[0070] To better understand the technical solution of this application, the following contents are first introduced:

[0071] About NTN

[0072] Non-terrestrial networks refer to networks or network segments that use satellite or unmanned aircraft system (UAS) platforms for transmission. Compared with terrestrial communication systems, satellite-based non-terrestrial communication systems have a wider coverage area. Typical applicable scenarios include situations where ground base stations cannot be built or are damaged, such as continuous coverage in remote mountainous areas, deserts, oceans, and forests, and emergency communications when ground base stations are damaged due to natural disasters.

[0073] Satellites: including Low Earth Orbiting (LEO) satellites, Medium Earth Orbiting (MEO) satellites, Geostationary Earth Orbiting (GEO) satellites and Highly Elliptical Orbiting (HEO) satellites.

[0074] Typical scenarios of non-terrestrial networks include transparent forwarding, where the satellite acts as a forwarding relay. As shown in Figure 1b, the link between the satellite and the terminal is the service link, and the link between the satellite and the ground base station is the feedback link.

[0075] Coarse UE location reporting

[0076] The 3rd Generation Partnership Project (3GPP) supports bandwidth reduced low complexity (BL) UE, UE in Coverage Enhancement (UE inCE) and narrowband Internet of Things (NB-IoT) UE to access the NTN, where BL UE and UE in enhanced coverage are collectively referred to as enhanced Machine-Type Communication (eMTC) terminals.

[0077] When a terminal accesses the network through a cell, the radio access network determines the tracking area where the terminal is located based on the selected network information reported by the terminal, and informs the core network of this information so that the core network can perform mobility management. In satellite communication systems, a cell provides multiple tracking area codes (TACs) for each network supported by the cell. When a terminal accesses the network through a cell, the radio access network cannot determine the tracking area where the terminal is located, and thus cannot provide accurate tracking area information to the core network, which is not conducive to the core network's mobility management. Therefore, the terminal is introduced to report location information to the radio access network, so that the Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN) determines the tracking area (TA) and mapped cell ID of the terminal based on the terminal's reported location information, and indicates this information to the core network so that the core network can perform mobility management.

[0078] For eMTC terminals, coarse UE location reporting is supported. The terminal can report its location in the following two ways:

[0079] Measurement reporting: If the measurement report of the terminal is triggered and the reporting configuration corresponding to the measurement ID corresponding to the measurement report is configured with coarseLocationReq, the terminal includes coarseLocationInfo in the measurement report.

[0080] UE information procedure: If the UEInformationRequest message received by the terminal includes coarseLocationReq, the terminal includes coarseLocationInfo in the UEInformationResponse message.

[0081] In NTN, it is crucial for the network to know the location information of the terminal, for example, to assist the network in mobility management. Since sending location information via RRC signaling requires AS security, and NB-IoT devices with support for CP CIoT EPS Optimization only do not have AS security, and considering user privacy concerns, the current mechanism for terminals to report location information is only applicable to eMTC UEs, not NB-IoT UEs. In addition, allowing the network to obtain the terminal's location information as early as possible (for example, when the initial connection is established) is also helpful for the network to determine whether to allow services to the terminal. However, AS security is not activated before the initial connection is established, and reporting location information before the initial connection is established is currently not supported.

[0082] Therefore, how to support the terminal to report location information in the absence of AS security is a problem that needs to be solved. It should be noted that the problem of how the terminal reports location information in the absence of AS security is not limited to a specific terminal type, and the problem needs to be solved for all existing terminal types.

[0083] The method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0084] Referring to FIG. 2 , an embodiment of the present application provides a method for reporting location information, which is executed by a terminal and includes:

[0085] Step 201: The terminal obtains first information;

[0086] Step 202: The terminal sends the location information of the terminal to the core network device according to the first information;

[0087] The location information of the terminal is included in a first non-access stratum (NAS) message.

[0088] The above-mentioned first information may be indication information received by the terminal, used to instruct the terminal to report location information, or the above-mentioned first information may be capability information of the terminal itself, used to determine whether the terminal has the capability to report location information, or the above-mentioned first information may be type information of the terminal itself, used to determine the type of the terminal.

[0089] The location information of the terminal may specifically be Global Navigation Satellite System (GNSS) location information.

