Channel allocation notifying method, communication method, and communication apparatus
First Claim
1. 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 includingallocating 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, andallocating 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 includinggenerating allocation information based on a virtual channel that is set in advance and that represents a plurality of consecutive communication channels, the allocation information indicating an allocated communication channel to the terminal, andtransmitting the allocation information to the terminal,dividing usable communication channels into channel groups each including a plurality of communication channels, whereinthe allocation information includesa group bit for identifying the channel groups, anda channel bit that indicates an allocation status of a communication channel in each virtual channel.

Abstract
The number of communication channels necessary for communication with a terminal is calculated by using type and volume of data to be transmitted (Step S13). 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 (Step S14). 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 (Steps S15 and S16).

13. 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 a calculated number of communication channels is one, and the communication apparatus allocating more than one communication channel 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 based on a virtual channel that is set in advance and that represents a plurality of consecutive communication channels, the allocation information indicating an allocated communication channel to the terminal, and the communication apparatus transmitting the allocation information to the terminal; 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; and dividing usable communication channels into channel groups each including a plurality of communication channels, wherein the allocation information includes a group bit for identifying the channel groups, and a channel bit that indicates an allocation status of a communication channel in each virtual channel.

14. A communication apparatus that builds a communication system with a terminal belonging to the communication apparatus, the communication apparatus allocating a communication channel to the terminal, the communication apparatus comprising:
-
a microprocessor; a channel allocating unit, executed by the microprocessor, that calculates a number of communication channels necessary for a communication with the terminal by using type and volume of data to be transmitted, when the calculated number of communication channels is one, allocates a single communication channel to the terminal based on quality information of a communication line between the communication apparatus and the terminal, and when the calculated number of communication channels is more than one, allocates more than one communication channel to the terminal based on the quality information; an allocation information generating unit, executed by the microprocessor, that generates allocation information based on a virtual channel that is set in advance and that represents a plurality of consecutive communication channels, the allocation information indicating an allocated communication channel to the terminal; and a dividing unit that divides usable communication channels into channel groups each including a plurality of communication channels, wherein the allocation information includes a group bit for identifying the channel groups, and a channel bit that indicates an allocation status of a communication channel in each virtual channel.
