The multiple applications which the communication terminal, the communication system, available band presumption manner

摘要

PROBLEM TO BE SOLVED: To provide a communication terminal that estimates an available bandwidth while taking an effect of simultaneous use of a network by a plurality of applications into consideration even in such a case.;SOLUTION: A communication application means 111 achieves communication with a communication partner. A network transmission and reception means 113 is used in common by a plurality of applications using the network. An integrated band estimating means 115 acquires data communication information on data that the network transmitting and receiving means 113 receives from the communication partner during the execution of a plurality of applications. The integrated band estimating means 115 estimates an available band for a communication terminal 10 of the communication partner based upon the data communication information in a predetermined period.;COPYRIGHT: (C)2010,JPO&INPIT