[0090] Optionally, the location information of the terminal includes at least one of the following types:

[0091] (1) GNSS position, such as longitude and latitude;

[0092] (2) GNSS position of specified accuracy, such as imprecise latitude and longitude;

[0093] (3) Address information (e.g., a certain street, a certain building, a certain square, etc.);

[0094] (4) Other information that can represent the geographical location of the terminal.

[0095] In the embodiment of the present application, the terminal reports its location information to the core network via NAS messages. In this way, even if AS security is not used or activated, the terminal's location information can still be reported via NAS messages to assist the network side in performing processes such as mobility management or UE location verification.

[0096] In one possible implementation, the first information includes at least one of the following:

[0097] (1) First indication information: The first indication information is used to instruct the terminal to report its location information. The first indication information is received by the terminal from the core network device via a second NAS message. That is, when the core network device instructs the terminal to report its location information via the second NAS message, the terminal reports its location information via the first NAS message. Optionally, the first indication information may also indicate the accuracy of the location information reported by the terminal, such as coarse granularity or fine granularity.

[0098] (2) First capability information: The first capability information is used to indicate whether the terminal supports the ability to report the terminal's location information through a NAS message; that is, when the terminal has the ability to report the location information through a NAS message (in this case, no instruction from the core network is required), the terminal reports the location information through the first NAS message.

[0099] (3) First terminal type information: The first terminal type information is used to indicate that the terminal is an NB-IOT terminal. That is, when the terminal is specifically an NB-IOT terminal (in this case, no indication from the core network is required), the terminal reports the location information through the first NAS message.

[0100] The above (1) to (3) clarify the circumstances under which the terminal can report location information to the core network through NAS messages.

[0101] In one possible implementation, the first NAS message includes any one of the following:

[0102] (1) Attach complete message;

[0103] (2) Registration complete message;

[0104] (3) Service request message (service request);

[0105] (4) Packet Data Network Connection (PDN) establishment request message;

[0106] (5) Protocol Data Unit (PDU) session establishment request message;

[0107] (6) A dedicated NAS message for reporting the terminal's location information, that is, constructing a new NAS message dedicated to reporting the terminal's location information.

[0108] By carrying the location information of the terminal through the interactive messages (1) to (6) above, the reporting of the location information is completed in the interactive process corresponding to the above messages.

[0109] In a possible implementation manner, the second NAS message includes any one of the following:

[0110] (1) Attach request accept message (attach accept);

[0111] (2) Registration request acceptance message (registration accept);

[0112] (3) A dedicated NAS message for instructing the terminal to report location information, that is, constructing a new NAS message dedicated to instructing the terminal to report location information.

[0113] By carrying the instruction information for instructing the terminal to report the terminal's location information through the interaction messages (1) to (3) above, the instruction for the terminal to report the terminal's location information is completed in the interaction process corresponding to the above messages.

[0114] In a possible implementation, when the first information is the first indication information, the terminal sends the first NAS message to the core network device according to the first information, including:

[0115] (1) After receiving the first indication information, the terminal determines whether to agree to report the terminal's location information, or whether the terminal's location information is valid, or whether the terminal supports the capability of reporting the terminal's location information through a NAS message;

[0116] (2) When it is determined that the user of the terminal agrees to report the terminal's location information, or when it is determined that the terminal's location information is valid, or when the terminal supports the capability of reporting the terminal's location information through a NAS message, the terminal's location information is sent to the core network device.

[0117] In an embodiment of the present application, after the terminal receives the indication information sent by the core network to instruct the terminal to report the terminal's location information, the terminal needs to first determine whether its own user agrees to report the location information, or whether its own location information is valid, or whether the terminal supports the ability to report the terminal's location information through a NAS message. When it is determined that the user agrees to report the terminal's location information, or that the terminal's location information is valid, the terminal reports the location information through a first NAS message.

