Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to an information processing method, apparatus, and communication device. Background Art

[0002] In a Non-Terrestrial Networks (NTN), after the network side obtains the location information of a terminal, mobility management of the terminal can be performed, including determining whether to allow service provision for the terminal. However, for a User Equipment (UE) to send location information through Radio Resource Control (RRC) signaling between the UE and the network, Access Stratum (AS) security is required. For NarrowBand Internet of Things (NB-IoT) devices with support for CP CIoT EPS Optimization only, in a satellite access scenario, the AS connection is not secured. Considering concerns about user privacy, the location information needs to be encrypted before being sent to the network side. However, the current mechanism for the terminal to report location information (here referring to Tracking Area Identity, TAI) is not applicable to NTN IoT UEs; how to implement location information reporting, access management, and mobility management for such UEs needs to be solved.

[0095] The related technologies of the embodiments of this application will be described as follows.

[0096] 1. Non-Terrestrial Networks (NTN) access

[0097] A non-terrestrial network refers to a network or network terminal that includes satellite or drone systems for communication transmission. The coverage area of a non-terrestrial network includes some typical communication scenarios and situations where it is impossible to build a terrestrial base station or the terrestrial base station is temporarily damaged, such as communication coverage in remote areas, deserts, oceans, virgin forests, or areas affected by fires and earthquakes. Satellite communication includes Low Earth Orbiting (LEO) satellites, Medium Earth Orbiting (MEO) satellites, Geostationary Earth Orbiting (GEO) satellites, and Highly Elliptical Orbiting (HEO) satellites.

[0098] Typical scenarios of non-terrestrial networks include the transparent relay type, where the satellite acts as a relay. The link between the satellite and the terminal is the service link, and the link between the satellite and the terrestrial base station is the feedback link.

[0099] II. Location verification

[0100] For conventional terminals (eMTC UE) accessing terrestrial networks (TN), after the terminal decides to access a certain cell during the access process of the access stratum (AS), the base station will learn the UE's resident cell information in the AS signaling. In TN access, a cell corresponds to a tracking area (TA) one by one. A cell ID uniquely corresponds to a tracking area identity (TAI, TAI is composed of a public land mobile network identity (PLMN ID) + a tracking area code (TAC)). In this way, the base station side can determine the current location information of the UE, which 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 the actual location of the UE.

[0101] After the UE determines the position of the Global Navigation Satellite System (GNSS), is it feasible to let the UE determine which TAI it is in? The answer is no, because for devices such as NTNIoT, saving a large number of mappings between locations and TAs will consume extra power. Currently, this mapping information (including the mapping between GNSS location and TAI, the mapping between cell and TAI, etc.) is stored on the network side, so the network is required to determine which TAI the UE is in.

[0102] 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 ULI information of the UE without the security of the AS.

[0103] The following will combine the accompanying drawings and elaborate on the information processing method, device, and communication equipment provided by the embodiments of the present application through some embodiments and their application scenarios.

[0104] As Figure 2 shown, an information processing method provided by an embodiment of the present application includes:

[0105] Step 201, a first core network device receives target location information sent by a terminal;

[0106] It should be noted that the target location information mentioned in the embodiments of the present application can be understood as geographical location information obtained by the terminal through a positioning method. Optionally, the geographical location information can be GNSS location information obtained by the terminal through GNSS positioning.

[0107] Optionally, the target location information may include at least one of the following:

[0108] A11. The longitude and latitude coordinate information of the geographical location where the terminal is located;

[0109] A12. The longitude and latitude coordinate information of the geographical location where the terminal is located after being coarsely processed;

[0110] Among them, the positioning accuracy of the longitude and latitude coordinate information of the geographical location where the terminal is located is higher than that of the longitude and latitude coordinate information of the geographical location where the terminal is located after being coarsely processed.

[0111] Here it should be noted 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 being coarsely processed. It should be noted that the positioning accuracy will decrease after the longitude and latitude coordinate information is coarsely processed, and its granularity can be between the longitude and latitude coordinates and the cell / tracking area (TA).

