[0050] In the above embodiment, when the terminal and / or the non-terrestrial network NTN radio access network RAN ​​does not support the network-assisted positioning capability based on NTN, the first core network device cannot verify the location of the terminal. At this time, the first core network device will send a first information to the terminal indicating that the first core network device cannot verify the location of the terminal and / or the reason why the location of the terminal has not been verified. In this way, after receiving the first information, the terminal can clearly determine the reason why the location has not been verified and clearly define the actions that can be executed.

The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0140] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0144] In some embodiments, during initial registration or mobility update registration, when the Access and Mobility Management Function (AMF) receives a Protocol for NG Interface (NGAP) message containing user location information of a terminal using satellite access, the AMF can determine the verified terminal location.

[0145] In some embodiments, if the AMF determines that the terminal is not allowed to operate at the current location based on the selected PLMN identity (ID) and user location information (ULI) (including cell identity) received from the base station (gNB), the AMF shall reject any non-access stratum (NAS) request (e.g., registration request, PDU session establishment request) and set the corresponding cause value #78 to "Terminal is not allowed to access the PLMN at the current location". If the terminal is already registered with the network when the AMF determines that the terminal is not allowed to operate at the current terminal location, the AMF may initiate deregistration of the terminal.

[0146] In some embodiments, the terminal should store the PLMN identity, if known, and should store the current geographical location in a list of "PLMNs that are not allowed to be accessed at the terminal's current location".

[0147] In some embodiments, if the current terminal location is known, the PLMN entry stores a geographical location, and the distance from the address location to the current terminal location is greater than a configured specific value, the UE may delete the entry from the list.

[0148] In some embodiments, if the user is in the 5GMM-DEREGISTERED and LIMITED-SERVICE states and the entry is deleted from the list of PLMNs not allowed to operate in the terminal's current location, the terminal can perform PLMN selection. At this time, the UE will enter the 5GMM-DEREGISTERED.PLMN-SEARCH state and perform PLMN selection.

[0149] In some embodiments, the cause value #78 "PLMN not allowed access at current UE location" applies only to cases where the UE has been verified not to be accessible at the current location. However, if the AMF or Mobility Management Entity (MME) rejects any NAS request from the terminal because the terminal and / or RAN do not support network-assisted positioning capabilities and cannot obtain the terminal's trusted location and therefore cannot perform location verification, then the cause value #78 defined for terminals using satellite access is obviously not suitable for this case, and there is no cause value that can notify the terminal of the corresponding event.

[0150] In some embodiments, if a terminal user is located in Country A and is not permitted to access the network in Country B in a non-roaming manner, when the terminal user accesses a satellite cell that provides coverage for both Country A and Country B, the terminal user may still be able to access the network in Country B through the satellite cell, which does not comply with regulatory requirements. Verification is required as to whether the user is located in Country A or Country B. If the user is located in Country B, network access should be prohibited at the user's current location.

[0151] To ensure that regulatory requirements are met, the core network may apply location verification to determine whether a terminal using satellite access is allowed to access the Public Land Mobile Network (PLMN) at its given location.

As shown in Figure 5a, the present disclosure embodiment relates to an information indication method, which is used in a communication system 100 and includes one of the following steps:

[0300] Step S5101: The first core network device sends first information to the terminal;

[0301] In some embodiments, the first information indicates that the first core network device cannot verify the location of the terminal and / or the reason why the location of the terminal is not verified; the terminal and / or NTN RAN does not support NTN-based network-assisted positioning capabilities, and the first core network device cannot verify the location of the terminal.

[0302] The optional implementation of step S5101 can refer to the optional implementation of step S2104 in Figure 2a and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0303] In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, core network device side, etc., which will not be repeated here.

[0304] In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through an exemplary embodiment:

[0305] In some embodiments, if the AMF or MME obtains information that the UE and / or RAN does not support network-assisted positioning capabilities (corresponding to the second information and / or the third information), it is impossible to perceive whether the UE location is reliable. Therefore, it is impossible to perform location verification for terminals accessing the PLMN using satellite access.

[0306] In some embodiments, for a UE using satellite access, when the AMF or MME is unable to perform location verification because the UE and / or RAN does not support network-assisted positioning capabilities, then:

[0307] The AMF rejects any NAS request from the UE or accepts UE access (for example, allows UE access with limited services). The message sent to the terminal includes a cause value indicating that the current location of the terminal is not verified (corresponding to the first information).

[0308] In some embodiments, based on the received cause value, the terminal may stop using satellite access or stop using satellite access to access the PLMN.

