Description
[technical field]
The present invention relates to a kind of method and system that is used for utilizing information estimated position two-way time, more specifically to being used to utilize two-way time information accurately to estimate the method and system of the position of portable terminal at mobile communications network.
[background technology]
The algorithm and the detailed method of the position in many tracing mobile commutation networks have now been developed.
Qualcomm has proposed to be used for the gpsOne (snapshot tracking) of synchronization CDMA network.Proposed the OTDOA method for the asynchronous WCDMA network, the A-GPA method is utilized the method for sub-district ID and is utilized the method for two-way time (RTT).
At this, can be called as RTD (round-trip delay) in the synchronization CDMA network and the RTT (two-way time) in the asynchronous WCDMA network two-way time.
GpsOne mainly adopts the gps measurement data of being measured and offered system by portable terminal, PN phase place, sub-district ID and RTD.
In the situation of GPS (global positioning system) method, AFLT (advanced forward link trilateration) method, mixed method, according to the defined message of standard (standard: 3GPP2C.S0022-Av1.0), based on the measured data of portable terminal and the estimated position.
But, in the situation of sector round-trip delay (safety net), the internal information of using system (particularly base station), standard or use method clearly by standard definition.
In addition, though developed the project of only using the sector round-trip delay, current technology does not also reach the actual realization and the application of sector round-trip delay.
Simultaneously, for a kind of location estimation method, the gps measurement data by utilizing portable terminal is the estimated position most accurately.But portable terminal must be limited in being positioned at the scope that can receive the satellite gps signal.
In passing through the example of pseudo noise phase estimation position, owing to only provide service by having a head that is in the portable terminal of trafficwise, so it provides one with reference to pseudo noise (RefPN) itself.This makes and must guarantee that the PN phase place that is used for the estimated position becomes difficult.
As the information that produces in the receiving demodulation unit in the base station two-way time information example in, can extract this information by the portable terminal that is in the trafficwise with a head.Therefore, the portable terminal that is arranged in the zone that can not carry out GPS service or only carries out service by a head can utilize the information of coming and going to estimate position more accurately.
But,, determine that as yet the device of the position of estimation portable terminal can receive the standard of information two-way time for current mobile communications network.Therefore, traditional position estimation device is that sub-district id information, gps measurement data, the PN phase information of utilizing the base station to provide come the estimated position.This causes producing a large amount of mistakes.
Simultaneously, method, OTDOA method and the A-GPS method of provide the method for using sub-district ID, using sub-district ID and RTT is used for the algorithm and the detail location method of estimation of WCDMA network.
Be difficult to realize making the OTDOA method not be used gradually.Therefore, WCDMA can adopt the mixed method of method, A-GPS method and its combination of using sub-district ID.
The A-GPS method is used the measured gps measurement data of portable terminal.Though the A-GPS method can be estimated position the most accurately, terminal must be limited in the scope that can receive the satellite gps signal that is positioned at.
Equally, only use sub-district ID to make estimated position very inaccurate.In order to remedy this inaccurate estimation, can use two-way time.
Can be by being in information two-way time that receiving demodulation unit that the portable terminal with a head in the trafficwise extracts the base station is produced.
Therefore, be positioned at zone that can not receive the GPS service or the portable terminal of only carrying out service, can utilize to estimate two-way time than only using sub-district ID more accurate location by a head.
Fig. 1 for example understands the structure of position estimating system according to prior art.
With reference to figure 1, existing location estimation method is divided into through first method of the mobile switching centre 500 that carries out voice service and process carries out second method at the packet data exchanged center 600 of data, services.
Find out the position of portable terminal by the log-in command of solicit operation or paging operation through first method of mobile switching centre 500.
Fig. 2 is the flow chart according to prior art, for example understands the position estimation procedure of utilizing mobile switching centre.
