Abstract

PURPOSE:To attain the hooking operation simply in an optional timing by closing a line relay when a base station receives an off-hook signal at calling so as to bring the state into a talking state (off-hook state) and opening the line relay only while the off-hook signal is received in the talking state. CONSTITUTION:A control section 13 of a mobile station 1 has a state storage section storing whether the state is in the talking state (off-hook state) or not. When an off-hook switch 14 is depressed while the state storage part is in the non-talking state, said state storage part is set to the talking state. On the other hand, a control part 23 of a base station 2 has a state storage part storing whether the state is in the talking state or not. When the state storage part represents the non-talking state and the signal detection part 22 detects the off-hook signal, the control part 23 closes the line relay 25 to set the said state storage part into the talking state. When the state storage part represents the talking state and the signal detection part 22 detects the off-hook signal, while the control part 23 detects the off-hook signal, the line relay 25 is opened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a radio telephone device, and particularly to a radio telephone device in which a mobile station has separate off-hook switches and on-hook switches.

Generally, there is only one hook switch installed in the mobile station of a wireless telephone device, and when the handset is placed on the base terminal, the hook switch is turned off and the fourth hook state is set.When the handset is lifted up, the hook switch is switched off. ga゛′
It becomes a Zeon hook state.Also.

Using a hook switch with a slide switch.

Depending on the state of the slide switch, there are some that are in the on-hook or off-hook state.

In recent years, some mobile stations have separate off-hook switches and on-hook switches.

[Conventional technology]

Conventionally, this type of mobile station has an off-hook switch and an on-hook switch in a radio telephone device.

Regardless of whether the mobile station is making a call or is in a conversation state, when the off-hook switch is pressed, the mobile station sends an off-hook signal for a predetermined period of time, and when the on-hook switch is pressed, the mobile station sends an on-hook signal for a predetermined period of time and then sends a call-end signal. When the base station receives an off-hook signal, it connects the line relay, and when it receives an on-hook signal and a call-end signal, it disconnects the line relay.In other words, when the on-hook switch is pressed, the base station switches to the off-hook state. When you press the on-hook switch, it becomes on-hook.

[Problem that the invention seeks to solve]

However, with the above configuration, when performing a hooking operation when attempting to receive a service such as a call waiting service, the on-hook switch must be turned on to maintain the on-hook state for a predetermined period of time (for example, 0.5 seconds to 1 second). It is necessary to press the off-hook switch a predetermined time after pressing the button, which has the disadvantage that the hooking operation becomes complicated.

[Means and effects for solving the problems] The wireless telephone device according to the present invention includes a base station connected to a wired telephone line,
The base station comprises a mobile station that can be wirelessly connected to the base station, the mobile station having an on-hook switch, an off-hook switch, and means for wirelessly transmitting to the base station, and the base station.

A wireless telephone device comprising means for receiving a signal wirelessly transmitted from the mobile station, and a line relay for connecting or disconnecting the wired telephone line.

The mobile station includes a transmission signal control means that detects that the off-hook switch or the on-hook switch is pressed and changes the signal to be transmitted to the wireless transmission means depending on whether a call is being made or a conversation is being made. and the base station detects a received signal from the receiving means and controls the line relay by changing the connection or disconnection operation depending on whether a call is being made or a call is being made. It is characterized by having means.

[Effect]

According to the above configuration, when the mobile station presses the off-hook switch when making a call, it sends an off-hook signal to the base station for a predetermined period of time, and when the mobile station presses the off-hook switch during a second call, it sends an on-hook signal to the base station only while it is pressed. When the base station receives an off-hook signal for a 9 call, it “connects” the line relay.
When the off-hook signal is received in the talking state (off-hook state), the line relay can be "disconnected" only while the off-hook signal is being received.

In addition, when the mobile station presses the off-hook switch during a 2nd call, it sends out an on-hook signal for a predetermined period of time, and when the off-hook switch is pressed during a call, the mobile station sends an on-hook signal for only as long as it is pressed, and when the on-hook switch is pressed, it sends an on-hook signal for a predetermined period of time. When the base station receives an off-hook signal, the base station connects the line relay to put it into a call state, and when it receives an on-hook signal in the call state, it turns on the line relay only while receiving the call. When the on-hook signal and end-of-call signal are received, the line relay is disconnected.
It can be disconnected.

Therefore, the hooking operation transmits the off-hook signal r ζ
) It's extremely simple, just press the button.

〔Example〕

The present invention will be described in detail below with reference to two drawings.

The drawing is a block diagram showing the configuration of an embodiment of the wireless telephone device according to the present invention, and FIG. 2 shows only the parts related to the present invention. In the figure, 1 is a mobile station, and a transmitting unit 11.
Signal generator 12. Control unit 13, off-hook switch 14
and an on-hook switch 15. 2 is a base station, which includes a receiving section 21, a signal detecting section 22. Control unit 23. It has a hybrid circuit 24 and a line relay 25.

3 is a telephone line, 4 is a transmitting antenna, and 5 is a receiving antenna.

There are a first embodiment and a second embodiment as described below, depending on the difference in control operations of the control section 13 of the mobile station 10 and the control section 23 of the base station 2.