[0309] In some embodiments, the reason value can be refined as follows:

[0310] If the cause value indicates that the terminal's location was not verified because the terminal does not support network verification positioning capabilities:

[0311] If the terminal receives a rejection message with a cause value, the terminal stops trying to access the PLMN via satellite access;

[0312] If the terminal receives an accept message with a cause value, the terminal accesses the PLMN via satellite access.

[0313] If the cause value indicates that the terminal's location was not verified because the RAN serving the terminal does not support network-assisted positioning capabilities:

[0314] If a reject message with a cause value is received, then stop trying to access the PLMN via the currently serving RAN node;

[0315] If the RAN node serving the UE changes, the UE will initiate access to the PLMN via satellite access;

[0316] If the terminal receives an accept message with a cause value, the terminal accesses the PLMN via satellite access.

[0317] Figure 6a is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in Figure 6a, the embodiment of the present disclosure relates to an information indication method, which includes:

[0318] Step S6101: The terminal initiates a registration request via satellite access. If the terminal supports network-verified positioning technology (corresponding to support for network-assisted positioning capability), it indicates this capability to the AMF (corresponding to sending a second message).

[0319] Step S6102: The serving RAN node sends an NGAP message to the AMF. The NGAP message may include the terminal's current location information (contained in the ULI) from GNSS measurements and the terminal's selected PLMN. Furthermore, if the serving RAN node supports network-assisted positioning methods, the RAN also notifies the AMF of its capabilities. If this capability is not included in the message, it indicates that the serving RAN node does not support network-assisted positioning methods.

[0320] Step S6103: Send a cause value. The AMF can determine the location verification of the terminal access through satellite access. However, the serving RAN node does not support the network-assisted positioning method, and the AMF cannot determine whether the terminal's location is reliable. The AMF may return a registration reject message (corresponding to the first information) to the terminal, which contains a cause value indicating that the terminal location has not been verified because the serving RAN node does not support network-verified positioning. After receiving the rejection message with the cause value, the UE stops trying to access the PLMN through the RAN node. If the RAN node changes, it may cause the terminal to retry accessing the PLMN.

[0321] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0322] FIG6b is an interactive diagram of an information indication method according to an embodiment of the present disclosure. As shown in FIG6b , the embodiment of the present disclosure relates to an information indication method, and the method includes:

[0323] Step S6201: The terminal initiates a registration request via satellite access. If the terminal supports the positioning technology verified by the network, it indicates this capability to the AMF (corresponding to the second information).

[0324] Step S6202: NR-RAN sends an NGAP message to AMF. The current location information of the terminal from GNSS measurement (contained in the ULI) and the PLMN selected by the terminal may be included in the message. The NGAP message may indicate whether the RAN supports network-assisted positioning capabilities (corresponding to the third message)

[0325] Step S6203: If the AMF based on the user location information ULI cannot determine the UE's location with sufficient accuracy to make a final decision whether to allow the UE to access at its current location, or if the received ULI is not reliable enough, the AMF first accepts the UE's registration.

[0326] Step S6204: The UE requests to establish a PDU session associated with the applicable regulatory service.

[0327] Step S6205: If the terminal supports network-assisted positioning capability, the AMF decides to trigger location verification of terminal access.

[0328] Step S6206: The AMF selects a LMF and calls the Nlmf_Location_DetermineLocation service operation to request the current location of the UE from the LMF. The service operation includes the location request indication from the regulatory service client and the AMF identifier (corresponding to the fifth information).

[0329] Step S6207: The LMF uses the NG-RAN to perform a network-assisted positioning procedure based on NTN to obtain the current location of the UE. During this process, if the RAN does not support network-verified positioning, a positioning failure may be returned, indicating that the RAN does not support network-assisted positioning based on NTN.

[0330] Step S6208: The LMF returns an Nlmf_Location_DetermineLocation response to the AMF. Service Operation Description: Because the RAN does not support NTN-based network-assisted positioning, the terminal's current location fails to be acquired (corresponding to the sixth information).

[0331] Step S6209: Send cause value. Since the AMF did not receive the terminal location information through the LMF, the terminal location verification failed. According to the operator's policy (corresponding to the first policy), the AMF may deny user access. The AMF uses the cause value to start the UE deregistration process, which indicates that the UE location is not verified because the serving RAN node does not support network verification positioning. After receiving the deregistration message with the cause value, the terminal performs the deregistration operation. The UE can try to access the PLMN through TN access, or if the RAN node for satellite access changes, the UE can try to access the PLMN through satellite access again.
