Description

200541356 IX. Description of the invention: [Technical field to which the invention belongs] The present invention is related to the need to use the secondary clock which has been previously corrected by the primary clock, which is not available, and accurate Time information system. ^ More specifically, the present invention relates to the conversion of time information in a mobile terminal using a positioning system based on a signal received from a transmission source. In particular, it relates to mobile terminals that receive radio signals from both satellite satellites, satellites (such as global satellites, GPS) and terrestrial wireless networks. [Prior Art] Background Technology for locating mobile radio terminals using signals received from one or more transmitters has been widely used for many years. These systems include terrestrial networks (e.g., long-range radio navigation systems (Loran)) and satellite networks (e.g., GPS and GaUileo) that are deployed specifically for the purpose of locating the receiver, and A method using a general-purpose radio network such as a cellular phone network φ (for example, WOA · 97_1 1384) or TV (television) and a radio transmission network (for example, EP-Α-0303371). In a cellular mobile phone network, for example, the location of a terminal can be based on the identity of the service plus an identifier such as the interval between the service transmitter and the terminal. Information on the strength of the transmitter's signal, or the angle of incidence of the received signal. Observed time difference of arrival (〇TDA) using the signals received at the terminal from two or more transmission sources Improved positioning. Using only signals available within the cellular radio network, the method 99189.doc 200541356 Γ provides good position accuracy. '", These methods need to determine the transmission " of The accurate transmission time offset is used to solve the positioning equation. This can be done using a position measurement unit (lmu) with an additional receiver. Place the LMU at a known location so that it can be measured at a value of 0. Convert directly into a network timing model (see, for example, WOO_A_〇〇_73 8 Ub or 'Available—a technique (see w〇_a 孤 73δΐ4), in which, for example, by Two geographically different terminal pairs at unknown locations come from

Measurements of signals from many geographically different transmitters at known locations can be used to calculate the timing of the terminal and all timing offsets between the transmitters being measured without the need for an LMU. Zhushi GPS's sanitary positioning system provides an accurate solution if the receiver can receive enough satellite signals. Satellites are about common time bases for defining standard time for two worlds, such as GPS time or Global System Time (: TC). For example, each satellite in the 'constellation' within GPS has a stable atomic clock whose time is continuously measured and compared to a single-reference clock located on the ground. Guide the time of each satellite clock to align it with the reference clock, and acquire—a three-parameter model describing the time difference between the two clocks. These three parameters are uploaded to the satellite and broadcasted by the satellite as a clock correction parameter. After correction based on these parameters, this has the effect of closely aligning the satellite clock with the ground reference clock. Satellite; t-bit I can work well without obstacles between the receiver antenna and the antenna, but in the building or when there are obstacles, the Rong and other systems do not work well or do not work at all . A "π problem is that it takes a long time for cold start of these systems to be achieved. The first 99199.doc 200541356 continuously tracks the satellite signal first fix, and therefore when such systems At times, these systems work best.

GPS time of the arrival time of the material bit. ’Time or frequency is used for analysis. In another example (see WO-A-99-_47943), the mobile cellular telephone network is adapted to receive GPS signals at a base transmitter station (BTS) to allow it to calculate the location of the mobile phone. In a further development (see US-A-2002-0168988), the GPS unit has a position determination system (PDE) including a reference signal receiver, typically a part of a mobile communication system, and a reference to be received by the reference signal receiver Part of the signal is transmitted to the PDE to provide additional timing data that can be used to assist the operation of the GPS unit. It has been well known to me to send auxiliary information via links in this technology over the years. One of the earliest examples appeared in the 1986 White Sands Missile Range Control Interface literature (White Sands Missile Interface Control

Document) discloses a position report via a two-way communication link, which allows conversion of a virtual range or calculated position, often in WGS84 format based on a geodetic coordinate reference system as defined. In 1986, the ICD GPS 150 awarded to potential bidders of the range applicati joints programme by the US (US) government specifically incorporated support for mobile GPS receivers. And time information transmission. Since 1986, data formats such as 99189.doc 200541356 have actually been used to support mobile GPS receivers through two-way data links. Providing supplementary Beko to satellite positioning system receivers can enhance their effectiveness. In addition, accurate timing assistance reduces the complexity of related chip sets. Aid materials can include three or more of the three elements: a) satellite information, b) time assistance, and c) an estimate of the receiver's position. The method known in the art is, ‘For a reason’ a link to constantly monitor satellite information

