    [0017] A preferred embodiment of the present invention will be described herein below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. [0017]
    [0018] First, a description of the construction of a wireless telephone set in accordance with a preferred embodiment of the present invention will be made with reference to FIG. 1. [0018]
    [0019] Signals received by an antenna [0019] 101 are input by a receiving section 105 through a filter 103. The receiving section 105 down-converts and amplifies the input signals, and a demodulating section 107 demodulates the signals outputted by the receiving section 105 and outputs the signals to a signal-processing and control section 100. The signal-processing and control section 100 processes the signals inputted through a microphone and outputs the signals through a modulating section 113 to a transmitting section 111. Here, the transmitting section 111 outputs the signals to the antenna 101 by up-converting the frequency to a transmission frequency band and, amplifying and filtering the same. A phase lock loop 109 provides a local oscillating frequency to the transmitting section 111 and the receiving section 105, so as to convert the received signals or the transmitted signals into the desired frequency. On the other hand, the signal-processing and control section 100 controls the signal processing and data receipt/transmission within each section of the wireless telephone set, and outputs signals for controlling the electric power supply to each section of the wireless telephone set according to the conditions of the wireless telephone set and a mode selection.
    [0020] An operation of the wireless telephone set will be described hereinbelow in accordance with a preferred embodiment of the present invention with reference to FIGS. 1 and 2. [0020]
    [0021] The signal-processing and control section [0021] 100 detects whether or not any interrupting signals have been generated in step 200, e.g., when a call message or paging message has been received, an alarm timer has expired or a key is inputted by a key input section 119. The generation of interrupting signals signifies that signals have been generated requiring the controller to turn on a power supply serving each corresponding section of the wireless telephone set. Each section is periodically polled, preferably every 320 ms, for a short duration, preferably 10 ms, to detect the presence of interference signals.
    [0022] If any interrupting signals have been generated, the signal-processing and control section [0022] 100 changes a power control mode of the wireless telephone set into a user mode and turns on the power supply to corresponding sections of the wireless telephone set according to the generated interrupting signals in step 210. For example, when a user inputs a key in order to edit telephone numbers in the wireless telephone set, power is supplied to a display section 123 and the key input section 119. The user mode is processed according to the generated interrupting signals in step 220. The power consumed in the user mode is less than the power consumed in the conventional transmission condition and the power consumed in the receiving condition of a slot mode.
    [0023] The signal-processing and control section [0023] 100 detects whether or not the signals are being transmitted in step 230. To be specific, if the user has requested the transmission of signals, the signal-processing and control section 100 supplies power to the transmitting section 111 and the receiving section 105 in step 240, and performs transmitting operations in steps 240 and 250. Otherwise, the procedure returns to step 200.
    [0024] When no interrupting signals are generated in step [0024] 200, a slot mode is operated in step 270, and therefore a sleeping condition and a receiving condition are periodically repeated in step 270. Step 200 is also performed simultaneously.
    [0025] A description of the chronological variances of power consumption according to a preferred embodiment of the present invention will be made with reference to FIGS. 3[0025] a to 3 c.
    [0026] FIG. 3[0026] a is a graph illustrating chronological variances of the power consumption during the slot mode. The slot mode is divided into a sleeping condition and a receiving condition, and repeats the above conditions at regular intervals. As shown in the graph of FIG. 3a, less power is consumed in the sleeping condition than in the receiving condition since power is supplied to only the sections necessary for control during the sleeping condition.
    [0027] FIG. 3[0027] b is a graph illustrating power consumption variations during a conventional mode. Referring to FIG. 3b, the supplied power is regularly consumed.
    [0028] FIG. 3[0028] c is a graph illustrating power consumption variations in accordance with the preferred embodiment of the present invention. Referring to FIG. 3c, the interrupting signals are generated in step 200 in the slot mode or the control mode, thereby setting the wireless telephone set into a user mode in step 210. When the receiving condition is entered from either the user mode or the slot mode, the power is supplied to the receiving section 105 to perform the receiving operation. While in the user mode, however, less power is consumed than while in the slot mode. In other words, according to a preferred embodiment of the present invention, the user mode is added so as to minutely control the power in the wireless telephone set. For example, in a conventional telephone set when a user inputs a key while in the slot mode, the same amount of power is consumed as when in the receiving condition of the slot mode. However, according to the preferred embodiment of the present invention, the power is supplied to only the sections necessary for operations according to generation of the interrupting signals, thereby resulting in a reduction of the overall power consumption as shown in the graph of FIG. 3c. On the other hand, if the user mode is terminated, and there is a request for the transmission of signals, the power consumption consequently increases to that of the conventional telephone set as shown in FIG. 3c. After the transmission operation is terminated, the slot mode is again operated.
    [0029] Although the receiving condition generated by receiving the call messages is not described above, a similar operation to that of the transmission condition is applicable to that case, as is evident. [0029]
    [0030] Another preferred embodiment of the present invention is described herein below with reference to FIGS. 4 and 5. [0030]
    [0031] FIG. 4 is a block diagram illustrating the construction of a wireless telephone set, which is similar to that of the wireless telephone set in FIG. 1. Referring to FIG. 4, additional hardware is added for controlling the power supply to the receiving section [0031] 105. The power supply to the receiving section 105 is controlled by logically adding slot mode control signals outputted by a signal-processing section 100 and transmitting section control signals 129 by means of an OR gate 801. To be specific, whenever the signals for turning-on the power supply are generated in the transmitting section 111 or the slot mode, the power is turned on.
    [0032] With reference also to FIG. 5, an operation of the preferred embodiment of FIG. 4 according to the present invention will be described. If the signals for turning-on the electric power supply to the transmitting section [0032] 111 is detected in step 500, the receiving section 105 is turned on and the receiving operation is performed in step 520. Otherwise, the phone detects whether or not the slot mode is under a receiving condition in step 510. If the slot mode is under a receiving condition, the receiving section 105 is turned on and the receiving operation is performed in step 520. If not, the procedure returns to step 500.
    [0033] As described above, the present invention provides an advantage of enhancing the available time for using a wireless telephone set by discriminating the control of the power supply to the wireless telephone set in accordance with the modes. [0033]
    [0034] While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
