[0098] S402: The core network device receives fifth information from the access network device, where the fifth information includes location information of the terminal; wherein AS security of the terminal is not used or AS security is not activated.

[0099] In an embodiment of the present application, when the AS security of the terminal is not used or the AS security is not activated, the terminal can also report location information, which is beneficial for assisting the network side to manage the mobility of the terminal and improve the performance of the communication system.

[0106] Optionally, as an embodiment, the method further includes: the core network device receiving a fourth indication from the access network device, the fourth indication being used to instruct the core network device to perform security processing on the fifth information.

[0107] To illustrate in detail the method for reporting location information provided in the embodiments of the present application, several specific embodiments will be described below.

[0108] Example 1

[0109] In this embodiment, the network instructs the terminal to report location information, but the terminal does not report location information. As shown in Figure 5, this embodiment includes the following steps:

[0110] Step 1: The terminal obtains first information from the first cell, where the first information is used to instruct the terminal to report location information.

[0111] The first information may include a first indication, and the meaning of the first indication includes one of the following: 1) the network requests the terminal to report the location information; 2) the network enables the terminal to report the location information.

[0112] The first indication may be an explicit indication or an implicit indication. For example, if the first information includes any information related to location reporting (such as first area information and / or service-related information), it may implicitly indicate the network to request the terminal to report location information. If it is an explicit indication, the first indication may be represented by 1 bit. Specifically, for example, if the value of the bit is 1 or true, it indicates that the network requests the terminal to report location information. If the value of the bit is 0 or false, it indicates that the terminal does not need to report location information. For another example, if the bit exists and the value is true, it indicates that the network requests the terminal to report location information.

[0113] Additionally, if the terminal wants to reside in or access the cell (ie, the cell that sends the first information, which is the first cell in this embodiment), the terminal must report location information.

[0114] In this embodiment, if a cell provides a first indication and the terminal has a first capability, the terminal may perform a first action, where the first action includes at least one of the following: 1) determining that the first cell is a suitable cell; 2) determining that the first cell is a candidate cell for cell selection or reselection; or 3) determining that the first cell is not barred. The first condition includes at least one of the following: 1) the terminal has the first capability; 2) the terminal decides to report its location information; 3) the terminal is unwilling to report its location information; or 4) the terminal's location information is available. This embodiment is applicable to situations where a terminal reports its location information.

[0115] In this embodiment, if a cell provides a first indication and a terminal is willing or determined to report its location information, the terminal may perform a first action, where the first action includes at least one of the following: 1) determining that the first cell is a suitable cell; 2) determining that the first cell is a candidate cell for cell selection or reselection; or 3) determining that the first cell is not barred. The first condition includes at least one of the following: 1) the terminal has a first capability; 2) the terminal determines to report its location information; 3) the terminal is unwilling to report its location information; or 4) the terminal's location information is available. This embodiment is applicable to situations where a terminal reports its location information.

[0116] It is understood that deeming the cell to be a suitable cell also includes determining whether the cell is a suitable cell based on other suitable cell determination conditions in existing mechanisms (e.g., the cell is not prohibited). Furthermore, the above two items can be combined, that is, if the cell provides the first indication, the terminal has the first capability, and the terminal is willing and determined to report the terminal's location information, the terminal performs the first action.

[0117] In this embodiment, if the cell provides the first indication and the terminal does not have the first capability, the terminal may perform a second action, which includes at least one of the following: 1) deeming the first cell not a suitable cell; 2) deeming the first cell not a candidate cell for cell selection or reselection; 3) deeming the first cell to be barred, and additionally deeming the cell to be barred within a second time, for example, the first cell to be barred within 300 seconds; 4) deeming that only limited services are available on the first cell. This embodiment is applicable to situations where the terminal does not report location information.

[0118] Similarly, it is understandable that if it is considered that only limited services can be obtained on the cell, it also includes determining whether the cell is an acceptable cell according to other determination conditions of acceptable cells in the existing mechanism.

