Abstract

PROBLEM TO BE SOLVED: To obtain an ISDN terminal which distinguishes a sending number from an incoming call of a message and notifies it by efficiently identifying between the sending number and the message with a simple structure and also performing different signaling processing. SOLUTION: A signal which stores a sending number that is represented with a numeric character code or a message that is represented with a character code in an ISDN sub address area is inputted to a sub address identifying means 103 through a network interface circuit 102. When a first one code of a received ISDN sub address is a numeric character code, the means 103 decides that a sending number is stored and when it is a character code, it decides that a message is stored. When it is decided that a sending number is stored in the received ISDN sub address area, a speaker 105 performs 1st signaling processing, and when it is decided that a message is stored, the speaker 105 performs 2nd signaling processing.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal device used in an integrated services digital communication network (hereinafter, referred to as ISDN), and more particularly to an ISDN terminal device for performing communication by placing a calling number and a message on an ISDN subaddress.

[0002]

2. Description of the Related Art In an information communication network, a message is transmitted and received between specific terminals specified by a user.
A function to identify individual terminals is required. For example, a telephone number is used as a user terminal identifier of a telephone network. FIG. 11 illustrates the ISDN number structure (which is internationally standardized as an ITU-T recommendation). The ISDN number structure includes a country code 1101, a national code or a city office number 1102, User number 1103 and sub address 1104. The telephone number is used as a subscriber number in the ISDN domestic number, and is an identifier for identifying a subscriber terminal.

[0003] Although the basic framework of the ISDN number structure is determined by the ITU-T, the ISD-T
The subaddress following the ISDN international number in the N number structure can be freely used not only by the telecommunications carrier but also by the user.

As a prior art using this subaddress, for example, Japanese Patent Laid-Open No. Hei 5-167651 discloses that a calling number for specifying a caller is registered in a subaddress, and the calling number is transmitted to a receiving terminal. A means for identifying a caller by comparing the caller ID with a plurality of caller numbers registered in the above is disclosed. According to this technique, a terminal device connected to an ISDN via a basic interface compares a storage circuit in which a calling number or the like of a caller is registered with number information included in call setting information received at the time of an incoming call from the ISDN. The comparison circuit changes the ring tone according to the comparison result in the comparison circuit.

[0005] Japanese Patent Application Laid-Open No. 250552 discloses a technique of storing a calling number in a sub-address area and calling and displaying a calling party by searching a telephone directory of a terminal.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 of the Invention Embodiment 1 of the present invention will be described below. FIG. 1 is a block diagram of Embodiment 1 of the present invention. The terminal of the present invention includes a network interface circuit 102 connected to an ISDN line 101, a subaddress identification means 103 for identifying a calling number or message stored in a subaddress of a received signal, and a display unit for displaying the calling number or message. 104 and a speaker 10 for notifying that there is an incoming call
5 and storage means 106 for storing a calling number or a message stored in the ISDN sub-address, which are mutually connected via a bus 108 and whose operation is controlled by a main control unit 107.

The sub-address identification means 103 analyzes the sub-address according to the flowchart shown in FIG. 2 and identifies whether the information stored in the ISDN sub-address of the received signal is a calling number or a message. The speaker 105 is a notifying unit for notifying the user that a calling number or a message has been received. As shown in the flowchart of FIG. 3, the speaker 105 turns off the notifying process according to the incoming time (hereinafter, referred to as a flowchart). It can be referred to as “time limit of notification processing” (same in FIG. 3). When the calling number is stored in the ISDN sub-address, the speaker 105 emits a dial tone to notify the recipient that the calling number has been received (hereinafter referred to as “first number”).
If the message is stored, a tone different from that of the first notification process is issued to notify the recipient that the message has been received (hereinafter, referred to as the first notification process).
"Second notification process"), the user can be notified that either the calling number or the message has been received.

In the terminal according to the first embodiment of the present invention, IS
A signal in which a calling number represented by a numeric code or a message represented by a character code is stored in a DN subaddress area is received. The received signal is input from the ISDN line 101 to the sub-address identifying means 103 via the network interface circuit 102, and the information stored in the sub-address area is analyzed. In this case, for example, an IA5 character code is used as a numeric code or a character code representing the calling number or message stored in the sub-address area. In this case, in the present invention, when the calling number or the message is stored in the ISDN sub-address area, the entire ISDN sub-address area can be used for the calling number or the message. That is, STX, EO
There is no need to use a control code such as T.

