Abstract

PROBLEM TO BE SOLVED: To suppress the transmission of a radio carrier to a base station at the time of a call by means of the misoperation of a subscriber, to prevent the occurrence of wasteful traffic and to effectively use radio resource in the radio telephone system such as a portable telephone set making the call by means of dial input after off-hooking. SOLUTION: An off-hooking recognition means 61 recognizes off-hooking by means of a subscriber operation. A timer (time limit means 62) is started by the off-hooking and time which is previously set is clocked. A selection signal reception/confirmation means 63 confirms the input of a selection signal for calling a callee and a judgment means 64 detects whether the selection signal is received or not within a period of time which is set. When the selection signal is detected within the period of time which is set, the radio carrier for the base station is transmitted from a carrier transmission control means 65 to a radio part 2. When the selection signal is not detected within the period of time which is set, the transmission of the radio carrier is suppressed.

2. Description of the Related Art Conventionally, this type of wireless telephone device has been used as a subscriber terminal device for mobile communication in a wireless telephone system. When a subscriber makes a call, he / she first goes off-hook using a call button or the like on the wireless telephone device, hears a dial tone that allows dial entry, and continues to input the telephone number of the other subscriber. Usually, this calling method is called split calling. In the wireless telephone device to which this divided transmission is applied, when the off-hook state due to the subscriber operation is detected, the wireless carrier is immediately transmitted to the base station, wireless communication is performed with the corresponding base station, and the base station communicates with the other party through the exchange. You are connected to the local telephone and are making a call.

[0003]

As described above, in this conventional radio telephone apparatus to which split calling is applied, as soon as an off-hook state is detected, a radio carrier is transmitted to a base station and communication with the base station is started. doing. Therefore,
Even if the subscriber accidentally presses the call button without intention to make a call, an unnecessary radio carrier is sent to the base station, and the communication between the radio telephone device and the base station is lost. Useless traffic occurs.

[0004] It is an object of the present invention to suppress the transmission of radio carriers to the base station when a call is made due to erroneous operation of a subscriber, to prevent the occurrence of useless traffic and to use radio resources effectively. An object of the present invention is to provide a wireless telephone device and a call connection method thereof.

SUMMARY OF THE INVENTION A radio telephone apparatus according to the present invention is a radio telephone apparatus in which a connection with a base station in a radio telephone system is dialed after off-hook and then inputted through a radio line. Off-hook recognizing means for recognizing off-hook, time limit means for activating the pre-set time by recognizing the off-hook, selection signal reception confirming means for confirming input of a selection signal for calling the called party, Determining means for detecting whether or not the selection signal is received within a set time;
When reception of the selection signal is detected within a set time by the determination unit, transmission of a wireless carrier to the base station is instructed.When reception of the selection signal is not detected within the set time, transmission of the wireless carrier is performed. And carrier transmission control means for suppressing.

In addition, the calling connection method of the present invention recognizes off-hook by a subscriber operation of the wireless telephone device when dialing out from the wireless telephone device to the base station in the wireless telephone system after dialing out and calling. Then, a timer is started by this off-hook and a preset time is counted, and it is determined whether or not the selection signal for calling the called party has been input within the set time, and the detection is performed. When the selection signal is detected within the time, the wireless carrier is transmitted to the base station, and when the selection signal is not detected within the set time, the transmission of the wireless carrier is suppressed.

Next, the present invention will be described with reference to the drawings.

Referring to FIG. 1 showing an embodiment of the present invention, a simplified portable telephone (Person) to which so-called split calling is applied, which allows dial input after off-hook.
A wireless telephone device used for an alHandyphone System (PHS) or the like includes an antenna 1, a wireless unit 2 for performing wireless communication with a base station (not shown) via the antenna 1, and a program for operating the device. A ROM 3, a RAM 4 for temporarily storing data necessary for executing the program, an EEPROM 5 for electrically writing and erasing various setting data, a control unit 6 for controlling the entire apparatus, a display unit 7, , A keyboard 8 for performing operations such as dial input, a microphone 9, and a speaker 10.

