[0004] In non-terrestrial networks (NTNs), the network can perform mobility management for terminals after obtaining their location information, including determining whether to allow services to the terminal. However, the transmission of location information between user equipment (UE) and the network via Radio Resource Control (RRC) signaling requires access stratum (AS) security. For narrowband IoT devices with support for CP CIoT EPS Optimization only (NB-IoT devices), AS connections are not secure in satellite access scenarios. To protect user privacy, location information must be encrypted before being sent to the network. However, the current mechanism for terminals to report location information (here, tracking area identity (TAI)) is not applicable to NTN IoT UEs.

[0097] The following first describes the technologies related to the embodiments of the present application.

[0098] 1. Non-Terrestrial Networks (NTN) access

[0099] Non-terrestrial networks refer to networks or network terminals that use satellites or unmanned aerial vehicle systems for communication transmission. These networks cover typical communication scenarios and situations where ground base stations are unavailable or temporarily damaged, such as remote areas, deserts, coastal areas, primeval forests, and areas susceptible to fires and earthquakes. Satellite communications include Low Earth Orbiting (LEO), Medium Earth Orbiting (MEO), Geostationary Earth Orbiting (GEO), and Highly Elliptical Orbiting (HEO).

[0100] Typical scenarios of non-terrestrial networks include transparent forwarding, where the satellite acts as a forwarding relay, 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.

[0101] 2. Location verification

[0102] For conventional terminals (eMTC UE) accessing terrestrial networks (TN), after the terminal decides to access a cell during the access process of the access stratum (AS), the base station will learn the UE's resident cell information through AS signaling. In TN access, a cell corresponds one-to-one to a tracking area (TA). A cell ID uniquely corresponds to a tracking area identity (TAI, which is composed of a public land mobile network identity (PLMN ID) and a tracking area code (TAC)). In this way, the base station side can determine the current location information of the UE. The location information includes the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) global cell identity, TAI, primary serving cell (PCell), primary secondary cell (PScell) information, long-term evolution non-terrestrial network tracking area identity information (LTE NTN TAI information), serving public land mobile network (serving PLMN), TAC and other information. These location information can be collectively referred to as user location information (ULI). However, in NTN access, the relationship between cells and TAs is not fixed. One cell may correspond to multiple TAs. Therefore, it is necessary to determine which TAI the UE is in based on its actual location.

[0103] After the UE determines its Global Navigation Satellite System (GNSS) location, is it feasible to let the UE determine its TAI? The answer is no, because for devices like NTN IoT, storing a large number of location and TA mappings would consume additional power. Currently, this mapping information (including the mapping relationship between GNSS location and TAI, and the mapping relationship between cell and TAI, etc.) is stored on the network side, so the network needs to determine the UE's TAI.

[0104] In the above scenario, the UE can obtain its own GNSS position through the GNSS module, but it is unknown how the network side can obtain the UE's ULI information without the security of the AS.

[0105] The information processing method, apparatus, and communication device provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0106] As shown in FIG2 , an embodiment of the present application provides an information processing method, including:

[0107] Step 201: A first core network device receives target location information sent by a terminal;

[0108] It should be noted that the target location information mentioned in the embodiments of the present application can be understood as the geographical location information obtained by the terminal through positioning. In some embodiments, the geographical location information can be the GNSS location information obtained by the terminal through GNSS positioning.

[0109] In some embodiments, the target location information may include at least one of the following:

[0110] A11, the latitude and longitude coordinate information of the geographical location of the terminal;

[0111] A12. Coarsening the latitude and longitude coordinate information of the terminal's geographical location;

[0112] The positioning accuracy of the latitude and longitude coordinate information of the terminal's geographical location is higher than that of the latitude and longitude coordinate information of the terminal's geographical location after fuzzy processing.

[0113] It should be noted here that the target location information can be the longitude and latitude coordinate information directly obtained by the terminal through a specific positioning method; of course, in order to further avoid the exposure of the specific location of the terminal, the target location information can also be the longitude and latitude coordinate information after fuzzification. It should be noted that the positioning accuracy of the longitude and latitude coordinate information will decrease after fuzzification, and its granularity can be between the longitude and latitude coordinates and the cell / tracking area (TA).

[0114] Step 202: The first core network device performs a target operation based on the target location information;

[0115] In some embodiments, the target operation includes at least one of the following:

[0116] A21. Obtain user location information mapped to the target location information;

[0117] It should be noted that this situation refers to the first core network device mapping the target location information to the user location information, and obtaining the user location information (ULI) corresponding to the target location information;

[0118] It should be noted that, in this case, the first core network device is configured with a mapping relationship between the target location information and the user location information, and the first core network device can directly determine the user location information corresponding to the target location information based on the mapping relationship.