(First Example) The control unit 13 of the mobile station 1 is in the 9 call state (off-hook state)
It has a state storage unit (not shown) that stores whether or not it is. When the off-hook switch 14 is pressed while this state storage section indicates the non-call state, the control section 13 instructs the signal generation section 12 to generate an on-hook signal for a certain period of time, and Set the storage unit to ``talk status''. Further, if the on-hook switch 14 is pressed while this state storage section indicates the "talking state", the control section 13 generates an off-hook signal to the signal generation section 12 while the off-hook switch 14 is pressed. instruct them to do so. Furthermore, the state memory section of the
If the on-hook switch 15 is pressed while the message " is displayed, the control section 13 instructs the signal generation section 12 to generate an on-hook signal for a certain period of time, then generate a call-end signal, and stores the state. set to "non-call state".

On the other hand, the base station 20 control section 23 also has a state storage section (not shown) that stores whether or not the base station 20 is in a two-call state. When the signal detection unit 22 detects an off-hook signal while the status storage unit indicates the “non-call state,” the control unit 23
sets the line relay 25 to the "talking state" and sets the state storage section to "talking state".Also, when the state storage section indicates "talking state", the off-hook signal is detected by the signal detection section 22. Then, the control unit 23 disconnects the line relay 25 for one time while the off-hook signal is detected. Furthermore, if the signal detection unit 22 detects an on-hook signal and a call-end signal while the status storage unit indicates the “talking status,” the control unit 23 disconnects the line relay 25.
The state storage unit is set to ``non-call state''.

Next, the operation of the first embodiment will be explained with reference to the drawings.

As an initial state, it is assumed that the state storage units of the control section 13 of the mobile station 1 and the control section 23 of the base station 2 are set to "non-calling state", and the nine wireless telephone devices are in the non-calling state.

In this state, when the mobile station 1 makes a call, when the off-hook switch 14 is pressed, the controller 13 detects the
The control unit 13 activates the signal generation unit 12 to generate an on-hook signal for a certain period of time, and sets the state storage unit to the “talking state”. The modulated wave is transmitted from the transmitting antenna 4 at the base station 2.

The modulated wave received by the receiving antenna 5 is demodulated by the receiving section 21 and input to the signal detecting section 22 . Signal detection section 22
when an off-hook signal is detected.

Based on the detected off-knock signal, the control unit 23 closes the line relay 25, connects the hybrid circuit 24 to the telephone line 3, and sets the telephone line 3 to a telephone call state, and also sets the state storage unit to the "call state."

If you want to perform a hooking operation on the mobile station 1 during this call, press the off-hook switch 14.

The control unit 13 detects this and switches the off-hook switch 1.
The signal generator 12 is controlled to generate an off-hook signal while 4 is pressed. The transmitting section 11 modulates a carrier wave using the off-hook signal generated by the signal generating section 12, and this modulated wave is sent out from the transmitting antenna 4. At this time, in the base station 2, the modulated wave received by the receiving antenna 5 is demodulated by the receiving section 21 and input to the signal detecting section 22. When the on-hook signal is detected by the signal detection unit 22, the control unit 23 disconnects the line relay 25 only while the off-hook signal is detected, and disconnects the line relay 25 when the off-hook signal is no longer detected. Then, the call status is resumed.

To end a call, when the off-hook switch 5 is pressed on the mobile station 1, the control unit 13 detects this and activates the signal generator 12 to generate an on-hook signal for a certain period of time and then generate a call-end signal. With.

The status storage section is set to the "non-call state." The transmitting section 11 modulates a carrier wave using the on-hook signal and the end-of-call signal generated from the signal generating section 12, and this modulated wave is sent out from the transmitting antenna 4. At the base station 2, the receiving antenna 5
The modulated wave received is demodulated by the receiving section 21 and input to the signal detecting section 22 . When the on-hook signal and the end-of-call signal are detected by the signal detection unit 22, the control unit 23 disconnects the telephone line 3 by turning off the line relay 25.

The standby state is set and the call is terminated, and the state storage unit is set to the "non-call state".

(Second Embodiment) In this example as well, the control unit 13 of the mobile station 1 has a state storage unit that stores whether or not it is in a two-call state. The difference from the first embodiment is that when the off-hook switch 14 is pressed while the status storage section indicates "talking state", the control section 13 causes the signal generation section 12 to press the off-hook switch 14. to generate an on-hook signal while

Further, the base station 20 control unit 23 also has two control units as in the first embodiment.
It has a status storage unit that stores whether or not the phone is in a call status. The difference from the first embodiment is that when the state storage section indicates the "talking state", the signal detection section 22 detects an on-hook signal.

The control unit 23 turns off the line relay 25 while the on-hook signal is detected.

Next, the operation of the second embodiment will be explained with reference to the drawings. However, in this embodiment, the operation for making and ending two calls is the same as the operation for the first embodiment, so the hooking operation during two calls is performed.

I will only explain.

When performing a hooking operation on mobile station 1 during a call,
When the off-hook switch 14 is pressed, the control section 13 detects this and controls the signal generation section 12 to generate an on-hook signal while the off-hook switch 14 is pressed. The transmitting section 11 modulates a carrier wave using the on-hook signal generated by the signal generating section 12, and this modulated wave is sent out from the transmitting antenna 4. At this time, in the base station 2, the modulated wave received by the receiving antenna 5 is demodulated by the receiving section 21,
The signal is input to the signal detection section 22. When the on-hook signal is detected by the signal detection unit 22, the control unit 23 “cuts off” the line relay 25 only while the on-hook signal is detected.
Then, when the on-hook signal is no longer detected, the line relay 25 is disconnected and the communication state is resumed.

〔Effect of the invention〕

As explained above, according to the present invention, the hooking operation in a wireless telephone device can be performed easily and at any timing.
