Abstract

PURPOSE:To make plural persons answerable by using one's own sub-addresses through one communication terminal equipment by previously registering personal sub-address information in an external memory, such as an ID card, etc., and opening the terminal equipment when sub-address information contained in incoming signals coincides with the personal sub-address information read from the external memory. CONSTITUTION:This communication terminal equipment is constituted of an external sub-address reading section 5 which reads an external memory M composed of an ID card in which personal sub-address information is registered and sub-address comparing section 6 which compares sub-address information contained in incoming signals of the section 5 with the personal sub-address information read out from the external memory. The equipment makes a call only when it is discriminated that the sub-addresses coincide with each other as a comparing result of the section 6. Thus the communication terminal equipment can be used as terminal equipment having peculiar sub-addresses set by personal ID cards.

Description

Detailed Description of the Invention (Objective of the Invention) (Industrial Application Field) The present invention relates to a communication terminal connected to a line of an integrated digital service network (hereinafter referred to as 15DN), and in particular,
The present invention relates to a control method for an 15DN terminal in which a subaddress is dynamically set using an external memory such as a 10 card.

(Prior art) In a communication terminal device connected to an ISDN line, by specifying a subaddress in addition to the subscriber number, it is possible to specify the terminal to which a transmission is desired from among multiple terminals connected to a bus to the network terminal device. It looks like this.

This type of device is configured such that once a subaddress is set, the subaddress of the terminal will not be changed.

However, in such a device, if an attempt is made to change the subaddress, the terminal must be replaced.

(Problems to be Solved by the Invention) However, in the conventional device described above, since the terminal is fixed to one sub-address, there is a problem that it is not possible to have a sub-address as a personal number.

Therefore, in order to allocate a subaddress to each individual, a dedicated terminal for that individual was required.

However, there is a limit to the number of terminals that can be bus-connected to one network termination device due to cost and installation space considerations.

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a communication terminal that can be used by a plurality of people, each of whom has a unique sub-address.

(Structure of the Invention) (Means for Solving the Problem) Therefore, in the present invention, [in the communication terminal connected to the SDN, personal 4)-B address information is registered in an external memory such as a [0 card]. At J3, if the sub address information included in the incoming call signal matches the personal sub address information read from the external memory, the communication terminal is opened.

(Operation) With the above configuration, one terminal can be used by a plurality of people by registering personal sub-address information in an external memory such as an ID card and inputting this sub-address information from the outside.

That is, since the subaddress can be set as a personal number, each individual can use their own subaddress from any communication terminal.

(Example) Hereinafter, examples of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of a communication terminal g according to an embodiment of the present invention.

This communication terminal device includes a main control section 1 that controls the operation of the entire device, an operation key 2 for giving operation instructions to the main control section 1, and an 15DN line network 10.
a transmission unit 3 that transmits an incoming signal from the incoming call, a subaddress record 1 part 4 that extracts and temporarily stores subaddress information included in this incoming signal, and an external memory M consisting of an ID card in which subaddress information of four people is registered. It is composed of an external sub-address reading section 5 for reading, and a sub-address comparison section 6 for comparing the sub-address information included in this incoming signal with the personal sub-address information read from the external memory. The call is made only when the subaddresses match according to the results. Here, 7 is a telephone section and 8 is a handset.

Next, the operation at the time of receiving a call in this communication terminal device is explained as follows.
This will be explained with reference to the flowchart shown in the figure.

First, when an incoming signal from the transmitting side is input to the transmission unit 3 via the 15DN 10, the main control unit 1 determines whether or not a subaddress is added to this incoming signal. If so, this subaddress information is temporarily stored in the subaddress storage section 4 (step 110).

On the other hand, the subaddress stored in the ID car 1M that is marked @ is read by the external subaddress reading section 5 (subroutine 120).

Then, the sub-address comparator 6 compares the sub-address information included in this incoming signal with the personal sub-address information read from the external memory, and determines whether they match (step 130).

If it is determined in step 130 that they match, the terminal enters call processing (step 140).
.

On the other hand, if it is determined in this judgment step 130 that there is no match, this flow is terminated without receiving a call at the terminal in question, and the call processing starts when another terminal matches the call.

Furthermore, if it is determined in judgment step 100 that subaddress information is not included in the incoming signal, all terminals with the same subscriber number including the terminal in question are Incoming call processing is entered (step 140).

Next, the read external sub-address subroutine 120 for reading sub-addresses from external memory will be described with reference to the flowchart of FIG.

First, the main control unit 1 determines whether an external memory is installed (step 121).

If it is determined in this judgment step 121 that an external memory is installed, the external sub-address reading section 5 reads sub-address information from this external memory (
Step 122).

On the other hand, if it is determined in step 121 that no external memory is installed, an initial sub-address is set (step 123), and the communication terminal responds as the communication terminal of the sub-address originally held by this communication terminal.

As described above, according to the communication terminal according to the embodiment of the present invention, it is possible to perform an R5 response as a communication terminal having a unique sub-address set by an individual's ID card. Therefore, this communication terminal can be shared by multiple people as communication terminals each having a different sub-address.

[Effects of the Invention] As explained above, according to the communication terminal of the present invention, each individual has his or her own sub-address using external memory. In addition to being able to set each person's sub-address from a terminal, multiple people can respond with each person's sub-address using one terminal.
