Detailed Implementation

[0017] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0018] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0019] In the embodiments of this application, the terms "first," "second," etc., are used to distinguish similar objects, and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, and the number of objects is not limited; for example, the first object can be one or more.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] To facilitate a clearer understanding of the technical solutions of the various embodiments of this application, some technical content related to the various embodiments of this application will be introduced first.

[0022] Figure 1 This is a schematic diagram of the passive cellular network communication process, mainly including the interaction process between A-IoT devices and reading devices, such as... Figure 1 As shown, in step A, the reading device sends an A-IoT paging message to the A-IoT device; in step B, the A-IoT device that receives the paging message initiates a random access procedure, and after receiving the random access response, sends D2R data to the reading device (D2R data refers to the data sent by the A-IoT device to the reading device); in step C, after successful random access, data transmission occurs between the A-IoT device and the reading device, where C1: R2D data transmission refers to the reading device sending data to the A-IoT device, and C2: D2R data transmission refers to the A-IoT device sending data to the reading device.

[0023] Some existing technologies support positioning methods for A-IoT devices, such as A-IoT devices generating and sending positioning signals based on network configuration information. However, this method places a heavy computational burden on A-IoT devices, resulting in a cumbersome positioning process and consuming a significant amount of power. Therefore, the embodiments of this application provide a solution that reduces the computational complexity of the terminal, lowers positioning latency, and reduces power consumption by reading the device's positioning sequence and configuring it to the terminal.

[0024] Figure 2 This is one of the flowcharts illustrating the positioning method provided in the embodiments of this application. The method is applied to a terminal, such as... Figure 2 As shown, the method includes the following steps 201 and 202.

[0025] Step 201: Receive the first message sent by the reading device. The first message carries the first positioning sequence or the index of the first positioning sequence.

[0026] Step 202: Send a second message to the reading device. The second message carries the first positioning sequence or a second positioning sequence obtained based on the first positioning sequence.

[0027] Specifically, in the various embodiments of this application, the terminal may refer to user equipment (UE), active IoT device, or passive IoT device (A-IoT device), etc., without limitation.

[0028] The first message can be a paging message or any other message sent to the terminal by the reader; there are no restrictions on this. The reader can be a UE or a base station.

[0029] In this application, after receiving a location service request (a location service request for a terminal), the reading device determines a first location sequence. For example, the reading device generates the first location sequence according to the rules configured by the network or predefined by the protocol, or determines the first location sequence from the candidate location sequences. This is not limited here.

[0030] In this application, the positioning sequence refers to any sequence sent by the terminal to the reading device for the reading device to perform positioning measurement on the terminal. The specific sequence type is not limited; it can be an existing positioning sequence (or positioning signal) type, or it can be other positioning sequence types.

[0031] After the reading device determines the first location sequence, it can send the first location sequence or its index to the terminal in the first message.

[0032] In this application, the index of the positioning sequence can also be described as the identifier (ID) of the positioning sequence, and the corresponding positioning sequence can be determined based on the index or ID.

[0033] After receiving the first message, if the first message carries a first location sequence, the terminal can store the first location sequence locally; if the first message carries an index of the first location sequence, the terminal can determine the first location sequence corresponding to the index from the locally stored location sequences (each locally stored location sequence has a corresponding index) based on the index.

[0034] In some embodiments, after the terminal receives or determines the first positioning sequence, it can send the first positioning sequence to the reading device in a second message. The reading device receives the second message and performs positioning measurements on the terminal based on the first positioning sequence carried in the second message, such as measuring information such as carrier phase, received power, received angle direction, and beam direction in the second message.

[0035] In some embodiments, after receiving or determining the first positioning sequence, the terminal can obtain a second positioning sequence based on the first positioning sequence, and send the second positioning sequence to the reading device in a second message. The reading device receives the second message and performs positioning measurements on the terminal based on the second positioning sequence carried in the second message, such as measuring information such as carrier phase, received power, received angle direction, and beam direction in the second message.