With reference to figure 2, if position estimation device 700 is asked positions to mobile switching centre 500 in the step of S200 representative, then mobile switching centre 500 sends the location registration request command messages to base station controller 400 in the step of S210 representative.
Then, base station controller 400 sends the location update request message of portable terminal 100 to mobile switching centre 500 in the step of 240 representatives.Mobile switching centre 500 sends the response message of location update request message to base station controller 400 in the step of S250 representative.
By the location information service that said method calculated, be mainly used in the service that does not require high-grade accuracy.
Simultaneously, search for the position of portable terminal 100 based on portable terminal 100 measured message through second method at packet data exchanged center 600.
Fig. 3 is the flow chart according to prior art, for example understands the position estimation procedure of utilizing the packet data exchanged center.
With reference to figure 3, portable terminal 100 sends initializing signal to base station controller 400 in the step of S300 representative, and base station controller 400 is asked connection managements to mobile switching centre 500 in the step of S310 representative.
Afterwards, mobile switching centre 500 asks channel allocation to base station controller 400 in the step of S320 representative.Therefore, traffic channel between base station controller 400 and the portable terminal 100 is set in the step of S330 representative.
After traffic channel is set, the packet data service channel (A11 setting) between base station controller 400 and the packet data exchanged center 600 is set in the step of S340 representative.
Then, portable terminal 100 will be used for the information of the location estimation of portable terminal, and for example gps measurement data and sub-district ID send to position estimation device 700, and install 700 and in the step of S350 representative estimated positional information is offered portable terminal 100.
Fig. 3 for example understands the method that data insert of carrying out, described data access is to insert by the data call through data page, data by the SMS paging insert, carry out by the data access of user's request, subsequently, portable terminal 100 is measured the information that is used for the estimated position, measured information via packet data exchanged center 600, and be sent to device 700.
But,,, in the example at packet data exchanged center 600, only need gps measurement data and sub-district id information through 700 needs sub-district id informations of device in the example of mobile switching centre 500 according to prior art.That is to say, be not identified for sending the standard of temporal information that come and go as yet to device 700.
Simultaneously, though used information two-way time, in the example of the position of estimating portable terminal, it is difficult preventing to produce a large amount of mistakes.
Accurate location estimation for portable terminal it would be desirable, mobile communications network is configured to include only a base station.
But cost and other reasons owing to equipment are configured to comprise base station 300 and repeater 210,220 and 230 with mobile communications network, as shown in Figure 4.Usually, be connected with 2 to 5 optical repeaters 210, be used for service and cover expansion.Equally, embedded repeater 220 and RF repeater 230 in each shadow region, have all been set up.
Because optical repeater 210 is connected with base station 300 by optical cable, so can analyze, the factor that makes signal delay is that the delay by the delay of optical cable and optical repeater 210 self causes.
In the example of RF repeater 230, can provide service by base station and optical repeater.Therefore, if service provides by base station signal, the signal delay factor of RF repeater is caused by the delay of RF repeater self so.Equally, if service is what the signal by another repeater provided, delay factor is caused by a plurality of delay factors so, for example delay that causes between RF repeater and another repeater, the delay of the delay of RF repeater self and another repeater self.
Especially, in the example of optical repeater 210a, because the optical cable between base station 300 and the optical repeater 210 is not installed as directapath, it is very difficult therefore wanting estimated delay.Therefore, in the repeater zone beyond the direct service area territory that is exceeding the base station during position of estimating user terminal, can a large amount of mistakes of generation in two-way time itself.This causes producing many mistakes in the estimated value of position.

The present invention uses O﹠amp; The reason of M server 530 is, mobile communication management person uses special circuit to come cascade at the O﹠amp of middle body usually; The data of M server 530.
According to the present invention, utilize circuit calling that has voice service and the packet call that is used for data, services, location information message can be sent to device 700.
Figure 11 and Figure 12 illustrate the flow chart that sends the process of positional information to the circuit calling of fourth embodiment of the invention according to second embodiment of the invention by utilizing.
