The related technologies related to the embodiments of the present application mainly include GNSS main performance and NR positioning technologies, etc., which are briefly described below.

GNSS main Performance

The necessary navigation performance of the navigation system is considered to be embodied in four aspects by the international civil aviation organization: accuracy, integrity, continuity, and availability.

Accuracy, which is the coincidence of the position provided by the system to the vehicle and the then current true position of the vehicle, is the deviation of the navigational observations and their calculated position results from a true estimate, and is usually expressed in terms of error limits;

integrity refers to the ability of the navigation system to issue timely alarms when any malfunction or error in the system exceeds allowable limits. Integrity refers to the ability to alert the user in time when the system is not available for navigation, and integrity risk is the probability of a dangerous navigation message not being detected.

Continuity refers to the probability that a system will complete its function with a specified performance in a specified time under a given use condition. Continuity refers to the possibility of meeting precision and integrity throughout a predetermined flight phase. The continuity risk is the possibility of an abnormally interrupted navigation being detected after the approach to the start of the flight.

Availability refers to the percentage of time that the system can provide available navigation services for the vehicle. The system can only be called usable after three performances of precision, integrity and continuity are satisfied. The availability of a satellite navigation system is determined by the mobile satellites, a certain coverage area and other factors, and it may take a long time to repeat the failure of the satellites, and it may take many years to determine the availability of the navigation system.

Integrity, as one of the main performances of GNSS, provides guarantees for the availability of positioning technology.

NR positioning technique

Position is one of the indispensable applications in life at present, and the requirements on delay and accuracy of positioning are becoming stricter and stricter. In many positioning applications, precise positioning is typically achieved through a combination of technologies, such as 1) GNSS based provision of location information in outdoor scenarios, 2) radio technologies (e.g. LTE networks, offering a variety of options to locate users, wireless networks, terrestrial beacon systems, etc.), 3) Inertial Measurement Units (IMUs) or sensors (e.g. accelerometer based tracking of user position, gyroscopes, magnetometers or vertical positioning with barometric pressure sensors). These techniques are expected to play an important role in achieving accurate user positioning in the future.

The enhanced positioning capability of the 3GPP NR brings additional gains. The operation of the low and high frequency bands (i.e., FR1 and FR 2) and the use of a large number of antenna arrays provides an additional degree of freedom, greatly improving the positioning accuracy. Based on positioning technologies such as an Observed Time Difference of Arrival (OTDOA), an Uplink Time Difference of Arrival (UTDOA), a Cell-ID or E-Cell-ID, and the like, time measurement using a large bandwidth (low frequency band and high frequency band) brings better performance for user positioning. With large-scale antenna systems (massive MIMO), more accurate user location is achieved by combining time measurements and the spatial and angular domains of the propagation channel.

The Rel-15 NR Positioning topic defines Cell-ID (with Cell port ID) and RAT-independent Positioning method based on long term evolution Positioning Protocol (LPP). Rel-16, mainly studies NR standard RAT-dependent positioning methods, including Downlink Time Difference of Arrival (DL-TDOA), downlink departure angle DL-AoD, uplink Time Difference of Arrival (UL-TDOA), uplink angle of Arrival (UL-AoA), round-Trip Time (RTT), and enhanced cell identification (E-CID).

LPP&NRPPa protocol

The LPP PDU is carried in NAS PDU between the AMF and the UE. LPP is a protocol layer for supporting LPP message transmission between the LMF and the UE. The LPP PDU is carried in a NAS PDU between the AMF and the UE. PDCP is a packet data convergence protocol layer, RLC is a logical link layer, MAC is a media access control layer, L1 is a physical layer, IP is an internet protocol layer, SCTP is a stream control transmission protocol layer, NGAP is an NG interface application protocol layer, TCP is a transmission control protocol layer, TLS is a security transmission protocol layer, HTTP is a hypertext transfer protocol layer, NG RAN is a 5G radio access network, AMF is an authentication management domain entity, and specific descriptions are given to the protocol stack layers in the relevant standards, which are not described herein again.

NRPPa is the protocol layer used to support transfer of NRPPa PDUs between LMF and NG-RAN Node as shown in FIG. 1C for the NRPPa protocol stack. NRPPa is a protocol layer used to support the transmission of NRPPa PDUs between LMF and NG-RAN nodes. The protocol stack layers are explicitly described in the relevant standards, and are not described herein again.

Currently, integrity assurance is mainly implemented in a positioning technology of GNSS, and for RAT-dependent positioning technology, 3GPP is currently also used for research on assurance of positioning integrity.

In view of the foregoing problems, an integrity configuration method is provided in an embodiment of the present application, which mainly includes the following stages:

A. the LMF issues an integrity configuration and/or a measurement configuration/measurement result, the integrity configuration indicating a policy for determining integrity information, the measurement configuration indicating a measurement configuration for a plurality of monitored devices, the monitored devices including satellites or TRP/gNB.

B. The first UE, or the LMF, or the TRP/gNB, or the third-party device performs measurement of positioning reference signals of the multiple monitored devices to obtain a measurement result of the first UE, the LMF, or the first UE, or the TRP/gNB determines location information of the first UE according to the measurement result, and the third-party device may be a network device with a known fixed location other than the LMF and the TRP/gNB, such as other gnbs, integrity monitoring devices, reference stations, and the like.

C. And the first UE or the LMF or the TRP/gNB or the third-party equipment determines integrity information according to the measurement result, and the first UE determines first integrity information of the position information.

The following four implementation modes are provided for C splitting

First, the LMF determines integrity information from the measurements.

Second, the first UE determines integrity information according to the measurement result.

