A method for checking position information and an apparatus thereof provided by the present disclosure are described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a method for verifying location information according to an embodiment of the disclosure, where the method is performed by an access network device. As shown in fig. 2, the method may include, but is not limited to, the steps of:

Step 201, receiving position information reported by a terminal device.

Wherein the location information is any one of the following: based on the position information acquired by the global navigation satellite system GNSS, the identification of the cell in which the terminal equipment is located.

In the present disclosure, in a GNSS system, after a terminal device obtains location information of the terminal device based on GNSS, the terminal device may report the GNSS location information to an access network device.

Or, the terminal device may also determine the cell in which the terminal device is currently located according to the identifier of the accessed network device, such as the identifier of the service base station, the identifier of the service satellite or the identifier of the service beam, and send the identifier of the cell in which the terminal device is located to the access network device. Then, the access network device can determine the current position information of the cell corresponding to the identifier of the cell where the terminal device is located, and can determine the position information of the cell where the terminal device is located as the position information of the cell where the terminal device is located.

Step 202, receiving reference position information of terminal equipment sent by core network equipment.

Wherein the reference position information is any one of the following: based on the position information of the terminal equipment determined by the communication system, the identity of the cell in which the terminal equipment is located.

In the present disclosure, the location information of the terminal device determined based on the communication system may be location information of the terminal device determined using a conventional location method, for example, a radio access technology (radio access technology dependent, RAT-dependent) based location method. After acquiring the position information of the terminal equipment determined based on the communication system, the core network equipment can send the position information of the terminal equipment to the access network equipment as the reference position information of the terminal equipment.

Or the core network device may first determine the cell in which the terminal device is located, and send the identifier of the cell in which the terminal device is located to the access network device, and then, the access network device may determine, according to the identifier of the cell in which the terminal device is located, the location of the cell in which the terminal device is located, and may determine the location information of the cell in which the terminal device is located as the reference location information of the terminal device.

Optionally, the reference location information may include an identifier of the terminal device, and thus, the access network device may determine, according to the identifier of the terminal device, the terminal device associated with the reference location information. The identity of the terminal device may be any information that can uniquely determine the terminal device, such as an identity (identity document, ID) of the terminal device, which is not limited in this disclosure.

And 203, checking the reported position information based on the reference position information.

It can be understood that the location information reported by the terminal device should be consistent with the reference location information determined by the core network device, and if the location information is inconsistent or widely different, the location information reported by the terminal device is unreliable.

In the present disclosure, the reference location information may be compared with the location information reported by the terminal device, so as to verify whether the reported location information is reliable.

For example, the position information acquired based on GNSS may be compared with the position information of the terminal device determined based on the communication system, the GNSS position information may be determined to be reliable when the position information acquired based on GNSS is consistent with the position information of the terminal device determined based on the communication system, and the GNSS position information may be determined to be unreliable when the position information acquired based on GNSS is inconsistent with the position information of the terminal device determined based on the communication system.

For another example, the identifier of the cell in which the terminal device is located and the identifier of the cell in which the terminal device is located in the reference location information may be compared, when the identifiers of the cells in which the terminal device is located are consistent, the reported location information may be determined to be reliable, and when the identifiers of the cells in which the terminal device is located are inconsistent, the reported location information may be determined to be unreliable.

The second threshold may be agreed by a protocol, or may be preset in the system, which is not limited in this disclosure.

Optionally, if the difference between each reported position and the reference position is greater than or equal to the second threshold value within the preset time period, it is indicated that the reported position and the reference position are different greatly, so that it can be determined that the reported position information is unreliable.
