Abstract
In a communication apparatus communicating with a plurality of communication stations in a communication network system by the use of a broadcast frame, a local processor is included in addition to a main processor to preliminarily judge whether or not the broadcast frame is to be received by the communication apparatus. In the local processor, when reception conditions are not satisfied, the broadcast frame is rejected. When the conditions are satisfied, the broadcast frame is received. Such conditions are used as a judgement criterion in the broadcast frame and are compared with a broadcast reference signal in the local processor to select the broadcast frame. The main processor may process only the selected broadcast frame rather than all broadcast frames. Thus, resulting in a reduction of jobs.
