Step 0, the access network device of the cell where the UE resides, the access network device of the cell where the UE neighbors, and the positioning management function entity (English: location Management Function; LMF for short) exchange PRS Configuration information (English: NRPPA DL PRS Configuration).

It should be noted that, in the embodiment of the present application, the access network device may be a transmission receiving node (english: transmission reception point, abbreviated as TRP), a base station, a relay station, or an access point, and the access network device may be an access network device in a 5G communication system, for example, a gNB.

The PRS configuration information may include, for example, a time-frequency location of a communication resource carrying PRS, a transmission period of PRS, and the like, and the embodiment of the present application does not limit specific content of the PRS configuration information.

Step 1, the UE, the access network equipment of the cell where the UE resides, the access network equipment of the cell adjacent to the UE and the LMF exchange the LTE positioning protocol (LPP for short) capability with each other.

And step 2, the LMF sends a positioning information request (English: NRPPa Positioning Information Request) to the access network equipment of the cell where the UE resides.

Step 3, the access network device of the cell where the UE resides decides the time-frequency position of the communication resource carrying the uplink channel Sounding REFERENCE SIGNAL (SRS for short).

Step 3a, the access network equipment of the cell where the UE resides sends SRS configuration information to the UE.

The SRS configuration information may include, for example, a time-frequency location of a communication resource carrying the SRS, a transmission period of the SRS, and the like, and the specific content of the SRS configuration information is not limited in the embodiment of the present application.

And 4, the access network equipment of the cell where the UE resides sends a positioning information response (English: NRPPa Positioning Information Response) to the LMF.

Wherein the positioning information response carries SRS configuration information.

Step 5a, LMF sends location activation request (English: NRPPa Positioning Activation Request) to access network equipment of cell where UE resides.

And 5b, the access network equipment of the cell where the UE resides activates the UE to transmit SRS.

And 5c, the access network equipment of the cell where the UE resides sends a positioning activation response (English: NRPPa Positioning Activation Response) to the LMF.

And 6, the LMF sends a measurement request to the access network equipment of the cell where the UE resides (English: NRPPa Measurement Request) to the access network equipment of the UE neighbor cell.

Wherein, the measurement request carries SRS configuration information.

Step 7, the LMF transmits LPP assistance data (english: LPP provider ASSISTANCE DATA) to the UE.

The LPP assistance data includes PRS configuration information of access network equipment of a UE resident cell and PRS configuration information of access network equipment of a UE neighbor cell.

Step 8, LMF sends LPP request position information (English: LPP Request Location Information) to UE.

And 9a, the UE measures PRS sent by the access network equipment of the cell where the UE resides and the access network equipment of the neighboring cell of the UE.

And 9b, the access network equipment of the cell where the UE resides measures the SRS sent by the UE by the access network equipment of the cell adjacent to the UE.

Step 10, the UE transmits LPP providing position information (English: LPP Provide Location Information) to the LMF.

And 11, the access network equipment of the cell where the UE resides and the access network equipment of the cell adjacent to the UE send a measurement response to the LMF (English: NRPPa Measurement Response).

Step 12, the LMF sends positioning deactivation information (English: NRPPa Positioning Deactivation) to the access network equipment of the cell where the UE resides.

It should be noted that, the positioning process shown in fig. 1 is a positioning process related to a multi Round Trip Time (english: multi RTT) positioning technology.

In the positioning procedure shown in fig. 1, the LMF needs to send PRS configuration information of the access network device of the UE residence cell and PRS configuration information of the access network device of the UE neighbor cell to the UE in step 7, the UE needs to measure PRS sent by the access network device of the UE residence cell and the access network device of the UE neighbor cell according to the received PRS configuration information (step 9 a), so as to obtain a first timestamp of PRS sent by the access network device of the UE residence cell and a second timestamp of PRS sent by the access network device of the UE neighbor cell, besides which the UE may also obtain a third timestamp of SRS sent by the UE itself, and the UE may report a difference between the first timestamp and the third timestamp and a difference between the second timestamp and the third timestamp to the LMF (step 10).

Meanwhile, the LMF needs to send the SRS configuration information to the access network device of the UE residence cell and the access network device of the UE neighbor cell in step 6, the access network device of the UE residence cell and the access network device of the UE neighbor cell need to measure the SRS sent by the UE according to the SRS configuration information (step 9 b), by measuring, the access network device of the UE residence cell can obtain the fourth timestamp of the detected SRS, the access network device of the UE neighbor cell can obtain the fifth timestamp of the detected SRS, in addition, the access network device of the UE residence cell can also obtain the sixth timestamp of the PRS sent by itself, the access network device of the UE neighbor cell can also obtain the seventh timestamp of the PRS sent by itself, the access network device of the UE residence cell can report the difference between the fourth timestamp and the sixth timestamp to the LMF (step 11), and the access network device of the UE neighbor cell can report the difference between the fifth timestamp and the seventh timestamp to the LMF (step 11).

