The associated technologies involved in the embodiments of this application mainly include GNSS main performance and NR positioning technology, etc., which are briefly introduced below.

GNSS main performance

The International Civil Aviation Organization believes that the necessary navigation performance of the navigation system is reflected in four aspects: accuracy, integrity, continuity and availability.

·Accuracy refers to the degree of coincidence between the position provided by the system for the carrier and the actual position of the carrier at the time, that is, the deviation of the navigation observation and its solution position from the real estimate, it is usually expressed by the error limit;

·Integrity refers to the ability of the system to issue an alarm in time when any failure occurs in the navigation system or the error exceeds the allowable limit. Integrity refers to the ability to promptly warn users when the system cannot be used for navigation. Integrity risk is the probability of undetected dangerous navigation information.

·Continuity refers to the probability that the system completes its function with the specified performance within the specified time under the given conditions of use. Continuity refers to the possibility of meeting accuracy and integrity during the entire scheduled flight phase. Continuity risk is the possibility that an abnormally interrupted navigation is detected after the start of the flight approach.

·Availability refers to the percentage of time that the system can provide usable navigation services for the carrier. The system can be called usable only after satisfying the three performances of accuracy, integrity and continuity. The availability of a satellite navigation system is determined by factors such as moving satellites and a certain coverage area. It may take a long time to repeat satellite failures, and it will take many years to determine the availability of the navigation system.

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

NR positioning technology

Location is one of the indispensable applications in life at present, and the requirements for delay and accuracy of positioning are becoming more and more stringent. In many positioning applications, precise positioning is usually achieved through a combination of multiple technologies, such as 1) providing location information in outdoor scenes based on GNSS, 2) radio technology (such as LTE networks, providing multiple options to locate users, Wireless networks, ground beacon systems, etc.), 3) Inertial Measurement Units (IMU) or sensors (such as accelerometers to track user positions, gyroscopes, magnetometers, or atmospheric pressure sensors for vertical positioning). These technologies are expected to play an important role in realizing accurate user positioning in the future.

The enhanced positioning capabilities of 3GPP NR bring additional gains. The operation of low and high frequency bands (i.e. FR1 and FR2) and the use of a large number of antenna arrays provide additional degrees of freedom and greatly improve positioning accuracy. Positioning technology based on the time difference of arrival (Observed Time Difference of Arrival, OTDOA) and Uplink Time Difference of Arrival (UTDOA), cell identity identification Cell-ID or E-Cell-ID and other positioning technologies, using large bandwidth (low frequency bands) And high frequency band) time measurement brings better performance for user positioning. Using massive antenna systems (massive MIMO), a more accurate user location can be achieved by combining time measurement and the spatial and angular domains of the propagation channel.

The Rel-15 NR positioning subject defines Cell-ID (with cell portion ID) and a RAT-independent positioning method based on the Long Term Evolution Positioning Protocol (LTE Positioning Protocol, LPP). The 16th version of Rel-16 mainly studies NR standalone RAT-dependent positioning methods, including Downlink Time Difference of Arrival (DL-TDOA), Downlink Departure Angle DL-AoD, and Uplink Time Difference of Arrival UL-TDOA, Uplink angle of arrival UL-AoA, round-trip time (Round-Trip Time, RTT), enhanced cell identification E-CID, etc.

LPP&NRPPa agreement

As shown in Figure 1B, the LPP protocol stack, LPP is the protocol layering used to support transfer of LPP messages between an LMF and UE. The LPP PDU is carried in NAS PDU between the AMF and the UE. LPP is a protocol layer used to support LPP message transmission between LMF and UE. The LPP PDU is carried in the NAS PDU between the AMF and the UE. PDCP is the packet data convergence protocol layer, RLC is the logical link layer, MAC is the media access control layer, L1 is the physical layer, IP is the Internet protocol layer, SCTP is the stream control transmission protocol layer, and NGAP is the NG interface application protocol layer. TCP is the transmission control protocol layer, TLS is the secure transmission protocol layer, HTTP is the hypertext transmission protocol layer, NG RAN is the 5G radio access network, AMF is the authentication management domain entity, and the relevant standards have all layers of the protocol stack Make it clear that I won’t repeat it here.

As shown in Figure 1C, NRPPa protocol stack, NRPPa is the protocol layering used to support transfer of NRPPa PDUs between an LMF and NG-RAN Node. NRPPa is a protocol layer used to support NRPPa PDU transmission between LMF and NG-RAN nodes. Each layer of the protocol stack is clearly stated in the relevant standards, so I won't repeat them here.

At present, integrity assurance is currently mainly implemented in GNSS positioning technology. For RAT-dependent positioning technology, 3GPP is currently also used to ensure the integrity of positioning research.

In response to the foregoing problems, an embodiment of the present application proposes a integrity configuration method, which mainly includes the following stages:

A. The LMF issues integrity configuration and/or measurement configuration/measurement results. The integrity configuration indicates the strategy for determining integrity information. The measurement configuration indicates the measurement configuration of multiple monitored devices. The monitored devices include satellites or TRP/gNB .