[0112] Step 202, the first core network device performs a target operation based on the target location information;

[0113] Optionally, the target operation includes at least one of the following:

[0114] A21. Obtain the user location information mapped by the target location information;

[0115] It should be noted that in this case, it means that the first core network device maps the target location information to user location information and obtains the user location information (ULI) corresponding to the target location information.

[0116] It should be noted that in this case, the mapping relationship between the target location information and the user location information is configured in the first core network device, and the first core network device can directly determine the user location information corresponding to the target location information based on this mapping relationship.

[0117] A22. Send the target location information to the second core network device;

[0118] 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, and the second core network device needs to obtain the user location information based on the target location information.

[0119] A23. Send the target location information to the target device, where the target device is an access network device or a mapping server;

[0120] 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, and this 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.

[0121] It should be noted that in the embodiments of the present application, by receiving the target location information sent by the terminal, the target location information is mapped to the user location information, and the user location information corresponding to the target location information is obtained, or the target location information is sent to the second core network device, and the second core network device obtains the user location information, or the target location information is sent to the target device, and the target device obtains the user location information, so as to realize the acquisition of the user location information of the terminal without AS security, and further perform access management and mobility management on such terminals.

[0122] Optionally, 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 serving mobile location center (E-SMLC), a location management function (LMF); the second core network device refers to a device capable of performing mobility and access management. For example, the first core network device can be an MME or an AMF, etc.

[0123] The following will separately elaborate on different target operations in detail as follows.

[0124] 1. The target operation includes A21

[0125] It should be noted that in this case, the first core network device maps the user location information by itself. Optionally, after the first core network device maps the user location information, in one implementation, the method further includes at least one of the following:

[0126] A121. The first core network device sends the user location information to the second core network device;

[0127] 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.

[0128] A122. The first core network device sends the user location information to the target device;

[0129] 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, it can assist the target device in configuring terminal transmission parameters and ensure the communication reliability of the terminal.

[0130] II. The target operation includes A22

[0131] 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.

[0132] Optionally, the manner for the second core network device to obtain the user location information may include one of the following:

[0133] A221. The second core network device maps the target location information to the user location information to obtain the user location information corresponding to the target location information;

[0134] It should be noted that in this case, the mapping relationship between the target location information and the user location information is configured in the second core network device, and the second core network device can directly determine the user location information corresponding to the target location information based on the mapping relationship.

[0135] Optionally, in this case, in one implementation, the method further includes:

[0136] The second core network device sends the user location information corresponding to the target location information to the target device;

[0137] 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, it can assist the target device in configuring terminal transmission parameters and ensure the communication reliability of the terminal.

[0138] A222. The second core network device sends target location information to the target device, and the second core network device receives the user location information corresponding to the target location information sent by the target device.

[0139] 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, and this mapping relationship is configured in the target device. The target device needs to obtain the user location information based on the target location information and feedback it to the second core network device.

[0140] Optionally, in this case, after receiving the target location information, the target device maps the target location information to the user location information according to 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.

[0141] III. The target operation includes A23

[0142] It should be noted that in this case, the target device needs to obtain the user location information based on the target location information.

[0143] Optionally, in one implementation manner, the specific implementation of sending the target location information to the target device includes:

[0144] The first core network device sends a target message to the target device;

[0145] Wherein, the target message includes the target location information; or,

[0146] The target message includes the target location information and the target indication information, and the target indication information is used to request the user location information mapped by the target location information.

[0147] Optionally, when the target device obtains the target indication information, it determines that it needs to perform the mapping of the target location information to obtain the user location information; optionally, when the target device obtains the target indication information, it determines that it needs to perform the mapping of the target location information to obtain the user location information, and replies to the first core network device with the user location information.

[0148] Optionally, the target message can be a newly introduced message for indicating the location mapping of the target location information. In this case, the target message can only include the target location information; optionally, the target message can also be a reused existing message. In this case, the target message needs to include the target location information and the target indication information so that the target device can clearly know which subsequent actions need to be performed after receiving the target message.

[0149] Optionally, after receiving the target location information, the target device maps the target location information to user location information according to 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.

[0150] It should be noted here that in one case, if the target device sends user location information to the first core network device, then in one implementation, the method further includes:

[0151] The first core network device receives the user location information corresponding to the target location information sent by the target device.