[0036] The second message can be any message sent by the terminal to the reading device; there are no restrictions on its use.

[0037] The positioning method provided in this application embodiment sends a first positioning sequence or an index of the first positioning sequence to the terminal through a reading device. The terminal sends a second message to the reading device based on the first positioning sequence. The second message carries the first positioning sequence or a second positioning sequence obtained based on the first positioning sequence. Since the first positioning sequence does not need to be generated by the terminal, it can greatly reduce the computational complexity and cost of the terminal, reduce positioning latency, and reduce the power consumption of the terminal.

[0038] In some embodiments, the second positioning sequence is obtained based on the following: Generate random numbers; The first positioning sequence is modulated using random numbers, or the second positioning sequence is obtained by performing operations on random numbers and the first positioning sequence.

[0039] Specifically, the random number can be any random number, without any restrictions. For example, the random number can be a 16-bit random number (RN16) or a random number of other bit lengths.

[0040] After receiving or determining the first location sequence, the terminal can modulate the first location sequence using a generated random number to obtain a second location sequence, and then send the second location sequence to the reading device in a second message. The specific modulation method is not limited here; for example, it can be phase modulation, frequency modulation, amplitude modulation, etc., and can be flexibly selected as needed.

[0041] Alternatively, after receiving or determining the first location sequence, the terminal can perform a calculation between the generated random number and the first location sequence to obtain a second location sequence, and then send the second location sequence to the reading device in a second message. This calculation could be, for example, multiplication, addition, convolution, etc., and is not specifically limited here.

[0042] By processing the first positioning sequence with random numbers to obtain the second positioning sequence, not only can the requirements of the first positioning sequence be reduced (for example, the first positioning sequence can be a shorter sequence than the existing positioning sequence), but the correlation between the second positioning sequences sent by different terminals is also low, which is beneficial to improving the positioning accuracy of the terminal.

[0043] In some embodiments, receiving a first message sent by the reading device includes: Receive the first message sent by the reading device after the disk storage terminal.

[0044] Specifically, before the terminal receives the first message sent by the reading device, the reading device can first perform an inventory of the terminal, with the inventory and location of the terminal being performed separately.

[0045] For example, when a reading device receives a location service request, it first locates the terminal that needs to be located by checking its inventory, and then sends the first message to that terminal.

[0046] By separating inventory and positioning, the terminal positioning process does not require addressing, resulting in shorter processing time and improved positioning efficiency.

[0047] It should be noted that in some embodiments, "after the terminal is inventoried" can also be described as "after the terminal completes random access".

[0048] In some embodiments, the first message also carries one or more of the following information: (1) Terminal device identifier (ID).

[0049] The device ID is used to identify the terminal that needs to be located.

[0050] (2) Terminal Access Stratum (AS) Identifier (ID).

[0051] The AS ID is assigned to the terminal during the inventory process, so the AS ID can also be used to identify the terminal that needs to be located.

[0052] (3) Resource configuration information used to send the second message.

[0053] The terminal can determine the resource location for sending the second message based on the resource configuration information, and send the second message to the reading device at that resource location.

[0054] (4) Indication information used to indicate whether the location sequence carried by the second message is generated using random numbers.

[0055] For example, if the instruction information indicates that the location sequence carried in the second message is generated using a random number, then after the terminal receives or determines the first location sequence, it needs to process the first location sequence using a random number to obtain the second location sequence, and send the second location sequence to the reading device in the second message.

[0056] The above methods allow for more flexible positioning solutions for the terminal.

[0057] In some embodiments, the second message also carries one or more of the following information: (1) Random number.

[0058] This random number is used to distinguish different terminals and can be any random number; no restrictions are placed here.

[0059] It should be noted that when the second message carries a second location sequence, and the second location sequence is generated based on a random number, the random number carried in the second message can be the random number used to generate the second location sequence, or it can be other random numbers. This application does not limit this.

