Wherein the change of Second Type up timing advance, refers to that base station reported the Equations of The Second Kind of location in last time Second Type (type 2) the up timing that type (type 2) up timing advance and this frame obtain carries Front varies more than reservation thresholding.

In an optional embodiment of the present invention, include carrier aggregation capacity, survey when terminal has At least one in the amount ability of motion state of terminal, radio frequency identification ability or near field communications capability During ability, this terminal can report the ability information of this terminal self, positioning service to location-server According to the ability information reported, device can determine that triggering reports criterion.

Wherein, triggering reports criterion to include secondary cell change events, kinestate change events, ring At least one in the change events of border.Specifically, by described secondary cell change events can be preset The secondary cell change of terminal, by presetting what terminal was left or entered in described environment change event Environment, by presetting the kinestate of terminal in described kinestate change events.

It should be noted that the secondary cell change that the present embodiment is preset such as includes that newly-increased activation is auxiliary little District, release secondary cell, newly-increased configuration secondary cell or deexcitation secondary cell；When described secondary cell is changed to During described newly-increased configuration secondary cell, the RSRP of the most described newly-increased configuration secondary cell is higher than pre-determined threshold； When described secondary cell is changed to described deexcitation secondary cell, and the RSRP of the most described deexcitation secondary cell is low In pre-determined threshold.

102, measure monitoring of equipment to described triggering report in criterion at least one event to trigger time, raw Become the location measurement report of described align_type, and the location measurement report of described align_type is sent To described location-server.

In an optional embodiment of the present invention, when measurement equipment is base station or terminal, step 102 specifically include:

The survey preset in described measurement amount change events is varied more than to measurement amount when measuring monitoring of equipment Amount amount change threshold value time, can trigger by E-CID position location measurement report be sent to described fixed Position server, when implementing:

Such as, the main plot of terminal reported last time RSRP measurement result and the RSRP currently reported The default RSRP that varies more than between measurement result changes thresholding；Or

Including carrier aggregation capacity when terminal has, the RSRP that the secondary cell of terminal reported last time measures The default RSRP that varies more than between result and the RSRP measurement result currently reported changes door Limit.

Wherein, what RSRP was corresponding is the change of path loss (PathLoss, PL), and path loss can represent For the relation of carrier frequency Yu distance, Δ RSRP > th1, terminal and cell base station spacing can be reflected Change；Such as there is sighting distance (LOS Light of Sight), when carrier frequency is 2GHz, road Damage model is PL (R)=103.4+24.2log10 (R), and R represents terminal and cell base station spacing, single Position km, then as Δ RSRP > th1, corresponding distance R1, the ratio of R2 can represent R1/R2=10^ (th1/24.2), say, that if during Δ RSRP > th1=24.2*0.3, R1/R2=2, Represent that terminal and cell base station spacing have changed 2 times.

The most such as, terminal transmitting-receiving time difference (the Ue Rx-Tx time that the main plot of terminal reported last time Difference) the default terminal that varies more than between the terminal transmitting-receiving time difference and currently reported is received and dispatched Time difference change thresholding；Or include carrier aggregation capacity when terminal has, the secondary cell last time of terminal Varying more than between the terminal transmitting-receiving time difference and the terminal transmitting-receiving time difference currently reported that report is pre- If terminal transmitting-receiving time difference change thresholding.

Wherein, terminal transmitting-receiving time difference represents the descending timing of terminal and up timing difference, can reflect Terminal and the change of cell base station spacing, terminal and cell base station spacing d=c*(Ue Rx-Tx Time difference)/2, wherein c is the light velocity；Long Term Evolution (Long Term Evolution, LTE), in system, the unit of Ue Rx-Tx time difference is Ts=1/ (30.72*10^6) s, when During Δ Ue Rx-Tx time difference=2Ts, about terminal and the change of cell base station spacing 10 meters.

The most such as, the pre-coding matrix when terminal to report location that the main plot of terminal reported last time is measured The PMI that index (Procode Matrix Index, PMI) and present terminal report varies more than default PMI change thresholding；

Space is divided into the wave beam of the several angular range of antenna by PMI, as a example by 8 antennas, each PMI for 360 °/8 the wave beam of angular range.Assume that the when of reporting measurement last time, PMI is #1, And the PMI measured in this terminal is #2, pre-determined threshold is 1 PMI index of difference, then This terminal monitoring is to PMI change events.

