technical field

The present disclosure relates to the field of wireless technology, and in particular to a terminal positioning method, device, terminal and network side equipment.

Background technique

When the terminal (User Equipment, UE) is in the deactivated state, after the Access and Mobility Management Function (AMF) unit receives the location service request, the AMF will trigger the service request on the network side to establish/activate For the signaling connection with the UE, when the UE is in an idle state, a specific serving next-generation base station (The next Generation Node B, gNB) or an upgraded evolved base station (Next generation eNodeB, ng-eNB) needs to be allocated. Before the positioning process starts, it is assumed that the UE has entered the connected state, that is, before the initial step of the positioning process is triggered, any signaling may be required to switch the UE to the connected state. When the positioning operation is in progress, the pulled-up signaling connection may be subsequently released by the Next Generation Radio Access Network (NG-RAN) due to inactivity of signaling and data.

Current location services only support UEs in the connected state. For example, terminals in factories or shopping malls need periodic positioning, although there are no other services that need to remain in the connected state or switch to the connected state from time to time with the positioning cycle. Since these terminals mainly use location services and rarely have data services, and the process of switching from a deactivated state UE to a connected state will bring a high delay, if the location service of the deactivated state terminals can be realized, it can effectively reduce the The energy consumption of the terminal is reduced, and the delay of the positioning service is reduced.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, the following will describe in detail with reference to the drawings and specific embodiments.

In order to solve the problems in related technologies that a terminal in an inactive state must be converted to a connected state to be able to perform positioning services, resulting in high terminal energy consumption and high time delay in positioning services, an embodiment of the present disclosure provides a terminal positioning method that is in an inactive state. The terminal in the active state can obtain the configuration information of the downlink positioning reference signal from the network side device. In the inactive state, it can perform positioning measurement according to the configuration information, ensuring that the terminal can still perform positioning services after entering the inactive state.

It should be noted that the terminal positioning method described in the embodiments of the present disclosure can be applied to the network-initiated positioning request (Network Induced Location Request, NI-LR) service, and finally the terminal positioning request (Mobile Terminated Location Request, MT-LR) One of the service and the Mobile Originated Location Request (MO-LR) service initiated from the UE.

Take the NI-LR and MT-LR starting from the access and mobility management function (Access and Mobility Management function, AMF) unit to trigger the location service in the location management function (Location Management Function, LMF) as an example, as shown in Figure 1, After the AMF unit receives the location service request for the target UE, it will send the location service request to the LMF unit. LMF processes the positioning service request, using Long Term Evolution Positioning Protocol (LPP) message transmission and New Radio (New Radio, NR) positioning protocol A (NR Positioning Protocol A, NRPPa) transmission, which may include sending to the target UE The assistance data is forwarded to assist UE-based and/or UE-assisted positioning, and/or send the position of the target UE to the positioning requester. The LMF then returns the results of the positioning service (eg, the predicted location of the UE) to the AMF. In the case that other entities (for example, UE, LCS client) other than AMF send requests, AMF will also return location service results to other entities.

In addition, for the MO-LR service, the positioning service client on the UE or user (user) requests some positioning services, for example, reading the position of the UE or transmitting the position of the UE to a third party, and the specific process is different in detail.
