Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
In an exemplary embodiment, as shown in fig. 1, a method for determining a positioning transmission mode is provided, including:
Step 102, receiving a positioning request, wherein the positioning request comprises a service quality parameter, a service type and a terminal identifier, and the service type is a client type or an application type.
The method provided in this embodiment is applied to a core network element, where the core network element may be an AMF (ACCESS AND Mobility Management Function, mobility management function) network element, or may be a GMLC (Gateway Mobile Location Center ) network element.
It will be appreciated that the location request may be initiated by the user equipment or by an external client. The quality of service parameter may be understood as QoS (Quality of Service ) of the positioning service, including information on accuracy, delay, etc. of the positioning requirement. The service type is a client type or an application type, if the positioning request is initiated by an external client, the positioning request carries the client type, if the positioning request is initiated by user equipment, the positioning request carries the application type, and the positioning request can be understood as the type of the external client or the application type. The terminal identifier is an identifier for distinguishing different user equipments, and may be a SUPI (subscriber identity PERMANENT IDENTIFIER) or a GPSI (Generic Public Subscription Identifier, general public user identity).
And 104, determining the positioning priority according to the service quality parameter and the service type.
The AMF network element or the GMLC network element is locally configured with a mapping relationship between a quality of service parameter, a service type and a positioning priority, so that different positioning priorities can be allocated to different positioning services, for example, a higher positioning priority can be allocated to a positioning service with smaller time delay.
And step 106, a target positioning request is sent to the LMF network element, wherein the target positioning request comprises a positioning priority, the current load of the AMF network element and a terminal identifier, and the target positioning request is used for requesting the LMF network element to determine a target positioning transmission mode according to the current load and the positioning priority, and interacting with a target terminal corresponding to the terminal identifier according to the target positioning transmission mode to complete a positioning process, wherein the target positioning transmission mode is a user plane transmission mode or a control plane transmission mode.
The AMF network element refers to an AMF network element where a target terminal (UE) corresponding to the terminal identifier is located. Before executing step 106, the AMF network element further needs to select an appropriate LMF network element, and send a target location request to the selected LMF network element. Optionally, when the current load of the AMF does not exceed the set threshold, the user plane transmission mode is preferentially adopted for the service with the positioning priority higher than the set priority, so that lower positioning time delay can be obtained, and the service with the positioning priority lower than the set priority is shunted to the control plane. If the current load of AMF exceeds the set threshold, all positioning services adopt a user plane transmission mode, but different user plane transmission quality parameters can be configured for services with different priorities, and positioning service messages with high priorities are transmitted preferentially, so that the service with higher priority is ensured to obtain lower positioning time delay. The threshold value threshold (i.e. set threshold value) of the AMF load and the mapping relation between the priority and the transmission mode can be dynamically configured in the LMF network element. The user plane transmission mode may be understood as transmitting the positioning data by using a data transmission mode, and the control plane transmission mode may be understood as transmitting the positioning data by using a core network signaling transmission mode.
And the LMF network element starts a positioning process according to the selected target positioning transmission mode. And if the transmission mode of the control plane is selected, the LMF network element sends a corresponding positioning message to the target terminal through the AMF network element.

And after the AMF network element receives the request, the target UE is awakened to a connection state, and the positioning priority is determined according to the service quality parameter and the client type. The AMF network element selects an LMF network element and sends a positioning request to the LMF network element, wherein the positioning request comprises positioning priority, AMF load, terminal identification, service quality parameters and the like. And the LMF network element determines a positioning transmission mode according to the AMF load and the positioning priority, and uses the selected positioning transmission mode to carry out a positioning flow.
In an alternative implementation, referring to fig. 3, the method for determining a location transmission mode of the present application is applied to a GMLC network element. The external client sends a positioning request to the GMLC network element, wherein the positioning request comprises a service quality parameter, a client type and a terminal identifier. The GMLC network element determines the positioning priority according to the service quality parameter and the client type, and transmits a positioning request to the LMF network element through an AMF network element where the target UE corresponding to the terminal identifier is located, wherein the positioning request comprises the positioning priority, the AMF load, the terminal identifier, the service quality parameter and the like. And after the AMF network element receives the request, the target UE is awakened to a connection state. And the LMF network element determines a positioning transmission mode according to the AMF load and the positioning priority, and uses the selected positioning transmission mode to carry out a positioning flow.
In an alternative implementation, referring to fig. 4, the method for determining a positioning transmission mode of the present application is applied to an AMF network element. After the target UE enters a connection state, a positioning request is sent to an AMF network element, wherein the positioning request comprises parameters such as a service quality parameter, an application type, a terminal identifier and the like, and after the AMF network element receives the request, the positioning priority is determined according to the service quality parameter and the application type. The AMF network element selects an LMF network element and sends a positioning request to the LMF network element, wherein the positioning request comprises positioning priority, AMF load, terminal identification, service quality parameters and the like. And the LMF network element determines a positioning transmission mode according to the AMF load and the positioning priority, and uses the selected positioning transmission mode to carry out a positioning flow.

In this way, double guarantee is set, and under the condition that the GMLC network element cannot determine the positioning priority, the AMF network element can serve as a backup option to continue to provide positioning service, so that the stability of the network and the reliability of positioning transmission are ensured.

And step 506, interacting with the target terminal corresponding to the terminal identifier according to the target positioning transmission mode, and completing the positioning process.
The descriptions of steps 502 to 506 can be referred to the descriptions of steps 102 to 106, and are not repeated here.
