Abstract

A mobile unit communication system, includes a mobile unit; and a base station. The mobile unit includes: a terminal transmit unit transmitting an upward data to the base station; a terminal receive unit receiving a downward data from the base station; and an upward data amount calculating unit calculating an upward data amount of the upward data. The base station includes: a base station receive unit receiving the upward data; a base station transmit unit transmitting the downward data to the mobile unit; and a detecting unit detecting the upward data amount. The base station allocates upward additional channels of the numbers corresponding to the upward data amount detected by the detecting unit in addition to a base channel to the mobile unit.

Claims

1. A mobile unit communication system comprising:

a mobile unit; and

a base station, and

wherein said mobile unit includes;

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 includes;

a base station receive unit receiving said upward data;

a base station transmit unit transmitting said downward data to said mobile unit; and

a detecting unit detecting said upward data amount, and

wherein said base station allocates upward additional channels of a number corresponding to said upward data amount detected by said detecting unit in addition to a base channel to said mobile unit,

wherein said mobile unit further includes a telegraphic message generating unit generating an upward and upward additional channel request telegraphic message to request to allocate said additional channels,

wherein said terminal transmit unit transmits said upward and upward additional channel request telegraphic message to said base station, and

wherein said base station includes a table in which the number of said additional channels is determined in reference to a number of remaining channels and said upward data amount.

2. The mobile unit communication system according to claim 1, wherein said additional channels are opened after said upward data is transmitted to said base station.

3. The mobile unit communication system according to claim 1, wherein said base station further includes an internet transmission reception unit connecting to the internet to receive said downward data from the internet, and

wherein said detecting unit detects a downward data amount of said downward data received from the internet.

4. The mobile unit communication system to claim 3, wherein said base station allocates downward additional channels allocated based on said downward data amount in addition to said base channel to said mobile unit.

5. A mobile unit communication system comprising:

a mobile unit; and

a base station, and

wherein said mobile unit includes;

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 includes;

a base station receive unit receiving said upward data;

a base station transmit unit transmitting said downward data to said mobile unit;

a detecting unit detecting said upward data amount; and

an internet transmission reception unit connecting to the internet to receive said downward data from the internet,

wherein said detecting unit detects a downward amount of said downward received from the internet,

wherein said base station allocates upward additional channels of a number corresponding to said upward data amount detected by said detecting unit in addition to a base channel to said mobile unit,

wherein said base station allocates downward allocation channels allocated based on said downward data amount in addition to said base channel to said mobile unit, and

wherein said base station includes a downward table in which a number of said downward additional channels is determined in reference to a number of remaining channels and said downward data amount.

6. The mobile unit communication system according to claim 5, wherein said mobile unit further includes a telegraphic message generating unit generating an upward and upward additional channel request telegraphic message to request to allocate said additional channels, and

wherein said terminal transmit unit transmits said upward and upward additional channel request telegraphic message to said base station.

7. The mobile unit communication system according to claim 6, wherein said base station includes an upward table in which the number of said additional channels is determined in reference to the number of remaining channels and said upward data amount.

8. The mobile unit communication system according to claim 7, wherein said downward table is a same as said upward table.

9. A mobile unit communication method, comprising:

(a) transmitting of a 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 a number 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;

(d) allocating of said base station downward channels of a number corresponding to a downward data amount of a downward data transmitted from said base station to said mobile unit in addition to a base channel, to said mobile unit, wherein the allocating step is performed by said base station referencing a table in which the number of said additional channels is determined in reference to a number of remaining channels and said downward data amount; and

(e) transmitting of said base station said downward data with said downward channels to said mobile unit.

10. The mobile unit communication method according to claim 9, wherein said step (b) is not performed when said upward data amount is equal to or less than a threshold.

11. The mobile unit communication method according to claim 9, wherein said step (d) is not performed when said downward data amount is equal to or less than a threshold.

12. 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;

an upward data amount calculating unit calculating an upward data amount of said upward data; and

a telegraphic message generating unit generating an upward and upward additional channel request telegraphic message to request to allocate additional channels,

wherein said base station allocates upward additional channels of a number corresponding to said upward data amount in addition to a base channel to said mobile unit,

wherein said terminal transmit unit transmits said upward and upward additional channel request telegraphic message to said base station, and

wherein said base station references a table in which the number of said additional channels is determined in reference to a number of remaining channels and said upward data amount.

13. The mobile unit communicating with a base station according to claim 12, wherein said additional channels are opened after said upward data is transmitted to said base station.

14. 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 mount of said upward data, and

wherein base station allocates upward additional channels of a number corresponding to said upward data amount in addition to a base channel to said mobile unit,

wherein said base station includes a table in which the number of said additional channels is determined in reference to a number of remaining channels and said upward data amount.