[0152] Further, after the first core network device obtains the user location information, optionally, in one implementation, the method further includes:

[0153] The first core network device sends the user location information to the second core network device.

[0154] 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.

[0155] It should be noted here that in another case, if the target device sends user location information to the second core network device, then in one implementation, the method further includes:

[0156] The target device sends confirmation information to the first core network device, and 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.

[0157] Here, it can be understood that since the user location information is used by the second core network device, that is to say, 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 can clearly know the subsequent execution process. This method can reduce the signaling overhead.

[0158] The relevant content of reporting the target location information is described in detail as follows.

[0159] Optionally, the terminal sends the target location information to the first core network device according to the second condition;

[0160] Wherein, the second condition includes at least one of the following:

[0161] 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;

[0162] In this way, it can be understood that the terminal sends the target location information based on the request of the first core network device.

[0163] Optionally, the first information includes at least one of the following:

[0164] B111. Location accuracy, which is used to indicate the positioning accuracy of the target location information reported by the terminal;

[0165] B112. First indication information, which is used to instruct the terminal to report target location information;

[0166] B113. Second indication information, which is used to instruct the positioning method adopted by the terminal to obtain the target location information;

[0168] B114. Third indication information, which is used to instruct the message encapsulation method for the terminal to report target location information;

[0169] For example, the message encapsulation method may include but is not limited to: encapsulation through Long-Term Evolution Positioning Protocol (LPP) messages, encapsulation with Non-Access Stratum (NAS) messages.

[0170] Optionally, in one implementation, the first core network device sends the first information to the terminal under a first condition, where the first information is used to instruct the terminal to report target location information;

[0171] Among them, the first condition includes at least one of the following:

[0172] C11. Receiving second information sent by a second core network device, where the second information is used to trigger the first core network device to obtain the target location information of the terminal;

[0173] Optionally, the second information includes at least one of the following:

[0174] C111. Fourth indication information, which is used to instruct the first core network device to obtain the target location information of the terminal;

[0175] It should be noted that the fourth indication information can be an explicit indication or an implicit indication. In the case of implicit indication, the fourth indication information is not included in the second information, that is, the second core network device can use a dedicated piece of information to request the first core network device to obtain the target location information, that is, the type of information can implicitly indicate that the first core network device obtains the target location information of the terminal.

[0176] C112. Trigger type, which is used to indicate the reason for the second core network device to send the second information;

[0177] Optionally, the trigger type can be non-terrestrial network location verification (NTN location verification) or network initiated location request (NI-LR).

[0178] C113. Location accuracy, which is used to indicate the positioning accuracy of the target location information reported by the terminal;

[0179] One implementation is co-ordinate or coarse co-ordinate (coarse co-ordinate can be understood as a location information after fuzzification processing based on the satellite longitude and latitude coordinates obtained by the GNSS module, and the granularity of this location is between longitude and latitude coordinates and cell / TA).

[0180] C114. Positioning method used to obtain the target location information of the terminal;

[0181] One implementation is GNSS. If not provided, E-SMLC determines it after receiving.

[0182] C115. Requested location information, which indicates the location description method of the terminal expected by the second core network device. This location description method can be understood as the description granularity of the location, the expression granularity of the location, etc.;

[0183] Optionally, the location description method includes at least one of the following:

[0184] C1151. Cell global identity (CGI);

[0185] Optionally, the cell global identity can be, for example, E-UTRAN CGI, NR CGI, etc. The CGI can include the NTN CGI where the terminal is located and the CGI mapped to the ground where the terminal is located.

[0187] C1153. Primary Serving Cell Information;

[0188] C1154. Primary and Secondary Cell Information;

[0189] C1155. Serving Public Land Mobile Network (Serving PLMN);

[0190] C1156. Tracking Area Code (TAC).

[0191] C116. Indication of whether satellite access is allowed;

[0192] It can be understood that the requested location information is used to indicate that the second core network device expects to describe the location of the terminal using at least one of C1151 - C1156.

