the position that promptly can confirm UE according to the geographical position and the AOA information of base station.Equally, Cell ID+TA mode also is easy to realize under the chain of command mode, this be because; RNC sends Uu mouth measurement control message request UE to carry out TA and measures, and is uploaded to RNC after UE measures, and RNC is through be correlated with RTD (the Rx Time Deviation of UE of Iub mouth special measuring controlling message request Node B; Time of reception is poor) measure; After RNC receives measurement report,, promptly can calculate the position of UE in conjunction with the Node B geographical position of sub-district and TA, RTD.
Yet regrettably, the cell positioning method of enhancing adopts the technology of user plane location can't realize that at present its main cause is; UE can't obtain AOA measured value and RTD measured value; And can only obtain the TA measured value, but when having only the TA measured value, positioning accuracy can reduce.
