ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a radio apparatus capable of downloading predetermined data such as music data from a download site through a radio communication line.
Heretofore, there is proposed a radio apparatus such as a portable telephone capable of downloading music data from a server of a download site through a radio communication line. In this case, the music data thus downloaded may be written in a detachable recording medium, for example, and reproduced therefrom after the downloading.
The above-mentioned radio apparatus may use a battery of a small capacity as a rechargeable battery in accordance with the current in which radio apparatus become more and more compact in size and light in weight. As a result, it is frequently observed that a voltage value of a battery becomes smaller than a threshold value necessary for writing data in a recording medium during music data of a certain piece of music is downloaded. In that case, the downloading should be interrupted, and music data should be downloaded over again from the beginning of the music after the battery was charged or the battery was replaced with a charged battery. Consequently, a communication charge is wasted unavoidably.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a radio apparatus which can be miniaturized and made light in weight by using a battery of a small capacity and in which a communication charge can be avoided from being wasted.
According to an aspect of the present invention, there is provided a radio apparatus powered by a rechargeable battery and which is capable of downloading predetermined data through a radio line. This radio apparatus is comprised of a data transmission request means for requesting the download site to transmit said predetermined data, a data reception means for receiving the predetermined data transmitted from the download site, a data recording means for sequentially writing the predetermined data received at the data reception means in a recording medium, a voltage detection means for detecting a voltage value of the battery, a write interrupt control means for interrupting the data recording means to write the predetermined data when a voltage value detected by the voltage detection means becomes smaller than a threshold value required by the data recording means to write data in the recording medium, line disconnection means for disconnecting a line between the radio apparatus and the download site when the writing of the predetermined data is interrupted, a memory means for memorizing a telephone number of the download site and information of the predetermined data the writing of which was interrupted, a line connection means for connecting a line between the radio apparatus and the download site by using the download site telephone number memorized in the memory means when the voltage detected by the voltage detection means becomes greater than the threshold value after the line was disconnected, a data resend request means for requesting the download site to transmit remaining data of the predetermined data the writing of which was interrupted by informing the download site of information of the predetermined data memorized in the memory means after the line was connected and a resume control means for controlling the data recording means such that the recording means writes the remaining data received at the data reception means in the recording medium.
In this invention, the download site is requested to transmit predetermined data such as music data of a certain piece of music, and the predetermined data transmitted from the download site is sequentially written in a recording medium such as an IC memory. In this case, when a voltage value of a battery becomes smaller than a threshold value required by the data recording means to write data in the recording medium, the writing is interrupted, and a line between the radio apparatus and the download site is disconnected temporarily. When an apparatus body, for example, is placed on a charging stand so that the voltage of the battery may become greater than the threshold value, the downloading is resumed automatically, and remaining data of the predetermined data is sequentially written in the recording medium.
When the line between the radio apparatus and the download site is disconnected temporarily, the download site telephone number and the information of the predetermined data the writing of which was interrupted are memorized in the memory section, and are used to resume the download processing which will be executed if other recording medium is loaded. In this case, the download site telephone number is used to connect the line between the radio apparatus and the download site. The information of the predetermined data (information of title of music and time and position in and at which the writing was interrupted, or the like if the predetermined data is music data) is used as notifying information that may request the download site to transmit only the remaining data of the predetermined data the writing of which was interrupted.