[0193] It should be noted that this indication of whether satellite access is allowed can be understood as being used to indicate that the first core network device determines whether to allow the terminal to perform satellite access based on location information such as the region (country), TA, cell, or GNSS coordinates where the terminal is located.

[0194] Optionally, this second piece of information can be sent through the existing NI - LR location authentication process. For example, this second piece of information is included in the Location Request message sent by the second core network device to the first core network device.

[0195] Alternatively, this second piece of information can also be transmitted through a new NI - LR process. For example, it can be transmitted through a newly added dedicated message, and this dedicated message is a message for requesting ULI.

[0196] C12. Determine that the terminal supports reporting target location information;

[0197] Optionally, the terminal's support for reporting target location information can include at least one of the following understanding methods:

[0198] The terminal supports reporting target location information without access stratum security;

[0199] The terminal supports reporting target location information through LPP;

[0200] The terminal supports reporting target location information through NAS messages.

[0201] Optionally, in one implementation of this case, the method further includes:

[0202] The first core network device sends a positioning capability query request message to the terminal;

[0203] The first core network device receives the positioning capability reply message sent by the terminal;

[0204] Wherein, the positioning capability reply message includes one of the following:

[0205] A fifth indication message, which is used to indicate that the terminal supports reporting target location information;

[0206] A sixth indication message, which is used to indicate that the terminal does not support reporting target location information;

[0207] Optionally, the terminal not supporting reporting target location information may include at least one of the following understanding methods:

[0208] The terminal does not support reporting target location information without access stratum security;

[0209] The terminal does not support reporting target location information through LPP;

[0210] The terminal does not support reporting target location information through NAS messages.

[0211] It should be noted that if the positioning capability reply message received by the first core network device contains the fifth indication message, it means that the terminal can provide target location information for the first core network device. At this time, the first core network device can send a first message to the terminal to request target location information. If the positioning capability reply message received by the first core network device contains the sixth indication message, it means that the terminal cannot provide target location information for the first core network device. At this time, the first core network device cannot send the first message to the terminal.

[0212] Here, it should also be noted that if the terminal receives the first message from the first core network device, but the terminal determines that it cannot provide target location information. Optionally, in one implementation, the method further includes:

[0213] The first core network device receives a first rejection message sent by the terminal, and the first rejection message is used to indicate that the terminal cannot provide target location information.

[0214] That is to say, when the terminal cannot provide 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.

[0215] Optionally, in one implementation, the first rejection message includes a first cause value, and the first cause value is used to characterize the reason for being unable to provide the target location information of the terminal, including at least one of the following:

[0216] The terminal does not support reporting the target location information;

[0217] The terminal refuses to report the target location information due to user privacy.

[0218] Optionally, in one implementation, the first rejection message is carried in an attach request message or an attach complete message or an attach reject message or a registration request message or a registration complete message or a registration reject message or a tracking area update request message or a security mode complete message or a security mode reject message or an uplink generic NAS transport message or an 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) (e.g., LPP container).

[0219] Further optionally, if the terminal sends a first rejection message to the first core network device, then when the first core network device receives a second message 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, and the second rejection message is used to indicate that the target location information of the terminal cannot be provided.

[0220] Optionally, in one implementation, if the first core network device receives a second message and the second message carries fourth indication information, the first core network device can reply to the second core network device with a second rejection message.

[0221] Optionally, the second rejection message includes a second cause value, and the second cause value is used to characterize the reason for being unable to provide the target location information of the terminal, including at least one of the following:

[0222] The terminal does not support reporting target location information;

[0223] The terminal refuses to report target location information due to user privacy.

[0224] B12. The terminal receives third information sent by a second core network device, and the third information is used to instruct the terminal to report target location information;

[0225] In this way, it can be understood that the terminal sends the target location information based on the request of the second core network device.

[0226] Optionally, the third information includes at least one of the following:

[0227] B121. Location accuracy, which is used to indicate the positioning accuracy of the target location information reported by the terminal;

[0228] B122. Seventh indication information, which is used to instruct the terminal to report target location information with target accuracy;

[0229] B123. Eighth indication information, which is used to instruct the positioning method adopted by the terminal to obtain target location information with target accuracy;

[0230] Optionally, the positioning method includes but is not limited to: GNSS positioning, Galileo satellite navigation positioning, Beidou positioning, etc.

