BACKGROUND OF THE INVENTION The present invention relates to ISDN (Integrated Services Digital Network).
k), and a method of operating the terminal.

[0002]

2. Description of the Related Art ISDN is capable of high-quality communication such as resistance to noise and crosstalk, has a strong affinity with a computer, is easy to perform communication processing, and can realize high-speed digital communication economically. Since it has the characteristics of, it can be used for communication of various data including image data as well as voice. ISDN also provides rich signals between users and the network.
Alternatively, it can be transmitted between users, and the convenience of communication can be greatly improved.

By making use of the latter feature, it is possible to confirm the possibility of communication and to add services such as call forwarding and call forwarding during communication prior to the start of communication.

[0004]

Taking call forwarding among the above-mentioned supplementary services as an example, this is because the callee side of this terminal is set by setting the telephone number of the forwarding destination in advance in this terminal. When a call is set up from the terminal, the call is transferred to the transfer destination terminal set in advance. In the past, call forwarding could only be set on the terminal itself. There are times when I want to transfer to a terminal installed in the new place because my own place has changed, and conventional terminals could not handle such a request.

The present invention provides a new ISDN terminal capable of giving an operation command including a call transfer setting from the first terminal to the second terminal.

[0006]

The present invention provides the first terminal for giving an operation command to the second terminal, the first terminal being the second terminal. Means for setting a command relating to the operation to be executed by the second terminal when a call is given to the second terminal, and a communication message including the set command, a call-in terminal for the second terminal. As a result, a means for transmitting to the ISDN switching network is provided.

The operating method of the first terminal according to the present invention sets and sets a command regarding an operation to be executed by the second terminal when a call is given to the second terminal. The communication message including the command is sent to the ISDN switching network with the second terminal as the called terminal.

The present invention also provides the second terminal, which receives a first call from the first terminal provided through the ISDN switching network. In response, means for determining whether or not the first call includes a command regarding an operation to be executed when the second call is given, and the command regarding the above operation is added to the first call. When included, if the command is set in the storage means, and if the command is set in the storage means when the second call is given, the operation according to the command is performed. It has the means to execute.

The operation method of the second terminal according to the present invention is such that, in response to the first call given from the first terminal through the ISDN switching network, the first call is transmitted to the first call. It is determined whether or not a command related to the operation to be executed is included when the second call is given, and if the command related to the above operation is included in the first call, the command is stored in the storage means. If the command is set in the storage means when the second call is given, the operation according to the command is executed.

The command related to the above operation includes cancellation of the command set previously.

In one embodiment of the present invention, the command related to the above operation is an incoming call transfer command including the identification code (telephone number, address, etc.) of the transfer destination terminal. However, the present invention is not limited to the call transfer instruction. For example, as disclosed in the patent application “ISDN terminal device, its operating method and ISDN system” (reference number 91018) by the same applicant and the same agent, the transfer destination terminal in the call transfer process or the communication transfer process It goes without saying that the present invention also includes setting of an operation command for notifying the calling side terminal of the identification information of the terminal and the identification information of the two terminals in the call in the three-way call processing.

[0012]

In the first terminal, an operation command for the second terminal is input, and the operation command is input to the second terminal.
It is transmitted via the SDN switching network.

When the operation command from the first terminal is received via the ISDN switching network, the second terminal sets the operation command in the storage means. After this, when call setting is performed from the third terminal (which may be the first terminal), the second terminal performs an operation according to the set operation command.

[0014]

As described above, according to the present invention, it is possible to set a predetermined operation command from not only the own terminal but also another terminal, so that the convenience of communication of the ISDN system can be utilized. The additional services provided can be further improved.

For example, regarding an operation command related to incoming call transfer, the user of the terminal device changes its location every time.
Since it is possible to instruct to transfer a call given to a terminal owned by oneself (for example, at home) to a terminal located at the user's place, the call transfer service can be used more effectively. become.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, the present invention is used to set a call transfer instruction.
An embodiment applied to the SDN terminal will be described in detail.

The incoming call transfer process in ISDN will be briefly described with reference to FIG.

The terminal C sends a call to the terminal A to the ISDN switching network, and in response to this, the switching network gives the call from the terminal C to the terminal A. When the call transfer is set to the terminal A, the terminal A requests the call transfer by designating the transfer destination terminal B to the switching network without answering the call. Since the switching network sends a call to the terminal device B in response to the incoming call transfer request, if the terminal device B responds to the call, the communication (call) between the terminal devices C and B becomes possible.

FIG. 2 shows an outline of the configuration of the ISDN terminal. This configuration is common to the terminals A, B and C described above.

The ISDN terminal has a CPU 10, and the CPU 10 controls the overall operation of the terminal.

The ISDN terminal is also provided with a transmission control unit 11, by which the terminal is connected to the ISDN switching network. The transmission controller 11 is controlled by the CPU 10.

