Below whole design idea of the present invention is described:
In radio honeycomb communication system, base station as the equipment providing communication service, for terminal equipment provides downstream signal and the upward signal of receiving terminal apparatus.Usually, the overlay area of single base station is a hexagon, and a large amount of group of base stations covers bulk zone altogether, as shown in Figure 2.
Fig. 3 gives the base station of CDMA (code division multiple access) and the time relationship of mobile terminal.Mobile terminal needs a reference time of estimation for sending chip, symbol, time slot, frame and system time.At steady-state, the reference time of mobile terminal is no more than ± 1 μ s with the first footpath time deviation of the respective base station downstream signal received.I.e. certain time T, the signal of the free T mark of base station transmit band, the reference time T of mobile terminal using the first footpath signal time of certain channel of base station received as oneself, in fact, the time T that mobile terminal receives has had a transmission delay than the transmitting time T of base station; Then send upward signal as benchmark to base station, time mark is T, and receive time mark that mobile terminal sends in base station when being the signal of T, the real time is delayed the transmission delay of twice than time T.
Up-descending timing relationship of WCDMA (Wideband Code Division Multiple Access (WCDMA)) is: at UE (subscriber equipment) end, the transmission time of up DPCCH/DPDCH (Dedicated Physical Control Channel/Dedicated Physical Data Channel) frame is the first footpath signal delay T of descending DPCCH/DPDCH or F-DPCH (fractional dedicated physical channel) frame detected
0chip, wherein T
0for constant value, be fixed as 1024 WCDMA chips.
Fig. 4 give LTE (Long Term Evolution) up-downlink frame timing relationship is: at UE (subscriber equipment) end, UE sends the time of up-link wireless frame i, needs the time advance (N than the corresponding downlink radio frame i received
tA+ N
tAoffset) × T
ssecond, wherein, 0≤N
tA≤ 20512,
for FDD (Frequency Division Duplexing (FDD)) pattern, N
tAoffset=0; For TDD (time division duplex) pattern, unless specified, N
tAoffset=624.
In CDMA, WCDMA and LTE tri-kinds of communication systems, or in some other communication system, mobile terminal sends the time of upward signal, is all with reference to descending signal time.Wherein, downstream signal time of directly receiving with end side time of the up transmission signal of CDMA as a reference; The descending DPCCH/DPDCH time delay T that the time that the up DPCCH/DPDCH of WCDMA sends receives than end side
0chip; Downlink radio frame time advance that the time that the up-link wireless frame of LTE sends receives than end side (N
tA+ N
tAoffset) × T
ssecond.In position fixing process, positioning equipment can for specific communication standard, that eliminates the downstream signal reference time sending upward signal and reception in conjunction with the downstream signal received and/or downlink signaling does not line up phenomenon, thus obtains the transmission time sum from base station to terminal equipment, from terminal equipment to positioning equipment.
As shown in Figure 5, when the downstream signal 405 that target device 402 and positioning equipment 403 detect respectively and upward signal 406 are all direct projection propagation, the ellipse 404 that it is focus that positioning equipment can be determined with base station 401, positioning equipment 403, wherein on ellipse 404 o'clock to the distance sum of two focuses be from base station 401 to target device 402, from target device 402 to the distance c*t1 of electromagnetic transmission corresponding to the transmission time sum t1 of positioning equipment 403, target device 402 is on this ellipse; When there is non-direct projection propagation in the downstream signal 408 that target device 407 and positioning equipment 403 detect respectively and upward signal 409, although target device is also on ellipse 404, but positioning equipment observe from base station 401 to target device 407, from target device 407 to the distance c*t2 of electromagnetic transmission corresponding to the transmission time sum t2 of positioning equipment 403, the ellipse determined is 410, it equally with base station 401, positioning equipment 403 for focus, but on oval 410 o'clock to the distance sum of two focuses be c*t2.In a word, the determined ellipse of distance that the Electromagnetic Wave Propagation time sum from base station to target device and from target device to positioning equipment observed according to positioning equipment is corresponding, this ellipse determines the outer limit in region residing for target device.
Detect the signal of target device first at positioning equipment after, the ellipse determined can only provide the outer limit in region residing for target device, this positioning precision generally can't meet the demands, and needs combination more measurement the location estimation of target device could be obtained more accurate.
As shown in Figure 6, positioning equipment, at 502 places, has detected the signal of target device 506, the ellipse 503 that to determine with base station 501 and positioning equipment position 502 be focus.Positioning equipment is moved to 504 places, detected the signal of target device 506, the ellipse 505 that to determine with base station 501 and positioning equipment position 504 be focus.Oval 503 and oval 505 have two intersection points 506 and 507, if in twice measurement, downstream signal and upward signal are all that direct projection is propagated, and so, target device is in a bit in intersection point 506 and 507; If in twice measurement, there is non-direct projection and propagate in downstream signal and upward signal, so can only determine that target device is in the inside, public domain of oval 503 and oval 505, intersection point 506 and 507 is only the point of the vicinity of target device present position, using the optimum position of intersection point 506 and 507 as search target device.
As shown in Figure 7, removable positioning equipment, at 602 places, has detected the signal of target device, the ellipse 603 that to determine with base station 601 and positioning equipment position 602 be focus.Positioning equipment is moved to 604 places, detected the signal of target device, the ellipse 605 that to determine with base station 601 and positioning equipment position 604 be focus.Oval 603 and oval 605 do not have intersection point, now assert that the measurement at measuring position 604 place of larger oval 605 correspondences is invalid measurements, and as far as possible away from this panel region in follow-up search.
By above-mentioned analysis, known wireless communication terminal localization method of the present invention, considers that non-rectilinear propagates the impact brought, the removable positioning equipment of use, has the high advantage of efficiency of positioning precision, location.
Above-described embodiment is the present invention's preferably execution mode; but embodiments of the present invention are not limited by the examples; change, the modification done under other any does not deviate from Spirit Essence of the present invention and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