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

C. The first UE or the LMF or TRP/gNB or the third-party device determines the integrity information according to the measurement result, and the first UE determines the first integrity information of the location information.

Among them, for C split the following four implementation methods

The first is that the LMF determines the integrity information based on the measurement results.

In the second type, the first UE determines the integrity information according to the measurement result.

In the third type, TRP/gNB determines the integrity information based on the measurement results.

Fourth, the third-party equipment determines the integrity information based on the measurement results.

A detailed description will be given below in conjunction with the drawings.

Please refer to FIG. 2A. FIG. 2A is a schematic flowchart of a integrity configuration method provided by an embodiment of the present application. As shown in the figure, 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 the integrity information of the location information.

Among them, the integrity information can also be called integrity, completeness, availability, etc., which can correspond to the English description of integrity in the standard protocol of the Radio Technical Commission for Maritime Services (RTCM)

Specifically, in the RTCM protocol, there are three types of equipment, which are Control Station (CS), Reference Station (RS), and Integrity Monitor (IM).

Among them, the control station (CS) will receive reports of system abnormalities, isolate the point of failure, and initiate corrective actions as needed. It manages services by setting or resetting device parameters, including data logging interval, operating mode, alarm threshold and interval, radio beacon (RBN) almanac information, and RTCM message broadcast schedule. The advanced CS implementation not only provides the function of collecting and storing data, but also the function of processing and displaying data.

Among them, the reference station (RS) uses a reference receiver and an MSK modulator to generate RTCM messages for broadcasting. The MSK modulator is considered an inherent part of RS. Sending the code and carrier phase data to the recorder and/or dedicated line is optional, depending on the requirements of the service provider. Service providers may consider providing RTCM messages through additional RS data ports for radio frequency (RF) modulation or data recording, but this function may affect data delay. The RS can be located at the local broadcast transmitter site or not locally. However, the use of remote RS will bring additional communication link costs and failure mechanisms. Even when the wide-area communication link is disconnected, collocation of RS and Integrity Monitor (IM) at the broadcast site can keep the service fully operational (that is, it is in good condition, monitored and able to fully archive data ). It is recommended that RS and IM be placed in the same location; however, this standard does not exclude the use of remote integrity monitoring, and preparations are made for the use of remote monitoring. Reference station and integrity monitor message #23 (REFERENCE STATIONS AND INTEGRITY MONITORS, RISM) #23 provides a potential technology to provide data to a wide area DGPS (WADGPS) system.

Among them, the integrity monitor (Integrity Monitor, IM) is used to receive the RS broadcast and verify whether the information is within the allowable range. IM regularly provides positive system feedback to RS to indicate normal monitored operation. In the case of out of tolerance, IM will generate an alert. The most important alarms are the position and pseudorange correction (PRC) alarms. These requirements perform a simple radial error check on the DGPS navigation solution against the known position, and analyze the accuracy of each range from the satellite to the known fixed position of the IM.

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

In this possible example, the first message is sent through dedicated signaling or sent through broadcast.

In this possible example, the first message is an independent message; or,

Carried together with other LPP messages/NRPPa messages.

In this possible example, the integrity information includes at least one of the following: whether user location information is available, whether the measurement result (pseudorange) is available, the current measurement value has exceeded the alarm threshold, the health status of at least one monitored device, Alarm information.

Among them, the health status refers to the following parameters sent by the device with the integrity monitor function in the RTCM standard protocol. The equipment is forced to be healthy (Forced Healthy), the equipment is forced to be unhealthy (Forced Unhealthy), GPS navigation message ephemeris Health Status (GPS Navigation Message Ephemeris Health Status). Pseudorange is the approximate distance between the ground receiver and the satellite during satellite positioning. For example, in a global positioning system (GPS) receiver, in order to determine its location, the satellite navigation receiver will determine the distance of (at least) four satellites and their location at the time of transmission. Knowing the satellite's orbital parameters, these positions can be calculated at any point in time. The pseudo-range of each satellite is obtained by multiplying the time from the satellite to the receiver by the speed of light. Due to the accuracy error in 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. It is the positioning control management center, used to provide positioning configuration information, calculate location information based on measurement results, etc. It can be equivalent to the control station CS in the RTCM protocol.

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

In this possible example, the third device is used to receive the integrity information of the first device or the second device, and to determine the availability of the integrity information; or, to determine the Integrity information and feedback to other equipment. The third device is TRP/gNB or UE or a third-party device, which may be equivalent to the integrity monitor IM in the RTCM protocol.

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

a) Configure/modify the parameters of the second device and/or the third device, where the parameters include at least one of the following: an alarm threshold, a feedback time period, and a broadcast period;

b) Indicate the health status of the monitored equipment/location reference signal;

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

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

e) Request the second device and/or the third device to report the location information, device identification, and health status of the monitored device/location reference signal of the monitored device;

f) Feed back the request information sent by the second device and/or the third device;

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

h) Scheduling the second device and/or the third device to perform data transmission/broadcasting, where the data includes at least one of the following: data to be transmitted, and transmission/broadcast period configuration.