In order to explain this point in detail, the ISDN subaddress analysis processing on the receiving side will be described with reference to FIG. The called terminal extracts the code contained in the received ISDN subaddress area in the subaddress identification means 103 (step 201). Then, the first one code of the extracted information is compared with the IA5 character code, and when it is determined that the code is a character code (NO in step 202), all codes included in the ISDN sub-address area are deleted. Judge as a character code. On the other hand, the first one of the extracted information
The code is compared with the IA5 character code, and if it is determined that the code is a numeric code (YES in step 202), all codes included in the ISDN sub-address area are determined to be numeric codes. in this way,
According to the embodiment of the present invention, when the receiving terminal analyzes the numbers or character codes included in the received ISDN sub-address area, all the codes are I-coded.
There is no need to compare with the A5 character code, so
A system can be easily created.

If it is determined in step 202 that the first code is a numeric code (YES in step 202).
In the case of S), the process proceeds to step 203. In step 203, the speaker 105 performs a first notification process to notify the user that the calling number has been received. However, the volume and sound quality of the ringtone in the first notification process are as follows:
The user can set it appropriately. In addition, in order to store the received calling number, a numerical code representing the calling number included in the ISDN subaddress is stored in the storage unit 107. The display unit 104 is controlled by the main control unit 107.
The calling number can also be displayed on the display. On the other hand, if the first code is a character code in step 202 (NO in step 202), step 2
Go to 04. In step 204, the speaker 105 performs a second notification process to notify the user that the message has been received. The second notification processing is performed by the first notification processing.
This is a notification process that emits a dial tone different from the notification process described above, so that the user can distinguish between the calling number and the reception of the message. The volume and sound quality of the ringtone in the second notification process can be appropriately set by the user. Then, under the control of the main control unit 107, the ISD
All the character codes included in the N subaddress are stored in the storage unit 107. Also, under the control of the main control unit 107, the display unit 104 can display the received message. Thereby, the user can easily identify whether the incoming call requires a response or the incoming call does not require a response. Further, the first and second notification means enable the user on the receiving side to easily determine whether the sender puts the calling number or the message on the ISDN subaddress, thereby improving the convenience of the terminal. Can be enhanced. Further, the code of the calling number and the code of the message are separately stored in the storage unit 106 under the control of the main control unit 107. When the first or second notification processing is completed, the process proceeds to step 205, where the ISDN subaddress analysis processing on the receiving side is terminated.

In the first or second notification processing by the speaker 105, the notification processing can be turned off according to a time set in advance by the user. This will be described with reference to FIG. FIG. 3 shows that, on the receiving side,
It is a flowchart at the time of notifying a notification process according to an arrival time.

In step 301, if the user sets a time limit for the first notification process, the user goes to step 3
02 (in the case of YES in step 301). In step 302, the user inputs a time at which the time of the first notification process is to be limited. The speaker 105 can turn off the first notification process according to the time zone set in the time setting. For example, when you are in a train or during a meeting, you cannot answer calls,
Alternatively, in a case where a call causes annoyance to surrounding people, the notification process of the speaker 105 can be turned off.

Similarly, the second notification process can be limited in time. That is, in step 303, when the user limits the time of the second notification process, the process proceeds to step 304 (in the case of YES in step 303),
Set the time. Thus, the second notification process of the speaker 105 can be turned off at the time set in step 304.

Further, the first or second notification processing is performed in the OF
If F, the user cannot know audibly that the calling number or message has been received. Therefore, by storing the calling number or the message in the storage unit 106, the user can confirm the calling number or the message after the fact.

As described above, according to the first embodiment of the present invention, transmission / reception of a simple message and accumulation / reception of information in the absence of the terminal can be performed without adding a special device to a normal terminal.
Reproduction is possible.

Embodiment 2 Embodiment 2 of the present invention relates to an ISDN subaddress editing function of a transmitting terminal when storing either or both of a calling number and a message in an ISDN subaddress area. It relates to the ISDN subaddress analysis function at the terminal on the receiving side.

