One base station may form one or more cells. And typically the geographic area range to which the cell corresponds is fixed.

And if the UE requests access to the NTN, a registration request message is sent to the access equipment of the NTN. The registration request message of the UE requesting access to the NTN carries indication information about whether the UE supports access to the TN, so if the NTN wants to verify whether the position information reported by the UE is reliable, the position information reported by the UE can be verified to be reliable according to the access position of the UE in the TN, thereby reducing the phenomena that various service quality based on the position information is poor or specific service is provided for the UE which is not in the specific position caused by the unreliability or the error of the position information reported by the UE.

In some embodiments, the registration request message further includes: first location information of the UE.

The first location information may include any information indicating a location of the UE.

Illustratively, the first location information may include, but is not limited to: positioning information of the UE. For example, the positioning information includes, but is not limited to, latitude and longitude of the UE, or relative position information with respect to a reference position on the ground.

The registration request message includes: the first location information of the UE may be used by a network element at the network side to select an access device of the TN, which may be accessed by the UE, for access by the UE when the UE leaves the coverage area of the NTN.

As shown in fig. 3, an embodiment of the present disclosure provides an information processing method, wherein the method is performed by a UE, and includes:

s1210: transmitting a registration request message to an access device of the NTN, wherein the registration request message includes: the UE supports the indication information of whether to access to the ground network TN;

s1220: receiving a registration response message sent by an access device of NTN;

s1230: and sending a registration request message to the access equipment of the TN according to the registration response message.

If the UE supports TN registration (or called access), after receiving the registration request message of the UE, the first core network device of the NTN may need to verify whether the first location information carried in the registration request message or the first location information reported by the UE with a message other than the registration request message is trusted, and then the UE receives a registration response message returned by the network element of the NTN.

The registration response message may include: a registration acceptance message indicating that the first core network device of the NTN temporarily accepts registration, or a registration rejection message indicating that the NTN temporarily does not accept registration. The first core network device includes, but is not limited to: AMF of NTN.

After receiving the registration acceptance message, the UE may send a registration request message to the access device of the TN. If the UE sends a registration request message to the access device of the TN, the base station of the TN receives the registration request message sent by the UE, and may transmit the base station identifier of the base station and/or the cell identifier of the UE sending the registration request message to the core network device of the TN, so that the first core network device of the NTN may obtain, through the connection between the first core network device of the NTN and the third core network device of the TN, the base station identifier and/or the cell identifier of the UE requesting access, where the base station identifier and/or the cell identifier may be used to verify the reliability and/or accuracy of the first location information included in the registration request message.

In some embodiments, the method further comprises:

and when the registration response message returned by the NTN does not contain the position verification indication and/or the TN registration indication, the UE determines that the UE is currently registered to the NTN and uses the NTN to develop the service according to the service requirement.

In some embodiments, the sending the registration request message by the access device of the ground network TN further comprises: registration cause indication for location verification.

In some embodiments, the registration request message may carry an indication of the registration cause.

The registration cause indication may indicate a cause for the UE to request registration to the TN. For example, in some embodiments, the registration cause indication may indicate that the UE requests a trigger service to register with the TN.

In the embodiment of the disclosure, if the registration cause indicates, the registration cause indication may be used for the UE to request location verification.

For example, if the registration response message received from the access device of the NTN includes a location verification indication and/or a TN registration indication, a registration request message indicating a registration cause indication of the location verification is sent to the access device of the TN.

If the registration request message sent to the TN access device includes a registration cause indication indicating location verification, the third core network device of the TN will know the cause of the UE currently requesting registration to the TN. The "third" of the "third core network device" is described herein only for distinguishing between different core network devices, and is not limited in nature. The third core network device may be an AMF of a TN or the like.

In some embodiments, the method further comprises:

the registration request message sent to the access device of the TN includes the registration reason indication of the location verification, and the access device of the TN receives a registration rejection message returned after the first core network device of the NTN completes the first location information verification on the UE.

If the UE initiates a registration request message to the access device of the TN to trigger the registration procedure of the UE in the TN, only for location verification, and the network side knows that the UE requests the base station and/or the cell to be accessed, the third core network device of the TN can reject the registration of the UE to access the TN, and the UE will receive a registration rejection message sent by the access device of the TN. The registration rejection message may be received from a third core network device of the TN, and the access device of the TN may forward to the UE.

The registration rejection message is used for informing the UE to reject access registration of TN.

If the UE is refused to access the registration of the TN, the UE is not required to be registered to the NTN and the TN at the same time, the power consumption generated by the UE connected to the TN and the NTN at the same time is reduced, and the standby time of the UE is verified.

As shown in fig. 4, an embodiment of the present disclosure provides an information processing method, where the method is performed by a first core network device of an NTN, and the method includes:

s2110: receiving a registration request message of UE sent by the access equipment of the NTN; wherein the registration request message includes: and indicating information of whether the UE supports access to the ground network TN.

The first core network device of the NTN includes, but is not limited to: AMF.

The AMF of the NTN is responsible for the access and mobility management of the UE in the NTN, so that a registration request message sent by the UE to the access device of the NTN is transmitted by the access device of the NTN to the first core network device such as the AMF of the NTN.

When the first core network device receives the registration request message, the first core network device obtains that the registration request message contains the indication information.

And the indication information indicates that the UE supports access to the TN, or indicates that the UE does not support access to the TN.

If the indication information indicates that the UE supports access to the TN, it is indicated that the first core network device may use the access location of the UE in the TN to verify the reliability and/or accuracy of the first location information submitted by the UE.

