Description
Technical field
The present invention relates to mobile terminal Bearing positioning fields more particularly to a kind of towards the novel of mobile communication target
Active/passive Cooperative Localization Method and system.
Background technique
TSOA (incoming wave arrival time and)/TDOA (the incoming wave arrival time of traditional localization method such as based on protocal analysis
Difference) hybrid positioning technology, NLOS (non-market value) the inhibition calculation based on AOA (arrival bearing angle)/RSS (received signal strength)
Method and tracking technique can realize certain conditions based on DOA (arrival direction)/TSOA, TDOA/DOA multistation location technology etc.
Under target terminal positioning.But mobile communication is unlike short wave communication, easily tens kilometers even up to a hundred kilometers of communication distance,
Unlike radar signal arrival bearing then it is determined that, the property complicated and changeable of mobile environment makes above-mentioned any method all can not
Guarantee the accurate and reliable of positioning accuracy.
Meanwhile (positioning device except target terminal and base station claims for the non-cooperation of mobile communication target terminal
Be non-partner) position error is mainly derived from two aspects: first is that parameter estimating error, due to nonideal channel ring
Border, so that phenomena such as multi-path jamming, multi-access inference, non-line-of-sight propagation error and noise jamming is generally existing, these factors are all
It will cause the decline of positioning accuracy；The other is the error of location algorithm, this is on the basis of parameter Estimation since selection is different
Method for calculating and locating brought by calculate error.
Since non-cooperative localization is not involved in the communication interaction between mobile station and cellular network, the links of realization are positioned
Have the characteristics that its is special, technical difficulty is bigger, and problem to be solved mainly has the following aspects:
Measurement parameter obtains
Traditional localization method such as radio wave propagation time (TOA, TDOA), incoming wave azimuth (AOA), incoming wave signal strength
(RSS) etc., can they be obtained under the conditions of non-collaboration scenario and novel refined net by positioning table and positioning table should
How them are obtained, requires to further investigate.
Mobile communication system protocal analysis
Non- cooperative localization cannot get the support of mobile station and network, can only be with third-party identity to mobile station and Cellular Networks
The information transmitted between network can position after being intercepted and captured.Must according to 3GPP protocol specification to the aerial signals of intercepting and capturing carry out by
The signaling resolution of bit is excavated to the valuable information of positioning.But many to the relevant agreement of positioning in 3GPP protocol specification, work
It measures very big.
Error suppression technology
Non-market value (NLOS) is the biggest obstacle in wireless location technology, and high-precision error mitigation algorithm is research
Emphasis.In practice, due to the portability of positioning device, receiving antenna height can not reach base station height, and NLOS problem is more
Add serious.In general, paying the utmost attention to TOA and TDOA localization method, positioning accuracy is high.But TOA requires height to time synchronization, needs
GPS auxiliary realizes that mobile station is synchronous with positioning device；And TDOA only needs to synchronize or know time relationship between positioning device, it is real
It is now simple.
But from a practical point of view, whether based on algorithm or the passive type locating scheme based on agreement and undesirable.
First: target mobile phones are in most cases all in silent status, if passively waiting target user's triggering, can waste a large amount of
Time, and very high requirement is proposed to our positioning device operation duty personnel.On the one hand must in long period not between
Disconnected monitoring；On the other hand need when target user has communication service can skilled operation positioning device, quickly prepare judge mesh
Cursor position.Second: with the 4G even development of 5G mobile communications network scale and the very fast change in city, suburb architectural environment
It moves.The district environment of intensive high buildings and large mansions, complexity can all form the multipath effects such as more reflections, refraction, swarm forward
Motor vehicle produces a large amount of man-made noise, and rich and varied electronic product, which is widely applied, forms complicated electromagnetic environment.It is all
The multifactor positioning accuracy that can all make us declines, and location efficiency substantially reduces.The orientation range of original mobile target is just not
Greatly, if failing to catch only target user to trigger chance, even if caught target triggering chance and implemented positioning,
But position error is by chance very big, it is likely that causes to judge by accident.Therefore, the above method is not suitable for application in actual combat.
It in practical application, is positioned frequently with active trigger-type: periodically inducing target using certain strategy and continuously emit letter
Number, signal strength and direction are compared repeatedly, are constantly updated the position of positioning device to reduce target area, are passed through Step wise approximation
Mode realizes the accurate positioning to mobile communication target terminal.

Specific embodiment
A specific embodiment of the invention is explained in detail below in conjunction with attached drawing.
Common active trigger-type positioning includes two major classes: passive passive type localization method and system and active virtual base station
Active localization method and system.
Firstly, introducing passive passive type localization method and system: in order to effectively be positioned to target mobile phones terminal, needing
It enables stealthy calling module and carries out period induction formula (obfuscation short message either dials noninductive phone), purpose makes target terminal exist
Do not have it is any discover in the case where, excitation target mobile phones and serving BS establish of short duration communication connection, emitted with trigger signal,
Condition for validity is provided to implement scouting and positioning.Fig. 1 gives the General layout Plan of passive passive type localization method, this method
It is suitable for the positioning to the mobile communication target of all 2G, 3G and 4G.
