Description

Method for connecting call in communication terminal {CALL CONNECTION METHOD IN TELEPHONE SET}

The present invention relates to a method for connecting a call in a communication system, and more particularly to a method for actively connecting a received call.

Typically, a call (hereinafter referred to as a 'call' or a 'call') received in a communication system to receive a call by switching to a specific phone number is referred to as call forwarding (hereinafter referred to as 'call forwarding'). And when a call is received, the user enters a phone number to be received and converts the call to a phone number input from the network. This is called Call Deflection.

In other words, the call forwarding function does not receive a call for a certain period of time when the terminal needs to automatically switch a call when receiving a call (when the receiving party cannot answer the call or when the call is outside the coverage area). When, etc.) is to switch the call to the preset phone number. However, the call forwarding has a problem that only one number is always switched regardless of the information of the received call.

The call deflection function is a supplementary service function in a global system for mobile (GSM) system. When the received call is received, the call deflection function informs the user as a subscriber of the call. The user then sees the received telephone number (which allows the calling party's telephone number to be detected by the CLIP) and enters the desired telephone number directly by the receiver to convert the call to the input telephone number. Therefore, the above-described call deflection function has an inconvenient problem of directly inputting a telephone number to be switched each time a call is received.

It is therefore an object of the present invention to provide a method for actively switching a call by received call information.

In order to achieve the above object, the present invention provides a method for connecting a call received at a wireless terminal, the method comprising: checking whether call deflection is set when a call is received, and if the call deflection is set, whether automatic switching is set. Checking the caller, detecting the caller's telephone number from the received call information, checking whether the caller's telephone number is in a pre-stored reference list, if the automatic switching is set, and sending the caller to the reference list. When there is a phone number of the side is characterized in that the process is made to switch the call to the corresponding phone number.

2 is a control flowchart for connecting a received call to another number 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. Specific details appear in the following description, which is provided to aid a more general understanding of the present invention, and it should be understood by those skilled in the art that the present invention may be practiced without these specific details. It will be self explanatory. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a schematic block diagram of a wireless terminal according to an embodiment of the present invention.

2 is a control flowchart for connecting a received call to another number according to an embodiment of the present invention.

A schematic block configuration of a wireless terminal according to an embodiment of the present invention will be described below with reference to FIG. 1.

The controller 100 controls the overall operation of the wireless terminal and the operation for switching the call according to the embodiment of the present invention. The key input unit 140 includes a plurality of numeric and alphabet keys, a function key (FCN), a storage key (STO), a volume down / up key, a navigation key (up, down, left, and right), and generates key data for the keys. . The memory 120 temporarily stores a predetermined operation program and data generated while performing the operation program. The display unit 130 displays a plurality of information such as data display and operation state input from the key input unit 140. The RF unit 150 performs a demodulation operation by amplifying and filtering a signal transmitted and received through the antenna ANT. The voice processing unit 160 processes and digitizes the voice input to the microphone under the control of the control unit 100, and demodulates the voice data received through the RF unit 150 and outputs the same through the speaker.

Referring to Figures 1 and 2 will be described the operation of the embodiment according to the present invention.

In step 200, the controller 100 checks whether a call message is received through the RF unit 150. When the call message is received, the process proceeds to step 210 to check if call deflection is set. The inspection may be performed by the user reading and reading preset data from the memory 120. Table 1 below shows an example of the setting.

Call deflation Auto Switch o o

If call deflection is set, the process proceeds to step 220; otherwise, the process proceeds to step 290 to perform a normal operation. That is, in step 290, the normal alarm mode is performed and the call is made according to the user's response. In step 220, the controller 100 checks whether automatic switching is set. If automatic switching is set, go to step 230; otherwise, go to step 260.

In step 230, the controller 100 detects caller information from the received call message and checks whether the detected information is in a reference list. The above reference list is for performing call deflection according to the information of the calling party which is received with the user's preset information. For example, the reference list is shown in Table 2 below.

Calling party number name Call Deflation Phone 111-222-3333 999-888-7777 222-333-4444 999-888-7777 333-444-5555 999-888-6666 . . . . . . . . . default . 000-111-2222

That is, if the calling party number is '111-2222-3333', call deflection is performed with '999-888-7777', and if '333-444-5555' is called with '999-888-6666'. Perform.

At this time, the calling party number can be detected through CLIP of the received call message. If the calling party number is received in the reference list, the process proceeds to step 240 to perform a call deflection function of switching a call to the corresponding phone number.

If the calling party number is not in the reference list in step 230, the call is deflected to '000-111-2222' set as a default value.

In step 220, the control unit 100 outputs the call deflection phone number, that is, the reference list through the display unit 130. Thereafter, the control unit 100 proceeds to step 270 to perform a call deflection function of switching a call to a phone number selected by a user input phone number or an output reference list (step 280).

An embodiment of the present invention will be briefly described as follows.

After setting call deflation and auto switching, and storing a reference list for auto switching in advance, if a call is received, call deflection is detected through the reference list by detecting caller information.

By the way, in the embodiment of the present invention, all the operations are performed in the terminal itself, but can be made in the network. For example, when the contents of Table 1 and Table 2 (parameters for automatic switching and call deflection: Table 1) (reference list: Table 2) are transmitted to the network and the service of the automatic call deflection function is requested, Of course, the above-described operation may be performed in a network. Hereinafter, the operation of the network is similar to that of the terminal described above, and a detailed description thereof will be omitted. On the other hand, when the connection operation is performed in the network, the execution time of the call deflection function is shortened and additional operations of the user are reduced.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims below, but also by the equivalents of the claims of the present invention.

As described above, the present invention sets up call deflection and automatic switching, stores a reference list for automatic switching in advance, and detects caller information when the call is received to perform call deflection through the reference list. You can actively transfer calls with your information.
