ATM DATA RECEIVING METHOD BETWEEN PROCESSORS IN MOBILE COMMUNICATION BASE STATION SYSTEM

PURPOSE: An ATM(Asynchronous Transfer Mode) data receiving method between processors in mobile communication base station system is provided to not only transmit a large volume of ATM data successively but also process the ATM data rapidly and efficiently by using the advantages of a poling and interrupt methods. CONSTITUTION: A call processing processor starts a poling to a memory(S1). The processor discriminates whether an interrupt flag of ATM data within the flash memory exists(S2). If an interrupt flag of ATM data within the flash memory does not exist, the call processing processor reads a large volume of ATM data stored to the memory during the poling as much as the processing volume, simultaneously transmits the data and thereafter returns(S3). If an interrupt flag of ATM data within the flash memory exists, the call processing processor reads the newly inputted and stored ATM data together with the large volume of ATM data during the previous poling, simultaneously transmits the data to a modem and thereafter returns(S4).