[0119] A22. Send the target location information to the second core network device;

[0120] It should be noted that in this case, it can be understood that the mapping relationship between target location information and user location information is not configured in the first core network device, and the second core network device needs to obtain user location information based on the target location information.

[0121] A23. Send the target location information to a target device, where the target device is an access network device or a mapping server;

[0122] It should be noted that in this case, it can be understood that the mapping relationship between the target location information and the user location information is not configured in the first core network device. The mapping relationship is configured in the target device, and the target device needs to obtain the user location information based on the target location information.

[0123] It should be noted that the embodiment of the present application maps the target location information to the user location information by receiving the target location information sent by the terminal, and obtains the user location information corresponding to the target location information, or sends the target location information to the second core network device, and the second core network device obtains the user location information, or sends the target location information to the target device, and the target device obtains the user location information, thereby realizing the acquisition of user location information of terminals without AS security, and then performing access management and mobility management of such terminals.

[0124] In some embodiments, the first core network device mentioned in the embodiments of the present application refers to a device capable of performing positioning management, for example, the first core network device can be an evolved service mobile positioning center (E-SMLC) or a positioning management network element (Location Management Function, LMF); the second core network device refers to a device capable of performing mobility and access management, for example, the second core network device can be an MME or an AMF, etc.

[0125] The following are detailed descriptions of different target operations.

[0126] 1. Target operations include A21

[0127] It should be noted that, in this case, the first core network device itself maps the user location information. In some embodiments, after the first core network device maps and obtains the user location information, in one implementation, the method further includes at least one of the following:

[0128] A121. The first core network device sends the user location information to the second core network device.

[0129] It should be noted that, by sending the user location information to the second core network device, the second core network device can perform access management and mobility management based on the user location information.

[0130] A122. The first core network device sends the user location information to the target device;

[0131] It should be noted that, in this case, the target device usually refers to an access network device. By sending the user location information to the target device, the target device can be assisted in configuring the terminal transmission parameters to ensure the communication reliability of the terminal.

[0132] 2. Target operations include A22

[0133] It should be noted that, in this case, the second core network device needs to obtain the user location information based on the target location information.

[0134] In some embodiments, the second core network device may obtain the user location information in one of the following ways:

[0135] A221. The second core network device maps the target location information to the user location information, and obtains the user location information corresponding to the target location information.

[0136] It should be noted that, in this case, the second core network device is configured with a mapping relationship between the target location information and the user location information, and the second core network device can directly determine the user location information corresponding to the target location information based on the mapping relationship.

[0137] In some embodiments, in this case, in one implementation, the method further includes:

[0138] The second core network device sends user location information corresponding to the target location information to the target device;

[0139] It should be noted that, in this case, the target device usually refers to an access network device. By sending the user location information to the target device, the target device can be assisted in configuring the terminal transmission parameters to ensure the communication reliability of the terminal.

[0140] A222. The second core network device sends target location information to the target device, and the second core network device receives user location information corresponding to the target location information sent by the target device.

[0141] It should be noted that in this case, it can be understood that the mapping relationship between the target location information and the user location information is not configured in the second core network device. The mapping relationship is configured in the target device, and the target device needs to obtain the user location information based on the target location information and feed it back to the second core network device.

[0142] In some embodiments, in this case, after receiving the target location information, the target device maps the target location information to the user location information based on the target location information, obtains the user location information corresponding to the target location information, and sends the user location information to the second core network device.

[0143] 3. Target operations include A23

[0144] It should be noted that, in this case, the target device needs to obtain the user location information based on the target location information.

[0145] In some embodiments, in one implementation, the specific implementation of sending the target location information to the target device includes:

[0146] The first core network device sends a target message to the target device;

[0147] Wherein, the target message includes target location information; or,

[0148] The target message includes target location information and target indication information, and the target indication information is used to request user location information mapped by the target location information.

[0149] In some embodiments, when the target device obtains the target indication information, it determines that it is necessary to map the target location information to obtain the user location information; in some embodiments, when the target device obtains the target indication information, it determines that it is necessary to map the target location information to obtain the user location information, and replies to the user location information to the first core network device.

[0150] In some embodiments, the target message may be a newly introduced message for indicating the location mapping of the target location information. In this case, the target message may only include the target location information. In some embodiments, the target message may also be a reused existing message. In this case, the target message needs to include target location information and target indication information, so that the target device clearly knows which subsequent actions need to be performed after receiving the target message.

[0151] In some embodiments, after receiving the target location information, the target device maps the target location information to the user location information based on the target location information, obtains the user location information corresponding to the target location information, and sends the user location information, i.e., ULI information, to the first core network device or the second core network device.

