FIGS. 7 and 8 are flowcharts showing the operation of the private branch exchange 101 in the above embodiment, that is, flowcharts showing the operation of the control unit provided inside the private branch exchange.

First, in step S501 shown in FIG. 5, the facsimile apparatus (radio) 109
03 and the wireless channel are connected, and the private branch exchange 101,
It is assumed that G3 facsimile transmission is being performed via the outside line 110. That is, according to ITU Recommendation T. 4, T. It is assumed that normal G3 facsimile transmission is being performed in accordance with No. 30.

Then, in step S502, the user operates the facsimile apparatus (wireless) during facsimile transmission.
When the “telephone reservation” button on the operation panel 304 of the 109 is pressed, the facsimile apparatus (wireless) 109 operates the telephone reservation function thereafter. Here, the user can input a number for specifying the local wireless terminal desired to be used in “telephone reservation”, for example, an extension number.

On the other hand, if the user does not press the "telephone reservation" button in step S502, the facsimile apparatus (wireless) 109 performs a normal facsimile procedure in step S503 and ends the operation.

The operation of the telephone reservation function is as follows.
At 504, the facsimile apparatus (wireless) 109
After transmitting all or a part of the facsimile transmission data, ITU recommendation T.1, which is a user calling signal, is transmitted to the other party's facsimile apparatus. A PRI-Q signal specified in No. 30 is transmitted to notify the other party facsimile machine that "telephone reservation" has been made. The other party's facsimile machine
When the PRI-Q signal is received, a ringing sound such as a beep sound is emitted from a speaker or the like to call the user.
When the user picks up, for example, an attached telephone at the other party's facsimile apparatus, the other party's facsimile apparatus transmits a response signal (PIP signal or PIN signal) to the facsimile apparatus (wireless) 109.

Here, the other party's facsimile machine and its attached telephone may be connected by a wireless channel and have a "telephone reservation" function employing the method of the present invention.

In step S505, facsimile apparatus (wireless) 109 waits for reception of a PIP signal or a PIN signal sent from the other party's facsimile apparatus.

Here, in step S506, the timer is counted. For example, when the user does not pick up the attached telephone at the other party's facsimile machine, the PIP
No PRI-Q signal or PIN signal is received.
The signal is transmitted twice at a predetermined fixed time interval, and the PI
If the P signal or the PIN signal has not been received, a normal facsimile procedure is performed in step S503, and the operation of the facsimile apparatus (wireless) 109 of the above embodiment ends.

On the other hand, in step S505, the PIP
Upon receiving the signal or the PIN signal, facsimile apparatus (wireless) 109 determines that the user of the other party's facsimile apparatus has picked up the telephone or the like, and starts an operation of calling the local wireless terminal on this side.

Specifically, in step S507,
First, a search is performed to determine whether or not a number specifying the local wireless terminal to be called has been entered. That is, the above step S5
In 02, if the user presses the “telephone reservation” button on the operation panel 304 and then inputs the extension number of the local wireless terminal to be connected by the “telephone reservation” function, the input is made in step S508. An extension number information is added, a "wireless terminal call" signal is generated, and a "wireless terminal call" signal is transmitted to the private branch exchange 101 via the wireless base station 103 through the wireless channel. Here, the “wireless terminal paging” signal includes an associated control channel (ACCH; Associated ControlChannel, more specifically, FACCH; FastACCH or SACCH) based on the TDMA / TDD scheme.
Command data indicating a wireless terminal call using Slow ACCH) and extension number data of the local wireless terminal to be called, which is input by the facsimile apparatus (wireless) 109.

[0065] Radio base station 103 receives this and outputs it to private branch exchange 101. If necessary, the wireless base station 1
03 converts the call switching request signal into an appropriate format.

On the other hand, if the facsimile machine (wireless) 109 determines in step S507 that the user has not entered the number specifying the local wireless terminal to be called, then in step S509 the facsimile machine (wireless) A search is made as to whether or not the information is registered in advance in 109. That is, the user can pre-register the number of a specific local wireless terminal to be connected at the time of the "telephone reservation" function operation at the time of initial setting of the facsimile apparatus (wireless) 109 or before performing facsimile communication. Is R
It is stored in the AM 303.

