Hereinafter, according to the present invention having the configuration described above, the auxiliary antenna device of the portable terminal will be described in detail with reference to the accompanying drawings.

The basic service provided by the mobile communication terminal 200 is to wirelessly communicate with a desired counterpart while moving, and the communication service has a characteristic of always carrying the mobile terminal 200 since it may not occur at any time. However, since the time that communication takes place is extremely small, various additional services are used to improve some of the problems with low utilization and utilization rate of the mobile terminal.

According to the present invention, when playing a game with a mobile terminal converged in a game (GAME) among additional services, the antenna is wrapped by the hand controlling the game, and thus the mobile communication radio signal cannot be received and an urgent call signal is received. If this is not done, it is a technique of the present invention to improve the problem of low reliability since it does not use the basic service of the mobile terminal.

The controller 150 of the portable terminal reads an operation program, an application program for basic services and various additional services, and corresponding operation data from the memory unit 170 when operating power is supplied. (READ) Loads and waits.

In the standby state as described above, the control unit 150 controls the high frequency switch unit 120 to set the path (PATH) of the high frequency unit 130 and the main antenna 100, the main antenna 100 Is received by the radio frequency is applied to the high frequency unit 130 by the path set by the high frequency switch 120 is analyzed and processed, and output through the entry and exit unit 140, the entry and exit unit 140 The baseband signal applied to the baseband signal is up-modulated by the high frequency unit 130 to a high frequency (RF) signal, and is transmitted to the main antenna 100 through the high frequency switch unit 120 so that it is wirelessly transmitted.

The controller 150 analyzes a control command applied from the entry / exit unit 140 in a standby state in which the portable terminal 200 is not used for mobile communication, and determines that the control unit 150 is a game control command. ) To activate and control the game, and outputs the selected game to the entry / exit unit 140, and controls the game operation according to a control signal applied from the entry / exit unit 140.

The entrance and exit unit 140 includes a joystick unit 230, and the joystick unit 230 controls the progress and operation of the game because the user directly controls by hand, the game controlled and progressed and operated as described above The output unit is displayed on the display unit included in the entry / exit unit 140.

In the state where the game is in progress as described above, the joystick unit 230 constituting the entry and exit unit 140 should be wrapped and controlled by the hand, in the state of controlling the joystick unit 230 as described above, the hand is the main antenna Since the envelope 100 is wrapped, the reception performance of the main antenna 100 is reduced, so that even if there is a radio call from the counterpart, the high frequency unit 130 does not recognize and analyze it.

At this time, the sensor unit 180 detects a hand contact state, and the signal detected by the sensor unit 180 is applied to the controller 150.

In the above-described method configuration, it is determined whether a control command for selecting and operating a game is input by the controller of the portable terminal in a state where it is operated as a communication wait, and operating power is applied by the controller 150. Setting and maintaining a standby state that does not operate an additional service and a communication service in a state (S100); The controller 150 of the process (S100) is a standby process consisting of a process (S110) for determining whether to operate the game additional service by analyzing the input control command,

If it is determined that the game operation in the waiting process, the game mode is set, the selected game is operated, and it is determined whether a signal detected from the sensor is applied, and the game additional service is operated by the controller 150 of the waiting process. If it is determined that, to set the game mode (GAME MODE) and running the selected game to operate (S120); The control unit 150 of the process (S120) is a sensor process comprising a process (S130) of monitoring the sensor unit 180 to determine whether a user contact signal is detected and applied,

When the touch detection signal is applied in the sensor process, the high frequency switch unit 120 is controlled to switch the high frequency unit and the auxiliary antenna unit to set a path, and to receive and analyze the radio signal. The sensor unit 180 is controlled by the controller 150. When it is determined that the user contact signal is detected and applied, the high frequency switch unit 120 is controlled to block the main antenna path PATH connected to the high frequency unit 130 and the auxiliary antenna 110 path ( PATH) switching (SWITCHING) setting step (S140); The control unit 150 of the process (S140) is composed of a switching process consisting of a process (S150) for receiving and analyzing a radio signal through the auxiliary antenna (110).

Hereinafter, according to the present invention having the configuration described above, the auxiliary antenna method of the portable terminal will be described in detail with reference to the accompanying drawings.

The control unit 150 of the mobile communication terminal 200 is set to a standby state that can immediately perform the control command is applied in the state that the operating power is applied, do not operate the communication and additional services (S100) As described above, the controller 150 setting the standby state analyzes a control command applied through the entry / exit unit 140, and thus determines whether to play a game (S110).

If it is determined that the control command to play the game in the step (S110), the controller 150 activates the game unit 160 to set the game mode (GAME MODE), and load and operate the selected game (GAME) (S120).

The controller 150 of step S120 monitors the sensor unit 180 and determines whether a signal detecting a contact state of the user's hand is applied (S130).

In the process (S130), when the touch detection signal is applied from the sensor unit 180, the controller 150 controls the high frequency switch unit 120 so that the high frequency unit 130 is the main antenna 100. Blocking the state connected to, and controlling the switching (SWITCHING) so that the state connected to the auxiliary antenna 110 is set (S140).

The high frequency unit 130, which is connected to the auxiliary antenna 110 through the path set by the high frequency switch unit 120 in the step S140, receives and analyzes a radio signal, and when there is a call of the other party, the controller ( Since the respective signals are output to the 150 and the entry / exit unit 140, the user recognizes the call of the opponent even while the game is in progress (S150).

The present invention having the above-described configuration has the advantage of receiving and confirming the call of the opponent immediately because the reception sensitivity is secured through the auxiliary antenna 110 even in a state of being engaged in a game with a game convergence mobile terminal. There is this.

Hereinafter, the shape of the sensor structure of the mobile terminal according to the present invention will be described with reference to FIG. 7.
