The present invention relates to a method for displaying caller information using a mobile terminal which allows a caller to directly input a text for caller indication information when a call is made to a called party.

Today, with the development of mobile telecommunications, the convenience and cost of mobile phones have decreased, making mobile phones a necessity of life, and the number of subscribers has exploded.

Early mobile phones were merely for phone calls, but as the technology of mobile phones developed, various services appeared. Representative services include caller ID service and short message service.

The caller display service is a service for displaying the caller's telephone number on the called party's terminal, but the called party reports only the phone number and has a disadvantage in that the caller cannot be immediately recognized.

To this end, the called party registers the phone number and its name in advance in his mobile terminal, and the mobile terminal checks the caller's telephone number with the phone number stored in the mobile terminal in advance. The name is displayed.

However, the caller name display function using the caller ID service as described above has a disadvantage in that the caller ID must be registered in advance on the called party's terminal, and the name is set and stored accordingly.

In addition, because the caller's mobile terminal is based on the called party's mobile terminal, the calling party's name not stored in the called party's mobile terminal may not be known by the caller's name.

In addition, the caller ID service requires a separate network caller ID node. If the caller sets a name for each called party number, the caller accesses the calling party ID node every time the calling party calls and if there is a caller name stored in the called party number, the caller is called. The name is displayed as the called terminal. This conventional method is inconvenient to use because a network traffic load is generated for each call to the caller display node, and a service user needs to access the caller display node to an environment such as the Internet in order to change the caller display name. There is.

Accordingly, it is an object of the present invention to provide a method for displaying caller information using a mobile terminal that allows a caller to input a simple text such as caller information and a message when the caller makes a call.

According to an aspect of the present invention to achieve the above objects, if the calling terminal receives the call number and caller indication information from the caller after receiving a call command, generating a call setup request message including the caller indication information A caller information display method using a mobile terminal is provided, wherein the caller terminal displays the caller indication information included in the call setup request message and outputs a ring signal.

The call setup request message includes an outgoing call number, an incoming call number, and a caller indication information field. The caller indication information field includes an identification code, content size, protocol, and caller indication information.

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