[0118] In a possible implementation, after receiving the first indication information, the terminal determines whether to agree to report the terminal's location information, or determines whether the terminal's location information is valid, including:

[0119] After receiving the first indication information, the terminal determines at least one of the following based on the second information:

[0120] (1) Whether to agree to report the terminal's location information;

[0121] (2) Whether the terminal's location information is valid;

[0122] (3) Whether the terminal supports the ability to report the terminal's location information through NAS messages;

[0123] The second information is used to indicate whether the user of the terminal agrees to report the location information of the terminal, or to indicate the validity of the location information of the terminal, or to indicate whether the terminal supports the capability of reporting the location information of the terminal through a NAS message.

[0124] In one possible implementation, the method further includes:

[0125] When the second information indicates that the user of the terminal does not agree to report the location information of the terminal, or indicates that the location information of the terminal is invalid, or the terminal does not support the ability to report the location information of the terminal through a NAS message, sending the second indication information to the core network device;

[0126] The second indication information is used to instruct the terminal not to report the location information of the terminal or to refuse to report the location information of the terminal.

[0127] When the user of the terminal does not agree to report the location information, or the current location information is unavailable or invalid, or the terminal does not support the ability to report the terminal's location information through a NAS message, the terminal does not send the UE's location information, and the terminal may send an indication message to the core network that the terminal does not report the terminal's location information;

[0128] In a possible implementation manner, the second information is carried in the first NAS message.

[0129] Optionally, the second indication information may further include the reason why the terminal does not report the location information, such as privacy issues, invalid location or unavailable location.

[0130] In one possible implementation, the method further includes:

[0131] The terminal sends a first request message to the core network device, where the first request message includes the first capability information or the second capability information;

[0132] The second capability information is used to indicate that the terminal does not support the capability of reporting the terminal's location information through a NAS message, and the first request message is used to request attachment or registration.

[0133] The terminal can send its ability to support or not support reporting the terminal's location information through NAS messages to the core network through a request message during the attachment / registration request phase. The core network can decide whether to send the first NAS message to instruct the terminal to report the location information based on the terminal's capability.

[0134] Referring to Figure 3, an embodiment of the present application provides a method for receiving location information. The execution subject of the method is a core network device, such as an MME or AMF. The embodiment of the present application does not limit the type of core network device, including:

[0135] Step 301: The core network device receives the terminal's location information from the terminal;

[0136] The location information of the terminal is included in the first NAS message.

[0137] Optionally, the core device receives the location information of the terminal through the first NAS message, which can be executed after the core network instructs the terminal to report the location information through the NAS message, or the core device does not instruct the terminal, and the terminal actively reports the location information to the core device based on its own capabilities or type.

[0138] In a possible implementation, before the core network device receives the location information of the terminal from the terminal, the method further includes:

[0139] The core network device sends first indication information to the terminal;

[0140] The first indication information is included in the second NAS message, and the first indication information is used to instruct the terminal to report the location information of the terminal.

[0141] The core network instructs the terminal to report the location information through the second NAS message. After receiving the instruction, the terminal reports the location information to the core network device through the first NAS message.

[0142] In a possible implementation, before the core network device receives the location information of the terminal from the terminal, the method further includes:

[0143] The core network device receives first capability information from the terminal, where the first capability information is used to indicate a capability of the terminal to support reporting the terminal's location information through a NAS message.

[0146] (2) Registration request message;

[0147] (3) A dedicated NAS message for sending the first capability information, that is, constructing a new NAS message dedicated to reporting the first capability information.

[0162] (1) Attach request accept message (attach accept);

[0163] (2) Registration request acceptance message (registration accept);

[0167] The core network device receives second indication information from the terminal;

[0168] The second indication information is used to instruct the terminal not to report the location information of the terminal.

[0169] The terminal side determines whether to report the location information based on whether its own user agrees or whether the current location information is valid. When it is determined not to report the location information, the terminal instructs the core network device not to report the terminal's location information.

[0170] In one possible implementation, the method further includes:

[0171] The core network device determines the area information of the terminal according to the mapping relationship between the terminal's location information and the pre-configured area information.

[0172] In the case where the core network device receives the location information of the terminal, the core network device may determine the area information of the terminal based on a mapping relationship between the location information of the terminal and pre-configured area information.