[0060] (2) Terminal device identification.

[0061] The device ID is used to identify the terminal that sends the location sequence.

[0062] (3) Terminal access layer identifier.

[0063] The AS ID is used to identify the terminal that sends the location sequence.

[0064] The above methods allow for more flexible positioning solutions for the terminal.

[0065] In some embodiments, the first message is a message that triggers random access.

[0066] Specifically, in this embodiment, the reading device can configure a first location sequence to the terminal through a random access procedure, and the reading device carries the first location sequence or the index of the first location sequence in the message that triggers random access.

[0067] In some embodiments, the message that triggers random access may be, for example, a paging message or MSG0, and the second message may be MSG1.

[0068] By performing terminal positioning measurements through a random access procedure, not only can the number of interactions between the reading and writing devices and the terminals be reduced, enabling the reading and writing devices to quickly identify the target terminals and thus reduce positioning latency, but the positioning measurement of the terminal group can also be completed quickly, improving the positioning efficiency of the terminal group.

[0069] In some embodiments, the first message also carries one or more of the following information: (1) Terminal device identifier or device group identifier.

[0070] The device ID is used to identify the terminal that needs to be located, and the device group ID is used to identify the group of terminals that need to be located.

[0071] (2) Resource configuration information used to send the second message.

[0072] The terminal can determine the resource location for sending the second message based on the resource configuration information, and send the second message to the reading device at that resource location.

[0073] (3) Indication information used to indicate whether the location sequence carried by the second message is generated using random numbers.

[0074] For example, if the instruction information indicates that the location sequence carried in the second message is generated using a random number, then after the terminal receives or determines the first location sequence, it needs to process the first location sequence using a random number to obtain the second location sequence, and send the second location sequence to the reading device in the second message.

[0075] The above methods allow for more flexible positioning solutions for the terminal.

[0076] In some embodiments, the second message also carries one or more of the following information: (1) Random number.

[0077] This random number is used to distinguish different terminals and can be any random number; no restrictions are placed here.

[0078] It should be noted that when the second message carries a second location sequence, and the second location sequence is generated based on a random number, the random number carried in the second message can be the random number used to generate the second location sequence, or it can be other random numbers. This application does not limit this.

[0079] (2) Terminal device identification.

[0080] The device ID is used to identify the terminal that sends the location sequence.

[0081] When the terminal is configured with the first location sequence through a random access procedure, the terminal may read that the device has not yet assigned an AS ID to the terminal when sending the second message. The terminal can carry the device ID in the second message for identification.

[0082] The above methods allow for more flexible positioning solutions for the terminal.

[0083] In some embodiments, the method further includes: Receive a third message sent by the reading device, the third message carrying one or more of the following information: The second message carries a random number; The terminal's access layer identifier; Instruction information used to indicate the sending of a fourth message; The third positioning sequence or the index of the third positioning sequence; Resource configuration information used to send the fourth message.

[0084] Specifically, after receiving the second message, the reading device can perform terminal location measurement based on the location sequence carried in the second message. In the case of locating multiple terminals (e.g., a group of terminals), there may be situations where two or more terminals access the system simultaneously and send the same location sequence. If the second message does not carry other information that can distinguish the terminals, or if the second message carries a random number but the random numbers of these terminals are identical, making it impossible to distinguish the terminals, the reading device can carry one or more of the following information in the third message subsequently sent to the terminal: the random number carried in the second message; the terminal's AS ID; indication information for sending the fourth message; the third location sequence or its index; and resource configuration information for sending the fourth message.

[0085] In some embodiments, the third message may be MSG2.

[0086] In some embodiments, the method further includes: A fourth message is sent to the reading device based on the third message. The fourth message carries the first positioning sequence, or the second positioning sequence, or the third positioning sequence, or the fourth positioning sequence obtained based on the third positioning sequence.

[0087] Specifically, after receiving the third message from the reading device, the terminal determines to send the location sequence to the reading device again based on the information carried in the third message. This allows the reading device to determine the unique correspondence between the received location sequence and the terminal by measuring the location sequence again, thereby solving the problem of inaccurate differentiation between multiple terminal locations. The terminal may carry the first location sequence, the second location sequence, the third location sequence, or a fourth location sequence obtained based on the third location sequence in the fourth message sent to the reading device.

[0088] The third location sequence can be carried in the third message or determined based on the index of the third location sequence carried in the third message.

[0089] In some embodiments, the method for obtaining the fourth positioning sequence based on the third positioning sequence can refer to the method for obtaining the second positioning sequence based on the first positioning sequence, and will not be described in detail here. For example: generate a random number; use the random number to modulate the third positioning sequence, or perform a calculation between the random number and the third positioning sequence to obtain the fourth positioning sequence.

[0090] In some embodiments, the fourth message may be MSG3.

[0091] In some embodiments, the fourth message also carries one or more of the following information: Terminal device identifier; The terminal's access layer identifier.

[0092] The fourth message sent by the terminal to the reading device also carries information such as the terminal's device identifier and access layer identifier, which can effectively distinguish different terminals and improve the accuracy of terminal positioning.

[0093] Figure 3 This is a second flowchart illustrating the positioning method provided in an embodiment of this application. The method is applied to a reading device, such as... Figure 3 As shown, the method includes the following steps 301, 302, 303 and 304.

[0094] Step 301: Determine the first location sequence based on the location service request.

[0095] Step 302: Send a first message to the terminal. The first message carries a first location sequence or an index of the first location sequence.

[0096] Step 303: Receive a second message sent by the terminal. The second message carries a first positioning sequence or a second positioning sequence obtained based on the first positioning sequence.

[0097] Step 304: Based on the positioning sequence carried in the second message, perform positioning measurement of the terminal.

[0098] Specifically, the first message can be a paging message or other messages sent to the terminal by the reading device; there is no limitation on this. The reading device can be a terminal or a base station.

[0099] In this application, after receiving a location service request (a location service request for a terminal), the reading device determines a first location sequence. For example, the reading device generates the first location sequence according to the rules configured by the network or predefined by the protocol, or determines the first location sequence from the candidate location sequences. This is not limited here.

[0100] In this application, the positioning sequence refers to any sequence sent by the terminal to the reading device for the reading device to perform positioning measurement on the terminal. The specific sequence type is not limited; it can be an existing positioning sequence (or positioning signal) type, or it can be other positioning sequence types.

[0101] After the reading device determines the first location sequence, it can send the first location sequence or its index to the terminal in the first message.

[0102] In this application, the index of the positioning sequence can also be described as the ID of the positioning sequence, and the corresponding positioning sequence can be determined based on the index or ID.

[0103] After receiving the first message, if the first message carries a first location sequence, the terminal can store the first location sequence locally; if the first message carries an index of the first location sequence, the terminal can determine the first location sequence corresponding to the index from the locally stored location sequences (each locally stored location sequence has a corresponding index) based on the index.

[0104] In some embodiments, after the terminal receives or determines the first positioning sequence, it can send the first positioning sequence to the reading device in a second message. The reading device receives the second message and performs positioning measurements on the terminal based on the first positioning sequence carried in the second message, such as measuring information such as carrier phase, received power, received angle direction, and beam direction in the second message.

[0105] In some embodiments, after receiving or determining the first positioning sequence, the terminal can obtain a second positioning sequence based on the first positioning sequence, and send the second positioning sequence to the reading device in a second message. The reading device receives the second message and performs positioning measurements on the terminal based on the second positioning sequence carried in the second message, such as measuring information such as carrier phase, received power, received angle direction, and beam direction in the second message.

[0106] The second message can be any message sent by the terminal to the reading device; there are no restrictions on its use.

[0107] The positioning method provided in this application embodiment sends a first positioning sequence or an index of the first positioning sequence to the terminal through a reading device. The terminal sends a second message to the reading device based on the first positioning sequence. The second message carries the first positioning sequence or a second positioning sequence obtained based on the first positioning sequence. Since the first positioning sequence does not need to be generated by the terminal, it can greatly reduce the computational complexity and cost of the terminal, reduce positioning latency, and reduce the power consumption of the terminal.

[0108] In some embodiments, sending a first message to the terminal includes: After inventorying the terminal, send the first message to the terminal.

[0109] Specifically, before the terminal receives the first message sent by the reading device, the reading device can first perform an inventory of the terminal, with the inventory and location of the terminal being performed separately.

[0110] For example, when a reading device receives a location service request, it first locates the terminal that needs to be located by checking its inventory, and then sends the first message to that terminal.

[0111] By separating inventory and positioning, the terminal positioning process does not require addressing, resulting in shorter processing time and improved positioning efficiency.

[0112] It should be noted that in some embodiments, "after the terminal is inventoried" can also be described as "after the terminal completes random access".

[0113] In some embodiments, the first message is a message that triggers random access.

[0114] Specifically, in this embodiment, the reading device can configure a first location sequence to the terminal through a random access procedure, and the reading device carries the first location sequence or the index of the first location sequence in the message that triggers random access.

[0115] In some embodiments, the message that triggers random access may be, for example, a paging message or MSG0, and the second message may be MSG1.

[0116] By performing terminal positioning measurements through a random access procedure, not only can the number of interactions between the reading and writing devices and the terminals be reduced, enabling the reading and writing devices to quickly identify the target terminals and thus reduce positioning latency, but the positioning measurement of the terminal group can also be completed quickly, improving the positioning efficiency of the terminal group.

[0117] In some embodiments, the method further includes: Send a third message to the terminal, the third message carrying one or more of the following information: The second message carries a random number; The terminal's access layer identifier; Instruction information used to indicate the sending of a fourth message; The third positioning sequence or the index of the third positioning sequence; Resource configuration information used to send the fourth message.

[0118] Specifically, after receiving the second message, the reading device can perform terminal location measurement based on the location sequence carried in the second message. In the case of locating multiple terminals (e.g., a group of terminals), there may be situations where two or more terminals access the system simultaneously and send the same location sequence. If the second message does not carry other information that can distinguish the terminals, or if the second message carries a random number but the random numbers of these terminals are identical, making it impossible to distinguish the terminals, the reading device can carry one or more of the following information in the third message subsequently sent to the terminal: the random number carried in the second message; the terminal's AS ID; indication information for sending the fourth message; the third location sequence or its index; and resource configuration information for sending the fourth message.

[0119] In some embodiments, the third message may be MSG2.

[0120] In some embodiments, the method further includes: The receiving terminal sends a fourth message, which carries a first location sequence, a second location sequence, a third location sequence, or a fourth location sequence obtained based on the third location sequence. The terminal's location is measured based on the location sequence carried in the fourth message.

[0121] Specifically, after receiving the third message from the reading device, the terminal determines to send the location sequence to the reading device again based on the information carried in the third message. This allows the reading device to determine the unique correspondence between the received location sequence and the terminal by measuring the location sequence again, thereby solving the problem of inaccurate differentiation between multiple terminal locations. The terminal may carry the first location sequence, the second location sequence, the third location sequence, or a fourth location sequence obtained based on the third location sequence in the fourth message sent to the reading device.

[0122] The third location sequence can be carried in the third message or determined based on the index of the third location sequence carried in the third message.

[0123] In some embodiments, the method for obtaining the fourth positioning sequence based on the third positioning sequence can refer to the method for obtaining the second positioning sequence based on the first positioning sequence, and will not be described in detail here. For example: generate a random number; use the random number to modulate the third positioning sequence, or perform a calculation between the random number and the third positioning sequence to obtain the fourth positioning sequence.

[0124] In some embodiments, the fourth message may be MSG3.

[0125] In some embodiments, the method further includes: The location measurement results are reported to the network device or the location requester.

[0126] Specifically, in some implementations, after the reading device performs a positioning measurement of the terminal, it can obtain the terminal's location information based on the measurement results, and then send the location information to the network device or the positioning requester.

[0127] In some implementations, after the reading device performs a location measurement on the terminal, it can send the measurement results to a network device or a location requester, which can then obtain the terminal's location information based on the measurement results, thereby reducing the computational complexity of the reading device.

[0128] The methods provided in the various embodiments of this application are based on the same technical concept, so the implementation of each method can be referred to each other, and repeated parts will not be described again.

[0129] The methods provided in the above embodiments of this application are illustrated by specific examples below.

[0130] Example 1: Figure 4 Example 1 flowchart provided for embodiments of this application, such as Figure 4 As shown, its main processes include: Step 1: The core network sends a location service request from the terminal to the reading device. The request carries information indicating that the service type is location, as well as the device ID or group ID. The core network may include A-IoT Function (AIOTF) network elements.

[0131] Step 2: Read the paging message sent by the device to the terminal to trigger random access. This random access can be either contention-based random access (CBRA) or contention-free random access (CFRA).

[0132] Step 3: The terminal sends MSG1 to the reading device.

[0133] Step 4: Read the device sending MSG2 to the terminal.

[0134] Step 5: The terminal sends MSG3 to the reading device, carrying the terminal's device ID.

[0135] Step 6: Read the terminal ID that the device has sent to the core network after completing random access.

[0136] It should be noted that steps 1 to 6 are the traditional terminal communication paging process. After the reading device finds the target device (or target terminal, i.e. the terminal that needs to be located), it sends the ID of the target device back to the core network.

[0137] Step 7: The core network sends a confirmation message for the location service to the reading device, and the message carries the target device ID.

[0138] Step 8: Read the first message sent by the device to the target device, which carries one or a combination of the following information: The target device's device ID; AS ID of the target device; The first positioning sequence or the index of the first positioning sequence; Resource configuration information used to send the second message; This is used to indicate whether the location sequence carried in the second message was generated using random numbers.

[0139] Step 9: After receiving the first message sent by the reading device, the target device assumes that it is being scheduled or notified and needs to send a location sequence.

[0140] The target device can determine the resource location for sending the second message based on the resource configuration information carried in the first message in step 8, and send the second message at that resource location. The second message carries one or a combination of the following information: Random numbers; The target device's device ID; AS ID of the target device; The first positioning sequence or the second positioning sequence.

[0141] Step 10: The reading device receives the second message at the resource location where the second message is sent, and measures information such as the carrier phase, received power, received angle direction, and beam direction of the second message.

[0142] Step 11: Method 1: The reading device obtains the target device's location information relative to itself or the target device's absolute location information based on the measurement results, and sends the target device's device ID and corresponding location information to the core network.

[0143] Method 2: The reading device provides one or a combination of the following results to the core network: The measurement results include information such as the carrier phase, received power, received angle direction, beam direction, and beam sequence number of the second message; The identifier corresponding to the location service request; Target device ID or device group ID; Read the device's geographic location information and corresponding timestamp.

[0144] The core network obtains the position information of the target device relative to the reading device or the absolute position information of the target device based on the measurement results.

[0145] Step 11: After obtaining the location information of the target device, the core network sends a service termination instruction to the reading device.

[0146] Step 12: Read the device's service completion information and send it to the target device to complete this location service.

[0147] It should be noted that if the reading device fails to receive the second message at the resource location where the second message was sent, and fails to measure the location of the target device, the reading device can reschedule and resend the first message from step 8. The target device will then respond to the first message in step 8 again and resend the second message from step 9. The reading device can determine the number of rescheduling attempts based on pre-configured or core network-provided positioning service indicators (such as positioning latency and / or positioning attempts). If the number of rescheduling attempts exceeds the limit set by the aforementioned positioning service indicators, the reading device will report a positioning failure to the core network.

