Abstract

It is advantageous for present invention to suitably determine amounts of transmission data for links in a multilink communication. In a mobile communication system (10) for making a multilink communication through which a communication is performed by using a plurality of links relayed by a plurality of base station apparatus (30), respectively, each of the base station apparatuses (30) acquire transmittable data amount information representing amounts of data able to be transmitted through the respective links by a mobile station apparatus (20) or a server apparatus (40), and the mobile station apparatus (20) or the server apparatus (40) determines amounts of transmission data to be transmitted to the respective links in correspondence to the transmittable data amount information, and transmits communication data of amounts of data corresponding to the amounts of transmission data determined to the respective links.

Claims

1. A communication system for making a multilink communication by using a plurality of links, each of the links partially includes a radio link, said communication system comprising:

transmittable data amount information acquiring means for acquiring transmittable data amount information representing amounts of data able to be transmitted through the radio link included in each of said links, based on radio band information on the radio link;

distribution rate determining means for determining rates of distribution of communication data to the respective links, based on amounts of transmittable data represented by the transmittable data amount information; and

communication data transmitting means for transmitting communication data of amounts corresponding to the determined rates of distribution to each of said links.

2-9. -9. (canceled)

10. A base station apparatus relaying one of a plurality of links used for a communication made by a mobile station apparatus and a server apparatus wherein a part between the base station apparatus and the mobile station apparatus in the link is a radio link, and said base station apparatus comprising:

transmittable data amount information acquiring means for acquiring transmittable data amount information representing an amount of data able to be transmitted through the radio link from said base station apparatus to said mobile station apparatus; and

transmittable data amount information transmitting means for transmitting the transmittable data amount information to said server apparatus or said mobile station apparatus.

11. A server apparatus communicating with a mobile station apparatus by using a plurality of links relayed by a plurality of base station apparatus, respectively, wherein a part between each of the base station apparatuses and the mobile station apparatuses in each of the links is a radio link, said server apparatus comprising:

transmittable data amount information acquiring means for acquiring transmittable data amount information representing amounts of data able to be transmitted through each radio link from each of said base station apparatuses to said mobile station apparatus;

distribution rate determining means for determining rates of distribution of communication data to the respective links, based on amounts of transmittable data represented by the transmittable data amount information; and

communication data transmitting means for transmitting communication data of amounts corresponding to the determined rates of distribution to each of said links.

12. A mobile station apparatus for making a communication by using a plurality of links relayed by a plurality of base station apparatuses, respectively, wherein a part between each of the base station apparatuses and the mobile station apparatus in each of the links is a radio link, said mobile station apparatus comprising:

transmittable data amount information acquiring means for acquiring transmittable data amount information representing amounts of data able to be transmitted through each radio link from the mobile station apparatus to each of said base station apparatuses;

distribution rate determining means for determining rates of distribution of communication data to the respective links, based on amounts of transmittable data represented by the transmittable data amount information; and

communication data transmitting means for transmitting communication data of amounts corresponding to the determined rates of distribution to each of said links.

13. A transmission data amount determining method of determining an amount of transmission data for each link in a communication system for making a multilink communication by using a plurality of links, each of the links partially includes a radio link, said transmission data amount determining method comprising:

a transmittable data amount information acquisition step of acquiring transmittable data amount information representing amounts of data able to be transmitted through the radio link included in each of said links, based on radio band information on the radio link;

a distribution rate determination step of determining rates of distribution of transmission data to the respective links, based on amounts of transmittable data represented by the transmittable data amount information; and

a data transmission step of transmitting transmission data of amounts corresponding to the determined rates of distribution to each of said links.
