[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] In an exemplary embodiment, as shown in FIG1 , a method for determining a positioning transmission mode is provided, including:

[0044] Step 102, receiving a positioning request; the positioning request includes a quality of service parameter, a service type and a terminal identifier, and the service type is a client type or an application type.

[0045] Among them, the method provided in this embodiment is applied to a core network network element, which can be an AMF (Access and Mobility Management Function) network element or a GMLC (Gateway Mobile Location Center) network element.

[0046] It can be understood that the positioning request can be initiated by the user equipment or by the external client. The service quality parameter can be understood as the QoS (Quality of Service) of the positioning service, including the accuracy and latency required by the positioning. The service type is the client type or the application type; if the positioning request is initiated by the external client, the positioning request carries the client type; if the positioning request is initiated by the user equipment, the positioning request carries the application type; it can be understood as the type of the external client or the application type. The terminal identifier is an identifier used to distinguish different user devices, which can be SUPI (Subscription Permanent Identifier) ​​or GPSI (Generic Public Subscription Identifier).

[0047] Step 104: Determine the positioning priority according to the quality of service parameters and the service type.

[0048] Among them, the AMF network element or GMLC network element is locally configured with a mapping relationship between service quality parameters, service types and positioning priorities, and can assign different positioning priorities to different positioning services. For example, a higher positioning priority can be assigned to a positioning service with a smaller delay.

[0049] Step 106, sending a target positioning request to the LMF network element; the target positioning request includes the positioning priority, the current load of the AMF network element and the terminal identification; wherein the target positioning request is used to request the LMF network element to determine the target positioning transmission mode according to the current load and positioning priority, and interact with the target terminal corresponding to the terminal identification according to the target positioning transmission mode to complete the positioning process, and the target positioning transmission mode is a user plane transmission mode or a control plane transmission mode.

[0050] Among them, the AMF network element refers to the AMF network element where the target terminal (UE) corresponding to the terminal identifier is located. Before executing step 106, the AMF network element also needs to select a suitable LMF network element and send a target positioning request to the selected LMF network element. Optionally, when the current load of the AMF does not exceed the set threshold, for services with a positioning priority higher than the set priority, the user plane transmission mode is preferentially adopted, and a lower positioning delay can be obtained; the services with a positioning priority lower than the set priority are diverted to the control plane. If the current load of the AMF exceeds the set threshold, all positioning services adopt the user plane transmission mode, but different user plane transmission quality parameters can be configured for services of different priorities, and high-priority positioning service messages are preferentially transmitted, thereby ensuring that higher-priority services obtain lower positioning delays. Among them, the threshold value of the AMF load (i.e., the set threshold) and the mapping relationship between the priority and the transmission mode can be dynamically configured in the LMF network element. The user plane transmission mode can be understood as the transmission of positioning data using the data transmission mode, and the control plane transmission mode can be understood as the transmission of positioning data through the core network signaling transmission mode.

[0051] The LMF network element starts the positioning process according to the selected target positioning transmission mode. If the user plane transmission mode is selected, the LMF network element actively initiates the positioning user plane connection establishment process; if the control plane transmission mode is selected, the LMF network element sends the corresponding positioning message to the target terminal through the AMF network element.

[0052] In an optional implementation, referring to FIG. 2 , the method for determining the positioning transmission mode of the present application is applied to the AMF network element. Among them, the external client sends a positioning request to the GMLC network element, and the positioning request includes service quality parameters, client type and terminal identification. The GMLC network element sends the positioning request to the AMF network element where the target UE corresponding to the terminal identification is located. After receiving the request, the AMF network element wakes up the target UE to a connected state, and determines the positioning priority based on the service quality parameters and the client type. The AMF network element selects the LMF network element and sends a positioning request to the LMF network element, and the positioning request includes positioning priority, AMF load, terminal identification, service quality parameters, etc. The LMF network element determines the positioning transmission mode based on the AMF load and positioning priority, and uses the selected positioning transmission mode to perform the positioning process.

