Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system having a packet switching function, and more particularly to a method of automatically setting a call to a terminating side device by designating a transfer destination list from a calling terminal.

[0002]

2. Description of the Related Art A conventional example will be described below with reference to FIG. FIG. 5 is a diagram showing a system configuration of a conventional example. FIG. 5 (A) shows the system configuration, and FIG. 5 (B) shows a call deflection function.

In FIG. 5A, 10 is a network having a packet switching function. Reference numeral 11 is a first terminating device on the data transmission side, and 11a is a display screen of the first terminating device 11. Reference numeral 14 is a first host computer (first host).

Further, 20 is a second host on the data receiving side, and 21 is a personal computer communication center on the data receiving side. Generally, a network 10 having a packet switching function
, A plurality of terminating devices having a packet assembling / disassembling function, that is, a first terminating device 11, a first host 14 and a second terminating device.
In order to establish a call with any one of the hosts 20, the first terminating device 11 on the calling side to the terminating device on the receiving side (for example, the second terminating device).
You must set the destination to host 20).

That is, the destination of the second host 20 must be known in advance by the first terminating device 11 on the calling side. For example, as shown in FIG. 5A, when communication is performed between the first terminating device 11 on the calling side and the second host 20 on the receiving side, first,
Personal computer communication center 21 from the first terminating device 11 to the window side
The control data such as a dial number is transferred via the network 10, and the call 1 is set between the calling side first terminating device 11 and the counter side personal computer communication center 21.
The personal computer communication center 21 receives various kinds of information that the 11 wants to know from the personal computer communication center 21 and displays them as a menu on the display screen 11a.

Next, from the menu on the display screen 11, the second
The call 2 between the personal computer communication center 21 and the second host 20 is set by selecting the host. Then, the call 3 between the devices that want to communicate with each other by these call 1 and call 2 settings is set.
Is established, and the first terminating device 11 on the originating side and the second host 20 on the terminating side are established.
Enable communication between them and start communication.

That is, as seen in the above personal computer communication,
In some cases, a menu is prepared in the personal computer communication center 21 so that the terminating device on the receiving side can be designated without knowing the destination of the second host 20 on the receiving side.

In this case, the first terminating device on the calling side
The communication function is realized by establishing a plurality of calls between 11 and the terminating device on the receiving side and passing each call.
Therefore, the personal computer communication center 21 needs to set up a plurality of calls, so that a continuous load is constantly applied.

Next, a call deflection facility (function of deflecting a received call to another side different from the calling side) in the network will be described with reference to FIG. 5 (B). When the calling device 31 wants to communicate with the called device 33, the calling device 31 sends a call request (CR) to the network 30.
The network 30 transmits the incoming call (CN) to the destination device 33 based on the CR.

At this time, if the device 33 designated on the receiving side does not want to communicate because it is busy, for example, the device 33 sends a recovery request (CQ) to the network 30, and the network 30 uses the CQ as a basis. The CN is transmitted to the other device 32.

Then, the other device 32 sends an incoming call acceptance (CA) to the network 30, and the network 30 establishes the call only between the originating device 31 and the terminating device 32, and the data (D
T) can be given and received.

[0012]

Therefore, in the conventional technique, a call cannot be established with the terminating device on the calling side unless the destination of the terminating device on the receiving side is known. . In addition, the method using personal computer communication has a problem that the load is increased because more calls than necessary are established in a network having a packet switching function.

It is an object of the present invention to reduce the load by temporarily applying a load to a window device.

[0014]

In order to achieve the above object, as shown in FIG. 1, a network 10 having a packet switching function and a plurality of callers having a packet assembling function and a packet decomposing function in the network 10 or In the communication system in which the first terminating device 11 to the third terminating device 13 and the like on the destination side are connected, after a call is established between the first terminating device 11 on the originating side and the third terminating device 13 on the destination side, The third terminating device 13
The first terminating device which has transferred the destination list indicating the transfer destination of the call to the first terminating device 11 and has received the destination list
11 selects a transfer destination, transfers the destination list to the third terminating device 13 on the receiving side, and receives the third list on the receiving side receiving the destination list.
In order to transfer the call to the destination, the terminating device 13 performs call setup using the switching request, which is a call deflection function, the disconnection confirmation, and the switching notification, so that the second terminating device 12 and the first terminating device 12 in the network 10 are connected. It is configured to realize communication between the terminal devices 11.

[0015]

As shown in FIGS. 1 to 4, according to the present invention, in the network 10 or the online data controller 15 having a packet switching function, the third terminating device 13 on the receiving side or the virtual terminating device in the online data controller 15 is used. A destination list indicating transfer destinations to be transferred to the first terminating device 11 on the originating side from 16
By selecting the transfer destination from (b), even if the first terminating device 11 on the calling side does not know the destination of the second terminating device 12 on the receiving side, the first terminating device and the second terminating device 12 are selected. A call can be established between them.

Therefore, since a call can be established only between the first terminating device 11 on the calling side and the terminating device 12 on the receiving side, a plurality of calls can be established between the first terminating device 11 on the calling side and the second terminating device 12 on the receiving side. It is possible not to complete the call, and it is possible to reduce the load on the network 10 and the online data control device 15.
