Background

In the related art, in a Non-terrestrial network (NTN, non-Terrestrial Networks), a terrestrial integration, a universal sensing integration, or other industrial scenarios, it is often required that a terminal (UE) reports its own location information, for example, location information based on an application layer such as a global navigation satellite system (GNSS, estimation-Global Navigation Satellite System), bluetooth (Bluetooth), etc., where in reality, the location information reported by the terminal may be inaccurate or have a certain false possibility, and it is required to further verify the location of the terminal based on the communication network. When the network side verifies the position of the terminal, if the network needs to confirm the position information reported by each UE at each time, a network connection positioning process is triggered, the signaling overhead is too large, and the power is consumed; in addition, the existing positioning flow relies on a high-precision technology of a Non-Access-Stratum (NAS), and all flows need to be comprehensively confirmed through multiple rounds of interaction with a positioning management function (LMF, location Management Function). For the NTN scenario, a lot of time is consumed for transmission of multiple rounds of NAS signaling.

Detailed Description

In the related art, the network side cannot directly obtain the location information of the terminal, and needs to further verify the location of the terminal based on the wireless network. For example, in the case that the network side acquires the GNSS location information reported by the terminal, it is considered that the GNSS location information may be inaccurate or have a certain false possibility, and the network side needs to further verify the GNSS location information reported by the terminal based on the wireless network.

Since the location information of the UE is applied to NTN-related uplink time-frequency compensation, conditional handover, mobility management entity (MME, mobility Management Entity) selection, mapping to a cell of a terrestrial network, etc., each time the network side verifies the location of the terminal, a network-to-network positioning process is triggered to complete one network-to-network positioning, and the network side needs to send multiple rounds of NAS signaling to the LMF. Therefore, in the NTN scenario, if the network side confirms the position information reported by each terminal each time, the signaling overhead is too large, and a lot of time is required for transmitting multiple rounds of NAS signaling.

Based on the above, in each embodiment of the present application, a first network device sends a first signaling to a terminal, where the first signaling is used to indicate information reported by the terminal; the terminal receives a first signaling sent by the first network equipment and reports information reported by the first signaling indication to the first network equipment; and the first network equipment receives the information reported by the terminal, so that the first network equipment performs position verification on the terminal based on the information reported by the terminal. The network side can reduce the interaction times between the network side and the terminal in the process of verifying the position of the terminal, thereby reducing the signaling overhead and shortening the total time consumption for transmitting related signaling.

The present application is described in further detail below with reference to the accompanying drawings and examples.

The embodiment of the application provides a location verification method, which is applied to a first network device, wherein the first network device can be any network device capable of performing location verification, the first network device comprises a base station, and referring to fig. 1, the method comprises:

step 101: and sending the first signaling to the terminal.

Step 102: and receiving information reported by the terminal based on the first signaling.

information of at least one NTN sub-cell;

beam information and CGI under PCI of at least one cell of the ground network;

Here, the first information characterizes information of the first reference signal received by the terminal at the position where the reported position information is located.

The measurement information corresponding to the PCI of the at least one ground network comprises at least one of the following:

RSRP；

RSRQ；

SINR；

a reception time;

reference signal time difference (RSTD, reference Signal Time Difference);

receiving a transmission time difference, and representing a time difference between the receiving time and the transmission time;

and receiving and transmitting time delay difference, and representing the time difference between the receiving time delay and the transmitting time delay.

The first signaling indicates that the information reported by the terminal corresponds to the position information reported by the terminal. The information reported by the first signaling indication terminal is used for the network side to verify whether the position information reported by the terminal is credible or not.

It should be noted that, the TA in the NTN is bound to the location information of the TA, and in the terrestrial network, one TA includes a plurality of cells, but the coverage area of the cell of the NTN is ten times or more than that of the cell of the terrestrial network, and sometimes, one NTN cell may include a plurality of TAs; the NTN cells include NTN serving cells and/or NTN neighbor cells.

Under the condition that first TA information and/or second TA information reported by a terminal are received, the first network equipment determines position information corresponding to the corresponding TA based on the first TA information and/or the second TA information; the first network device may compare the location information corresponding to the TA information reported by the terminal with the location information reported by the terminal, and verify whether the location information reported by the terminal is trusted based on the corresponding comparison result. And under the condition that the position information reported by the terminal is consistent with the position information corresponding to the corresponding TA, the position information reported by the terminal is credible. Under the condition that the terminal reports the first TA information and the second TA information, the comparison result corresponding to the first TA information and the comparison result corresponding to the second TA information both represent that the position information reported by the terminal is credible when the position information reported by the terminal is consistent with the position information corresponding to the corresponding TA, so that the accuracy of verifying the position information reported by the terminal at the network side can be improved.