[0152] It should be noted here that, in one case, if the target device sends the user location information to the first core network device, then in one implementation, the method further includes:

[0153] The first core network device receives user location information corresponding to the target location information sent by the target device.

[0154] Furthermore, after the first core network device obtains the user location information, in some embodiments, in one implementation, the method further includes:

[0155] The first core network device sends the user location information to the second core network device.

[0156] It should be noted that, by sending the user location information to the second core network device, the second core network device can perform access management and mobility management based on the user location information.

[0157] It should be noted here that, in another case, if the target device sends the user location information to the second core network device, then in one implementation, the method further includes:

[0158] The target device sends confirmation information to the first core network device, where the confirmation information is used to indicate that the user location information corresponding to the target location information has been sent to the second core network device.

[0159] It can be understood here that since the user location information is used by the second core network device, that is, in this case, the user location information is directly fed back to the second core network device, and the target device only needs to notify the first core network device that it has completed the relevant operations, so that the first core network device is clearly aware of the subsequent execution process. This method can reduce signaling overhead.

[0160] The following is a detailed description of the reporting of target location information.

[0161] In some embodiments, the terminal sends the target location information to the first core network device according to the second condition;

[0162] The second condition includes at least one of the following:

[0163] B11. The terminal receives first information sent by a first core network device, where the first information is used to instruct the terminal to report target location information;

[0164] This method can be understood as the terminal sending the target location information based on the request of the first core network device.

[0165] In some embodiments, the first information includes at least one of the following:

[0166] B111. Position accuracy, where the position accuracy indicates the positioning accuracy of the target position information reported by the terminal.

[0167] B112, first indication information, the first indication information is used to instruct the terminal to report target location information;

[0168] B113, second indication information, the second indication information is used to indicate the positioning method used by the terminal to obtain target location information;

[0169] In some embodiments, the positioning method includes but is not limited to: GNSS positioning, Galileo satellite navigation positioning, Beidou positioning, etc.

[0170] B114, third indication information, the third indication information is used to indicate the message encapsulation method of the terminal reporting the target location information;

[0171] For example, the message encapsulation manner may include, but is not limited to: encapsulation through Long Term Evolution Positioning Protocol (LTE Positioning Protocol, LPP) message encapsulation and encapsulation through Non-Access Stratum (NAS) message encapsulation.

[0172] In some embodiments, in one implementation, the first core network device sends first information to the terminal under a first condition, where the first information is used to instruct the terminal to report target location information;

[0173] The first condition includes at least one of the following:

[0174] C11. Receive second information sent by a second core network device, where the second information is used to trigger the first core network device to obtain target location information of the terminal;

[0175] In some embodiments, the second information includes at least one of the following:

[0176] C111. Fourth indication information, where the fourth indication information is used to instruct the first core network device to obtain target location information of the terminal;

[0177] It should be noted that the fourth indication information can be an explicit indication or an implicit indication. In the implicit indication mode, the second information does not include the fourth indication information, that is, the second core network device can use a dedicated message to request the first core network device to obtain the target location information, that is, the type of information can implicitly instruct the first core network device to obtain the target location information of the terminal.

[0178] C112. Trigger type, where the trigger type is used to indicate a reason why the second core network device sends the second information;

[0179] In some embodiments, the trigger type may be a non-terrestrial network location verification (NTN location verification) or a network initiated location request (NI-LR).

[0180] C113, location accuracy, the location accuracy is used to indicate the positioning accuracy of the target location information reported by the terminal;

[0181] One implementation method is co-ordinate or coarse co-ordinate (coarse co-ordinate can be understood as a type of location information after fuzzification processing based on the satellite latitude and longitude coordinates obtained by the GNSS module. The granularity of this location is between the latitude and longitude coordinates and the cell / TA).

[0182] C114. A positioning method used to obtain target location information of the terminal;

[0183] One implementation is GNSS. If not provided, E-SMLC determines it after receipt.

[0184] C115. Requested location information, where the requested location information indicates a desired location description method for the terminal by the second core network device. The location description method may be understood as a description granularity or a representation granularity of the location.

[0185] In some embodiments, the location description method includes at least one of the following:

[0186] C1151, cell global identity (CGI);

[0187] In some embodiments, the cell global identifier may be, for example, an E-UTRAN CGI, an NR CGI, etc. The CGI may include an NTN CGI where the terminal is located, and a CGI where the terminal is mapped to the ground.

[0191] C1155, Serving Public Land Mobile Network (Serving PLMN);

[0192] C1156, Tracking Area Code (TAC).

[0193] C116, indication of whether satellite access is allowed;

[0194] It can be understood that the requested location information is used to indicate that the second core network device expects to use at least one of C1151-C1156 to describe the location of the terminal.

