Need to prove that the default auxilliary cell change of present embodiment for example comprises that increasing activation newly assists the residential quarter, discharges auxilliary residential quarter, increases newly to dispose and assist residential quarter or the auxilliary residential quarter of deexcitation; When described auxilliary cell change was the auxilliary residential quarter of described newly-increased configuration, then the RSRP of the auxilliary residential quarter of described newly-increased configuration was higher than default thresholding; When described auxilliary cell change is the auxilliary residential quarter of described deexcitation, then the RSRP of the auxilliary residential quarter of described deexcitation is lower than default thresholding.
102, measuring equipment monitors described triggering when reporting in the criterion at least one Event triggered, generates the location survey report of described align_type, and the location survey report of described align_type is sent to described location-server.
In an optional execution mode of the present invention, when measuring equipment was base station or terminal, step 102 specifically comprised:
When measuring equipment monitors measuring amount when change surpassing measuring amount default in the described measuring amount change events and changing threshold value, the location survey report that can trigger the E-CID location sends to described location-server, during specific implementation:
For example, the RSRP measurement result that reported last time of the main plot of terminal and the variation between the current RSRP measurement result that reports surpass default RSRP and change thresholding; Perhaps
When terminal has the carrier aggregation of comprising ability, the RSRP measurement result that the auxilliary residential quarter of terminal reported last time and the variation between the current RSRP measurement result that reports surpass default RSRP and change thresholding.
Wherein, the RSRP correspondence be path loss (path loss can be expressed as the relation of carrier frequency and distance for PathLoss, variation PL), Δ RSRP〉th1, can reflect the variation of distance between terminal and cell base station; Such as there being sighting distance (LOS Light of Sight), when carrier frequency is 2GHz, the path loss model is PL (R)=103.4+24.2log10 (R), and R represents distance between terminal and cell base station, the unit km, then as Δ RSRP〉th1, corresponding distance R 1, the ratio of R2 can be represented R1/R2=10^ (th1/24.2), that is to say, if Δ RSRP〉during th1=24.2*0.3, R1/R2=2, distance has changed 2 times between expression terminal and cell base station.
Again for example, terminal transmitting-receiving time difference (Ue Rx-Tx time difference) of reporting last time of the main plot of terminal and the current variation of terminal between the transmitting-receiving time difference that reports surpass the default terminal transmitting-receiving time difference and change thresholding; Perhaps have the carrier aggregation of comprising ability when terminal, the terminal transmitting-receiving time difference that the auxilliary residential quarter of terminal reported last time and the current variation of terminal between the transmitting-receiving time difference that reports surpass the default terminal transmitting-receiving time difference and change thresholding.
Wherein, descending timing and the up timing difference of terminal represented in the terminal transmitting-receiving time difference, can reflect the variation of distance between terminal and cell base station, between terminal and cell base station apart from d=c*(Ue Rx-Tx time difference)/2, wherein c is the light velocity; At Long Term Evolution (Long Term Evolution, LTE) in the system, the unit of Ue Rx-Tx time difference is Ts=1/ (30.72*10^6) s, when Δ Ue Rx-Tx time difference=2Ts, approximately between terminal and cell base station the variation of distance 10 meters.
Again for example, the pre-coding matrix index during terminal to report location survey that the main plot of terminal reported last time (Procode Matrix Index, PMI) and the PMI of current terminal to report change and surpass default PMI and change thresholding;
PMI is divided into the wave beam of several angular ranges of antenna with the space, is example as 8 antennas, and each PMI is for the wave beam of 360 °/8 angular range.Suppose last time reporting measurement the time PMI be #1, and the PMI that measures in this terminal is #2, default thresholding is to differ 1 PMI index, monitors the PMI change events in this terminal so.
Again for example, the terminal RSRP that arrives of base station monitors changes and surpasses default thresholding;
The RSRP value that the base station needs collection terminal to measure when safeguarding mobile management changes above thresholding when the base station detects terminal RSRP.Be last time terminal RSRP and the terminal RSRP of this detection of locating reporting change and surpass the budget thresholding.
