PURPOSE: A method for processing radio data in an interworking function interface rack is provided to reduce the load of a main processor by processing a protocol in a peripheral processor. CONSTITUTION: A peripheral processor checks a primitive from a firmware by checking periodically a memory(ST1). A primitive of the layer 2 is read from the memory and the primitive of the layer 2 is checked if the primitive is checked(ST2,ST3). A message of the layer 3 is extracted from the primitive of the layer 2 if the primitive of the layer 2 is an available primitive(ST4). An entity of an upper main processor is checked from the message of the layer 3(ST5). An upper signal is formed with the layer 3 if there is the entity of the upper main processor(ST6). The message is transmitted to a corresponding processor of the upper main processor(ST7). The peripheral processor checks the message from the main processor(ST8). The availability of the received message is checked(ST9). The message of the layer 3 is formed if the received message is the available signal(ST10). A primitive of L2 is formed by copying the message of the layer 3 in a data field region of an L2 primitive(ST11). The primitive is transmitted to a lower firmware(ST12).
