Claim Text:
1. A method implemented by a machine to machine (M2M) terminal for signal measurement in a communication system, the method comprising: determining whether a current subframe corresponds to a measurement period; measuring, when the current subframe corresponds to the measurement period, a serving cell signal; filtering the measured serving cell signal based on a particular ratio of the measured serving cell signal and a previously measured signal; determining whether a current measurement mode is a normal scan mode or a short scan mode to measure the serving cell signal more frequently than the normal scan mode; determining, when the current measurement mode is the normal scan mode, whether the measured serving cell signal is less than a predetermined low signal threshold; and switching, when the measured serving cell signal is less than the predetermined low signal threshold, the current measurement mode to the short scan mode.
