Embodiment

At present, location technology commonly used mainly contains three kinds in cellular mobile communications networks:

(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 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.

The present invention is based on CELL ID, TDOA and A-GPS commonly used at present, design Wimax network kind signaling process process and interface message, to guarantee each entity or functional module collaborative work in the Wimax network, for the user provides positioning service, and wherein interface message and flow process standardization, to guarantee the interconnection and interflow between the devices from different manufacturers.

The Wimax network of this patent invention provides the method for LBS business to comprise:

1. the processing method of positional information is provided based on the Wimax network of CELL ID

This processing procedure comes to provide LBS business for the user according to the location technology of CELL ID.LS sends Location Request from Interface R3 to the LC that is positioned at Wimax ASN GW, indication ASN provides the positional information based on CELL ID, after LC finds the present CELL ID of target MS, the information of plot planning during according to network design, corresponding C ELL ID is mapped as the geographical location information of this sector reality, and returns to LS.According to the residing state difference of MS, this processing procedure is divided into following two processes again:

● what MS was in idle condition (the following IDLE of abbreviating as) provides the processing method of positional information based on the Wimax network of CELL ID

When MS is in the IDLE state, when paging group (is called Paging Group in the standard, the following PG that abbreviates as, a general PG comprises several sub-districts) when changing, MS just carries out the position to network to be upgraded, so MS is in the IDLE state and is, the Wimax network can only know which PG MS is among at present, can not know definitely which sub-district MS is in.Thereby in this case, locate this MS if desired, and need carry out paging (being called Paging in the standard) to this MS, trigger this MS and withdraw from the IDLE pattern or carry out the position renewal, so that network obtains the cell information of this MS.Then, corresponding C ELL ID is mapped as the positional information of this sector reality, and returns to LS.

● MS is in the connection/state (the following Awake of abbreviating as) of waking up provides the processing method of positional information based on the Wimax network of CELL ID

When MS is under the Awake, set up and being connected of Wimax network, thereby the CELL ID. that network has been known this MS then, corresponding C ELL ID is mapped as the positional information of this sector reality, and returns to LS.

3. the processing method of positional information is provided based on the Wimax network of A-GPS

LS sends Location Request from Interface R3 to the LC that is positioned at Wimax ASN GW, and indication ASN provides the positional information based on A-GPS, and after LC received, the serving BS broadcasts to the MS place sent LBS measurement request, starts the measurement that GPS receives and is correlated with to trigger MS.Entity difference according to executing location is calculated can be divided into following two kinds of methods again:

● the Wimax network based on A-GPS that MS calculates provides the processing method MS of positional information to start GPS and receives, and calculates the positional information of MS according to the result that GPS measures, and then this positional information is sent to LC by LA, and LC reports to LS again.Because GPS receives and measure original just very power consumption, adding also needs to carry out position calculation, and this just further increases the weight of the burden of MS, thereby the very power consumption of this processing method.

● what LC calculated provides the processing method of positional information based on the Wimax network of A-GPS

MS starts GPS and receives, and MS does not calculate, and just the relevant measurement result of GPS is reported to LC by LA, is calculated by LC, and LC returns to LS to the positional information that calculates after calculating and finishing again.Owing to position calculation is transferred to network brings in execution, so just alleviated the burden of MS power consumption to a certain extent.