Here, FIG. 4 to FIG.
FIG. 4 is a block diagram of an ISDN terminal device on the transmitting side according to the second embodiment. FIG.
It is the flowchart which showed the edit processing of SDN sub address. FIG. 6 shows an ISD on the receiving side according to the second embodiment.
It is a block diagram of N terminal device. 7 to 9 are flowcharts showing the ISDN sub-address analysis processing in the receiving terminal. FIG. 10 shows the IS at the receiving terminal.

The ISDN terminal on the transmitting side in FIG.
Network interface circuit 402 connected to line 401
, A sub-address editing unit 403 for editing a calling number or a message stored in a sub-address of a transmission signal, a message input unit 405 for inputting a message to be stored in the sub-address, and storing a message input from the message input unit 405. Storage means 404 for performing
There is provided a calling number storage means 408 for storing the calling number in the sub-address of the transmission signal, and these are mutually connected via a bus 407 and the operation is controlled by the main control unit 406. The sub address editing means 403
The ISDN sub-address is edited according to the flowchart shown in FIG.

Referring to the flowchart of FIG. 5, the subaddress editing means 403 stores a message coded by a combination of a character code and a numeric code after storing a calling number in an ISDN subaddress. This message is stored in the storage unit 404 after the message input from the message input unit 405 is converted into the IA5 character code. Then, the storage means 40
4 is stored in the sub-address editing means 40.
3 is stored in the ISDN subaddress.

Here, the editing process of the ISDN subaddress executed by the subaddress editing means 403 will be described with reference to the flowchart shown in FIG. To edit the ISDN subaddress, first, as shown in step 501, the calling number is stored in the ISDN subaddress. This process is performed by storing the information in the ISDN sub-address by the calling number storage unit 408 under the control of the main control unit 406 when calling the terminal. Next, the main control unit 406 determines in step 502 that the storage unit 404
Check whether a message to be transmitted is stored in the. If the message to be transmitted is not stored, the process proceeds to step 507 (NO in step 502), and the ISDN subaddress editing ends. If a message to be transmitted is stored (step 50)
If YES in step 2), the process proceeds to step 503. here,
First one of the messages stored in storage means 404
Compare the code with the IA5 character code. As a result, if the first code of the message to be transmitted is a numeric code (YES in step 503),
Proceed to step 504. In step 504, an identification code is inserted before the first code of the message to be transmitted. This identification code is a code for distinguishing a numeric code as a message from a numeric code as a calling number input in step 501, and includes STX and EOT.
And the like. After inserting the identification code in step 504, step 505
Then, the message stored in the storage unit 404 is stored in the ISDN subaddress. Therefore, when the first code to be transmitted is a numeric code, an identification code is inserted after the last code of the numeric code representing the calling number, and a message to be transmitted is inserted after this identification code. Procedure. Thus, when the terminal on the receiving side detects the identification code, it is possible to determine all codes below the identification code as a message.
When the process of step 505 is completed, the process proceeds to step 507, where the editing process is completed.

On the other hand, if the first code of the message to be transmitted is a character code (N in step 503)
In the case of O), the process proceeds to step 506. In step 506, a message to be transmitted next to the last code of the numerical code representing the calling number is inserted. As a result, when the terminal on the receiving side detects the first character code next to the numeric code representing the calling number, it is possible to determine all codes after the character code as a message. In step 506, when the storage of the message in the ISDN subaddress area is completed, the process proceeds to step 507, where
The editing of the DN subaddress ends. As described above, according to the present invention, when storing the calling party number and the message in the ISDN subaddress, as in the related art, the STX and the ETX are used.
Since it is not necessary to use both control codes of OT, I
The SDN sub-address area can be used effectively. Also, the terminal on the receiving side does not need to compare all codes included in the ISDN subaddress with the IA5 character code to identify the calling number and the message, so that the terminal can be configured easily.

Next, FIG. 6 shows a block diagram of the terminal on the receiving side. The terminal includes a network interface circuit 602 connected to the ISDN line 601, a sub-address identifying means 603 for identifying a calling number or message stored in a sub-address of an incoming signal, and a calling number or A display unit 604 for displaying a message, and a speaker 605 for performing a notification process for notifying a recipient that the calling number or the message has been received.
And a storage means 606 for separately storing the calling number or message stored in the sub-address of the incoming signal. These are connected to each other via a bus 608 and are controlled by the main control unit 607. Operation is controlled. The sub address identification means 603 performs an ISDN sub address analysis process as shown in the flowchart of FIG.

