[0105] 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.

[0106] Embodiment 1

[0107] In this embodiment, the network instructs the terminal to report the location information, but the terminal does not report the location information. Figure 5 As shown, this embodiment includes the following steps:

[0108] 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.

[0109] 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.

[0110] 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. 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 its value is true, it indicates that the network requests the terminal to report location information.

[0111] 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 the location information.

[0112] In this embodiment, when the cell provides a first indication and the terminal has a first capability, the terminal may perform a first behavior, wherein the first behavior includes at least one of the following: 1) the first cell is a suitable cell; 2) the first cell is considered to be a candidate cell for cell selection or reselection; 3) the first cell is considered not to be prohibited. The first condition includes at least one of the following: 1) the terminal has the first capability; 2) the terminal decides to report the location information of the terminal; 3) the terminal is unwilling to report the location information of the terminal; 4) the location information of the terminal is available. This embodiment may be applicable to the case where the terminal reports the location information.

[0113] In this embodiment, when the cell provides a first indication and the terminal is willing or determined to report the location information of the terminal, the terminal may perform a first behavior, wherein the first behavior includes at least one of the following: 1) the first cell is a suitable cell; 2) the first cell is considered to be a candidate cell for cell selection or reselection; 3) the first cell is considered not to be prohibited. The first condition includes at least one of the following: 1) the terminal has a first capability; 2) the terminal decides to report the location information of the terminal; 3) the terminal is unwilling to report the location information of the terminal; 4) the location information of the terminal is available. This embodiment may be applicable to the case where the terminal reports location information.

[0114] It can be understood that considering the cell to be a suitable cell also includes judging whether the cell is a suitable cell according to other suitable cell judgment conditions in the existing mechanism (for example, the cell is not prohibited). In addition, the above two items can be combined, that is, when 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 behavior.

[0115] In this embodiment, when the cell provides the first indication and the terminal does not have the first capability, the terminal may perform a second behavior, wherein the second behavior includes at least one of the following: 1) considering the first cell to be not a suitable cell; 2) considering the first cell to be not a candidate cell for cell selection or reselection; 3) considering the first cell to be prohibited, and additionally, considering the cell to be prohibited within a second time, for example, the first cell is prohibited within 300 seconds; 4) considering that only limited services can be obtained on the first cell. This embodiment may be applicable to the case where the terminal does not report location information.

[0116] Similarly, it can be understood that if it is considered that only limited services can be obtained on the cell, it also includes judging whether the cell is an acceptable cell according to the judging conditions of other acceptable cells in the existing mechanism.

[0117] In this embodiment, when the cell provides the first indication and the terminal is unwilling to report the location information / decides not to report the location information, the terminal performs a second behavior, and the second behavior includes at least one of the following: 1) considering the first cell to be not a suitable cell; 2) considering the first cell to be not a candidate cell for cell selection or reselection; 3) considering the first cell to be prohibited, and additionally, considering the cell to be prohibited within a second time, for example, the first cell is prohibited within 300 seconds; 4) considering that only limited services can be obtained on the first cell. This embodiment can be applicable to the case where the terminal does not report the location information.

[0118] 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 an RRC connection establishment process, an RRC connection recovery process, an RRC connection reconstruction process, a switching process and an EDT process.

[0119] The first capability is an optional capability, which does not need to be indicated to the network (Optional without indicating all).

[0120] Additionally, the first information may further include at least one of the following:

[0121] 1) First area information, used to indicate in which areas the terminal needs to report location information, the area information where the terminal is located 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 PLMNID and Cell ID); at least one second information, the second information includes carrier frequency information and at least one physical cell identifier (Physical Cell Identifier, PCI); at least one geographical location area, for example, a geographical location area can be identified by a reference point (represented by a geographical coordinate) and a distance threshold, and for example, a geographical location area can be identified by multiple geographical coordinates; at least one RAN area (identified by a RAN area ID) (including a TAC and a RAN area Code).