[0119] In this embodiment, if the cell provides a first indication and the terminal is unwilling to report location information / decides not to report location information, the terminal performs a second action, which includes at least one of the following: 1) deeming the first cell not a suitable cell; 2) deeming the first cell not a candidate cell for cell selection or reselection; 3) deeming the first cell to be barred, and additionally deeming the cell to be barred within a second time, for example, the first cell to be barred within 300 seconds; 4) deeming that only limited services are available on the first cell. This embodiment can be applied to situations where the terminal does not report location information.

[0120] The first capability mentioned in the above two embodiments may include at least one of the following: 1) the ability to report the location information of the terminal when AS security is not used or AS security is not activated; 2) the ability to report the location information of the terminal in a first process, and the first process includes at least one of the RRC connection establishment process, the RRC connection recovery process, the RRC connection reconstruction process, the switching process and the EDT process.

[0121] The first capability is an optional capability, which does not need to be indicated to the network (Optional without singalling).

[0122] Additionally, the first information may further include at least one of the following:

[0123] 1) First area information, used to indicate in which areas the terminal needs to report location information, the area information of the terminal includes at least one of the following: at least one TAI (Tracking area identify) (including PLMN ID and TAC); at least one CGI (Cell Global Identifier) ​​(including PLMN ID and Cell ID); at least one second information, the second information including carrier frequency information and at least one physical cell identifier (Physical Cell Identifier, PCI); at least one geographic location area, for example, a geographic location area can be identified by a reference point (represented by a geographic coordinate) and a distance threshold, for example, a geographic location area can be identified by multiple geographic coordinates; at least one RAN area (identified by a RAN area ID) (including a TAC and a RAN area code).

[0124] 2) Service-related information, used to indicate the services for which the terminal needs to report its location information, including at least one of the following: emergency services, high-priority access services (related to AC 11.15), mobile terminating-access services (mt-Access), mobile originating signaling services (mo-Signalling), mobile originating data services (mo-Data), delay-tolerant access services (delayTolerantAccess-v1020), voice call services (mo-VoiceCall-v1280), delay-sensitive services, conversational services, streaming media services, interactive services, and background services.

[0125] In addition, the terminal needs to perform the first behavior or the second behavior only if it fails to report location information as requested by the network side within the first area. The first area can be determined by protocol agreement or configured by the network side (for example, indicated in the first information); the terminal needs to perform the first behavior or the second behavior only if the service type initiated by the terminal is a certain specific service type. The specific service type can be determined by protocol agreement or configured by the network side (for example, indicated in the first information).

[0126] The reporting of location information also includes at least one of the following: 1) reporting location information when AS security is not activated or not used; 2) reporting location information during a first process, wherein the first process includes at least one of an RRC connection establishment process, an RRC connection recovery process, an RRC connection re-establishment process, a handover process, and an Early Data Transmission (EDT) process. This embodiment allows the network side to obtain the terminal's location information as early as possible, which helps the network side to determine whether to allow service to the terminal as early as possible.

[0127] The location information includes at least one of the following: 1) coarse location information, such as coarseLocationInfo, encoded by Ellipsoid-Point IE; 2) precise / detailed location information, such as LocationInfo.

[0128] The first information may be provided through system message broadcast (for specific signaling format, see embodiment 5) or paging message or dedicated signaling.

[0129] Step 2: The AS of the terminal submits the first information to the NAS.

[0130] Additionally, if the first information is common for all PLMNs and NPNs, the terminal submits the first information; if the first information is specific per PLMN or SNPN, the terminal submits the first information in PLMN-IdentityInfo / NPN-IdentityInfo including the selected PLMN / SNPN to the NAS.

[0131] Step 3: If the terminal does not report the location information, the terminal may send a third message to the network, where the third message is used to indicate at least one of the following: 1) the terminal is unwilling to report the location information of the terminal; 2) the terminal decides not to report the location information of the terminal; 3) the location information of the terminal is not available (UE location is not available).

[0132] Additionally, the third information may further include information about a second time, where the second time information is used to indicate a time when the terminal is unwilling to report the terminal's location information, or a time when the terminal decides not to report the terminal's location information, or a time when the terminal's location information is unavailable. The time may be a timestamp (specific time) or a time interval, etc.

