detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

It should be noted that the terminals described in the following embodiments all designate the positioning target terminal. The measurement equipment described in the following embodiments includes a positioning target terminal and a base station.

FIG. 1 is a schematic flowchart of a method for triggering positioning measurement provided by an embodiment of the present invention. As shown in FIG. 1 , the method for triggering positioning measurement in this embodiment may include:

101. The measurement device receives a positioning request sent by a positioning server, where the positioning request includes a positioning type and a trigger reporting criterion, and the trigger reporting criterion includes a measurement quantity change event, a secondary cell change event, a motion state change event, and an environment change event at least one.

For example, the duration of the positioning service demand is very long, and the positioning accuracy is required to be moderate. It is necessary to consider not only the accuracy, but also the energy saving of the measurement equipment. The energy consumption and network overhead of the measurement equipment are easy to increase due to the periodic trigger report.

In order to save the energy consumption and network overhead of the measurement equipment, in an optional embodiment of the present invention, an event-triggered mode, such as the E-CID positioning method, can be used. At this time, the positioning request sent by the positioning server to the measurement equipment includes a positioning The type is E-CID positioning.

It should be noted that, when the positioning type is E-CID positioning, the measurement device may be a base station or a terminal.

Wherein, the triggering reporting criterion is the triggering reporting criterion determined by the positioning server according to the Quality of Service (QoS) of the positioning service; or the triggering reporting criterion is the triggering reporting criterion determined by the positioning server according to the self-capability information sent by the terminal, wherein the terminal itself The capability information includes at least one of carrier aggregation capability, capability of measuring terminal motion state, radio frequency identification capability or near field communication capability.

In an optional implementation manner of the present invention, when the terminal does not report the above capability information to the positioning server, or the terminal does not have the above capability information, the positioning server may determine the trigger reporting criterion according to the service quality of the positioning service. The trigger reporting criterion includes a measurement quantity change event, through which a threshold value of measurement quantity change can be preset.

Wherein, when the measurement device is a terminal, the change in the measurement quantity includes a change in the reference signal received power (Reference Signal Received Power, RSRP) and/or a change in the terminal sending and receiving time difference (Ue Rx-Tx time difference) and/or the measured Changes in the precoding matrix index (ProcodeMatrix Index, PMI);

Here, the terminal obtains the change of RSRP, wherein the RSRP refers to the RSRP value of the reference signal generated by the base station of the primary cell detected by the terminal. The RSRP reported in terminal location is the value of RSRP in maintaining mobility management. The RSRP change means that the difference between the last reported RSRP and the latest mobility management RSRP is greater than a preset threshold.

The terminal transmit and receive time difference (Ue Rx-Tx time difference) is the timing difference between the uplink subframe and the downlink subframe measured by the terminal. The change in the terminal sending and receiving time difference means that the terminal detects that the change in the timing difference between the uplink subframe and the downlink subframe in the last positioning report and the timing difference between the uplink subframe and the downlink subframe in this subframe is greater than the preset threshold.

When the measurement device is a base station, the change of the measurement amount includes the change of the RSRP of the primary cell and/or the change of the uplink timing advance (Time Advance, TA), and or the change of the base station transceiver time difference and/or the angle of arrival (Angle of Arrival, AOA) changes;

Here, the base station obtains the change of RSRP, wherein the RSRP refers to the RSRP value of the reference signal generated by the base station of the main cell detected by the terminal, and is reported and obtained when maintaining the mobility management of the terminal. The RSRP change means that the difference between the last reported RSRP and the latest mobility management RSRP is greater than a preset threshold.

Wherein, the uplink timing advance TA includes a first type (type 1) uplink timing advance and/or a second type (type 2) uplink timing advance.

Among them, the first type (type 1) uplink timing advances the sum of the eNB transceiver time difference measured by the base station plus the terminal measurement to the terminal transceiver time difference:

TADV=(eNB Rx–Tx time difference)+(UE Rx–Tx time difference);

The UE Rx–Tx time difference is reported by the terminal to the base station. The first type of uplink timing advance change means that the change between the first type (type 1) uplink timing advance reported by the base station last time and the first type (type 1) uplink timing advance obtained in this frame exceeds the predetermined threshold.

The second type (type 2) uplink timing advance: TADV=(eNB Rx–Tx timedifference);

The base station transmits and receives the time difference measured by the base station based on the transmission of wireless frames in the physical random access channel (Physical Random Access CHannel, PRACH) channel of the terminal.

