The present invention relates to an earset and a method for retrieving a phone book and a short message of a mobile communication terminal through Bluetooth communication. In particular, a phone number or a received short message stored in the mobile communication terminal can be easily retrieved at any time through Bluetooth communication. It relates to an earset and a method that can be.

In general, the users of the mobile communication terminal stores the phone number of the other party in the phone book inside the mobile communication terminal so that it can be checked at any time. In addition, users use a speed dial function to avoid the hassle of inputting a phone number of a counterpart having a relatively long numeric array each time a call is made to the other party through a mobile communication terminal. Store the other party's telephone number in the mobile communication terminal.

As described above, a general method for storing a phone number in a mobile communication terminal will be described with reference to FIG. 1.

Referring to FIG. 1, first, a user opens a flip or folder of a mobile communication terminal and then presses a menu key to input a desired phone number into the mobile communication terminal (S101), and stores the phone number entered by the user in the mobile communication terminal. In order to press the save button (S102), the mobile communication terminal displays a screen for receiving a user name mapped to the telephone number entered on the LCD (S103).

Thus, when the user name is displayed on the screen, when the user inputs the user name of the phone number to be stored (S104), the mobile terminal determines that the user of the input telephone number is a group name (group) associated with the mobile terminal user. A screen for selecting can be displayed (S105).

At this time, when the user selects a group by pressing a button of the mobile communication terminal (S106), the mobile communication terminal to specify whether the input telephone number is a number for the home, work place or pager, etc. to store the input telephone A screen for displaying a storage location of the number is displayed (S107). Here, the user may not select the corresponding group of the input telephone number but instead select the "not designated" list from the displayed list.

If, in the group selection process (S106), the user selects a "not specified" list without selecting a specific group, the mobile communication terminal displays a screen for selecting a storage location.

Subsequently, when the user selects one storage location by pressing a button of the mobile communication terminal (S108), the mobile communication terminal stores the input telephone number, the user name of the number, the corresponding group and the storage location, and displays the stored contents. Display on the screen to inform the user (S109).

However, when the user searches for a phone number stored in the mobile communication terminal as described above during the call, there is a problem that the call must be stopped.

As the mobile communication service spreads widely, information exchange using a mobile communication terminal is becoming the most important communication means in everyday life. In particular, unlike general fixed line telephones, the mobile communication service provides a text message or a short message service (hereinafter, referred to as SMS) in addition to voice calls.

SMS is a service that a caller writes a text message (SM) using a mobile communication terminal and delivers it to the receiver's mobile communication terminal. The SMS is an information transmission method in a situation in which the receiver cannot make a voice call or when the power is turned off. It is usefully used.

Short service message server (SMSC) is used for this service. The short message service center (SMSC) is a mobile terminal (MS) and a mobile terminal period, or between a mobile terminal and a short message entity (SME). It is a communication service center that delivers in the form of limited text messages (short text), and has both a real-time transmission and a forwarding function of storing and forwarding a message until the receiver can receive it.

The SMSC is a node having a unique signaling point code (SPC) in a signaling system 7 (SS7) network, connected to a home location register (HLR) and a mobile service center (MSC) to determine the location of a receiver, and public PLMN (PLMN). It has a function of delivering a short message to mobile subscribers through Land Mobile Network.

On the other hand, in recent years, one mobile communication subscriber owns several terminals, and there are cases in which a call received from a specific terminal needs to be received from another mobile communication terminal or a wired telephone terminal. "Call forwarding service" is provided.

This call forwarding service applies only to voice calls and not to text messages. That is, it would be convenient if a call forwarding service for delivering a text message received to a specific terminal to another mobile communication terminal could be used.

When the call forwarding service of the text message is implemented using a conventional SMS system, the following steps are performed.

When the short message to be transmitted to the specific terminal is received by the short message service center (SMC), the SMC requesting status information of the terminal to the home location register (HLR); Checking a state of a corresponding terminal in the HLR and determining whether a short message is activated; When the call forwarding service is activated in the terminal, the HLR transmitting corresponding terminal state information (location information) and call forwarding service activation information to the SMC; Requesting, by the SMC, status information (location information) of a terminal designated as a call forward again to the HLR based on the information received from the HLR; The HLR transmitting the status information of the terminal designated as the call forward back to the SMC; SMC converts the received short message into a predetermined signal transmission form and transmits the short message to an exchange (MSC); The MSC sends the received short message to a terminal designated as a call forward; Transmitting from the MSC to the SMC whether the short message is successfully transmitted to the terminal designated as the call forwarding.

Therefore, using the conventional system can implement the incoming message service of the text message, but it is cumbersome, cost-effective and inefficient call forwarding to add the short message incoming service item to the signal transmission method between SMC, HLR, MSC The transmission path of information about is complicated and its stability is also low.

In addition, when a short message is received in a mobile communication terminal in a call, the user has to disconnect the current call to confirm the received short message.

Accordingly, the present invention has been made to solve the above problems, to provide an earset and a method that can search for a phone number without a call interruption during the call by searching the phone number stored in the mobile communication terminal through Bluetooth communication. There is a purpose.

An object of the present invention is to provide an earset and a method for confirming a short message received at a mobile communication terminal through a Bluetooth communication without disconnection during a call.
