On the other hand, with the recent increase in the spread of portable wireless terminals and the exposure of personal privacy information, telephone crimes (eg, stalking, intimidation and fraud) have increased.

Conventionally, when a threatening call (or an emergency call) is received by a portable wireless terminal, the user generally ends the call and then calls the police station to report a criminal act (or emergency). . The police department then tracks the abuser's location using the call log with the abuser (or the person in need). Such post-processing method has a problem that it is possible to secure evidence to prove the criminal act early or lose the opportunity to arrest the offender early.

If a criminal act (or emergency) can be reported during a more active call, the offender (or the person in emergency) will be tracked in real time.

Accordingly, an object of the present invention is to provide an apparatus and method for reporting an emergency situation (or criminal activity) in real time during a call in a portable wireless terminal.

Referring to FIG. 1, the portable wireless terminal 10 stores voice data of a counterpart received in an memory when an emergency key input is detected during a call, and transmits the stored voice data to a network to notify an emergency situation. do. In this case, the portable wireless terminal 10 may block the user's voice as an example and transmit voice data of the other party to the network through a currently open call channel (or reverse traffic channel). As another example, a new communication channel (or reverse traffic channel) may be opened through a known three-way communication method, and voice data of the other party may be transmitted through the opened communication channel. At this time, an identifier indicating the emergency situation and the other party's telephone number are also transmitted, so that the network can cope with the emergency situation.

The base station 31 transmits the voice data of the counterpart received from the terminal 10 to the control station 32, and the control station 32 transfers the voice data of the counterpart to the switching station 33. The switching center 33 tracks the location using the phone number of the other party who is talking to the terminal 10. At this time, if necessary, using the other network (PSTN, Internet, private network) to track the location of the other party. The switching center 33 generates an emergency message including the tracked location information and the voice data of the counterpart, and converts the emergency message into a signal format of a corresponding transmission path (network 40). Transfer to 50.

The SOS organization 50 analyzes the emergency message received from the mobile communication network 30, displays the information on the monitor, and stores and reproduces the voice data. In this case, the displayed content may be a phone number and a current location of the counterpart. In this way, since the location and call details of the criminal (or the person in emergency) are reported to the SOS organization 50 in real time, the emergency situation can be dealt with more quickly.

In the following description, the portable radio terminal includes a cellular phone, a personal communication system (PCS), a personal data assistant (PDA), an international mobile communication-2000 (IMT2000) terminal, and 4G ( It is meant to include all OFDM (orthogonal frequency division multiplexing) terminals and the like, and the following description will be given with the general configuration of the above examples.

Referring to FIG. 2, a controller (MPU: Micro-processor unit) 200 controls the overall operation of the terminal. For example, it performs processing and control for voice call and data communication, and processes the function for transmitting the voice data of the other party received at the time of emergency key input during the call to the network in addition to the normal function. . Therefore, in the following description, description about the process and control of the normal control part 200 is abbreviate | omitted.

The memory includes a program memory 202, a data memory 204, a nonvolatile memory 206, and the like. The program memory 202 stores a program for controlling the overall operation of the terminal. The program memory may use a flash memory. The data memory 204 temporarily stores data generated during the operation of the terminal. The data memory may use random access memory (RAM). The nonvolatile memory 206 stores system parameters and other storage data (telephone number, message, image data, etc.). The nonvolatile memory may use an EEPROM. The voice data of the counterpart stored when the emergency key is input according to the present invention may be stored in the flash memory or the RAM.

Key pad 208 includes numeric keys 0-9, menu key, cancel key (clear), confirmation key, call key (TALK), end key (END), internet access key, navigation keys. And a plurality of function keys and provide key input data corresponding to a key pressed by the user to the controller 200. The display unit 210 displays status information (or indicators) generated during operation of the terminal, limited numbers and characters, moving pictures, still pictures, and the like. The display unit 110 may use a color liquid crystal display (LCD).

An audio codec (Coder-Decoder) 212 connected to the control unit 200, a speaker 216 and a microphone 214 connected to the codec 212 are voice input / output blocks used for a voice call.

