s1110: measuring TN cells;

s1120: and transmitting the cell identification of the TN cell to an NTN base station.

The UE may be various types of terminal devices, such as a cell phone, a tablet computer, a wearable device, a smart home device, a smart office device, or a vehicle-mounted device.

The UE is currently accessing the NTN. The satellite cell is one of NTN cells. Since one satellite cell typically has a large coverage area, it may cover both the areas of country a and country B, and both network operators may share the satellite access, while the regulations of country B require that its national UEs be strictly prohibited from accessing the home operator network in a non-roaming manner. At this time, if the user in country a located in the border area accesses the network of country B through the satellite access selection, the network device (for example, AMF) of the operator in country B verifies the UE location, determines whether the user is located in country B, and if not, prohibits the user from directly accessing (in a non-roaming manner) the network in country B.

In the embodiment of the disclosure, the UE may measure the TN cell, and the coverage area of the TN cell is relatively small, so the cell identifier of the TN cell measured by the UE may be used to represent the current location of the UE.

In the embodiment of the disclosure, the UE performs measurement of the TN cell without accessing the TN cell. Illustratively, the UE measures various broadcast information and/or broadcast signals of the TN-cell. Further exemplary, the broadcast information includes, but is not limited to, a system message. The broadcast signals include, but are not limited to, synchronization signals, or cell-level signals such as channel state information reference signals. The UE completes the measurement of the TN cell under the conditions of accessing the NTN and not accessing the TN, so that the problem that the TN cell information cannot be acquired under the condition of accessing the NTN because the UE cannot use a plurality of 3GPP accesses (NTN and TN) simultaneously in the related technology can be solved.

In the embodiment of the disclosure, the UE may send the measured cell identifier of the TN cell to the NTN base station, so as to facilitate network devices such as the NTN base station, verify whether the location information provided by the UE is trusted, or obtain the trusted location information of the UE in this way.

In one embodiment, after the UE accesses the NTN, actively measuring the TN-cell; or the UE synchronously measures TN cells before or when the UE accesses the NTN, and the cell identification of the measured TN cells is sent to the NTN base station in the NTN access process or after the UE accesses the NTN.

In some embodiments, the UE measuring TN-cells is triggered by measurement request information sent by the NTN base station.

The indication information comprises one or more bits, and when the one or more bits are a preset value, the UE determines that the network equipment indicates the network equipment to measure TN cells.

For example, if the indication information indicates that the location of the UE needs to be verified, the UE may measure the TN cell and report the measured cell identifier of the TN cell to the NTN base station.

The location information reported by the UE includes, but is not limited to: longitude and latitude information of the UE, etc.

s1320: and transmitting the cell identification of the TN cell to an NTN base station.

In some embodiments, the UE may periodically measure the TN cells in consideration of mobility of the UE, so that the network of the NTN may periodically obtain trusted location information of the UE.

In other embodiments, the UE may measure TN-cells upon detecting its own movement event.

Illustratively, the UE moves a distance within a unit time to reach a distance threshold, or the UE moves a speed to reach a speed threshold. Since the UE moves to perform the measurement of the TN cell, on one hand, the change of the UE position caused by the mobility of the UE is considered, and on the other hand, unnecessary measurement of the UE is reduced. In some embodiments, the measuring land cellular network TN cell comprises:

monitoring broadcast messages of the TN cell;

and/or the number of the groups of groups,

and measuring the cell signals of the TN cell.

The broadcast message and the cell signal may be sent on a broadcast channel of the TN cell, and the UE monitors the broadcast channel of the TN cell, so that the broadcast message and/or the broadcast signal carrying the cell identifier may be received.

The broadcast message and/or broadcast signal of the TN-cell may be any broadcast message and/or broadcast signal of the related art, for example, a synchronization signal block, etc.

In short, if the UE monitors the broadcast message and/or the cell signal of the TN cell, the measurement of the TN cell may be completed without accessing the TN cell.

In the embodiment of the disclosure, if the broadcast message of the TN cell is successfully monitored and/or the cell signal is measured, the broadcast message is not required to be completely decoded successfully and/or the signal receiving quality of the cell signal reaches the expected quality, and if the cell identifier of the TN cell is successfully obtained, the corresponding TN cell can be considered to be measured.

In some embodiments, the cell identity of the TN cell is used for the network device to verify whether to allow the UE to access the public land mobile network (Public Land Mobile Network) PLMN selected by the UE at the current location based on the cell identity of the TN cell.

Illustratively, the cell identity of the TN cell is used by the network device to verify whether the current location of the UE allows the UE to access its selected PLMN. In this manner, the network device may determine whether to allow the UE to access the PLMN selected by the UE based on the trusted location information of the UE.

In some embodiments, the method further comprises:

receiving a de-registration message;

and initiating the deregistration process according to the deregistration message.

Here from core network equipment including, but not limited to, access management functions (Access Management Function, AMF).