[0195] It should be noted that the indication of whether satellite access is allowed can be understood as being used to instruct the first core network device to determine whether the terminal is allowed to access satellite based on location information such as the terminal's country, TA, cell, or GNSS coordinates.

[0196] In some embodiments, the second information may be sent through an existing NI-LR location authentication link. For example, the second information is included in a location request message sent by the second core network device to the first core network device.

[0197] Alternatively, the second information may also be transmitted through a new NI-LR process, for example, through a newly added dedicated message, where the dedicated message is a message requesting a ULI.

[0198] C12. Determining that the terminal supports reporting target location information;

[0199] In some embodiments, the terminal supports reporting target location information in at least one of the following ways of understanding:

[0200] The terminal supports reporting target location information without access layer security;

[0201] The terminal supports reporting target location information via LPP;

[0202] The terminal supports reporting target location information through NAS messages.

[0203] In some embodiments, in one implementation of this situation, the method further includes:

[0204] The first core network device sends positioning capability query request information to the terminal;

[0205] The first core network device receives the positioning capability reply information sent by the terminal;

[0206] The positioning capability reply information includes the following:

[0207] fifth indication information, where the fifth indication information is used to indicate that the terminal supports reporting target location information;

[0208] sixth indication information, the sixth indication information being used to indicate that the terminal does not support reporting target location information;

[0209] In some embodiments, the terminal does not support reporting of target location information, which may include at least one of the following understandings:

[0210] The terminal does not support reporting target location information without access layer security;

[0211] The terminal does not support reporting target location information via LPP;

[0212] The terminal does not support reporting target location information through NAS messages.

[0213] It should be noted that if the positioning capability reply information received by the first core network device includes the fifth indication information, it means that the terminal is capable of providing the target location information for the first core network device, and the first core network device can then send the first information to the terminal to request the target location information. If the positioning capability reply information received by the first core network device includes the sixth indication information, it means that the terminal is unable to provide the target location information for the first core network device, and the first core network device cannot send the first information to the terminal.

[0214] It should also be noted here that if the terminal receives the first information from the first core network device, but the terminal determines that it cannot provide the target location information, in some embodiments, in one implementation, the method further includes:

[0215] The first core network device receives a first rejection message sent by the terminal, where the first rejection message is used to indicate that the terminal cannot provide target location information.

[0216] That is to say, when the terminal cannot provide the target location information, the terminal needs to send a rejection message to the first core network device to reject the request of the first core network device.

[0217] In some embodiments, in one implementation, the first rejection message includes a first cause value, where the first cause value is used to indicate a reason why the target location information of the terminal cannot be provided, including at least one of the following:

[0218] The terminal does not support reporting target location information;

[0219] The terminal refuses to report the target location information due to user privacy.

[0220] In some embodiments, one implementation method is that the first rejection message is carried in an attach request message (attach request message) or an attach complete message (attach complete message) or an attach reject message (attach reject message) or a registration request message (registration request message) or a registration complete message (registration complete message) or a registration reject message (registration reject message) or a tracking area update request message (tracking area update request message) or a security mode complete message (security mode complete message) or a security mode reject message (security mode reject message) or an uplink generic NAS transport message (uplink generic NAS transport message) or an uplink non-access layer transport message (uplink NAS Transport message). Specifically, the first rejection message can be encapsulated in a newly created information element (IE) or a payload container information element (payload container IE) (for example: LPP container).

[0221] In some embodiments, if the terminal sends a first rejection message to the first core network device, then when the first core network device receives the second information sent by the second core network device, the first core network device needs to reply to the second core network device with a second rejection message, where the second rejection message is used to indicate that the target location information of the terminal cannot be provided.

[0222] In some embodiments, in one implementation, if the first core network device receives the second information and the second information carries fourth indication information, the first core network device may reply a second rejection message to the second core network device.

[0223] In some embodiments, the second rejection message includes a second cause value, where the second cause value is used to indicate a reason why the target location information of the terminal cannot be provided, including at least one of the following:

[0224] The terminal does not support reporting target location information;

[0225] The terminal refuses to report the target location information due to user privacy.

[0226] B12. The terminal receives third information sent by the second core network device, where the third information is used to instruct the terminal to report target location information;

[0227] This method can be understood as the terminal sending the target location information based on the request of the second core network device.

[0228] In some embodiments, the third information includes at least one of the following:

[0229] B121, location accuracy, where the location accuracy indicates the location accuracy of the target location information reported by the terminal;

[0230] B122, seventh indication information, the seventh indication information is used to instruct the terminal to report target position information with target accuracy;

[0231] B123, eighth indication information, the eighth indication information is used to indicate the positioning method adopted by the terminal to obtain target position information with target accuracy;

[0232] In some embodiments, the positioning method includes but is not limited to: GNSS positioning, Galileo satellite navigation positioning, Beidou positioning, etc.

