Mobile unit communication system and a mobile unit communication method that can increase the efficiency of an assignment of a channel of a communication in which a data having a large data amount is transmitted at a high speed

A mobile unit communication method, comprising:

• (a) transmitting of an mobile unit an upward data amount of an upward data transmitted from said mobile unit to a base station, to said base station;
• (b) allocating of said base station upward channels of the numbers corresponding to said upward data amount in addition to a base channel to said mobile unit;
• and
• (c) transmitting of said mobile unit said upward data with said upward channels to said base station.

A mobile unit communicating with a base station, comprising:

• a terminal transmit unit transmitting an upward data to said base station;
• a terminal receive unit receiving a downward data from said base station;
• and
• an upward data amount calculating unit calculating an upward data amount of said upward data, and
• wherein said base station detects said upward data amount, and
• wherein said base station allocates upward additional channels of the numbers corresponding to said upward data amount in addition to a base channel to said mobile unit.

A base station communicating with a mobile unit, comprising:

• a base station receive unit receiving an upward data transmitted from said mobile unit;
• a base station transmit unit transmitting a downward data to said mobile unit;
• and
• a detecting unit detecting an upward data amount of said upward data, and
• wherein said base station allocates upward additional channels of the numbers corresponding to said upward data amount in addition to a base channel to said mobile unit.
