2 is a diagram illustrating a control flow performed by a portable device for line release protection according to an embodiment of the present invention.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a portable device for a wireless telephone that automatically connects a line when it is detached from a charger, and more particularly, to a method of protecting a line release when a line is detached from a charger.

In general, the line connection of a portable device provided in a wireless telephone is implemented to be performed by a user pressing a call key requesting a line connection or to be automatically performed when the portable device is separated from the charger for the convenience of the user.

That is, as mentioned above, in the related art, an automatic connection method which automatically connects a line when the portable device rings from a charger to call a counterpart or a caller who wants to call, and automatically connects a line after the user lifts the portable device. There is a manual connection method for connecting a line when a call key is pressed.

As described above, the conventional portable device uses a combination of the two methods described above, and when the user using the manual connection method attempts to make a call using the portable device using the automatic connection method, the mobile device unknowingly presses a call key. The disconnection of the connected line occurred.

Accordingly, an object of the present invention is to provide a method for connecting a line even if a call key is input before the line is connected.

Another object of the present invention is to provide a method for maintaining a connected line by ignoring a call key input before a predetermined time elapses even if the line is connected.

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

The configuration of a portable device provided in a wireless telephone according to an embodiment of the present invention is as shown in FIG.

Referring to FIG. 1, a configuration of a portable apparatus according to an exemplary embodiment of the present disclosure will be described. The controller 11 controls overall operations of the portable apparatus. It also includes a ROM for storing program data therein and a RAM for temporarily storing data generated during program execution. In particular, the controller 11 performs control for line release protection according to an embodiment of the present invention. The key input unit 12 includes a plurality of keys including a call key for requesting a line connection for a call, and provides the control unit 11 with key data generated according to a user's key operation. The display unit 13 displays various operation modes and current states of the portable device under the control of the controller 11. The duplexer 15 is connected to an antenna and separates a transmission RF signal and a reception RF signal transmitted and received by the antenna. The transmitter 14 converts the control data output from the controller 11 and the audio signal generated from the microphone MIC into a modulation and an RF signal and outputs them to the duplexer 15. The receiver 16 frequency converts and demodulates the received RF signal output from the duplexer 15. The audio signal output from the receiver 16 is output to the speaker SPK, and the control data is output to the controller 11. The frequency synthesizing unit 17 generates the transmission and reception channel frequencies for designating the channels of the transmitting unit 14 and the receiving unit 16 under the control of the control unit 11. The voltage detector 17 detects the voltage converted due to the departure of the portable device from the charger and notifies the controller 11 of the departure of the portable device.

Control flow for the line release protection according to an embodiment of the present invention is as shown in FIG.

Referring to FIG. 2, the control process for line release protection according to an embodiment of the present invention will be briefly described. A process of attempting to connect a line when it is detached from a charger, and a line connection is completed when a call key is input. Determining whether the connection has been completed; if the line connection is not completed, continuing the line connection; if determining that the line connection is completed, determining whether a predetermined time has elapsed; In this case, the process includes continuing the function that was being performed, and releasing the line when a predetermined time elapses.

Hereinafter, the line release protection operation according to an embodiment of the present invention will be described in detail with reference to the above configuration.

The controller 11 detects whether the portable device is separated from the charger by the user in step 210. The deviation detection is performed by detecting the blocking of the charging voltage supplied from the charger by the voltage detector 17 and providing a detection signal.

When the controller 11 detects a departure from the charger through the voltage detector 17, the controller 11 proceeds to step 212 and attempts to connect a line. The line connection is used in the sense of switching to a state where a call is possible by forming a radio channel with a main body constituting a radiotelephone. On the other hand, the attempt to connect the line is an operation in which the control unit 11 controls the frequency synthesizer 17 to vary the frequency in order to find a frequency corresponding to the channel where the call is possible. That is, the line connection refers to an operation of selecting a channel by generating a channel frequency.

In step 214, the controller 11 searches whether there is key data input from the key input unit 12 according to a user's key manipulation during a line connection attempt or a corresponding function.

If the input of the key data is not detected in step 214, the method proceeds to step 224 to determine whether the line connection is completed. If it is determined that the line connection is not completed, the process returns to step 212 and continuously attempts to connect the line.

However, if it is determined in step 224 that the line connection is completed, the controller 11 proceeds to step 226 to perform a corresponding function. In general, the corresponding function will be a call by an incoming or outgoing call. The controller 11 continuously checks key data input in step 214 even while the corresponding function is performed in step 226.

On the other hand, the controller 11 detects the input of the key data in step 214 regardless of the completion of the line connection in step 224 proceeds to step 216. In step 216, the controller 11 determines whether the input key data is key data generated by pressing a call key.

If it is determined in step 216 that it is not a call key, the controller 11 proceeds to step 226 to perform a function corresponding to the input key data.

However, if it is determined that the key data detected in step 214 is key data input by pressing a call key, the controller 11 proceeds to step 218 to determine whether the line connection through the frequency synthesizer 17 is completed. To judge. If the line connection is not completed, the call key retrieved in step 216 is ignored and the process returns to step 212 to continue the line connection. The disregarding the call key prevents the current line connection operation from being terminated by the call key input while the line connection is not completed. That is, in order to protect the call from being blocked due to the unconsciously operated call key.

On the contrary, if it is determined in step 218 that the line connection is completed, the controller 11 proceeds to step 220 and determines whether a predetermined time has elapsed after the line connection is completed. Checking the elapse of the predetermined time is to provide sufficient time for the user to confirm that the line is connected. That is, the predetermined time means an elapsed time set by the user or the producer by determining that the user is a sufficient time required to confirm the line connection after the line connection is completed. On the other hand, in order to check the elapse of the predetermined time should be provided with a timer, in the present invention can be implemented by using a timer that is generally provided in the control unit 11 is not specifically disclosed.

If the predetermined time has not elapsed in step 220, the process returns to step 214 to continuously check key data input.

However, if it is determined in step 220 that the predetermined time has elapsed, the controller 11 releases the line in step 222 in response to the call key found in step 216.

As described above, the present invention has an effect of preventing an error of accidentally releasing a line by rejecting a call key input during a line connection attempt or when a line is connected and entered within a predetermined time in a portable device using an automatic connection method.