[0173] The terminal area information may include at least one of the following:

[0174] (1) The Tracking Area Code (TAC) or Tracking Area Identity (TAI) corresponding to the terminal's location;

[0175] (2) The mapped Cell ID corresponding to the terminal's location, i.e., the Cell ID corresponding to the fixed ground area;

[0176] (3) The Cell Global Identity (CGI) corresponding to the terminal's location.

[0177] The above mapping relationship may include at least one of the following:

[0178] (1) The mapping relationship between the mapped Cell ID and the geographical area;

[0179] (2) the mapping relationship between TAC and geographical areas;

[0180] (3) The mapping relationship between TAI and geographical regions;

[0181] (4) The mapping relationship between CGI and geographical areas;

[0182] The mapping relationship may be pre-configured (eg, depending on the operator's policy) or may be configured based on implementation.

[0183] In one possible implementation, the method further includes:

[0184] (1) The core network device sends the terminal's location information to the access network device;

[0185] (2) The core network device receives the terminal's area information from the access network device.

[0186] The core network device sends the terminal's location information to the access network device, which determines the terminal's area information. The access network device then sends the terminal's area information to the core network device.

[0187] In a possible implementation, the core network device sends the location information of the terminal to the access network device, including:

[0188] (1) The core network device receives third information from the access network device, where the third information is used to indicate whether the access network device supports receiving or processing the terminal's location information;

[0189] (2) When the third information is used to indicate that the access network device supports receiving or processing the location information of the terminal, the core network device sends the location information of the terminal to the access network device.

[0190] The access network device can indicate to the core network device whether it supports receiving or processing the terminal's location information. When the access network device supports receiving or processing the terminal's location information, the core network device sends the terminal's location information to the access network device.

[0191] In one possible implementation, the method further includes:

[0192] When the core network device receives the second indication information from the terminal, or the third information is used to indicate that the access network device does not support receiving or processing the location information of the terminal, the core network device performs at least one of the following:

[0193] (1) Obtain the terminal's location information through the terminal's NAS process or the terminal's positioning process.

[0194] (2) Rejecting the NAS request process of the terminal, which may specifically include rejecting the terminal's registration request, attach request, PDN establishment request, PDU session establishment request, service request, etc.

[0195] (3) De-attach terminal;

[0196] (4) Go to the registration terminal;

[0197] In the case where the aforementioned terminal does not report location information to the core network device or the access network device does not support receiving or processing the terminal's location information, that is, when the core network cannot obtain the terminal location information in the manner described above, the core network device executes the terminal positioning process to obtain the UE location information, or the core network device continues to execute the subsequent NAS process, waits for the subsequent AS layer to establish security, and then obtains the UE's location information through RAN.

[0198] In one possible implementation, the method further includes:

[0199] (1) When it is determined based on the terminal's area information that the current area where the terminal is located does not allow communication on the current Public Land Mobile Network (PLMN), the core network device executes the NAS request rejection and release process;

[0200] (2) When it is determined based on the area information of the terminal that the current area where the terminal is located allows communication in the current PLMN, the core network device executes the NAS request processing procedure.

[0201] The core network equipment performs the terminal location verification process and NAS processing operations after location verification based on the terminal area information obtained and in accordance with regulatory requirements.

[0202] Referring to FIG4 , an embodiment of the present application provides a location information processing method. The method is performed by an access network device, such as an eNB or gNB. The embodiment of the present application does not limit the type of access network device, including:

[0203] Step 401: The access network device receives the terminal's location information from the core network device;

[0204] Step 402: The access network device determines the terminal's area information based on the terminal's location information;

[0205] Step 403: The access network device sends the terminal's area information to the core network device.

[0206] The core network device sends the terminal's location information to the access network device, which determines the terminal's area information. The access network device then sends the terminal's area information to the core network device.

[0207] In a possible implementation, the access network device receives the location information of the terminal from the core network device, including:

[0208] (1) The access network device sends third information to the core network device, where the third information is used to indicate whether the access network device supports receiving or processing the terminal's location information;

[0209] (2) When the third information is used to indicate that the access network device supports receiving or processing the location information of the terminal, the access network device receives the location information of the terminal from the core network device.

[0210] The access network device can indicate to the core network device whether it supports receiving or processing the terminal's location information. When the access network device supports receiving or processing the terminal's location information, the core network device sends the terminal's location information to the access network device.

