Abstract

The answering method comprises the following steps: sampling the value corresponding to the key input by serching the buffer, which stores the value relevant to the key input; discriminating whether the sampled value corresponeds to the power source on/off key (PWR) or not; executing the power source off routine in the case of PWR, otherwise proceeding to the next step; jumping the key processing routine if the wait-for-answer task is not; clearing the buffer in the case of wait-for-answer tasking; executing the key processing routine for transmission. This method is useful for cellular mobile telephone as well as for hand phone.

Description

How to answer a call on a car telephone

1 is an exemplary view showing a handset key arrangement of an automobile telephone.

2 is a flowchart illustrating a method for answering an incoming call of an automobile telephone according to the present invention.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a user interface that can more conveniently use an automobile telephone in a cellular mobile telephone. In particular, the present invention relates to a hand that is not a "send key" when an incoming call rings. The present invention relates to a call answering method that allows a user to answer a call by pressing any key on the handset.

Automobile telephones are mainly used in the car, and are used in two types: an outgoing call in which a user makes a call and an incoming call in which a call is received from the other party.

Therefore, in the case of an outgoing call, the user can select a convenient and safe point and place, that is, the call can be made in a safe state when driving slowly or at a stop, but in the case of an incoming call, a call can be made even while driving or in a dark place. . In this case, there is a problem that can cause a dangerous accident, such as a traffic accident while driving, because you have to answer the phone by picking up the receiver.

In order to solve the above problems, an automobile telephone with a "hand free" function capable of making a call without picking up a handset has been devised and widely used. However, in order to make a call using the hand free method, when the bell rings, the user needs to press the "Send Key" on the handset. It is very difficult to create a risk of traffic accidents and there is a problem that the quick response is difficult.

The present invention devised to solve the above problems, in an automobile telephone, in the case of a ringing incoming call, pressing any key except for the power on / off key on the handset, rather than looking for the "transmission key". The object of the present invention is to provide a call answering method that enables a quick and safe call even when a car is ringing in a dark place while driving or in a dark place.

In order to achieve the above object, the present invention can answer a call by pressing all other function keys except the power on / off key (PWR) on the handset in response to the call from the other party in the portable telephone or the automobile telephone. A method of answering a call, comprising: a first step of sampling a value corresponding to a pressed key by searching a buffer storing a corresponding key value according to a key press; and wherein the sampled key value is a power on / off key. If the power on / off key is determined to be the power on / off key, if not the power on / off key, the second step to proceed to the next step, and after performing the second step of the current operation performed by checking the response, Jumps to the key processing routine corresponding to the original key if it is not in a wait-for-answer task, and clears the above key value storing buffer (c during the waiting for response). and a third step of allowing the pressed key to be referred to as a transmission key so as to make a call with the other party by performing a transmission key (SND) processing routine.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

FIG. 1 is a diagram illustrating an arrangement of a handset key of an automobile telephone, and FIG. 2 is a flowchart illustrating a method for answering an incoming call of an automobile telephone according to the present invention.

When an automobile telephone with a handheld key arrangement as shown in FIG. 1 is ringing by a call from the other party, the system program performs a wait-for-answer task. At this time, pressing the "SND" key of FIG. However, in the present invention, when any call is pressed except for the "PWR" key, which is a power on / off key, the present invention does not perform the original function of the key but the transmit key (SND) is pressed. Assume that you can talk to the other party. The power on / off key (PWR) is excluded from the transmit key in the call response because the power on / off key (PWR) is hardware-configured, and when the system is on, pressing the key turns off the system. Because it becomes.

The above description will be described with reference to FIG. 2.

When the car phone is on, it performs call processing (from the time the phone is powered up, to call calls, incoming calls, and other functions), which keys on the handset are pressed at regular intervals. Retrieve the key value. In this case, if a key is pressed, a value (hexadecimal value) corresponding to the key is stored in a buffer (100), and the key value is searched to determine whether the key value corresponds to a power on / off key (PWR) (110). If it corresponds to the power on / off key (PWR), it jumps to the routine for turning off the power (120).

If it does not correspond to the power on / off key (PWR), it checks the current task (130), and if it is in a wait-for-answer task, that is, a call is received from the other party. In order to retrieve a key that is subsequently pressed, the buffer in which the currently pressed key value is stored is cleared (150), and the transmission key (SND) is assumed to be pressed and jumped to the transmission key (SND) processing routine (160). If the other party is not in a wait-for-answer task, the user jumps to the processing routine corresponding to the original key (140). For example, when the number key is pressed, the number corresponding to the key is displayed on the display window, and when the clear key is pressed, the number displayed on the display window is deleted one by one from the last inputted value, and the storage key (STO) is pressed. Alternatively, when the recall key (RCL) is pressed, the phone number is stored in the memory or the phone number stored in the memory is displayed on the display window.

The present invention configured and operated as described above has an effect of making a safe and quick response to an incoming call when driving or in a dark place, and is applicable to a mobile phone as well as a mobile phone.

Claims (1)

A method for answering a call in which a portable telephone or a mobile telephone can answer a call by pressing any other function key except for a power on / off key (PWR) on a handset in response to a call from the other party. A first step (100) of sampling a value corresponding to a pressed key by searching a buffer storing a corresponding key value according to a key press, and determining whether the sampled key value corresponds to a power on / off key (PWR) If it is the on / off key, it performs the power-off routine and proceeds to the next step if it is not the power on / off key, and checks the current performing work after performing the second step (130). If it is not during the Wait-for-answer Task, it jumps to the key processing routine corresponding to the original key (140), and if the response is waiting for a response, the key value storage buffer is cleared (150).Known key By performing a send key (SND) key handling routine by considering the transmission 160, the received call (Call) response method comprising including a third step to answer the call.
