Such as a Station (STA), subscriber unit (subscriber unit), subscriber Station (subscriber Station), mobile Station (mobile), remote Station (remote Station), access point, remote terminal (remote terminal), access terminal (access terminal), user equipment (user terminal), user agent (user agent), user device (user equipment), or User Equipment (UE). Alternatively, the terminal 11 may be an unmanned aerial vehicle device. Alternatively, the terminal 11 may be a vehicle-mounted device, for example, a car-driving computer having a wireless communication function, or a wireless communication device externally connected to the car-driving computer. Alternatively, the terminal 11 may be a roadside device, for example, a street lamp, a signal lamp, or other roadside devices having a wireless communication function.

The base station 12 may be a network-side device in a wireless communication system. Wherein the wireless communication system may be a fourth generation mobile communication technology (the 4th generation mobile communication,4G) system, also known as a long term evolution (Long Term Evolution, LTE) system; alternatively, the wireless communication system may be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next generation system of the 5G system. Among them, the access network in the 5G system may be called NG-RAN (New Generation-Radio Access Network, new Generation radio access network). Or, an MTC system.

Wherein the base station 12 may be an evolved base station (eNB) employed in a 4G system. Alternatively, the base station 12 may be a base station (gNB) in a 5G system employing a centralized and distributed architecture. When the base station 12 employs a centralized and distributed architecture, it typically includes a Centralized Unit (CU) and at least two Distributed Units (DUs). A protocol stack of a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a medium access control (Media Access Control, MAC) layer is provided in the centralized unit; a Physical (PHY) layer protocol stack is provided in the distribution unit, and the specific implementation of the base station 12 is not limited by the embodiment of the present disclosure.

In order to better understand the technical solution described in any embodiment of the present disclosure, first, a terminal positioning scenario is described by an embodiment.

Referring to fig. 2, the network communication system includes a terminal and a location management function (LMF, location Management Function). The states of the terminals are classified into a radio resource control (RRC, radio Resource control) connected state and an RRC unconnected state. The RRC non-connected state includes an RRC idle state and an RRC inactive state. When the network needs to locate the terminal in the RRC-connected state, a location request is initiated to the terminal through a long term evolution LTE positioning protocol (LPP, LTE Positioning Protocol) request location information (Request Location Information) message. The LPP request location information message mainly includes two parts, wherein one part is a common configuration parameter of various alternative location modes adopted by the terminal in the RRC connection state, and the other part is a configuration parameter unique to the various alternative location modes. And after the terminal in the RRC connection state receives the positioning request, positioning measurement is completed according to the configuration information in the positioning request, and a positioning measurement result or position information is reported to a positioning management function. However, for a terminal in an RRC idle state or an RRC inactive state, since the LMF cannot transmit a location request to the terminal, location information of the terminal in the RRC idle state or the RRC inactive state cannot be obtained.

As shown in fig. 3, an embodiment of the present disclosure provides a terminal positioning method, which is applied to a terminal, and includes:

step 31, when the terminal is in a Radio Resource Control (RRC) connection state, receiving a request message carrying a position information request; wherein the location information request includes: first configuration information for positioning the terminal; the first configuration information is used for carrying out positioning measurement according to the positioning request information after the terminal is switched to the RRC non-connected state so as to obtain a positioning result; the RRC non-connected state includes: an RRC idle state or an RRC inactive state.

Here, the terminal includes, but is not limited to: cell phone, wearable device, vehicle terminal, intelligent home equipment and/or intelligent office equipment.

In one embodiment, the request message is a long term evolution, LTE, positioning protocol, LPP, message, or any other message. For ease of illustration, the embodiments of the present disclosure are described below with LLP messages as examples, but this is not a limitation of the embodiments of the present disclosure.

In one embodiment, when a terminal in a radio resource control RRC connected state receives a request message carrying a location information request, it does not immediately use the first configuration information included in the location information request in the request message to perform a positioning measurement. But stores the request message and performs positioning measurement using the first configuration information included in the position information request in the stored request message when the terminal is switched from the RRC connected state to the RRC non-connected state.

In one embodiment, when a request message carrying a location information request is received, the request message is saved. Here, if the terminal receives the request message a plurality of times, it may update the stored request message with the latest received request message after each time the request message is received. In this way, the stored request message is always the latest received request message.