Then, it is searched here whether or not the number data is registered. If registered, the process proceeds to step S510. If not registered, it is determined that there is no data specifying the local wireless terminal to be called, and the process proceeds to step S511.

In step S510, facsimile apparatus (wireless) 109 adds the registered extension number information to generate a "wireless terminal call" signal, and transmits wireless base station 103 through wireless channel in the same manner as described above. Then, a “wireless terminal call” signal is transmitted to the private branch exchange 101.

In step S511, the facsimile apparatus (wireless) 109 generates a "wireless terminal call" signal without adding extension number information, and, similarly to the above, passes through the wireless channel and the wireless base station 103. A “wireless terminal call” signal is transmitted to the private branch exchange 101.

Then, in step S512, facsimile apparatus (wireless) 109 waits for reception of a "call response" signal from private branch exchange 101 through wireless base station 103. Upon receiving the "call response" signal, the facsimile machine (wireless) 109 determines that the calling local wireless terminal 103 has responded to the private branch exchange 101, and proceeds to step S513.
In step (1), a PRI-Q signal indicating that the user on the local side can go out to the local wireless terminal 103 and make a call is transmitted to the other party's facsimile apparatus.

Here, the "call response" signal corresponds to the TDM signal.
This is status data indicating information such as the extension number of the local wireless terminal in response to command data indicating a call response using an associated control channel based on the A / TDD method.

Therefore, the facsimile apparatus (wireless) 1
09 analyzes information such as the extension number of the responding local wireless terminal included in the “call response” signal, identifies the responding local wireless terminal, and identifies it by an LCD or the like provided on the operation panel 304. The information can be displayed or printed out by the recording unit 306, so that the user can confirm it, and the connection to the local wireless terminal is more reliable, and the usability is further improved.

Then, in step S 514, through the wireless base station 103 and the private branch exchange 101 so far,
Since the private branch exchange 101 connects the information channel connected to the facsimile apparatus (wireless) 109 with the other party's facsimile apparatus to the local wireless terminal that has responded, the channel on the facsimile apparatus (wireless) 109 side is disconnected.
Thus, the facsimile apparatus (wireless) 10 of the above embodiment
The operation of No. 9 ends.

On the other hand, if no call response is received in step S512, the facsimile apparatus (wireless) 109 monitors in step S515 whether a "number invalid" signal is received from the private branch exchange 101. Here, the private branch exchange 101 is a facsimile apparatus (wireless) 1
The extension number in the “wireless terminal call” signal received from the telephone number 09 is checked, and if it is determined that the number is not registered in the private branch exchange 101 and is incorrect, a “number invalid” signal is generated and the facsimile apparatus (wireless ) 109. Here, upon receiving the “number invalid” signal, the facsimile apparatus (wireless) 109 displays a message indicating invalid input on the LCD of the operation panel 304 or blinks an LED indicating caution in step S516. By using the recording unit 306, an error report is output to notify the user of the invalid input. Then, in step S503, the normal facsimile procedure is performed, and the operation of the facsimile apparatus (wireless) 109 of the above embodiment ends.

On the other hand, if the "number invalid" signal is not received in step S515, the facsimile apparatus (wireless) 109 sets the private branch exchange 1 in step S517.
It monitors whether or not a “No Response” signal is received from 01.
Here, the private branch exchange 101 calls the private wireless terminal and monitors a timer. If the private wireless terminal does not respond at all, the private branch exchange 101 times out, generates a “no response” signal, and sends the signal to the facsimile apparatus (wireless) 109. Send.

Here, the facsimile apparatus (wireless) 109
Receives the "no response" signal, in step S516, displays a message indicating no response to the local wireless terminal, blinks an LED indicating caution, or uses the recording unit 306 on the LCD of the operation panel 304 in step S516. And Notify the user of no response by outputting an error report. Then, in step S503, the normal facsimile procedure is performed, and the operation of the facsimile apparatus (wireless) 109 of the above embodiment ends.