Referring to fig. 2, the lmf may take the sum of the difference between the first time stamp and the third time stamp and the difference between the fourth time stamp and the sixth time stamp as an RTT between the UE and the access network device of the UE-camping cell, and estimate a distance between the UE and the access network device of the UE-camping cell based on the calculated RTT.

In addition, the LMF may further use the sum of the difference between the second timestamp and the third timestamp and the difference between the fifth timestamp and the seventh timestamp as an RTT between the UE and the access network device of the UE neighboring cell, and estimate a distance between the UE and the access network device of the UE neighboring cell based on the calculated RTT.

Under the condition that the number of the access network equipment of the cell where the UE resides and the number of the access network equipment of the cell where the UE resides are at least 3, the LMF can estimate the position of the UE based on a triangulation method by utilizing the distance between the UE and the access network equipment of the cell where the UE resides and the distance between the UE and the access network equipment of the cell where the UE resides. Wherein fig. 3 is a schematic diagram of the principle of triangulation.

From the foregoing, it can be seen that the measurement of PRS by the UE greatly affects the positioning accuracy of the UE, however, since the transmission of PRS is affected by the signal transmission environment of the communication network, the positioning of the UE is often inaccurate when the signal transmission environment is worse.

In view of this, an embodiment of the present application provides a configuration modification method, an apparatus, a communication device, and a storage medium, where in the configuration modification method, a UE may receive a configuration modification trigger condition sent by a network side device, and send a configuration change request to the network side device when a measurement result obtained by measuring a received PRS meets the configuration modification trigger condition, so as to instruct the network side device to modify at least one of a configuration of the PRS and a configuration of an access network device that sends the PRS to the UE, and by modifying the configuration, a transmission quality of the PRS may be improved when a signal transmission environment is worse, thereby improving positioning accuracy of the UE.

Referring to fig. 4, a schematic diagram of an implementation environment related to a configuration change method provided by an embodiment of the present application is shown in fig. 4, where the implementation environment includes a UE401, an access network device 402 where the UE401 resides in a cell, an access network device 403 where the UE401 is adjacent to the cell, and a network side device 404, where the network side device 404 may be an LMF.

As described above, access network device 402 and access network device 403 may each transmit PRSs to UE401 in accordance with their respective current PRS configurations, and UE401 may measure PRSs transmitted by access network device 402 and access network device 403.

In order to achieve triangulation, the number of access network devices 402 and 403 is at least 3 in the embodiment of the present application.

Among other things, UE401 may include a PDA (chinese: personal digital assistant, english: personal DIGITAL ASSISTANT), a handheld device with wireless communication capability, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a user device in a 5G network or a user device in a future evolved PLMN (chinese: public land mobile network, english: public land mobile network) network, etc.

The access network device 402 and the access network device 403 may be TRP, a base station, a relay station, an access point, or the like, and the access network device may be an access network device in a 5G communication system or an access network device in a future evolution network, may also be a wearable device or an in-vehicle device, or the like, and may also be: BTS (Chinese: base transceiver station, english: base transceiver station) in GSM or CDMA network, NB (NodeB) in WCDMA, eNB or eNodeB (English: evolutional NodeB) in LTE, and access network equipment as well as radio controller in CRAN scene.

Referring to fig. 5, a flowchart of a configuration change method according to an embodiment of the present application is shown, where the configuration change method is applied to the UE401 shown in fig. 4, and as shown in fig. 5, the configuration change method includes the following steps:

Step 501, the UE receives a configuration change trigger condition sent by the network device.

In an alternative embodiment of the present application, the network side device may be an LMF.

In an alternative embodiment of the present application, the network side device may send the configuration change trigger condition for the final positioning result of the UE, or may send the configuration change trigger condition for each PRS transmission link separately.

In the case that the configuration change trigger conditions are sent for each PRS transmission link respectively, the configuration change trigger conditions corresponding to each PRS transmission link may be completely consistent, may be partially consistent, or may not be completely consistent.

Step 502, if a measurement result obtained by measuring the received PRS meets a configuration change trigger condition, the UE sends a configuration change request to a network side device.

