The present invention relates to a reservation call processing system during a call and a control method thereof.

In general, a telephone service using a PSTN has a function of requesting a call according to a reserved call after a call is terminated and a call with another telephone is terminated.

This call reservation function was limited at the time of origination. In other words, when the other party is busy, the call is reserved through a specific operation.When the other party goes to idle, callback is called back to the caller. It is supposed to dial.

This is because the call reservation is set at the exchange and the exchange monitors the receiving party's status and notifies the caller when the other party goes to standby.

There is no problem with the prior art itself. It is simply to implement a service in a different situation differently from the existing method.

When referring to the prior art based on the present invention. When a new call arrives during the call, the caller will be able to answer the newly received call by acknowledging the other party. After answering, 'I'll call you later' or forcibly reject the incoming call and end the existing call and forget that the call came.

When a terminal connected to a private exchange or a terminal connected to a general trunk line exchange sends a guide message for a call received during a call, it is automatically sent to the caller after the call is terminated to reserve the call without any action. It is a function to make it possible.

Therefore, the present invention is to solve the above-mentioned conventional problems, an object of the present invention is to call a reservation call to the terminal requesting the incoming call after ending the current call when a new call is received during the call The present invention provides a reservation call processing system and a control method thereof.