In the program, needs to complete the identification to specific target terminal first, obtain its Temporary Mobile Subscriber Identity, which is logical
It crosses the method for fuzzy matching to realize: assuming that stealthy calling module is called with T0 seconds/time (T0 takes 6~8) of time interval
Target terminal is triggered, then the TMSI of target terminaliThe opportunity occurred in the sky, which should also be, occurs one per (T0- δ, the T0+ δ) second
Secondary TMSIiValue, it is assumed that in 60 seconds, according to the above-mentioned rule continuous stealthy calling target terminal 8~10 times, then receive in the sky
To a large amount of TMSI set in, carry out fuzzy matching according to the time interval of (T0- δ, T0+ δ), select and most possibly meet rule
The TMSI of ruleiValue is the identity of target terminal.In turn, instruction of keeping under strict control is issued by main control platform, keep under strict control certain 1 (or 2~3)
Temporary Mobile Subscriber Identity (can keep under strict control IMSI sometimes) completes the measurement to its uplink signal.Fig. 2 gives direction finding by taking 8 circle array antennas as an example
Position Design process.
Passive passive type localization method is with the advantages of system: 1. positioning devices itself do not emit signal, concealment is strong,
Low in energy consumption, energy conservation and environmental protection；2. positioning device itself has signal resolution function, in energy analytic function region multiple public network base stations
Broadcast channel and access channel data can be at up to 10 or more to obtain corresponding broadcast parameter and TMSI identification parameters
Target TMSI is found in base station range, and carries out power measurement and positioning, and sphere of action is larger.
But since the dependence to public network leads to by force very much distinct disadvantage, be mainly manifested in: 1. require public network signal to compare
By force, if public network signal is weaker in the working region of positioning device, and positioning device is either received due to being in non-partner
The effect that base station signal still receives target terminal signal all can be very poor, causes to be difficult to find target or is difficult to detect target
Transmitting signal；2. ' near-far interference ' phenomenon is serious, periphery strong signal base station can flood weak signal base station, cause positioning device without
Method receives weak base station signal, forms blind location area.A variety of causes leads to passive passive type positioning system table in actual use
Reveal the problem that stability difference is kept in control.
The active localization method of followed by active virtual base station and system: positioning device is by pretending to be virtual base station transmitting-receiving to believe
Machine (V-BTS, and referred to as ' virtual base station), broadcast and access information are sent on appropriate opportunity using V-BTS, induces target user
It is linked into positioning device；In turn, V-BTS constantly sends identification and asks for request, to obtain the IMSI of target terminal user
And realize that the attraction to target terminal user is hung up；Once hanging up successfully, V-BTS periodically initiates " measurement request ", pretends to be inquiry
Target terminal asks for measurement report information, and target is inveigled continuously to measure V-BTS transmitting signal strength and reporting measurement reports；Together
When, V-BTS can directly measure the uplink signal field intensity value of target mobile phones terminal, or receive what parsing target mobile phones terminal reported
Measurement report information, according to real-time reception to field intensity value size judge distance of the target mobile phones terminal apart from self-position,
To realize the positioning to target.The active active positioning signal process flow of virtual base station is as shown in Figure 3.
The active active localization method of virtual base station is with the advantages of system: 1. are influenced smaller, positioning device by public network
Own transmission signal, and the false base-station node that disguises oneself as is communicated with target terminal, as long as transmission power is slightly stronger than public network letter
Number and priority it is higher, it will be able to by target attraction come up, the power power degree of association very little between public network base station；2. power is surveyed
Amount is stablized, once target is attracted in V-BTS equipment and hangs up, V-BTS positioning device can control target by signaling
Terminal continuously reports field intensity value, and count off speed is quickly, maximum up to 2 times/second, until signaling control terminate or target terminal from
V-BTS off-grid.
But the active active positioning of virtual base station is the base station that disguises oneself as after all, and own transmission power, there are also disadvantage, bodies
Present: 1. have certain micro- radiation, and since V-BTS emits signal, long-term portable work has certain body spoke to user
It penetrates；2. sphere of action is small, V-BTS can only be effective to the target terminal in control zone, and itself is since transmission power is small and antenna
Highly low status, controlled region is little, for the V-BTS equipment of 20W power, most 500 meters of operating distance, and for 1W
Portable V-BTS equipment, only 100 meters or so of operating distance.It is more difficult that 3.IMSI priori knowledge obtains, it usually needs from operator
Its IMSI value is inquired according to the phone number of target by place, and trouble is implemented in operation.
Based on above content, sphere of action strong for passive passive type positioning concealment be wide but target control to keep stability poor
And active active positioning adsorbed target is firm, power measurement is stable but the lesser state of the art of sphere of action, propose towards
The active/passive co-located technology of mobile communication target: in unified hardware and software platform system, while passive passive type is realized
Actively absorption positions with active virtual base station for positioning, specifically, as shown in Figure 4.
By the uninterrupted listening broadcast channel of passive passive type, intercepted broadcast message is simultaneously sent to active locating module.

It monitors, specifically, by receiving uninterrupted monitoring broadcast channel by passive passive type, intercepts critical broadcast message
Such as SIB5, SIB11 and pilot channel quality Ec/N0, the letter such as frequency, scrambling code, identification code, Location Area Code of adjacent cells is obtained
Breath, and pass to active locating module.