[0233] B124, ninth indication information, the ninth indication information is used to indicate a message encapsulation method for the terminal to report target location information;

[0234] For example, the message encapsulation manner may include, but is not limited to: encapsulation through a Long Term Evolution Positioning Protocol (LTE Positioning Protocol, LPP) message, and encapsulation with a Non-Access Stratum (NAS) message.

[0235] In some embodiments, in one implementation, the second core network device needs to receive capability information sent by the terminal, where the capability information is used to indicate whether the terminal supports reporting target location information. The second core network device can only send the third information to the terminal if it determines that the terminal supports reporting target location information.

[0236] In some embodiments, if the terminal receives the third information sent by the second core network device, but the terminal is unable to provide the target location information, in one implementation method, the second core network device receives the third rejection message sent by the terminal, and the third rejection message is used to indicate that the terminal is unable to provide the target location information.

[0237] In one implementation, the third rejection message is carried in an attach request message, an attach complete message, a tracking area update request message, an uplink generic NAS transport message, or an uplink NAS Transport message and is sent to the second core network device.

[0238] In one implementation, the third rejection message is carried in a registration request message, a registration complete message, a registration reject message, a UL NAS TRANSPORT message, a security mode complete message, or a security mode reject message and is sent to the second core network device.

[0239] That is to say, when the terminal cannot provide the target location information, the terminal needs to send a rejection message to the second core network device to reject the request of the second core network device.

[0240] In some embodiments, the third rejection message includes a third cause value, where the third cause value is used to indicate a reason why the target location information of the terminal cannot be provided, including at least one of the following:

[0241] The terminal does not support reporting target location information;

[0242] The terminal refuses to report the target location information due to user privacy.

[0243] B13. The terminal decides to report the target location information;

[0244] It should be noted that in this case, it can be understood that the terminal decides to report the target location information to the network, that is, the terminal proactively reports the target location information to the network. For example, one implementation method is: the terminal triggers the reporting of target location information due to satellite access, and the accuracy is the default accuracy (such as coordination); another implementation method is: the terminal is stationed in an NTN cell and the terminal must report the target location information, and the accuracy is the default accuracy.

[0245] In summary, the situations in which the terminal reports the target location information can be summarized as follows:

[0246] Case 1: The second core network device sends second information to the first core network device, the first core network device sends first information to the terminal according to the second information, and the terminal feeds back target location information according to the first information.

[0247] Case 2: The second core network device sends third information to the terminal, and the terminal feeds back target location information based on the third information.

[0248] Case 3: The first core network device sends a positioning capability query request message to the terminal; the terminal feeds back positioning capability reply message based on the positioning capability query request message; the first core network device sends first information to the terminal based on the positioning capability reply message, and the terminal feeds back target location information based on the first information.

[0249] Case 4: The terminal sends capability information to the second core network device, the second core network device sends third information to the terminal according to the capability information, and the terminal feeds back target location information according to the third information.

[0250] Case 5: The terminal sends capability information to the second core network device, the second core network device sends second information to the first core network device based on the capability information, the first core network device sends first information to the terminal based on the second information, and the terminal feeds back target location information based on the first information.

[0251] Case 6: The terminal locally decides to send the target location information.

[0252] In some embodiments, in one implementation, the user location information in the embodiments of the present application includes at least one of the following:

[0253] D11, community global identification;

[0254] D12, tracking area identification;

[0255] D13, primary service cell information;

[0256] D14, primary and secondary cell information;

[0257] D15, serving the public land mobile network;

[0258] D16, tracking area code.

[0259] The following takes the first core network device as E-SMLC, the second core network device as MME, the target device as access network device, and the terminal reporting GNSS location information as an example to illustrate the specific implementation of this application as follows.

[0260] Application Scenario 1: E-SMLC and RAN Interact to Obtain ULI

[0261] As shown in Figure 3, the main implementation process includes:

[0262] Step 31: The network triggers or the terminal locally decides to perform GNSS position information reporting;

[0263] There are mainly the following implementation methods, and you can choose one based on your needs:

[0264] Method 1:

[0265] Step 31a-1: The MME sends second information to the E-SMLC, where the second information is used to trigger the E-SMLC to obtain the GNSS location information of the terminal;

[0266] In some embodiments, the second information may be sent via a first trigger message, where the first trigger message is used to trigger the E-SMLC to collect the location of the terminal for location confirmation, and the message carries:

[0267] Association ID, used to uniquely identify a location confirmation session;

[0268] Second information.