The server that provides one or more satellite information of 彳 A Θ ^ ^ reference receivers provides health M Λ. In the GPS system, υ ^. Ύ, if the satellite signal can be received, the GPS receiver can also directly obtain the media from the satellite signal through the GPS receiver. Time assistance can be obtained from network signals whose timing has previously been associated with the satellite time base by means of a network-based stunner. The estimation of the receiver position can be obtained using a network positioning method, such as a 0TDA-based method. In all cases of this technology, the data channel provided by the automatic cellular network is used to send auxiliary data to the GPS receiver. x In my WO-A-00_73813 and WO_A_〇〇_73814 (these cases are incorporated herein by reference), I describe a communication system and method that constructs and maintains a defined cellular radio network Timing model of the timing relationship between the transmitters in the road. The system also calculates the position of the receiver. By correlating the timing of signals from one or more transmitters of the system with the time base, this network timing model can be used to infer the relative time of signals transmitted by any transmitter in the network relative to GPS Based on the timing, and thus timing assistance information is provided to the GPS receiver. Position estimates can also be provided to the GPS receiver. Other references describing auxiliary systems include uS_a_6,429,815 99189.doc 200541356 US-A-2002-0075942, US-A-2002-0068997, US-A-2002-0123352, WO-A-02-091630, and WO-A -01-33302. In US 6445927 (King et al.), A method for calculating the location of a base station in a communication network is described, which relates to obtaining GPS positioning information from a GPS device carried in the terminal and using a mobile terminal pair A measurement of the arrival time of a communication signal from a base station. A key feature is that the terminal must be located at least three geographically separated before a solution can be obtained

In the position. The present invention does not care about the location of the base station as it is the information provided within the method. In US 6603978 (Carls_ et al.), A method and device are provided for assisting to provide time information to a positioning terminal via a wireless communication signal during an active call session that does not necessarily synchronize a traffic channel and a control channel. GPS receiver. Unlike the present invention, this is achieved using a location measurement unit (LMU) and a tritium receiver associated with a base station in the network, and the time offset is sent to the mobile terminal via a communication channel. In the patent application published as us 2000/0168988 A1 (Younis), by using a reference signal (such as a 'public broadcast signal') received in one or more receivers in a terminal and a network, Provide timing assistance to Sunny in mobile terminal. The terminal sends a fragment of the received reference signal together with a request for = help information to the network-based computing node to determine the offset from the reference date. ㈣ Use this data to get the GPS signal from the terminal. As previously stated: No GPS time offset in any of the 30 different networks is transmitted by the communication link. No, raw 99l89.doc 200541356

