judging means for judging whether communication quality of the second channel between the mobile terminal and the base station end by said communication means is not less than a preset predetermined communication quality of the second channel between the mobile terminal and the base station end; and
control means, when said judging means judges that the communication quality of the second channel between the mobile terminal and the base station end is under the predetermined communication quality of the second channel between the mobile terminal and the base station end, for controlling said free time generation processing means to generate the free time interval and for controlling said communication means to temporarily stop data communication during the free time interval, andwhen said judging means judges that the communication quality of the second channel between the mobile terminal and the base station end is not less than the predetermined communication quality of the second channel between the mobile terminal and the base station end, for controlling said free time generation processing means not to generate the free time interval and also for controlling said communication means to continue performing data communication,wherein the free time intervals are not generated when communication quality is not less than the preset predetermined communication quality of the second channel between the mobile terminal and the base station end.

Abstract
In a case of being judged that a compressed mode is applied in a mobile terminal, if it is judged that reception quality during data communication is favorable, gap intervals are not created by passing through a processing of gap interval creation. Further, if the data communication over the HS-DSCH is performed, the data communication over the HS-DSCH is continued. This prevents degradation of data transmission rate over a channel for high speed data transmission service, in the presence of a mobile terminal in a favorable reception quality area.
