Description

Call Switching Method in Mobile Device of Wireless Terminal with Safety Function

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable device of a wireless terminal having a safe function, and more particularly, to a method of converting a call of a general telephone connected in parallel to a portable device.

The wireless terminal refers to a communication terminal having a fixed device and a portable device and performing a wireless communication by forming a call channel between the fixed device and the portable device. Examples of such wireless terminals include wireless telephones, facsimile apparatuses equipped with wireless telephones, and the like.

When the portable device is mounted in the charging device, the portable device switches to the charging mode to charge the battery, and when a call request occurs, the portable device switches to the hook-off state and sets a channel for performing wireless communication with the fixed device. The call request means that the mobile device is detached from the charging device or the call button is pressed while in the standby state.

Typically, the portable device provides a security function for the convenience and privacy of the user.

The relief function for providing the user's convenience includes the function of generating an alarm sound to inform the user of misuse and releasing the call channel if there is no key authorized until a predetermined time elapses after the channel is formed by the call request. have. In addition, the security function to protect privacy includes a function that does not allow a call without connecting a phone line even when a call request is made from another mobile device other than the call state when another mobile device or a parallel connected general phone is in a call. have.

For this reason, when a call is made using a general telephone connected in parallel, and the user attempts to switch the call to a mobile device, the mobile device is first called using an extension calling function provided in a fixed device, and then the converted call is answered in response to the call. Could be done.

If the user does not use the extension calling function of the fixed device and directly makes a call using the call button of the mobile device, the mobile device does not detect the change of the call and determines the call request for calling the other party. When the time elapses, the safe function is performed. Not only does the call not be made by performing the security function, but also generates an alarm sound and releases the channel when the set time elapses.

That is, in the prior art, the user could not make a call after changing the mobile device from the charging device or pressing the call button while making a call with a general telephone. The conversion method was complicated because the currency had to be converted.

As described above, in the related art, a call switching method is complicated, and when a child or an elderly person responds first by using a general telephone connected in parallel, there is a problem in that appropriate measures cannot be taken.

Accordingly, an object of the present invention for solving the above problems is to provide a method for performing a call mode when a call request occurs before the set time elapses after the ring is received.

2 is a control flowchart for call switching according to an embodiment of the present invention.

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

1 is a diagram illustrating a configuration of a portable device that performs wireless communication with a fixing device according to an embodiment of the present invention.

Referring to FIG. 1, the portable device controller 10 includes a memory that stores a secret code of the portable device and controls the overall operation of the portable device. It also controls the operation of performing a call switch according to the present invention. The keypad 24 includes a call key for requesting a call, keys for setting various functions, and a numeric key for performing a dialing function. In addition, the key data corresponding to the key pressed by the user is output to the portable device controller 10. The RF transmitter 12 is a modulation frequency corresponding to a channel in which a transmission voice signal output from the voice processor 18 or a control data output from the portable device controller 10 is formed under the control of the portable device controller 10. It modulates as and outputs through the antenna 26. The RF receiver 14 demodulates a signal received through a channel formed through the antenna 16, outputs a received voice signal to the voice processor 18, and outputs control data to the portable device controller 10. The signal processor 16 controls the RF transmitter 12 and the RF receiver 14 at a modulation frequency corresponding to a channel formed by the control data output from the portable device controller 10. The voice processor 18 amplifies the voice signal input from the transmitter 22 and provides the RF signal to the RF transmitter 12 or amplifies the voice signal received from the RF receiver 14 and outputs the received voice signal to the receiver 20. .

2 is a flowchart illustrating a control for call conversion according to an embodiment of the present invention.

2 illustrates a process of storing the received time when ring data is received in a standby state, and performing a call mode according to a call change when a call request occurs before the reception of the ring data ends and a set time elapses. The process is done.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the configuration of the above-described portable device.

The controller 10 detects in step 212 whether ring data is received from the fixed device in the standby state in step 210. The ring data transmitted from the fixing device is received by the RF receiver 14 through the antenna 26, and the RF receiver 14 demodulates the received ring data and provides the demodulated data to the controller 10. If the control unit 10 detects ring data, it generates a ring tone and proceeds to step 214 to temporarily store a reception time at which the ring data is received in an internal buffer. After storing the reception time, the controller 10 detects authorization of a call request in a state where reception of ring data is continuously detected in steps 216 and 218. When the call request is detected in response to the ring data received in step 216, the controller 10 proceeds to step 224 to form a call channel with the fixed device and performs a call according to the detected ring data. However, if the call request does not occur until the reception of the ring data is not detected in step 218, the controller 10 proceeds to step 220.

In step 220, the controller 10 detects a call request generated by the user before the set time elapses in steps 220 and 222. The call request refers to key data that is applied from the keypad 24 by the portable device leaving the charging device or by pressing the call button. The confusion of the set time can be determined by comparing the reception time stored in step 214 with the time when the call request is detected in step 222. As an example of the set time, it may be set to an average value of the time required to perform a call in response to an incoming ring, and the set time may be arbitrarily set in the same manner as a user registers an ordinary alarm time.

If the controller 10 detects a call request before the set time elapses in steps 220 and 222, the controller 10 proceeds to step 224. In step 224, the controller 10 controls the signal processor 16, the RF transmitter 12, and the RF receiver 14 to form a call channel. When the call channel is formed, the controller 10 determines that the call is switched from the general telephone and performs a normal call mode. The normal call mode refers to maintaining a call state without releasing a channel or performing a security function that generates an alarm sound even after a certain time elapses. In addition, the call state refers to a state in which the fixed device maintains the state of the telephone line and a channel is formed between the portable device and the fixed device so that the call can be made through the portable device.

However, if it is determined in step 220 that the set time has elapsed from the time when the ring data is received, the controller 10 proceeds to step 226. If the control unit 10 proceeds to step 226 to service the conventional security function.

As an example, the security function is described. If it is determined that a call request has occurred after a set time elapses, it detects whether a specific key is pressed before a predetermined time elapses. The predetermined time means a time set to release the channel when the channel is formed due to malfunction of the portable device. If key data by pressing a specific key is applied from the keypad 24 before the predetermined time elapses, the call mode is performed as in step 224.

However, when the predetermined time elapses, the channel formed after the alarm sound is released and the state is switched to the standby state.

That is, the operation according to an embodiment of the present invention described above will be briefly described.

First, when a user switches a call before the set time has elapsed while performing a call answering an incoming ring by using a parallel telephone connected to the incoming call,

When the portable device receives the ring data according to the incoming ring, the portable device reads and stores the time of receiving the ring data from the timer provided in the controller 10. When the user presses a call key of the portable device or leaves the charging device while talking on the ring ring using a general telephone, the portable device performs steps 220 and 222 shown in FIG. In step 220 and step 222, the portable device determines whether a call request has occurred before the set time elapses. If it is determined that the set time has not elapsed, the portable device proceeds to step 224 to perform the call mode. The call mode refers to a mode in which a call is continuously performed in a portable device by switching a call made using the general telephone.

Secondly, when a user switches a call after a set time has elapsed while making a call answering an incoming ring by using a parallel telephone connected to the incoming call,

In step 220, if a call request occurs in a state in which a security function is set after the setting time has elapsed, it detects the application of key data according to the pressing of a specific key within a predetermined time. If the key data is sensed, normal call state is established even if the security function is set.

As described above, the present invention can convert a call being performed through a general telephone connected in parallel to a simple operation of the portable device, thereby providing convenience to a user using the portable device. In addition, it is possible to switch the call in progress through a parallel telephone connected to solve the problem that the call is disconnected when switching the call.
