Abstract

The number of communication channels necessary for communication with a terminal is calculated by using type and volume of data to be transmitted. When calculated number of communication channels is one, a single communication channel is allocated based on quality information of a communication line to the terminal and, when calculated number of communication channels is more than one, then more than one communication channels are allocated based on the quality information. Allocation information used for notifying of allocated communication channels is generated based on virtual channels, which are defined in advance as channel units having a combination of a plurality of consecutive communication channels, and the allocation information is transmitted to the terminal.

Claims

1. A channel allocation notifying method with which a communication apparatus in a communication system allocates a communication channel to a terminal belonging to the communication apparatus and notifies the communication channel to the terminal, the channel allocation notifying method comprising:

a number-of-channel calculating step of calculating number of communication channels necessary for a communication with the terminal by using type and volume of data to be transmitted;

a channel allocating step 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

an allocation information generating step 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.
