ABSTRACT:
A method and system that enables a portable station within the personal handy phone system (PHS) to utilize the preamble field of the communication interface to contain extended common access channel field information while optimizing power consumption. The present invention can operate within a cell station of the PHS. The present invention empowers a portable station to identify the type of data contained within the preamble field. A predetermined number of data bits are extracted from the beginning of the preamble field of an incoming data frame received by a portable station. The present invention determines if the extracted data bits are identical to a predetermined data bit pattern. If the extracted data bits are identical to the data bit pattern, the portable station is directed to treat the data contained within the preamble field as the standardized preamble of the PHS by not storing it within memory and not performing a cyclic redundancy check (CRC) on it. If the data bits are not identical to the data bit pattern, the portable station treats the data contained within the preamble field as extended common access channel data by storing it within memory and performing a CRC on it. By enabling a portable station to identify the data within the preamble field, data storage and CRC are not performed on preamble data resulting in conservation of portable station power. Optimizing power consumption within a portable station is critical because it operates under limited battery power.
