Channel allocation notifying method, communication method, and communication apparatus

A method of allocating a communication channel to a terminal belonging to a communication apparatus and notifying the communication channel to the terminal, the method comprising:

• number-of-channel calculating including calculating number of communication channels necessary for a communication with the terminal by using type and volume of data to be transmitted;
• channel allocating including
• allocating a single communication channel to the terminal based on quality information of a communication line between the communication apparatus and the terminal when calculated number of communication channels is one, and
• allocating more than one communication channels to the terminal based on the quality information when the calculated number of communication channels is more than one;
• and
• allocation information generating including
• generating allocation information for notifying an allocated communication channel to the terminal based on a virtual channel that is set in advance as a unit of channel by combining a plurality of consecutive communication channels, and
• transmitting the allocation information to the terminal.

A communication method between a communication apparatus in a communication system and a terminal belonging to the communication apparatus when the communication apparatus allocates a communication channel to the terminal and notifies the communication channel to the terminal, the communication method comprising:

• number-of-channel calculating including the communication apparatus calculating number of communication channels necessary for a communication with the terminal by using type and volume of data to be transmitted;
• channel allocating including
• the communication apparatus allocating a single communication channel to the terminal based on quality information of a communication line between the communication apparatus and the terminal when calculated number of communication channels is one, and
• the communication apparatus allocating more than one communication channels to the terminal based on the quality information when the calculated number of communication channels is more than one;
• allocation information generating including
• the communication apparatus generating allocation information for notifying an allocated communication channel to the terminal based on a virtual channel that is set in advance as a unit of channel by combining a plurality of consecutive communication channels, and
• the communication apparatus transmitting the allocation information to the terminal;
• and
• an allocated channel calculating including the terminal obtaining a communication channel allocated to the terminal by performing a reverse procedure to an allocation information generating process on received allocation information.