In addition, this & no meal will transmit a fragment of the reference signal through the communication link. It is always known that if satellite positioning technology is used to locate mobile reception benefits, the system is based on another signal (such as the service base station received from the cellular mobile radio network (" downlink ");) The signal) when ^ and being supplied with the help of the precise 4 time, it can be improved. This time helps the bio-bit receiver to reduce the range of time offsets it must detect for a given satellite signal. Producing accurate time helps to know the time relationship between the satellite signal of Hexing positioning system (satellite time base) and the downlink signal of the cellular network. Timings can be measured and correlated using an LMU installed at a fixed, known location, or a web-based system such as those described in ours 〇_A 〇〇738i3 and 〇a. 73814. One or more Gps LMu in the network can then be used to find the offset between the network timing and the GPS time base. In this case, time assistance is only available when the mobile terminal has access to a properly equipped terrestrial radio network. In addition, a large number of signal transmissions and message transmissions are required within the network and between the network and the mobile terminal. Corrected time information (meaning, time information precisely related to a reference time such as GPS time or time) can be used for many purposes. One of the purposes mentioned above-is to assist GPS or other satellite positioning reception by reducing the uncertainty of the signal's arrival time and thus reducing the range of time offsets that the receiver must search to detect the signal n to lock the news from a specific satellite. The corrected time information m is in the Very Long Baseline Interferometry (Long Baseline Interferometry). In the Very Long Baseline Interferometry, two radio astronomy 99189 at either end of the baseline (which can be thousands of kilometers long). doc -10- 200541356 w must be synchronized with each other so that the time accuracy is equal to the receiver bandwidth, the time accuracy corresponding to the bandwidth of P, 5MHZ is about 20ns). The present invention eliminates the need for signal-based transmission / message transmission to support network-based equipment as seen in today ’s technology, and assists in signal transmission in addition to day-to-day communication. Improvements have added wireless: S and provide robust timing assistance. We show that in a mobile terminal, these functions allow the terminal to autonomously establish the relationship between the health time base and the network timing. In particular, it should be noted that the characteristics of the terminal blood,. According to the present invention, the communication is not necessary. The system can be operated using only broadcast signals from the Internet, and does not need to be registered. [Summary of the Invention] To register, transfer or send any message. The first aspect of Ji Shuming provides a method for correcting the uncorrected time information in the terminal with one or more benefits. The one or the receiver can receive and can be extracted from it and carried by the corrected system. Correction = signal of time information 'and capable of receiving signals from which uncorrected time information carried by the uncorrected stable system can be extracted, the method includes the steps of: determining at the first terminal position; > secondary uncle Corrected time taken from the correct system-Beixun and uncorrected time information extracted from the uncorrected stable system: Time offset 'wherein the signal from the uncorrected stable ^ at the-terminal position Available: The travel time of the signal from the uncorrected stabilization system is known or judged, and the signal of the genital system is available; and from the second terminal location, 99189.doc -11-200541356 of the signal of the unsettled stabilization system is known or judged, and the judgement is to take the offset between Baili Chu and T to correct it. Uncorrected time information ... The present invention of the unified signal also includes a system for correcting the yarn yarn coffee > actions of the receiver ~ uncorrected time information within the frame, it can leopard ^ dead 忒One or more receivers * Only the corrected time information carried by the system takes the signal of the uncorrected time information carried by the uncorrected stable system. The system contains a time biasing fixed component, which The time offset between the corrected time f of the system used to determine the extracted 1 at the first terminal position and the uncorrected time information extracted from the uncorrected stable system, where at the first level Signals from the uncorrected stable system are available, the travel time of the signals from the uncorrected stable system is known or determined, and the signals from the only positive system are available; and The known or determined travel time of the signal from the uncorrected stabilization system at the second terminal position and the determined offset are used to extract the weight from the uncorrected stabilization received at the second terminal position. system The uncorrected time information of the signal. Therefore, the present invention makes it possible to convert the corrected time information within, ',' when the terminal moves from one location to another, for example, to help the satellite-based position determination system. Time information conversion can be used for any purpose in which the corrected time information is required, but the main corrected time reference is not available. For example, the system of the master can be the time base of a satellite positioning system such as Gps, and is connected by 99189. .doc 200541356 is received from the satellite receiving room. Equation 11 k 17 is used to determine the clock or original time of correction such as UTC :: can be t: time reference, for example, based on the quartz (maintained) to remain valid (stable) Time information system or equipment. For this purpose, the signals transmitted by the network or multiple transmitters can be used =, because these signals often come from devices that will show excellent coherent characteristics. Locked at the center point in the self-transmission. Two = same reference signal. In special cases, accurate time information may be required in the event that the satellite signal is blocked, is unavailable, or is otherwise unavailable but still receives network signals. The mobile terminal can work spontaneously without the assistance of sending from the network, which means that 'no additional basic structure located in the terrestrial network or the general need to transmit time information to the secret communication and transmission consumption . Alternatively, the mobile terminal may be assisted by a warship, and the server is connected to the terminal via an access road. As discussed later, the server can perform the calculations necessary to extract uncorrected time information from the uncorrected stable m. It should be noted that in this case, the information carried through the link is not lost: corrected time information 'in particular, no information from which time such as satellite time base or UTC universal time can be extracted' is compared with the previous Technology is different. When the positions of both the transmitter and the terminal are known, the travel time of the signal received from the uncorrected stabilization system at the first and second terminal positions can be determined. The transmitter position can be obtained from a database, or it can be decoded from one or more of the signals from an uncorrected stable system, or it can be obtained from a signal from another transmitter. The position of the terminal at both the first and second terminal positions 99189.dc, -13-200541356 can be obtained by any convenient means, for example, using one of the positioning systems described above. Usually, the return time of the signal from the service transmitter is generally known in the terminal of the communication network, because the terminal must advance its internal timing by this amount so that the serving base station can receive the return from the terminal in synchronization with the signals it sends. Signal. In some systems, the terminal must refer to its timing advance :: as the timing advance (ta) value. Therefore, in the case of an uncorrected stable system, it is not necessary to know the position of the terminal to determine the time offset when uncorrected. It is well known in this technology and can be achieved by any of the following methods: On the clock in the terminal, the time elapsed between the arrival of the special inter-marker in the signal (positive and uncorrected system) is measured, and then the toilet is described by now ..., silly U Correct the transmission delay between the transmitters 1 ~ ^. Under certain conditions, can the corrected time ^ be transferred from one uncorrected stable system to another uncorrected stable system ^ Since Tian Cong — ~ / ,,, first As favorable. (For example) When the signal from the network is not used by the brother, it is not correct. j 峪 When transmitting the signal of the descent, as in the second aspect of the present invention, the uncorrected time is provided in the automatic terminal which is capable of receiving crying 4 4 children and has one or more connected states. 2 The door In the method of Bei Xun, more than a dozen receivers can receive the time signal that can be extracted from i Hai Temple or the correction signal sent by the correction system carried by the correction system, and can receive the deprivation tool. Signals of uncorrected and uncorrected time information carried by the first and third-father's stable systems, the method 99l89.d〇e -14- 200541356 method includes the steps: determine the extraction self-correction at the first-end position The uncorrected time information of the 1st time of the school * information and extracted from the 1st husband's day-to-day time ^ / offset, where at the-terminal position comes from the first-uncorrected The signal of the stable system is available, < from the time of travel of the first-uncorrected system signal Λ P 4々4 η, the time of the retreat is known or judged, and the signal from the correction system is available At the second terminal position, the used 糸 is determined to be extracted from the first-uncorrected system information and 提" Two uncorrected stable "of uncorrected ^ said the second time deviation between inch mussel glycosides, ^^ ^ A from the 4th terminal position and the first uncorrected stabilization system signal is available, The first and the second uncorrected stable Li Tongdi's system, and the time of death of the δίι is known; and 4 is determined by the signal from the second uncorrected system at the third terminal position. Known or judged travel time and these first and second judged time offsets to correct the uncorrected time information extracted from the second uncorrected stable system signal received at the third terminal location The present invention further comprises a system for correcting unscrupulous messages in the mobile terminal having one or more receivers. 'These receiver or receivers can receive corrections which can be extracted from them.' The time information of the corrections carried by the system = the signal and can receive from it the first and second uncorrected stable information.