The second type of uplink timing advance change means that the change between the second type (type 2) uplink timing advance reported by the base station last time and the second type (type 2) uplink timing advance obtained in this frame exceeds the predetermined threshold.

In an optional embodiment of the present invention, when the terminal has at least one capability including carrier aggregation capability, capability of measuring terminal motion state, radio frequency identification capability or near field communication capability, the terminal can report to the positioning server For the capability information of the terminal itself, the positioning server may determine a triggering reporting criterion according to the reported capability information.

Wherein, the trigger reporting criterion includes at least one of a secondary cell change event, a motion state change event, and an environment change event. Specifically, the secondary cell change of the terminal can be preset in the secondary cell change event, the environment in which the terminal leaves or enters can be preset in the environment change event, and the movement of the terminal can be preset in the motion state change event state.

It should be noted that, the preset secondary cell change in this embodiment includes, for example, adding an activated secondary cell, releasing a secondary cell, adding a configured secondary cell, or deactivating a secondary cell; When the secondary cell is a cell, the RSRP of the newly configured secondary cell is higher than the preset threshold; when the secondary cell is changed to the deactivated secondary cell, the RSRP of the deactivated secondary cell is lower than the preset threshold.

102. When detecting at least one event trigger in the trigger reporting criteria, the measurement device generates a positioning measurement report of the positioning type, and sends the positioning measurement report of the positioning type to the positioning server.

In an optional implementation manner of the present invention, when the measurement device is a base station or a terminal, step 102 specifically includes:

When the measurement device monitors that the measurement quantity change exceeds the preset measurement quantity change threshold value in the measurement quantity change event, it can trigger the sending of the positioning measurement report of the E-CID positioning to the positioning server. During specific implementation:

For example, the change between the last reported RSRP measurement result of the primary cell of the terminal and the currently reported RSRP measurement result exceeds the preset RSRP change threshold; or

When the terminal has the carrier aggregation capability, the change between the last reported RSRP measurement result of the terminal's secondary cell and the currently reported RSRP measurement result exceeds a preset RSRP change threshold.

Among them, RSRP corresponds to the change of the path loss (PathLoss, PL). The path loss can be expressed as the relationship between the carrier frequency and the distance. ΔRSRP>th1 can reflect the change of the distance between the terminal and the base station of the cell; of Sight), when the carrier frequency is 2GHz, the path loss model is PL(R)=103.4+24.2log10(R), R represents the distance between the terminal and the base station of the cell, in kilometers, then when ΔRSRP>th1, the corresponding distance R1 , The ratio of R2 can represent R1/R2=10^(th1/24.2), that is, if ΔRSRP>th1=24.2*0.3, R1/R2=2, which means that the distance between the terminal and the cell base station has changed by 2 times.

For another example, the change between the Ue Rx-Tx time difference reported last time by the primary cell of the terminal and the currently reported terminal sending and receiving time difference exceeds the preset terminal receiving and sending time difference change threshold; or when the terminal has carrier aggregation capabilities , the change between the terminal sending and receiving time difference reported last time by the secondary cell of the terminal and the terminal sending and receiving time difference currently reported exceeds a preset terminal sending and receiving time difference change threshold.

Among them, the terminal transceiver time difference represents the downlink timing and uplink timing difference of the terminal, which can reflect the change of the distance between the terminal and the base station of the cell. The distance between the terminal and the base station of the cell is d=c*(Ue Rx-Txtime difference)/2, where c is the speed of light ; In the Long Term Evolution (LTE) system, the unit of Ue Rx-Tx time difference is Ts=1/(30.72*10^6)s, when ΔUe Rx-Tx time difference=2Ts, about terminal and The distance between cell base stations varies by 10 meters.

For another example, the change of the precoding matrix index (Procode Matrix Index, PMI) reported by the terminal's main cell last time when the terminal reported positioning measurement and the PMI reported by the current terminal exceeds the preset PMI change threshold;

The PMI divides the space into beams of several angle ranges of the antenna, for example, 8 antennas, and each PMI corresponds to beams of 360°/8 angle ranges. Assuming that the PMI was #1 when the measurement was reported last time, and the PMI measured by the terminal this time is #2, and the preset threshold is a difference of 1 PMI index, then a PMI change event is detected by the terminal this time.