In one embodiment, the request message may be a request message dedicated to positioning of the terminal in the RRC non-connected state. Here, the request message is a request message specially used for positioning the terminal in the RRC non-connected state, so that the encoding and decoding of the request message in the message transmission process can be higher without mixing with other information, and the transmission efficiency of the request message is improved. In another embodiment, the request message may also be a generic request message. Here, the general request message may be a message common to a request message for positioning of a terminal in an RRC connected state. Here, the request message for positioning the terminal in the RRC connected state and the request message for positioning the terminal in the RRC disconnected state are all universal request messages, so that the types of the request messages are reduced, and the detection complexity when the terminal receives the messages is reduced.

In one embodiment, when the universal request message is for the terminal in the RRC connected state, the terminal in the RRC connected state performs positioning measurement of the terminal using the universal request message immediately after receiving the universal request message; when the universal request message is used for the terminal in the RRC non-connection state, the terminal in the RRC connection state does not immediately utilize the universal request message to carry out positioning measurement of the terminal after receiving the universal request message, but stores the universal request message, and after the terminal is switched from the RRC connection state to the RRC non-connection state, the stored universal request message is utilized to carry out positioning measurement of the terminal.

In one embodiment, the generic request message contains an indication identifier. When the value of the indication mark is a first value, the universal request message is used for positioning the terminal in the RRC connection state; when the value of the indication identifier is the second value, the universal request message is used for positioning the terminal in the RRC non-connection state.

In another embodiment, when the generic request message includes the indication identifier, the generic request message is used for positioning the terminal in the RRC non-connected state; when the general request message does not contain the indication identifier, the general request message is used for positioning the terminal in the RRC connection state.

In one embodiment, the first configuration information may include one or more of the following information during terminal positioning: the information of the adopted positioning mode, the information of the positioning measurement precision requirement, the effective time information of the first configuration information, the positioning measurement area and the positioning measurement frequency information.

In the embodiment of the disclosure, when the terminal is in the RRC connected state, a request message carrying a location information request is issued to the terminal in advance, so that the terminal can directly perform positioning measurement based on the issued first configuration information after switching from the RRC connected state to the RRC disconnected state, and compared with the mode that the terminal in the RRC disconnected state needs to switch to the RRC connected state because the terminal cannot obtain the first configuration information, the time delay is smaller in a mode of acquiring the first configuration information through the request message received in the connected state and switching back to the disconnected state to perform positioning measurement. Thus, the rapid positioning measurement of the communication network in the RRC non-connection state of the terminal is realized.

In one embodiment, the first configuration information may include one or more of common configuration parameters, positioning mode information, validity time information, validity range information.

In one embodiment, the alternative positioning modes include a first alternative positioning mode, a second alternative positioning mode and a third alternative positioning mode, and the first alternative positioning mode, the second alternative positioning mode and the third alternative positioning mode all include configuration parameters of the positioning number, and then the common configuration parameters include the positioning number.

In one embodiment, the common configuration parameters may further include one or more of the following: information of spatial reference points, information of reference signals and format parameters of positioning data. Here, the information of the spatial reference point may be information of a positioning satellite. The information of the reference signal may be information of a signal transmitted by a spatial reference point. The format of the positioning data may be a format of data in which the terminal reports the positioning result to the base station.

In one embodiment, the alternate positioning modes include a first alternate positioning mode, a second alternate positioning mode, and a third alternate positioning mode. If the second alternative mode is a positioning mode for positioning measurement by using the terminal, the positioning mode information comprises information of the second alternative mode.

In one embodiment, the valid time range may include a timing start point and a timing end point. For example, the start point of the timer is 1 st second and the end point of the timer is 3 rd second. In another embodiment, the valid time range may include a timing start point and a duration. For example, the starting point of the timer is 1 st second and the duration is 2 seconds.

In one embodiment, the timing start point may be a point in time when the terminal receives a request message carrying a location information request.

In another embodiment, the timing start point may be a point of time when the terminal switches from the RRC connected state to the RRC non-connected state.

In one embodiment, the timer may be set to be a set duration, the timer is started when the starting point of the timer expires, and the first configuration information is disabled when the duration counted by the timer is the set duration.

In one embodiment, the effective spatial range may be a pre-set communication cell range. In one embodiment, the communication cell range may be preset by setting a communication cell identity list. Referring to table one, the communication cell identity list includes communication cell range information and cell identity information. And here, in the communication cell identity list, the communication cell range includes a first communication cell range including cells whose cell identity information is a and B and a second communication cell range including cells whose cell identity information is C and D. The first configuration information is valid when the terminal is within the communication cell indicated by the cell identity list. The first configuration information is disabled when the terminal is not within the communication cell indicated by the cell identity list. For example, the first configuration information is valid when the terminal is in the a cell.