It should be noted that, the first network device may divide each NTN cell into at least one NTN sub-cell correspondingly; the NTN subcell may be understood as a virtual cell. Under the condition that the first network equipment receives the information of at least one NTN sub-cell reported by the terminal, inquiring the position information corresponding to the NTN sub-cell reported by the terminal from a database, comparing the position information corresponding to the corresponding NTN sub-cell with the position information reported by the terminal, and verifying whether the position information reported by the terminal is credible or not based on a corresponding comparison result.

The first network device may further instruct the terminal to report CSI-RS, and under the condition that the first network device receives the CSI-RS reported by the terminal, map each CSI-RS to one NTN sub-cell, so as to determine location information of the terminal based on location information corresponding to TA included in the NTN sub-cell, and perform location verification on the location information reported by the terminal based on the determined location information.

The first network device may also send different first reference signals in different NTN sub-cells, so that the terminal performs positioning measurement and reporting of the result on the first reference signals. Therefore, under the condition that the information reported by the terminal contains the first information, the first network equipment can determine all first reference signals received by the terminal at the position reported by the terminal based on the received first information, so that the NTN sub-cell corresponding to the terminal is determined based on the determined first reference signals, and further, the position verification is carried out on the position information reported by the terminal based on the position information corresponding to the NTN sub-cell. And when the position information reported by the terminal is consistent with the position information corresponding to the NTN sub-cell, the position information reported by the terminal.

Wherein the first reference signal is CSI-RS, SSB, PRS or TRS. The information of the first reference signal comprises an identification of the first reference signal and/or measurement information of the first reference signal. The measurement information of the first reference signal includes: at least one of a measured value, RSTD, a received transmit time difference, and a received transmit time delay difference. The measured value includes at least one of RSRP, RSRQ, and SINR.

Optionally, in an embodiment, in a case that the information reported by the first signaling indication terminal includes information of a cell of at least one ground network, the information reported by the first signaling indication terminal further includes:

and the information of partial system information of the district of the ground network corresponding to the position information reported by the terminal.

The first network equipment maps the position information reported by the terminal to a ground base station and/or a ground network cell, and instructs the terminal to read the information of the ground network cell and/or the beam information under the ground network cell and/or part of system message information mapped by the position information reported by the terminal.

Because the coverage area of the NTN is ten times more than that of the ground cell, the first network equipment maps the position information reported by the terminal to the ground base station and/or the cell of the ground network, and instructs the terminal to read and report the information of at least one ground base station and/or the cell of the ground network, which are covered and/or crossed with the position of the terminal. For example, the terminal is instructed to report the PCIs of the cells of 1-3 terrestrial networks, or further report the beam information and CGI under the PCIs of the cells of the terrestrial networks.

And under the condition that the first network equipment receives the information of the cell of at least one ground network reported by the terminal, judging whether the position information corresponding to the information of the cell of the ground network reported by the terminal is consistent with the position information reported by the terminal, thereby judging whether the position information reported by the terminal is credible.

Or the first network device directly judges whether the position information which is reported by the terminal and corresponds to the cell of the ground network and can be found, monitored and/or measured is consistent with the position information reported by the terminal, so that whether the position information reported by the terminal is reliable is judged.

For example, when the first network device receives the PCI of at least one ground network, the first network device searches the position information corresponding to the PCI in the database, and verifies whether the position information reported by the terminal is trusted based on the position information corresponding to the PCI. And under the condition that the position information reported by the terminal is consistent with the position information corresponding to the PCI, the position information reported by the terminal is credible.

Under the condition that the first network equipment receives the beam information and the CGI under the PCI of at least one ground network, the first network equipment searches the beam information and the CGI under the PCI reported by the terminal in a database; under the condition that the beam information and the CGI under the PCI reported by the terminal are found, based on the found beam information and CGI under the PCI and based on the beam information and the CGI under the PCI reported by the terminal, whether the position information reported by the terminal is credible or not is verified. And aiming at the same PCI, if the searched beam information is the same as the beam information reported by the terminal and the searched CGI is the same as the CGI reported by the terminal, the position information reported by the terminal is credible.

And under the condition that the first network equipment receives the measurement information corresponding to the PCI of at least one ground network, determining the position information of the terminal based on the measurement information corresponding to the PCI reported by the terminal, and verifying whether the position information reported by the terminal is credible or not based on the determined position information. And under the condition that the position information reported by the terminal is the same as the position information determined correspondingly, the position information reported by the terminal.

