Title:
COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP3949022
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform high quality data transfer control efficiently without using interruption processing by separating apparatus from each other thereby imparting flexibility to system configuration.
SOLUTION: A data link processing section 12 transfers data by delivering a data transfer request upon receiving a transfer response or performs processing for receiving data. A serial transfer section 14 on the communication processing side performs serial transfer through a cable C. When data is transmitted to the air, a transfer repeating section 22 generates a transfer instruction by receiving the data transfer request and returns a transfer response if possible. When data is transmitted to the air, a transfer control section 23 transfers data to a relevant slot on a transmission frame based on the transfer instruction and generates a wait when the data transfer requests are generated continuously. A frame transmitting/receiving section 24 performs assembling/disassembling of a frame and radio transmission/reception processing. A serial transfer section 21 on the radio processing section performs serial transfer through the cable C.
