Description
Technical field
The present invention relates to wireless communication system, design especially and in wireless communication system, position the apparatus and method that algorithm is selected.
Background technology
Location technology in wireless communication system has multiple, and commonly used mainly contains three kinds:
(1) sectors/cells identifier (being designated hereinafter simply as CELL-ID)
The CELL-ID locate mode is the simplest a kind of locate mode, and it determines mobile subscriber's position according to destination mobile terminal cell ID of living in (CELL-ID).CELL-ID locate mode targeting scheme Network Based, its major advantage are to need not mobile network and portable terminal are made amendment, and are easy to realize; Good spreadability and reliability are arranged; Response time is short, and whole position fixing process only needs about 1 second.Its shortcoming is that positioning accuracy is relatively poor and depend on the size of base station coverage area, and general positioning accuracy is at hundreds of rice.In the less area of base station distribution, be difficult to obtain desirable positioning accuracy as suburb and rural area.
(2) time of advent poor (being designated hereinafter simply as TDOA)
The TDOA locate mode is by the propagation time difference of measurement target portable terminal transmitter arrival different base station receiver, rather than the definite time, determines the position of destination mobile terminal.In this locate mode, it is on the Hyperbolic Equation of focus that destination mobile terminal is positioned two base stations.Determine that the two-dimensional coordinate of destination mobile terminal need set up two Hyperbolic Equations (at least 3 base stations) at least, two hyperbola intersection points are the two-dimensional coordinate of destination mobile terminal.TDOA locate mode targeting scheme Network Based, its advantage are that positioning accuracy is higher, do not require the precise synchronization between portable terminal and the base station, are easy to realize that performance is superior relatively under imperfect environment; Shortcoming is in order to guarantee the timing accuracy of base station, to need to transform base station equipment.
(3) agps system (being designated hereinafter simply as A-GPS)
The GPS location is to position according to global positioning system (being designated hereinafter simply as GPS) satellite.The positioning accuracy height of GPS, but the response time is longer.After the GPS receiver started, very long even greater than 10 minutes to the search time of satellite, this was for some emergency application, and for example 119 to report to the police obviously be unacceptable.But can set up a GPS grid of reference that is connected with mobile radio communication, in order to response time and the raising positioning accuracy that shortens the GPS receiver.A-GPS is that mobile radio communication sends auxiliary positioning data such as the parameters such as difference correction data, satellite transit situation that the GPS grid of reference produced to travelling carriage, sends the apparent position of travelling carriage in the mobile network database or the position of base station cell to travelling carriage again.Travelling carriage according to its apparent position and current satellitosis, can in seconds capture the navigation signal of satellite after receiving above-mentioned information.The difference correction data that travelling carriage is also sent according to the GPS grid of reference are in order to proofread and correct locator data, and make A-GPS reach the highest setting accuracy: receive under the satellite-signal situation outdoor, the A-GPS setting accuracy is 5～30m.
In addition, also have other some location technologies,, be in test or conceptual phase at present as fingerprint location, the angle of arrival (the following AOA of abbreviating as), the time of advent (the following TOA that abbreviates as) etc., not extensive commercial, do not give unnecessary details one by one at this.
At present, Wimax positioning service (being designated hereinafter simply as LBS) network reference model is as shown in Figure 1 under the defined non-roaming state of Wimax forum (being designated hereinafter simply as Wimax forum) group of networks (being designated hereinafter simply as NGW).The network architecture of Wimax is assigned to from big functional areas, comprises three parts: travelling carriage (being designated hereinafter simply as MS), access business network ASN, connection business network CSN.Wherein, ASN comprises base station (being designated hereinafter simply as BS) and access business network gateway (being designated hereinafter simply as ASN GW).Interface between MS and the BS is commonly referred to as air interface, is the R1 interface in the Wimax network reference model; Interface between BS and the ASN GW is the R6 interface; Interface between CSN and the ASN GW is an Interface R3.In the Wimax LBS network reference model, the module relevant with LBS comprises under non-roaming state:
(1) location-server (Location Server is hereinafter to be referred as LS)
LS is a functional entity that is positioned on the CSN, and the pass between the positioning client terminal of outside is the relation of " client＜-〉 server ", and the function of authorization check is provided for the travelling carriage of the client of outside and location request.In addition, LS also can have the function of location Calculation.
(2) register control (Location Controller is designated hereinafter simply as LC)
LC is responsible for determining and reporting the positional information and the positional parameter of travelling carriage, LC can provide these positional informations and the positional parameter entity to LS, MS or other ASN inside, as RRM (being designated hereinafter simply as RRM) module and mobile management (being designated hereinafter simply as MM) module.In case receive the request from MS, LS or ASN internal module, the measurement that LC is relevant with triggered location is collected the location Calculation parameters needed and is carried out location Calculation.LC generally is positioned at the ASN network, if for the ASN that decomposes, then be positioned on the ASN GW.