Under the condition that the position information reported by the terminal is received, the first network equipment maps the position information reported by the terminal to a ground base station and/or a ground network cell, and instructs the terminal to read the information of the mapped ground network cell and/or the beam under the ground network cell, and/or instructs the terminal to acquire the measurement information of the mapped ground network cell and/or the beam under the ground network cell.

Under the condition that the first network equipment receives measurement information corresponding to the PCI of at least one cell of the ground network reported by the terminal, the first network equipment determines the position information of the terminal according to the measurement value of the reference signal reported by the terminal, and judges whether the position information determined by the terminal is consistent with the position information reported by the terminal, thereby judging whether the position information reported by the terminal is credible.

Optionally, in an embodiment, when the information reported by the first signaling instruction terminal includes measurement information corresponding to a PCI of at least one cell of the ground network, the information reported by the first signaling instruction terminal further includes:

and the terminal reports the information of the district of the ground network corresponding to the position information.

The first network equipment maps the position information reported by the terminal to a ground base station and/or a ground network cell and instructs the terminal to read the information of the ground network cell and/or the beam under the ground network cell mapped by the position information reported by the terminal; and/or instruct the terminal to acquire the measurement information of the ground network cell and/or the beam under the ground network cell mapped by the position information reported by the terminal.

Here, since the coverage area of the NTN is ten times or more than that of the terrestrial cell, the first network device maps to the terrestrial base station and/or the terrestrial network cell according to the location information reported by the terminal, and instructs the terminal to measure the reference signal of at least one terrestrial base station and/or the terrestrial network cell that is covered and/or intersected with the location of the terminal, for example, instructs the terminal to read the PCIs of 1-3 terrestrial base stations and/or the terrestrial network cells, or further instructs the terminal to measure the reference signal of the beam information under the PCIs of the terrestrial base stations and/or the terrestrial network cells. The first network equipment determines the position information of the terminal according to the measured value of the reference signal reported by the terminal, and judges whether the position information determined by the terminal is consistent with the position information reported by the terminal, thereby judging whether the position information reported by the terminal is credible.

The implementation process of the first network device for performing the location verification on the terminal will be described in detail below by taking the location information reported by the terminal and the measured value of the first reference signal as an example.

The implementation process of the first network device for carrying out position verification on the terminal by adopting a first position verification mode is as follows:

and the terminal reports the position information to each of the at least two network devices and sends a second reference signal. In practical applications, the location information may be location coordinates, and the second reference signal may be a sounding reference signal (SRS, sounding Reference Signal).

And under the condition that the position information reported by the terminal is the same as the determined position information, the first position verification result represents that the position information reported by the terminal is credible.

In an embodiment, the location information reported by the terminal includes the current location information of the terminal and the location information of each time at least one time predicted by the terminal.

Here, the first network device may perform location verification on the current location information of the terminal, and verify the reliability of the location information predicted by the terminal based on the location verification result of the current location information.

The location information of each time instant at least at one time instant in the future predicted by the terminal may be represented by any one of the following:

A time stamp and corresponding location information;

a first function; the first function may be a first order function, a second order function, or a multiple order function.

The implementation process of the first network device for carrying out position verification on the terminal by adopting the second position verification mode is as follows:

for example, a first network device transmits a first reference signal; each of the at least two terminals receives and measures a first reference signal to obtain a measured value of the first reference signal, and reports first position information of the terminal and the measured value of the first reference signal. Wherein, at least two terminals are all located in the position area that sets for. The measured value of the first reference signal may be at least one of RSRP, RSRQ, and SINR.

The first network equipment receives the position information reported by each terminal and the measured value of a first reference signal; and determining the terminals with similar positions or the first part of the position information positioned in the set position range from at least two terminals based on the position information reported by each terminal.

The first network device may perform location verification according to any one of the following schemes when determining the first portion of terminals:

scheme one: location verification based on minority compliance majority principle

The first network device determines the number of each measurement value based on the measurement value of the first reference signal by each terminal in the first part of terminals according to a rule of minority compliance and majority compliance. The first network device determines trusted and untrusted terminals in the first portion of terminals based on the measured value of the first reference signal and the number of each measured value by each terminal in the first portion of terminals. The measurement values of the trusted terminals in the first part of terminals to the first reference signal are the same or similar, and the number of the measurement values of the trusted terminals in the first part of terminals to the first reference signal is larger than that of the untrusted terminals to the first reference signal.