With reference to Figure 11 and Figure 12, suppose the position of the predetermined portable terminal of client-requested, GMLC430 receives positioning service (LCS) request in the step of S1100 representative, and sends the routing iinformation request of request positioning service in the step of S1102 representative to HLR510.
The routing iinformation request is used to discern mobile terminal affiliated mobile switching centre.
In the step of S1104 representative, the information of the mobile switching centre of HLR 510 under GMLC 430 transmissions relate to portable terminal 100, and the position that GMLC 430 asks users' (portable terminal) to mobile switching centre 500 in the step of S1106 representative.
In the step of S1108 representative, mobile switching centre 500 carries out to portable terminal 100 and sends paging signal, carries out authentication and encryption, and allows to be provided with the connection between base station controller 400 and the portable terminal 100 in the step of S1110 representative.
Then, in the step of S1112 representative, mobile switching centre 500 sends the LCS notice to portable terminal and calls, and receives corresponding response signal in the step of S1114 representative.
In the step of S1116 representative, mobile switching centre 500 sends the positioning reporting control messages to base station controller 400.
In the step of S1118 representative, when receiving the positioning reporting control messages, base station controller 400 sends to portable terminal and measures control messages.
In the step of S1120 representative, portable terminal 100 sends the position data that portable terminal is located by measurement report message to base station controller 400.
According to the present invention, by utilize sub-district ID and two-way time information estimate in the situation of mobile terminal locations, base station controller 400 in the step of S1122 representative to the sub-district ID of base station controller 400 request portable terminals and two-way time information.In the step of S1124 representative base station 300 to base station controller 400 send portable terminals sub-district ID and two-way time information.
At this moment, in the step of representing to S1132 by S1126, suppose that the information that portable terminal sends is GPS information, then SAS 420 utilizes the position of the GPS information calculations portable terminal that base station controller 400 located, and information via mobile switching centre 500 that calculates and GMLC 430, and be sent to client.
Simultaneously, in the step of S1134 representative, in the situation of the two-way time of utilizing portable terminal, base station controller 400 by with the location dependent information (as the sub-district id information) of portable terminal and two-way time information package, produce location information message, and the location information message that is produced is sent to O﹠amp; M server 530.
In the step of S1126 representative, pass through O﹠amp; M server 530, location information message are sent to the position estimation device 700 that is present in the external network.
In the step of S1138 representative, position estimation device 700 by utilizing repeater location information message and the latitude and the longitude information of two-way time and base station and repeater come the estimated position, just as database is managed by NMS 520B, and to the estimated position of GMLC 430 transmissions.
Though top interpretation base station controller 400 produce location information message, those of ordinary skills it must be understood that, O﹠amp; M server 530 can produce location information message.
Figure 13 and Figure 14 illustrate the flow chart that sends the process of positional information to the packet call of fourth embodiment of the invention according to second embodiment of the invention by utilizing.
When using packet call, between the GMLC 430 of Figure 11 and HLR 510, carry out the process that obtains routing iinformation in the same manner.But in packet call, different is to the position of Serving GPRS Support Node 600 request portable terminals, rather than to mobile switching centre.
After identifying mobile terminal affiliated Serving GPRS Support Node 600, in the step of S1300 representative, portable terminal 100 is to Serving GPRS Support Node 600 request services.Therefore, connection between base station controller 400 and the portable terminal 100 is set in the step of S1302 representative.
Then, in the step of S1304 representative, SGSN600 carries out the safe handling operation of portable terminal 100.After finishing the safe handling operation, portable terminal 100 sends service call to Serving GPRS Support Node 600 in the step of S1306 representative, and Serving GPRS Support Node 600 sends the positioning reporting control messages to base station controller 400 in the step of S1308 representative.
Because S1310 is identical to the step of S1132 representative with S1118 to the step of S1324 representative among Figure 14, therefore ignores relevant details.