For example, in the case of transmission, channel coding and spreading of data to be transmitted are performed, and in the case of reception, despreading and channel decoding of a received signal are performed. .

Next, a detailed operation based on the configuration of FIGS. 1 and 2 described above will be described.

3 shows a procedure for reporting an emergency situation during a call in a portable wireless terminal according to the first embodiment of the present invention.

Referring to FIG. 3, first, the controller 200 performs a call mode in step 301. During the call mode, the controller 200 checks whether an emergency key is input by the user in step 303. Here, the emergency key may be implemented as one of existing keys, or may be implemented as a dedicated key that can be used only as an emergency key.

When the emergency key is input, the controller 200 proceeds to step 305 and stores the received voice data of the other party in a predetermined area in the memory. In operation 307, the controller 200 mutes the voice of the user input to the microphone.

After the voice of the user is blocked, the controller 200 transmits the stored voice data of the counterpart to the network through a currently open call channel (or reverse traffic channel) in step 309. The voice data may be any one of pulse code modulation (PCM), adaptive multi ratio (AMR), and advanced audio codec (AAC) data.

In this way, the received voice data of the other party is stored in real time and transmitted to the network. At this time, an identifier indicating an emergency is also transmitted to cope with an emergency in the network. In this case, since the call channel is used as a channel for notifying an emergency, the voice of the other party cannot be transmitted.

While transmitting the voice data of the other party to the network, the controller 200 checks whether an emergency release key is input in step 311. When the emergency situation release key is input, the control unit 200 proceeds to step 313 to release the voice blocking of the user and transmits the user's voice to the counterpart normally.

In a state in which the user's voice is normally transmitted to the other party, the controller 200 checks whether a call termination is detected in step 315. If the end of the call is not detected, the control unit 200 returns to step 303 to perform the following steps again. In this way, the user's voice or the other party's voice can be selectively transmitted through the call channel currently opened by the user's key operation during the call. On the other hand, if the end of the call is detected, the controller 200 proceeds to step 317 to end the call mode.

4 illustrates a procedure for reporting an emergency situation during a call in a portable wireless terminal according to a second embodiment of the present invention.

Referring to FIG. 4, first, the controller 200 performs a call mode in step 401. During the call mode, the controller 200 checks whether an emergency key is input by the user in step 403. Here, the emergency key may be implemented as one of existing keys, or may be implemented as a dedicated key that can be used only as an emergency key.

When the emergency key is input, the controller 200 proceeds to step 405 and stores the received voice data of the counterpart in a predetermined area in the memory. At the same time, the control unit 200 proceeds to step 407 to open one more communication channel (or reverse traffic channel) in a three way communication method.

In operation 409, the controller 200 transmits the stored voice data of the other party to the network through the opened new communication channel (or reverse traffic channel). The voice data may be any one of pulse code modulation (PCM), adaptive multi ratio (AMR), and advanced audio codec (AAC) data. In this way, the received voice data of the other party is stored in real time and transmitted to the network. At this time, an identifier indicating an emergency is also transmitted to cope with an emergency in the network.

While transmitting the voice data of the counterpart to the network, the controller 200 checks whether a call termination is detected in step 411. If the end of the call is detected, the controller 200 proceeds to step 413 to end the call mode.

The second embodiment of the present invention described above is a method of opening one reverse communication channel using a three-way communication method and transmitting voice data of the other party to the opened reverse communication channel. In this case, since the emergency can be notified through a separate channel while normally making a call with the other party, the other party can report the emergency situation without noticing.

Meanwhile, embodiments of the present invention propose a method of storing the other party's voice in real time and transmitting the same to the network.

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 determined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

As described above, the present invention can more actively cope with crimes (or emergencies) using the telephone by securing the evidence of telephone crimes and tracking and reporting the location of the abuser (or the person in an emergency situation) in real time. There is an advantage to this. In addition, since the recorded data of the actual situation is transmitted to the police or paramedics, there is an advantage of preventing the loss caused by mischief calls and reducing the loss of manpower and resources.