Thirdly, the TRP/gNB determines integrity information from the measurement results.

Fourth, the third party device determines integrity information based on the measurement.

The following detailed description is made with reference to the accompanying drawings.

Referring to fig. 2A, fig. 2A is a schematic flowchart illustrating an integrity configuration method according to an embodiment of the present application, where the method includes:

step 201, the first device sends a first message to the second device and/or the third device, where the first message is used to determine integrity information of the location information.

The integrity information may also be referred to as integrity, availability, etc., and may correspond to english description integrity in the Radio Technical Commission for Maritime services (RTCM) standard protocol

Specifically, the RTCM protocol includes three types of devices, which are a Control Station (CS), a Reference Station (RS), and an Integrity Monitor (IM).

Wherein the Control Station (CS) will receive reports of system anomalies, isolate the fault point, and initiate corrective action as needed. It manages services by setting or resetting device parameters including data recording interval, operating mode, alarm thresholds and intervals, radio Beacon (RBN) almanac information and RTCM message broadcast schedules. Advanced CS implementations provide not only the functionality to collect and store data, but also the functionality to process and display data.

Wherein a Reference Station (RS) generates an RTCM message for broadcasting using a reference receiver and an MSK modulator. The MSK modulator is considered an intrinsic part of the RS. The transmission of the code and carrier phase data to the recorder and/or dedicated lines is optional depending on the requirements of the service provider. Service providers may consider providing RTCM messages for Radio Frequency (RF) modulation or data recording through an additional RS data port, but this function may affect data delay. The RS may or may not be located locally at the broadcast transmitter site. However, the use of remote RSs incurs additional communication link costs and failure mechanisms. Juxtaposing the RS and the Integrity Monitor (IM) at the broadcast site keeps the service fully operational (i.e., operating well, monitored and able to archive data completely) even in the event of a wide area communication link disconnection. Suggesting that RS and IM are co-located; however, the present standard does not preclude the use of remote integrity monitoring and is ready for use with remote monitors. The reference station and integrity monitor message #23 (REFERENCE STATIONS ANDINTEGRITY MONITORS, RISM) #23 provides one potential technique for providing data to a Wide Area DGPS (WADGPS) system.

Wherein, the Integrity Monitor (IM) is used for receiving the RS broadcast and verifying whether the information is in the allowable range. The IM periodically provides positive system feedback to the RS to indicate normal monitored operation. In the event of out of tolerance, the IM may generate an alert. The most important alarms are position and pseudorange correction (PRC) alarms. These require a simple radial error check of the DGPS navigation solution for known positions and analysis of the accuracy of the various ranges from the satellites to the known fixed positions of the IM.

In this possible example, the first message is carried by any one of: LPP PDU, NRPPa PDU, RRC PDU.

In this possible example, the first message is sent by proprietary signaling or by means of broadcast.

In this possible example, the first message is a stand-alone message; alternatively, the first and second electrodes may be,

carried together with other LPP messages/NRPPa messages.

In this possible example, the integrity information includes at least one of: whether user location information is available, whether measurements (pseudoranges) are available, whether current measurements have exceeded an alarm threshold, health of at least one monitored device, alarm information.

The health condition refers to the following parameters transmitted by the integrity monitor function device in the RTCM standard protocol. Device Forced Health (Forced Health), device Forced Unhealthy (Forced Unhealthy), GPS Navigation Message Ephemeris Health Status (GPS Navigation Message Ephemeris Health Status). Pseudorange, pseudo range, refers to the approximate distance between the terrestrial receiver and the satellite during the satellite positioning process. For example, a Global Positioning System (GPS) receiver, which, in order to determine its position, will determine the distances of (at least) four satellites and their positions at the time of transmission. Knowing the orbital parameters of the satellites, these positions can be calculated at any point in time. The pseudo-polar difference for each satellite is obtained by multiplying the time that the signal is received from the satellite to the receiver by the speed of light. Since there is an error in the accuracy of the measurement time, the term pseudo-range is used instead of the range of this distance.

In this possible example, the first device is an LMF entity. Is a positioning central control management center for providing positioning configuration information, calculating position information based on measurement results, and the like. May be identical to the control station CS in the RTCM protocol.

In this possible example, the second device may be equivalent to a reference station RS in the RTCM protocol, for serving as a reference receiver/transmitter to provide observations for the positioning device, or to determine and transmit the integrity information to other devices. The second device is TRP/gNB or UE or third-party equipment.

In this possible example, the third device is configured to receive the integrity information of the first device or the second device and to determine availability of the integrity information; or the integrity information is determined and fed back to other equipment. The third device is a TRP/gNB or a UE or a third party device, and may be equivalent to an integrity monitor IM in the RTCM protocol.

In this possible example, the first message is for at least one of:

a) Configuring/modifying parameters of the second device and/or the third device, the parameters comprising at least one of: alarm threshold, feedback time period, broadcast period;

b) Indicating the health of the monitored equipment/positioning reference signal;

c) Requesting the second device and/or the third device to transmit the indicated health status of the at least one monitored device/positioning reference signal;

d) Requesting the second device and/or the third device to report at least one of: broadcast period, traffic status, differential status, correction data;

e) Requesting the second device and/or the third device to report the position information, the device identification and the health condition of the monitored device/positioning reference signal of the monitored device;

f) Feeding back request information sent by the second equipment and/or the third equipment;

g) Requesting the second device and/or the third device to resend the sent message;

h) Scheduling the second device and/or the third device for data transmission/broadcast, the data comprising at least one of: data to be transmitted, transmission/broadcast cycle configuration.