Simultaneously, in the step of S1326 representative, suppose information that base station controller 400 is obtained be portable terminal location dependent information and two-way time information, base station controller 400 then of the present invention is by producing location information message with these information package, and the information of packing is sent to O﹠amp; M server 530.
At this, O﹠amp; But the generation of executing location informational message in the M server 530.
In the step of S1328 representative, the location information message transmission is through O﹠amp; M server 530, and be sent to the position estimation device 700 that network-external provides.
In the step of S1330 representative, position estimation device 700 is by not only utilizing the information included in the location information message and the two-way time of repeater, also utilize the latitude and the longitude information of base station and repeater, thereby estimated position, just as database is managed by NMS 520, and to the estimated position of GMLC430 transmission.
As mentioned above, base station controller 400 or O﹠amp; M server 530 can calculate the position of portable terminal more accurately, this owing to portable terminal two-way time information and other positional information relevant information pack together, and the information of packing is sent to the estimation unit that network-external provides.
Simultaneously, as Fig. 5 and Fig. 5 in the identical systems as shown in Fig. 8, provide base station 300 in the ending of the system that carries out the mobile communication service, and repeater 200 is used for the expansion service radius and eliminates the shadow region.
The zone of the service radius of many base stations greater than the relay services radius itself arranged now, even service radius is according to certain zone and position changeable.According to being associated someway with the base station, present employed repeater comprises that optical repeater (and/or the interior repeater of building) and RF repeater (are commonly referred to repeater, non-ly be connected to the base station wiredly and comprise digital band conversion repeater, little repeater, ICS repeater and compactness/miniature indoor repeater).
If portable terminal is positioned at the direct overlay area of antenna for base station, then can be by be able to estimate the radius between base station and the terminal two-way time relatively accurately.
But, in optical repeater or building, providing in the situation of portable terminal in the zone of repeater and RF repeater, the measured value of two-way time has sizable two-way time of value, and this is because of carryover effects, as self delay component of optical cable or repeater.This can cause producing a large amount of mistakes when the radius of measuring between base station and the terminal.To the classification of the delay component of each coverage be described to Figure 17 with reference to Figure 15 hereinafter.
Figure 15 for example understands the time delay in the base station service areas.
With reference to Figure 15, direct service area territory, base station comprises the delay (BaseStation_Delay) of base station self, and the Radio Link that arrives portable terminal postpones the delay (Terminal_Delay) of (Base Station_RF_Delay) and portable terminal self.Be worth by following formula 1 total two-way time and determine.
[formula 1]
Total two-way time delay=Base Station_Delay+2*Base Station_RF_Delay
Figure 16 for example understands the time delay in the coverage of optical repeater.Figure 16 for example understands by utilizing optical cable and optical network unit 240 and 250 to carry out the structure of the connection between base station 300 and optical repeater 210.
With reference to Figure 16, the delay of light-repeating ship coverage comprises the delay (BaseStation_Delay) of base station self, the delay of portable terminal self (Terminal_Delay), through the delay (Optic_delay) of optical network unit 240 and 250, delay of optical repeater self (Repeater_Delay) and optical repeater postpone (Repeater_RF_Delay) to the Radio Link of portable terminal between base station 300 and the optical repeater.
At this moment, total two-way time, value was determined by following formula 2.
[formula 2]
Total two-way time delay=Base Station_Delay+Terminal_Delay+2*Optic_Delay+Repeater_Dela y+2*Repeater_RF_Delay
Figure 17 for example understands the time delay in the coverage in the RF repeater.
With reference to Figure 17, RF relay services zone comprises the delay (BaseStation_Delay) of base station self, the delay of portable terminal self (Terminal_Delay), Radio Link between signal source base station (female base station) and the RF repeater postpones (BaseStation_Repeater_RF_Delay), and the delay (Repeater_Delay) of RF repeater self and RF repeater postpone (Repeater_RF_Delay) to the Radio Link of portable terminal.
