Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a terminal 11 and a first communication device 12. Wherein, the terminal 11 may also be called as a terminal Device or a User Equipment (UE), the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer) or a notebook Computer, a Personal Digital Assistant (PDA), a palmtop Computer, a netbook, a super-Mobile Personal Computer (UMPC), a Mobile Internet Device (MID), a Wearable Device (Wearable Device) or a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), and other terminal side devices, the Wearable Device includes: bracelets, earphones, glasses and the like.

The core network device may be a location server, LMF, E-SMLC, or some other suitable terminology in the art.
In a research project named "5G new air interface in' Non-terrestrial network oriented" in the third generation mobile communication partnership project (3GPP), a deployment scenario of a Non-terrestrial network (NTN) including a satellite network is defined. As one of multiple access technologies of a fifth generation mobile communication system (5th generation mobile networks, 5G) and a later 5G mobile communication system (B5G), a satellite can provide a low-cost coverage scheme in a ground network coverage weak area, and has obvious advantages in some industrial application scenarios requiring wide area coverage.
In the NTN scenario, the requirements of the UE location information are as follows:
since handover generally occurs when a UE or a relay node is in a Connection Management (CM) active state and a Radio Resource Control (RRC) connected state, the procedure is time-critical in order to avoid data loss. In NTN systems, cells or spot beams move at high speeds and therefore handover procedures from one spot beam to the next or from one satellite to the next must be performed quickly, otherwise the UE may not be able to efficiently utilize the target beam and/or satellite resources and, in the worst case, may lose data.
In a non-geostationary satellite access network, a UE resides under one satellite beam, but the beam is constantly moving, and over time the UE may constantly reside in a different satellite and in a different beam, even if the UE is stationary. Unlike terrestrial Network architectures where terrestrial cells are associated with a Radio Access Network (RAN) by wireless communications, in a non-geostationary satellite Access Network, the satellite beam is moving. The terrestrial cell has no correspondence with the satellite beam. Over time, the same cell may be covered by different satellites and different beams.
Therefore, for the initial registration process, the satellite-based radio Access network cannot provide Access and Mobility Management Function (AMF) information from a certain satellite or Tracking Area (TA) on a certain beam that received the registration request. But this tracking area information is crucial for the UE to decide whether a registration area update with the AMF is required.
For the acquisition of the terminal positioning information, the terminal positioning information can be generally obtained by a Global Navigation System (GNSS). However, we cannot assume that all terminals are configured with the global positioning system, and ephemeris information of the global positioning system is known, so that it cannot be guaranteed that a positioning result is safe and reliable and is not tampered. Under the NTN scenario, there is no complete feasible scheme for safely and reliably acquiring the terminal positioning information.
