Abstract

PURPOSE: A system for selectively calling a caller through a mobile terminal and a method therefor are provided to effectively transmit a specific voice message to a connection rejector without transmitting a call connection request signal from the connection rejector to a callee. CONSTITUTION: A connection rejection setup terminal(HP1) selectively inputs a mobile terminal number about a specific caller so that a call connection from the corresponding caller is rejected and registers a guidance message for informing a call impossible cause. A connection rejection object terminal(HP2) is set up as a connection rejection object through the connection rejection setup terminal(HP1) for receiving the call impossible guidance message from the connection rejection setup terminal(HP1) and confirming the call impossible cause. An MSC(Mobile Switching Center)(16) receives code information for setting a connection rejector and message selection code information for writing the call impossible message from the connection rejection setup terminal(HP1) through BSs(Base Stations)(10A,10B), mobile communication relay stations(12A,12B), and a BSC(Base Station Controller)(14), registers received code information and message selection code information. If the connection rejection object terminal(HP2) calls a telephone number of the connection rejection setup terminal(HP1), the MSC(16) processes the previously registered call impossible message as a voice guidance information format or a character information format on the basis of code information and transmits the processed call impossible message to the connection rejection object terminal(HP2).

Description

Caller's choice calling system through mobile terminal and method thereof {SYSTEM AND METHOD FOR SELECTING CALLING USER USING A MOBILE DEVICE}

The present invention relates to a caller-selected call system and a method through a mobile terminal, and more particularly to selectively deny a specific caller's mobile number and to output a preset voice message only to the caller set as the access denial. The present invention relates to a caller-selected call system and method through a mobile terminal that effectively delivers a specific voice message to a caller while preventing a call connection request signal from the caller to be sent to a called party.

As is well known, due to the recent development of information and communication technology, the development of information providing technology that provides real-time information to various subscribers through at least one host server through a remote data communication network is actively underway.

Based on this, in recent years, information selection technology and compression technology are being developed to more easily access peripheral technologies such as cache memory expansion technology to provide accurate information to subscribers more quickly and subscribers' tastes and preferences. The situation is also accelerating the development of various electronic devices and their programs.

Meanwhile, in recent years, the spread of personal mobile communication has been exponentially performed. In general, a mobile communication system is composed of PCS (Personal Communication System), CDMA, or GSM (Global System Of Mobile Communication). The portable communication terminal enables the user to carry out voice calls and text communication with other mobile communication terminals or landline phones while the user is moving.

In the case of a portable mobile communication terminal applied to such a mobile communication system, a subscriber can make a voice call or text communication with a desired party regardless of time and place without having to move to a location where a separate landline telephone terminal is installed. Because it can be performed wirelessly, it is possible to make a quick call connection with the other party in case of urgent or important contact.

However, in the above mobile communication system, the blind spot of the personal mobile terminal is that when the caller requests a call even when the caller does not want to receive a call or does not want to receive a call from a specific caller, the call connection signal is continuously transmitted, so that the called party is often inconvenient. There was a problem.

In addition, there is a problem that there is no separate solution even when the called party may be very difficult when a call from a particular caller is received according to the presence of a third party.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances of the prior art, and selectively sets a mobile number of a specific caller to deny access, and outputs a preset voice message only to the caller set as the deny access. An object of the present invention is to provide a caller selection call system through a mobile terminal and a method for transmitting a voice message so that a call connection request signal from the access rejector is not transmitted to the called party.