In the embodiment of the application, the UE can measure the PRS according to the current PRS configuration of the access network equipment, wherein the measurement Result obtained by the UE for measuring the PRS can comprise a plurality of contents, such as nr-UE-RxTxTimeDiff-r16, nr-DL-PRS-RSRP-Result-r16, nr-DL-PRS-RSRP-ResultDiff-r16, angle and the like, and the embodiment of the application does not limit the specific contents of the measurement Result.

In general, if a measurement result obtained by measuring the PRS meets a configuration change trigger condition, it indicates that a signal transmission environment of a communication network is worse, and in this case, the UE may send a configuration change request to a network side device to instruct the network side device to change at least one of a configuration of the PRS and a configuration of an access network device that sends the PRS to the UE.

Wherein altering the configuration of the PRS includes: changing the time-frequency location of the communication resources carrying PRSs, changing the transmission period of PRSs, etc.

The configuration of the access network device that sends PRS to the UE is further configured to: and replacing all the access network devices which send PRS to the UE with new access network devices, or replacing part of the access network devices which send PRS to the UE with new access network devices, or replacing all the adjacent cell access network devices which send PRS to the UE with new access network devices, or replacing part of the adjacent cell access network devices which send PRS to the UE with new access network devices.

It should be noted that, in the case that the configuration change trigger condition sent by the network side device is a condition for the final positioning result of the UE, the UE may send a configuration change request to the network side device if it is determined, based on the measurement result of the PRS, that the final positioning result satisfies the configuration change trigger condition sent by the network side device.

In this case, the configuration change request may instruct the network-side device to one of:

the access network equipment which sends PRS to UE is replaced by new access network equipment;

Replacing a part of access network equipment which transmits PRS to UE currently with new access network equipment;

all the neighbor cell access network devices which send PRS to the UE are replaced by new access network devices;

Replacing a part of adjacent cell access network equipment which currently sends PRS to UE with new access network equipment;

Changing PRS configuration corresponding to each access network device which sends PRS to UE currently;

Changing PRS configuration corresponding to partial access network equipment which sends PRS to UE currently;

Changing all access network devices which send PRS to UE into new access network devices, and adding corresponding PRS configuration for each new access network device;

changing the access network equipment part which sends PRS to UE to new access network equipment, and adding corresponding PRS configuration for each new access network equipment;

the neighbor cell access network equipment which sends PRS to UE at present is replaced by new access network equipment, and corresponding PRS configuration is added for each new access network equipment;

Replacing a part of adjacent cell access network equipment which sends PRS to UE at present with new access network equipment, and adding corresponding PRS configuration for each new access network equipment;

It should also be noted that, in the case that the network side device sends the configuration change trigger condition for each PRS transmission link to the UE, the UE may send a configuration change request to the network side device if it is determined that a measurement result of a PRS transmission link meets the configuration change trigger condition corresponding to the PRS transmission link.

Changing the access network equipment in the PRS transmission link, the measurement result of which meets the corresponding configuration change triggering condition, into new access network equipment;

changing PRS configuration of PRS transmission links with measurement results meeting corresponding configuration change triggering conditions;

And replacing the access network equipment in the PRS transmission link, the measurement result of which meets the corresponding configuration change triggering condition, with new access network equipment, and adding PRS configuration for the new access network equipment.

In an alternative embodiment of the application, the configuration change trigger condition comprises at least one of:

the positioning integrity does not meet the condition of the positioning integrity index;

a condition occurs that configures a replacement trigger event.

The following will describe the above two conditions, respectively:

1. the positioning integrity does not meet the condition of the positioning integrity index.

In order to facilitate the reader's understanding of the above conditions, embodiments of the present application will briefly describe the concept of positioning integrity as follows:

Location integrity (english) is a measure of the confidence in the accuracy of location-related data provided by a location system (i.e., a communication system in an embodiment of the application) and the ability to provide timely and effective alerts to clients when the location system does not meet the expected operational expectations.

In general, positioning integrity can be measured based on positioning integrity indicators (English: key performance indicator), which typically include warning level (English: ALERT LEVEL; AL for short), alert duration (English: time-to-alert; TTA for short), and target integrity rate (English: TARGET INTEGRITY RATE; TIR for short).

Generally, the UE may calculate the protection level (english: protection level; abbreviated as PL) on the basis of a series of concerns (english: FEARED EVENT) that the positioning system may face, where PL is a statistical upper limit of positioning errors, and generally, the lower the TIR setting, the more FEARED EVENT that needs to be considered in calculating PL.

