Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an improvement in a communication terminal device connected to a digital subscriber line premises bus.

(Prior Art) In order to cope with the increasingly sophisticated and diversifying data communication demands, there is a digital life data exchange network.

This digital data exchange network is a service of the network part, and indicates interface conditions that are connection conditions to the network, accommodates terminals that meet these conditions, and provides exchange services. Therefore, subscribers can connect desired terminal equipment and use it for communication as long as it meets the interface conditions.

In such a digital switching network, digital subscriber lines are connected to a local bus, and terminal equipment is connected to the local bus for use. Up to eight communication terminal devices can be connected via the in-house bus per digital subscriber line. A telephone number, ie, a destination address, is assigned to a local bus, and each terminal is identified by a subaddress. This subaddress can be set up to 40 digits. In addition, since this sub-address is set for the terminal device, it remains unchanged no matter which of the eight sockets on the home bus the terminal device is connected to, and it is possible to receive calls to that specific terminal device using a sub-address unique to the terminal device. can. Therefore, the number of terminal devices that can be connected to the home bus at the same time is up to eight, but it is also possible to use a large number of terminal devices, such as eight or more terminal devices, by replacing them.

Therefore, when a large number of terminal devices are used by replacing them, unless the subaddresses are numbered in a way that is as easy to understand as possible, it will be extremely difficult for the user to use the subaddresses. For example, if each terminal device is numbered in descending order, the numbering is easy, but there is no regularity, and the user will have trouble remembering which number corresponds to which terminal device.

On the other hand, the terminal device owned by person A has a sub-address in the 100s, the terminal device owned by person B has a sub-address in the 200s, and so on. It will be easier to remember, but you will still not be able to fully grasp it.

(Problems to be Solved by the Invention) As described above, in a digital switching network, digital subscriber lines are connected to a home bus, and up to eight terminal devices can be connected to this home bus per subscriber line. It can be used. Further, a telephone number, that is, a destination address is assigned to a local bus, and each terminal is identified by a subaddress. This subaddress can be set up to 40 digits. In addition, since this sub-address is set for the terminal device, it remains unchanged no matter which of the eight sockets on the home bus the terminal device is connected to, and it is possible to make a call to that specific terminal device using the sub-address unique to the terminal device. Can be done. Therefore, although up to eight terminal devices can be connected to the home bus at the same time, it is also possible to replace and use a large number of terminal devices, such as eight or more terminal devices.

Therefore, when a large number of terminal devices are used by replacing them, unless the subaddresses are numbered in a way that is as easy to understand as possible, it will be extremely difficult for the user to use the subaddresses. However, even if numbers are assigned systematically, if there are many terminal devices, the user cannot remember which number corresponds to which terminal device.

Therefore, when communicating, it is necessary to check what the subaddress is, which hinders smooth use.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a communication terminal device with good operability, which is easy for the user to understand and allows the user to easily enter a subaddress and communicate.

[Structure of the invention]

(Means for solving problems) In order to achieve the above object, the present invention is configured as follows.

That is, a specific address is assigned to the subscriber line home bus connected to the digital communication network, and the communication terminal devices to which sub-addresses are assigned for each communication terminal device are connected to the home bus, and when the communication terminal devices communicate with each other, A communication terminal device for a digital communication network that uses the above address and sub-address to establish a line connection with a party specified by these addresses includes an input means for inputting a character string, a character code for this character string, and a numeric code for converting the character code into a number. It is configured by providing code conversion means for encoding, and output means for receiving the numeric hood and outputting it as a sub-address of the other party, and each communication terminal device converts a character string into a character code as its sub-address, and converts the character string into a character code string. The configuration uses a numeric string obtained by converting the digits into numerical codes.

