Title:
CODING/DECODING COMMUNICATION METHOD AND EQUIPMENT THEREOF
Document Type and Number:
Japanese Patent JP3492639
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable a voice communication with high quality according to the result of reserving a plurality of communication channels when making a high speed communication using a plurality of communication channels.
SOLUTION: In a communication channel reserving phase 311, a communication terminals on an originator side and an receiver side perform call-setting by a communication channel reserving process in a communication network. In a subsequent communication speed confirming/coding pattern determining phase S12, after the communication channel shifts to a communication state by the phase S11, the number of the communication channels reserved by the terminals on the originator side and the receiver side is confirmed, and a coding pattern is determined based on the confirmation of the number of the communication channels. In a communication phase S13 thereafter, a coding/decoding a communication process is performed to match a communication speed based on the result of determining the coding pattern, and a voice communication is executed.
