Abstract

PURPOSE:To shorten time until incoming ringing by controlling a call incoming response signal from a radio telephone set in a main equipment, in the radio telephone system equipped with a connector to exeute radio connection and the main equipment to control connection with a telephone line and to control the connector. CONSTITUTION:A main equipment (ME) 1, connectors (CE) 21-24 and radio telephone sets (RTEL) 31-34 are similarly constituted excepting for an incoming call connection control operation. Incoming call response signals T1-T4 are inputted through the CE 21 or an antenna 205 to a control part 203 and analyzed in this part. When receiving the final incoming call response signal from the RTEL provided in a system, for example, from either the CE 21 or 23, the ME 1 transmits a disconnection signal to the CE not transmitting the incoming call response signal. This response completion signal or disconnection signal is inputted through a hybrid 201 to the control part 203 and analyzed inthis part. Thus, the control part 203 stops the transmission of incoming call signals.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wireless telephone device (cordless telephone), and more particularly to a call receiving method for a cordless telephone used in a button telephone device.

(Prior Art) Masu 7 A button telephone device (key telephone system) in which a cordless telephone is used will be explained with reference to FIG.

In FIG. 2, 1 is a main device (ME) that controls the entire system, and 21 to 24 are connection devices (CE) that are controlled to be connected to the MEI and wirelessly connected to cordless telephones (RTE-L) 31 to 34. . Here, CF3I and 22
covers wireless zone Z1; L, CE2B and CE24 cover wireless zone Z2. The R stations 31 to 34 are movable within and between wireless zones. In addition, Ll is M
Wired telephone line connected to El, L2 is MEI and CE2
This is a connection line that connects 1 to 24.

First, as an initial operation, MHI uses CF3 in wireless zone Z1.
I and CE23 in wireless zone Z2 are designated as a receiving state where calls can be made and received, and CE22 and CE24 are designated as a standby state.

Next, an example of an incoming call connection method of a conventional wireless telephone device will be described.

As shown in FIG. 2, it is assumed that the R stations 31 and 32 are in the wireless zone Z1, and the R stations 33 and 34 are in the wireless zone Z2.

Here, with reference to Figures 3 and 4, MEI is the power supply 1
41 and wired telephone line Ll (external line 171°172, and 1
73) external line interfaces 101, 10 connected to
2. and 103 and connection line L2 (CE lines 161, 162,
163. and 164) connected to the CE interfaces 161, 162.163. and 164.

here.

When the MHI receives an incoming call signal via the outside line 171.

This incoming call signal is detected by the outside line interface 101 and input to the control section 131. in this case.

Since CF3I and CF23 are in the receiving state, the control unit 13
1 via the CE interfaces 121 and 123
An incoming call signal R1 including incoming call information indicating that the call is incoming from the outside line 171 is transmitted to the F3I and CE23.

Furthermore, with reference to FIG. 5, each CE is
01, a power supply 204, and a control unit 203. Transceiver 202
．． The transmitter/receiver 2
02 is connected to an antenna 205.

The incoming call signal R1 sent from the MHI is input to the control unit 203 via the hybrid 201 in the CFs 3I and 33, where it is analyzed. Based on this analysis, the control unit 203 sends an R-place call signal to each R-place from the transceiver 202 via the antenna 205. This R station incoming call signal includes a system specific telephone number and an R station specific extension number.

By the way, each CE21 and CE23 does not know whether the R location is in their own wireless zone or in the wireless zone they cover.
As shown in the figure, the CFs 3I and 23 respond to the incoming call signal from the MEI with the incoming call signals Sl, S2 . S3. and S4 are sent out sequentially. In addition, here, the 1st call number Sl, S2 . S
3. and S4 are R positions 31, 32, 33., respectively. and 3
Corresponds to 4.

Referring also to FIG. 6, each R position is connected to the antenna 30 as shown.
7, and this antenna 307 is equipped with a transmitter/receiver 301
It is connected to the. and.

The transmitter/receiver 301 includes a microphone 303 and a speaker 304.
is provided. Further, a reception level determiner 309 is connected to the transceiver 301.

A control unit 302 is connected to the transceiver 301 and the reception level determiner 309, and a keyboard 3 is connected to the control unit 302.
061 display section 306. and a buzzer 310. Note that each R station operates intermittently at predetermined intervals to save the battery 308.

The above-mentioned incoming call signal is received by the transceiver 301 via the antenna 307 at each R position, inputted to the control unit 302, and analyzed there.

The control unit 302 checks the system-specific identification number included in the incoming call signal and the R-location-specific extension number.

