Description
Technical field
The present invention relates in the wireless system network interface message and wireless location method and system, relate in particular to utilize and arrive network interface message and wireless location method and the system that angle positions between many base stations and the mobile phone based on the location, base station.
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 whether needing the participation of mobile phone to classify, mainly be divided into two types for the location technology of collecting: 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 being decided to be reference signal 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 collecting.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 method that tradition is carried out wireless location based on the arrival angle of base station measurement mobile phone signal as shown in Figure 1.At least 2 of systems have 111,112 and one ones of base stations that arrive the angle measurement capability and have the mobile phone 12 that transmits, there are the signal 131,132 of radio transmission in base station and mobile phone, and the signal arrival angle that the upward signal that correspondence measures arrives different base station is respectively q1, q2.All obtain is starting point with the base station, be that the position of intersecting point of the ray of transmit direction is the mobile phone correspondence position with the angle of arrival.The base station reports the arrival angle of the mobile phone signal of its measurement to give network system, and then network just can calculate the position of mobile phone according to these values.Fig. 2 is the vertical view of Fig. 1.
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, adopted the method that reports of measuring of collecting based on base station signal/mobile phone signal.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.
Traditional wireless location method sees also Fig. 3, is described below.
Step S200: core net 20 issues Location Request to service wireless network controller 21.

Step S203: mobile phone 23 prolongs the request of measurement to the indirect time receiving of service wireless network controller 21 reporting base stations.
Step S204: service wireless network controller 21 is measured request to the 22 times signalling angles of arrival in base station.The signal angle of arrival is measured in the request and is represented the signal that needs are measured with dedicated channel mark mark, because relevant configuration information has been stored in base station 22 when setting up this dedicated channel before this, so base station 22 can be measured on corresponding Radio Resource, obtains effective measurement result.
Step S205: the relevant measurement carried out in base station 22.
Step S206: base station 22 reports the signal angle of arrival to measure to service wireless network controller 21.
Step S207: service wireless network controller 21 carries out position calculation.
Step S208: service wireless network controller 21 reports the location estimation result to core net 20.
In real system, for needing at least two base stations, the position of measuring mobile phone 23 participates in, and one of them base station is the serving BS that exists wireless signaling to be connected with mobile phone, other assistant base stations for not existing wireless signaling to connect.Serving BS has the configuring condition information of mobile phone upward signal owing to the channel configuration signaling.There are not at present means to obtain the configuring condition information of mobile phone upward signal as yet for assistant base station.Assistant base station can't carry out corresponding mobile phone arrival angular surveying under these circumstances, thereby can't finish location tasks.Therefore need other information auxiliary, for example serving BS signal Loop Round Trip Time or serving BS and assistant base station downstream signal arrive the time difference of mobile phone, to finish location work.The acquisition of these supplementarys has increased the complexity of measuring, and has reduced the efficient of location.