Again for example, the signal angle of arrival of the terminal of base station measurement (Angle of Arrival, AOA) change to surpass default thresholding, wherein, base station measurement to last time locating reporting the signal angle of arrival of terminal and the variation of the signal angle of arrival of the terminal of this measurement surpass default thresholding.
Similarly the base station also can change to trigger measurement according to the PMI of terminal to report.
Or the up lead of the terminal of base station measurement (Time Advance TA) change to surpass default thresholding.
The terminal transmitting-receiving time difference of terminal to report is wherein arranged among the first kind TA, report the base station by the terminal measurement.The variation of base station monitoring first kind TA.
And the second type TA measures at the PRACH channel, and the TA of terminal monitoring second type changes.
Wherein, up lead TA can reflect the variation of distance between terminal and base station, main plot or the auxilliary cell base station; Between terminal and base station, main plot or the auxilliary cell base station apart from d=c*(TA)/2, wherein c is the light velocity, and in the LTE system, the unit of TA is Ts=1/ (30.72*10^6) s, as Δ TA=2Ts, approximately the variable in distance between terminal and base station, main plot or the auxilliary cell base station 10 meters; Wherein, the angle of arrival AOA of signal or PMI variation can reflect that also terminal is in the orientation of base station, main plot or auxilliary residential quarter.
In an optional execution mode of the present invention, when measuring equipment is base station or terminal, comprise during step 102 specific implementation:
When measuring equipment monitors auxilliary cell change when meeting auxilliary cell change default in the described auxilliary cell change event, the location survey report that can trigger the E-CID location sends to described location-server.
For instance, when terminal is in carrier aggregation (Carrier Aggregation, CA) in the scene, this terminal may be in a main plot (Primary Cell, PC) and a plurality of auxilliary residential quarter (Secondary Cell, SC) service range since the coverage of auxilliary residential quarter correspondence the coverage than main plot correspondence is little usually, position that can more accurate reflection terminal.
When auxilliary cell change is assisted the residential quarter for newly-increased configuration, and the RSRP of the auxilliary residential quarter of described newly-increased configuration is higher than thresholding, particularly, auxilliary cell configuration can send Radio Resource control (Radio Recourse Control by the base station, RRC) signaling configuration, this RRC signaling is to reshuffle (RRC Connection Reconfiguration) message by RRC to carry.Wherein, the auxilliary residential quarter of newly-increased configuration is that wish to the auxilliary residential quarter of this terminal scheduling the base station, but also needs the further affirmation of terminal whether to activate this auxilliary residential quarter.If the RSRP that terminal is measured is higher, show that then this terminal belongs in the coverage of this auxilliary residential quarter, can further limit the position of terminal with the coverage of this auxilliary residential quarter.
When auxilliary cell change activates auxilliary residential quarter for newly-increased, (Medium Access Control, MAC) mode that activates of signaling realizes activating auxilliary residential quarter can to send media interviews control by the base station.Wherein, the auxilliary residential quarter of newly-increased activation shows terminal in the coverage of this auxilliary residential quarter, can be than the position of the more accurate reflection terminal of main plot coverage.
When auxilliary cell change discharges or during the auxilliary residential quarter of deexcitation, and the RSRP of the auxilliary residential quarter correspondence of described release is lower than thresholding; Wherein, discharge or the auxilliary residential quarter of deexcitation comprises two kinds of situations, a kind of is that has moved the position of terminal, no longer is fit to the service of this auxilliary residential quarter, and a kind of is that variation has taken place for the business of this terminal, no longer needs auxilliary residential quarter that service is provided.The result that specifically can adopt RSRP to measure judges, if the terminal shift position, RSRP measured value that then should auxilliary residential quarter correspondence is lower than default thresholding, shows that this terminal just leaving the overlay area of this auxilliary residential quarter.
Be the auxilliary residential quarter of deexcitation when stating auxilliary cell change, and the RSRP of the auxilliary residential quarter of described deexcitation is lower than default thresholding, (Medium Access Control, MAC) mode that activates of signaling realizes that deexcitation assists the residential quarter specifically can to send media interviews control by the base station.