(Function) In such a configuration, the subscriber line home bus connected to the digital communication network is assigned a specific address, and the communication terminal equipment is assigned a specific sub-address for each communication terminal equipment. It is possible to communicate with a specific communication terminal device by connecting the communication terminal device to a home bus connected to the subscriber's line and inputting the above address and subaddress. In such a communication terminal device, a subaddress of the communication terminal device is assigned using a number string obtained by converting an easy-to-understand and meaningful character string into a character code, and further converting the character code string into a numeric code. When communicating, the other party's address and the above character string of the other party are inputted from the input means of the communication terminal device. Then, the code conversion means converts the input character string into a character code, and the output means outputs the character code string as a partner subaddress together with the partner address. This allows you to connect to the target party and communicate with them.

As described above, the present invention uses a numeric string obtained by converting a meaningful character string that is easy to understand, such as a user's name, into a character code and converting the character code string into a numeric code string for the sub-address of a communication terminal device. At the same time, the terminal device has the function of converting the input character string into a character code, converting the character code string into a numeric code string, and outputting it as a sub-address of the other party, so that the user of the communication terminal device can input the sub-address of the other party. If you enter the name of the other party in letters instead of numbers, it will be automatically converted into a numeric code for the subaddress and sent, allowing you to easily and easily communicate with the communication terminal device of the intended party. You will be able to do this. As a result, it is possible to provide a communication terminal device with good operability, which is easy for the user to understand and allows the user to input a sub-address easily for communication.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 is a block diagram showing the configuration of a device according to the present invention, in which 1 is a digital subscriber line in-home bus, 2 is a line interface, 3 is a codec, 4 is a handset,
5 is a control section, 6 is a display section, and 7 is an input section.

Digital subscriber line in-home bus 1 has 2 channels of 64K Bps B channel (mainly used as a voice communication line) and 18K Bps channel.
D channels (mainly used for network control signal transmission and data communication) are multiplexed.

The line interface 2 separates the B channel signal and the D channel signal and distributes the signals to the codec 3 and the control unit 5. The line interface 2 also multiplexes the B channel signal and the D channel signal and connects it to the digital subscriber line premises bus. 1
It has a function to send to.

The handset 4 receives audio signals via the codec 3 and performs voice transmission and reception.

The control unit 5 is a control center that controls each component of the terminal device, and is composed of hardware centered on, for example, a CPU. In addition, the control unit 5 converts a character string with a specific meaning into a character code as a sub-address in advance, and sets the numeric string of this character code as a sub-address, so that when this sub-address arrives from the line, this communication terminal device Knowing that you are being called, connect to the other party's terminal so that it can communicate. The display section 6 is composed of a liquid crystal or an EL (electroluminescence) element, and displays input information, messages, or received information. The input section 7 is composed of dial keys and a keyboard for inputting characters. Further, when the control unit 5 receives a partner name input from the input unit 7, the controller 5 includes a partner name input means 51 which accepts this as a partner name, converts the received partner name into a character code,
Functional means such as code conversion means 52 for converting this code into a number string and subaddress sending means 53 for sending out this number string as a subaddress are added.

Among these, the partner name input means 51 has a function of accepting characters of the partner's name input from the keyboard of the input section 7 after inputting a young address by the input section 7, and the code conversion means 52 receives input from the keyboard of the input section 7. Converts the input character code to the numeric code of the subaddress. Specifically, in the case of English capital letters, the character code is 65 to 9 in decimal.
Since it is indicated by a 1-byte code of 0, the 1 of each character code
Convert the 0's digit and 1's digit into numeric codes. For example, rAJ has a character code of 65, so the numeric code 54 for 6 (36h in decimal or hexadecimal notation) and the numeric code 53 for 5 (35h in decimal or hexadecimal notation) Expressed in 2 bytes. Therefore, the other party's name is rYAMA.
In the case of DAJ, the character code is 89.85°77, 65.
It is 88.65. At this time, set the sub address to r89.8
5.77, 65.88.65J, numerical code r38
h, 39h, 38h, 35h, 37h
, 37h, 36h.

85h, 36h, Hh, 38h, 35
h Convert to J. The subaddress sending means 53 is a functional means for sending the subaddress numeric code thus obtained to the line through the D channel in the format shown in FIG.

