Therefore, the second mobile device which has transmitted the call request message to the fixed device does not receive a call response message indicating that the call is available from the fixed device.

At this time, the second mobile device which has transmitted the call request message generates a call failure sound through an internal speaker when a predetermined time elapses after outputting the call request message, indicating that the call for the call request has failed. . Thereafter, when the user of the second mobile device presses the dish call key after a predetermined time elapses while the call is continued between the first mobile device and the fixed device, the user of the call failure notification is notified.

When the user of the first mobile device that is in communication with the fixed device ends the call, the first mobile device transmits a call termination message to the fixed device. At this time, the fixed device receiving the call termination message transmits a termination response message to the fixed device in response to the input of the received call termination message. The first mobile device which has received the end response message from the fixed device ends the call with the fixed device.

When the user of the second mobile device presses a call key while the call between the first mobile device and the fixed device is terminated, the call between the first mobile device and the fixed device is made in the same manner.

However, in the conventional call control method as described above, if a user of any other portable device wants to make a call when a mobile device is in communication with a fixed device, whether or not a communication path with the fixed device is formed by pressing a call key from time to time.

Hereinafter, the operation of the embodiments according to the present invention will be described in detail with reference to FIGS. 1, 2, and 4 to 13.

[First embodiment: When a mobile device makes a call reservation to a fixed device]

First, before describing various embodiments according to the present invention, a wireless telephone capable of using a plurality of portable devices, for example, first, second, and third portable devices each having a configuration as shown in FIG. In the following description, it is assumed that the first mobile device and the fixed device are in a call state.

Now, as shown in FIG. 4, when the user of the second mobile device presses the call key while the first mobile device and the fixed device are in the call state through the A channel, the second mobile device is in a standby state by the input of the call key. Sends a call request message to the B channel where the idle channel is found. At this time, the fixed device is already in a call state with the first mobile device and thus cannot receive the call request message transmitted from the second mobile device.

Therefore, the second mobile device which has transmitted the call request message to the fixed device does not receive the call response message indicating that the call is available from the fixed device as described above. At this time, if the call response message is not input for a predetermined time after the second mobile device which has sent the call request message outputs the call request message, a warning sound as shown in FIG. It outputs a call failure tone, indicating that the call for the call request failed. Thereafter, when the user of the second mobile device inputs the reservation function key, the second mobile device internally displays the reservation call state and the reservation time in response to the input of the reservation function key as shown in FIGS. 12 (a) and (b). A reservation bit set in the memory and a reservation timer are set, and it is searched whether a call termination response message is received within the reservation time set in the reservation timer.

On the other hand, when the user of the first mobile device that is in the call with the fixed device in the state in which the second mobile device retrieves a call termination response message as described above, and terminates the call by pressing the call key, the first mobile device A call termination message is sent to the fixed device. The fixed device receiving the call termination message output from the first mobile device sends a call termination response message to the first mobile device and the second mobile device in response to the input of the received call completion message. Send for seconds. The first mobile device which inputs the end response message from the fixed device and the fixed device which outputs the call termination response message end the call and enter the standby state. Receiving a call termination response message output from the fixed device, the second mobile device outputs a call possibility as shown in FIG. 13 (B) through the speaker.

When the user who hears the possibility of talking through the speaker presses a call key, the second mobile device transmits a call request message to the fixed device as described above. At this time, the fixing device is in the standby state and receives the call request message transmitted from the second mobile device, and the receiving device receives the call response message for the call request to the second mobile device.

When the second mobile device receives the call response message sent from the fixed device, the call state between the fixed device and the second mobile device is successfully established.

An example of the specific operation of the second mobile device as described above will be described in more detail with reference to the flowchart of FIG. 5.