Next, a detailed configuration of the control unit 6 according to the present invention will be described. The control unit 6 includes an off-hook recognizing means 61 for recognizing off-hook by a subscriber's operation input in addition to a control for a normal connection call, and a time-measuring means 62 for activating the pre-set time by measuring the off-hook. A selection signal reception confirming means 63 for confirming the input of a selection signal for calling the called party; a decision means 64 for detecting whether or not the selection signal has been received within a set time; Carrier transmission control means for instructing transmission of a wireless carrier to the base station when the selection signal is detected by the determination means 64 and for suppressing transmission of the wireless carrier to the base station when the selection signal is not detected. 65.

FIG. 2 is a flowchart showing a processing procedure and an operation state of an embodiment of a call connection method for a wireless telephone device according to the present invention. The state transition of the wireless telephone device at the time of calling will be described below with reference to FIGS. The wireless telephone device is in a standby state (S1) while being synchronized with the logical control channel from the base station. In this state S1, when the subscriber presses an off-hook key (not shown) for calling the keyboard 8, the off-hook recognition means 61 of the control unit 6 recognizes this and activates a time limit means (timer) 62. Then, the timer 62 starts counting a preset time (S2), outputs a dial tone to the speaker 10 to urge the subscriber to input a selection signal (dial key information) (S3), and waits for dial key input. Transition is made (S4).

In state S4, the selection signal reception confirming means 63 confirms the dial key input, and the judging means 64 detects before the timer times out, that is, when the dial key input is detected within the set time, Assuming that the subscriber has a calling intention, the timer stops counting (S5),
The output of the dial tone is stopped (S6), the carrier transmission control means 65 instructs the wireless unit 2 to transmit a wireless carrier to the base station, and transitions to a calling state (S7).

In this case, the number of digits to be monitored for the selection signal by dial input for confirming the call intention after off-hook is usually set to one digit and set from the keyboard 8, but this number is set to three or ten digits. Then, the calling state may be determined when it becomes more certain.

Next, in state S4, while the selection signal reception confirming means 63 is confirming the dial key input, the determining means 64 detects that the timer has timed out, that is, that there has been no dial key input within the set time. Then, assuming that the subscriber has no intention to call, the timer stops counting (S8), starts outputting the busy tone, and informs the subscriber that there was an erroneous operation that the off-hook button was pressed by mistake. A notification is sent (S9), and a transition is made to an on-hook input wait for returning to the normal standby state (S10). If the subscriber notices this erroneous operation and presses an on-hook key (not shown), the output of the busy tone is stopped (S
11) Return to state S1. In this case, since the dial key input is not detected, the carrier transmission control unit 65 does not issue a carrier transmission instruction to the radio unit 2 and suppresses unnecessary radio carrier transmission.

On the other hand, in the state S4, if the selection signal reception confirmation means 63 is confirming the dial key input and the subscriber notices an erroneous operation and presses the on-hook key before the timer times out, the decision means 64 Deems that the subscriber does not intend to make a call, stops the timer (S12), stops outputting the dial tone (S13), and returns to the state S1. Also in this case, no dial key input was detected, so
No carrier transmission instruction is performed, and useless transmission of wireless carriers is suppressed.

[0015]

As described above, according to the present invention, when a call is made by dialing into a base station in a wireless telephone system after off-hook from the wireless telephone device and making a call, the off-hook operation by the subscriber of the wireless telephone device is performed. Recognize, start a timer by this off-hook, measure a preset time, determine whether or not the selection signal input for calling the called party has been made within the set time, and detect
When the selection signal is detected within the set time, the wireless carrier is transmitted to the base station, and when the selection signal is not detected within the set time, the transmission of the wireless carrier is suppressed, so that the useless radio carrier is suppressed. Is no longer transmitted, and wasteful traffic is prevented from being generated, and wireless resources can be effectively used.
