The present invention relates to a method and a server for providing an incoming call notification service and a mobile communication terminal for the same. More specifically, when a mobile terminal user requests an incoming call notification after ending a call with a caller, the caller transmits the caller's call information after a certain time, so that the user may be caught while driving or meeting. The present invention relates to a method and a server for providing an incoming call notification service for preventing the user from forgetting to make a short call to an incoming call and returning the caller after a while, and a server and a mobile communication terminal therefor. .

As computers, electronics, and communication technologies have advanced rapidly, various wireless communication services using wireless networks have been provided. The most basic wireless communication service is a wireless voice call service that provides a voice call to a mobile terminal user wirelessly, which can provide a service regardless of time and place. In addition, while supplementing voice call service by providing a text message service, recently, a wireless Internet service that provides an Internet communication service through a wireless communication network to a user of a mobile communication terminal has emerged.

As a result of the development of mobile communication technology, the service provided by the mobile communication system is developing not only a voice service but also a multimedia communication service for transmitting data such as circuit data, packet data, and the like.

Recently, the IS-95C network, which has evolved from the existing IS-95A and IS-95B networks, transmits up to 307.2 Kbps, which is much faster than the 14.4 Kbps or 56 Kbps data rate that can be supported in the IS-95A and IS-95B networks. It offers wireless internet at speed. In particular, by using IMT-2000 service, it is possible to provide various multimedia services (AOD, VOD, etc.) at higher speed as well as improving existing voice and WAP service quality.

As the mobile communication network has evolved, various services have been on the rise to satisfy various needs of users of mobile communication terminals and to provide convenience of using terminals.

A Caller Identification (CID) service that announces the caller's phone number is also a service that extends over that line.

When the mobile communication network receives the call connection request signal from the calling terminal (S100), the home location register (HLR: Home Location Register) retrieves the number of the calling terminal and the called terminal (S102), and the called terminal is connected to the calling party number display service. It is determined whether or not the subscription (S104).

As a result of determination, when the called terminal is not subscribed to the service, a general call processing procedure is performed (S106).

However, if the service is subscribed to try to connect the call to the called terminal (S108), if there is a response from the called terminal transmits the calling terminal number to the called terminal (S110).

If there is no response from the called terminal, the call is disconnected from the calling terminal (S112), and the calling party number is configured in the form of a short message and transmitted to the called terminal (S114).

By using the caller ID display service, the called party can not only know who the caller is, but can also know who the call is from through the missed message even when the caller is not answered.

However, the out-of-office message provided by this caller ID service is provided only when the called party does not answer the call.If the called party receives the call but decides to call later due to urgent business such as driving or meeting, It does not provide a more active function to remind the called party that the call has come.

In order to solve this problem, the present invention, when the user of the mobile communication terminal terminates the call with the caller requests the incoming call notification, by sending a caller's call information after a certain time, the user is driving or meeting A method and server for providing an incoming call notification service to prevent the user from having to make a short call on an incoming call during an urgent business, hang up, and then forget to reply to the caller after a while.