In the standby state, the microcomputer 12 of the second mobile device scans the standby channel in step 100 of FIG. 5 and reads a key input port in step 5102 to search whether a call key is input. If it is determined that the call key is input in the above state, the microcomputer 12 of the second mobile device searches for a idle (empty) channel among the plurality of call channels in step 104. In addition, the microcomputer 12 controls the transmission / reception control unit 28 and the transmission unit 20 in step 108 to transmit the call request message data through the channel, and in step 110 to FIG. Drives a transmission timer TXTIMER located in the form of: The call request data transmitted from the second mobile device by step 108 is propagated to the fixed device through the transmitter 20.

The transmission timer TXTIMER driven in step 110 is a timer for limiting a transmission time of call request data. In step 112, the microcomputer 12 performs the search for whether call response data is received.

If the fixed device is not in a state of communicating with any portable device in a state of operating as described above, i.e., executing steps 112 and 114, the microcomputer 32 in the fixed device transmits from the second mobile device. The received call request data is received through the receiver 38, and the call response data in response to the reception of the call request data is transmitted to the second mobile device through the transmitter 36. At this time, the microcomputer 12 in the second mobile device receives the call response data transmitted from the fixed device through the receiver 24.

The second mobile device determines that the response data has been received in step 112, and in step 118 resets the reservation bit set in the internal memory area as shown in FIG. Release it. The microcomputer 12 performing the process 118 performs a call service with the fixed device in step 120, and searches whether the call is terminated in step 122. The call termination is performed by searching the input state of the call key. If the call is not finished in step 122, the microcomputer 12 in the second mobile device repeats the process from step 120. If the call is terminated, the call termination data is transmitted through the transmitter 20. In operation 124, the microcomputer 12 of the second mobile device that transmits the call termination data indicating the call termination state analyzes the data output from the receiver 24 and searches whether the termination response data has been received. If the end response data is not received in step 126, the microcomputer 12 in the second mobile device repeats step 126 and waits until the end response data is received.

If the response data for the call request is not received in step 112, the microcomputer 12 searches whether the transmission timer TXTIMER is 3 seconds in step 114. That is, it is searched whether the transmission timer TXTIMER has timed out a preset time. If the value of the transmission timer is not 3 seconds in step 114, the microcomputer 12 repeats the process 112 and if the counting is completed, the call failure sound from the receiver 24 to the speaker 26. In step 116, the transmission and reception control unit 28 is controlled to return the process to step 100.

Therefore, if the second mobile device outputs call request data while the fixed device is talking to any mobile device, the second mobile device does not receive the call response data, and listens for the call failure. Done.

As described above, the microcomputer 12 in the second mobile device that performs the standby channel scan operation of step 100 searches whether 102 a call key is input. If it is determined in step 102 that the call key is not input, the microcomputer 12 reads the output of the key input unit 10 to detect whether a reservation function key is input in step 128, and the reservation function key is not input. If so, the microcomputer 12 searches whether the reserved bit set in FIG. 12 is set in the internal memory in step 134. If it is determined in step 138 that the reserved bit is not set, the microcomputer 12 returns to step 100 to repeat the above operation.

When the user of the second mobile device, which has attempted to make a call in such a state, presses the reservation function key installed in the key input unit 10, the key data corresponding to the reservation key is output from the key input unit 10, and thus the reservation function The data of the key is input to the microcomputer 12.

Accordingly, the microcomputer 12 determines that the reservation function key is input in step 128 and sets the reservation bit set as shown in FIG. 12 in the internal memory area in step 130. That is, call reservation is set. In addition, the microcomputer 12 of the second mobile device that has reserved the reservation in step 130 initializes and operates the reservation timer RESPTMRL set as shown in FIG. Run channel search. At this time, the reservation timer (RESVTMRL) is set to increase every 20msec in the timer routine.

Upon returning to the standby state by the above operation, the microcomputer 12 of the second mobile device performs steps 102 to 128 and 134 to search whether the reserved bit is set. In this case, since the reserved bit set as shown in FIG. 12A is set in the internal memory, the microcomputer 12 determines that the reserved bit is set in step 134. Search to see if an end response signal has been received. That is, it is searched whether the end response message is sent from the fixed device indicating that the call has ended. Here, the call termination response message output from the fixed device indicates that any mobile device that was talking to the fixed device terminated the call and outputted the call termination message data. To transmit.