The second part of terminals are position verified based on the measurement of the first reference signal by the trusted terminal in the first part of terminals and based on the measurement of the first reference signal by each terminal in the second part of terminals. Wherein if the measured value of the first reference signal by any terminal in the second part of terminals is the same as or similar to the measured value of the first reference signal by the trusted terminal in the first part of terminals, the terminal in the second part of terminals is the trusted terminal.

Scheme II: location verification based on minority compliance majority principle

For example, the first network device determines the number of each measurement value based on the measurement value of the first reference signal by some or all terminals in the first part of terminals; and determining a first measured value meeting the set condition based on the number of each measured value, and determining the terminal corresponding to the first measured value as a trusted terminal in the first part of terminals. The setting condition may be that the number of the first measurement values is the largest, or that the percentage between the number of the first measurement values and the total number of the selected measurement values is larger than the setting percentage. The set percentage may be 90%.

The first network device performs a location verification for the second part of terminals based on the measurements of the first reference signal by the trusted terminals in the first part of terminals and based on the measurements of the first reference signal by each of the second part of terminals. For example, the first network device determines a first difference between the measured value of the first reference signal and the first measured value for each of the second portion of terminals; and under the condition that the first difference value corresponding to any one of the terminals in the second part is smaller than or equal to a set threshold, the terminal in the second part is a trusted terminal. And under the condition that the first difference value corresponding to any one of the terminals in the second part is larger than the set threshold, the terminal in the second part is an untrusted terminal.

Scheme III: position verification based on credit terminal principle

The first network equipment adopts a first position verification mode to respectively verify the position information reported by each terminal in the first part of terminals to obtain a first position verification result of each terminal in the first part of terminals, and the first position verification result represents whether the position information reported by the corresponding terminal is credible or not; determining a trusted terminal in the first part of terminals based on a first position verification result of each terminal in the first part of terminals; and performing position verification on a second part of terminals based on the measurement value of the first reference signal by the trusted terminal and the measurement value of the first reference signal by the second part of terminals in the plurality of terminals. The first network device may determine the second difference based on a measurement value of the first reference signal by the terminal in the second portion of terminals and a measurement value of the first reference signal by the trusted terminal; and under the condition that the absolute value of the second difference value is smaller than the set threshold, the position information reported by the corresponding terminal in the second part of terminals is reliable.

In the third scheme, a first position verification mode is adopted to determine a trusted terminal in a first part of terminals, and position information reported by the trusted terminal in the first part of terminals is trusted; and carrying out position verification on the second part of terminals based on the measured value of the first reference signal by the trusted terminal in the first part of terminals, thereby improving the credibility of the position verification result.

In order to reduce signaling overhead of location verification and improve location verification efficiency, in a case that the network side performs location verification on the terminal based on the second location verification mode, the method further includes:

The first network device determines a trusted terminal among a first set percentage of the first part of terminals, if the first part of terminals is determined among the at least two terminals. The first percentage may be less than 100%, or may be 100%. The trusted terminal may be determined based on a minority compliance majority principle or a trusted terminal principle.

The first network equipment selects a second set percentage of trusted terminals from the determined trusted terminals; determining a first verification value corresponding to a first part of terminals based on a measured value of the second set percentage of trusted terminals to the first reference signal; comparing the measured value of the first reference signal by each terminal in the second part of terminals with the first verification value to obtain a comparison result; and verifying whether the position information reported by the corresponding terminal in the second part of terminals is credible or not based on the comparison result corresponding to each terminal in the second part of terminals.

The first verification value may be a mean value, a maximum value or a minimum value of the measured value of the first reference signal by the trusted terminal with the second set percentage. The trusted terminals of the set percentage in the first part of terminals refer to the trusted terminals of the second set percentage in the first part of terminals. In practice, the second set percentage may be 90%.

Under the condition that the comparison result corresponding to any one of the terminals in the second part of terminals meets any one of the following, the position information reported by the terminal is credible:

the measured value of the terminal to the first reference signal is the same as the first verification value;

the absolute value of the difference between the measured value of the first reference signal and the first verification value is smaller than a set threshold value.

In order to improve the reliability of the location verification result, in an embodiment, before determining the first verification value corresponding to the first part of terminals, the method further includes:

feeding back the corresponding first score to the terminal and/or sending the corresponding first score to the second network equipment;

Here, the first network device establishes a credit record for each terminal, where the credit record is used to record a first score of the corresponding terminal, so that the network side can determine, based on the first score corresponding to the terminal, whether the location information reported by the corresponding terminal is trusted or not, and whether location verification is required for the terminal.