[0133] Additionally, the second information may further include second area information, where the second area information is used to indicate an area where the terminal is unwilling to report the location information of the terminal, or an area where the terminal decides not to report the location information of the terminal, or an area where the location information of the terminal is unavailable.

[0134] The third information can be reported in Msg3 or msg5. The third information can be RRC information, or a new MAC CE can be introduced, including the third information. It can be understood that the content of the third information can be empty, that is, the third information does not include the second time information and the second area information. The MAC CE is identified by a MAC PDU subheader with LCID / ELCD and has a fixed length of 0 bits (It has a fixed size of zero bits).

[0135] It is understandable that if the network configures / requests / enables the terminal to report location information, the terminal does not have to report and can still perform existing processes, such as residing in the cell to perform RRC connection establishment process, uplink and downlink transmission, etc. Moreover, even if the terminal indicates that it does not want to report location information, the network can still request the terminal to report.

[0136] Additionally, if the terminal does not report location information, the method further includes: the NAS of the terminal indicating the third information to the AS of the terminal.

[0137] It can be understood that the entity that decides not to report the location information can be AS or NAS. If AS decides not to report, AS generates third information and sends it to the network; if NAS decides not to report, NAS generates third information and instructs AS, which then sends it to the network.

[0138] In addition, the terminal needs to send the third information only if it fails to report the location information as requested by the network side within the first area. The first area can be determined by protocol agreement or configured by the network side (for example, the first area information in the first information indicates); the terminal needs to send the third information only if the service type initiated by the terminal is a certain specific service type. The specific service type can be determined by protocol agreement or configured by the network side (for example, the service-related information in the first information indicates).

[0139] Optionally, the terminal mentioned in this embodiment is an NB-IoT terminal that only supports CP CIoT EPS / 5GS Optimization.

[0140] Example 2

[0141] In this embodiment, the terminal reports location information; the NAS performs security processing on the terminal's location information and provides the location information to the AS. The core network decodes the location information and determines the TAC where the terminal is located. As shown in FIG6 , this embodiment includes the following steps:

[0142] Step 1: The terminal obtains first information, which is used to instruct the terminal to report location information. The content of this step can be found in Step 1 of Example 1 and will not be repeated here.

[0143] Step 2: The NAS of the terminal securely processes the location information of the terminal and indicates fifth information to the AS, where the fifth information includes the securely processed location information, and the secure processing includes at least one of encryption or integrity protection.

[0144] Additionally, the NAS obtains the terminal's location information from an upper layer (eg, an APP layer).

[0145] It can be understood that the NAS layer generates NAS information including location information and performs security processing.

[0146] Before this step, the AS also sends fourth information to the NAS, where the fourth information includes the first information or the second indication, and the meaning of the second indication includes at least one of the following: 1) requesting the NAS of the terminal to securely process the location information of the terminal; 2) the terminal needs to send the location information of the terminal.

[0147] It is understandable that the AS layer may decide to send the location information and send information to instruct the NAS to process the location information, or the AS may only submit the received first information and the NAS may decide to send the location information.

[0148] Step 3: The terminal sends fifth information to the network. The fifth information is carried in an RRC message and includes the terminal's location information securely processed by the terminal's NAS. In this embodiment, when AS security is not used or activated, the terminal's NAS securely processes the terminal's location information, thereby improving the security of the terminal's location information.

[0149] Optionally, the RRC message is at least one of an RRC connection establishment complete message, an RRC connection recovery complete message, an RRC connection reestablishment complete message, an RRC connection reconfiguration complete message, an RRC connection establishment request message, an RRC connection recovery request message, an RRC connection reestablishment request message, and an RRC early data request (RRCEarlyDataRequest) message. It is understandable that this embodiment may also introduce a new RRC message that carries the fifth information.

[0150] The RRC message carrying the fifth information includes at least one of the following manners:

[0151] 1) Encapsulate the fifth information into a container.

[0152] 2) Concatenating the fifth information with the RRC message.

[0153] 3) The fifth information is piggybacked into the RRC message.

[0154] Step 4: The access network receives the fifth information and sends the fifth information to the core network.