Here, the analysis process of the ISDN subaddress will be described with reference to the flowchart shown in FIG. FIG.
In the flowchart shown in FIG. 7, not only a case where a signal including a calling number or a message is received in the ISDN sub-address area but also a case where a signal transmitted without any information being carried in the ISDN sub-address area is received is considered.

In step 701, the receiving terminal confirms whether or not an ISDN address has been received. If it has not been received (NO in step 701), the flow advances to step 706 to terminate the analysis. ISD
If the N sub address has been received (YES in step 701), the flow advances to step 702 to check whether or not the ISDN sub address area is used. here,
The reason for checking whether or not the ISDN sub-address area is used is that the ISDN sub-address area is not a telecommunications carrier and can be used freely by the user, and thus the area may not be used. Therefore, when it is determined in step 702 that the ISDN sub-address area is not used (N in step 702
In the case of O), the process proceeds to step 706, and the analysis ends.
On the other hand, if it is determined that the ISDN sub-address area is used (YES in step 702), the flow advances to step 703 to check whether the stored information is only the calling number. If there is only the calling number (YES in step 703), the process proceeds to step 705, where the calling number is displayed on the display unit 604, and the calling number is stored in the storage unit 606. On the other hand, if a message is stored in addition to the calling number (NO in step 703), the process proceeds to step 704, where the message is displayed on the display unit 604, and the message is stored in the storage unit 606. Then, after proceeding to step 705, the calling number is displayed on the display unit 604, and the calling number is stored in the storage means 606. In this case, the calling number and the message are separately stored in different areas in the storage unit 606. Therefore, when it is desired to read out the calling number or the message stored in the storage unit 606, the calling number and the message can be easily distinguished and read out by operating a button not shown in FIG. 6 and displayed on the display unit 604. it can. Further, it is not necessary to newly provide storage means for storing the calling number and the message, respectively, and the present invention can be realized with a simple configuration. When the message is only a character code, the calling number is distinguished from the message solely by comparing the IA5 character code with the numeric code and the character code. Therefore, the terminal can be easily configured from this point. Furthermore, according to the above configuration, it is not necessary to newly provide a complicated device, the calling number and the message can be easily identified, and the convenience of the terminal can be improved.

Finally, when the processing in step 705 is completed, the process proceeds to step 706, and the analysis is completed.

Here, the processing in step 703 will be described in more detail. FIG. 8 shows the procedure of the process of identifying the calling number stored in the ISDN subaddress and the message in step 703 when the message is described only with the character code. FIG. 9 shows the procedure of the process of identifying the calling number stored in the ISDN subaddress and the message in step 703 when the message is described by a combination of a character code and a numeric code. FIG. 10 shows a specific example of a process of identifying a calling number and a message in an ISDN subaddress area in a receiving terminal.

First, referring to FIG. 8, in step 703 when the message is only a character code,
A procedure for identifying a calling number stored in the ISDN subaddress and a message will be described. In step 801, the first one stored in the ISDN subaddress is
The code is extracted, and it is determined whether the code is a numeric code or a character code. If it is a character code (NO in step 801), all codes stored in the ISDN subaddress are determined as messages (step 805), and the process proceeds to step 704 (step 80).
6).

Next, with reference to FIG. 9, a description will be given of the procedure of the process for identifying the calling number stored in the ISDN subaddress and the message in step 703 when the message is a combination of a character code and a numeric code. In step 901, the first code stored in the ISDN subaddress is extracted, and it is determined whether or not the code is an identification code. If it is an identification code (YES in step 901), the second and subsequent codes are determined as messages (step 905), and the process proceeds to step 704 (step 906). On the other hand, if the first code is not an identification code (NO in step 901)
), The process proceeds to step 902, and it is determined whether or not an identification code exists after the second code. If it is determined that an identification code is present in the N-th code (YES in step 902), the first to N-1st codes are determined as calling numbers, and the N + 1-th and subsequent codes are determined as messages. (Step 903). Then, the process proceeds to step 704 (step 904). Also,
If the identification code does not exist in the second and subsequent codes in step 902 (N in step 902).
If O, the process proceeds to step 705 (step 90).
7).

Next, with reference to FIG. 10, a specific example of the process of identifying the calling number of the ISDN sub-address area and the message in the receiving terminal will be described.

