-2000 ATM cell router in IMT-2000 asynchronous base station

摘要

The present invention provides an ATM cell router (ACR) of an IMT-2000 asynchronous base station system. The present invention provides an apparatus for performing CDMA channel-related functions in an asynchronous base station system, and performs ATM cell-based data transmission and reception within a base station. To configure the ATM cell routing function, the communication function with the control station, the radio frequency (RF) processing device, and the ATM communication function with the outside, the ACR is configured as CRCA, CSRA. In other words, AEIA is implemented by redundancy. Thus, data transmission and reception inside an asynchronous base station is routed in the form of an ATM cell, so that when the IMT-2000 control station and this asynchronous base station interwork, the system load caused by the type conversion between the existing packet data and the ATM cell is eliminated, The communication path is handled in an Asynchronous Transfer Mode (ATM) scheme, thereby improving system performance.