[0231] B124. Ninth indication information, which is used to instruct the message encapsulation method of the terminal to report target location information;

[0232] For example, the message encapsulation method may include but is not limited to: encapsulation through Long-Term Evolution Positioning Protocol (LPP) messages, encapsulation with Non-Access Stratum (NAS) messages.

[0233] Optionally, in one implementation, the second core network device needs to receive the capability information sent by the terminal, and the capability information is used to indicate whether the terminal supports reporting target location information. The second core network device can send the third information to the terminal only when it determines that the terminal supports reporting target location information.

[0234] Optionally, if the terminal receives the third information sent by the second core network device, but the terminal cannot provide target location information, in one implementation, 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 cannot provide target location information.

[0235] 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 sent to the second core network device.

[0236] 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 sent to the second core network device.

[0237] 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.

[0238] Optionally, the third rejection message includes a third cause value, which is used to characterize the reason for being unable to provide the target location information of the terminal and includes at least one of the following:

[0239] The terminal does not support reporting the target location information;

[0240] The terminal refuses to report the target location information due to user privacy.

[0241] B13. The terminal decides to report the target location information;

[0242] It should be noted that in this case, it can be understood that the terminal itself decides to report the target location information to the network, that is, the terminal actively reports the target location information to the network. For example, in one implementation: the terminal triggers the reporting of the target location information due to satellite access, and the accuracy is the default accuracy (such as co-ordination); in another implementation: the terminal resides in an NTN cell, and the terminal must report the target location information, and the accuracy is the default accuracy.

[0243] In summary, the situations where the terminal reports the target location information can be summarized as the following:

[0244] Scenario 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. The terminal feeds back target location information according to the first information.

[0245] Scenario 2: The second core network device sends third information to the terminal. The terminal feeds back target location information according to the third information.

[0246] Scenario 3: The first core network device sends a positioning capability query request message to the terminal; the terminal feeds back a positioning capability reply message according to the positioning capability query request message; the first core network device sends first information to the terminal according to the positioning capability reply message, and the terminal feeds back target location information according to the first information.

[0247] Scenario 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. The terminal feeds back target location information according to the third information.

[0248] Scenario 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 according to the capability information. The first core network device sends first information to the terminal according to the second information. The terminal feeds back target location information according to the first information.

[0249] Scenario 6: The terminal locally decides to send target location information.

[0250] Optionally, in one implementation, the user location information described in the embodiments of the present application includes at least one of the following:

[0251] D11. Cell Global Identity;

[0252] D12. Tracking Area Identity;

[0253] D13. Primary Serving Cell Information;

[0254] D14. Primary and Secondary Cell Information;

[0255] D15. Serving Public Land Mobile Network;

[0256] D16. Tracking Area Code.

[0257] Taking the first core network device as the E-SMLC, the second core network device as the MME, the target device as the access network device, and the terminal reporting GNSS location information as an example, the specific implementation of the present application is illustrated as follows.

[0258] Application Scenario 1: The E-SMLC interacts with the RAN to obtain ULI

[0259] As Figure 3 shown, the main implementation process includes:

[0260] Step 31, the network triggers or the terminal locally decides to perform GNSS location information reporting;

[0261] There are mainly the following implementation methods, and one method can be selected based on requirements:

[0262] Method 1,

[0263] Step 31a-1, the MME sends a second piece of information to the E-SMLC, and the second piece of information is used to trigger the E-SMLC to obtain the GNSS location information of the terminal;

[0264] Optionally, the second piece of information can be sent through a first trigger message, which is used to trigger the E-SMLC to collect the location of the terminal for location confirmation, and the message carries:

[0265] An associated ID, which is used to uniquely identify a session of location confirmation;

[0266] The second piece of information.

[0267] Optionally, the second piece of information includes at least one of the following:

[0268] A fourth indication message, which is used to indicate that the first core network device obtains the GNSS location information of the terminal;

[0269] A trigger type, which is used to indicate the reason for the second core network device to send the second piece of information;

[0270] A location accuracy, which is used to indicate the positioning accuracy of the target location information reported by the terminal;

[0271] A positioning method used to obtain the GNSS location information of the terminal;

[0272] Requested location information, which indicates the location description method expected by the second core network device for the terminal;

[0273] An indication of whether satellite access is allowed.