[0155] Additionally, the user location information sent by the access network device to the core network device does not include the seventh information; wherein the fifth information includes the location information of the terminal; and the seventh information includes all TACs broadcast by cells under the access network device, where the TACs correspond to the serving network of the terminal. For example, the access network does not need to provide the TAC List in LTE NTN (see the table below) in the LTE NTN TAI Information to the core network.

[0156] If the access network provides LTE NTN TAI Information to the core network, the core network ignores the TAC List in LTE NTN (see the table below).

[0157] Additionally, if the access network provides TAI (see the table below) but does not provide LTE NTN TAI Information, the core network ignores TAI.

[0158] Step 5: The core network obtains the area information of the terminal based on the fifth information and the second mapping relationship. The second mapping relationship is configured in the core network. The area information of the terminal includes: a mapped cell identifier (Mapped Cell ID), that is, a Cell ID corresponding to a fixed ground area, the TAC where the terminal is located, the TAI where the terminal is located, and the CGI where the terminal is located.

[0159] The second mapping relationship includes at least one of the following: a mapping relationship between a cell identifier and a geographical area, a mapping relationship between a TAC and a geographical area, a mapping relationship between a TAI and a geographical area, and a mapping relationship between a CGI and a geographical area.

[0160] The second mapping relationship may be pre-configured (eg, depending on an operator's policy) or may be configured based on implementation.

[0161] Before this step, the core network also performs security decryption processing on the fifth information, and the security decryption processing includes at least one of decryption and integrity verification.

[0162] Example 3

[0163] In this embodiment, the terminal reports location information; wherein, the NAS of the terminal performs security processing on the location information of the terminal and provides the location information to the AS. The core network decodes the location information and indicates it to the RAN. The access network determines the TAC where the terminal is located. As shown in Figure 7, this embodiment includes the following steps:

[0164] For steps 1-4, please refer to steps 1-4 of the second embodiment.

[0165] Step 5: The core network sends eighth information to the access network, where the eighth information includes the location information of the terminal.

[0166] Before this step, the core network also performs security decryption processing on the fifth information, and the security decryption processing includes at least one of decryption and integrity verification.

[0167] It is understandable that after the core network obtains the location information of the terminal, it regenerates the eighth information (including the location information of the terminal) to send to the access network through the S1 or NG interface.

[0168] Step 6: The access network determines the area information where the terminal is located based on the location information of the terminal and a first mapping relationship, where the first mapping relationship is configured in the access network.

[0169] Step 7: The access network sends the obtained terminal area information to the core network, for example, through the User Location Information IE.

[0170] It is understandable that in the existing mechanism, the access network sends the User Location Information IE to the core network in some processes triggered by the core network, such as E-RAB Management procedures, specifically including the IE in the E-RAB SETUP RESPONSE message, E-RAB MODIFY RESPONSE message, E-RAB RELEASE RESPONSE message, E-RAB MODIFICATION INDICATION message, UE CONTEXT RELEASE COMPLETE message, UE CONTEXT SUSPEND REQUEST message, etc.

[0171] In this embodiment, in addition to triggering the access network to send the User Location Information IE to the core network during these processes, the core network also sends the terminal's location information to the access network, thereby triggering the access network to send the IE to the core network. In addition, a new S1AP message / NGAP message can be introduced to carry the User Location Information IE.

[0172] Example 4

[0173] In this embodiment, RRC generates RRC IE related to location information and submits it to NAS for security processing. NAS feeds back the RRC IE after security processing to AS. After receiving the location information, the access network sends it to the core network. The core network performs security processing and then feeds back to the access network. The access network determines the TAC where the terminal is located.

[0174] The difference between this embodiment and the second and third embodiments is that the location information in the second and third embodiments is essentially NAS information (generated and securely processed by the NAS), while the location information in this embodiment is generated by the AS and is an RRC IE, but is securely processed by the NAS layer. As shown in FIG8 , this embodiment includes the following steps:

[0175] Step 1: The terminal obtains first information, which is used to instruct the terminal to report location information. The content of this step can be found in Step 1 of Example 1 and will not be repeated here.

[0176] Step 2: The AS of the terminal sends sixth information to the NAS of the terminal, where the sixth information includes the location information of the terminal.

