Communication system, base station apparatus, server apparatus, mobile station apparatus, and transmission data amount determining method

Base station equipment for use in a mobile communication system in which a mobile station apparatus communicates with a server apparatus by using a plurality of links relayed by a plurality of base station apparatus, respectively, 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 link relayed by said base station apparatus 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.

A server apparatus for use in a mobile communication system in which a mobile station apparatus communicates with a server apparatus by using a plurality of links relayed by a plurality of base station apparatus, respectively, said server apparatus comprising:

• transmittable data amount information acquiring means for acquiring transmittable data amount information representing amounts of data able to be transmitted from each of said base station apparatuses to said mobile station apparatus;
• and
• communication data transmitting means for transmitting communication data of amounts of transmission data corresponding to amounts of transmittable data represented by the transmittable data amount information to each of said links.

A mobile station apparatus for making a communication by using at least one of a plurality of links relayed by a plurality of base station apparatus, respectively, in a mobile communication system including said plurality of base station apparatus, said mobile station apparatus comprising:

• transmittable data amount information acquiring means for acquiring transmittable data amount information representing amounts of data which said mobile station apparatus is able to transmit through said links relayed by each of said base station apparatuses;
• and
• communication data transmitting means for transmitting communication data of amounts of transmission data corresponding to amounts of transmittable data represented by the transmittable data amount information to each of links.