[0053] In an optional implementation, referring to FIG. 3 , the method for determining the positioning transmission mode of the present application is applied to a GMLC network element. Among them, an external client sends a positioning request to the GMLC network element, and the positioning request includes service quality parameters, client type and terminal identification. The GMLC network element determines the positioning priority according to the service quality parameters and the client type, and transmits the positioning request to the LMF network element through the AMF network element where the target UE corresponding to the terminal identification is located, and the positioning request includes positioning priority, AMF load, terminal identification, service quality parameters, etc. After receiving the request, the AMF network element wakes up the target UE to a connected state. The LMF network element determines the positioning transmission mode according to the AMF load and positioning priority, and uses the selected positioning transmission mode to perform the positioning process.

[0054] In an optional implementation, referring to FIG. 4 , the method for determining the positioning transmission mode of the present application is applied to the AMF network element. After the target UE enters the connected state, it sends a positioning request to the AMF network element, and the positioning request includes parameters such as service quality parameters, application type, and terminal identification; after receiving the request, the AMF network element determines the positioning priority according to the service quality parameters and application type. The AMF network element selects the LMF network element and sends a positioning request to the LMF network element, and the positioning request includes positioning priority, AMF load, terminal identification, service quality parameters, etc. The LMF network element determines the positioning transmission mode according to the AMF load and positioning priority, and uses the selected positioning transmission mode to perform the positioning process.

[0055] In the above-mentioned method for determining the positioning transmission mode, a positioning request is received; the positioning request includes service quality parameters, service type and terminal identification, and the service type is client type or application type; the positioning priority is determined according to the service quality parameters and service type; a target positioning request is sent to the LMF network element; the target positioning request includes the positioning priority, the current load of the AMF network element and the terminal identification; wherein the target positioning request is used to request the LMF network element to determine the target positioning transmission mode according to the current load and positioning priority, and to interact with the target terminal corresponding to the terminal identification according to the target positioning transmission mode to complete the positioning process, and the target positioning transmission mode is a user plane transmission mode or a control plane transmission mode. Through the above-mentioned method, different positioning priorities are determined according to the positioning service quality parameters and service type, and based on parameters such as positioning priority and AMF load, a suitable positioning transmission mode is selected to match the positioning service requirements and improve the transmission efficiency of positioning data.

[0056] In an exemplary embodiment, the method further includes: receiving a positioning request from a GMLC network element; determining whether the positioning request includes a positioning priority; if not, executing step 104.

[0057] Among them, the method for determining the positioning transmission mode provided in this example is applied to the AMF network element.

[0058] Since the GMLC network element has the ability to determine the positioning priority, optionally, the GMLC network element receives an initial positioning request from an external client, the initial positioning request includes service quality parameters, client type and terminal identification; determines the positioning priority according to the service quality parameters and the client type; sends a positioning request to the AMF network element corresponding to the terminal identification, the positioning request includes service quality parameters, client type, terminal identification and positioning priority; the AMF network element receives the positioning request from the GMLC network element, determines that the request includes the positioning priority, and then sends a target positioning request to the LMF network element.

[0059] Optionally, the GMLC network element receives a positioning request from an external client and sends the positioning request to the AMF network element; the AMF network element receives the positioning request from the GMLC network element, determines that the positioning priority is not included therein, determines the positioning priority according to the quality of service parameters and the service type, and sends a target positioning request to the LMF network element.

[0060] In this embodiment, both the GMLC network element and the AMF network element have the ability to determine the positioning priority. The GMLC network element or the AMF network element can be selected to determine the positioning priority according to actual needs, which is more flexible. For example, in a scenario where centralized management and control of positioning services are required, the GMLC network element determines the positioning priority, and in a scenario where rapid response and flexible adjustment are required, the AMF network element determines the positioning priority. In this way, double protection is set up. In the case where the GMLC network element cannot determine the positioning priority, the AMF network element can be used as a backup option to continue to provide positioning services, ensuring the stability of the network and the reliability of positioning transmission.

[0061] In an exemplary embodiment, the method further includes: receiving a positioning request from a target terminal in a connected state.

[0062] The method for determining the positioning transmission mode provided in this example is applied to the AMF network element. Referring to Figure 4, the target terminal in the connected state sends a positioning request, and in response to the positioning request, the AMF network element performs subsequent processing steps.

