Abstract

PURPOSE: A method for processing a call in a telephone communication system is provided to improve the call success rate by terminating one user's call connection attempt immediately and responding to the other user's call connection attempt in case that a call is simultaneously attempted between the two calling/called users. CONSTITUTION: If a calling user pushes the call button after inputting the other side's phone number(S101), a telephone communication system judges whether the terminal of the inputted phone number is in a hook-off state(S102). In case that the called terminal is in the hook-off state, the system judges whether the called user is attempting a call(S103). If it is judged that the called user is attempting a call, the system traces a phone number to which the called user tries to make a phone call(S104). Then the system judges whether the traced phone number is identical to the calling user's phone number(S105). In case that the two phones' numbers are identical, the system immediately ends the calling user's call connection attempt(S106) and makes call connection established between the two users(S107).

Description

Call handling method of telephony system {CALL PROCESS METHOD FOR TELECOMMUNICATION SYSTEM}

The present invention relates to a call processing method of a telephony communication system, and in particular, when attempting to make a call between a called user and a calling user at the same time, immediately terminates a call connection attempt of one side and responds to a call connection attempt of another user. The present invention relates to a call processing method of a telephony communication system which can improve a call success rate.

In general, in wired and wireless telephony services, the quality of service is improved by increasing the call success rate through various methods such as facility investment in base stations, lines, and technology development.

However, when the called user and the calling user try to talk to each other at the same time while using the service, even though both sides have a willingness to call and have the necessary infrastructure for the call service, a call cannot occur. This can cause a very uncomfortable situation from the user's point of view.

That is, in the conventional telephony communication system, only the caller and the caller are not distinguished from each other, and only the caller is checked, and when the caller is busy, the caller unconditionally transmits a caller signal so as not to make a phone call or attempts to call again after a predetermined time. There is a problem causing inconvenience to the user.

Therefore, the present invention was created to solve the above conventional problems, when attempting to simultaneously call between the called user and the calling user, immediately terminates the call connection attempt of one side and the other end user's call connection It is an object of the present invention to provide a call processing method of a telephony system that can improve a call success rate by responding to an attempt.

The present invention for achieving the above object comprises a first step of determining whether the called terminal is a hook-off state to which the calling user is trying to connect the call; Determining whether a call connection attempt is being made when the called terminal is in a hook-off state; A third step of tracking the telephone number of the call connection attempt when the called terminal attempts to connect the call; A fourth step of determining whether the tracked telephone number matches the calling user's telephone number; When the called party's telephone number and the calling user's telephone number are the same, it is characterized in that it comprises a fifth step of immediately terminating the call connection attempt of both sides to make a call connection between the two sides.

1 is a flow chart showing a call processing method of the telephone communication system according to the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First of all, in adding reference numerals to the components of each drawing, it should be noted that the same components have the same reference numerals as much as possible even if displayed on different drawings.

Also, in the following description, numerous specific details, such as specific processing flows, are set forth in order to provide a more general understanding of the invention, and it is to be understood that the invention may be practiced without these specific details. It will be obvious to them.

In addition, detailed description of well-known functions and structures which are determined to unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a flowchart illustrating a call processing method of a telephony communication system according to the present invention. In case that the called party is determined that the called party is busy on the call attempt of the calling party, whether the calling party and the receiving party are the same phone number. Comparing and determining the termination of the call connection of one side is further included.

That is, when the exchange determines that the called party is busy on the caller's attempt, the called party's phone number (ⓐ), the called party's phone number (ⓑ), and the calling party The user's telephone number © and the calling user's telephone number ⓓ are detected / compared.

Accordingly, the phone number ⓐ the called party is trying to call and the phone number ⓒ of the calling user are the same, or the phone number ⓓ the calling party is trying to call and the phone number of the called user ( If ⓑ is the same, it is determined that there is a mutual will of each other.

Therefore, by immediately terminating the call connection attempt of the user of one side (calling side) and responding to the call connection attempt of the other side (receiving side) user, the call between both sides can be made.

Referring to Figure 1 described in more detail the process as follows.

First, when the calling user inputs a counterpart (called party) phone number to be called and then presses a call key (S101), it is determined whether the terminal of the input called party number is in a hook-off state. (S102).

As a result of the determination, if it is not in the hook-off state, a general call processing process may be performed to make a call to each other (S109).

As a result of the determination, if the called terminal is in the hook-off state, it is determined whether a call is being attempted (S103).

That is, it is determined whether the called terminal user is waiting for a call connection by pressing a telephone number and pressing a call button.

If the called party is not attempting to talk, the caller sends a busy signal to the calling party (S108). If the called party is trying to call, the called party tracks the telephone number being attempted to make a call (S104).

Next, it is determined whether the tracked telephone number matches the calling user's telephone number (S105).

As a result of the determination, if the called party's telephone number to which the call is trying to connect does not match the calling party's telephone number, the calling party sends a busy signal to the calling party (S108), and if the two phone numbers match, the calling user. Immediately terminate the connection attempt (S106), so that the call connection is made between both sides (S107).

Such a phenomenon may occur when the called user attempts to make a call in the meantime because the call setup does not take place immediately after the calling user attempts to make a call and the call setting takes a predetermined time. In the present invention, when both parties attempt to make a call to each other, it detects this and terminates the call connection attempt of the side who attempted the call later in time, and responds to the call connection attempt of the other side.

If both sides attempt to make a call at the same time, one side may randomly terminate the connection attempt, and may further add a process of transmitting a guide message to the side that terminates the call connection attempt.

As described above, the call processing method of the telephone communication system of the present invention immediately terminates a call connection attempt by one end user and responds to a call connection attempt by another user when simultaneously making a call between the called user and the calling user. By doing so, it is possible to improve the call success rate and improve the user's haptic quality of the wired / wireless telephone service.
