How to provide caller ID search service for incomplete calls {METHOD FOR PROVIDING A CALLER IDENTIFICATION RETRIEVAL SERVICE IN CASE OF INCOMPLETE CALL}

The present invention relates to a method for providing a calling party number search service for an incomplete call in which a call is terminated while a called subscriber does not answer in a mobile communication network.

Currently, Caller Number Information Presentation (CNIP) is widely used in mobile phones as well as general telephones.

Caller ID display service is a service that allows the called party to display the calling party's telephone number and name on the called party's phone or the calling display terminal before the telephone call starts. In other words, it refers to a service that provides the caller with information of the caller, such as the caller's telephone number and name.

When using the caller ID display service, the caller's phone number is displayed on the called party's phone even when the called party is not in a call or during a call. You can also check the phone. You can pick up the other person and answer the call, or check the incoming call again.

Conventional techniques related to such a caller ID display service (or caller ID search service) are as follows.

First, as a caller number retrieval service technology in a private branch exchange (PBX) system operated by companies and institutions, domestic patent registration No. 10-0255370 (name of the invention: "storing and retrieving the caller number in the private exchange system) Method "), and Korean Patent Publication No. 2001-0044618 (name of the invention:" apparatus and method for displaying caller identification information of private switching network ").

The domestic patent registration No. 10-0255370 (name of the invention: "method of storing and retrieving calling party number in a private exchange system") is a private exchange system in which a subscribed station is busy or no answer. When in the state of the present invention relates to a method that can query the caller ID of the caller.

The domestic patent registration No. 10-0255370 is a memory means implemented in the private exchange by detecting the caller number of the calling party corresponding to the trunk line call when there is a trunk line call that is received when the called party and the extension is busy. Store in If the calling party number inquiry input from the called party extension, the stored calling party number is characterized in that the calling party number query method is displayed on a predetermined display means implemented in the called party extension terminal.

In Korean Patent Laid-Open No. 2001-0044618 (name of the invention: " apparatus and method for displaying caller identification information of private switching network "), caller identification information can be displayed on a computer monitor screen corresponding to all telephones connected to a private exchange. It provides a caller identification information display device that can be.

The caller ID search service provided by the domestic patent registration No. 10-0255370 and the domestic patent publication No. 2001-0044618 is a technology used in a telephone using a private exchange, and can be applied to a mobile phone terminal in a mobile communication network. Search related technologies are as follows.

In a mobile communication network, a voice message system (VMS) is used to record a voice message when a called party is busy, on a missed call, or when the wireless terminal is turned off (hereinafter referred to as an incomplete call).

1 is a system configuration diagram for recording a voice message with a voice message system (VMS) for an incomplete call in a conventional mobile communication network.

Referring to FIG. 1, a system for recording a voice message with a conventional voice message system (VMS) for an incomplete call includes a caller 100, an originating exchange 110, a destination exchange 120, and a home location register (HLR); Home Location Register (130), voice message system (VMS) 140, base station controller (BSC) 150, base station (BTS) 160 and destination subscriber 170. Hereinafter, a description of call processing in a general mobile communication network will be omitted, and a description will be given mainly on a process of recording a voice message with a voice message system (VMS) for an incomplete call.

In the conventional case, the originating exchange 110 detects whether an incomplete call such as a call subscriber is busy or absent or a terminal power off state occurs, and determines whether the called subscriber is a VMS subscriber. Only if the VMS subscriber, the caller 100 is told that the call is transferred to the VMS. In this case, the caller 100 ends the call without recording in the voice message system (VMS) 140 due to the rejection or inconvenience of recording.

In case of such an incomplete call, the voice message of the caller can be confirmed only when the voice message system (VMS) 140 is recorded. That is, when the caller disconnects the phone due to the charge burden of the VMS, the called party has no problem knowing who the call is for him.

Such a technique for delivering a calling party number to a called party when a conventional incomplete call occurs is disclosed in Korean Patent Laid-Open Publication No. 2000-0074674 (name of the invention: "a method of transmitting a calling party number and calling party information and a mobile phone terminal using the same").

The location of the subscriber is determined by the responsible mobile service switching center (MSC). In addition, MSC checks whether the called party is subscribed to the calling party number service by the Home Location Register (HLR) and Visitor Location Registration, which has all databases related to the subscriber. The number and the caller information are transmitted to the called party terminal through the base station controller (BSC) and the base station (BTS). The called party's terminal compares the calling party's telephone number transmitted from the base station (BTS) with the telephone number previously stored in the terminal memory. If there is the same telephone number, the called party transmits a ring tone designated by the telephone number and at the same time. Display information.

In Korean Patent Laid-Open Publication No. 2000-0074674, caller information such as a caller's telephone number is transmitted from the MSC to a called party's terminal, and the called party's terminal displays caller information such as the called party's number in real time.

The caller information retrieval technique in the conventional mobile communication network as described above may inform the called party's caller's telephone number and the like even when the called subscriber is busy, absent, or when the terminal is powered off.

However, not only the caller information is notified to the called party in real time, but if the called subscriber does not use the wireless terminal for a long time, the caller information is stored in a certain place so that the called subscriber can be registered with the caller's phone number whenever necessary. There is a need to be able to verify caller information.

Accordingly, the present invention has been made in view of the above necessity of providing the prior art, and when the called subscriber is busy or absent or an incomplete call such as a terminal power off occurs, the called subscriber uses a wireless dedicated browser. It is an object of the present invention to provide a method and system for retrieving a caller number that can check caller information including a caller number anytime and anywhere.