[0063] In an exemplary embodiment, step 104 includes: querying a mapping table according to the quality of service parameter and the service type to determine a corresponding positioning priority.

[0064] Among them, the local configuration of the AMF network element or the GMLC network element has a mapping table, which includes the mapping relationship between QoS and positioning priority, and the mapping relationship between client type (or application type) and positioning priority. The mapping relationship can be configured according to actual needs. In an optional implementation method, the mapping relationship can be that the smaller the delay, the higher the positioning priority, and the higher the importance of the client type, the higher the positioning priority. In this way, a higher priority is provided for positioning services with higher latency requirements, and a higher priority is provided for positioning services of key service types.

[0065] In an exemplary embodiment, as shown in FIG5 , a method for determining a positioning transmission mode is provided, including:

[0066] Step 502, receiving a target positioning request from the AMF network element; the target positioning request includes positioning priority, current load of the AMF network element and terminal identification.

[0067] Among them, the method for determining the positioning transmission mode provided in this embodiment is applied to the LMF network element.

[0068] Optionally, the AMF network element performs the following steps: receiving a positioning request from a GMLC network element or a target terminal; the positioning request includes quality of service parameters, service type and terminal identifier, where the service type is a client type or an application type; determining the positioning priority based on the quality of service parameters and the service type; and sending a target positioning request to the LMF network element.

[0069] Optionally, the GMLC network element receives a positioning request from an external client, the positioning request including service quality parameters, client type and terminal identifier, determines the positioning priority based on the service quality parameters and client type, and sends the target positioning request to the LMF network element through the AMF network element corresponding to the terminal identifier.

[0070] Step 504, determining the target positioning transmission mode according to the current load and positioning priority; the target positioning transmission mode is a user plane transmission mode or a control plane transmission mode.

[0071] Step 506: interact with the target terminal corresponding to the terminal identifier according to the target positioning transmission mode to complete the positioning process.

[0072] The description of steps 502 to 506 can refer to the explanation of the aforementioned steps 102 to 106, which will not be repeated here.

[0073] In the above method for determining the positioning transmission mode, a target positioning request is received from an AMF network element; the target positioning request includes positioning priority, the current load of the AMF network element and the terminal identification; the target positioning transmission mode is determined according to the current load and the positioning priority; the target positioning transmission mode is a user plane transmission mode or a control plane transmission mode; according to the target positioning transmission mode, the target terminal corresponding to the terminal identification is interacted with to complete the positioning process. Through the above method, based on parameters such as positioning priority and AMF load, a suitable positioning transmission mode is selected to match the positioning service requirements and improve the transmission efficiency of positioning data.

[0074] In an exemplary embodiment, the target positioning transmission mode is determined according to the current load and the positioning priority, including: when the current load is less than or equal to a set threshold, if the positioning priority is higher than the set priority, the target positioning transmission mode is determined to be a user plane transmission mode; if the positioning priority is not higher than the set priority, the target positioning transmission mode is determined to be a control plane transmission mode; when the current load is greater than the set threshold, the target positioning transmission mode is determined to be a user plane transmission mode.

[0075] Among them, when the current load of AMF does not exceed the set threshold, for services with a positioning priority higher than the set priority, the user plane transmission method is preferentially used to obtain a lower positioning delay; the services with a positioning priority lower than the set priority are diverted to the control plane, that is, for services with a positioning priority not higher than the set priority, the control plane transmission method is used. If the current load of AMF exceeds the set threshold, all positioning services use the user plane transmission method. Among them, the set threshold, the set priority, and the mapping relationship between the priority and the transmission method can be dynamically configured in the LMF network element, and this embodiment does not limit the specific numerical value.

[0076] In an optional implementation, the method further includes: determining the target positioning transmission mode according to the current load, positioning priority and terminal capability of the target terminal, the target terminal being the user equipment corresponding to the terminal identifier. In a specific implementation, the terminal capability is used to indicate the positioning transmission mode supported by the target terminal; when the current load is less than or equal to the set threshold, if the positioning priority is higher than the set priority and the target terminal supports the user plane transmission mode, the target positioning transmission mode is determined to be the user plane transmission mode; if the positioning priority is not higher than the set priority and the target terminal supports the control plane transmission mode, the target positioning transmission mode is determined to be the control plane transmission mode; when the current load is greater than the set threshold, if the target terminal supports the user plane transmission mode, the target positioning transmission mode is determined to be the user plane transmission mode.