The system carries the uncorrected time reference signal of A1 and δK. The system includes: a time offset determination component for determining the time information and extraction of the secret correction extracted from the correction at the _ terminal position. Since the first time offset between the uncorrected stable 99189.doc -15- 200541356 of the uncorrected time information of the fixed system, the signal from the first uncorrected stable ^ at the end of the position: Yes, the travel time of the signal from the first uncorrected stable system is known or judged, and the signal from the corrected system is available;

::: offset determination means for determining at the second terminal position between the uncorrected time information extracted from the uncorrected system and the uncorrected time information extracted from the second uncorrected stable system Two time offsets, where the signals from the first and second uncorrected stabilizations at the second terminal position are available, and the travel time of Λ from the first and second uncorrected stabilization systems is known Or judged; and corrections, which are used for the known or judged travel time of the signal from the second uncalibrated stabilization system at the third terminal position and the first and second The two-point-to-day ratios are used to correct the uncorrected time information extracted from the signal of the second uncorrected stable system received at the three terminal positions of f. φ In the two aspects of the present invention, under certain conditions, different receivers can be used to receive signals from both corrected and uncorrected systems. In other cases, an integrated multi-purse receiver can be used. Similarly, the receivers used to receive signals from the two uncorrected stable systems may be the same or they may be different receivers. For example, the first uncorrected stable system may be provided by one or more transmitters of a GSM (Global System for Mobile Communications) mobile communication network, which requires a first receiver, and may be implemented by, for example, Broadband CDMA (Coded Multi-Directional Proximity) ) Or one or more transmitters on different networks of other systems to provide a second uncorrected stabilization system 99189.doc -16-200541356 system, which requires a second receiver. In the case where the same type of network element is used in two uncorrected stable systems (such as two transmitters) so that the same pure device can be used in each of these two systems, the feeder itself can still be Part of two different networks (eg, competing telecommunications companies) or parts of the same network operating in different frequency bands (eg, 'MHz and 1800 MHz in the case of a European dual-band coffee network). In the case of the uncorrected "for the service transmitter of the terminal in the communication network, the timing advance (TA) or round trip time (rttt) can be known. Therefore, it is not necessary to know the position of the terminal to measure the corrected The first time offset between the system and the first uncorrected system. Under the condition that the uncorrected system is another service transmitter (the terminal has moved so that the first transmitter is no longer a service transmitter) If the transmission time offset between the two clutches is known or can be determined, the TA or RTTT value of the new server may be used without knowing the terminal location. In (for example) according to this This is the case where the previous calculations made by the invention have produced a list containing the transmission time offsets of the items for the two transmitters in the terminal.---------------Or-or It can be a clock running inside the terminal or elsewhere, which is used to maintain the corrected time in a short period of time. In this case, the stability of the clock must be sufficient so that the error introduced during the hold period is small enough Irrelevant Yes. In this case, the second terminal position can also be the same as the first terminal position. ≫ As mentioned above, the correction system can be a satellite positioning system, and the stable system can be a communication network. One or more transmitters. Therefore, the present invention includes this special situation, and in particular includes the use of, "Synchronizer" 99189.dc, -17- 200541356 to provide corrected time information mark from the signal of the communication network. This aspect of the present invention uses the network-based positioning method described in My Purchases 100-73813 and 100-a_00. The method according to the first aspect of the present invention (used in a secret terminal that can receive signals from a transmission source in a terrestrial network and a satellite with a time base satellite positioning system, wherein the corrected time is carried by a synchronous marker (Information) may further include the step of: measuring the relative offset of the signals from the plurality of transmission sources in the terrestrial network and received by the terminal with respect to the time frequency of the first reference; or At the terminal and terminal positions, the phase wheel of time, phase or frequency relative to the second reference from the same transmission source and received by the terminal ^ :::::: input and receive_ relative to the phase of the received signal The three parameters construct a list of relative transmission time offsets; the difference between the first terminal position; which is offset between the third reference and the satellite positioning system; and the judgment time between the pre and full time bases is from the ground network.

