Document Type and Number:
WIPO Patent Application WO/2012/081083
Kind Code:
A1
Abstract:
The present invention has the objective of shortening acceptance processing time in order to improve the quality of transmittance. A frame transmission device of the present invention includes a transmission unit which transmits frames including a predetermined field value after modification consecutively a predetermined number of times if a modification has occurred in a value of a predetermined field of the frames. A frame reception device includes a reception unit for receiving the frames and an acceptance processing unit which identifies the predetermined field value in order to perform acceptance processing thereupon. In addition, the acceptance processing unit compares the received predetermined field value with an estimated value if the predetermined field value differs from the current accepted value, whereupon if the values match, the received predetermined field value is accepted, whereas if the values do not match, then if the same predetermined field value is received consecutively for the predetermined number of times, the predetermined field value is accepted.