[0077] Among them, the terminal capability of the target terminal is taken into consideration to ensure that the selected target positioning transmission method can be implemented normally, thus avoiding errors and improving the reliability of positioning transmission.

[0078] In an exemplary embodiment, the target positioning request also includes a service quality parameter; the method also includes: when the current load is greater than a set threshold, configuring the user plane transmission quality parameter according to the service quality parameter and the positioning priority; based on the user plane transmission quality parameter, using the user plane transmission method to interact with the target terminal to complete the positioning process.

[0079] Different user plane transmission quality parameters are configured for services of different priorities, and high-priority positioning service messages are transmitted first, thereby ensuring that higher-priority services obtain lower positioning delays. User plane transmission quality parameters refer to the QoS service quality parameters carried by the user plane, which may include QoS classification identification, guaranteed bit rate (GBR), maximum bit rate (MBR), etc.

[0080] A policy for configuring user-plane transmission quality parameters based on service quality parameters and positioning priorities is pre-set in the LMF network element. In an optional implementation, the LMF network element locally stores multiple groups of delay ranges, priorities, and corresponding QoS parameters; after obtaining the service quality parameters and positioning priorities currently requested, the LMF network element searches the local storage space based on the delay parameters and positioning priorities required in the service quality parameters, determines the delay range that includes the delay parameters, the priority that is consistent with the positioning priority, and the corresponding QoS parameters in the local storage space; and uses the queried QoS parameters as the user-plane transmission quality parameters for this configuration.

[0081] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0082] Based on the same inventive concept, the embodiment of the present application also provides a positioning transmission system for implementing the method for determining the positioning transmission mode involved above. The implementation scheme for solving the problem provided by the system is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more positioning transmission system embodiments provided below can refer to the limitations of the method for determining the positioning transmission mode above, and will not be repeated here.

[0083] In an exemplary embodiment, as shown in FIG6 , a positioning transmission system is provided, including an AMF network element 601 and an LMF network element 602; wherein:

[0084] AMF network element 601 is used to receive a positioning request, which includes service quality parameters, service type and terminal identification, where the service type is client type or application type; determine the positioning priority based on the service quality parameters and service type; and send a target positioning request to LMF network element 602, which includes the positioning priority, the current load of AMF network element 601 and the terminal identification.

[0085] The LMF network element 602 is used to determine the target positioning transmission mode according to the current load and positioning priority, and the target positioning transmission mode is a user plane transmission mode or a control plane transmission mode; interact with the target terminal corresponding to the terminal identifier according to the target positioning transmission mode to complete the positioning process.

Through the above-mentioned method, the AMF network element determines different positioning priorities according to the positioning service quality parameters and service type. The LMF network element selects a suitable positioning transmission mode based on parameters such as positioning priority and AMF load to match the positioning service requirements and improve the transmission efficiency of positioning data.

[0087] In an exemplary embodiment, referring to FIG. 6 , the system further includes a GMLC network element 603; wherein:

[0090] Wherein, referring to Figure 7, the external client sends an initial positioning request to the GMLC network element, and the initial positioning request includes service quality parameters, client type and terminal identification. The GMLC network element determines the positioning priority according to the service quality parameters and the client type, and sends a positioning request, service quality parameters, client type, terminal identification and positioning priority to the AMF network element where the target UE corresponding to the terminal identification is located. After receiving the request, the AMF network element wakes up the target UE to the connected state and determines whether the positioning priority is included in the positioning request. If it exists, the AMF network element selects the LMF network element and sends a target positioning request to the LMF network element. If it does not exist, the AMF network element determines the positioning priority according to the service quality parameters and the client type, selects the LMF network element, and sends a target positioning request to the LMF network element. The target positioning request includes positioning priority, AMF load, terminal identification, service quality parameters, etc. The LMF network element determines the positioning transmission mode according to the AMF load and positioning priority, and uses the selected positioning transmission mode to perform the positioning process.