Therefore, according to the second aspect of the present invention, the transmission source and the time base The satellite is determined: from the mobile terminal on the ground network, the synchronization mark number may further include the steps:, time, and time) At the prepared terminal location, the hard number from the ground network source and the terminal will pick you up.

The first, second, third, fourth and fifth references or any combination thereof may be the same reference in practice. The reference may be a signal received by the receiver, or another signal that may be generated locally (e.g., using a quartz oscillator). For example, the signal received by the terminal from the serving cell can be used as a reference, and the timing of signals received from other cells can be measured relative to it. Alternatively, an internal clock that is sufficiently stable during the knowledge period can be used as a reference. A position determined at any terminal location can also be provided to assist in obtaining satellite signals. Measuring the relative offset of the time, phase, or frequency of a signal from a transmission source in the terrestrial network and received by the terminal with respect to any reference may be a measurement made only for signals broadcast over the network, in other words, not When the terminal needs to send 99189.doc -20-200541356 to the network of '罔 4 β transmission source as the communication network, it is not necessary to register on the Internet. ^ Synchronous markers can be implemented in any convenient way, for example, they can be electrical signals or clock-shifted messages. It should be understood that the synchronizing marker can be used to determine: a search window used in a satellite positioning system such as GPS (the placement of the two. • the signal pattern of various signals transmitted by individual transmission sources can be used) In order to achieve the measurement steps of the relative offset of the signal received from the transmission source with respect to the time, phase or frequency of any reference, as explained in y and 3 and ._73814, the transmission source is the H network ( For example, 'in the case of GSM or WCDMA (Broadband Coded Multi-Directional Proximity) network', the signal mode can be a synchronous burst broadcast on the control channel, or it can be the frame boundary in the transmitted data stream. The list of relative transmission time offsets is a list of these signal modes relative to the round time measured by the third or fifth reference. The establishment of the third or fifth reference is included in the steps of constructing this list In which, the time offset of each pass is expressed relative to the third or fifth reference. For example, the third moxibustion = can be the time that a specific signal mode is transmitted by the selected transmitter, or it can be retrieved by Take all calculated passes The average value of the time offset is constructed. Once the preliminary and the first terminal positions are measured at different first and second times to construct the relative transmission time offset and the position of the mobile terminal, this function is not limited to only It is often advantageous to use two sets of measurements and, if necessary, use two sets to average the 1 measurements to reduce the effects of noise or multipath propagation. ^ 99189.doc 200541356 The first and second measurements are called shi *, and the brother of the day guards performs the speculations that correlate the health day basis with the timing of the network signal.

In addition, as described in WOO_A · 00-73814, these timing measurements can be obtained from a single terminal moving around the network at different times, and it is clear from the foregoing discussion that the present invention can Save money end scarf provides time conversion without any interaction with network-based computing nodes. However, 3 99189.doc -22- 200541356 According to our WO-A-OO-73 813 and WO-A-OO-73814, the calculation required to calculate the transmission time offset and placement can be too burdensome to be easily performed It takes place within the terminal, so it may be advantageous to use network-based computing nodes for this purpose. Another advantage is that the accuracy of the calculations can be enhanced by using measurements made by other terminals in the network, which are not easily available to the terminal. °, China Mobile Terminals are connected via communication link

