Communication System, Base Station Apparatus, Server Apparatus, Mobile Station Apparatus, and Transmission Data Amount Determining Method
First Claim
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.

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.
