[0002] In 5G NR positioning technology, the positioning of connected terminals is mainly supported. In subsequent enhancements, the positioning of terminals in non-connected states (including RRC IDLE state and inactive state) will be studied. The network side cannot determine when the UE side needs to perform UL positioning. If the network side activates the UL positioning reference signal in advance, it will cause additional power consumption and resource waste; if it is based on UE autonomous activation, the network side cannot determine when the UE starts transmitting the UL positioning reference signal, which will cause the network side to need to monitor continuously, and even a large range of receiving nodes to blindly listen to the UL positioning reference signal.

[0250] In this state, the terminal obtains the paging message sent by the core network by monitoring the 5G-S-TMSI;

[0251] A mobility management mechanism with terminal autonomous control is used, that is, the terminal autonomously decides on cell selection and reselection based on measurements.

[0252] At this time, the terminal switches to the RRC connected state through the RRC connection process.

[0253] (2) The INACTIVE state has the following characteristics:

[0254] Based on the network configuration, terminal-controlled mobility is performed, that is, the terminal can move autonomously within the area configured by the network without notifying the network;

[0255] The terminal saves the context of the AS;

[0256] The terminal will also monitor the paging channel, use the 5G system identifier (5G-S-TMSI) to receive paging messages initiated by the core network, and use the inactive radio network temporary identifier (Inactive RNTI, I-RNTI) to obtain paging messages initiated by the RAN;

[0257] Perform periodic updates based on the RAN notification area (RAN-based Notification Area, RNA), as well as updates when the terminal moves out of the RAN notification area.

[0258] 2. Small data transmission (SDT)

[0259] NR is discussing how to send small data in an inactive state. This includes using RRC signaling to transmit small data and not using RRC signaling (i.e. w / o RRC signaling) to transmit small data. Among them, RRC signaling is used to transmit small data, that is, the RRC Resume Request message is sent to the network side together with the small data packet to be transmitted, triggering the subsequent process.

[0260] During the current discussion, it is believed that when using RRC signaling to transmit non-connected small data, the current serving gNB may be different from the anchor gNB. In the case of a small amount of SDT, there may be no need for anchor point switching. Therefore, not performing anchor point switching during non-connected small data transmission is also one of the goals of the R17 SDT project.

[0261] Without anchor point conversion, small data packets in non-connected state can only be performed by the anchor gNB (Packet Data Convergence Protocol, PDCP) packet data convergence protocol layer related operations, including encryption / decryption and integrity protection / validation.

[0262] 3. Positioning process Figure 2 As shown, the overview is as follows:

[0263] Based on an external location service entity, or AMF internal location requirements (e.g. for emergency call locating UE), or UE triggering, the current serving AMF receives a location service request;

[0264] AMF sends the positioning service request to a certain LMF;

[0265] The LMF may trigger positioning-related processes between NG-RAN nodes, such as obtaining auxiliary information or positioning measurement results required for positioning. The LMF and NG-RAN nodes communicate using the NR Positioning Protocol A (NRPPa).

[0266] LMF may also trigger positioning-related processes with UE, such as transmitting positioning assistance information to UE and obtaining positioning measurement or positioning estimation results reported by UE. LMF and UE communicate using the positioning protocol LPP (LTE Positioning Protocol).

[0267] LMF sends the location service response to AMF;

[0268] The AMF sends the location service response to the corresponding location service triggering end.

[0269] Among them, when the terminal is in an idle IDLE state or an inactive state for UL positioning, the network will pre-configure the corresponding UL positioning reference signal for the terminal UE. When the UE enters the idle IDLE state or the inactive state, the uplink reference signal is transmitted based on these pre-configured UL positioning reference signals, thereby reducing the power consumption of the UE. However, after the network pre-configures the UL positioning reference signal for the UE in the idle IDLE state or the inactive state, it cannot determine when to deactivate the UL positioning reference signal. Based on the above, the present application provides a method, device, terminal and network-side equipment for activating a UL positioning reference signal, so as to solve the problem in the prior art that when the network pre-configures the UL positioning reference signal for the UE in the idle IDLE state or the inactive state, it cannot determine when to deactivate the UL positioning reference signal.

[0270] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0271] like Figure 3 As shown, the present application provides a method for activating a UL positioning reference signal, which is applied to a terminal and includes:

[0272] Step 301: When the terminal is in an idle state or an inactive state, the terminal sends a first request message to the network side, where the first request message is used to request activation of a UL positioning reference signal.

[0273] In this application, for the scenario where the network preconfigures the UL positioning reference signal for the terminal, when the terminal is in the IDLE state or the inactive state, a first request message is sent to the network side so that the network side can determine when to deactivate the UL positioning reference signal preconfigured for the UE. Moreover, activating the UL positioning reference signal based on the request of the UE side can avoid the problem of high power consumption of the terminal and high resource consumption on the network side. Moreover, allowing the UE side to send a more appropriate UL positioning reference signal also improves the efficiency of the UL positioning process.

[0274] Optionally, the sending a first request message to the network side includes:

[0275] Sending a first request message to the location management service entity LMF, where the first request message is an LPP activation request message; and / or,

[0278] Optionally, before sending the first request message to the network side, the method further includes:

[0279] The terminal detects that a UL positioning trigger condition is met.

[0280] In the present application, by setting the trigger conditions for UL positioning, only the terminals that meet the UL positioning trigger conditions will send the first request message for requesting activation of the UL positioning reference signal to the location management service entity LMF and / or the base station, thereby avoiding the sending of unnecessary request information and saving resources.

[0292] Optionally, the receiving an activation command sent by the network side includes:

[0320] like Figure 4 As shown, the present application provides a method for activating a UL positioning reference signal, which is applied to a base station and includes:

[0321] Step 401: receiving a first request message sent by a terminal in an idle state or an inactive state, where the first request message is used to request activation of a UL positioning reference signal.
