in step 201a, the UE does not support sending an uplink positioning reference signal and does not support measuring a downlink positioning reference signal, and determines not to use SDT to send MO-LR message to the network side device.

In one embodiment of the present disclosure, when the UE does not support sending an uplink positioning reference signal and does not support measuring a downlink positioning reference signal (i.e., the UE does not support uplink positioning capability and does not support downlink positioning capability), it is indicated that the UE cannot perform a positioning procedure in a non-connected state, and it is determined that the MO-LR message is not sent to the network side device using SDT.

Fig. 2b is a flowchart of a positioning method according to another embodiment of the present disclosure, which is applied to a UE in an RRC non-connected state, as shown in fig. 2b, and the positioning method may include the following steps:

As can be seen from the above, when it is determined in the above step 201b that the MO-LR message is not sent to the network side device by using the SDT, it is described that: the UE in the RRC non-connected state needs to perform the positioning procedure, but the UE in the RRC non-connected state cannot perform the positioning procedure. At this time, in order to ensure that the positioning procedure to be executed can be successfully performed, when the UE in the RRC non-connected state transitions to the RRC connected state, an MO-LR message may be sent to the network side device to trigger the positioning operation.

Among other things, in one embodiment of the present disclosure, the manner in which the request to the network side device to switch to the RRC connected state is determined may also be different for different scenarios.

Specifically, in one embodiment of the present disclosure, when a UE in an RRC non-connected state receives an LPP message, where the LPP message is specifically used to trigger a downlink positioning procedure, based on this, it needs to be determined whether the UE in the RRC non-connected state supports measurement of a downlink positioning reference signal, that is, whether the UE supports downlink positioning capability, and if the UE does not support measurement of the downlink positioning reference signal, it indicates that the UE currently in the RRC non-connected state cannot perform the downlink positioning procedure triggered by the LPP message, and then may request to switch to the RRC connected state from the network side device to perform the downlink positioning procedure.

Further, in another embodiment of the present disclosure, an Event for triggering a positioning procedure may be configured for a UE, when the UE in an RRC non-connected state detects an Event (Event detected), it is determined whether the positioning capability of the UE in the non-connected state supports to perform the Event, and when the Event is not supported to be performed, a handover to the RRC connected state may be requested to the network side device.

By way of example, in one embodiment of the present disclosure, the event may be, for example: and configuring the UE to periodically send the uplink positioning reference signal, wherein when the UE detects the event of configuring the UE to periodically send the uplink positioning reference signal, whether the UE supports sending the uplink positioning reference signal currently can be determined, and if the UE does not support sending the uplink positioning reference signal, the UE can request the network side equipment to switch to an RRC connection state so as to execute the event-triggered positioning operation. The positioning operation may specifically be: and sending an MO-LR message to the network side equipment, receiving a fourth positioning message sent by the network side equipment based on the MO-LR message, and performing positioning operation based on the fourth positioning message, wherein the fourth positioning message is sent by the network side equipment based on positioning capability supported by the UE in an RRC connection state. Such as: and the network side equipment indicates the UE to locate through downlink locating operation, and the UE uses the downlink locating operation to locate. Such as: and the network side equipment indicates the UE to locate through uplink locating operation, and the UE uses the uplink locating operation to locate. How a specific UE uses an uplink positioning operation, a downlink positioning operation for positioning is a conventional positioning operation in the art.

In another embodiment of the present disclosure, the "UE supporting the capability of measuring the downlink positioning reference signal and the capability of transmitting the uplink positioning reference signal" in the step 301a may not inherit the determination result of determining the positioning capability of the UE in the step 101 a.
