Next, the calling procedure of the wireless telephone device of this embodiment will be explained.

First, a call request will be explained using FIG. 5. First, the plug of the transmitter 302 or the receiver is inserted into the jack of the main body of the mobile device (step S501, see FIGS. 3(b) and 3(c)). As a result, the connection detection unit 314
outputs an insertion detection signal, and a communication channel connection request is made. The insertion detection signal is input to the CPU 305,
CPU 305 starts a timer (step 5
502). If the dial key is not pressed after a certain period of time (step 5503.5s04), it is determined that no call channel connection request has been made and the initial state is set (step 3505). If the dial key is pressed within a certain period of time, it is determined whether or not the call channel is connected (step 3506); if not, the call channel is connected (step 35).
07).

Next, the communication channel connection procedure will be explained using FIG. 6. FIG. 6 shows the contents of the speech channel connection (sso?> in FIG. 5).

First, a communication channel connection procedure in a mobile device will be explained. The control unit (CPU) 30 handles the call channel connection request.
5 (3601), the mobile device searches for an empty channel in the receiving frequency band (5602).

After confirming that the control channel is free (3
503), and transmits a calling signal along with the data of the free channel on the control channel (3604).

At this time, if the control channel is being used, a connection failure notification is issued (5612). Note that the calling signal includes an ID. The mobile device monitors whether a call response signal is received from the fixed device (3605). If a call response signal is not received after a certain period of time, either search for an empty channel again or notify the user that connection is not possible (S611).
. When the mobile device receives a call response signal from the fixed device, it confirms whether the TD sent as the call signal and the ID received as the call response signal are the same (360G).

If it is determined that the IDs are not the same, search for an empty channel again or notify the user that connection is not possible (
5611). After confirming the ID in this way, the process moves from the control channel to the call channel (S607).

The mobile device sends a channel switching completion signal to the fixed device using the communication channel (360g>. The mobile device monitors the response signal from the fixed device (3609). If there is no response signal, it will retry once as a carrier disconnection. or sends a connection failure notification (5613).When receiving the response signal from the fixed device, the mobile device turns on the audio receiving circuit (3610)
. This means that the communication channel between the fixed device and the mobile device is connected, and a conversation can be made (3650).

Next, the procedure for connecting communication channels in the fixed device will be explained using FIG. 6. The fixed device monitors the control channel to see if a call request is received from the mobile device (S621). When a call request is received, it is determined whether the ID sent in the call signal is correct (3622).

If correct, a call response signal is sent to the mobile device using the control channel (S623). If the ID is different or if the channel is not vacant, the control channel monitoring state is returned to (S622). After sending the call response signal, the mobile device moves from the control channel to the communication channel (5624) and monitors whether a channel switching completion signal is received from the mobile device (36).
25). If it comes, send a response signal 5626)
, If you do not come, your career will be terminated (3627),
Return to control channel monitoring state. When the response signal is sent, the communication channel between the fixed device and the mobile device is connected, and a conversation can be made (5620).
.

In this way, the communication channel connection request is accepted and the process of connecting the communication channel is performed. At this point, there is a possibility that the open dial key that is performing the process of connecting the call channel is pressed down. When the dial key is pressed (step 5503 in FIG. 5), if the call channel is not connected (step 5505), a calling signal is sent as in step 5604 in FIG. 6 (step 5507). If the dial key is pressed before the call channel is connected (step 5sQ3.
5506), memorize the dial data (step 3)
50g). When the call channel is connected, the stored dial data is sent (steps 3506 and 3509).
. Further, dial data corresponding to the dial keys pressed after the communication channel is connected is sequentially sent out (step S5θ9).

Next, the incoming call processing will be explained using FIGS. 7 to 10.

First, communication channel connection in a fixed device will be explained with reference to FIG. When a call is received via a line such as a general subscriber line or PBX (3701), the main device 102 (FIG. 1) selects a mobile station to receive the call (3702).