[0274] One implementation method is that the first trigger message is carried in the Location Request message from the MME to the E-SMLC.

[0275] It should be noted that the content in the requested location information can be default configured, for example, it includes all the above ULI information, or it includes the content except the result indication of whether satellite access is allowed.

[0276] Step 31a-2: After the E-SMLC receives the second information from the MME, it determines a positioning method (such as GNSS positioning), and the E-SMLC sends the first information to the terminal, where the first information is used to instruct the terminal to report GNSS location information;

[0277] Optionally, the first information can be sent through a first message, and the first message includes:

[0278] Association ID;

[0279] First information.

[0280] Optionally, the first information includes at least one of the following:

[0281] Position accuracy, which is used to indicate the positioning accuracy of the GNSS location information reported by the terminal;

[0282] First indication information, which is used to instruct the terminal to report GNSS location information;

[0283] Second indication information, which is used to instruct the positioning method adopted by the terminal to obtain GNSS location information;

[0284] Third indication information, which is used to instruct the message encapsulation method for the terminal to report GNSS location information.

[0285] It should be noted that in one implementation, the E-SMLC passes the first information to the terminal through an LPP message. The message is sent from the E-SMLC to the MME and then forwarded to the UE, and the message is carried in the N1 container.

[0286] 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).

[0287] Method 2

[0288] Step 31b: The MME sends the third information to the terminal;

[0289] The third information can be sent through a second message, and the second message carries:

[0290] Association ID;

[0291] Third information.

[0292] Optionally, the third information includes at least one of the following:

[0293] Position accuracy, which is used to indicate the positioning accuracy of the GNSS location information reported by the terminal;

[0294] The seventh indication information, which is used to indicate that the terminal reports GNSS location information with a target accuracy;

[0295] The eighth indication information, which is used to indicate the positioning method adopted by the terminal to obtain GNSS location information with a target accuracy;

[0296] The ninth indication information, which is used to indicate the message encapsulation method for the terminal to report GNSS location information.

[0297] It should be noted that after receiving the second message, the terminal obtains GNSS location information through the GNSS positioning method.

[0298] In one implementation, the second information is sent to the terminal in an attach accept message or a tracking area update accept message or a downlink generic NAS transport message or a Downlink NAS Transport message.

[0299] Method 3:

[0300] Step 31c: The terminal itself decides to report the GNSS location information to the network.

[0301] One implementation is as follows: The terminal triggers the reporting of GNSS location information due to satellite access, and the accuracy is the default accuracy (such as co-ordination); when the terminal camps on the NTN cell, the terminal must report the GNSS location information, and the accuracy is the default accuracy.

[0302] Method 4:

[0303] Step 31d-1: The E-SMLC sends a positioning capability query request message to the terminal, aiming to obtain the positioning capability of the terminal.

[0304] One implementation is achieved through the LPP capability transfer procedure, that is, the E-SMLC sends a RequestCapabilities message to the terminal.

[0305] In one implementation, this step is optional, that is, if this step does not occur, the terminal directly proceeds to step 1d-2, and the E-SMLC executes step 1d-3.

[0306] 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:

[0307] The fifth indication information, which is used to indicate that the terminal supports reporting GNSS location information.

[0308] One implementation is achieved through the LPP capability transfer procedure, that is, the terminal sends a ProvideCapabilities message.

[0309] Step 31d-3: When the E-SMLC supports reporting GNSS location information according to the capabilities in step 31d-3, the E-SMLC sends the first information to the terminal.

[0310] For other content of this step, it is the same as step 31a-2 and will not be elaborated here.

[0311] Method Five

[0312] Step 31e-1: The terminal sends capability information to the MME, and the capability information is used to indicate whether the terminal supports reporting GNSS location information.

[0313] One implementation is that the capability information is carried in an attach request message or an attach complete message or a tracking area update request message or an uplink generic NAS transport message or an uplink NAS Transport message and sent to the MME.