If the end response message data has not been received in step 136, that is, if any portable device that is already in communication with the fixed device has not terminated the call, the microcomputer 12 in the second mobile device generates a message in step 5140. It is checked whether the reservation timer time incremented by 20 msec period is 10 minutes.

If the increase time of the awake timer exceeds 10 minutes, the microcomputer 12 resets the reservation timer set in the internal memory and increases every 20 msec in step 142 to release the reservation state. If the above process is repeated and the time of the reservation timer is less than 10 minutes, the operation of the above processes is repeated in the current reservation state.

If any mobile device transmits the call termination message data to the fixed device in the reservation state, the fixed device sends the call termination message data to all mobile devices in response to the input of the call termination message data as described above. Send. At this time, the second mobile device receives the call termination message data transmitted from the fixed device through the receiving unit 24, and by receiving the end message, the microcomputer 12 of the second mobile device receives the 136th call. In step 138, it is determined that the end message data has been received, and in step 138, the speaker capable of making a call as shown in FIG.

Therefore, when the user of the second mobile device hears the call possibility output through the speaker SP, when the user who hears the call possibility presses a call key, the user of the second portable device can talk to the fixed device. That is, any mobile device that is talking to the fixed device while the second mobile device reserves a call ends the call and the call is disconnected between the second mobile device and the fixed device at the moment when the fixed device is in the standby state. A call path is outputted, and a call path between the fixed device and the second portable device, which is in a standby state at the moment a call key is input, is formed.

[Second embodiment: When the mobile device automatically transmits a call reservation and a reserved phone number to the fixed device]

First, before describing the second embodiment according to the present invention with reference to FIGS. 6 and 7, the same contents as those of the first embodiment described above will be described with reference to FIGS. 4 and 5.

As described above, when the user of the second mobile device presses the call key in a situation where the first mobile device and the fixed device are in a call state through the A channel, the speaker to the speaker SP of the second mobile device (SP) is connected to the fourth. As described above with reference to Figs. 5 and 5, a call failure tone, which is the same warning sound as in Fig. 13B, is output. That is, the second mobile device indicates that a call for a call request for outputting a warning sound as a call failure sound as shown in FIG. 13B to the internal speaker has failed.

Thereafter, when the user of the second mobile device inputs the reservation function key, the second mobile device displays the reservation call state and the reservation time in response to the input of the reservation function key as described above. The reservation bit set in the internal memory and the reservation timer (RESVTMRL) are set as shown in FIG. 12, and the inside of the reserved dial buffer set in the internal memory is initialized as shown in FIG. Then, the input dial digit is stored in the reserved dial buffer, and it is searched whether a call termination response message is received within the reservation time set in the reservation timer RESPTMRL.

When the user of the first mobile device, which has been talking to the fixed device in the above state, presses a call key to terminate the call, the first mobile device transmits a call termination message to the fixed device as described above. At this time, the fixed device for receiving the call termination message output from the first mobile device sends a call termination response message to the first mobile device and the second mobile device in response to the input of the received call termination message. Transmit for 5 seconds. The first mobile device which inputs the end response message from the fixed device and the fixed device which outputs the call end response message end the call, enter the standby state, and receive the call end response message outputted from the fixed device. 2 The portable device outputs a call capable sound as shown in FIG. 13B through the speaker.

When the user of the second mobile device that has heard the call function sound through the speaker presses a call key, the second mobile device transmits a call request message to the fixed device as described above. At this time, the fixing device is in the standby state and receives the call request message transmitted from the second mobile device, and the receiving device receives the call response message for the call request to the second mobile device.

When the second mobile device receives the call response message transmitted from the fixed device, the second mobile device sends out a dial digit stored in a reserved buffer located in the internal memory and services the call mode.

