Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a control method for controlling a terminal connected to an ISDN (ISDN terminal) via a line (prior art). Q of CCITT Recommendation
, 931 defines the call control means. According to the recommendation, the information for instructing the destination of a call includes the destination address for specifying the subscriber, the destination subaddress information element for specifying multiple terminals connected to the subscriber line, and the calling side terminal. It is possible to send a call setup message (SETUP) including a caller subaddress information element for conveying the call.

Originally, the layer sub-address is prepared so that a call can be received only when a matching destination sub-address is registered by registering an address determined for each terminal.

Furthermore, as a method of using the sub-address, it is known that the sub-address is used as a user ID as a password.

(Problems to be Solved by the Invention) However, conventionally, subaddresses have been used only to determine whether or not a call can be received, and the range of use of subaddresses has been limited.

The present invention has been made with this point in mind, and it is an object of the present invention to provide a terminal control method that can improve the controllability and operability of an ISDN terminal by effectively utilizing subaddresses.

(Means and Effects for Solving the Problems) To achieve the above object, the present invention provides a method for controlling a terminal accommodated in an ISDN line, in which a terminal command corresponding to a predetermined subaddress value in a call setup message is pre-programmed. The method corresponds to the value of the subaddress in the call setting message by memorizing the subaddress, detecting the subaddress in the received call setting message, and executing processing according to the stored terminal command according to the value of the detected subaddress. In this configuration, preset processing is executed.

Further, when it is determined that call connection is not necessary based on the detected subaddress value, a paging message is sent to the ISDN line as a signal for confirming the operation of the terminal, and when control is completed without performing call connection, A paging message is sent as an operation confirmation signal.

(Example) Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the configuration of an answering machine which is an embodiment of a terminal to which the control method of the present invention is applied.
A DN line 1 is connected to a network control unit (hereinafter referred to as rNcUJ) 2. NCU2 is 1, 431°Q, 921. Q. Layer 1 of 931~

The NCU 2 includes a voice response means (for example, configured using a semiconductor memory) for responding to the other party by voice after responding by the control unit 6, and a voice recording means 4 for recording the other party's message.
are connected via analog signal lines 12 and 13.

In addition, the NCU2 transmitting/receiving circuit (analog signal line 12.13
) is connected to a handset 5 for making calls.

The voice response means 3 and the voice recording means 4 are each connected to a control section 6 via control lines 10.11, and their operations are controlled by the control section 6. The control unit 6 includes
Furthermore, a key manual means 7 having an input button for dialing when making a call or controlling the terminal, an order number storage means 8, and an absent message counter 14 for counting the number of recorded messages of the other party are connected. There is. The order number storage means 8 stores predetermined processing to be executed upon command from the control unit 6 (for example, sending a voicemail message, which will be described later),
In order to make the NCU 2 correspond to the received sub-address or originating sub-address number, the sub-address number (sub-address value) and the predetermined process corresponding to that number are stored, and this storage content is stored in the key manual means. 7
Set by.

2(i!I) is a flowchart showing the operation of the terminal in FIG. 031) arrives from the network, the NCU 2 receives the message and transfers it to the control unit 6.Control unit 6
Checks whether the call setting message contains a called subaddress or not, and if there is no called subaddress, the process proceeds to steps 38 to 39.

In step 39, it is checked whether or not the answering mode is set, and if the answering mode is set, a response is sent (step 40), and after sending a response message (
Step 41), enters the recording state (Steps 42 and 43)
). Thereafter, the call is disconnected when disconnection from the calling party is detected or after a certain period of time has elapsed. If the called number is available after disconnection, it is desirable to record the called number along with information on the time of the call and the day of the week. This recording of the called number can be performed by providing an audio means for vocalizing the called number.

If it is not in the answering mode in step 39, it sends an alert message (ALERT) to the line (step 45) and sounds an incoming call (step 46).
The device is placed in an off-hook waiting state (step 47).

When there is a called subaddress in the call setup message,
Step 21.27.3 according to the number of the destination subaddress
Go to either 0 or 44.

When the called sub-address number is "1", in this embodiment, the response process to the answering machine state is performed, so the process proceeds from step 21 to step 22, and the count value of the answering message counter 14 is checked to determine whether or not there is an answering message. Determine. If there is a message on the answering machine, it responds (step 23), activates the voice recording means 4 to reproduce the message, and sends it out to the line (step 24). If there is no answering message, it is determined that there is no need to connect the line and a call message (Q) is sent.

931) to the line (step 25), and waits for disconnection (step 26). As a result, the caller can hear the ring tone and the telephone does not respond, thereby letting the caller know that there is no voicemail message even if the caller does not connect the line.

When the called sub-address number is "2", in this embodiment, the setting process for answering answering mode is performed, so the process proceeds from step 27 to step 28, setting the answering answering mode, and sending out a ring tone ( Step 29), proceed to step 26 above.

Furthermore, when the called subaddress number is "3", in this embodiment, the answering mode is canceled, so the process proceeds from step 30 to step 31, where the answering mode is canceled and a ring tone is sent out. (Step 32), the process proceeds to step 26.

When the destination subaddress number is r:lJ or r3J, "
1), by sending a paging message to the line, the caller, that is, the person who instructs this terminal (answering machine) to process the process via the line, can receive a message even if the line is not connected. , you can confirm that the instructed process has been executed.