[0269] In some embodiments, the second information includes at least one of the following:

[0270] Fourth indication information, where the fourth indication information is used to instruct the first core network device to obtain GNSS location information of the terminal;

[0271] a trigger type, where the trigger type is used to indicate a reason why the second core network device sends the second information;

[0272] Position accuracy, where the position accuracy indicates the positioning accuracy of the target position information reported by the terminal;

[0273] The positioning method used to obtain the GNSS position information of the terminal;

[0274] Requested location information, where the requested location information indicates a location description method of the terminal desired by the second core network device;

[0275] An indication of whether satellite access is allowed.

[0276] In one implementation manner, the first trigger message is carried in a Location Request message from the MME to the E-SMLC.

[0277] It should be noted that the content in the requested location information may be a default configuration, such as including all the above-mentioned ULI information, or including content excluding the result indication of whether satellite access is allowed.

[0278] Step 31a-2: After receiving the second information from the MME, the E-SMLC determines a positioning method (such as GNSS positioning), and sends a first message to the terminal, where the first message is used to instruct the terminal to report GNSS location information.

[0279] In some embodiments, the first information may be sent via a first message, where the first message includes:

[0280] Association ID;

[0281] First information.

[0282] In some embodiments, the first information includes at least one of the following:

[0283] Position accuracy, where the position accuracy indicates the positioning accuracy of the GNSS position information reported by the terminal;

[0284] first indication information, where the first indication information is used to instruct the terminal to report GNSS location information;

[0285] Second indication information, where the second indication information is used to indicate a positioning method used by the terminal to obtain GNSS position information;

[0286] The third indication information is used to indicate a message encapsulation method for the terminal to report GNSS location information.

[0287] It should be noted that one implementation method is that the E-SMLC transmits the first information to the terminal through an LPP message. The message is sent by the E-SMLC to the MME and then forwarded to the UE. The message is carried in the container of N1.

[0288] After the terminal receives the first information, in one implementation, the terminal obtains GNSS location information through a GNSS positioning method (for example, through a GNSS module).

[0289] Method 2:

[0290] Step 31b: The MME sends third information to the terminal;

[0291] The third information may be sent via a second message, and the second message may carry:

[0292] Association ID;

[0293] Third information.

[0294] In some embodiments, the third information includes at least one of the following:

[0295] Position accuracy, where the position accuracy indicates the positioning accuracy of the GNSS position information reported by the terminal;

[0296] Seventh indication information, the seventh indication information is used to instruct the terminal to report GNSS position information of target accuracy;

[0297] Eighth indication information, where the eighth indication information is used to indicate a positioning method used by the terminal to obtain GNSS position information of a target accuracy;

[0298] Ninth indication information, the ninth indication information is used to indicate a message encapsulation method for the terminal to report GNSS location information.

[0299] It should be noted that after receiving the second message, the terminal obtains GNSS location information through a GNSS positioning method.

[0300] In one implementation, the second information is carried in an attach accept message, a tracking area update accept message, a downlink generic NAS transport message, or a downlink NAS transport message and sent to the terminal.

[0301] Method 3:

[0302] Step 31c: The terminal decides to report the GNSS location information to the network.

[0303] One implementation method is: the terminal triggers GNSS position information reporting due to satellite access, and the accuracy is the default accuracy (such as coordination); the terminal resides in the NTN cell, and the terminal must report GNSS position information with the default accuracy.

[0304] Method 4:

[0305] Step 31d-1: The E-SMLC sends a positioning capability query request message to the terminal to obtain the positioning capability of the terminal.

[0306] One implementation method is to use the LPP capability transfer procedure, that is, the E-SMLC sends a RequestCapabilities message to the terminal.

[0307] In one implementation, this step is optional, that is, this step does not occur, the terminal directly performs step 1d-2, and the E-SMLC performs step 1d-3.

[0308] Step 31d-2: The terminal sends a positioning capability reply message to the E-SMLC, providing its own positioning capabilities. The positioning capability reply message includes:

[0309] Fifth indication information, the fifth indication information is used to indicate that the terminal supports reporting GNSS position information.

[0310] One implementation method is to use the LPP capability transfer procedure, that is, the terminal sends a ProvideCapabilities message.

[0311] Step 31d-3: The E-SMLC sends the first information to the terminal according to the capability of step 31d-3 and supports reporting of GNSS location information.

[0312] The rest of this step is the same as step 31a-2 and will not be described again here.

[0313] Method 5:

[0314] Step 31e-1: The terminal sends capability information to the MME, where the capability information is used to indicate whether the terminal supports reporting GNSS location information.

[0315] In one implementation, the capability information is carried in an attach request message, an attach complete message, a tracking area update request message, an uplink generic NAS transport message, or an uplink NAS transport message and sent to the MME.