(3) location agency (Location Agent is designated hereinafter simply as LA)
The major function of LA optionally also can be collected the parameter relevant with reporting the location and give LC for being carried out the relevant measurement in location.The function of LA can be positioned at BS, MS or the both has.If have the function of LA on the MS, corresponding BS also has the function of LA.
At this Wimax LBS network architecture, the defined processing messages end to end of the benchmark of Wimax forum (hereinafter referred to as baseline) manuscript flow process as shown in Figure 2.Its step is as follows:
201 MS or LBS client are initiated positioning service, can send locating request message to location-server LS by positioning client terminal or MS;
202 LS send authentication and authorization inspection request to authenticated/authorized/charging (being designated hereinafter simply as AAA) entity;
203 AAA carry out the authentication and authorization inspection;
204 AAA send authentication and authorization inspection response, return authentication and authorization check result to LS;
205 because CSN connects a plurality of ASN networks simultaneously, and LS need look for a service ASN at MS (the being designated hereinafter simply as target MS) place that is positioned, and transfers to the LC that is positioned at service ASN GW and handle;
206 find the service LC of target MS after, LS sends the positioning reporting request to service LS;
207 carry out the position deterministic process of ASN inside;
After 208 207 successful execution are finished, can obtain the positional information of target MS, LC reports this locating information to LS;
209 LS send location response message to Location Request side (MS or positioning client terminal), return the actual position information of target MS;
210 LS send metering data to accounting server and upgrade, the professional needed expense of this LBS of deduction from requestor's account, and this process is an optional process, for some particular request, as emergency services, Lawful Interception etc., do not need to pay, thereby do not need to carry out this step yet.

609 LS send location response message to Location Request side (MS or positioning client terminal), return the actual position information of target MS;
610 LS send metering data to accounting server and upgrade, the professional needed expense of this LBS of deduction from requestor's account, and this process is an optional process, for some particular request, as emergency services, Lawful Interception etc., do not need to pay, thereby do not need to carry out this step yet.
Target MS stationkeeping ability is kept at the selection course of location algorithm among the LC, and the signaling procedure of algorithm selection failure as shown in Figure 7.Specific implementation process is as follows:
701 MS or LBS client are initiated positioning service, can send locating request message to location-server LS by positioning client terminal or MS, wherein carry parameter L BS type of service, as automobile navigation or personnel tracking etc., after LS receives, parse the LBS type of service, and therefrom search LBS QoS mapping table, if can find, then turn to 701-1, otherwise, turn to the step 802 among Fig. 8;
701-1 LS searches the pairing LBS qos parameter of this LBS type of service from the LBS QoS mapping table shown in the table 1;
702 LS send authentication and authorization inspection request to authenticated/authorized/charging (being designated hereinafter simply as AAA) entity;
703 AAA carry out the authentication and authorization inspection;
704 AAA send authentication and authorization inspection response, return authentication and authorization check result to LS;
705 because CSN connects a plurality of ASN networks simultaneously, and LS need look for a service ASN at MS (the being designated hereinafter simply as target MS) place that is positioned, and transfers to the LC that is positioned at service ASN GW and handle;
706 for after MS finds service LC, and LS sends the positioning reporting request to service LS, comprising the LBS qos parameter of the LBS business of being asked;

● the property list of the different location algorithms shown in the table 3;
● target MS stationkeeping ability information;
● the LBS qos parameter of the LBS business of being asked;
But location algorithm is selected failure, as because target MS neither supports A-GPS, does not support location algorithms such as TDOA again, and sub-district ID mode can not satisfy the required precision of the positioning service of being asked etc. again.
708 LC report this locating information to LS, indication location failure, and to carry cause value be that location algorithm is selected failure;
709 LS send location response message to Location Request side (MS or positioning client terminal), the failure of indication location, and to carry cause value be that location algorithm is selected failure;
The signaling procedure that inquires LBS QoS when LBS type of service and LBS QoS mapping table are kept at PF as the measurement of operator as shown in Figure 8.Specific implementation process is as follows:
801 MS or LBS client are initiated positioning service, can send locating request message to location-server LS by positioning client terminal or MS, wherein carry parameter L BS type of service, as automobile navigation or personnel tracking etc., after LS receives, parse the LBS type of service, and therefrom search LBS QoS mapping table, if can find, then turn to 701-1, otherwise, turn to the step 802 among Fig. 8;
802 LS send authentication and authorization inspection request, the type of service of wherein carrying LBS to the AAA entity;
803 AAA carry out the authentication and authorization inspection;
804 AAA send LBS QoS query messages to PF, wherein carry the LBS type of service;
805 PF inquire the professional pairing LBS qos parameter of this LBS according to the LBS type of service from the LBS QoS mapping table shown in the table 1;
806 PF send LBS QoS response message to AAA, wherein carry the LBSQoS parameter of the LBS business of asking;
807 AAA send authentication and authorization to LS and check message, wherein carry the LBS qos parameter;