[0177] Additionally, the AS layer obtains the location information of the terminal from an upper layer (eg, an APP layer).

[0178] It can be understood that the sixth information can be RRC IE.

[0179] Additionally, the sixth information may further include a third indication for instructing the NAS to securely process the location information of the terminal. It is understood that, if there is no third indication, the AS only indicates the location information of the terminal, which may also implicitly indicate that the NAS needs to securely process the location information.

[0180] Step 3: The NAS of the terminal performs security processing on the location information of the terminal and sends the processed fifth information to the AS.

[0181] Step 4: The terminal sends fifth information to the network, where the fifth information is carried by an RRC message, and the RRC message is at least one of an RRC connection establishment complete message, an RRC connection recovery complete message, an RRC connection reestablishment complete message, an RRC connection reconfiguration complete message, an RRC connection establishment request message, an RRC connection recovery request message, an RRC connection reestablishment request message, and an RRC early data request (RRCEarlyDataRequest) message. It is understandable that this embodiment may also introduce a new RRC message to carry the fifth information.

[0182] Step 5: The access network receives the fifth information and sends the fifth information to the core network. Additionally, the access network sends a fourth instruction to the core network to instruct the core network to perform security decryption processing on the fifth information.

[0183] Step 6: The core network sends the fifth information after security processing to the access network.

[0184] Step 7: The access network determines the area information of the terminal based on the fifth information after the security processing and the first mapping relationship, where the first mapping relationship is configured in the access network.

[0185] Step 8: The access network sends the obtained terminal area information to the core network, for example, through the User Location Information IE.

[0186] It is understandable that the core network sends the location information of the terminal to the access network, thereby triggering the access network to send the IE to the core network.

[0187] Example 5

[0188] This embodiment mainly introduces the signaling format of providing the first information in a broadcast manner.

[0189] If broadcast through a system message, the first information can be provided in the system information used for scheduling including information related to evaluating whether the UE is allowed to access the cell and including other system information, such as SIB1 (system information in NR) / SystemInformationBlockType1 (system information in LTE) / SystemInformationBlockType1-MBMS (system information in LTE) / SystemInformationBlockType1-BR; it can also be provided in the system information including auxiliary information for NTN access, such as SIB19 (system information in NR) / SystemInformationBlockType31 / SystemInformationBlockType31-NB (system information in LTE).

[0190] If provided in SIB1 (system information in NR) / SystemInformationBlockType1 / SystemInformationBlockType1-MBMS (system information in LTE), taking the first information including the first indication as an example, there are the following methods:

[0191] 1) A field is extended in SIB1 to include the first information. The field is included in SIB1 and is parallel to other outermost fields (such as cellAccessRelatedInfo). Taking the first information including only the first indication as an example, the specific signaling format is as follows:

[0192] 2) This field is placed in cellAccessRelatedInfo. This field is common for all PLMNs and NPNs. Taking the first information including only the first indication as an example, the specific signaling structure is as follows:

[0193] The same is provided in SystemInformationBlockType1 / SystemInformationBlockType1-MBMS and will not be repeated here.

[0194] If provided in SIB19 / SystemInformationBlockType31 / SystemInformationBlockType31-NB, take SIB19 as an example.

[0195] 1) In the outermost layer of SIB19, it is listed alongside the satellite-related parameters required to access the serving cell (ntn-config of the serving cell). Taking the first information including only the first indication as an example, the specific signaling structure is as follows:

[0196] For SystemInformationBlockType31, taking the first information including only the first indication as an example, the specific signaling is as follows:

[0197] 2) In ntn-config / servingSatelliteInfo, additionally, this field is limited to exist only for the serving cell.

[0198] The location information reporting method provided in the embodiment of the present application can be executed by a location information reporting device. In the embodiment of the present application, the location information reporting method performed by the location information reporting device is taken as an example to illustrate the location information reporting device provided in the embodiment of the present application.

[0199] FIG9 is a schematic diagram of the structure of a device for reporting location information according to an embodiment of the present application, which can be applied to a terminal. As shown in FIG9 , the device 900 includes the following modules.
