COMMUNICATION APPARATUS, COMMUNICATION METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM

摘要

A first header compression table for compressing a message header is generated based on a first communication connection established between communication apparatuses. A message is transmitted from a communication apparatus to another communication apparatus based on the first communication connection, and a header of the message has been compressed based on the first header compression table. It is determined whether the first header compression table is used as a second header compression table for compressing a message header to be communicated based on a second communication connection which is different from the first communication connection and has been established between the communication apparatuses. The header of the message to be communicated based on the second communication connection is compressed using the first header compression table as the second header compression table in accordance with the determination.

主权项

1. A communication apparatus comprising:
a generation unit configured to generate a first header compression table for compressing a header portion of a message to be communicated based on a first communication connection established with another communication apparatus; a transmission unit configured to transmit, to the other communication apparatus based on the first communication connection established with the other communication apparatus, the message whose header portion has been compressed based on the first header compression table generated by the generation unit; a determination unit configured to determine whether the first header compression table is used as a second header compression table for compressing a header portion of a message to be communicated based on a second communication connection which is different from the first communication connection and has been established with the other communication apparatus; and a compression unit configured to compress the header portion of the message to be communicated based on the second communication connection using the first header compression table corresponding to the first communication connection as the second header compression table corresponding to the second communication connection in accordance with determination by the determination unit, wherein at least one of the generation unit, the transmission unit, the determination unit, or the compression unit is implemented using a processor.
