[0001] 1. Field of the Invention [0002] The present invention relates to a communication apparatus and a communication method for ISDN (Integrated Services Digital Network) for utilizing ISDN user information.

[0002]

2. Description of the Related Art User information (UUI) is based on ISD.
It is transmitted and received in N layer 3 processing. That is, the exchange has an I interface (digital subscriber line interface), and when this exchange transmits and receives information using ISDN, it is possible to transmit and receive user user information through the D channel (signal channel) of the I interface. . The message transmitted / received by the user information is displayed on a display device of a terminal accommodated in an ISDN compatible exchange or a display of a digital telephone terminal. According to the user information, a relatively small amount of messages, such as character information, are transmitted and received via the terminal.

[0003] This technology using user information includes:

As shown in FIG. 2, the table 1 includes storage areas 11 ₁ to 11 _n , and each storage area has storage area portions A and B. The memory 14 stores the caller number in the storage area portion A in advance. For example, in the storage area 11 ₁ in the storage area part A, caller ID "0123
456789 ”is stored. Also, the memory 14
A message corresponding to the caller number of storage area portion A is stored in storage area portion B of each storage area in advance. For example, in the storage area 11 ₁ in the storage area part B, and stores the message "portable 9876543210 two Ren Raku Kudasai" corresponding to the caller number "0123456789".

As described above, the memory 14 stores a message corresponding to a specific sender.

[0027] Table 2, as shown in FIG. 3, a storage area 12 ₁ to the storage area 12 _n. The memory 14 stores a message in each storage area in advance. For example, in the storage area 12 _1, and stores the message "I'm home Telephone Nidera Rema Sen".

As described above, the memory 14 stores messages corresponding to unspecified callers.

Analog line interface circuit 16
Monitors the telephone 210, which is an analog telephone terminal.
At this time, the analog line interface circuit 16
After detecting off-hook by the handset 211 of the telephone 210 and detecting a special number operation indicating the setting of the answering machine mode by the push button 212, the control circuit 13 is notified of the special number operation of the answering machine mode.

Analog line interface circuit 16
Detects an off-hook operation by the handset 211 of the telephone set 210, and then detects a special number operation for selecting a message in the table 2, and notifies the control circuit 13 of the special number operation for message selection. At the same time, the analog line interface circuit 16 sends the special number input at this time to the control circuit 13.

The control circuit 13 performs overall control on the ISDN exchange 1. Further, the control circuit 13 performs the following control regarding the answering machine mode. That is, the control circuit 13
Receives the signal indicating the special number operation for setting the answering machine mode from the analog line interface circuit 16, and controls the answering machine mode. Control circuit 13
Receives the caller number from the D-channel control circuit 12 in the answering machine mode, and compares the caller number stored in the table 1 of the memory 14 with the received caller number. As a result of this comparison, when the same caller number is detected in table 1, control circuit 13 reads a message corresponding to this caller number from table 1 in memory 14.

Thereafter, the control circuit 13 generates user information using the read message. The user information generated by the control circuit 13 is 128 octets of data as shown in FIG. In this user information, the first to third three-octet basic part 111 and the fourth to seventh four-octet command part 112 are followed by eighth to 128th octets. A message section 113 for insertion follows.

The control circuit 13 inserts the message read from the memory 14 into the message section 113 of the user user information to generate the user user information. Then, the control circuit 13 sends the generated user information to the D-channel control circuit 12.

When the same number is not detected in the memory 14 as a result of the comparison of the caller number, the control circuit 13 reads out a preset message from the table 2 from the memory 14. Thereafter, the control circuit 13 generates user information using the read message. Then, the control circuit 13 sends the generated user information to the D-channel control circuit 12.

The control circuit 13 performs such control on the user information.

Next, the operation of this embodiment will be described.

The user inputs a special number by operating the telephone 210 in order to respond to a call from a specific caller when he is away. Further, the user operates the telephone 210 to input a special number and set a message to be transmitted in order to respond to a call from an unspecified caller when the user is away. The analog line interface circuit 16 is connected to the handset 2 of the telephone 210.
Push button 2 after detecting off-hook by 11
When the setting of the answering machine mode and the special number operation for selecting the message are detected, these settings and numbers are sent to the control circuit 13. When receiving the signal indicating the special number operation and the message selection number, the control circuit 13 starts the control of the answering machine mode.

In this state, if there is an incoming call from the digital line 101, the basic interface circuit 11
Connects the D channel of the digital line 101 to the D channel control circuit 12. The D channel control circuit 12 is configured as shown in FIG.
As shown in (1), the caller number is read from the call setup message received from the D channel, and the caller number is sent to the control circuit 13.

The control circuit 13 includes a D-channel control circuit 12
When the caller ID is received from the
Is compared with the received caller number. Then, if the same caller number is in table 1, control circuit 13 reads out the message corresponding to this caller number. Thereafter, the control circuit 13 generates user information using the read message. The control circuit 13 sends the generated user information to the D-channel control circuit 12.

When the D-channel control circuit 12 receives the user information, it transfers this information to the D-channel of the basic interface circuit 11 by a call setting acceptance message (FIG. 5). This causes a message for the particular caller to be returned over the D channel. Upon receiving the message, a message indicating disconnection is sent from the partner terminal.

If the caller ID received by the incoming call is not in Table 1, the control circuit 13
The message corresponding to the number set in
From the table 2 of FIG. After this, the control circuit 13
Using the read message, user information is generated. The control circuit 13 sends the generated user information to the D-channel control circuit 12. As a result, a message for an unspecified sender is returned by the D channel.

Thus, according to this embodiment,
It is possible to set the answering machine mode by operating the telephone 210 which is an analog telephone terminal. Further, by operating the telephone 210, it is possible to separately transmit a message for a specific caller and a message for an unspecified caller.