When the destination subaddress is "43", in this example, 3
Since the process is to send the th response message, the process proceeds from step 33 to step 34, and after responding (
Step 34), change the response message to the third response message (Step 35), send the third response message to the line (Step 36), and wait for disconnection (Step 37).

Further, in this embodiment, the called sub-address is used as a 4-digit password, and when the called sub-address is "1234", the incoming call will ring even if the answering mode is set, so step 44 The process then proceeds to step 45.

By using the destination sub-address as described above, it becomes possible to control the other party's terminal (the M default terminal) before the line is connected, and operations after the line is connected can be performed quickly. Furthermore, since it can be used as a different instruction code, terminal control becomes easy, and if a line connection is not required, control can be completed with just a dial, providing good operability. In addition, by returning only the ring tone to the caller (the person attempting to control the called terminal), the caller can quickly confirm control or confirm the response of the terminal even if the line is not connected. Therefore, the operations instructed via the line will be executed reliably, and you can use it with peace of mind. Furthermore, by using the subaddress, it becomes possible to control the other party's terminal even from a terminal that cannot perform tone dialing.

In addition, in the embodiment described above, the destination sub-address is used, but the originating sub-address or both the destination sub-address and the originating sub-address may be used. Furthermore, in addition to the above-described process, for example, the ringing sound may be changed depending on the sub-address number (particularly by using it as a password), so that the caller can be identified from the ringing sound. Unlike the known technology that changes the ringing tone depending on the calling number, this is more valuable in that it can be used even from ISDN Public 11.

Naturally, such a function is not limited to the above-mentioned answering machine, but can also be provided in a regular telephone.

Further, in the above embodiment, an example was shown in which a ringing tone is sent as a confirmation signal, but the present invention is not limited to this, and for example, a reason display information element in a release message (DISC) may be used as a confirmation signal.

FIG. 3 shows a telecontrol system (remote control terminal) which is another embodiment of the terminal to which the control method of the present invention is applied.
FIG. 2 is a block diagram showing the configuration of FIG. 1, in which components having the same functions as those in FIG. Third
In the figure, a terminal 55 constituting the telecontrol system is multi-point connected to another terminal 54. The control unit 6 of the terminal 55 is connected to a control means 51 for controlling external equipment, and the control means 51 is connected to external equipment (for example, [52, bath 53, etc.]).

FIG. 4 is a flowchart showing the operation of the terminal 55, and step 6o shows an idle state, that is, a state of waiting for an incoming call. Upon receiving the call setup message, the NCU 2
The message is sent to the control unit 6 (step 61), and the control unit 6 determines whether or not there is a called subaddress in the call setting message (step 62). If there is no called sub-address, the process shifts to an idle state (step 73); if there is a called sub-address, the called sub-address is compared with the called sub-address previously stored in the order number storage means 8 to determine whether the call is arriving at the own terminal. (Step 63). In this embodiment, when the first digit of the called subaddress is "7", it is determined that the call has arrived at the own terminal, and step 6
On the other hand, if the first digit is other than r7J, the process moves to an idle state (step 73). In step 64, check the second and subsequent digits of the destination subaddress, and if the second digit is rlJ, go to step 65, and if it is "2", go to step 7.
Go to 0. In this embodiment, when the second digit is rlJ, the key 52 is controlled, and when the third digit is [1] in step 65, the lock is unlocked (step 66), and the key 52 is unlocked (step 66).
If it is other than lJ, the door is locked (step 68). Thereafter, a paging message is sent to the line as a confirmation signal (Step 67), and the state transitions to a standby state for disconnection (Step 6).
9) In step 67, the voice generating means 3 may send out a confirmation message instead of the calling message. By sending a paging message or a confirmation message, the caller can confirm the instructed operation.

In step 64, when the second digit of the destination subaddress is [2J], the process advances to step 70, and the bath 53 is controlled. In step 70, the third to seventh digits are r21.
234J or not, and if it is r21234J, start boiling the bathtub (step 71), and proceed to step 67.

On the other hand, if the 3rd to 7th digits are not "21234", the system shifts to an idle state (step 72), and at this time a release message may be sent.

In this embodiment as well, the originating subaddress or both the destination subaddress and the originating subaddress may be used. Also,
External devices are not limited to keys or bathrooms, but also VT.
Various things such as R can be controlled. At this time,
It is desirable that a response signal be sent back from the controlled device. Furthermore, the external device control signal may be transmitted via a home bus, power line, or the like.

(Effects of the Invention) As detailed above, the present invention provides the following effects.

According to the terminal control method of claim 1, processing is executed based on the terminal command set corresponding to the value of the subaddress in the call setup message, so that the called terminal (controlled terminal) is connected to the line. The terminal can be controlled before connection. As a result, not only can processing after line connection be performed quickly, but when line connection is not required, control can be completed simply by dialing the calling terminal (controlling terminal), improving operability. be able to. Further, even if the calling terminal does not have a tone dial function, the receiving terminal can be controlled.

Furthermore, even if the calling terminal is a public telephone, it is possible to add a function that allows the calling party to be identified.

According to the terminal control method of claim 2, when a call connection is not required, a paging message is sent as an operation confirmation signal, so the caller can quickly and quickly confirm the operation even if the line is not connected. Reliable terminal control becomes possible.