[0314] It should be noted that after receiving the terminal's capability information, the MME may optionally carry it to the E-SMLC in step 3a-1 and inform the E-SMLC of the terminal's capabilities, so that the E-SMLC can select whether to execute step 3a-2 according to the terminal's capabilities when performing step 3a-1. One implementation is that when the terminal's capability information is not carried in step 3a-1 and the capability information indicates that the terminal supports reporting location information without AS security or reporting GNSS location through LPP, the E-SMLC can send the first information to the terminal.

[0315] Step 31e-2: According to the terminal's capability information, when the terminal's capability information supports reporting GNSS location information, the MME sends the third information to the terminal.

[0316] For other content of this step, it is the same as step 3b and will not be elaborated here.

[0317] Step 32: The terminal sends GNSS location information to the E-SMLC;

[0318] Optionally, the GNSS location information may be carried in a third message. The GNSS location information is carried in the third message. Further, the following at least one item may also be carried in the third message:

[0319] Associated ID;

[0320] The ability of the terminal to support reporting GNSS location information;

[0321] An indication that the location information needs to be mapped to the access network for location and obtain the ULI, for location verification under NTN access;

[0322] Access network device identifier, representing the identification information of the access network device of the current service, such as device ID, etc.;

[0323] GNSS accuracy information, indicating the accuracy of the GNSS location information, such as co-ordination or coarse co-ordination.

[0324] One implementation 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 may be encapsulated in a newly created IE or a payload container IE (for example: LPP container). And an indication information may be included in the access request message to indicate that the newly created IE or the payload container carries the GNSS location for NTN location verification. After receiving it, 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.

[0325] Step 33: After receiving the GNSS location information, the E-SMLC sends the GNSS location information to the serving access network device or the mapping server of the terminal;

[0326] Optionally, the GNSS location information may be sent through a target message which carries the GNSS location information; further, the target message may also carry at least one of the following:

[0327] Associated ID;

[0328] Target indication information which is used to request the user location information mapped by the target location information.

[0329] It should be noted that the mapping server with the location mapping support capability exists in the core network element or network server. The E-SMLC queries the network element or server for this capability to obtain the address of the mapping server, and sends the target message to the corresponding mapping server to request GNSS location mapping. Here, the mapping server is a dedicated server (including a base station or network element), not specifically referring to a certain base station.

[0330] It should be noted that the E-SMLC can determine the serving base station of the terminal based on the GNSS location reported by the terminal and send the target message to it; or the E-SMLC determines the serving base station according to the base station identification information carried in the third message.

[0331] In one implementation, the target message is encapsulated in the S1-AP Transport message and sent to the MME. The MME then forwards it to the base station. The target message may be a Long-Term Evolution (LTE) Positioning Protocol A (LPPa) message.

[0332] Step 34: The access network device or the mapping server maps the received GNSS location information and outputs the ULI.

[0333] Step 35: The access network device or the mapping server sends the ULI;

[0334] Optionally, after the access network device or the mapping server completes the GNSS mapping, there are the following two implementation methods:

[0335] Implementation method 35a: The access network device or the mapping server sends the mapped ULI to the E-SMLC, and the E-SMLC then sends it to the MME;

[0336] Specifically including:

[0337] Step 35a-1: The access network device or the mapping server sends the mapped ULI to the E-SMLC;

[0338] Optionally, the ULI may be sent through the fifth message.

[0339] Optionally, the fifth message may be sent via LPPa signaling.

[0340] In addition to the ULI, the fifth message may further include: an association ID.

[0341] In one implementation, the fifth message is encapsulated in an S1-AP Transport message and sent to the MME, and the MME then forwards it to the E-SMLC. The fifth message may be an LPPa message.

[0342] Step 35a-2: The E-SMLC sends the mapped ULI to the MME for location confirmation, and the E-SMLC sends a sixth message to the MME, where the sixth message carries:

[0343] Association ID;

[0344] ULI;

[0345] Result indication, indicating whether the terminal can be allowed to access the NTN network, including one of: allowed, rejected.

