ABSTRACT:
A mobile station, i.e., mobile phone included in a cellular telephone system processes paging messages using a dual-port RAM memory connected between a signal processor (DSP) and a microprocessor (MCU). The paging message received and coded by the signal processor is transferred to the RAM memory, the identity number contained by the paging message is compared with the identity number of the microprocessor at the same time in the signal processor and only when they are congruent, the microprocessor is activated through a separate interrupt line. Because most paging messages are either empty messages or intended for other mobile stations, the microprocessor (MCU) can remain on as low a power level as possible during the paging of messages while the mobile station is in the stand-by state.