[0211] The technical solution of the present application is described below in conjunction with specific embodiments. It should be noted that in the following embodiments, the access network device is eNB / gNB and the core network device is MME / AMF as an example.

[0212] Embodiment 1: The UE performs UE location reporting according to the first information;

[0213] Referring to FIG5a , in one embodiment, the first information is location reporting indication information sent by the core network:

[0214] 1. The UE sends an attach request or registration request to the MME / AMF.

[0215] 2. The MME / AMF carries first information in the Attach Accept or Registration Accept message, where the first information instructs the UE to report UE location information. The first information may also indicate the accuracy of the UE location information reported by the UE, such as coarse granularity or fine granularity. The UE location information includes at least one of the following types:

[0216] GNSS position, such as longitude and latitude;

[0217] GNSS position of specified accuracy, such as imprecise latitude and longitude;

[0218] Address information (such as a certain street, a certain building, a certain square, etc.);

[0219] Other information that can express the geographical location of the UE;

[0220] The first information also includes an instruction for the UE to carry the UE location information in subsequent NAS messages.

[0221] 3. The UE receives the registration accept / attach accept message, and sends the UE location information to the MME and AMF according to the instruction of the UE to report the UE location information in the first information. The specific information of the UE location information can also be determined according to the accuracy indication of the first information.

[0222] Referring to FIG. 5 b , one implementation manner is that after the UE obtains the first information sent by the network, the UE carries the UE location information in a subsequent NAS message.

[0223] One implementation method is that the UE sends the UE location information to the MME / AMF based on the first information received in the early stage during the subsequent service request process.

[0224] 1-3 are the same as Figure 5a;

[0225] 4-5: UE enters connected state from idle state;

[0226] 6: The UE carries the UE location information in the service request message according to the first information of the network (instructing the UE to report the UE location information).

[0227] Referring to Figure 5c, in one implementation mode, the first information is the NAS location reporting capability of the UE and / or the type of the UE includes NB-IOT device, eMTC device, etc. This method does not depend on whether the UE has received the UE location reporting instruction from the network. As long as the UE belongs to a type such as NB-IOT device, eMTC device, or the UE has the capability of performing UE location reporting through NAS messages, it reports its own location information through NAS messages.

[0228] One implementation method is that the UE carries the UE location information to the MME / AMF in the UE attach or registration complete message when registering.

[0229] As shown in Figure 5c, the UE determines that it has NAS location reporting capability or is a UE of the type NB-IOT device. The UE reports the UE location information to the core network (MME, AMF). One implementation method is that the UE carries the UE location information to the MME / AMF in an attach or registration complete message. The UE location information includes:

[0230] GNSS location information;

[0231] Address information;

[0232] Other information that can represent the UE location.

[0233] Referring to FIG. 5 d , another implementation manner is that the UE carries the UE location information in the service request message.

[0234] When the UE enters the connected state from the idle state, the UE carries the UE location information in the service request message.

[0235] The UE location information includes:

[0236] GNSS location information;

[0237] Address information;

[0238] Other information that can represent the UE location.

[0239] Embodiment 2: The core network sends the first information based on the NAS location reporting capability of the UE.

[0240] See Figure 5e:

[0241] 1. The UE carries information about its capability to report its location via NAS in the registration / attach request.

[0242] 2. The MME / AMF determines to send the first information (same as in Example 1, including:

[0243] a) The UE supports the capability of NAS to report the UE location, and the MME / AMF sends the first information to the UE.

[0244] b) The UE does not support the NAS capability of reporting the UE location, the MME / AMF does not send the first information to the UE, the AMF / MME executes the positioning process including the UE to obtain the UE location information, or the AMF / MME continues to execute subsequent NAS processes and waits for the subsequent AS layer to establish security before obtaining the UE location information through the RAN.

[0245] 3. The UE sends the UE location information to the MME / AMF.

[0246] Example 3: Core network processing of UE location

[0247] In one implementation, the core network determines the area information of the UE based on the UE location information and the first mapping relationship, where the area information of the terminal includes:

[0248] The TAC / TAI where the terminal is located;

[0249] The mapped Cell ID where the terminal is located, that is, the Cell ID corresponding to the fixed ground area;

[0250] The CGI described in the terminal.