In order to receive the call to the mobile device, the fixed device receives the call. When the fixed device receives an incoming call, the fixed device searches for an empty channel in the receiving frequency band (5703). If there is a free channel, after confirming that the control channel is free (370
4) Sends an incoming call signal on the control channel together with the data of the free channel and data specifying the mobile device to ring (3705). An ID is assigned to the incoming call signal. Here, the fixed device sets a timer and monitors the incoming call response signal from the mobile device (5706-370g). When an incoming call response signal is returned from the mobile device, the fixed device resets the timer and moves both transmission and reception from the control channel to the communication channel (3710). Then, a timer different from the above-mentioned timer is set and the arrival of a channel switching completion signal from the mobile device is monitored (5711 to 3713).

When the fixed device receives a channel switching completion signal from the mobile device, the fixed device sends to the mobile device a ringing control signal according to the incoming call mode and the mobile device to be ringed (3901).

Next, a case in which the fixed station cannot receive a response signal from the mobile station will be explained using FIG. 7.

First, a case will be described in which a channel switching completion signal from a mobile device cannot be received. In this case, the communication channel being captured is set to carrier disconnection (S715).

Then, it is determined whether there is any free channel other than the channel previously designated for this incoming call (57] 6).

If there is an empty channel, it is determined whether there is any other mobile device that can receive the call (3717). There is an empty channel,
If there is a mobile device that can receive a call, a request for receiving a call is made to that mobile device again.

If there is no free channel or if there is no mobile device that can receive the call, perform the fixed device incoming call ringing process described later (first step).
Figure 0).

Next, a case in which the incoming call response signal from the mobile device cannot be received will be explained using FIG. 7. In this case, it is determined whether there is another mobile device that can receive the call (S717>).

If so, an incoming call request signal is sent to that mobile device. If not, perform the fixed-line call ringing process described later (Figure 10).

Next, communication channel setting in the mobile device will be explained using FIG. 8. The mobile device monitors the incoming call signal from the fixed device (SIIO+>. When receiving the incoming call signal, the mobile device checks whether the ID data in the received signal matches (31102). If they do not match returns to the standby state again. If there is a match, an incoming call response signal is sent (S8 (13). Then, the reception and transmission frequencies are switched from the control channel to the communication channel (5804), and if the communication channel is free (51105)
). If the channel is vacant, a channel switching completion signal is sent (Sl106).

If it is not available, the carrier is disconnected and then returns to the standby state (5807). After transmitting a channel switching completion signal, the arrival of a ringing control signal from the fixed device is monitored (5808).

Next, the ringing control will be explained using FIG. 9. After connecting the communication channel by connecting the communication channel on the fixed device (Fig. 7) and setting the communication channel on the mobile device (Fig. 8), ringing control is performed using the communication channel (39).
01,902), the fixed device sends a ring tone according to the incoming call mode to the mobile device through the communication channel, and determines whether the ringing from the line interface unit 202 (FIG. 2) stops (S903). until the carrier from the mobile device expires (S904) or there is a connection request from the mobile device (S904).
3905), make the mobile device ring (5906.591
O, Fig. 8 5809).

In the mobile device, when there is a ringing, the switch sensor of the connection detection unit 314 (Figure 3) determines whether the plug is inserted (31110 in Figure 8), and if the plug is inserted, the connection button switch is activated. 5] When 4 (Figure 5) is pressed (5g+1), the ringing will stop.5Il12)
, sends a connection request to the fixed device (Sll13). If the plug is not inserted, the ringing continues until the plug is inserted or the incoming call stops (51110.
5814). If the incoming call stops without the plug being inserted, the carrier is disconnected (3815). When the plug is inserted, when the connection button switch 514 is pressed (
3810, 5till), stop ringing 5812),
Automatically issues a connection request to the fixed device (5g+3).

Note that, in addition to making the mobile device ring, the presence of an incoming call request may be displayed on a display or the like.

If the incoming call stops (5903), the fixed device issues a command to the mobile device to stop ringing 5910), sends a request to clear the incoming call display 3911), and disconnects the carrier of the transmission channel on the mobile device side. (S9+2), and then stops its own carrier transmission and ends (S913)6
When there is a connection request from the mobile device, the fixed device should not issue an incoming ringing stop command to the mobile device (3906) and send an incoming call display clear request (590?). ), Send a call display designation signal 3908), Stop the ringing on the mobile device side and turn on the audio circuit, and turn on the audio circuit on the fixed device (3908).
3909).