The CPU 10 further includes an operation unit 13 including a handset 12 and its interface, dial keys, keys for setting and canceling call forwarding, information input from the operation unit 13, and other terminals. Liquid crystal display device 14 for displaying information transmitted from the computer and other information, CPU 10
Program memory 15 that stores the execution program of the program, main memory 16 that stores various data and various settings including the settings for incoming call forwarding, and user / user information that stores the incoming call forwarding setting information input from operation unit 13. Memory 17
Are connected. The user-user information memory 17 can also be realized by a part of the main memory 16. A user-user information area is provided in the primitive included in the communication message transmitted between the terminal and the ISDN switching network or between the terminals. The contents of the memory 17 are registered in this user / user information area.

In the system shown in FIG. 1, description will be made of a case where the terminal B sets the call transfer to the terminal A.

FIG. 3 shows a part of the processing procedure of the CPU 10 in the terminal B, which is related to the call transfer setting processing.

When the call transfer setting key provided on the operation unit 13 is pressed, the call transfer setting process is started (step 21). An appropriate key is used to select whether the call forwarding setting is set for the own terminal (that is, the terminal B) or the call forwarding setting is set for another terminal (for example, the terminal A or C) (step 22).

When setting the call forwarding of another terminal (here, the terminal A), the identification code of the terminal A (telephone number, etc.) and the identification code of the forwarding destination terminal in the call forwarding are input. To be done. By adding a call transfer control command to these input data, the call transfer setting information is edited and temporarily stored in the memory 17. After this, the edited call transfer setting information is registered in the user / user information area in the call setting communication message for the terminal A, and ISDN
It is sent to the switching network (steps 23 and 24).

The call transfer control commands include call transfer setting (including change; change of transfer destination telephone number) and call transfer cancellation. The types of these commands are also keyed.

However, the input of the call transfer setting, the own terminal,
Selection of another terminal, input of call transfer information, and the like are performed using the operation unit 13 while displaying a menu on the display device 14 and interactively viewing the screen of the display device 14 and responding to the screen display. It goes without saying that you can

Thereafter, the line is disconnected in response to the line disconnection communication message from the ISDN switching network (step 2).
5) The user / user information memory 17 is cleared (step 26), and the process ends.

In the call transfer of the own terminal, since the telephone number of the transfer destination (address of the transfer destination terminal) is input using the ten-key pad of the operation unit 13, the call is received in a predetermined area of the main memory 16. The fact that the transfer is set and the telephone number to which the call is transferred are stored (step 27).

When a function other than the call transfer setting is selected, the selected process is performed (step 2).
8).

FIG. 4 shows a processing procedure in the terminal A.

When the terminal A receives the call setup communication message from the ISDN switching network (step 31),
It is checked if there is any information in the user-user information area in the communication message (step
32).

If there is any information in the user / user information area, it is judged whether or not the information includes a control command for call transfer (step 33).

When the control command for the call transfer is included and the control command is the setting command (including the change) for the call transfer (step 34), the call transfer is performed in a predetermined area of the main memory 16. The setting and the transfer destination telephone number included in the call transfer setting information are stored (step 3).
Five). If the call transfer control command is to cancel the setting, the call transfer setting stored in a predetermined area of the main memory 16 is erased (step 36).

It is judged whether or not the terminal B should be notified that the processing for the call transfer control command is completed (step 37). Whether or not this notification should be sent can be set by the user in the terminal A in advance, or can be registered in the user / user information area in the communication message from the terminal B described above. Of course, this notification can be sent without fail. If it should be notified anyway,
The fact that the processing in accordance with the call transfer control command has been completed is set in the user / user information area, and this communication message is transmitted to terminal B via the switching network (step 3).
8). When terminal B receives this communication message,
The contents of the user-user information area will be displayed on the display device 14. After this, the line is disconnected (step 3
9).

User of received call setup communication message
If the information set in the user information area does not include the call transfer control command, other processing is performed according to the information in the user / user information area (step 40).

The user of the received call setup communication message
If there is no information in the user information area, it is determined that the call is for a normal call. In this case, it is checked whether or not the incoming call transfer is set in a predetermined area of the main memory 16 (step 41). If the call transfer is set, a call transfer request communication message including the telephone number of the transfer destination terminal is sent to the switching network (step 42). In response to this call transfer request, the switching network sends a call setting communication message to the transfer destination terminal. As a result, the terminal that has called the terminal A can communicate (call) with the transfer destination terminal.

When the call transfer is not set, the most general communication (call) processing is performed (step 4).
3).

The present invention can be applied not only to call transfer but also to call transfer. In addition to the call transfer setting, the present invention can be applied to the setting of notifying the calling side terminal device of the identification code (telephone number or name) of the transfer destination terminal device. Notification of such information can be extended to not only call transfer and call transfer but also notification of the identification code of the two parties in a three-way call.