If the first core network device of the NTN determines that the service based on the location information needs to be provided to the UE, or if it needs to be determined whether to allow the UE to access according to the location information of the UE, and the indication information indicates that the UE supports access to the TN, the first location information provided by the UE may be verified by means of the access location of the UE in the TN, and after the first location information provided by the UE is verified to be trusted, the UE is finally allowed to access the NTN or to perform the service based on the location information based on the NTN.

As shown in fig. 5, an embodiment of the present disclosure provides an information processing method, where the method is performed by an NTN first core network device, and the method includes:

s2210: receiving a registration request message of UE sent by access equipment of a non-terrestrial network (NTN); wherein the registration request message includes first location information of the UE;

s2220: and based on the access position of the UE in the TN, verifying whether the first position information of the UE is credible.

The access location may be indicated by a base station identity of an access base station of the UE at TN and/or a cell identity of an access cell.

Illustratively, verifying whether the first location information of the UE is authentic based on the access location of the UE at the TN may include at least one of:

When the access position of the TN and the UE position indicated by the first position information belong to different cells, determining that the first position information of the UE is not trusted;

when the access position of the TN and the UE position indicated by the first position information belong to the same cell, determining that the first position information of the UE is credible;

when the distance between the access position of the TN and the UE position represented by the first position information is smaller than or equal to a distance threshold value, determining that the first position information of the UE is credible;

and when the distance between the access position of the TN and the UE position represented by the first position information is larger than the distance threshold value, determining that the first position information of the UE is not trusted.

In some embodiments, the base station of TN may further estimate the distance between the UE and the base station based on the measured value of the reference signal sent by the base station. The measurements include, but are not limited to: reference signal received power (Reference Signal Receiving Power, RSRP) and/or reference signal received quality (Reference Signal Received Quality, RSRQ). Since the power of the reference signal transmitted by the base station is known, the propagation loss of the reference signal in the air can be estimated, and thus the distance between the UE and the base station can be estimated based on the received power and/or the received quality of the reference signal. The distance information of the distance can also be queried by network elements of the NTN from the TN network side, so that AMF of the NTN can verify whether the first position information reported by the UE is credible or accurate according to the access position of the UE and the distance information of the estimated distance. Of course, the above is merely an illustration of the verification of the first location information by the AMF of the NTN, and the specific implementation is not limited to the above illustration.

Illustratively, the AMF of the NTN may directly request the second location information of the access location of the UE and/or the distance information from the AMF of the TN through a connection with the AMF of the TN.

After the first core network device receives the identification information of the UE, the first core network device queries second location information of the access location reported by the UE when the UE accesses the TN.

And returning the second position information to the first core network equipment of the NTN, so that the first core network equipment of the NTN can verify whether the first position information reported by the UE is credible or accurate.

In one embodiment, the first core network device of the NTN may send a registration message to the second core network device directly after receiving the registration request message that the UE requests to register with the NTN, and enter into a wait for the second location information returned by the second core network device. In some embodiments, wherein the method further comprises:

In other embodiments, the first core network device of the NTN sends a registration response message to the UE before receiving the second location information, the registration response message being used to trigger the UE to request access to the TN.

In this case, the first core network device of the NTN may simultaneously request the second location information from the second core network device when transmitting the registration response message to the UE. Or after sending the registration response message to the UE, requesting the second location information from the second core network device, or after sending the registration message requesting the second location information to the second core network device, sending the registration response message to the UE. That is, the first core network device of the NTN sends the registration response message to the UE and requests the second location information to the second core network device in no certain sequence, and the method can be arbitrarily executed.

In some embodiments, if the first core network device of the NTN sends the registration response message to the UE after receiving the second location information and completing the verification of the first location information, it may determine whether to allow the UE to access the NTN according to the verification result of the first location information, and send a registration accept message or a registration reject message to the UE according to the determination result of whether to allow the UE to access the NTN.

In some embodiments, if the registration response message is used to trigger the UE to access to the TN, the registration response message may include: a location verification indication.

The location verification indication may trigger the UE to request registration to the TN, specifically, trigger the UE to send a registration request message to the TN.

In other embodiments, the registration response message triggering the UE to access the TN may further include: TN registration indication.

Illustratively, the second location information includes: and the UE accesses the cell global identifier of the TN.

As shown in fig. 8, an embodiment of the present disclosure provides an information processing method, where the method is performed by a second core network device, and the method includes:

s3110: receiving a registration message sent by first core network equipment of the NTN;

S3120: and sending second position information to the first core network equipment of the NTN according to the registration message, wherein the second position information indicates the access position of the UE to the TN and is used for the first core network equipment of the NTN to verify whether the first position information of the UE is credible or not.

The second core network device includes, but is not limited to, a UDM. The UDM may be a data management DM common to NTN and TN.

In this way, a connection is established between the first core network device of the NTN or the first core network device of the TN and the UDM, and user data of UEs registered with the TN and NTN are maintained at the same time.

If the registration message sent by the first core network device of the NTN is received, the second core network device sends second location information to the first core network device, and after the second location information is returned to the first core network device of the NTN, the first core network device of the NTN verifies whether the first location information of the first core network device F reported to the NTN by the UE is trusted and/or accurate according to the second location information.

If the UE accesses the TN before a period of time when the UE requests to access the NTN, and the time difference between the access time of the UE at the TN and the receiving time of the registration message sent by the first core network device of the UDM receiving the NTN is short, it is considered that the UE is movable but has a small moving range. Therefore, the second location information can be directly sent to the first core network device of the NTN according to the access location of the TN at the registration time when the time difference satisfies the preset condition without triggering the UE to re-register to the TN.

The time difference between the receiving time of the registration message and the registering time of the UE accessing to TN meets the preset condition, including:
