Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a method, device and equipment for obtaining positioning data. Background Art

[0002] As a data analysis network element, the Network Data Analytics Function (NWDAF) can provide data statistics and analysis for 3GPP internal network elements or third parties. With the help of NWDAF's analysis function, accurate positioning prediction can be achieved. However, in order to achieve positioning prediction, NWDAF needs to use a large amount of positioning data (for example, measurement information reported by user equipment) in advance to train the positioning model.

[0003] In the related art, NWDAF can directly obtain the positioning result from the Location Management Function (LMF) through the Gateway Mobile Location Center (GMLC). The positioning result is the positioning related information (e.g., positioning method, positioning result estimation) calculated by the LMF, not the original positioning data reported by the user device (e.g., cell measurement information, etc.). Therefore, the related art does not provide a solution for how NWDAF obtains the original positioning data reported by the user device. Summary of the invention

[0158] To facilitate understanding of the technical solutions provided by the present application, the main technical concepts involved in the embodiments of the present application are briefly described below.

[0159] NWDAF obtains positioning data:

[0160] In the current protocol architecture, in the research before Rel-18, NWDAF can obtain coarse-grained location information, that is, information at the TA / cell level, such as cell ID, through the Access and Mobility Management Function (AMF). In the research of Rel-18, NWDAF can interact with the Live Communications Server (LCS) architecture through the GMLC interface to obtain the user equipment (UE) location information and content related to positioning accuracy. Specifically, the information obtained is the information that can be provided in the current Ngmlc interface service. In other words, NWDAF directly obtains positioning information from LMF through GMLC. The positioning information is positioning related information calculated by LMF, not the original positioning data reported by UE. The current relevant technology does not provide the original positioning data reported by UE to NWDAF or other network elements.

[0161] User plane positioning connection between UE and LMF:

[0162] The TS23.273 protocol specifies the process of establishing a user plane connection from the UE to the LMF and transmitting LPP messages or LCS-SS messages through the user plane. The UE can initiate the establishment of the user plane (i.e., UE-initiated user plane connection), and the LMF can also initiate the establishment of the user plane (i.e., LMF-initiated User Plane Connection). In the process of establishing the user plane, the first step is that the UE establishes a protocol data unit (PDU) session based on the UE route selection policy (UE Route Selection Policy, URSP), and then based on the PDU session, the second step is that the UE uses the received user plane information (e.g., LMF address) to establish a connection connection; the third step is that on top of the connection, LPP messages or LCS-SS messages (e.g., event report) can be transmitted between the UE and the LMF. For example, Figure 2 The process of establishing the user plane initiated by LMF in the TS23.273 protocol.

[0163] User plane positioning connection between UE and LCS client:

[0164] R18 supports the transmission of event reports from UE to location services client (LCS client) and application function (AF) through the user plane. The specific process is as follows:

[0165] Step 1: The LCS client carries the indication information in the request: the user plane performs event reporting, optionally carries the LCSclient / AF address, and the security information of the connection. After the GMLC verifies the target UE and the LCS client / AF, it sends the deferred MT-LR request to the UE step by step;

[0166] Step 2: UE establishes a Transmission Control Protocol / Internet Protocol (TCP / IP) connection to the LCS client;

[0167] Step 3: If the UE cannot obtain the location estimate itself, it uses the control plane to let the network calculate and pass it to the LCS client / AF. If the location estimate can be obtained, it is directly transmitted using the user plane.

[0168] Step 4: The event report and confirmation reply (Acknowledge, ACK) are transmitted through the user plane;

[0169] Step 5: Send a cumulative event report through the control plane. The control plane is still active and may carry statistical information of event reports, request LPP assistance information, etc.

[0170] Step 6: Release the connection after the transfer is complete.

[0171] Control plane connection between UE and NWDAF:

[0172] NWDAF can initiate a deferred 5GC-MT-LR request for UE location information and perform event reporting to the LCS control plane architecture by using the GMLC interface. When subsequent events are triggered, the UE can report the event report to NWDAF through the control plane, for example, the positioning method, positioning result estimation, rate estimation and other information.

[0173] In summary, the relevant technology is to let NWDAF collect UE positioning-related data through the control plane, but NWDAF does not know the original positioning data reported by UE, such as the measurement results of the serving cell and the neighboring cell. In addition, UE transmits the event report to NWDAF through the control plane, but there is no regulation on how to transmit it to NWDAF through the control plane. UE to LMF / LCS client / AF can transmit LPP messages and LCS-SS messages through the user plane to achieve high-frequency and large data packet transmission, but whether UE can use the user plane to transmit information to NWDAF is not mentioned.

[0174] Therefore, the embodiment of the present application provides a method for obtaining positioning data, wherein a first communication device (such as NWDAF) sends a first request to request a second communication device (such as LMF) to collect the original positioning data of a target user device through a user plane, and then the second communication device sends the original positioning data to the first communication device after receiving the original positioning data reported by the target user device through the user plane. Because the original positioning data is collected through the user plane, and the user plane supports the transmission of high frequency and large data packets, the original positioning data can be quickly obtained.

[0183] First request: A request sent by a first communication device (such as NWDAF) to collect the location data of the target user device through the user plane. When the first communication device interacts with the second communication device, the first communication device can send the first request directly to the second communication device; when the first communication device interacts with the third communication device, the first communication device sends the first request to the second communication device through the third communication device.

[0184] Second request: A request generated by a second communication device (such as LMF) and sent to a target user device according to the first request.

The second request can be sent by the second communication device to the target user device through the control plane, or it can be sent by the second communication device to the target user device through the user plane. After receiving the second request, the target user device collects positioning data that meets the data type according to the second request, and reports the positioning data to the second communication device through the user plane. Positioning data refers to positioning data that meets the data type, which can be understood as the target user device providing corresponding positioning data according to the data type provided in the second request, or it can be understood as when the second request does not carry a data type, the target user device provides positioning data according to a local policy, a default policy, or a policy negotiated and specified by the user device and the network side device.

[0185] First response: a response received by the first communication device after sending the first request, used to indicate acceptance or rejection of collecting the positioning data of the target terminal through the user plane. The first response is generated by the second communication device or the third communication device (such as GMLC).

[0186] In combination with the unified description of each term above, in a first aspect of the embodiment of the present application, a method for obtaining positioning data is provided, which is applied to a first communication device, see Figure 3 FIG. 1 is a flowchart of a method for obtaining positioning data provided by an embodiment of the present application. The method may include the following steps:

[0187] Step S310: The first communication device sends a first request, where the first request is used to request to collect positioning data of a target user equipment through a user plane;

[0188] Step S320: the first communication device receives the positioning data sent by the second communication device, where the positioning data is the positioning data collected by the target user equipment and reported to the second communication device through the user interface;

[0189] The first request includes at least one of the following:

[0190] Item A-1: ​​data type data type, used to indicate the type of positioning data that needs to be reported by the target user equipment;

[0191] Item A-2: terminal device identification, used to indicate the identification of the target user device;

[0192] Item A-3: User plane collection indication, used to indicate that the first communication device needs to collect event reporting or positioning data of the target user equipment through the user plane;

[0193] Item A-4: address of the first communication device, used to indicate the address of the first communication device;

[0194] Item A-5: task ID, used to indicate the collection task associated with the positioning data;

[0195] Item A-6: Security profile, used to indicate relevant information to ensure the security of interaction;

[0196] Item A-7: reporting time, used to indicate the reporting time period of the positioning data;

[0197] Item A-8: reporting mode, parameter information for indicating the reporting mode of the positioning data;

[0198] Item A-9: Data collection time, used to indicate the collection period of the positioning data;

[0199] Item A-10: Data trigger type, used to indicate the trigger method for generating the positioning data.

[0200] In an embodiment of the present application, a first communication device sends a first request through a control plane to request to collect positioning data of a target user device through a user plane. Among them, positioning data refers to positioning data collected by the target user device according to the first request, and positioning data can be positioning-related measurement data, for example, a serving cell measurement result, a neighboring cell measurement result. In a specific implementation, the first communication device directly or indirectly sends the first request to the second communication device, so that the second communication device (referring to a communication device that supports user plane positioning) collects positioning data of the target user device through the user plane after receiving the first request. Specifically, when the first communication device interacts with the second communication device, the first communication device directly sends the first request to the second communication device, and when the first communication device interacts with other communication devices (such as a third communication device), the first communication device sends the first request to the second communication device through other communication devices. After the second communication device receives the first request, it triggers the target user device to collect and report the positioning data requested in the first request to the second communication device through the user plane, and then the second communication device sends the positioning data reported by the target user device to the first communication device. Since the positioning data collected by the target user equipment has the characteristics of high frequency and large data packets, and the user plane supports the transmission of high frequency and large data packets, the original positioning data can be quickly collected through the user plane, wherein the original positioning data refers to the positioning data collected by the target user equipment without being processed by other network elements. In this way, the first communication device can quickly collect the original positioning data reported by the target user equipment through the user plane.

[0201] In one embodiment, when no user plane connection is established in advance between the second communication device and the target user equipment, after receiving the first request, the second communication device triggers the establishment of a user plane connection with the target user equipment through the control plane, and then the target user equipment collects and reports the positioning data requested in the first request to the second communication device through the user plane. In another embodiment, when a user plane connection is established between the second communication device and the target user equipment, after receiving the first request, the second communication device directly triggers the target user equipment to collect and report the positioning data requested in the first request to the second communication device through the user plane.

[0202] In order to realize the rapid collection of positioning data through the user plane, at least one of the above-mentioned items A-1 to A-10 may be included in the first request. Specifically, the data type data type of item A-1 is used to indicate the type of positioning data that needs to be reported by the target user equipment. The data types that need to be reported include: measurement data (including service cell measurement results, neighboring cell measurement results), intermediate feature data (including TOA, path phase, etc.), measurement configuration information, reference cell information, neighboring cell information, RSTD search time window, measurement data (including CIR / PDP / DP (RSRP / RSRPP / RSTD) and other data. When the target user equipment reports the positioning data, it reports according to the data type indicated in the first request. Measurement data refers to the data used for measurement during the positioning process. UE, LMF and other devices can calculate based on the measurement data to obtain location information data. Intermediate feature data refers to the data generated by UE / RAN and other devices in the process of processing measurement data, which may be generated by processing the measurement data based on certain algorithms or models. Among them, RSRP is the abbreviation of Reference Signal Received Power. It is a measure of the strength of the wireless signal received in an LTE network.

[0203] RSRPP refers to PathPRSR, that is, the reference signal received power (Reference Signal Received Power Path) on one of the paths in a multipath situation.

[0204] RSTD is the abbreviation of Reference Signal Time Difference, also known as TA (Timing Advance). It is another important wireless parameter in LTE networks and is used to measure the delay difference between different base stations.

[0205] CIR is the abbreviation of Channel Impulse Response. It is an important parameter used to describe wireless channels and is used to indicate the response of the channel to a specific frequency.

[0206] PDP refers to Power Delay Profile. CIR refers to the combination of attenuation, delay, and phase response in the transmission path of the signal from the transmitter to the receiver, while PDP is the statistical data of CIR, which describes the signal strength under different delays.

[0207] TOA is the abbreviation of Time of Arrival. It is used to measure the propagation time of a signal from a transmitter to a receiver, thereby calculating the distance between the transmitter and the receiver.

[0208] The terminal device identification in item A-2 is used to indicate the identification of the target user device. The terminal identification can be identification information of a user device or identification information of a group of user devices.

[0209] Item A-3 User plane collection indication is used to indicate that the first communication device needs to collect event reports or positioning data of the target user equipment through the user plane. That is, when item A-3 is included in the first request, it indicates that the first communication device needs to collect positioning data reported by the target user equipment through the user plane.

[0210] In item A-4, the address of the first communication device is used to indicate the address of the first communication device. In one embodiment, the address of the first communication device is used to indicate the IP address of the first communication device. In order to avoid leakage of the address of the first communication device, the first communication device needs to support distributed denial of service (DDOS). For example, the target user device is required not to send frequently.

[0211] A-5 task ID is used to indicate the collection task associated with the positioning data. That is, the task ID is used by the first communication device to verify and distinguish different collection tasks, and the task ID can be expressed as an analysis ID or a model ID. Specifically, since the first communication device can receive a variety of different positioning data at the same time, after the first communication device receives the positioning data sent by the first communication device, it is necessary to distinguish whether the received positioning data is used for training or reasoning of which analysis function, so a task ID is required to distinguish.

[0212] A-6 Security profile is used to indicate relevant information to ensure the security of interaction, such as security verification algorithms, keys, etc.

[0213] The reporting time in item A-7 is used to indicate the reporting time period of the positioning data. For example, it is used to indicate the time period for current reporting or future reporting. When indicating the time period for future reporting, the reporting time also includes the start time, the end time, the periodic repetition information, the start time of the periodic repetition, and the end time of the periodic repetition. For example, the start time is 10:00, the end time is 20:00, the periodic repetition information is repeated every day, the start time of the periodic repetition is October 1, 2023, and the end time of the periodic repetition is October 6, 2023. Through this time setting, the target user device can be required to report its own positioning data between 10:00-20:00 every day from October 1 to October 6 in the future.

[0214] The reporting method in item A-8 is used to indicate the parameter information of the reporting method of the positioning data. Specifically, the reporting method includes three methods: one-time reporting, periodic reporting, and batch reporting. When the reporting method is periodic reporting, it also carries parameters such as the minimum time interval, the maximum time interval, and the number of reports. In the specific implementation, if it is a periodic report, the time interval between the two reports of the target user equipment through the data plane needs to be greater than the minimum time interval. After the maximum time interval is reached, it is necessary to report the positioning data once through the data plane. If the maximum number of reports is met, there is no need to report again. These parameters are optional. If it is a batch report, for example, the target user equipment reports to the first communication device at one time after accumulating 10 or 20 times. The amount of data is large, and it is more reasonable to report through the data plane.

[0215] Item A-9, data collection time, is used to indicate the collection time period of the positioning data, that is, to indicate the time period of positioning information required. The data collection time includes a start time, an end time, a periodic repetition mode, a periodic repetition start time, and a periodic repetition end time.

[0216] The trigger type of data in item A-10 is used to indicate the triggering method for generating the positioning data. Specifically, the triggering types of data include: passive positioning data, active positioning data, passive positioning data and active positioning data. Among them, passive positioning data means that the positioning data is generated by a positioning process triggered by the network, and active positioning data means that the positioning data is generated by a positioning process triggered by the terminal. The positioning data (deferred 5GC MT-LR) generated by event triggering can be understood as active positioning data. For example, MO-LR is a positioning actively triggered by UE, and MT-LR is a positioning passively triggered by UE.

[0217] In specific implementation, if the first communication device indicates active positioning data in the first request, the positioning data generated under the MO-LR needs to be reported, and then the requirements of the data reporting time and periodic reporting indication information are superimposed to send it to the first communication device. If the first communication device indicates passive positioning data in the first request, the data generated under the MT-LR needs to be reported, and then the requirements of the data reporting time and periodic reporting indication information are superimposed to send it to the first communication device. If the first communication device indicates passive positioning data and active positioning data in the first request, the positioning data generated in both active and passive situations need to be reported. In one embodiment, the positioning request (for example: MT-LR) may not be initiated by the first communication device, but may be any commercial positioning request or delayed commercial positioning request initiated by an LCS client, and the positioning data generated by such a request is also within the reporting range.

[0218] In an embodiment of the present application, the positioning data received by the first communication device includes, in addition to the data corresponding to the data type data type, information such as the sending task identifier task ID and the terminal device identifier in the first request. After the first communication device receives the positioning data, it can determine the analysis function corresponding to the positioning data based on the task identifier task ID and the terminal device identifier carried by the positioning data, and perform data analysis, result prediction, model training and other processing on the positioning data based on the analysis function. Furthermore, the method implemented based on the present application solves the problem of how the network elements of 5GC such as the first communication device (such as NWDAF) can quickly collect the positioning data of the target user device through the user plane by establishing a user plane connection with the assistance of the second communication device (such as LMF), so as to assist the NWDAF or 5GC network elements to achieve functional enhancement, for example, to execute AI positioning functions (such as prediction of positioning accuracy, prediction of positioning methods, etc.).

[0219] In a specific implementation manner, the first communication device sends a first request, including:

[0220] The first communication device queries a second communication device that supports obtaining positioning data through a user plane, and directly sends the first request to the second communication device; or the first communication device sends the first request to a third communication device to trigger the third communication device to determine a second communication device that supports obtaining positioning data through a user plane, and then send the first request to the second communication device.

[0221] In an embodiment of the present application, there are two situations in which the first communication device and the second communication device are directly connected and indirectly connected through a third communication device. When the first communication device is directly connected to the second communication device, that is, the first communication device interacts with the second communication device, the first communication device queries the second communication device that supports obtaining positioning data through the user plane through the Network Repository Function (NRF), and then sends the first request to the second communication device. When the first communication device is indirectly connected to the second communication device through a third communication device, that is, the first communication device interacts with the third communication device, the first communication device sends the first request to the second communication device through the third communication device.

[0222] In one embodiment, when the first communication device interacts with the third communication device, in order to send the first request to the second communication device, the third communication device performs the following steps after receiving the first request:

[0223] The third communication device sends the first request to the fourth communication device to trigger the fourth communication device to determine a second communication device that supports obtaining positioning data through a user plane, and then send the first request to the second communication device. Specifically, the fourth communication device determines the second communication device that supports obtaining positioning data through a user plane according to a user plane collection indication User plane collection indication in the first request.

[0224] In a specific implementation manner, after the first communication device sends the first request, the following steps are further included:

[0225] The first communication device receives a first response, where the first response is used to indicate acceptance or rejection of collecting the positioning data of the target terminal through a user plane.

[0226] In the embodiment of the present application, after the first communication device sends a first request to collect the location data of the target user device through the user plane, in order to ensure the security of the location data collection and the normal reporting of the location data, the second communication device and the third communication device will verify the authority or qualification related to the first request after receiving the first request, and reply a first response to the first communication device to inform the first communication device to accept or refuse to collect the location data of the target terminal through the user plane.

[0227] In a specific implementation, if the first response is generated by the third communication device, the third communication device directly sends the first response to the first communication device so that the first communication device receives the first response. If the first response is generated by the second communication device, the second communication device sends the first response to the first communication device, including: when the second communication device is indirectly connected to the second communication device, the second communication device sends the first response to the first communication device in sequence through the fourth communication device and the third communication device; or when the second communication device is directly connected to the first communication device, the second communication device sends the first response directly to the first communication device.

[0228] In one implementation, after the third communication device receives the first request, the following steps are performed:

[0229] Step B1: the third communication device verifies whether the first communication device is authorized to obtain positioning data through the user plane, and verifies whether the target user equipment is authorized to report positioning data through the user plane;

[0230] Step B2: The third communication device generates a first response based on the verification result and sends it to the first communication device, where the first response is used to indicate acceptance or refusal to collect the positioning data of the target terminal through the user plane.

[0231] Specifically, when the first response is used to indicate a refusal to collect the positioning data of the target terminal through the user plane, the first response carries a first rejection reason, and the first rejection reason is any one of the following:

[0232] Item C-1: The target user equipment is not authorized to report positioning data via the user interface;

[0233] Item C-2: The first communication device is not authorized to obtain positioning data through the user plane;

[0234] Item C-3: The target user equipment is not authorized to report positioning data through the user plane, and the first communication device is not authorized to obtain positioning data through the user plane.

[0235] In the embodiment of the present application, when the first communication device interacts with the third communication device, step B1 is executed after the third communication device receives the first request. Specifically, the third communication device verifies the first communication device and the target user device by searching for the contract data of the first communication device and the target user device through Unified Data Management (UDM). If the corresponding contract data can be found, it means that the device is authorized.

[0236] In a specific implementation, when the third communication device verifies that the target user device is not authorized to report the positioning data through the user plane, the execution step B2 is triggered to generate a first response carrying a rejection indication and a first rejection reason (i.e., item C-1) to indicate that the user plane is rejected to collect the positioning data of the target terminal. When the third communication device verifies that the first communication device is not authorized to obtain the positioning data through the user plane, the execution step B2 is triggered to generate a first response carrying a rejection indication and a first rejection reason (i.e., item C-2) to indicate that the user plane is rejected to collect the positioning data of the target terminal. When the third communication device verifies that the target user device is not authorized to report the positioning data through the user plane, and the first communication device is not authorized to obtain the positioning data through the user plane, the execution step B2 is triggered to generate a first response carrying a rejection indication and a first rejection reason (i.e., item C-3) to indicate that the user plane is rejected to collect the positioning data of the target terminal.

[0237] It should be noted that, when the target user equipment authorizes reporting positioning data through the user plane and the first communication device authorizes obtaining positioning data through the user plane, the third communication device does not perform step B2. At this time, the third communication device sends the received first request to the second communication device through the fourth communication device.

[0238] In one embodiment, when a user plane connection is not established in advance between the second communication device and the target user equipment, after receiving the first request, the second communication device triggers establishment of a user plane connection with the target user equipment through the control plane, so that the target user equipment collects and reports the positioning data requested in the first request to the second communication device through the user plane.

[0239] Specifically, after the second communication device receives the first request, the following steps are performed:

[0240] Step D1: The second communication device determines whether to use the user plane to collect positioning data;

[0241] Step D2: When it is determined that the user plane is used to collect positioning data, the second communication device sends user plane establishment information to the target user equipment;

[0242] Step D3: The second communication device receives the user plane establishment reply information sent by the target user equipment, where the user plane establishment reply information is used to indicate whether the target user equipment accepts reporting of positioning data through the user plane;

[0243] Step D4: The second communication device generates a first response and sends it to the first communication device, where the first response is used to indicate acceptance or rejection of collecting the positioning data of the target terminal through the user plane.

[0244] Specifically, when the first response is used to indicate a refusal to collect the positioning data of the target terminal through the user plane, the first response carries a second rejection reason, and the second rejection reason is any one of the following:

[0245] E-1: No user plane transmission resources are available;

[0246] Item E-2: The load of the second communication device exceeds a preset threshold;

[0247] Item E-3: The target user equipment refuses to report positioning data via the user plane.

[0248] In the embodiment of the present application, after receiving the first request, the second communication device first executes step D1, that is, the second communication device determines whether to use the user plane to collect the positioning data of the target terminal according to the service situation and the load situation. If it is found that there are no available user plane transmission resources or the load of the second communication device exceeds the preset threshold (that is, the load is too large), it is determined not to use the user plane to collect the positioning data, and the execution of step D4 is triggered to generate a first response. The first response generated at this time carries a rejection indication and a second rejection reason (item E-1 or item E-2) to indicate that the positioning data of the target terminal is rejected to be collected through the user plane.

[0249] If the second communication device determines to use the user plane to collect positioning data, the second communication device executes step D2 to send user plane establishment information to the target user equipment. Specifically, the user plane establishment information may include: the address address of the first communication device, the data type data type, the task identifier task ID and the security information Secure profile. In the specific implementation, the second communication device sends the user plane establishment information to the fourth communication device, and then the fourth communication device encapsulates the user plane establishment information in a container in the DL NAS TRANSPORT message and sends it to the target user equipment. Among them, the DL NAS TRANSPORT message may be an existing privacy verification message (for example, LCS-SS message privacynotification, used to notify the target user equipment whether private information can be disclosed to the outside). It should be noted that the security information Secure profile in the user plane establishment information may not be the security information Secureprofile sent in the first request, but the security information Secure profile determined by the second communication device itself.

[0250] After the target user equipment receives the user plane establishment information sent by the second communication device, the target user equipment sends a user plane establishment reply information to the second communication device, triggering the execution of step D3 in which the second communication device receives the user plane establishment reply information sent by the target user equipment. In specific implementation, the user plane establishment reply information sent by the target user equipment can be an IE or a message, and the user plane establishment reply information is encapsulated in a container in a UL NAS transport message and sent to the fourth communication device, and the fourth communication device then forwards the container to the second communication device.

[0251] If the user plane establishes a reply message that the target user device accepts reporting positioning data through the user plane, then the step D4 is triggered to generate a first response carrying an acceptance indication to indicate acceptance of collecting positioning data of the target terminal through the user plane. The acceptance indication can be explicit or implicit (for example, indicated by the message type, if the message is an accept message, it indicates acceptance, and there is no specific bit to clearly indicate). If the user plane establishes a reply message that the target user device does not accept reporting positioning data through the user plane, then the step D4 is triggered to generate a first response carrying a rejection indication and a second rejection reason (i.e., item E-3) to indicate rejection of collecting positioning data of the target terminal through the user plane.

[0252] In summary, the first communication device can receive the first response in the following three situations. (1) When the first communication device interacts with the third communication device, after the third communication device receives the first request, it verifies that the first communication device is not authorized to obtain positioning data through the user plane, or the target user device is not authorized to report positioning data through the user plane, or the target user device is not authorized to report positioning data through the user plane and the first communication device is not authorized to obtain positioning data through the user plane, the third communication device will generate a first response and send it to the first communication device, and the first response carries the first rejection reason (i.e., any one of items C-1 to C-3). (2) After the second communication device receives the first request, if the second communication device determines not to use the user plane to collect positioning data, the second communication device generates a first response and sends it to the first communication device, and the first response carries the second rejection reason (i.e., item E-1 or item E-2). (3) After the second communication device sends user plane establishment information to the target user device, the second communication device generates a first response based on the user plane establishment reply information sent by the target user device and sends it to the first communication device. If the user plane establishment reply information is that the target user device accepts reporting positioning data through the user plane, the generated first response is used to indicate acceptance of collecting positioning data of the target terminal through the user plane; if the user plane establishment reply information is that the target user device refuses to report positioning data through the user plane, the generated first response is used to indicate refusal to collect positioning data of the target terminal through the user plane, and the second rejection reason carried in the first response is the rejection reason of item E-1.

[0253] In a specific implementation manner, in order to obtain the positioning data, after the second communication device receives the first request sent by the first communication device, the second communication device further performs the following steps:

[0254] Step F1: the second communication device generates a second request according to the first request and sends the second request to the target user equipment, where the second request at least includes a data type data type, where the data type is used to indicate a type of positioning data that needs to be reported by the target user equipment;

[0255] Step F2: the second communication device receives the positioning data reported by the target user equipment through the user plane;

[0256] Step F3: The second communication device sends the received positioning data to the first communication device.

[0257] In an embodiment of the present application, positioning data refers to positioning data that satisfies a data type. The second communication device allows the target user device to collect positioning data through a second request that includes at least the data type. After receiving the second request, the target user device collects positioning data that satisfies the data type according to the second request, and reports the positioning data to the second communication device through the user.

[0258] In one implementation, the second request includes the same content as the first request. In one embodiment, the second request includes at least one of the following:

[0259] Item A-1: ​​data type data type, used to indicate the type of positioning data that needs to be reported by the target user equipment;

[0260] Item A-2: terminal device identification, used to indicate the identification of the target user device;

[0261] Item A-3: User plane collection indication, used to indicate that the first communication device needs to collect event reporting or positioning data of the target user equipment through the user plane;

[0262] Item A-4: address of the first communication device, used to indicate the address of the first communication device;

[0263] Item A-5: task ID, used to indicate the collection task associated with the positioning data;

[0264] Item A-6: Security profile, used to indicate relevant information to ensure the security of interaction;

[0265] Item A-7: reporting time, used to indicate the reporting time period of the positioning data;

[0266] Item A-8: reporting mode, parameter information for indicating the reporting mode of the positioning data;

[0267] Item A-9: Data collection time, used to indicate the collection period of the positioning data;

[0268] Item A-10: Data trigger type, used to indicate the trigger method for generating the positioning data.

[0269] Specifically, in addition to the data type data type, the second request may also include: task identifier task ID, data trigger type, reporting time and reporting method and other parameters, so that the target user device can locate the data according to the reporting method and reporting time; and the target user device can report the task identifier and the positioning data together, so that after the first device receives the positioning data, it can distinguish the positioning data according to the task identifier and correspond to the corresponding analysis task or positioning model.

[0270] In one embodiment, the positioning data refers to the positioning data that satisfies the data type, which can be understood as the target user device providing corresponding positioning data according to the data type provided in the second request. It can also be understood as when the second request does not carry the data type, the target user device provides the positioning data according to the local policy, the default policy or the policy negotiated and specified by the user device and the network side device.

[0271] In one implementation, the second communication device sends the second request to the target user equipment, including: the second communication device sends the second request to the target user equipment through the control plane; or the second communication device sends the second request to the target user equipment through the user plane.

[0272] Specifically, the second communication device sending the second request to the target user equipment through the control plane means that: when the second communication device establishes information to the user plane through the control plane, it can also send the second request information to the target user equipment, so that the target terminal reports the positioning data through the user plane. The second communication device sending the second request to the target user equipment through the user plane means that: after the second communication device establishes a user plane connection with the target user equipment, it can send the second information to the target user equipment through the user plane, so that the target terminal reports the positioning data through the user plane.

[0273] In specific implementation, if there is a user plane connection between the second communication device and the target user device, the second communication device and the target user device directly use the user plane to interact. If there is no user plane connection between the second communication device and the target user device, a user plane connection is established. The reporting of positioning data by the target user device through the user plane is based on the PDU session. If the target user device does not establish a PDU session for transmitting positioning data, a PDU establishment process is initiated to establish a PDU session for user plane positioning connection. The target user device can use the DNN+Slice information configured by URSP to create a new one.

[0274] In the embodiment of the present application, after receiving the first request, the second communication device generates a second request and sends it to the target user device, and then the target user device collects positioning data according to the second request and reports the positioning data to the second communication device, and then the second communication device sends the positioning data to the first communication device, so that the first communication device can use the second communication device to quickly obtain the original positioning data. Because the original positioning data is collected through the user plane, and the user plane supports the transmission of high frequency and large data packets, the original positioning data can be quickly obtained.

[0275] In a specific implementation, the first communication device receiving the positioning data sent by the second communication device includes:

[0276] In the case where the first communication device is directly connected to the second communication device, the first communication device receives SBI interface signaling through a control plane, or receives an IP data packet through a user plane;

[0277] In the case where the first communication device is connected to the second communication device through the third communication device, the first communication device receives SBI interface signaling through the control plane, or receives IP data packets through the user plane, or receives positioning data sent by the second communication device through the third communication device;

[0278] The SBI interface signaling or the IP data packet encapsulates the positioning data of the target user equipment that meets the data type.

[0279] In a specific implementation, the positioning data refers to positioning data that satisfies the data type, which can be understood as the target user device providing corresponding positioning data according to the data type provided in the second request, or it can be understood as when the second request does not carry a data type, the target user device provides positioning data according to a local policy, a default policy, or a policy negotiated and specified by the user device and the network side device.

[0280] In an embodiment of the present application, after the second communication device receives the positioning data reported by the target user device through the user plane, the second communication device can transmit the positioning data to the first communication device in a variety of ways. In one embodiment, the second communication device encapsulates the received positioning data into SBI interface signaling or into IP data packets, and then the first communication device receives the encapsulated data (i.e., SBI interface signaling or IP data packets) through the control plane or user plane between the second communication device. In another embodiment, the second communication device directly sends the positioning data to the third communication device, and then the first communication device receives the positioning data through the third communication device.

[0281] In a specific implementation, when the first communication device is directly connected to the second communication device, there is no third communication device at this time, so the positioning data is encapsulated as SBI interface signaling or IP data packets, and then the first communication device receives the SBI interface signaling through the control plane or receives the IP data packets through the user plane. When the first communication device is connected to the second communication device through the third communication device, the first communication device can choose two ways to receive the positioning data, that is, the first communication device can receive the positioning data sent by the second communication device with the help of the third communication device, and can also receive the SBI interface signaling through the control plane or receive the IP data packets through the user plane.

[0282] Accordingly, in order to enable the first communication device to receive the positioning data, the second communication device performs the following steps after receiving the positioning data reported by the target user equipment:

[0283] Step F1: the second communication device encapsulates the received positioning data into SBI interface signaling or into IP data packets;

[0284] Step F2: when the second communication device is connected to the first communication device via the third communication device, the second communication device sends the received positioning data to the first communication device via the third communication device;

[0285] Step F3: When the second communication device is directly connected to the first communication device, the second communication device sends the SBI interface signaling to the first communication device through the control plane, or sends the IP data packet to the first communication device through the user plane.

[0286] In an embodiment of the present application, the second communication device sends the positioning data reported by the target user terminal to the first communication device in a variety of ways, so that the first communication device can use the second communication device to quickly obtain the original positioning data, because the original positioning data is collected through the user plane, and the user plane supports the transmission of high frequency and large data packets, so the original positioning data can be quickly obtained.

[0287] The method for obtaining positioning data proposed in the above embodiment is described through the following embodiment.

[0288] Embodiment 1

[0289] Embodiment 1 describes a process in which the second communication device receives the surface positioning data reported by the target user equipment and then forwards it to the first communication device, taking the first communication device as NWDAF, the second communication device as LMF, the third communication device as GMLC, and the fourth communication device as AMF as an example. Figure 4 As shown, the specific steps are as follows:

[0290] Step 1: NWDAF sends the first request to GMLC.

[0291] Step 2: The NWDAF device verifies whether the NWDAF is authorized to obtain positioning data through the user plane, and verifies whether the UE is authorized to report positioning data through the user plane. If the NWDAF is authorized to obtain positioning data through the user plane, and the UE is authorized to report positioning data through the user plane, execute step 3; otherwise, execute step 11. At this time, the first response generated by executing step 11 carries the first rejection reason. The first rejection reason includes: UE is not authorized to report positioning data through the user plane, NWDAF is not authorized to obtain positioning data through the user plane, UE is not authorized to report positioning data through the user plane, and NWDAF is authorized to obtain positioning data through the user plane.

[0292] Step 3: GMLC sends a request Namf_Location_ProvidePositioningInfo request to AMF (the fourth communication device). The message carries the parameters of the first request in step 1. The message uses an existing lmf interface message or a new message.

[0293] Step 4: The AMF performs LMF selection, that is, determines the second communication device that supports obtaining positioning data through the user plane. Specifically, if the first request includes a user plane collection indication, the second LMF that supports obtaining positioning data through the user plane is determined according to the user plane collection indication, otherwise the selection is performed according to the existing LMF selection logic.

[0294] Step 5: AMF sends a request Nlmf_Location_DetermineLocation to LMF, and the message carries the parameters of the first request.

[0295] Step 6: LMF determines whether to use the user plane to collect positioning data, that is, LMF determines whether to use the user plane to collect positioning data based on information such as business conditions and load conditions. If yes, execute steps 7 and 8; if not, skip steps 7 and 8, and generate a first response, which carries the second rejection reason (for example, there are no available user plane transmission resources and the load of the second communication device exceeds a preset threshold).

[0296] Step 7: LMF sends user plane establishment information to the UE, and the user plane establishment information carries at least one of the following:

[0297] The address of the first communication device;

[0298] Data type data type;

[0299] Task ID:

[0300] Security informationSecure profile.

[0301] Specifically, LMF sends the user plane establishment information to AMF through the AMF interface, and AMF encapsulates the user plane establishment information in a container of the DL NAS TRANSPORT message and sends it to the UE. The DL NAS TRANSPORT message can be an existing privacy verification message (LCS-SS message privacy notification, used to notify the UE whether private information can be disclosed to the outside). It should be noted that the security information Secure profile in the user plane establishment information may not be sent by the first request, but is determined by the LMF itself.

[0302] Step 8: The UE replies to the LMF with an ACK message (i.e., user plane establishment reply information), and the user plane establishment reply information is used to indicate whether the UE accepts reporting positioning data through the user plane. Specifically, the user plane establishment reply information can be an IE or a message. The user plane establishment reply information is encapsulated in a container in the UL NAS transport message and sent to the AMF, and the AMF forwards the container to the LMF. If the UE accepts reporting positioning data through the user plane, the user plane establishment reply information carries an acceptance indication, which can be explicit or implicit (indicated by the message type, for example, if this message is an accept message, it means acceptance, and there is no specific bit to indicate explicitly); if the UE refuses to report positioning data through the user plane, the user plane establishment reply information carries a rejection indication and a second rejection reason (such as the UE refuses to report positioning data through the user plane and refuses to participate in model training).

[0303] Step 9: LMF will send the first response to AMF via Nlmf_Location_DetermineLocation response.

[0304] Step 10: AMF forwards the first response to GMLC via Namf_Location_ProvidePositioningInfo response.

[0305] Step 11: GMLC forwards the first response to NWDAF.

[0306] Step 12: If the UE has not established a PDU session for transmitting positioning data, initiate the PDU establishment process to establish a PDU session for user plane connection. The UE can use the DNN+Slice information configured by URSP to establish a new one. If the UE has already established a PDU session for transmitting positioning data, this step is ignored.

[0307] It should be noted that Figure 4 The UE to UPF in the text refers to a tunnel from the UE to the UPF, not the UE sending control plane signaling to the UPF. In fact, a new PDU session is the UE sending control plane signaling to the SMF. Figure 4 The illustration is a guide for easy understanding.

[0308] Step 13: UE and LMF establish a user plane connection.

[0309] Step 14: The UE sends a message to the LMF via TCP / UDP or Ethernet encapsulation (possibly encapsulated in a non-LPP, non-LCS message). The message sent by the UE carries the positioning information corresponding to the data type data type required in the first request, and also includes the task ID task ID.

[0310] Step 15: After receiving the positioning data reported by the UE, the LMF sends the positioning data to the NWDAF. Specifically, the LMF can send the positioning data to the NWDAF in the following two ways: 1) The LMF directly encapsulates the positioning data into SBI interface signaling or IP data packets, and sends the SBI interface signaling to the NWDAF through the control plane, or sends the IP data packet to the NWDAF through the user plane; 2) The LMF sends the positioning data to the NWDAF through the GMLC.

[0311] Step 16: After receiving the positioning data, NWDAF sends a reply message to GMLC or LMF.

[0312] Step 17: LMF replies or LMF sends information carrying data type data type to UE.

[0313] It should be noted that the data type information can be sent to the UE through step 17, and the NWDAF sends the request information to the LMF, and the LMF can provide the information in the user plane interaction message with the UE. Specifically: LMF initiates a request (second request), and the request carries the required data type, NWDAF task ID and other information. After receiving the request, the UE replies with a response, and carries the data information indicated by the data type in the response, or replies in the response whether to accept the request and provide the data information when reporting subsequent events. Therefore, step 17 in embodiment 1 can occur before step 14.

[0314] Embodiment 2

[0315] Embodiment 2 describes a process in which the second communication device receives the surface positioning data reported by the target user device and then forwards it to the first communication device, taking the first communication device as NWDAF, the second communication device as LMF, and the fourth communication device as AMF as an example, when the first communication device interacts with the second communication device. Figure 5 As shown, the specific steps are as follows:

[0316] Step 1: NWDAF queries LMF that supports obtaining positioning data through the user plane, and directly sends the first request to LM.

[0317] Step 2: LMF determines whether to use the user plane to collect positioning data, that is, LMF determines whether to use the user plane to collect positioning data based on business conditions, load conditions and other information. If yes, execute steps 3 and 4; if not, skip steps 3 and 4, and generate a first response, which carries the second rejection reason (for example, there are no available user plane transmission resources and the load of the second communication device exceeds a preset threshold).

[0318] Step 3: LMF sends user plane establishment information to the UE, and the user plane establishment information carries at least one of the following:

[0319] The address of the first communication device;

[0320] Data type data type;

[0321] Task ID:

[0322] Security informationSecure profile.

[0323] Specifically, LMF sends the user plane establishment information to AMF through the AMF interface, and AMF encapsulates the user plane establishment information in a container of the DL NAS TRANSPORT message and sends it to the UE. The DL NAS TRANSPORT message can be an existing privacy verification message (LCS-SS message privacy notification, used to notify the UE whether private information can be disclosed to the outside). It should be noted that the security information Secure profile in the user plane establishment information may not be sent by the first request, but is determined by the LMF itself.

[0324] Step 4: The UE replies to the LMF with an ACK message (i.e., user plane establishment reply information), which is used to indicate whether the UE accepts reporting positioning data through the user plane. Specifically, the user plane establishment reply information can be an IE or a message. The user plane establishment reply information is encapsulated in a container in the UL NAS transport message and sent to the AMF, and the AMF forwards the container to the LMF. If the UE accepts reporting positioning data through the user plane, the user plane establishment reply information carries an acceptance indication, which can be explicit or implicit (indicated by the message type, for example, if this message is an accept message, it means acceptance, and there is no specific bit to indicate explicitly); if the UE refuses to report positioning data through the user plane, the user plane establishment reply information carries a rejection indication and a second rejection reason (such as the UE refuses to report positioning data through the user plane and refuses to participate in model training).

[0325] Step 5: LMF sends a first response directly to NWDAF. Specifically, the first response is sent via an IP data packet or an SBI interface.

[0326] Step 6: If the UE has not established a PDU session for transmitting positioning data, initiate the PDU establishment process to establish a PDU session for user plane connection. The UE can use the DNN+Slice information configured by URSP to create a new one. If the UE has already established a PDU session for transmitting positioning data, this step is ignored.

[0327] It should be noted that Figure 5 The UE to UPF in the text refers to a tunnel from the UE to the UPF, not the UE sending control plane signaling to the UPF. In fact, a new PDU session is the UE sending control plane signaling to the SMF. Figure 5 The illustration is a guide for easy understanding.

[0328] Step 7: UE and LMF establish a user plane connection.

[0329] Step 8: The UE sends a message to the LMF via TCP / UDP or Ethernet encapsulation (possibly encapsulated in a non-LPP, non-LCS message). The message sent by the UE carries the positioning information corresponding to the data type data type required in the first request, and also includes the task ID task ID.

[0330] Step 9: After receiving the positioning data reported by the UE, the LMF directly encapsulates the positioning data into SBI interface signaling or IP data packets, and sends the SBI interface signaling to the NWDAF through the control plane, or sends the IP data packet to the NWDAF through the user plane.

[0331] Step 10: NWDAF sends an ACK message to LMF.

[0332] Step 11: LMF replies ACK or LMF sends information carrying data type data type to UE.

[0333] It should be noted that the data type information can be sent to the UE through step 11. After the NWDAF sends the request information to the LMF in step 1, the LMF can provide the information in the user plane interaction message with the UE. Specifically: LMF initiates a request (second request), and the request carries the required data type, NWDAF task ID and other information. After receiving the request, the UE replies with a response, and carries the data information indicated by the data type in the response, or replies in the response whether to accept the request and provide the data information when reporting subsequent events. Therefore, step 11 in embodiment 2 can occur before step 8.

[0334] In a second aspect, a method for obtaining positioning data is provided, the method being applied to a second communication device, see Figure 6 FIG. 1 is a flowchart of a method for obtaining positioning data provided by an embodiment of the present application, and the method includes at least the following steps:

[0335] Step S610: The second communication device receives a first request, where the first request is used to request to collect positioning data of a target user equipment through a user plane;

[0336] Step S620: the second communication device generates a second request according to the first request and sends the second request to the target user equipment, where the second request at least includes a data type data type, where the data type is used to indicate a type of positioning data that needs to be reported by the target user equipment;

[0337] Step S630: The second communication device receives the positioning data reported by the target user equipment through the user plane;

In this way, the first communication device uses the second communication device to quickly obtain the positioning data, that is, the first communication device sends a first request to request the second communication device to collect the original positioning data of the target user device through the user plane, and then receives the original positioning data sent by the second communication device. Because the original positioning data is collected through the user plane, and the user plane supports the transmission of high frequency and large data packets, the original positioning data can be quickly obtained.
