The present invention relates to a missed call connection method of a mobile phone terminal. In particular, in a counterpart number display service that displays a counterpart phone number, a missed call connection enables a user to connect a missed call that cannot be received by the user with a single call key. It is about a method.

The current missed call is a service that displays the phone number of the other party at the same time as the customer when a call is made. This is useful when a threat or prank call is received or when the customer does not want to answer the call.

As such, the relative number display service is applied only to the applicant in both directions, and his / her number is displayed to the other party as well as the telephone.

In addition, there is a service where the other party's phone number is displayed regardless of whether or not the other party is applying. You will need to provide proof to apply for this service.

Currently, this service is provided only when a phone is communicated with a specific communication company (eg 019PCS phone), but when a phone number is provided by another communication network such as a landline phone, a caller ID is displayed for all phones. It is believed that this is possible.

In the conventional missed call connection method, when a missed call is received, the missed call phrase "one call came" is displayed and the caller ID (Caller ID) is stored in the recent call list (S11, S12).

The user checks the missed call phrase (S13), presses the search key to connect to the caller's phone number, selects the most recent call list from the search list in which the caller's phone number is stored (S14, S15, S16), and calls Press key to be connected to the sender (S17, S18).

However, in the conventional missed call connection method, when a call is received, the received phone number is stored in the recent call list, and the user has to find it through several steps. By connecting and making a call, the user is inconvenient with several levels of searching.

The present invention has been made to solve the above-mentioned problems, and when the missed call is received in the mobile terminal, the phone number of the other party is displayed on the screen and the phone number is stored in a separate transmission buffer to allow the user to make a call. An object of the present invention is to provide a missed call connection method of a mobile phone terminal, which allows a call to be made to the other party by pressing a key.

Missed call connection method of a mobile phone terminal according to the present invention for achieving the above object,

(a) receiving the caller's call and storing the caller's telephone number;

(b) determining whether the recipient has received the call;

(c) storing the caller's telephone number in the recent call list when the call is received;

(d) if the missed call is not received after step (b), displaying the missed call phrase and the caller's phone number on the screen;

(e) storing the sender's telephone number in the transmission buffer after step (d);

(f) if the call key is pressed after step (e), the method proceeds to the step of connecting to the caller's telephone number.

In addition, the present invention is characterized in that when the number of missed calls is more than two, the phone number of the last received caller is read and displayed on the screen, and the phone number is stored in the transmission buffer so that the call key can be connected. do.

Hereinafter, with reference to the accompanying drawings. Figure 2 is a block diagram of a mobile phone terminal employed for the present invention, Figure 3 is a flow chart showing a first embodiment of the missed call connection method of the mobile phone terminal according to the present invention, Figure 4 is FIG. 5 is a flowchart illustrating a second embodiment of a missed call connection method of a mobile phone terminal, and FIG. 5 is a view illustrating a screen progress procedure in a missed call connection method of a mobile phone terminal according to the present invention.