[0148] Example 2: Figure 5 Example 2 flowchart provided for embodiments of this application, such as Figure 5 As shown, its main processes include: Step 1: The core network initiates a location request for a specific terminal or a group of terminals. The core network sends a location service request for the terminal to the reading device. The request carries information indicating that the service type is location, as well as the device ID or group ID.

[0149] Step 2: Read the first message sent by the device to the target device, such as a paging message, which carries one or a combination of the following information: The device ID of the target device or the group ID of the target device group; The first positioning sequence or the index of the first positioning sequence; Resource configuration information used to send the second message; This is used to indicate whether the location sequence carried in the second message was generated using random numbers.

[0150] Step 3: After receiving the first message sent by the reading device, the target device assumes that it is being scheduled or notified and needs to send a location sequence.

[0151] The target device can determine the resource location for sending the second message based on the resource configuration information carried in the first message in step 2, and send the second message (MSG1) at that resource location. The second message carries one or a combination of the following information: Random numbers; The target device's device ID; The first positioning sequence or the second positioning sequence.

[0152] Step 4: The device receives the second message at the resource location where the second message was sent, and measures information such as the carrier phase, received power, received angle direction, and beam direction of the second message. The AS ID assigned to the terminal is matched and stored with the terminal's random number and the measurement results to calculate the terminal's location information.

[0153] Step 5: When locating multiple terminals (e.g., a group of terminals), there may be situations where two or more terminals access the system simultaneously and send the same location sequence. If the second message does not carry other information that can distinguish the terminals, or if the second message carries a random number but the random numbers of these terminals are the same, making it impossible to distinguish the terminals, the reading device can carry one or a combination of the following information in the third message (MSG2) sent to the target device: MSG1 carries a random number; The AS ID assigned to the target device in step 4; Instruction information used to indicate the sending of a fourth message; The third positioning sequence or the index of the third positioning sequence; Resource configuration information used to send the fourth message.

[0154] Step 6: After receiving the third message, the target device retrieves the previously generated sequence or regenerates the fourth location sequence according to the instructions in Step 5, and sends the fourth message (MSG3) at the resource location where the fourth message was sent. The fourth message carries the first location sequence, or the second location sequence, or the third location sequence, or the fourth location sequence obtained based on the third location sequence, and may also carry the device ID or AS ID of the device.

[0155] Step 7: The reading device receives the fourth message at the resource location where the fourth message was sent, and measures information such as the carrier phase, received power, received angle direction, and beam direction of the fourth message.

[0156] Step 8: Method 1: The reading device obtains the target device's location information relative to itself or the target device's absolute location information based on the measurement results, and sends the target device's device ID and corresponding location information to the core network.

[0157] Method 2: The reading device provides one or a combination of the following results to the core network: The measurement results include information such as carrier phase, received power, received angle direction, beam direction, and beam sequence number of the fourth message; The identifier corresponding to the location service request; Target device ID or device group ID; Read the device's geographic location information and corresponding timestamp.

[0158] The core network obtains the position information of the target device relative to the reading device or the absolute position information of the target device based on the measurement results.

[0159] Step 9: After obtaining the location information of the target device, the core network sends a service termination instruction to the reading device.

[0160] Step 10: Read the service completion information sent by the device to the target device to complete this location service.

[0161] It should be noted that the random number received by the reading device in step 3 may be the same as the random number sent by another terminal, meaning there is a possibility that the second message measured by the reading device corresponds to both devices. The reading device can measure the positioning sequence again in step 7 after resolving the conflict to clarify the unique correspondence between the positioning sequence sent by the terminal and that terminal. This resolves the inter-device conflict problem in terminal group positioning, and the group positioning of terminals can be quickly completed by resolving random access conflicts.