Therefore, when the second mobile device reserves a call with the mobile device while the fixed device is talking to any mobile device and stores a dial digit to be transmitted, the call between the fixed device and the mobile device is terminated. As soon as a communication path is established with the fixing device, a reserved dial digit is automatically sent out.

The detailed operation of the second portable device as described above and the second embodiment will be described in more detail with reference to the flowchart of FIG. 7.

In the standby state, the microcomputer 12 of the second mobile device scans the standby channel in step 100a of FIG. 7, which is the same process as in FIG. 5, and reads a key input port in FIG. Search for input. If it is determined that the call key is input in the above state, the microcomputer 12 of the second mobile device performs a call to the fixed device by performing the processes of FIGS. 104A to 116a of FIG. Send the request message data and check whether the response data is received within the time set by the transmission timer.

If it is determined that the response data is received within the time set in step 112a, the microcomputer 12 in the second mobile device searches for the reservation state set in the internal memory in step 7114a. At this time, since the reservation is not performed, the general call mode is serviced by performing the processes 120a to 126a of FIG. 7 which are the same processes as the processes 120 to 126 described above with reference to FIG.

However, if it is determined that the response data for the call request is not received in step 112a, the microcomputer 12 in the second mobile device searches for the transmission timer TXTIMER for 3 seconds in step 114a. That is, it is searched whether the transmission timer TXTIMER has timed out a preset time. If the value of the transmission timer is not 3 seconds in step 114a, the microcomputer 12 repeats the process 112a and if the counting is completed, the call failure sound from the receiver 24 to the speaker 12. After controlling the transmission / reception control unit 28 in step 116a to return to step 100a, the standby channel is searched for, and in step 102a and 128a, the call or reservation function key is searched for.

When the user of the second mobile device that listens to the call failure sound in the above operation state presses a reservation function key installed in the key input unit 10 to make a call reservation, the micom 12 of the second mobile device 12a displays the 128a. In the process, it is determined that a reservation function key is input. At this time, the microcomputer 12 sets a call reservation by setting a reservation bit set as shown in FIG. 12a in the internal memory area in step 130a. In addition, the microcomputer 12 of the second mobile device which has set a reservation in operation 130a initializes and operates the reservation timer RESPTMER set as 12b in the internal memory and reserves the reservation dial buffer set in FIG. 12c in step 152a. Initialize the contents of the (delete all contents), and execute the channel search in the standby state of the above-described process 100a. At this time, the reservation timer (RESVTIMRL) is increased every 20 msec in the timer routine as described above.

When the microcomputer 12 of the second mobile device returns to the standby state by the above operation, the microcomputer 12 of the second mobile device is the same process as the processes 102 to 128 and 134 of FIG. 5 described above, and processes 134a to 134a of FIG. The process is performed to find out whether the reserved bit is set. In this case, the reservation bit set in the internal memory as shown in FIG. 12a is set in the internal memory by operation 130a described above, and thus the microcomputer 12 determines that the reservation bit is set in step 134a. From 10), search whether dial key is input.

If it is determined in step 154a that the dial key is not input, the microcomputer 12 of the second mobile device performs steps 136a to 142a of FIG. 7 which are the same as steps 136 to 142 of FIG. Search whether the end message data outputted at the end is received, and perform the same call reservation function as in FIG. 5 according to the reception state of the message.

If it is determined that the dial key is input in step 154a, the microcomputer 12 suits the dial digit data input from the key input unit 10 to the reserved dial buffer set as shown in FIG. 12c in step 156a. Repeat the operation.

If any mobile device transmits the call termination message data to the fixed device in the reservation state, the fixed device transmits the call termination message data to all mobile devices in response to the input of the call termination message data as described above. . At this time, the second mobile device receives the call termination message data transmitted from the fixed device through the receiver 24, and by receiving the end message, the microcomputer 12 of the second mobile device receives the 136a. In step 138a, it is determined that the end message data has been received, and in step 138a, the call possibility sound as shown in FIG.