At the position of the first terminal, the In the case of the fixed satellite time base time information on the road, the relative offset of time, phase, or frequency == the signal received by the terminal sends the measurement results to a computing node to calculate the second terminal position; The transmission source transmits and is shifted from the final transmission time; and, the received signal relative to the reference is adjusted from the individual transmission source to the calculated second terminal input delay to adjust these transmission time offsets; The second list of adjusted relative transmission time offsets; and; & the relative transmission time offset of the second list sent to the final transmission time offset of the first list and the second list of time Base = member And the reference and satellite_based synchronization marker Γ is recognized when building relative to the satellite positioning system: see Figure 1 and refer to the following discussion to further understand this method, which should be about what the terminal measures and between the terminal and the computing node: The history of the two signals in order to construct a synchronization marker corrected to the satellite time base. "/ See Figure 1 'The terminal 101 receives the signal from the transmitter 107 of the network 107 as the gate and measures the signal relative to the terminal's clock. The arrival of a specific target ::: 2: When the terminal is in position 1, 'tA1 is the reception time of the target in the signal from the transmitter A (transmitter 103, transmitter), and it is given by the following formula to 99189.doc -24- 200541356 Out: where ~ is the transmission time offset of the transmitter A and ε is the day of the terminal clock when the terminal is at the time of the clock. AmpM 彳 生 & & Relative to—The end of the pulse indicates the speed between the terminal and the transmission ⑶, and the helmet in the transmission medium Green Snow ,,, medium ,,,,, and radio waves. These measurements are also performed on the signals received from the autobiography _Β, mountain, and the special, and the entire set of measurement results is sent from the terminal 101 to the computing nodes in the network (the application is not shown in Figure i. The measurement time interval is very short, so that any deviation from the terminal ;; =: :) days, ㈣fGrm time_keeping) is negligible, as explained in == A · 73813 and W0-A · 73814. rr is the point-to-point calculation, i4 B, e μ, the position where ^ is generated, and the transmission time corresponding to the transmitter A, 1 and 2 are shifted by 1,-. Because the terminal settings are also calculated differently, and the transmitters α, β, can also calculate the corresponding positions of rA1, r, and #, known as BI rci rD 丨. Therefore, the signal from the long-time transmitter to the terminal can be shifted. (If the transmission time is adjusted by 间, the transmission time offset of the whole round is designated as βΑ1, βΒ1, β_β temple, then βΑ1 (for example) from the following The formula gives: 01 ^ Ai = ^ A + (rA1 / v) 1 The wood received at the terminal position 1 corresponding to the runners A, B, C, D = e is sent from the computing node to the cooking pot. Yesterday ... The reference stores the set of Go to the representation: =, the difference between the two values (for example, ") is received at the position 1 by the terminal from the eighth correction of the signal 99189.doc -25- The time difference between the corresponding marks in 200541356. (In practice, due to measurement errors and error mitigation techniques used at the compute nodes (such as averaging), this difference may not be exactly the same as the difference measured by the terminal). My applications WCUA-00 / 73813 and WO-A_〇〇 / 73814 also reveal how the terrestrial transmitters with frequency differences can be modified so that the time stamp of each-transmission line drifts relative to other time stamps. Such corrections can be applied to the value of 相应. Also, the referenced The case shows how to apply the step-by-step repair JL to the observed arrival time of the ground transmitter to compensate for the movement of the mobile terminal. As explained above, and according to the present invention, the terminal is also measured at the position The satellite positioning signal from which the satellite time base is extracted. Essentially, a clock signal is generated by a satellite receiver in the terminal, which indicates the satellite time. This time the pulse signal is received from one of the transmitters 103 It is said that the arrival of the mark in the signal of the transmitter A) is compared, and the signal of the satellite clock is measured. The time offset between the arrival of the signal and the sign of the mark is 仏 ~. φ base time, the arrival of the sign in the signal from transmitter A is at satellite time TA1, TA1 = ts + ΔίΑ1 (3)

The stored list of Ps can now be used to correct the arrival time of the markers received from the corresponding transmitters relative to the satellite time. For example, the sign in the signal from the network transmitter B will arrive at the satellite time τB1, TB1 = ts + ΔΐΑ1 + βΜ -βΒχ (4) In this way, the terminal receives corrections from satellite time at position 1 Signals from all network transmitters. 99189.doc -26-200541356

Now the terminal moves to another position (for example, position 2). At this position, it does not: receive the satellite signal 'but can receive signals from the network transmitter p, han, s = signal plus from the healthy set. At least—their signals from members (such as Chuanyi B). The terminal measures the signals received from all network transmitters p, R, s, etc. and B, and the entire set is sent from the terminal to the computing section. As explained above, the computing node performs calculations to produce: The values of the transmission time offset and the terminal position are extracted from the corresponding set of corrected transmission time offsets β ", ϋ, etc. The modified time offsets (or -subsets) are from The computing node sends it to the terminal and stores it as the first set in the terminal's internal memory. The terminal can now correct the signals received at location 2 and from one of the network transmitters | such as transmitting HP), The date of arrival. The satellite time corresponding to this is given by:

Tp2 = ts + ΔΐΑ1-^ Β1 + βΒ2 (5). At this point, the signal received by the terminal at the position 2 and received from the network transmitter ρ can obtain the corrected satellite time signal synchronization marker, which can be provided to the satellite receiver to help it detect the satellite signal. One of the assumptions underlying the method of the invention outlined above is that the relative transmission time offset of the network transmitter between the measurement at position 1 and the measurement at position 2 does not change. The W0_A_⑼_73⑴ and WO-A-00-73 8U of the i-person reveal how the situation of the drifting transmitter can be considered, and of course the value of β can be adjusted accordingly. Any of the methods for time information conversion in the mobile terminal disclosed above can be used to assist in finding the terminal location. Therefore, the present invention includes a method for determining the location of a mobile terminal of 99189.doc 27-200541356 satellite positioning system, wherein a satellite receiver according to the present invention is provided with corrected time information and terminal position information, and uses at least one of satellite signals To determine the location of the terminal. This method can be used to reduce the time required to calculate the location of the terminals in the satellite positioning system. You can use only satellite signal measurements to determine the location or you can improve the location judgment by combining satellite and network signal measurements. In the absence of satellite signals sufficient to obtain a complete position and time solution, it is possible to obtain the satellite time base from the network timing corrected according to the method of the present invention, and thus reduce the number of satellite signals required. For example, a 3D position plus time solution requires measurements from signals from four satellites. If the time component is provided by the synchronizing marker, the three 'quasi-location solution can be acquired using only three satellite signals. Therefore, the present invention also includes using a synchronous marker to replace the signal from the satellite to position. # • The present invention provides a hybrid architecture that combines satellite positioning systems with the use of ground communications transmitters, networks, and systems. The results of summer surveys from terrestrial radio networks can be used to generate and maintain a list of the timing relationships between these two systems, and this list is related to the time base of the satellite positioning system. The niche system can be Gps, Galile, or any other system. The terrestrial transmitter network can be a cellular phone network based on GSM, WCDMA or other cellular systems, or it can be a transmitter network for radio or TV broadcasting or a different terrestrial radio network. The positioning produced by 99189.doc -28- 200541356 generally follows a procedure. Low-precision cell-level locations are immediately available, followed by network-derived positioning, and are referred to as satellite-derived positioning. In the case where the position cannot be calculated using the satellite system (even using the assistance), the present invention can still provide positioning based on the timing measurement of the terrestrial network. This provides a more robust system, which avoids complete positioning failure compared to unassisted satellite positioning. In cases where auxiliary data cannot be generated from terrestrial network signals, satellite I positioning is still available. The spontaneous provision of inter-temporal help and position help not only helps to improve accuracy, but also achieves faster first-time positioning (due to maintaining the π order of transmission time offset), longer battery life, or lower Communication usage is helpful. Since fewer correlators are needed, it also allows the use of simpler Shi Xi chips for satellite positioning systems. The beginning can be achieved by performing spontaneous or partially assisted location positioning. • Establishing a satellite time base to the radio network. Any further satellite positioning (even with assistance) can be used to maintain the timing relationship between the satellite and the terrestrial radio network. The location of the ground network transmitter can be obtained from the database server and the identification of the horse is performed in the terminal without the assistance of the network-based computing node (server). It can be broadcasted by communication channels, or it can be obtained from offline resources such as CDROM (Compact Disc Read Only Memory), flash memory devices or manual input. This information is relatively static and requires only occasional updates. 99189.doc -29- 200541356 The present invention is particularly suitable for tracking mobile terminals, in which the use of both satellite positioning and ground OTDA positioning enables continuous and seamless tracking of outdoor and indoor terminals across multiple environments. Preferably, the mobile terminal incorporated in the present invention comprises a mobile honeycomb receiver operating on a WCDMA network and-0 1 ^ receiving cry. Transfiguration also includes the media that carries the instructions of the group, which should be loaded into the package. When in a terminal containing a satellite positioning system component, the terminal can be caused to perform the method of the present invention. The present invention also includes a mobile terminal of satellite positioning system, the terminal includes: a time offset correction component, which verifies at the first terminal position that the time f information extracted from the satellite μ system is corrected and the stability is extracted from the uncorrected system.

Then, the values of β are sent back to the terminal ιοί via the communication link 302, where they are then stored in the network timing list image.

The GPS module 201 in the terminal 101 in FIG. 2 or FIG. 3 receives and measures signals from the satellite 102 of the GPS system 100. It uses timing measurements on signals from the satellite network ι〇〇 to calculate the location of the terminal, as described below. FIG. 2 further illustrates signal transmission and data flow in the terminal 101. The oscillator circuit 206 provides a clock sequence signal for both the GPS module 201 and the GSM module 202. The signal of the service cell of the GSM network received by the module 202 is used to adjust the frequency of the oscillator so that it is consistent with the received GSM signal, that is, the signal generated from the adjusted oscillator clock signal and the The signals generated by the received GMS signals match. The clock signal generated from the oscillator 206 is provided 211 to the GPS module 201 and also 216 to the GSM module 202. The OTDA value and other measurement results made by the GSM module 202 are transmitted to the general-purpose processor 205 via the link 214.

A signal indicating GPS time is transmitted from the GPS module 201 to the general-purpose processor 205 via the link 212. The synchronization marker signal generated according to the present invention is transmitted from the general-purpose processor 205 to the GPS module 201 via the link 213. With the software in the example of Fig. 2 or Fig. 3, the GPS timing signal 212 is used to establish the GPS system's time base relative to that maintained in the network timing list 99189.doc -33-200541356 208, 308. The relationship of one or more members in the list of transmission time offsets (values of α). This relationship is illustrated in the following table. This table describes the transmission time offset (column 2) for each BTS of the five BTS 103 AE (block 1) of the GSM network relative to a reference third reference "(Column 2). The signals received by the GSM receiver in the module 202 are used to calculate these transmission time offsets. Time is expressed in microseconds, and is a burst length (approx. 577 叩), because the method of measuring 1 at this point is uncertain. In this case, the third reference is calculated as the transmission time offset of one of the members of the list (103 C).