The most such as, base station monitors to terminal RSRP vary more than pre-determined threshold；

Base station needs the RSRP value that collection terminal is measured when safeguarding mobile management, when base station is detected Thresholding is varied more than to terminal RSRP.I.e. terminal RSRP of locating reporting last time and this detection Terminal RSRP varies more than budget thresholding.

The most such as, the direction of arrival (Angle of Arrival, AOA) of the terminal of base station measurement becomes Change exceed pre-determined threshold, wherein, the direction of arrival of base station measurement to the terminal of locating reporting last time and This measure terminal direction of arrival vary more than pre-determined threshold.

Similar base station can also change according to the PMI of terminal to report triggers measurement.

Or the up lead (Time Advance, TA) of the terminal of base station measurement varies more than default Thresholding.

First kind TA wherein has the terminal transmitting-receiving time difference of terminal to report, by terminal measurement report To base station.The change of base station monitoring first kind TA.

And Second Type TA measures on PRACH channel, the TA of terminal monitoring Second Type Change.

Wherein, up lead TA can reflect between terminal and base station, main plot or secondary cell base station The change of distance；Distance d=c*(TA between terminal and base station, main plot or secondary cell base station)/2, Wherein c is the light velocity, and in LTE system, the unit of TA is Ts=1/ (30.72*10^6) s, when Distance between Δ TA=2Ts, about terminal and main plot base station or secondary cell base station has changed 10 meters； Wherein, arrival angle AOA or the PMI change of signal also can reflect that terminal is in base station, main plot or auxiliary The orientation of community.

In an optional embodiment of the present invention, when measurement equipment is base station or terminal, step 102 include when implementing:

When measure monitoring of equipment to secondary cell change meet in described secondary cell change events preset auxiliary During cell change, the location measurement report by E-CID positions can be triggered and be sent to described positioning service Device.

For example, in terminal is in carrier aggregation (Carrier Aggregation, CA) scene, This terminal is likely to be at a main plot (Primary Cell, PC) and multiple secondary cell (Secondary Cell, SC) service area, the coverage corresponding due to secondary cell is generally corresponding than main plot Coverage is little, it is possible to reflect the position of terminal more accurately.

When secondary cell is changed to newly-increased configuration secondary cell, and the secondary cell of described newly-increased configuration RSRP is higher than thresholding, and specifically, secondary cell configuration can send wireless heterogeneous networks by base station (Radio Recourse Control, RRC) signal deployment, this RRC signaling is by RRC weight Configuration (RRC Connection Reconfiguration) message is carried.Wherein, newly-increased configuration is auxiliary Community is that base station is intended to this terminal scheduling secondary cell, but also needs to terminal further confirms that whether activate This secondary cell.If the RSRP that terminal is measured is higher, then show that this terminal belongs to covering of this secondary cell In the range of lid, the position of terminal can be limited further by the coverage of this secondary cell.

When secondary cell is changed to newly-increased activation secondary cell, media interviews can be sent by base station and control The mode that (Medium Access Control, MAC) signaling activates realizes activating secondary cell.Wherein, The newly-increased secondary cell that activates shows that terminal, in the coverage of this secondary cell, can cover model than main plot Enclose the position reflecting terminal more accurately.

When secondary cell change release or deexcitation secondary cell, and the secondary cell of described release is corresponding RSRP is less than thresholding；Wherein, release or deexcitation secondary cell include two kinds of situations, and one is terminal Position move, be no longer appropriate for the service of this secondary cell, a kind of is that the business of this terminal there occurs change Change, it is no longer necessary to secondary cell provides service.The result that specifically RSRP can be used to measure judges, If terminal shift position, then the RSRP measured value that this secondary cell is corresponding is less than pre-determined threshold, Show that this terminal is just leaving the overlay area of this secondary cell.

It is changed to deexcitation secondary cell when stating secondary cell, and the RSRP of described deexcitation secondary cell is less than pre- If thresholding, specifically can be controlled by base station transmission media interviews (Medium Access Control, MAC) mode that signaling activates realizes deexcitation secondary cell.

In an optional embodiment of the present invention, when measurement equipment is terminal, step 102 has Can also include when body realizes:

When measure equipment (terminal) monitor self leave or enter in described environment change event preset During environment, the location measurement report by E-CID positions can be triggered and be sent to described location-server；