At this time, when the user who listens to the call function presses the call key, the microcomputer 12 of the second mobile device performs the above steps 100a to 114a to output the call request data to the idle channel, and the response data is received. Find out if it works. If it is determined in step 112a that the response data is received, the microcomputer 12 of the second mobile device searches whether the reserved bit is set in the internal memory in step 144a.

If it is determined that the reserved bit is reset in the process, the general call mode is serviced as described above, and if it is determined that the reserved bit is set, the microcomputer 12 stores the dial digit in the reserved dial buffer in step 146a. Search for existence. If the dial digit is stored in the reserved dial buffer in step 146a, the microcomputer 12 transfers and stores the contents of the dial digit stored in the reserved dial buffer in the dial buffer as shown in FIG. 12d in step 148a. The dial digit stored in the buffer is transmitted through the transmitter 20, and the processes 118a to 126a are performed to perform the reserved call mode. At this time, the fixing device receives the dial digit transmitted as described above and transmits the corresponding dial signal to the telephone line.

Therefore, the user of the second mobile device that reserves the call hears that the fixed device can make a call as soon as the call is terminated with any portable device, and after pressing the call key, listens to the sound and presses the call key. The user's convenience can be maximized by forming a communication path and automatically transmitting the reserved dial signal.

[Third Embodiment: In the case where the fixed device capable of dialing and making a call and the fixed device makes a call reservation while the mobile device is in a call

The third embodiment according to the present invention will be described with reference to FIGS. 8 and 9.

If any portable device requests a call to the fixed device and the hook switch located in the key input unit 34 in the fixed device is off hooked by the user in a busy state as in the first or second embodiment, The microcomputer 32 in the fixing device controls the speakerphone control unit 54 to output a busy warning sound to the speaker 52.

When the call reservation key located in the key input unit 34 is pressed in the above state, the microcomputer 32 in the fixing device sets a reservation bit set in the memory 33 and simultaneously schedules down counting of a predetermined time. Run the timer to activate the reservation function.

When the reservation function is activated, the microcomputer 32 in the fixed device transmits the call termination response message data in response to the call termination message data when the call termination message data is transmitted from the mobile device within the time set in the reservation timer. The controller 54 is controlled to output the call function sound.

When the user who has heard the call available presses the hook switch installed in the key input unit 34 in the fixed device, the microcomputer 34 controls the line interface unit 46 and the network control unit 48 to provide the off hook service. To perform.

Therefore, the mobile device, which was in communication with the fixed device, can make an off-hook service as soon as the call ends.

The operation thereof will be described in detail with reference to the ninth embodiment.

The microcomputer 34 in the fixed apparatus searches for a call with the portable apparatus in FIG. If it is determined in step 160 that the mobile device is in a call, the microcomputer 34 performs a service call during the call with the mobile device and searches whether the off-hook key is input from the key input unit 34 in step 164. If it is determined in step 164 that the off-hook key is input, the microcomputer 32 of the fixing device controls the speakerphone controller 54 in step 166 to output a busy warning sound as shown in FIG. 13a, and in step 168, the key input unit 34. Search for reserved function key signal from.

When the user presses the reservation function key installed in the key input unit 34 in the above state, a signal of the reservation function key is input to the microcomputer 32, and the microcomputer 32 inputs the reservation function key in step 168. I think it is.

Drive. Here, the reservation timer decreases the preset time, which is the same as the above-described reservation timer.

In step 172, the microcomputer 32 of the fixed device that has driven the reservation timer searches whether the reservation bit is set in step 174. In this case, since the reserved bit set as shown in FIG. 12B is set in the memory 33 by the operation of the aforementioned process 170, the microcomputer 32 determines that the reserved bit is set in step 174. In the process, it is searched whether the reservation timer has completed counting the set time.