[0316] It should be noted that after receiving the terminal's capability information, the MME, in some embodiments, carries the terminal's capability information to the E-SMLC in step 3a-1, informing the E-SMLC of the terminal's capability, so that the E-SMLC can choose whether to execute step 3a-2 according to the terminal's capability when executing step 3a-1. In one implementation, when step 3a-1 does not carry the terminal's capability information, and the capability information indicates that the terminal supports reporting location information without AS security or reporting GNSS position via LPP, the E-SMLC may send the first information to the terminal.

[0317] Step 31e-2: The MME sends the third information to the terminal based on the capability information of the terminal. If the capability information of the terminal supports reporting the GNSS location information, the MME sends the third information to the terminal.

[0318] The rest of this step is the same as step 3b and will not be repeated here.

[0319] Step 32: The terminal sends GNSS location information to the E-SMLC.

[0320] In some embodiments, the GNSS location information may be carried in a third message, wherein the third message carries the GNSS location information. Further, the third message may also carry at least one of the following:

[0321] Association ID;

[0322] The terminal supports the ability to report GNSS location information;

[0323] The location information needs to be mapped to the access network and obtain the ULI indication for location verification under NTN access;

[0324] Access network device identification, which represents the identification information of the access network device currently in service, such as device ID;

[0325] GNSS accuracy information indicates the accuracy of GNSS position information, such as coordination or coarse coordination.

[0326] One implementation method is to carry the GNSS location information in an attach request message or an attach complete message or a tracking area update request message or a security mode complete message or an uplink generic NAS transport message or an uplink NAS Transport message. Specifically, the GNSS location information can be encapsulated in a newly created IE or a payload container IE (for example, an LPP container). And an indication information can be included in the access request message to indicate that the newly created IE or payload container carries the GNSS location for NTN location verification. After receiving the message, the MME sends the message and the indication information to the E-SMLC. After receiving the information forwarded by the MME, the E-SMLC performs subsequent steps.

[0327] Step 33: After receiving the GNSS location information, the E-SMLC sends the GNSS location information to the service access network device or mapping server of the terminal;

[0328] In some embodiments, the GNSS location information may be sent via a target message, wherein the target message carries the GNSS location information; further, the target message may also carry at least one of the following:

[0329] Association ID;

[0330] Target indication information, where the target indication information is used to request user location information mapped to the target location information.

[0331] It should be noted that the mapping server stores the capability to support location mapping on a core network element or network server. The E-SMLC queries the network element or server for this capability, obtains the address of the mapping server, and sends the target message to the corresponding mapping server to request GNSS location mapping. The mapping server here is a dedicated server (including a base station or network element), not a specific base station.

[0332] It should be noted that, when E-SMLC learns the serving base station of the terminal, it can determine the serving base station of the terminal based on the GNSS position reported by the terminal and send a target message to it; or E-SMLC determines the serving base station based on the base station identification information carried in the third message.

[0333] In one implementation, the target message is encapsulated in an S1-AP Transport message and sent to the MME. The MME then forwards it to the base station. The target message can be a Long Term Evolution Positioning Protocol A (LPPa) message.

[0334] Step 34: The access network device or the mapping server maps the received GNSS location information and outputs a ULI.

[0335] Step 35: The access network device or mapping server sends the ULI;

[0336] In some embodiments, after the access network device or mapping server completes GNSS mapping, there are two implementation methods:

[0337] Implementation 35a: The access network device or mapping server sends the mapped ULI to the E-SMLC, which then sends it to the MME.

[0338] Specifically include:

[0339] Step 35a-1: The access network device or mapping server sends the mapped ULI to the E-SMLC.

[0340] In some embodiments, the ULI may be sent via a fifth message.

[0341] In some embodiments, the fifth message may be sent via LPPa signaling.

[0342] In addition to the ULI, the fifth message may also include: a correlation ID.

[0343] In one implementation, the fifth message is encapsulated in an S1-AP Transport message and sent to the MME, which then forwards it to the E-SMLC. The fifth message may be an LPPa message.

[0344] Step 35a-2: The E-SMLC sends the mapped ULI to the MME for location confirmation. The E-SMLC sends a sixth message to the MME, where the sixth message carries:

[0345] Association ID;

[0346] ULI;

[0347] The result indicates whether the terminal is allowed to access the NTN network, including one of the following: allow or deny.

[0348] One implementation method is that when the MME carries a "result indication of whether satellite access is allowed" in the request of step 3a-1, the E-SMLC locally confirms whether the ULI (for example, TAI, cell ID) where the UE is located can support the access of the terminal, and returns a result indication to the MME: allow, reject; to indicate that the terminal is allowed to be accessed or rejected to access the NTN.

[0349] In one implementation, the sixth message is carried in a Location Response message from the E-SMLC to the MME.