When the extension number matches the own extension number, the control unit 302 controls the transmitter/receiver 301 to transmit from the antenna 307 to CH21 or CH2.
3, an incoming call response signal containing a system-specific identification number and an R-specific extension number is transmitted. Here, each R position 31 to 34
The incoming call response signals sent by the incoming call response signals T1 to T1 are respectively
Let it be T4. These incoming call response signals are received by the transmitter/receiver 202 via the antenna 205 of CH21 or CH23, input to the control unit 203, and analyzed. Then, the control section 2
In step 03, the system-specific identification number included in the incoming call response signal is verified, and if they match, the extension number specific to each R location is temporarily stored. When CHs 21 and 23 receive the incoming call response signals from all the R stations, they stop transmitting the two incoming call signals.

However, in the above example, since the R stations 31 and 32 are moving in the wireless zone Zl and the devices 33 and 34 are moving in the wireless zone Z2, the R stations 31 and 32 . CH23
In this case, only incoming call response signals from the R stations 33 and 34 are received. Therefore, CH21 and CH23 are even after all of R~4 have transmitted the incoming call response signal.

Sends an incoming call signal. In other words, CH21 and CH23 send out an incoming call signal for a predetermined period of time.

CHs 21 and 23 transmit CH designation signals to the R location after a predetermined period of time has elapsed. The extension number of the R station that responded first (R stations 31 and 33 in this case) is inserted into this CH designation signal.

In other words, CH21 uses the CH designation signal u1, and CH23 uses the CH designation signal u1.
Sends a designation signal u3. When the R stations 31 and 33 receive the CH designation signals u1 and u3, respectively, they switch the channel to the channel (CH) designated by the CH designation signals u1 and u3. Furthermore, the R location that matches the extension number of the CH designation signal transmits a CH switching completion signal to CH21 or CH23. When CH 21 or 23 receives the CH switching completion signal, it transmits a bell ringing signal to each R location.

That is, CH21 sequentially sends out bell ringing signals v1 and v2 (corresponding to R positions 31 and 32, respectively), and CH23 sequentially sends out bell ringing signals v3 and ■4 (corresponding to R positions 33 and 34, respectively).
(corresponding to) are sent out sequentially.

When the R station receives the bell ringing signal, the buzzer 310 rings the bell to notify the user of the incoming call.

Here, when the user presses the call button on the keyboard 306 of the R station 31, the control unit 302 waits until it receives a bell ringing signal that matches the extension number, and sends the incoming call response signal W1 including the extension number to CH21. Send to. When the CEI receives the incoming call response signal W1, it transmits an incoming call response signal including this extension number to the MHI. When the MHI receives the incoming call response signal, it transmits the AF ON signal x1 including the extension number to the C
After the transmission is completed, the switch 111 is controlled to connect the outside line interface 101 and the CE interface 121 shown in FIG.

On the other hand, ME1 transmits a disconnection signal to other CH23. Note that a hold sound source 151 is connected to the switch 111 and is controlled by the control unit 131.

When CH23 receives the disconnection signal, it transmits the disconnection signal to R position 33.
and 34, and then returns to the standby state.

On the other hand, CH21 that received the AFON signal
and 32, and send the AF ON signal x1 to 32, turning the audio circuit on
Set it to N. Since the extension number of the AF ON signal x1 and the own extension number of the R station 31 match, the audio circuit is turned on.

As a result, the R station 31 can make a call using the outside line 171. Since the extension number of the AF ON signal X1 and the own extension number of the R station 32 do not match, the bell stops ringing and returns to the holding state.

[The problem that the invention aims to solve] By the way, in the conventional wireless telephone device mentioned above.

The connecting device cannot know how many wireless telephones are in its own zone, and therefore continues to transmit the incoming call signal even after the incoming call response signals from all the wireless telephones have been transmitted. Therefore,
It takes a while for the bell to ring.

There is a problem in that the control channel is used in vain.

An object of the present invention is to provide a radio telephone device that can effectively use control channels.

(Means for Solving the Problems) In the present invention, a plurality of wireless zones for wireless service are set, a wireless telephone that moves within the zone, and a wireless telephone that is arranged in each zone and is located within the zone. A wireless telephone device having a connection device for making a wireless connection with a telephone, and a main device for controlling connection to a telephone line and controlling the connection device.

The connecting device includes first sending means for sending a second calling signal to the wireless telephone for a predetermined period of time in response to the first calling signal from the main device.

a second sending means for sending a second call response signal to the main device in response to a first call response signal from the wireless telephone; third sending means for stopping the sending of the second incoming call signal and sending out a channel designation signal to the radio telephone; the main device detects an incoming call from the telephone line; a fourth transmitting means for transmitting the first incoming call signal to the wireless telephone; and determining whether or not there is a response from all of the wireless telephones except those in use when receiving the second call response signal. A wireless telephone device characterized in that it is provided with a determining means and a fifth sending means for transmitting the response completion signal when the determining means determines that there has been a response from all of the wireless telephones. It will be done.

[Example code] The present invention will be explained below with reference to nine examples.