[0346] In one implementation, when the MME carries the "result indication of whether satellite access is allowed" in the request of step 3a-1, the E-SMLC locally confirms whether the ULI (e.g., TAI, cell ID) where the UE is located can support the access of the terminal, and returns a result indication to the MME: allowed, rejected; to indicate that the terminal is allowed to access or rejected from accessing the NTN.

[0347] In one implementation, the sixth message is carried in the Location Response message from the E-SMLC to the MME.

[0348] Implementation 35b: The access network device or the mapping server directly sends the mapped ULI to the MME, and optionally notifies the E-SMLC that it has received the GNSS location information;

[0349] Specifically including:

[0350] Step 35b-1: The access network device or the mapping server sends the mapped ULI to the MME;

[0351] Optionally, the access network device or the mapping server sends a seventh message to the MME, and the seventh message carries:

[0352] Association ID;

[0353] ULI.

[0354] In one implementation, in step 33, when the E-SMLC carries the target indication information in the target message, the target message may optionally carry MME identification information, such as GUMMEI. In another implementation, the access network device or the mapping server understands that the target indication information used to indicate the location mapping of the GNSS location information and reply the ULI is: by default, the ULI information is sent to the MME after the GNSS is executed. Therefore, after the access network device or the mapping server completes the mapping of the GNSS location information, it sends the ULI information to the MME. In addition, the target message may optionally carry MME identification information, such as GUMMEI.

[0355] In one implementation, the seventh message is encapsulated in the S1-AP Transport message and sent to the MME.

[0356] Step 35b-2: The access network device or the mapping server sends a confirmation message to the E-SMLC, and the confirmation message is used to indicate that the user location information corresponding to the GNSS location information has been sent to the second core network device.

[0357] It should be noted that this step is an optional step.

[0358] Optionally, the determination information can be sent through the eighth message to confirm 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.

[0359] In one implementation, the eighth message is encapsulated in the S1-AP Transport message and sent to the MME. The MME then forwards it to the E-SMLC. The eighth message can be an LPPa message.

[0360] Application scenario 2: The MME interacts with the RAN to obtain the ULI

[0361] As Figure 4 shown, the main implementation process includes:

[0362] Step 41: Refer to step 31 in Application scenario 1.

[0363] Step 42: Refer to step 33 in Application scenario 1.

[0364] Step 43: After receiving the GNSS location information, the E-SMLC sends the GNSS location information to the MME.

[0365] Step 44: The MME obtains the ULI corresponding to the GNSS location information.

[0366] Among them, this step can be implemented in one of the following two ways:

[0367] Method 1:

[0368] Specifically, it includes:

[0369] Step 44a, the MME performs the mapping of the GNSS location information to the user location information, and obtains the ULI corresponding to the GNSS location information;

[0370] That is to say, in this implementation method, the MME locally learns or stores the mapping relationship between the GNSS location and the ULI, and performs the mapping locally, and the mapping relationship is configured in the MME.

[0371] Method 2:

[0372] Specifically, it includes:

[0373] Step 44b-1, the MME sends the GNSS location information to the service access network device or the mapping server of the terminal;

[0374] Optionally, the GNSS location information can be sent through the ninth message, and an indication for performing location mapping on the GNSS location information and replying with the ULI can also be carried in the ninth message; an optional implementation method is: the MME sends an S1-AP Transport message.

[0376] Optionally, the ULI can be sent through the tenth message, and the ULI is carried in the tenth message; an optional implementation method is: the access network device or the mapping server sends an S1-AP Transport message.

[0382] That is to say, in this implementation mode, the E-SMLC locally learns or stores the mapping relationship between the GNSS location and the ULI, performs the mapping locally, and the mapping relationship is configured in the MME.

[0383] Step 54: The E-SMLC sends the ULI to the MME;

[0384] Optionally, the E-SMLC sends a Location Response message to the MME, and the ULI is carried in the location response message.

[0385] Step 55a: The MME sends the ULI to the access network device;

[0388] Optionally, the E-SMLC sends an LPPa message to the access network device, and the ULI is carried in the message.

[0389] It should be noted that Step 55a and Step 55b are optional steps, and only one of them is executed. The purpose is to send the ULI to the access network device for the access network side to perform NTN access management.