[0122] 2) Service-related information, used to indicate when the terminal needs to report its location information when performing certain services, including at least one of the following: emergency service (emergency), high priority access service (highPriorityAccess, related to AC 11.15), mobile terminating-Access service (Mobile Terminating-Access, mt-Access), mobile originating signaling service (Mobile Originating-Signalling, mo-Signalling), mobile originating data service (mo-Data), delay-tolerant access service (delayTolerantAccess-v1020), voice call service (mo-VoiceCall-v1280), delay-sensitive service, conversational service, streaming media service, interactive service, and background service.

[0123] Additionally, only if the terminal does not report location information according to the request of the network side within the first area, the terminal needs to perform the first behavior or the second behavior, and the first area can be agreed upon by the protocol or configured by the network side (for example, indicated in the first information); only if the service type initiated by the terminal is a certain specific service type, the terminal needs to perform the first behavior or the second behavior, and the specific service type can be agreed upon by the protocol or configured by the network side (for example, indicated in the first information)

[0124] The reported location information also includes at least one of the following: 1) reporting the location information when AS security is not activated or AS security is not used; 2) reporting the location information in 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 reestablishment process, a switching process, and an Early Data Transmission (EDT) process. This embodiment allows the network side to obtain the location information of the terminal as early as possible, which is beneficial for the network side to determine whether to allow the terminal to provide services as early as possible.

[0125] 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.

[0126] The first information may be provided through system message broadcast (for the specific signaling format, see Embodiment 5) or paging message or dedicated signaling.

[0127] Step 2: The AS of the terminal submits the first information to the NAS.

[0128] 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.

[0129] Step 3: If the terminal does not report the location information, the terminal may send a third message to the network, wherein 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 notavailable).

[0130] Additionally, the third information may further include information about a second time, where the information about the second time is used to indicate a time when the terminal is unwilling to report the location information of the terminal, or a time when the terminal decides not to report the location information of the terminal, or a time when the location information of the terminal is unavailable. The time may be a timestamp (specific time) or a time interval, etc.

[0131] 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.

[0132] 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 information of the second time and the second area information. The MAC CE is identified by a MAC PDUsubheader with LCID / ELCD, and the fixed length is 0 bits (It has a fixed size of zero bits).

[0133] It is understandable that if the network configures / requests / enables the terminal to report location information, the terminal may not report it and may still perform existing procedures, such as staying in the cell to perform RRC connection establishment procedures, uplink and downlink transmission, etc. And even if the terminal indicates that it is unwilling to report location information, the network can still request the terminal to report it.

[0134] 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.

[0135] 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 sends it to the network.

[0136] In addition, the terminal needs to send the third information only if it does not report the location information as requested by the network side within the first area, and the first area can be determined by protocol agreement or configured by the network side (for example, indicated by the first area information in the first information); the terminal needs to send the third information only if the service type initiated by the terminal is a certain specific service type, and the specific service type can be determined by protocol agreement or configured by the network side (for example, indicated by the service-related information in the first information).

[0137] Optionally, the terminal mentioned in this embodiment is an NB-IoT terminal that only supports CP CIoT EPS / 5GS Optimization.

[0138] Embodiment 2

[0139] In this embodiment, the terminal reports location information; wherein, NAS performs security processing on the location information of the terminal, provides the location information to AS, the core network decodes the location information, and the core network determines the TAC where the terminal is located, such as Figure 6 As shown, this embodiment includes the following steps:

[0140] Step 1: The terminal obtains first information, where the first information is used to instruct the terminal to report location information. The content of this step can be found in step 1 of embodiment 1, and will not be described in detail here.

[0141] Step 2: The NAS of the terminal performs security processing on 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 security processing includes at least one of encryption or integrity protection.

[0142] Additionally, NAS obtains the location information of the terminal from an upper layer (eg, APP layer).

