Abstract

PURPOSE: A call connection informing apparatus and method of a communication terminal are provided to remove user's inconvenience of continuously holding a terminal to his/her ear until a callee answers after the user makes a call. CONSTITUTION: An MPU(Micro-Processor Unit) checks whether a phone number is inputted and an originating key(or a call key) is inputted(201). If the MPU detects inputting of the call key, it generates an originating message to start a call and transmits it to a BTS(Base Transceiver System)(203). The MPU checks whether the line is busy(205). If the line is not busy, the MPU receives a ring back tone from a system and transfers it through a transmitter(207). The MPU checks whether a speech path is connected as a callee answers or through a voice mail box(209). When the speech path connection is detected, the MPU transfers a buzzer sound through the transmitter to inform the user of the speech path connection(211). The MPU enters into a call mode(213) and checks whether a call termination key is inputted(215).

Referring to FIG. 1, a control unit (MPU: Micro-processor unit) 100 controls the overall operation of the communication terminal. For example, it performs processing and control for voice call and data communication, and processes a function to detect a call connection after the call according to the present invention and inform the user with a buzzer (or vibration) in addition to the normal function. Therefore, in the following description, description about the process and control of the normal control part 100 is abbreviate | omitted.

The read only memory (ROM) 102 stores microcode and various reference data of a program for processing and controlling the control unit 100. In particular, according to the present invention stores a program for detecting the call connection after the call to inform the user to the buzzer (or vibration or lamp). Random Access Memory (RAM) 104 is a working memory of the controller 100. Stores temporary data generated during the execution of various programs. Flash RAM 106 stores various updatable storage data such as a phone book.

Key pad 108 includes numeric keys 0-9, menu, call (TALK), clear (CLR), end (END), *, #, scroll keys (UP / DOWN keys), etc. A plurality of function keys are provided, and key input data corresponding to a key pressed by the user is provided to the controller 100. The display 110 displays status information generated during the operation of the wireless telephone, a limited number of characters, a large amount of video and still images, and the like. The display unit 100 may use a liquid crystal display (LCD).

The codec (Coder-Decoder) 112 connected to the control unit 100, and the transmitter and receiver 116 and the receiver 114 connected to the codec 112 are voice input / output blocks used for phone calls and voice recording. to be. The codec 112 converts the PCM data provided from the control unit 100 into an analog voice signal, transmits the same through the talker 116, and converts the voice signal received through the receiver 114 into PCM data. To the control unit 100. The motor driving unit 118 notifies the user of the lake god by vibrating by driving the motor when the call is received under the vibration mode.

In addition, the RF unit (Radio Frequency unit) (120) is the frequency of the radio frequency signal received via the antenna to the baseband processing unit 122 by lowering the frequency, the baseband signal from the baseband processing unit 122 to increase the frequency Transmit through the antenna. The baseband processor 122 processes the baseband signal transmitted and received between the RF unit 120 and the controller 100. For example, in case of transmission, channel coding and spreading of data to be transmitted are performed, and in case of reception, despreading and channel decoding of a received signal are performed. .

Hereinafter, a detailed operation according to the present invention will be described with reference to FIG.

FIG. 2 illustrates a control procedure for automatically detecting a call connection after an outgoing call in a communication terminal according to an embodiment of the present invention and informing a user with a buzzer (or vibration or lamp).

Referring to FIG. 2, the control unit 100 checks whether a telephone number is input and a calling key (or call key) is input in step 201. If the input of the calling key is detected, the control unit 100 proceeds to step 203 to generate an outgoing message for initiating a call and transmits it to the base station (BTS), otherwise proceeds to step 217 to perform the corresponding function. do.

After transmitting the outgoing message, the controller 100 checks whether the other party is busy in step 205. In other words, it checks if a busy tone is received from the system. If the busy signal is received, the communication terminal proceeds to step 211, otherwise proceeds to step 207 to receive a ring back tone from the system and transmit it through the transmitter 116. In this case, if the "call connection notification mode" according to the present invention is set in the terminal, the ring back tone may not be transmitted through the transmitter 116 because the user has a high probability of not holding the terminal to the ear.

During the ringback tone reception, the controller 100 checks whether the other party is connected to a response or voicemail in step 209 to connect a call (or call). The call path is connected by assigning a traffic channel by a response message received from the base station. Therefore, the control unit 100 detects the connection as a call by checking whether or not the call is received.

If the connection is not detected by the call, the control unit 100 returns to step 207 to continuously receive a ringback tone, and if the connection is detected by the call, proceed to step 211 to notify the user of the connection by call. The buzzer sounds through the transmitter 116. As another example, the motor driving unit 118 to provide a vibration or to drive a lamp (not shown) provided on the outside of the terminal. At this time, the user checks the state (buzzer sound, vibration, lamp light) of the terminal as described above to recognize that the other party has responded. On the other hand, step 211 is also performed when it is detected that the call in step 205. That is, when it detects a call, it informs the user to a buzzer (or vibration or lamp) as described above.

Thereafter, the controller 100 enters the call mode in step 213 and checks whether a call termination key is input in step 215. If the call termination key is input, the controller 100 immediately terminates the program according to the present invention. Otherwise, the controller 100 returns to step 213 to continue the call mode. That is, the present invention enables the terminal to make a call by buzzer or vibration by recognizing this when the other party answers or when connected to the voice mailbox when making a call.

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. In the above embodiment, it has been described that the call connection notification mode according to the present invention is performed without setting a mode, but only when the call connection notification mode is set by the user and the call connection notification mode is set. You can also perform the operation according to. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention can eliminate the inconvenience that the user must hold the terminal to the ear until the other party responds after the call. In addition, there is an advantage that the user can immediately recognize that the other party is busy even if the user immediately puts down the terminal after the call by notifying the user even during a call.