At some time after the terminal 101 is turned on, in step In 401, at the prepared terminal position, perform the first set of measurements on the BTS signal. At some later time, = in step 402, perform the second set of BTS signals at the "first end position". Measurement. The two measurement result sets are used to calculate the list of network transmission time offsets (values of α) in step 4.03. In step 402, the amount of BTS signals is further periodically performed. After each set of measurements, the list of transmission time offsets of 99189.doc • 34- 200541356 BTS 5fl is updated in step 403 after each measurement. Separately, in step 410, the GPS receiver obtains and measures the data from The signal of the satellite 102 'and a signal indicating the Gps time base are generated in step 412. In step 408, #this signal is associated with a third reference, relative to the timing generated in the third reference creation step 403 List of offsets. # (At the second terminal position) When a position request is made (step 404), the latest satellite data set is self-maintained in the local satellite information in the module 20 in step 405 Database 411 (which is known) is loaded. Focus on SG in Step The SM network signal calculates the position and provides the position as the initial position to the GPS module 201 via the link 217. In step 409, a synchronization marker 213 is generated in the general processor 205.

In step 413, the satellite signal obtained in step 410 is used to calculate the position of the mobile receiver, and in step 414, the position is output to a request 99189.doc -35- 200541356. The application executes a terminal wipe or software. "Servic is using a towel, as described above, to establish the BTS transfer time shift offset and measure the GPS time base in any GPS positioning, for example, the measurement made under the" clear weather "condition. Therefore, 'establish the relationship between the Gps time base and the ground transmission time offset' and as described above, these relationships are used to assist subsequent GPS positioning under poor conditions. The embodiment just described does not require the terminal 101 to communicate with the Gsm network to operate. Therefore, it is not necessary for the terminal to register on the network (which involves the terminal transmitting to the network), but only that the terminal can receive the signal broadcast by the coffee. As explained earlier, the calculation of the list of transmission time offsets can also be performed in a server connected via a radio link. Therefore, another embodiment using the terminal of FIG. 3 is described, in which the terminal 101 is used in a GSM network and the calculation is performed in a feeder 301 connected to the network. Although the communication between the terminal and the server may be, for example, via GpRS (General Packet Radio Service) or any other convenient means, in this case, such communication is via a short message service (SMS). Figure 5 shows a flowchart for this particular situation. Except deleting steps 40 and 407 and adding steps 402a and 403a, the flow chart elements shown in FIG. 5 and FIG. 4 are all the same. In this case, measure the timing offset of the GSM network signal in step 402 and send it to the network server 3 01 in step 402a, and do it at the network server 301 in step 403. Calculation. Then, the list of values of β is sent back to the terminal in step 403a. 99189.doc -36- 200541356 Another embodiment will now be described, in which the present invention is included in a positioning system in which a terminal can communicate with other servers connected to a communication network. Fig. 6 illustrates another example of a system embodying the present invention. In this example,

• Includes a communication link 110a-c between the external application server 106 (connected to the gSM-network 107 via the Internet 108) and the terminal 101. The communication link between the terminal 101 and the GSM network 107 is wireless. The communication link 1101 between the network 107 and the Internet 108 is generally implemented as a cable connection. The communication link 110C connects the server 106 to the Internet 108 and generally implements it as an electronic viewing connection. In #works, the application residing on the server 106 requests the location of the terminal 101, which calculates its location in the same manner as described in the previous example. The communication link 110a_c is used to return the obtained position to the requesting application. FIG. 7 illustrates another configuration embodying the present invention. In this case, another server 105 connected to the Internet 108 via the φ link 110 (1) contains static and semi-static configuration information such as satellite, star calendar, and clock correction information. And information about the geographic location of TS 103 such as TS 103. This information is broadcast to terminal 101. In another configuration, similar to the configuration described in the previous paragraph (using the system of Figure 7), The communication link as above is used by the terminal 101 to retrieve configuration information on demand. The information obtained from the server 105 is used to supplement the original and health information database in the terminal 101, especially for the terminal. The first operation of the day guard. As in the first embodiment, the initial position estimation and timing assistance are generated locally at 99189.doc -37- 200541356. Figure 8 also illustrates another embodiment. In this situation The GPS position calculation function is separated from the terminal 101, which communicates with the external position calculation device 1 09 for calculating the position of the terminal. The GPS timing measurement results provided to the position calculation device 109 are measured in the terminal 101.