Next, the incoming call ringing process in the fixed device will be explained using FIG. 10. At step 5703 in FIG. 7, if there is no free channel, the process proceeds to step 51001 in FIG. 10, and the fixed device itself rings an incoming call. When the incoming call stops (310
02) Stop ringing the incoming call (31013).

If a connection request signal is received from the mobile device here (SI
003) Performs wireless line connection processing between the fixed device and the mobile device. That is, the ID included in the connection request signal is checked (31004), and if OK, a connection request acceptance signal is transmitted to the mobile device (31005), and the control channel is switched (SI006). Then, it sets a timer (31007) and monitors the arrival of a channel switching completion signal from the mobile device (51008. SI009).

Then, if the channel switching completion signal does not arrive, the communication channel is released (31014). When the channel switching completion signal is received, stop the ringtone of the fixed device (31010
), 5IOI+) to send a communication display signal to the mobile device.
, performs communication path connection processing with the incoming call (51012)
.

Next, call termination control in the mobile device will be explained using FIG. 11. To end a call on the mobile device, press the disconnect button 515 (Figure 5) (unplug the earphone jack,
If either the antenna storage or the earphone storage is achieved, the same effect as pressing the disconnect button will occur) or when a termination instruction is received from the fixed device (31201.312
02). In addition, calls may be cut off when the carrier is cut off for a certain period of time (31204.31206-3
1208.31216-51220).

When the disconnect button 515 is pressed or when a call termination instruction is received from the fixed device, the mobile device stops reception (3121
1) Output a call termination tone 51212) The mobile device sends an on-hook signal to the fixed device to instruct the fixed device to disconnect the transmission carrier (S12] 3). Thereafter, the carrier of the mobile device is disconnected (SI214).

When any other valid key is pressed, the process shifts to other processing (SI203.5I215).

Next, a description will be given of processing when a carrier is disconnected in a mobile device. When a carrier disconnection signal is received from the control unit 305 serving as a carrier monitoring unit, the mobile device starts outputting a warning sound (51204, 51206). Then, a timer is set (S1207). If the timer expires without a carrier, reception will stop (SI208.3121
6.31217). After stopping the warning sound, it transmits an on-hook signal and stops transmitting (31218-51
220). When it is determined that there is a carrier before the timer expires, the output of the warning sound is stopped, and after the timer is cleared, normal reception operation is resumed (S1208 to 51
210).

Next, call termination control in the fixed device will be explained using FIG. 12. A fixed device terminates a call when it receives on-hook information from a mobile device or when a termination instruction is received from the main device (51301.51302).
. Another example of a call disconnection is when the carrier is disconnected (51307 to 5I310).

When receiving on-hook information from the mobile device, it stops both transmission and reception, turns off the busy display, and then sends on-hook information to the main device (31301.31319-31
321). When a termination instruction is received from the main device, it starts monitoring whether on-footer information is received from the mobile device and starts a timer (SI302.51314 to 51317).
. When on-hook information is received, the same process as before is performed and then the process ends (SI315). If the timer exceeds, clear the timer, perform the same processing as when receiving on-hook information, and terminate (31317.3
1318). If there is another valid key from the mobile device, other processing is performed (SI313).

Next, the processing when the carrier is disconnected in the fixed device will be explained. When a carrier disconnection signal is received from the control unit 205 serving as a carrier monitoring unit, the fixed device starts outputting and displaying a warning (51304 and 51305). Then, a timer is set (51306). When the timer expires without a carrier, after clearing the timer, a termination signal is transmitted (S] 307 to 31310).

Thereafter, the same processing as when receiving on-hook information from a fixed device is performed (31319 to 5I32+). If it is determined that there is a carrier before the timer expires, the timer is cleared, the output of the warning display is stopped, and normal reception operation is resumed (31311.SDI2).
.

In the above-described embodiment, a lock switch H1 as shown in FIG. 13 is provided at the connection part between the earphone and microphone (315 in FIG. 3(a)) to mechanically lock the earphone and microphone so that they do not come off during a call. You may. Furthermore, if the microphone or earphone is disconnected during a call, a signal that detects this may be used as the user's intention to end the call, and the process may proceed to a disconnection procedure. In the figure, 132 is a lock lever, the solid line indicates the locked state, and the dashed line indicates the unlocked state. +33 is a plug.
