INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Methods and techniques are described for initiating a periodic and triggered location in a target UE. After an LCS Client requests initiation of periodic and triggered location reporting from the UE, two intermediate responses are returned by a network. A first response indicates that the periodic and triggered location request has been received and accepted by the network. A second response indicates that periodic and triggered location has been activated in the UE. Additionally, a periodic and triggered location request may include a maximum event sampling interval and a maximum reporting interval and one or more location triggers. The maximum event sampling interval can limit UE power consumption and the maximum reporting interval can detect when periodic and triggered location is no longer active in a UE. The location triggers may include periodic reporting, reporting using area events or reporting based on UE motion. ## Claims ### Claim 1 A method at a first network entity of performing periodic and triggered location for a target user equipment, comprising: receiving from a second network entity a periodic and triggered location request for the target user equipment;