In practical applications FEARED EVENT can be divided into two categories: fault FEARED EVENT (a concern event due to a fault) and fault-FREE FEARED EVENT (a concern event not due to a fault). FEARED EVENT are events inherent to the positioning system due to faults, typically caused by a fault of some element of the positioning system (e.g., a satellite network or a terrestrial network fault). While fault-FREE FEARED EVENT may occur when the positioning system inputs an error, this event is not caused by a failure of the positioning system, for example, in a GNSS environment, fault-FREE FEARED EVENT includes regular times of day experience, such as poor satellite geolocation, strong atmospheric gradients and signal discontinuities.

Typically, when an event occurs with PL greater than AL and the duration of the event is greater than TTA, the positioning system declares it unavailable, i.e., the positioning system loses positioning integrity.

As described above, the configuration change trigger condition may include a condition that the positioning integrity does not conform to a positioning integrity index, where, as known from the above description, the positioning integrity index may include AL, TTA, and TIR, and the positioning integrity index may be autonomously specified by the network side device and configured to the UE.

In an alternative embodiment of the present application, if the network side device sends configuration change trigger conditions corresponding to each PRS transmission link respectively, in this case, for any PRS transmission link, if it is determined, based on a measurement result, that positioning integrity obtained by the UE on the PRS transmission link does not conform to a positioning integrity index corresponding to the PRS transmission link, the UE may send a configuration change request to the network side device.

Optionally, the UE may calculate PL corresponding to the PRS transmission link according to a measurement result or according to a measurement result and a TIR value corresponding to the PRS transmission link, and if there is an event that PL is greater than AL corresponding to the PRS transmission link and the duration of the event is greater than TTA corresponding to the PRS transmission link, it may determine that positioning integrity obtained by the UE on the PRS transmission link does not conform to a positioning integrity index corresponding to the PRS transmission link, and in this case, the UE may send a configuration change request to the network side device.

In an alternative embodiment of the present application, if the configuration change trigger condition sent by the network side device is for the final positioning result of the UE, in this case, if it is determined based on the measurement result that the positioning integrity of the final positioning result of the UE does not conform to the positioning integrity index corresponding to the final positioning result of the UE, the UE may send a configuration change request to the network side device.

Optionally, the UE may calculate PL corresponding to the final positioning result of the UE according to the measurement result, or according to TIR corresponding to the measurement result and the final positioning result of the UE, and if there is an event that PL is greater than AL corresponding to the final positioning result of the UE and the duration of the event is greater than TTA corresponding to the final positioning result of the UE, it may determine that the positioning integrity of the final positioning result of the UE does not conform to the positioning integrity index corresponding to the final positioning result of the UE, and in this case, the UE may send a configuration change request to the network side device.

2. A condition occurs that configures a replacement trigger event.

The configuration change triggering event may include at least one of the above-described concerns and events in which the K factor in the rice distribution satisfied by the received signal envelope is less than the target threshold, where the concerns have been described above, and embodiments of the present application are not repeated herein.

In order to facilitate the reader's understanding of the "event that the K factor in the rice distribution satisfied by the envelope of the received signal is less than the target threshold", embodiments of the present application will be briefly described below in view of multipath effects:

Multipath effect (English) refers to the phenomenon that after electromagnetic waves propagate through different paths, the time for each component field to reach a receiving end is different, and the component fields are mutually overlapped according to respective phases to cause interference. The different propagation paths of the electromagnetic wave may include two paths of non-line of sight (english: non line of sight; abbreviated as NLOS) and line of sight (LOS), wherein the non-line of sight (NLOS) refers to indirect point-to-point communication between the receiving end and the transmitting end, the most direct explanation of the non-line of sight is that two points of sight of the communication are blocked, the two points of sight cannot see each other, and the line of sight (LOS) refers to straight line propagation of signals between the transmitting end and the receiving end without shielding.

In the field of communications, a rice distribution may be generally used to reflect the distribution of the envelope of a received signal, where a K factor in the rice distribution may reflect the ratio of the energy content of a component field of an LOS path in the received signal in a signal received by a receiving end, and in general, the higher the value of the K factor, the higher the ratio of the energy content of a component field of the LOS path in the signal received by the receiving end.

Wherein, the mathematical expression of rice distribution is:

In the above mathematical expression, K _d is a K factor, α _i is an attenuation factor (english: attenuationfactor), ω _c is carrier wave x 2 pi, Φ _i is a relative phase of the ith multipath reflected wave and the line-of-sight signal, N is the number of multipath reflected waves, and t is time.

In general, the UE may calculate the K factor from the measurement of PRS.

As described above, the configuration change trigger event may include an event that a K factor in a rice distribution satisfied by the received signal envelope is less than a target threshold, where the target threshold may be autonomously specified and configured to the UE for the network side device.

