Patent ID: 7099679

Claim:
A method comprising: storing digital samples of a signal received by a mobile communication station in standby mode, said digital samples including data from a base communication station to said mobile communication station, said data indicating whether a message to said mobile communication station is forthcoming; deactivating at least part of a receive path of said mobile communication station; processing said stored samples; and deciding whether to enable said mobile communication station to receive said message, wherein said processing includes: searching for multipaths within said signal; and estimating whether said stored samples are sufficient to enable reliable decoding of said data, wherein said estimating comprises: estimating a plurality of signal power values corresponding to a plurality of found multipaths, respectively; estimating a plurality of noise-and-interference power values corresponding to said plurality of found multipaths, respectively; determining a ratio value corresponding to a plurality of ratios between said plurality of signal power values and said plurality of noise-and-interference power values, respectively; and comparing said ratio value to a predetermined value.