On the other hand, in step S512, facsimile apparatus (wireless) 109 starts a timer and waits for the reception of a call response from private branch exchange 101. In step S515, it monitors a number invalid signal, and in step S517, The non-response signal is monitored, but is not received. When the timer times out in step S518, the monitoring of the reception of the call response, the reception of the invalid number signal, and the reception of the non-response signal is stopped.
At 6, the user is notified of the fact.

That is, as described above, the facsimile apparatus (wireless) 109 uses the LCD of the operation panel 304 to display a message indicating that the private branch exchange has not responded,
The user is notified that the private branch exchange has not responded by blinking an LED indicating a caution or outputting an error report using the recording unit 306. Then, in step S503, the facsimile apparatus (wireless) 109 performs the normal facsimile procedure, and the operation of the facsimile apparatus (wireless) 109 of the above embodiment ends.

On the other hand, the operation of the private branch exchange 101 is shown in FIG.
In step S601 of FIG. 8, first, the information channel is being connected to the facsimile apparatus (wireless) 109 via the wireless base station 103, and the facsimile apparatus (wireless) 109
Is in communication (in this case, transmission).

In this case, in step S602,
Facsimile machine (wireless) 109 to wireless base station 103
And monitors the reception of the "wireless terminal call" signal.

When private branch exchange 101 receives the “wireless terminal call” signal, in step S 603,
The signal is analyzed, and a search is performed to determine whether or not the “wireless terminal call” signal includes an extension number designating the local wireless terminal to be called. If the extension number is included, step S
At 604, a search is made as to whether the registered extension number specifying the local wireless terminal to be called is correct.

That is, for example, three private wireless terminals 103, 104, and 105 are registered to be connected to the private branch exchange 101 wirelessly via a wireless base station.
What are those extensions? If the numbers are 01, 02, and 03, respectively, those numbers are registered in the private branch exchange 101 in advance and stored in the control unit. If the “wireless terminal call” signal received from the facsimile apparatus (wireless) 109 contains the extension number information of the private wireless terminal to be called, the information is stored in the control unit of the private branch exchange 101. Check the data with If the collation result is found, the private branch exchange 101 identifies one of the available private wireless terminals.
The process proceeds to step S607.

For example, an incorrect extension number, for example, 0
If the private branch exchange 101 is included, the private branch exchange 101 recognizes this and notifies the facsimile apparatus (wireless) 109 of the fact in step S605. That is, the private branch exchange 101 generates a “number invalid” signal, transmits the “number invalid” signal to the facsimile apparatus (wireless) 109 via the wireless base station 103 and the wireless channel.

Here, the "number invalid" signal is command data indicating the number invalid using the associated control channel based on the TDMA / TDD system as described above. To the "number invalid" signal, an invalid extension number included in the "wireless terminal calling" signal sent from the facsimile apparatus (wireless) 109 may be added for identification. Thus, the operation of the private branch exchange 101 of the above embodiment ends.

On the other hand, in step S 603, the “wireless terminal call” signal is analyzed, and if the extension number designating the local wireless terminal to be called is not included, the process proceeds to step S 606.
In, a search is made as to whether one extension number designating the private wireless terminal to be called is registered in the private branch exchange 101 in advance.

That is, the user can pre-register the number of a specific private wireless terminal to be connected at the time of the "telephone reservation" function operation at the time of initial setting of the private branch exchange 101 or before performing facsimile communication. Is the private branch exchange 1
01 is stored in the control unit. Here, whether or not the number data is registered is searched here. if,
If registered, the process proceeds to step S607. If not registered, it is determined that there is no data specifying the local wireless terminal to be called, and the process proceeds to step S611.

Here, first, it is searched whether or not the number of the local wireless terminal to be called is transmitted from the facsimile apparatus (wireless) 109, and if not, it is searched whether or not it is registered in the private branch exchange 101. The priority of the number input in the device (wireless) 109 is higher. If it is desired to reverse the priority, the control in step S603 and step S606 may be reversed.

In step S607, private branch exchange 1
01 calls a specified specific private wireless terminal. Here, it is assumed that the number 02 specifying the private wireless terminal has been input or that the private wireless terminal 1 has been registered in advance.
06 is called. That is, the private branch exchange 10
1 transmits a paging signal including the number 02 to the wireless base station 103, the wireless base station 103 identifies it, establishes a link channel and a service channel with the local wireless terminal 106, and exchanges a call setup message. I do.

