Abstract

PURPOSE:To smoothly establish a human interface and to enable efficient communication by turning on/off a busy tone and a back light part for liquid crystal display to a receiver when it is detected that a radio line is blocked in the case of service activation with the transmission of radio waves. CONSTITUTION:This telephone set is provided with a liquid crystal display part 305 to display operation designating data inputted from an operation button part 304 of the own set and data showing the state of the own set, and a control part 303 provided with a block detecting means to catch transmission and reception in the case of the service activation and to detect that the radio line for establishing a line depending on radio waves to a base station is blocked, and an audible display means to generate the busy tone to the receiver of the own set and further, a back light part 306 of the liquid crystal display part 305 is provided. In this case, when the radio line is blocked in the case of the service activation, it is visibly displayed by controlling the ON/OFF of the back light part 306 in addition to the audible busy tone.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless telephone equipped with a liquid crystal display.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a radio telephone of this type has an antenna section 401 for transmitting and receiving radio waves.
And a radio circuit unit 402 including a baseband circuit for modulating and demodulating radio waves transmitted and received by an antenna, transmitting and receiving control data, a microphone, a speaker, and the like, and inputting and outputting control commands to and from the radio circuit unit 402. A control unit 403 that controls the entire wireless telephone, and a control unit 40
An operation button section 304 including a numeric keypad connected to 3 for specifying an operation of the wireless telephone and a function button for a call and the like, and operation specification data etc. input from the operation button section 404 are input and displayed according to the specification of the control section 403. It is composed of a liquid crystal display unit 405 that displays a status. The control when the transmission operation is performed in the conventional example having such a configuration will be described with reference to the flowchart shown in FIG. This control is performed by the control unit 403 (the operation by the operator is omitted in the flowchart of FIG. 5). When the operator presses the call button, etc., the "calling service" is started, and the wireless line blockage is confirmed when this service is started (phase A). If there is no line blockage in this phase A operation, the base Preparations are made to send a "call command" to the station connection device (phase B ... Normal sequence). When the line blockage is detected in the phase A operation, the timer value for transmitting the line blockage tone (busy tone) to the handset is set in preparation for displaying that the line blockage is present (phase C1) and the busy tone is transmitted. Start (Phase C2), and if it detects that a sending stop operation has been performed during sending, or if the preset timer value overflows, the sending of the busy tone is stopped (Phase C3), and the initial state (standby) State). Phase C2 at this time
Then, it was audibly displayed with a busy tone that the line was blocked, and the busy tone was controlled so as to be transmitted from the handset.

[0003]

In such a conventional example, when the wireless line is blocked when a service such as transmission is started, an audible sound indicating that the wireless line is in use (closed) is displayed continuously or intermittently. Is displayed by sending it as a busy tone to the handset, etc., so each time the operator wants to confirm whether or not it is in use during the operation of the function key or numeric keypad, he / she should place the handset directly on his / her ear. It has the drawback that it cannot provide efficient communication.

The present invention eliminates such drawbacks, and an object of the present invention is to provide a wireless telephone having a human interface that functions smoothly when a wireless line blockage is detected.

[0005]

According to the present invention, there is provided a liquid crystal display section for displaying data including operation designation data inputted from an operation button section of the own machine and data indicating a state of the own machine,
Blocking detection means that detects when the wireless line that should be captured and establishes a line by radio waves with the base station during use of services including outgoing and incoming calls is in use and blocked state In a wireless telephone having a control unit including an auditory display means for generating a busy tone in its own handset, a backlight unit optically transmitting the liquid crystal display unit is provided, and the control unit is the blocking unit. It is characterized in that it includes a visual display means for controlling blinking of the backlight portion in response to detection of clogging of the detection means.

[0006]

[Function] In addition to the occurrence of a busy tone to the handset to display the line blockage when the line blockage is detected at the time of starting the service accompanied by the emission of the radio wave, the operator turns on the backlight part of the liquid crystal display to blink the operator. Notify.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a configuration example of a wireless telephone service system using the wireless telephone according to the present invention. As shown in FIG. 2, the wireless telephone service system of this application example includes a base station connection device 200 and a base station connection device 20 which are connected to the exchange 100 via a telephone line (101 to 10N).
0 and a wireless telephone 300 that connects to 0 via a wireless line. FIG. 1 is a block diagram showing an embodiment of the wireless telephone 300 in FIG. As shown in FIG. 2, the wireless telephone 300 includes an antenna unit 301 that is commonly used for transmission / reception of radio waves, a modulation / demodulation of radio waves, transmission / reception of control data, a call / control base such as a transmitter and receiver The wireless circuit section 302 including the band circuit, the operation button section 304 including the function buttons such as ten keys for dial operation, call, speed dial, one-touch dial, redial, etc. Liquid crystal display section 30 for displaying a plurality of digits of key information and the state of the wireless telephone 300.