At this moment, total two-way time, value was determined by following formula 3.
[formula 3]
Total two-way time delay=Base Station_Delay+Terminal_Delay+2*BaseStation_Repeater_RF_D elay+Repeater_Delay+2*Repeater_RF_Delay
In the superincumbent explanation, base station self postpones, and portable terminal self postpones, and optical repeater self postpones and RF repeater self postpones to measure its each length of delay respectively.That is to say,, therefore measure this length of delay without any problem because each system and terminal have the standard of definition length of delay when postponing to produce.
The problem of a maximum is the optical network unit between base station and the optical repeater and the delay component of optical cable.Because in fact be difficult to make the optical cable between base station and the optical repeater to be installed to be directapath, so mounted optical cable is longer than the actual range between base station and the optical repeater.If accurately manage these data, just can utilize this database to measure length of delay at an easy rate as database.In fact, this mounting distance is not accurately managed as database.Equally, the RF repeater too.
In order correctly to estimate the position of portable terminal, just must in each service area, correctly measure value two-way time by repeater.Therefore, according to the present invention, repeater 200 is connected with measurement of round trip time unit 540.
Here, two-way time, analytic unit can be 1/16 chip.Optionally, other unit can be used.
Figure 18 for example understands the structure of optical repeater coverage according to an embodiment of the invention, and Figure 19 also for example understands the coverage structure of RF optical repeater according to an embodiment of the invention.
As above-mentioned, use two-way time of portable terminal and repeater two-way time the estimated position element be called as position estimation device.This element can be SAS 420, the position estimation device 700 that SMLC 410 and network are outer.
Value two-way time of measurement of round trip time of the present invention unit 540 measuring light repeaters 210 and RF repeater 230 is with the compensated position misjudgment.Preferably, this measurement of round trip time unit 540 can directly be wiredly connected to the debugger port of repeater.
By direct connection debugger port, the head of measurement of round trip time unit 540 can remain a head, but the delay energy minimization between repeater and measurement of round trip time unit 540.
Equally, measurement of round trip time unit 540 can be the portable terminal that the user handles.Different is, measurement of round trip time unit 540 can be previous terminal of installing, and whether vicious information is to NMS 530 in the RF test of relevant repeater and the repeater thereby launch.
As above-mentioned, because in the state that minimizes delay therebetween, measurement of round trip time of the present invention unit 540 is connected with repeater, therefore, value two-way time that measurement of round trip time unit 540 calculates just equals the value of calculating from formula 2 and formula 3, and does not consider to postpone from the Radio Link of repeater and portable terminal.
Therefore, calculate by following formula 4 and formula 5 respectively the two-way time of optical repeater and RF repeater.
[formula 4]
Two-way time=the Base of optical repeater
staion_Delay+Terminal_Delay+2*Optic_Delay+Repeater_Delay
[formula 5]
The RF repeater two-way time=Base staion_Delay+Terminal_Delay+2*Basestation_repeater_RF_De lay+Repeater_Delay
Because measurement of round trip time unit 540 directly is connected with optical repeater or RF repeater, so by only using a head to keep trafficwise, can be sent to position estimation device (just the two-way time that measurement of round trip time unit 540 is measured, SAS, one of position estimation device that SMLC and network provide outward)
Measurement of round trip time unit 540 emission measurements two-way time information operation can be the same with the calling process operation of Figure 11 and Figure 12.Equally, in order to estimate the position of portable terminal 100, can in advance this operation be sent to position estimation device 700 and storage.
In the situation of the information two-way time of mobile terminal receive 100, position estimation device relatively receives two-way time information and repeater two-way time.
Suppose that this portable terminal belongs to a plurality of base station service areas, can calculate the two-way time of this portable terminal corresponding at least one base station, position estimation device 700 determine corresponding to the portable terminal of at least one base station two-way time information whether greater than information two-way time of optical repeater that belongs to each base station or RF repeater.
