Patent ID: 8285287

Claim:
A wireless communication terminal comprising: a switching section for switching between a first communication system in which an upper limit value of a transmission rate varies and a second communication system; a reception section for receiving an information indicating the upper limit value of the transmission rate in the first communication system, from a base station; a comparison section for making a comparison between the upper limit value received by the reception section and a predetermined reference value, either at a communication start time or during communication with the base station in the first communication system; a control section for performing switching control of the switching section so as to perform communication in the second communication system when the upper limit value is lower than the reference value as a result of the comparison by the comparison section; and a derivation section for deriving a remaining amount of data to be transmitted in the first communication system, wherein the control section performs the switching control to the second communication system when the upper limit value is lower than the reference value as the result of the comparison by the comparison section, and only when the remaining data amount derived by the derivation section is larger than a predetermined amount.