[0350] Implementation 35b: The access network device or mapping server sends the mapped ULI directly to the MME and optionally informs the E-SMLC that it has received the GNSS location information.

[0351] Specifically include:

[0352] Step 35b-1: The access network device or mapping server sends the mapped ULI to the MME.

[0353] In some embodiments, the access network device or the mapping server sends a seventh message to the MME, where the seventh message carries:

[0354] Association ID;

[0355] ULI.

[0356] One implementation method is that in step 33, when the E-SMLC carries target indication information in the target message, the target message may optionally carry MME identification information, such as GUMMEI; another implementation method is that the access network device or mapping server understands the target indication information used to indicate location mapping of the GNSS location information, and replies to the ULI as: after executing the GNSS, the ULI information is sent to the MME by default. Therefore, after the access network device or mapping server completes the mapping of the GNSS location information, the ULI information is sent to the MME. In addition, the target message may optionally carry MME identification information, such as GUMMEI.

[0357] In one implementation, the seventh message is encapsulated in an S1-AP Transport message and sent to the MME.

[0358] Step 35b-2: The access network device or the mapping server sends a confirmation message to the E-SMLC, where the confirmation message indicates that the user location information corresponding to the GNSS location information has been sent to the second core network device.

[0359] It should be noted that this step is optional.

[0360] In some embodiments, the confirmation information may be sent via an eighth message, confirming that the GNSS location information in step 33 has been received. The eighth message may optionally carry an indication informing the E-SMLC that the ULI information of the UE has been sent to the MME.

[0361] In one implementation, the eighth message is encapsulated in an S1-AP Transport message and sent to the MME, which then forwards it to the E-SMLC. The eighth message may be an LPPa message.

[0362] Application Scenario 2: MME and RAN Interact to Obtain ULI

[0363] As shown in Figure 4, the main implementation process includes:

[0364] Step 41, see step 31 of application scenario 1;

[0365] Step 42, see step 32 of application scenario 1;

[0366] Step 43: After receiving the GNSS location information, the E-SMLC sends the GNSS location information to the MME.

[0367] Step 44: The MME obtains the ULI corresponding to the GNSS location information.

[0368] This step can be implemented in one of the following two ways:

[0369] Method 1:

[0370] Specifically include:

[0371] Step 44a: The MME maps the GNSS location information to the user location information, and obtains the ULI corresponding to the GNSS location information.

[0372] That is, in this implementation, the MME locally learns or stores the mapping relationship between the GNSS position and the ULI, and performs the mapping locally. The mapping relationship is configured in the MME.

[0373] Method 2:

[0374] Specifically include:

[0375] Step 44b-1: The MME sends the GNSS location information to the service access network device or mapping server of the terminal;

[0376] In some embodiments, the GNSS location information may be sent via a ninth message, which may additionally carry location mapping of the GNSS location information and reply to an indication of the ULI; an optional implementation method is: the MME sends an S1-AP Transport message.

[0377] Step 44b-2: After the mapping is completed, the access network device or mapping server sends the ULI to the MME.

[0378] In some embodiments, the ULI may be sent via a tenth message, which carries the ULI. An optional implementation manner is: the access network device or the mapping server sends an S1-AP Transport message.

[0379] Application Scenario 3: E-SMLC locally maps GNSS location information to ULI

[0380] As shown in Figure 5, the main implementation process includes:

[0381] Step 51, see step 31 of application scenario 1;

[0382] Step 52, see step 32 of application scenario 1;

[0383] Step 53: The E-SMLC maps the GNSS location information to the user location information, and obtains the ULI corresponding to the GNSS location information.

[0384] That is, in this implementation, the E-SMLC locally learns or stores the mapping relationship between the GNSS position and the ULI, performs the mapping locally, and the mapping relationship is configured in the MME.

[0385] Step 54: E-SMLC sends the ULI to MME.

[0386] In some embodiments, the E-SMLC sends a location response message (Location Response message) to the MME, where the location response message carries the ULI.

[0387] Step 55a: The MME sends the ULI to the access network device.

[0388] In some embodiments, the MME sends an S1-AP Transport message to the access network device, where the message carries the ULI.

[0389] Step 55b: The E-SMLC sends the ULI to the access network device.

[0390] In some embodiments, the E-SMLC sends an LPPa message to the access network device, where the message carries the ULI.

[0391] It should be noted that step 55a and step 55b are optional steps, and either one is performed, the purpose of which is to send the ULI to the access network device for the access network side to perform access management of the NTN.

[0417] Step 61c-2: The terminal sends positioning capability reply information to the E-SMLC, including sixth indication information, where the sixth indication information is used to indicate that the terminal does not support reporting GNSS position information.