FIG. 10 (a) shows an IS in which a calling number is described only by a numeric code and a message is described only by a character code.
It shows a specific example of a procedure for analyzing a DN subaddress. The receiving-side terminal analyzes the codes in order from the top, and when detecting a code 1001 other than a number, determines the code below the code as a message.

FIG. 10 (b) shows a specific example of an ISDN subaddress analysis procedure in which the calling number is described only with a numeric code and the message is described with a combination of a character code and a numeric code. The terminal on the receiving side analyzes the codes sequentially from the top, and when detecting the identification code 1002, determines the code below the code as a message.

FIG. 10C shows a specific example of an analysis procedure in a case where the calling number is omitted and the message is stored only in the character code in the ISDN sub-address area. In this case, the terminal on the receiving side analyzes the codes in order from the top, and when the character code 1003 is detected, determines the code below the code as a message.

FIG. 10 (d) omits the calling number and uses the combination of a numeric code and a character code to convert the message to ISDN.
FIG. 9 shows a specific example of an analysis procedure when the data is stored in a sub-address area. In this case, the terminal on the receiving side analyzes the codes in order from the top, and when the identification code 1004 is detected, the code below the code is determined to be a message.

As described above, according to the present invention, only a number code that is continuous from the beginning is treated as a calling number, and it can be determined as a message when a character code or identification code other than a number code is detected. Therefore, the calling number and the message can be efficiently identified with a simple configuration as compared with the related art, and more information can be transmitted and received.

[0045]

According to the ISDN terminal of the present invention, a receiving means for receiving an ISDN subaddress storing either a calling number represented by a numeric code or a message represented by a character code; If the first one code of the sub-address is a numeric code, it is determined that the calling number is stored. If the first one code is a character code, it is determined that the message is stored. When the identification means and the identification means determine that the calling number is stored in the received ISDN subaddress, the first notification processing is performed, and when it is determined that the message is stored, Since there is provided a notification means for performing the second notification processing, one or both of the calling number and the message are transmitted and received in the ISDN sub-address area. You can, also, can inform as to identify efficient calling number and message with a simple configuration, the recipient by different notification process incoming of the calling number and message. Further, by displaying the received message and the calling number on the display means, the user can easily determine whether or not the communication requires a response.

Further, by not performing the notification processing by the notification means in accordance with the time zone, for example, when it is not possible to answer the telephone during a meeting or the like, the message can be received without disturbing the surroundings.

Further, according to the present invention, since the calling number and the message can be separately stored in the storage means provided in the terminal, the received calling number and the message can be read separately. Therefore, it is not necessary to newly provide storage means for storing the calling number and the message, respectively, and the present invention can be realized with a simple configuration. Further, since the received message and the calling number are respectively stored, accumulation and reproduction of information when the user is absent can be easily realized.

Claims (6)

[Claims] 1. An ISD receiving an ISDN subaddress.
N terminal device: a receiving means for receiving an ISDN subaddress for storing either a calling number represented by a numeric code or a message represented by a character code; and the first code of the received ISDN subaddress is a numeric code If the first code is a character code, it is determined that the calling number is stored, and if the first code is a character code, it is determined that the message is stored. When it is determined that the calling number is stored in the received ISDN subaddress, a first notification process is performed, and when it is determined that a message is stored, a notification device that performs a second notification process is performed. An ISDN terminal device comprising: 2. An ISD for receiving an ISDN subaddress.
N terminal device: a receiving means for receiving an ISDN sub-address for storing a calling number represented by a numeric code, and / or a message represented by a combination of a character code and a numeric code; Identification means for identifying the stored calling number and message; and notification means for performing notification processing according to the identification result of the identification means, wherein the identification means detects a code stored in the ISDN sub-address, If a character code is detected after the number code representing the calling number, it is determined that the code following the character code is a code representing the message. If an identification code is detected, the code following the identification code is a code representing the message. If the first code stored in the ISDN subaddress is a character code, it is determined that the code after the character code is a code representing a message, and the first code stored in the subaddress is If it is an identification code, it is determined that the code following the identification code is a code representing a message,
Identifying the calling number and the message stored in the SDN subaddress, the notifying means, the ISDN received by the identifying means
When it is determined that the message is not stored in the sub-address, the first notification processing is performed. When it is determined that the message is stored in the received ISDN sub-address, the second notification processing is performed. Characteristic ISD
