Abstract
The invention discloses a method for regulating a wireless positioning reporting period based on speed measurement. A core network is used for sending a positioning request to a service wireless network controller; the service wireless network controller sends a measurement request to a cell phone and a base station respectively; a requested party returns measurement information to obtain measurement error through simple calculation and to regulate the reporting period. The method obtains the measurement error through two ways, namely reporting speed through the cell phone or not through the cell phone. The invention adds the measurement process of user movement error on the conventional measurement method and dynamically regulates the relevant measurement reporting period by determining whether the user position change is rapid through comparing the user movement error, thus realizing the measurement accuracy and the optimization of the unlimited system resource.
Description
Technical field
The present invention relates to a kind of mobile phone wireless localization method, relate in particular to a kind of wireless locating reporting period control method based on tachometric survey.
Background technology
Along with the development of wireless communication technique, particularly the U.S. proposes after the emergency position service request, and the wireless location service more and more receives the concern of industry.
According to the participation classification that whether needs mobile phone, mainly be divided into two types for the location technology of mobile phone: the mobile phone location technology that needs the mobile phone location technology of mobile phone reporting information and do not need the mobile phone reporting information.
The former, network system need be passed through the signaling mobile phone, and needs mobile phone initiatively to report relevant metrical information just can determine the particular location of mobile phone.So, mobile phone is full of ideas separates it and is in the state of being positioned.And mobile phone also can need stop under the prerequisite that is positioned the user, by not reporting relevant metrical information and reporting the method for false metrical information, makes the privacy of positional information of oneself be protected.
But for the latter, owing to do not need the active of mobile phone to participate in, mobile phone can't confirm whether it is in the state that is positioned, and this protection for mobile phone location has caused certain difficulty.A typical case of these class methods just is based on the localization method of cell id.
According to location reference signals classification, mainly be divided into 3 types: based on the location of mobile phone cell id, based on the location of base station signal/mobile phone signal and based on the location of satellite navigation system for the location technology of mobile phone.Wherein, relatively poor based on the localization method precision of mobile phone cell id; Localization method based on satellite navigation system needs extra equipment and cost; Localization method based on base station signal/mobile phone signal does not need to add extras and have medium positioning accuracy substantially.
The third generation (3G, 3rd Generation) mobile communication system is the mobile communication system that present most countries in the world and area are all being used or will used.3GPP (3rd GenerationPartnership Project) has finished all relevant standard operations as the normal structure of 3G.
The suggestion of each side has been adopted in relevant wireless location aspect, 3GPP tissue, has adopted whole three kinds of station-keeping modes in its standard: based on the location of mobile phone cell id, based on the location of base station signal/mobile phone signal and based on the location of satellite navigation system.
For location based on base station signal/mobile phone signal, the method that has adopted mobile phone for measuring to report.By each signal of base station of mobile phone for measuring time of advent, and by the signaling report network.Network is then finished the function of calculating mobile phone location.
With the localization method based on base station signal/mobile phone signal time of advent is example, introduces the position fixing process in the 3G system.
Tradition based on the localization method of base station signal/mobile phone signal as shown in Figure 1.System has 111,112 and the 113 and mobile phones 12 with measurement capability in three base stations at least, and there are the signal 131,132 and 133 of radio transmission in base station and mobile phone, and the signal propagation time that correspondence measures is respectively t1, t2 and t3.Because the radio velocity of wave propagation is constant light velocity c, so, the distance of mobile phone and respective base station be di=ti * c (i=1,2 ...).With the respective base station is that the center of circle, di are that radius is drawn circle 141,142 and 143, and then the position of intersecting point of all circles that obtain is the mobile phone correspondence position.Mobile phone reports the emission of the base station signal of its measurement-accept time delay to give network system, and then network just can calculate the position of mobile phone according to these values.
Fig. 2 is the legacy system handling process, and its step is as follows:
Core net (CN) sends Location Request to service wireless network controller (SRNC);
Service wireless network controller prolongs the request of measurement to mobile phone (UE) the transmission indirect time receiving of base station;
Service wireless network controller sends mobile phone measurement reception-launch time request to mobile phone;
The mobile phone for measuring process;
Mobile phone prolongs measurement result to the indirect time receiving of service wireless network controller reporting base station;
Mobile phone reports mobile phone measurement result reception-launch time to service wireless network controller;
Service wireless network controller sends the request of base station latency measurement to base station (Node B);
The base station measurement process;
The base station is to service wireless network controller reporting base station emission time delay measures;
The service wireless network controller position location computation;
Service wireless network controller reports the position calculation result to mobile phone.
In the processing procedure, the cycle that measurement result reports fixedly installs.
About measuring the setting of report cycle, only depend on the height of the required positioning service grade of user in the present system: adopt the report cycle of weak point for high-grade customer service demand; Otherwise, adopt long report cycle for low-grade customer service demand.
In fact, under certain report cycle condition, user's the movement velocity and the measure error of system are proportional.For movement velocity user faster, if report cycle is longer, then in fixing report cycle, the user has moved bigger distance, and it is inaccurate to cause location estimation to get.Simultaneously,, then do not have difference between the measurement result that reports for twice, can cause the waste of system wireless resource if user moving speed is slow and report cycle is shorter.