[0143] It can be understood that the NAS layer generates NAS information including location information and performs security processing.

[0144] 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.

[0145] 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.

[0146] Step 3: The terminal sends fifth information to the network, the fifth information being carried by an RRC message, and the fifth information including the location information of the terminal securely processed by the NAS of the terminal. In this embodiment, when AS security is not used or AS security is not activated, the NAS of the terminal securely processes the location information of the terminal to improve the security of the location information of the terminal.

[0147] Optionally, the RRC message is at least one of an RRC connection establishment complete message, an RRC connection recovery complete message, an RRC connection reconstruction complete message, an RRC connection reconfiguration complete message, an RRC connection establishment request message, an RRC connection recovery request message, an RRC connection reconstruction request message, and an RRC early data request (RRCEarlyDataRequest) message. It can be understood that this embodiment can also introduce a new RRC message to carry the fifth information.

[0148] The RRC message carrying the fifth information includes at least one of the following methods:

[0149] 1) Encapsulate the fifth information into a container.

[0150] 2) The fifth information is concatenated with the RRC message.

[0151] 3) The fifth information is piggybacked into the RRC message.

[0152] Step 4: The access network receives the fifth information and sends the fifth information to the core network.

[0153] 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 the cell under the access network device, and the TAC corresponds to the service 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 LTENTN TAI Information to the core network.

[0154] If the access network provides LTE NTN TAI Information to the core network, the core network ignores TAC List in LTE NTN (see the table below).

[0155] Additionally, if the access network provides TAI (see table below) but does not provide LTE NTN TAI Information, the core network ignores TAI.

[0156]

[0157]

[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, and the area information of the terminal includes: a mapped cell identifier (MappedCell 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 based on implementation configuration.

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

[0162] Embodiment 3

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

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

[0167] It can be understood 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 acquired area information of the terminal to the core network, for example, through User Location Information IE.

[0170] It is understandable that in the existing mechanism, the access network sends the UserLocation 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 RELEASERESPONSE message, E-RAB MODIFICATION INDICATION message, UE CONTEXT RELEASECOMPLETE message, UE CONTEXT SUSPEND REQUEST message, etc.

[0171] In this embodiment, in addition to being able to trigger the access network to send the User Location Information IE to the core network during these processes, the core network also includes sending 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] Embodiment 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. After the core network performs security processing, it 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 NAS), while the location information in this embodiment is generated by AS and is RRC IE, which is only securely processed by the NAS layer. Figure 8 As shown, this embodiment includes the following steps:

[0175] Step 1: The terminal obtains first information, where the first information is used to instruct the terminal to report location information. The content of this step can be found in step 1 of embodiment 1, and will not be described in detail 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 also include a third indication for instructing NAS to perform security processing on the location information of the terminal. It is understandable that, if there is no third indication, the AS only indicates the location information of the terminal, and may also implicitly indicate that NAS needs to perform security processing on 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 the fifth information to the network, 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 reconstruction complete message, an RRC connection reconfiguration complete message, an RRC connection establishment request message, an RRC connection recovery request message, an RRC connection reconstruction request message, and an RRC early data request (RRCEarlyDataRequest) message. It can be understood that this embodiment can 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, a fourth instruction is sent to the core network to instruct the core network to perform security 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 area information of the terminal to the core network, for example, through the UserLocation Information IE.

[0186] It can be understood 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] Embodiment 5

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

[0189] If broadcast through system messages, the first information can be provided in system information used for scheduling including information related to evaluating whether the UE is allowed to access a 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 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 ways:

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

[0192]

[0193]

[0194]

[0195] 3) This field is placed in cellAccessRelatedInfo. This field is per PLMN or per SNPN (this field is specified per PLMN or per SNPN), that is, in plmn-IdentityInfo or npn-IdentityInfoList. Taking per PLMN as an example, taking the first information including only the first indication as an example, the specific signaling structure is as follows:

[0196]

[0197]