For another example, the RSRP change of the terminal monitored by the base station exceeds a preset threshold;

The base station needs to collect the RSRP value measured by the terminal when maintaining the mobility management. When the base station detects that the change of the RSRP of the terminal exceeds the threshold. That is, the change between the terminal RSRP reported by the last positioning and the terminal RSRP detected this time exceeds the budget threshold.

For another example, the change of the angle of arrival (AOA) of the terminal signal measured by the base station exceeds the preset threshold, wherein the base station measures the difference between the signal angle of arrival of the terminal reported by the last positioning and the signal angle of arrival of the terminal measured this time. The change exceeds the preset threshold.

Similar base stations can also trigger measurements according to changes in PMI reported by terminals.

Or the change of the uplink advance amount (Time Advance, TA) of the terminal measured by the base station exceeds a preset threshold.

Wherein the first type of TA has the terminal sending and receiving time difference reported by the terminal, which is measured and reported by the terminal to the base station. The base station monitors the change of the first type TA.

The second type of TA is measured on the PRACH channel, and the terminal monitors the change of the second type of TA.

Among them, the uplink advance amount TA can reflect the change of the distance between the terminal and the base station of the primary cell or the base station of the secondary cell; the distance between the terminal and the base station of the primary cell or the base station of the secondary cell is d=c*(TA)/2, where c is the speed of light , in the LTE system, the unit of TA is Ts=1/(30.72*10^6)s, when ΔTA=2Ts, the distance between the terminal and the base station of the primary cell or the base station of the secondary cell changes by about 10 meters; among them, the signal Changes in the angle of arrival AOA or PMI can also reflect the orientation of the terminal in the base station of the primary cell or the secondary cell.

In an optional embodiment of the present invention, when the measurement device is a base station or a terminal, the specific implementation of step 102 includes:

When the measurement device detects that the change of the secondary cell conforms to the preset change of the secondary cell in the change event of the secondary cell, it can trigger sending a positioning measurement report of E-CID positioning to the positioning server.

For example, when the terminal is in a carrier aggregation (Carrier Aggregation, CA) scenario, the terminal may be in the service range of a primary cell (PC) and multiple secondary cells (Secondary Cell, SC). The coverage area is usually smaller than the corresponding coverage area of the primary cell, and can more accurately reflect the location of the terminal.

When the secondary cell is changed to a newly configured secondary cell, and the RSRP of the newly configured secondary cell is higher than the threshold, specifically, the configuration of the secondary cell can be configured by sending radio resource control (Radio Recourse Control, RRC) signaling by the base station , the RRC signaling is carried by an RRC reconfiguration (RRC Connection Reconfiguration) message. Wherein, the newly configured secondary cell means that the base station wishes to schedule the secondary cell for the terminal, but the terminal needs to further confirm whether to activate the secondary cell. If the RSRP measured by the terminal is relatively high, it indicates that the terminal belongs to the coverage of the secondary cell, and the coverage of the secondary cell can be used to further limit the location of the terminal.

When the secondary cell is changed to a newly activated secondary cell, activation of the secondary cell may be implemented by sending a medium access control (Medium Access Control, MAC) signaling activation mode from the base station. Wherein, the newly activated secondary cell indicates that the terminal is within the coverage of the secondary cell, which can reflect the position of the terminal more accurately than the coverage of the primary cell.

When the secondary cell is changed and the secondary cell is released or deactivated, and the RSRP corresponding to the released secondary cell is lower than the threshold; wherein, the release or deactivation of the secondary cell includes two situations, one is that the location of the terminal has moved and no longer The service suitable for the secondary cell may be that the service of the terminal has changed and the secondary cell no longer needs to provide services. Specifically, the result of RSRP measurement can be used to judge. If the terminal has moved, the RSRP measurement value corresponding to the secondary cell is lower than the preset threshold, indicating that the terminal is leaving the coverage area of the secondary cell.

When the secondary cell is changed to a deactivated secondary cell, and the RSRP of the deactivated secondary cell is lower than the preset threshold, specifically, the deactivation of the secondary cell can be realized by sending a medium access control (Medium Access Control, MAC) signaling activation by the base station. district.

In an optional embodiment of the present invention, when the measuring device is a terminal, the specific implementation of step 102 may also include:

When the measurement device (terminal) monitors that it leaves or enters the preset environment in the environment change event, it can trigger the sending of the positioning measurement report of the E-CID positioning to the positioning server;
