Description

Method for providing the location information as user absence}

The present invention relates to a method for providing location information when a user is absent using a mobile communication terminal, and more particularly, to provide a sender with location information of a counterpart when a user misses due to a departure of the other party in a call using the mobile communication terminal. It relates to a method for providing location information in absence.

At present, the number of mobile subscribers such as cellular phones and personal communication systems (PCS) is increasing exponentially, and it is now becoming a generalized communication means. Accordingly, in addition to voice calls using mobile terminals, various technologies have been developed. It is becoming.

These technologies include Short Message Service (SMS), which transmits data such as text and characters, voice dialing to dial a specific person by voice, and information using WAP (Wireless Application Protocol) and WAP server. .

Recently, a technique has been attempted to track the location of a base station to which a user first accesses to roughly identify the current location of the user and to provide various information corresponding to the location.

The telecommunications company's central system (switching device, etc.) can identify the location of the base station first accessed by a particular terminal, and sets the location of the first access base station to the current user's location.

In the case of using the location tracking method through the base station, the accuracy is low because the location is tracked with the accuracy of the range covered by one base station.

That is, if a base station is in charge of a radius of 5 km, only the first user accessing the base station can know that only within the area, it is not known where the user is located in that area.

Recently, GPS (Global Positioning System) using satellites has been used to overcome these drawbacks, and the GPS is a method of checking the position of a specific terminal on three satellites and tracking the position of the terminal by triangulation. The user's location can be determined with an accuracy of meters (m).

The real-time local information service based on location tracking displays a serviceable menu on the terminal, and when the user selects one of them, searches the database of the communication server, extracts the results, and provides them to the user through the WAP gateway. Is done in the form of:

Another technique for processing this in the absence of the user is a technique for switching to the mode of leaving a voice or text in the absence of the user, in this case there is an inconvenience because there is no information from the other party from the caller.

As described in Korean Patent Laid-Open Publication No. 1999-059016, a technology for storing voice in the absence of a user is implemented in the terminal, and if the voice information is stored using this voice storage technology, the user is in the auto answer mode when a missed call is placed on the user terminal. It is a technology that delivers the stored predetermined voice information to the other party.

The above-mentioned technology is a technology in which the voice is automatically delivered to the caller by leaving the voice in the absence of the user, but this technology can transmit a lot of information to the caller in its own way, but the terminal user should always leave the voice of his absence If you do not erase the voice left in the past by mistake, there is a dangerous problem that can deliver the wrong information to the other party.

Therefore, the present invention has been proposed to solve the inconveniences of the prior art, a method for providing user location information in the absence of a user to provide the sender with the location information of the other party in the absence of the other party in the call using the mobile communication terminal The purpose is to implement