If the increase time of the reservation timer exceeds the preset time in step 176, the microcomputer 32 in the fixed device is increased in the memory 33 in step 178 to reset the reservation timer to release the advanced state. In step 180, it is checked whether call termination message data is received. However, if it is determined in step 176 that the reservation timer has not counted the predetermined time, the microcomputer 32 immediately searches whether the call termination message data is received in the call reservation state in step 180.

In the above description, the call termination message data is data transmitted by the fixed device and the portable device during the call.

If the end message data is not received in step 180, the microcomputer 320 repeats the process from step 162 described above.

When the mobile device, which is in communication with the fixed device in the above-described state, terminates the call and transmits the call termination message data, the call termination message data is input to the microcomputer 32 through the receiving unit 38 of the fixed device. In this case, the microcomputer 32 determines that call termination message data has been input in step 180.

The microcomputer 32 of the fixed device, which determines that the call termination message data has been input, controls the line interface unit 46 in step 182 to block the call line of the CO line and transmit the call termination message data to all mobile devices. In the process, it is checked whether the reserved bit is set. If the reservation bit is not set in step 184, the microcomputer 32 returns to step 160 to perform a normal operation. If the reservation bit is set, the microcomputer 32 controls the speakerphone controller 54 in step 186 to FIG. 13 (b). After outputting the available call as the speaker 52 and returns to step 160.

That is, if the reservation bit is set after the call termination response message data is output and it is determined that the current state is the call reservation state, the microcomputer 32 outputs a call possibility indicating that the reserved call can be made.

After transmitting the call termination response message as described above, the microcomputer 32 of the fixed device that performs the process 160 determines that the call with the portable device is terminated and scans the standby channel in step 188. In step 190, the controller 130 determines whether an off-hook key signal is input from the key input unit 34. If the off-hook key is not input in step 190, the process returns to step 160 and repeats the standby channel scan operation.

When the user who listens to the available call in the above operation state presses the off-hook key located in the key input unit 34, the signal thereof is input to the microcomputer 32, in which the microcomputer 32 processes 190. In step 192, the reserved bit is reset and the reservation is released.

In step 192, the microcomputer 32 in the fixed device that releases the reservation controls the line interface controller 46, the network controller 48, and the speakerphone controller 54 to service the off-hook. Here, the off-hook service means a state capable of transmitting and receiving a signal by forming a call with a trunk line (T, R).

In operation 194, the microcomputer 32 of the fixing device that performs the service for the off-hook searches for whether the hook key signal from the key input unit 34 is input in step 196. When the on-hook signal is input, in step 198, the transmission / reception 36 is controlled to transmit the call termination message data to all the mobile devices and return to step 160.

Therefore, the user of the fixed device that has reserved a call hears the available call immediately after the call between the mobile device and the fixed device ends. When the user who listens to the available call is off-hook, the call with the CO line is immediately made. By forming a furnace, you can make calls.

[Fourth embodiment: when a fixed device capable of dialing and a call and a mobile device perform automatic dialing while the fixed device reserves a call and stores a dial during a call]

In the above-described fourth embodiment according to the present invention with reference to Figs. 10 and 11, a description will be given on the assumption that a fixed device and an arbitrary portable device are in a call relationship as described in the third embodiment.

10 and 11 according to the fourth embodiment is a form in which a reservation dial digit storage function and a control process for automatically transmitting the dial digit when the call is formed as a reserved call are added to the third embodiment. Same as

Now, when a user is off-hook with the hook switch positioned in the key input section 43 in the fixed device while the mobile device and the fixed device are in a call, the microcomputer 32 in the fixed device has the speakerphone controller 54 as described above. ) To output a warning alert sound to the speaker 52.

When the call reservation key located in the key input unit 34 is pressed in the above state, the microcomputer 32 in the fixing device sets a reservation bit set in the memory 33 and simultaneously schedules down counting of a predetermined time. Run the timer. When a dial digit is input from the key input unit 34 in the reservation state, the microcomputer 32 in the fixed device stores the dial digit signal input in the reserved dial buffer set in the memory 33.