In this embodiment, the button telephone system is configured as shown in FIG.
)21-24. The radio telephones (R units) 31 to 34 are also constructed in the same manner except for the incoming call connection control operation.

As shown in Figure 2, R locations 31 and 32 are wireless zone Z.
1, it is assumed that the R stations 33 and 34 are moving in the wireless zone Z2.

Referring to FIGS. 1, 2, 3, 5, and 6, an incoming signal from the outside line 171 is detected by the outside line interface 101 of the M El and is input to the control unit 131. Since the CF3I and the CE23 are currently in the receiving state, the control unit 131 controls the CE interface 121 and the C
CF3I and CE23 via E interface 123
, an incoming call signal including incoming call information indicating that the call is to the outside line 171 is transmitted.

This incoming call signal is CF3I and 23 hybrid 201
The data is input to the control unit 203 via the , and analyzed there. Based on this analysis, the control unit 203 transmits signals from the transmitter/receiver 202 to the R positions 3-1 to 34 via the antenna 2.5.
An incoming call signal (an incoming call signal on R) including an identification number unique to the system and an extension number unique to R is transmitted. In other words, CF3
I and CE 2 B C Incoming call signal Sl, S2. S3° and S4 are sent out sequentially.

These incoming call signals are sent to the antennas 307. The signal is input to the control unit 302 via the transceiver 301 and analyzed. The control unit 302 compares the system-specific identification number included in the incoming call signal with the extension number specific to the R location, and if the number matches the own number, the control unit 302 transmits the call from the transceiver 301 to the CF 3I or 23 via the antenna 307. Incoming call response signal T containing a system-specific identification number and an R-specific extension number
1 to T4 are transmitted.

These incoming call response signals T1 to t4 are sent to the control unit 203 via the antenna 205 of the CF3I or 23 and the transceiver 202.
is input to and analyzed here. The control unit 203 verifies the system-specific identification number included in the incoming call response signal, and if they match, transmits an incoming call response signal including an extension number specific to the R location to the MHI via the hybrid 201.

It is input to the control unit 131 via the CE interface 121 or 123 of the MEI and analyzed.

The control unit 131 temporarily stores the extension number unique to the R location included in the incoming call response signal.

MHI is the last call response signal of the R unit included in the system, and when receiving call response signals from both CF3I and CE23, it responds to CEI and CE3 via CE interfaces 121 and 123. Send a completion signal. On the other hand, when only one of the CF3I and CE2B receives the incoming call response signal, it does not transmit the first incoming call response signal and sends a disconnection signal to the CE.

This response completion signal or disconnection signal is input to the control unit 203 via the hybrid 201 of CH21 and CH23 and analyzed there. As a result, the control unit 203 stops transmitting the incoming call signal.

CH21 or CH23 are all RTs included in the system.
CHs 21 and 23 return to standby when receiving a disconnection signal when receiving an incoming call response signal from or transmitting an incoming call signal for a predetermined period of time.

In other cases, a CH designation signal is sent to RT. The extension number of the RT that responded first is inserted into this CH designation signal.

Upon receiving the CH designation signal, each RT switches to the designated CH. Further, the RT that matches the extension number of the CH designation signal transmits a CH switching completion signal to the connecting device. CH2
When 1 or 23 receives the CH switching completion signal, it sequentially sends a bell ringing signal including the extension number to RTvl~v4.

When each RT receives the bell ringing signal, it rings the bell with the buzzer 310 to notify the user of the incoming call. User is RT3
When the call button on the keyboard 306 of No. 1 is pressed, the control unit 302 waits until a bell ringing signal with a matching extension number is received, and sends the incoming call response signal W1 including the extension number to C.
Send to El. When CH21 receives the incoming call response signal W1, it transmits one incoming call response signal W1 to the MHI.

When the MEI receives the incoming call response signal W1, it transmits an AF ON signal x1 including the extension number to CH21.

After the transmission is completed, the switch 111 is controlled to connect the outside line interface 101 and the CE interface 121. Furthermore, a disconnection signal is transmitted to CH23.

When CH23 receives the disconnection signal, it transmits the disconnection signal to RT33.
and 34, and returns to the standby state. On the other hand, AF
CH21, which has received the ON signal x1, transmits the AF ON signal x1 to RTs 31 and 32 to turn on the audio circuit. Since the extension number of the AF ON signal x1 and the own extension number match, RT21 turns on the audio circuit. This allows the RT 21 to make a call using the outside line 171.

Since the extension number of the AF ON signal and the own extension number do not match, the RT 22 stops ringing the bell and returns to the holding state.

[Effects of the Invention] As explained above, according to the present invention, whether in a wireless zone or multiple zones, the main device manages the incoming call response signal from the wireless telephone, thereby reducing the time until the incoming call rings. There is an effect that it can be done.