If the portable terminal of certain base station two-way time information greater than the optical repeater that belongs to relevant base station or information two-way time of RF repeater, position estimation device 700 determines that portable terminals 100 are in the coverage of optical repeater or RF repeater.On the contrary, device 700 determines that portable terminal 100 is in the service range of base station.
After determining the coverage, device 700 of the present invention is estimated the tram of portable terminal by with reference to the base station and latitude in the repeater and the longitude information that are stored among the NMS520.
For example, suppose to determine portable terminal 100 in the coverage of given trunk device that position estimation device calculates the distance that portable terminal is arranged in relevant repeater by following formula 6.
[formula 6]
To the distance of repeater=(portable terminal two-way time-repeater two-way time)/2*3*500
Simultaneously, suppose that portable terminal 100 is in the base station service areas, then calculate the residing distance of portable terminal in the base station by formula 7.
[formula 7]
To the distance of repeater=(portable terminal two-way time-repeater two-way time)/2*3*500
According to the present invention, position estimation device can receive value two-way time corresponding to the portable terminal of at least one base station, in this case, position estimation device can be estimated the position of the portable terminal 100 of being correlated with by the distance of calculating portable terminal 100 in each base station repeater of this base station (or belong to).
Figure 20 for example understands an example, and this example is for example understood according to of the present invention by utilizing the location estimation method of two-way time.Illustrate network-external position estimation device receiving position information message that provides and the example of estimating the process of mobile terminal locations is provided Figure 20.

Table 8 has shown the location information message that measurement of round trip time unit 540 and portable terminal 100 are sent simultaneously.RTD[0] be value two-way time corresponding to the portable terminal of base station A.RTD[1] be value two-way time corresponding to the portable terminal of base station B.
In Figure 20, portable terminal 100 is made up of two heads.
Simultaneously, the unit 540 two-way time that is in the state that is connected with a head calculates two-way time by formula 4.
With reference to Figure 20 and table 8, corresponding to two-way time of the portable terminal of base station A300-1 be 2380, and corresponding to the two-way time of the portable terminal of base station B300-2 be 940.
For base station A, owing to portable terminal two-way time 2380, be positioned at the coverage of optical repeater so determine portable terminal 100 greater than the two-way time 2200 of the optical repeater that is connected to base station A.
Simultaneously,,, and do not have repeater two-way time, be positioned at the coverage of base station B so determine portable terminal 100 because two-way time of portable terminal is 940 for base station B.
Therefore, can calculate by formula 6 and 7 by the radius based on the repeater of base station A and base station B that can calculate two-way time, as follows:
Based on the radius of the repeater that is connected to base station B=(2380-2200)/2/16*3*500/3840000=440 (m)
Based on the radius of base station B=(940-640)/2/16*3*500/3840000=732 (m)
At this, 1/16 chip is an analytic unit, can realize by the resolution capability that changes each receiving chip manufacturing company.
In the situation of utilizing said method calculating based on the radius of repeater and base station calculating, as shown in Figure 20, the position of portable terminal 100 can be estimated exactly.
In not using the situation of estimating mobile terminal locations two-way time, different with the present invention is to produce big mistake.
For example, calculate the radius based on the two-way time of base station A, big mistake produces as follows.
Based on the radius of base station A=(2380-2200)/2/16*3*500/3840000=4730
The present invention can discern the coverage of portable terminal, thus estimated position exactly.In addition, owing to comprise in the situation of a plurality of repeaters that a base station the present invention can check that portable terminal is arranged in the coverage of which repeater.This makes it possible to estimate position accurately.
Simultaneously, when repeater provides service in building in utilizing building, suppose that portable terminal is in trafficwise,, therefore have multiple possibility can check that a head provides by location information message because repeater has the received signal of very strong portable terminal.Particularly, in this case, identifying the user two-way time by repeater, to be positioned at building just enough.