In the reservation state as described above, when the call end message data is transmitted from the portable device within the time set in the reservation timer, the microcomputer 32 transmits the call termination response message data in response to the call end message data. The speakerphone control unit 54 is controlled to output a call usable sound.

When the user listening to the call is pressed, the micro switch 34 controls the line interface unit 46 and the network control unit 48 by pressing the hook switch installed in the key input unit 34 in the fixed device. , R) forms a call path, transmits a dial digit signal stored in the memory 33 to the formed call path, and performs an off hook service.

Therefore, the mobile device, which was in communication with the fixed device, by means of the above call reservation, forms a communication path with the telephone line immediately after the call is terminated, and then transmits the reserved dial signal to perform off-hook service.

The operation thereof will be described in detail with reference to the eleventh as follows.

When the fixing device is operated, the microcomputer 32 in the fixing device performs the processes of FIGS. 11A through 160A to 172a of FIG. Therefore, when the fixing device is off-hook in a state where the fixing device and the portable device are in communication with each other, the microcomputer 32 in the fixing device is reserved in the memory 33 as described above with reference to FIG. 9 by the operations 160a to 172a. Set call reservation by setting bit.

The microcomputer 32 having set the call reservation as described above erases all contents by initializing the contents of the reserved dial buffer set in the memory 33 in step 200a.

In step 200a, the microcomputer 32 initializes the contents of the reservation dial buffer, and in step 174a, the reservation bit set in the memory is set to search whether the current state is a call reservation state.

If it is determined in step 174a that the current state is a reserved state, the microcomputer 32 searches whether the dial key is input from the key input unit 34 in step 202a. If the search result dial key is input, the microcomputer 32 stores the digit corresponding to the dial key input in step 204a in the reserved dial buffer set as shown in FIG. 12 (C). In step 176a, it is checked whether the preset time has been counted. If the dial key is not input in step 202a, step 176a is immediately performed.

The microcomputer 32 performing the process 176a performs the reservation call service according to the reservation state by performing the processes of FIGS. 11 through 178a through 186a which are the same as the processes of FIGS. 9 through 178 through 186 of FIG. 9. For example, if the end data is received within a preset reservation control time, the caller 52 is output to the speaker 52, and the above process 160a is repeated, and if the end data is not received within the reservation time limit, the reservation is made. After the call is released, the above process 160a is repeatedly performed.

After the call termination response message is transmitted as described above, the microcomputer 32 of the fixed device performing the process 160a determines that the call with the portable device is terminated as described above, and scans the standby channel in step 188a. . In operation 190a, it is searched whether an off hook key signal is input from the key input unit 34. If the off-hook key is not input in step 190a, the process returns to step 160a and repeats the standby channel scan operation.

When the user who listens to the available call in the above operation state presses the off-hook key located in the key input unit 34, the signal thereof is input to the micom 32 as described above, and at this time, the micom 32 ) Determines that it is off-hooked in step 190a, and searches whether the reserved bit set in the memory 33 is set in step 206a.

If it is determined in step 206a that the reserved bit is set, the microcomputer 32 searches whether the digit is stored in the reserved dial buffer set in the memory 33 in step 208a.

If it is determined that there is a stored digit in step 208a, the microcomputer 32 copies the dial digit stored in the reserved dial buffer in step 210a into the dial buffer. In operation 212a, the microcomputer 32 of the fixing device writes the dial digit stored in the dial buffer to the electronic dial generator 42. At this time, the electronic dial generator 42 outputs an electronic dial signal DTME corresponding to a digit output from the microcomputer 32, and the signal is transmitted through the network controller 48 and the line interface controller 46. Output to trunk line (T, R).

The microcomputer 32 which transmits the stored dial digit in step 212a releases the reservation state by resetting the reserved bit in step 192a, and performs steps 1194a to 198a of FIG. Perform a call service.