Then, in step S608, private branch exchange 101 responds to the call setup message (CONNE
When receiving the CT) from the local wireless terminal 106 through the wireless base station 103, it is determined that the user of the local wireless terminal 106 has responded, and in step S609, the facsimile apparatus (wireless) 109 is transmitted through the wireless base station 103.
Send a "call response" signal.

Here, since the "call response" signal includes status data indicating information such as the extension number of the responding local wireless terminal, the facsimile apparatus (wireless) 109 analyzes it and transmits the local wireless terminal which has responded. Identification and display it on an LCD or the like on the operation panel 304, or the recording unit 30
For example, if the user prints out the print data according to 6, the user can confirm the printout, the reliability is increased, and the usability is further improved.

Then, in step S610, private branch exchange 101 disconnects the information channel connected to facsimile apparatus (wireless) 109 with the other party facsimile apparatus via wireless base station 103 and private branch exchange 101 so far. Then, it connects to the local wireless terminal 106 that responded.
Therefore, the user of the local wireless terminal 106 can talk with the user of the partner terminal. Here, if the public line 308 is the PSTN, the communication control unit 307
Does not disconnect the call because the DC loop is still formed with the line. Also, if the public line 308 is IS
If it is a DN, the communication control unit 307 keeps the connection between the line and the D channel, so that this connection is not disconnected. Thus, the operation of the private branch exchange 101 of the above embodiment ends.

On the other hand, in step S611, the private branch exchange 101 calls all the private wireless terminals to be connected.
In this case, since three local wireless terminals 103, 104, and 105 can be connected, all of them are called by the simultaneous incoming call method. That is, a command is transmitted to the wireless base stations 102, 103 and 104 so that the private branch exchange 101 outputs an incoming call (all PS calls) to each private wireless terminal.

Then, in step S608, if one of the local wireless terminals that has called the paging responds (here, the local wireless terminal 106 responds), the local wireless terminal 106 sends a link channel establishment request. The base station 103 allocates a link channel to the private wireless terminal 106, sets up a call, and notifies the private branch exchange 101 that the private wireless terminal has responded. Private branch exchange 101
Receives the notification, determines that the local wireless terminal has responded, and as described above, steps S609 and S610
Is performed, and the operation of the private branch exchange 101 of the above embodiment ends.

Here, since the "call response" signal includes status data indicating information such as the extension number of the responding local wireless terminal, the facsimile apparatus (wireless) 109 analyzes it and responds to the local wireless terminal. Is identified and displayed on an LCD or the like on the operation panel 304, or the recording unit 3
06, it is possible to print out, and the user can confirm it, and the usability is further improved.

However, if the private branch exchange 101 recognizes that there is only one private wireless terminal to which the private branch exchange 101 is connected in step S611, it is possible to eliminate the need for calling in the simultaneous incoming call system. As described above, the facsimile apparatus (wireless) 109 may establish a link channel and a service channel with the local wireless terminal 103, exchange a call setup message, and make a call. Then, when the private branch exchange 101 receives a response (CONNECT) of the call setting message from the called local wireless terminal, it determines that the user of the private wireless terminal has responded.

On the other hand, in step S608, private branch exchange 101 starts a timer and waits for reception of a response from the called private wireless terminal, but when no response is received, that is, a response (CONN) from private wireless terminal 106.
If ECT) is not received, or if a link channel establishment request is not received from the paging wireless terminal that has called the paging simultaneously, in step S612, if the timer times out, the local wireless terminal returns to the terminal due to the absence of a user or the like. Judge not responding.

In step S613, the facsimile apparatus (wireless) 109 is notified of the fact. That is, a "no response" signal is generated, passed through the radio base station 103, passed through a radio channel, and sent to a facsimile apparatus (wireless).
A “no response” signal is sent to 109. Here, the "no response" signal is command data indicating no response using the associated control channel based on the TDMA / TDD system. Thus, the operation of the private branch exchange 101 of the present embodiment ends.