In an alternative embodiment of the present application, if it is determined that a corresponding configuration change trigger event occurs on any PRS transmission link according to a measurement result of PRS, the UE may send a configuration change request to a network side device.

It should be noted that, optionally, the configuration change request sent by the UE to the network side device may carry at least one of the following identifiers: the identification of the configuration of the current PRS, the identification of the configuration of the access network device that is currently sending PRS to the UE, the identification of the configuration change trigger event that occurred, and the identification of the failure to meet the positioning integrity indicator.

Wherein the identification of the configuration of the current PRS and the identification of the configuration of the access network device currently sending PRS to the UE may be, but is not limited to, the following identifications:

dl-PRS-ID-r16、INTEGER(0..255)、nr-PhysCellID-r16、NR-PhysCellID-r16、nr-CellGlobalID-r16、NCGI-r15。

In an alternative embodiment of the present application, after sending a configuration change request to the network side device, the UE may receive configuration change information sent by the network side device based on the configuration change request, where the configuration change information is used to indicate at least one of a configuration of the PRS after modification and a configuration of the access network device that sends the PRS to the UE after modification.

After receiving the configuration change information, the UE may release at least one of a configuration of an original PRS and a configuration of an access network device that transmits PRS to the UE and receive PRS based on an indication of the configuration change information.

In an alternative embodiment of the present application, the configuration change information may provide assistance data (English: LPP provider ASSISTANCE DATA) signaling for the LPP.

Referring to fig. 6, a flowchart of a configuration changing method according to an embodiment of the present application is shown, where the configuration changing method is applied to the network side device 404 shown in fig. 4, and as shown in fig. 6, the configuration changing method includes the following steps:

In step 601, the network side device sends a configuration change trigger condition to the UE.

The configuration change triggering condition has been described above, and the embodiments of the present application are not described herein again.

Step 602, the network side device receives a configuration change request sent by the UE.

The configuration change request is sent by the UE after a measurement result obtained by measuring the received PRS meets the configuration change trigger condition.

The configuration change request has been described above, and the embodiments of the present application are not described herein again.

Step 603, the network side device changes at least one of the following configurations for the UE based on the configuration change request:

Configuration of PRS;

Configuration of access network equipment transmitting PRS to UE.

Wherein, it should be noted that, in the case that the configuration change trigger condition sent by the network side device is a condition of a final positioning result for the UE, the network side device changes the configuration to include one of the following:

And replacing part of adjacent cell access network equipment which sends PRS to the UE at present with new access network equipment, and adding corresponding PRS configuration for each new access network equipment.

It should also be noted that, in the case where the network side device sends configuration change trigger conditions for each PRS transmission link to the UE, the network side device changes the configuration to include one of:

And replacing the access network equipment in the PRS transmission link, the measurement result of which meets the corresponding configuration change triggering condition, with new access network equipment, and adding corresponding PRS configuration for the new access network equipment.

In an optional embodiment of the application, the network side device changes at least one of the configuration of the PRS for the UE and the configuration of the access network device sending the PRS to the UE based on the configuration change request, including the following: the network side equipment sends configuration replacement information to the UE, wherein the configuration replacement information is used for indicating at least one of the changed configuration of the PRS and the changed configuration of the access network equipment which sends the PRS to the UE.

Referring to fig. 7, a flowchart of a configuration change method according to an embodiment of the present application is shown, where the configuration change method is applied in the implementation environment shown in fig. 4, and as shown in fig. 7, the configuration change method includes the following steps:

step 701, the LMF sends a configuration change trigger condition to the UE.

Step 702, the UE receives a configuration change trigger condition sent by the LMF.

Step 703, the UE measures PRS sent by the access network device hosting the cell and the access network device of the neighboring cell.

Step 704, if the measurement result obtained by measuring the PRS meets the configuration change trigger condition, the UE sends a configuration change request to the LMF.

Step 705, the LMF sends configuration change information to the UE based on the configuration change request.

The configuration change information is used for indicating at least one of the configuration of the changed PRS and the configuration of the access network equipment which sends the PRS to the UE after the change.

Step 706, the UE receives the configuration change information sent by the LMF.

Step 707, the UE releases at least one of the configuration of the original PRS and the configuration of the access network device sending the PRS to the UE and receives the PRS based on an indication of the configuration change information.

Step 708, the UE sends a positioning measurement report to the LMF based on the received PRS.

For example, the positioning measurement report may be the difference between the time stamp of the received PRS and the time stamp of the transmitted SRS.

It should be understood that, although the steps in the flowcharts of fig. 5-7 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows.