In such a configuration, the digital subscriber line home bus 1 is multiplexed with a B channel, which is mainly used as a voice communication line, and a D channel, which is mainly used for transmission of network control signals and data communication. When the other party's communication terminal sends information in the format shown in FIG. 3, including the address and subaddress of the digital subscriber line, to the digital communication network, it is connected to the subscriber line premises bus 1 corresponding to the destination address, which is the call number. The communication terminal device connected to the subscriber line premises bus 1 separates the sent information into a B channel signal and a D channel signal via a line interface 2 and distributes the signals to a codec 3 and a control unit 5. .

The control unit 5 receives the sent information and checks whether the subaddress matches its own, and if it does, it determines that the communication is for itself and sends and receives the information, and the necessary information is displayed on the display unit 6. and output to other output devices. In addition, with voice communication, the user can communicate with the other party using the handset 4.

Next, the case where the communication terminal device calls the other party's communication terminal device will be explained. In this case, the input unit 7 is operated to input the recipient's destination address, and then the name of the recipient's terminal device is entered in text. The control unit 5 is provided with functional means such as a destination name input means 51, a code conversion means 52, and a sub-address sending means 53. Among these, the destination name input means 51 is used to input information from the keyboard after inputting the destination address. This is a function to import the characters of the name of the other party, and the character string of the other party's name entered by this function is imported. This taken-in character string is converted by code conversion means 52 into a numeric code of the subaddress. Specifically, the details are as follows; in the case of uppercase English letters, the character code is represented by a 1-byte code of 65 to 90 in decimal, so convert the tens and ones places of each character code into numerical codes. do.

For example, rAJ has a character code of 65, so the numerical code of 6 is 54 (36h in decimal or hexadecimal notation).
Numeric code 53 (35h in decimal and hexadecimal notation)
) is expressed in two bytes. Therefore, the other party's name is rYA.
In the case of MADAJ, the character code is 89°85, 77,
It is 85.88.65 and the numerical code is 38h.

39h, 36h, 35h, 37h, 3
7h, 36h, 35h.

36h, 38h, 38h, 35h.

The subaddress sending means 53 sends out the subaddress thus obtained through the D channel in the format shown in FIG. Actually, the line interface 2 multiplexes the B channel signal and the D channel signal and sends it to the digital subscriber line premises bus 1.

FIG. 2 is a flowchart showing the operation of the control section 5.

When the characters of the other party's name are input by operating the input section 7 (
In step stl), character capture is repeated until a delimiter such as a carriage return is encountered (step st2). When the delimiter comes and the input of the other party's name is completed, each character is converted into a numeric code (step st
l).

The subaddress information element shown in FIG. 3 is created using the converted numerical code (step sL4) and sent to the line (step st5).

FIG. 3 shows the format of control signals exchanged with the network through the D channel. Octet 1 stores a protocol identifier, octet 2 stores call number length information, and octet 3 stores call number information. Octet 4 stores the message type.

For example, an outgoing call sends out a "call setup" message. In octets 5 and below, parameters necessary for each message, that is, a group of information elements are arranged. The young subaddress is one of this information element. When the destination subaddress identifier is placed in octet n, each numerical code of the subaddress is stored in octet n+3 and below.

Then, it is arranged into such a format and sent to and received from the network through the D channel.

As explained above, in the present invention, the sub-address of a communication terminal device is converted into a character string with a meaningful character string that is easy to understand, such as the user's name, and then the character code string is converted into a numerical code, using a numerical string obtained. In addition to assigning a character string, the terminal device is equipped with the function of converting the input string into a character code, converting the character code string into a numerical code, and outputting it as the subaddress of the other party, so that the user of the communication terminal device can input the subaddress of the other party. If you enter the other party's name in letters instead of numbers, it will be automatically converted to the numeric code of the subaddress and sent, making it easy and
It becomes possible to easily communicate with the target communication terminal device.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with appropriate modifications within the scope without changing the gist.