[0251] The first mapping relationship includes at least one of the following:

[0252] The mapping relationship between the mapped Cell ID and the geographical area;

[0253] The mapping relationship between TAC and geographical areas;

[0254] The mapping relationship between TAI and geographical areas;

[0255] The mapping relationship between CGI and geographical areas;

[0256] The first mapping relationship may be pre-configured (eg, depending on an operator's policy) or may be configured based on implementation.

[0257] Referring to Figure 5f, one implementation method is that if the MME / AMF does not configure the UE location information and the first mapping relationship, the second UE location information is sent to the RAN (eNB / gNB) through the S1 / N2 message to request the RAN to return the UE area information. The RAN determines the UE area information based on the second UE location information, and the RAN returns the UE area information.

[0258] 1. The MME / AMF sends the second UE location information via an S1 / N2 message to request the RAN to return the UE area information. The second UE location information is determined based on the UE location information reported by the UE, including at least one of the following:

[0259] a) GNSS location information;

[0260] b) Address information;

[0261] c) Other information that can represent the UE location.

[0262] 2. The RAN receives the second UE location information and sends the UE area information to the MME and AMF. The UE area information includes at least one of the following:

[0263] a) TAC / TAI where the terminal is located;

[0264] b) The mapped Cell ID where the terminal is located, that is, the Cell ID corresponding to the fixed ground area;

[0265] c) CGI described by the terminal.

[0266] Referring to Figure 5g, another implementation is that the MME / AMF sends the second UE location information to the RAN based on the indication that the RAN is capable of receiving and / or processing the UE location information.

[0267] 1. The RAN sends indication information, where the indication information is used to indicate the capability of the RAN to receive and / or process the UE location information. The indication information may be carried in the NG setup request.

[0268] 2. Based on the RAN's ability to receive and / or process the UE location information, the MME / AMF sends the second UE location information to the RAN to request the UE's area information.

[0269] a) The RAN supports receiving and / or processing the UE location information, and the MME / AMF sends the second UE location information to the RAN;

[0270] b) The RAN does not support receiving and / or processing the UE location information, the MME / AMF does not send the second UE location information to the RAN, and the AMF / MME further performs a positioning procedure for the UE to obtain the UE location information, or the AMF / MME continues to perform subsequent NAS procedures and waits for the subsequent AS layer to establish security before obtaining the UE location information through the RAN;

[0271] 3. The RAN generates the UE area information based on the second UE location information and sends the area information to the AMF / MME.

[0272] Example 4: Operations after the core network obtains the UE's area information;

[0273] The MME / AMF obtains the UE's area information according to the second and third embodiments and performs the UE's location verification process and post-location verification NAS processing operations according to regulatory requirements, including:

[0274] The UE's current location does not allow communication in the current PLMN, and the NAS request rejection and release process is performed;

[0275] The UE's current location area allows it to communicate in the current PLMN and execute subsequent NAS requests.

[0276] Embodiment 5: The UE further determines whether to report the UE location information based on the second information and notifies the network side.

[0277] See Figure 5h:

[0278] Steps 1-2 are the same as in Example 1;

[0279] Step 3: The UE further determines to report the UE location information based on the second information, where the second information includes at least one of the following:

[0280] Whether the UE user agrees to report the UE location information;

[0281] Whether the UE's current location information is available or valid.

[0282] One implementation manner is to report the UE location information when the UE user agrees to report the UE location information, and send the UE location information in step 4.

[0283] One implementation manner is that the current location information of the UE is valid or available, the location information of the UE is reported, and the location information of the UE is sent in step 4.

[0284] In one embodiment, if the UE user does not agree to report the UE location information, or the current location information of the UE is unavailable or invalid, the UE location information and / or the UE location non-reporting indication information are not sent in step 4, and the reason for not neglecting the UE location is also included, including at least one of the following:

[0285] For example, due to UE privacy issues, the UE location is not available.

[0286] After step 4, the MME / AMF receives the UE location not reported information from the UE, and the MME / AMF performs the following operations:

[0287] Continue to execute the subsequent NAS process;

[0288] Initiate the UE positioning process.
