Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic incoming call system when a telephone set during a call is changed, and particularly by operating from a telephone set to be transferred in a different communication network,
The present invention relates to an automatic call reception method when a telephone is changed, which can take over a call state.

Mobile phones usually operate on a battery which is an independent power source. Therefore, when the power battery is exhausted, the call becomes impossible. Further, the mobile phone usually does not have a roaming function for performing communication across different communication networks (particularly fixed network). Therefore, the call cannot be made except in the communication network to which it belongs.

As described above, it is convenient if another telephone can be used to take over the telephone call of the original telephone when the telephone becomes incapable of calling. However, in this case, a redundant operation is required. Instead, it is desirable to be able to continue charging the original phone.

[0004]

2. Description of the Related Art There is a call waiting service that allows a telephone to be changed during a call. According to the call waiting service, it is possible to receive an incoming call at a telephone during a call, and hold a call during a call at the telephone during a call so that a call can be answered and communicated.

FIG. 12 shows an outline of the call waiting service. (A) is an incoming call to a telephone during a call, (b) is a hold of the telephone during a call,
(C) shows holding of the telephone that has received the call.

In FIG. 12 (a), if the telephone set A permits the call waiting service, the telephone set C can receive a call from the telephone set A while the telephone set A and the telephone set B are in communication. .

In this case, the subscriber of the telephone A is the telephone A
By operating (sending a call switching signal to the exchange), as shown in FIG. 12B, it is possible to put the telephone B, which has been in the call up to that time, into the hold state.
Subscribers can talk to phone C.

Further, when hooking is carried out again on the telephone set A, as shown in FIG.
Is put on hold, and the subscriber of the telephone set A can talk with the telephone set B.

[0009]

In the call waiting service, it is possible to respond to an incoming call and communicate by receiving an incoming call at a telephone during a call and holding the active call. However, in the present invention, It is not possible to make an automatic call when the target telephone is changed.
In addition, it is troublesome because it is necessary to perform a response operation to the interrupted call and a release operation of the old telephone. Further in this case,
The old telephone cannot be charged because the telephone using the call waiting service is charged.

As another method, there is also a method in which the call is once terminated and the call is made again from another phone. However, this method has many parts to be hand-held and means for overcoming the communication obstructing factor. In addition to the call waiting service, it is not possible to charge the disconnected telephone.

As described above, no matter which method is used, it is necessary to operate an extra telephone such as a call disconnecting procedure of the telephone, so that a telephone call cannot be made in a short time, and the telephone whose telephone has been disconnected is charged. There is a problem that you can not.

The present invention is intended to solve such a problem of the prior art, and when one of the telephones in a call is changed to a telephone of a different communication network, an extra operation such as a call disconnecting procedure is performed. There is no need to do this, you can talk in a short time, there is no need to end the call, and it is possible to automatically charge the original phone that was disconnected. Has an aim.

In this case, the telephone 5 makes a call and sends to the exchange 6 of the communication network information indicating that an automatic incoming call to the telephone 2 is requested.

Based on this information, the exchange 6 causes the telephone 5
It identifies that the outgoing call is intended for an automatic incoming call, and sends a message requesting the automatic incoming call to the exchange 7 of the communication network in which the telephone 2 is accommodated.

When the exchange 7 receives this message and identifies that it is a message requesting an automatic incoming call, it makes the outgoing call to the telephone set 2 and puts the telephone sets 5 and 2 into a call state. At the same time, the exchange 7 requests the exchange 8 housing the telephone 3 to disconnect the call, so that the exchange 8 disconnects the call from the telephone 3.

When the telephone 5 issues a disconnection request at the end of the call, the exchange 6 requests the exchange 7 to disconnect the call, whereby the exchange 7 disconnects the call from the telephone 2 to recover.

As described above, according to the method of the present invention, when it is necessary to change the telephone set during a call, the telephone set at the change destination is operated so that the telephone set during the call is not required to operate. The call status can be taken over.

(2) In this case, when the exchange 8 of the first communication network disconnects the call of the telephone 3, the exchange 7 notifies the exchange 6 of another communication network of subscriber information about the telephone 3,
The exchange 6 edits the inter-network charging information based on this information and notifies it to the first communication network.

As a result, in the first communication network, the charging information in another communication network can be taken over so that the telephone 3 that has disconnected the call can be charged and the telephone 5 that is the destination of the call can be prevented from being charged. .

(3) Further, in this case, the special telephone number can be used as the information transmitted from the telephone 5 of the change destination and indicating that the automatic incoming call is requested.
