INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A positioning method in a 5G cellular network includes a UE receiving a radio resource control (RRC) release message, the RRC release message carrying positioning assistance information. The positioning assistance information is used to perform positioning measurement to obtain a positioning result when the UE is in an RRC non-connected state; and the RRC non-connected state includes an RRC idle state and an RRC inactive state. ## Claims ### Claim 1 A positioning method, comprising: in response to receiving a positioning request, determining whether positioning assistance information is valid; and in response to the positioning assistance information being valid, performing a positioning measurement, wherein a user equipment, UE, is in a radio resource control, RRC, non-connected state; wherein determining whether positioning assistance information is valid comprises at least one of: determining whether a current time is within the valid time range of the positioning assistance information; or determining whether the UE is located within a valid space range of the positioning assistance information. ### Claim 2 (depends on 1) The method of claim 1, wherein determining whether the UE is located within the valid space range of the positioning assistance information comprises: determining that the positioning assistance information is valid if a cell where the UE resides is a cell within the valid space range. ### Claim 3 (depends on 1) The method of claim 1, wherein determining whether the UE is located within the valid space range of the positioning assistance information comprises: determining that the positioning assistance information is invalid when the cell where the UE resides is not within the valid space range. ### Claim 4 (depends on 1) The method of claim 1, wherein the positioning assistance information comprises at least one of: measurement configuration of a positioning reference signal being used to indicate resource location information of the positioning reference signal; cell public channel configuration for performing the positioning measurement; valid time range indication information configured to indicate the valid time range of the positioning assistance information; and valid space range indication information configured to indicate the valid space range of the positioning assistance information. ### Claim 5 A UE comprising a processor, a transceiver, a memory, and executable programs stored on the memory and capable of being executed by the processor, wherein when the processor runs the executable programs, the processor is configured to: determine whether positioning assistance information is valid in response to receiving a positioning request; and perform a positioning measurement in response to the positioning assistance information being valid, wherein the UE is in the a radio resource control, RRC, non-connected state; wherein the processor is further configured to determine whether positioning assistance information is valid by at least one of: determining whether a current time is within the valid time range of the positioning assistance information; or determining whether the UE is located within a valid space range of the positioning assistance information. ### Claim 6 (depends on 5) The UE of claim 5, wherein the processor is further configured to determine whether the UE is located within the valid space range of the positioning assistance information by: determining that the positioning assistance information is valid if a cell where the UE resides is a cell within the valid space range. ### Claim 7 (depends on 5) The UE of claim 5, wherein the processor is further configured to determine whether the UE is located within the valid space range of the positioning assistance information by: determining that the positioning assistance information is invalid when the cell where the UE resides is not within the valid space range. ### Claim 8 (depends on 5) The UE of claim 5, wherein the positioning assistance information comprises at least one of: measurement configuration of a positioning reference signal being used to indicate resource location information of the positioning reference signal; cell public channel configuration for performing the positioning measurement; valid time range indication information configured to indicate the valid time range of the positioning assistance information; and valid space range indication information configured to indicate the valid space range of the positioning assistance information. ### Claim 9 A non-transitory computer-readable storage medium having executable programs stored thereon, wherein when the executable programs are executed by a processor, implement following steps: in response to receiving a positioning request, determining whether positioning assistance information is valid; and in response to the positioning assistance information being valid, performing a positioning measurement, wherein a user equipment, UE, is in a radio resource control, RRC, non-connected state; wherein determining whether positioning assistance information is valid comprises at least one of: determining whether a current time is within the valid time range of the positioning assistance information; or determining whether the UE is located within a valid space range of the positioning assistance information. ### Claim 10 (depends on 9) The non-transitory computer-readable storage medium of claim 9, wherein determining whether the UE is located within the valid space range of the positioning assistance information comprises: determining that the positioning assistance information is valid if a cell where the UE resides is a cell within the valid space range. ### Claim 11 (depends on 9) The non-transitory computer-readable storage medium of claim 9, wherein determining whether the UE is located within the valid space range of the positioning assistance information comprises: determining that the positioning assistance information is invalid when the cell where the UE resides is not within the valid space range. ### Claim 12 (depends on 9) The non-transitory computer-readable storage medium of claim 9, wherein the positioning assistance information comprises at least one of: measurement configuration of a positioning reference signal being used to indicate resource location information of the positioning reference signal; cell public channel configuration for performing the positioning measurement; valid time range indication information configured to indicate the valid time range of the positioning assistance information; and valid space range indication information configured to indicate the valid space range of the positioning assistance information.
