Abstract

PURPOSE:To utilize a polling function in all terminals by specifying polling information to request the polling function to a sub address and executing an operation as the incoming call of the polling function request when the polling information is specified to the sub address. CONSTITUTION:When an event to request the call of communication is generated in the terminal and the event is a polling reception request, the specified sub address allocated for polling communication is set to the sub address and a call request is executed from a communication control part 12 and a network control part 13 through an ISDN line 14. Then, the reception of a response to this call is waited and when an incoming call is the response, transmission data to the polling request are received from the incoming terminal.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a communication terminal device, and relates to an integrated digital network (ISD).
N:Integrated 5 services Dig
The present invention relates to a communication terminal device that is connected to the Internet Network and has a polling function.

[Prior Art] Conventionally, as a communication terminal device having a polling function,
For example, there is a G4 facsimile machine, and its polling function is such that a document to be sent is set in advance on the polling sending side, and in response to an incoming call request from the polling receiving side, both the sending and receiving terminals send a message after the line is connected. - When exchanging reception capabilities, if a polling identifier is set, the set document is configured to be transmitted.

[Problems to be Solved by the Invention] However, in the above conventional example, the request for the polling function is made for the first time when transmitting and receiving capabilities are exchanged after the line is connected, so even if the polling function is not possible, the line is not connected. The disadvantage was that it required extra charges.

Furthermore, since there is no unified standard for the specifications of the polling function, which is exchanged based on transmission and reception capabilities, there is also the drawback that the polling function can only be implemented between communication terminals having the same specifications (for example, within the same manufacturer).

The present invention is based on the above; i! ! ! This was created to solve the problem, and it provides a communication terminal device that can use the polling function on all terminals, not the same terminal model, and does not incur extra charges if the polling function is not available. The purpose is to

[Means and operations for solving the problems] In order to achieve the above object, the communication terminal device of the present invention has the following configuration. That is, a communication terminal device is connected to a network system in which a plurality of communication terminal devices are connected to at least one line, a sub-address for identifying each communication terminal is added to a subscriber number, and the communication terminal device has a polling function. , specifying means for specifying polling information that requests a polling function for the sub-address, and transmitting means for transmitting the sub-address including the polling information specified by the specifying means;
A receiving means for receiving a sub-address including the polling information, and a discriminating means for discriminating the sub-address received by the receiving means, and if polling information is specified in the sub-address by the discriminating means, a polling function request is received. It works as.

Preferably, the determining means operates to reject the incoming call by setting the rejecting means to reject the response to the incoming call if polling transmission as a polling function is not possible.

[Embodiment] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Consists of M. A buffer memory 10 stores image data read from the reader 2, and the like. 11 is a code/decoder unit that compresses or expands data. 12 is a communication control unit that performs protocol control of the high-level polishing function. 1
3 is a network control unit that performs protocol control of the low-level polishing function. Number 14 is an ISDN line.

Description of Operation (FIGS. 2 to 4)> The operation of the present apparatus having the above configuration will be explained below with reference to FIGS. 2 to 4.

Note that FIG. 2 is a flowchart showing the control procedure at the time of receiving an incoming call in this embodiment, and FIG. 4 is a flowchart showing the control procedure on the calling side.

Further, FIG. 3 is a diagram showing the structure of the ISDN number in this embodiment. As shown in the figure, the ISDN number 3o is composed of a line identification 31, a domestic subscriber number 32, and a subaddress 33. The sub-address 33 includes a sub-address data identifier 34 and a sub-address data length 3.
5, subaddress data 35.

First, in step S40 shown in FIG. 4, when a communication call request event (for example, activation by an operator's instruction or a specified time) occurs in the terminal, it is determined whether the call request event is a polling reception request or not. Determine. As a result, if it is not a polling reception request, the process proceeds to step S41, and normal calling communication processing is executed. However, if the determination result is a polling reception request, in step S42, a specific subaddress allocated for polling communication is set in the subaddress 33 shown in FIG. A call request is made via 14.

Then, in step S43, a response to this call is waited for, and if a response is received, the process advances to step S44,
Judge the response. As a result, if the called party refuses to respond to the polling request, the calling process is terminated without connecting the line.

However, if it is a response to the incoming call, the process advances to step S45, and data sent in response to the polling request is received from the called terminal.

First, in step S20 shown in FIG.
When the network control section 13 receives an incoming call request from the other party's terminal via the line 14, it notifies the CPU of the microprocessor section 9 of the incoming call through the communication control section 12. Upon receiving the call, the CPU advances the process to step S21, and determines whether the subaddress 33 included in the call request command matches the specific subaddress assigned for polling communication. As a result, if they do not match, step S2
2, the communication processing in the conventional I5DN communication terminal device is performed. However, if the sent subaddress 33 matches the value of the specific subaddress assigned for polling communication, the process proceeds to step 323, and the transmission is sent to the other party terminal that sent the polling request to this terminal device. Determine whether there is data that should be used. As a result, if there is no data to be transmitted, the process advances to step S24, and the network rejects the response to the incoming call.

This allows the other party's terminal to know that the polling request has been rejected and to end the communication without connecting the line.

Note that the determination process in step S23 described above is performed by, for example,
In the case of a G4 facsimile machine, this is a process of checking via the reader control section 6 whether or not a transmission document is set in the reader 2 .

On the other hand, if there is data to be transmitted, the process advances to step S25, and the communication control unit 12 is instructed to transmit an incoming call response. In response to this instruction, the communication control section 12 connects the line according to the I5DN call setting procedure, and when the line is connected, the transmission manuscript is read from the reader 2 via the league control section 6. Then, the code/decoder 11 encodes the data of the read document into code data for the other party's terminal, sends out the encoded transmission data, and finishes the polling transmission process.

According to this embodiment, by accepting all incoming calls to a specific sub-address as polling request iM calls, the following effects can be achieved.

(1) As long as there is a communication terminal connected to an ISDN line and a subaddress can be specified, polling requests can be made from all terminals, not just those of the same model.

(2) If the polling request cannot be accepted (for example, there is no data to send), a rejection response can be sent to notify the other terminal of the polling transmission rejection, and no extra charges will be incurred.

[Effects of the Invention] As explained above, according to the present invention, the polling function can be used not only in the same terminal model but also in all terminals, and when the polling function is not available, communication costs can be reduced. .
