A mobile User Equipment (UE) saves power by ascertaining whether it is in a static environment. The UE's changeable state parameters (e.g., time and location) are compared with its historical changeable state data to determine whether a match exists. If the UE is in the static environment and the UE's changeable state presently matches the previously observed changeable state, then the UE repeatedly measures its radio environment at a first rate. If the UE is in the static environment and the UE's changeable state does not presently match the previously observed changeable state, then the UE repeatedly measures its radio environment at a second rate for a predetermined period of time, wherein the first rate is less than the second rate. If the UE is not in the static environment, then it repeatedly measures its radio environment at the second rate for an unrestricted amount of time.
