Description

이동통신단말기 수신감지장치{An apparatus for received sensing of a mobile communication terminal}An apparatus for receiving sensing of a mobile communication terminal

본 발명은 이동통신단말기에 수신되는 착신신호를 신체에 부착시키는 별도의 수신감지기를 통해 수신 감지할 수 있는 이동통신단말기 수신감지장치에 관한 것으로, 특히 이동통신단말기가 진동모드나 또는 신체에 휴대되지 않고 근거리에 떨어진 상태에서도 단말기에 착신되는 페이저신호를 그대로 정확하게 수신하여 감지할 수 있도록 함으로서 공공장소에서의 단말기 착신소음을 줄일 수 있는 이동통신단말기 수신감지장치에 관한 것이다.The present invention relates to a mobile communication terminal reception detecting apparatus capable of detecting the reception through a separate reception sensor for attaching the incoming signal received on the mobile communication terminal to the body, in particular the mobile communication terminal is not carried in the vibration mode or the body The present invention relates to a mobile communication terminal reception detecting apparatus capable of accurately receiving and detecting a pager signal received at a terminal even in a short distance from the terminal, thereby reducing terminal incoming noise in a public place.

잘 알다시피, 이동통신의 눈부신 발달은 국민 1인당 1회선 이상의 이동통신단말기 사용을 보편화시키고 있으며, 점차 인터넷과 연계된 필수 통신수단으로 자리잡고 있는 추세이다.As you know well, the remarkable development of mobile communication is making general use of mobile communication terminals more than one line per person, and it is gradually becoming an essential communication means connected with the Internet.

그런데, 휴대용 통신수단으로 편리하게 사용되고 있는 이동통신단말기는 기술수준의 급격한 발달과는 무관하게 사용예절은 그에 못 미쳐, 공공장소에서의 무분별한 단말기 사용으로 인해 주변 사람은 물론 주변 기기 작동에도 심각한 피해가 유발되고 있는 실정이다.However, regardless of the rapid development of technology, mobile communication terminals that are conveniently used as portable communication means are not good manners, and the use of indiscriminate terminals in public places has serious damages not only to neighbors but also to peripheral devices. It is happening.

이에 따라 병원이나 연구소 또는 항공기나 기타 통신반응에 예민한 시설 및 장소에서는 이동통신단말기의 사용이 점차 제한되고 있으며, 특히 강의중이나 회의중에는 사용자가 스스로 단말기 전원 자체를 OFF시키거나 진동모드로 전환시켜 사용하고 있다.As a result, the use of mobile communication terminals is increasingly restricted in hospitals, research institutes, and facilities and places that are sensitive to aircraft or other communication reactions.In particular, during lectures and meetings, users can turn off the power of the terminal themselves or switch to vibration mode. have.

그러나, 이동통신단말기를 진동모드로 전환시켜 사용할 경우에는 벨모드 사용환경에 비해 수신신호를 제대로 인식하지 못하게 될 뿐만 아니라, 특히 이동통신단말기가 근거리에 떨어진 상태에서는 수신신호를 대부분 놓치기 쉬워 부재상황이 될 수밖에 없는 등의 많은 불편이 있었다.However, when the mobile communication terminal is used in the vibration mode, the received signal is not recognized properly compared to the bell mode environment, and especially when the mobile communication terminal is far away, it is easy to miss most of the received signal. There was a lot of inconvenience, such as to be.

이러한 사정을 감안하여 이동통신단말기와는 별도로 단말기에 수신되는 착신신호를 근거리에서도 감지할 수 있는 이동통신단말기 수신감지장치에 대한 필요에 따라 종래에는 도 4에서 보는 바와같이, 이동통신단말기(120)를 통해 착신된 수신신호가 사용자 신체에 부착시키는 별도의 착신알림수신기(130)나 차량의 원격시동스위치(110)로 전송되면서 자동으로 수신 감지될 수 있도록 하였다.In view of the above circumstances, as shown in FIG. 4, a mobile communication terminal 120 according to a need for a mobile communication terminal reception detecting device capable of detecting an incoming signal received at a terminal separately from a mobile communication terminal even in a short distance, is described in FIG. 4. Received through the received signal is transmitted to a separate call notification receiver 130 or the remote start switch 110 of the vehicle to be attached to the user's body so that it can be automatically received and detected.

즉, 이동통신단말기(120)가 기지국과의 통화모드로 작동할 때 단말기(120)의 신호음이나 신호광 표시가 음압센서(123)나 광센서(124)로 인식되면서, 동시에 별도로 프로그램 내장된 제어회로와 단말기 전원에 의해 새로운 작동주파수(Running Frequency)를 발생시켜 근거리의 착신알림수신기로 전송될 수 있도록 하였다.That is, when the mobile communication terminal 120 operates in the call mode with the base station, a signal sound or signal light indication of the terminal 120 is recognized as the sound pressure sensor 123 or the optical sensor 124, and at the same time, a separate program-controlled circuit The new running frequency is generated by the power supply of the terminal and the terminal so that it can be transmitted to the near call notification receiver.

그러나, 이러한 단말기 수신신호 전송방식은 보안적 측면에서 어느정도 효과는 있지만, 그 제작비용이 높고 실시간 수신 여부를 정확하게 판단하기 곤란하며, 아울러 단말기(120) 제작시에 함께 프로그램 내장되는 제어회로와 각 이동통신사별로 해당 주파수 특성에 맞는 주파수필터를 고려하여 제작되어야 하므로, 단말기 (120)의 부피가 상대적으로 크고 그 제작도 어려운 것은 물론 제어프로그램을 내장시켜야 하는 불편이 있었다.However, although the terminal reception signal transmission method has some effect in terms of security, the production cost is high and it is difficult to accurately determine whether the terminal is received in real time. Since each carrier must be manufactured in consideration of the frequency filter for the corresponding frequency characteristics, the volume of the terminal 120 is relatively large and difficult to manufacture, as well as the inconvenience of having a built-in control program.

아울러, 작동 전원으로 단말기 전원이 사용될 수밖에 없어 결과적으로 배터리수명이 단축되고, 기존의 상용화된 이동통신단말기(120)에 적용하기도 사실상 불가능하다는 등의 문제점이 있었다.In addition, there is a problem that the terminal power to be used as the operating power as a result, the battery life is shortened, it is practically impossible to apply to the existing commercialized mobile communication terminal 120.

따라서, 본 발명은 각 이동통신사별로 해당 주파수 특성에 맞는 작동주파수로써 단말기의 수신신호를 원격 감지하는 기존의 이동통신단말기 수신감지기의 제반 문제점을 해결하면서 상대적으로 단순화된 구성으로도 이동통신단말기에 수신되는 착신신호를 이동통신사별의 주파수 특성에 별다른 제한없이 정확하게 수신 감지할 수 있도록 제안된 것으로, 이동통신단말기가 진동모드나 또는 신체에 휴대되지 않고 근거리에 떨어진 상태에서도 단말기에 착신되는 페이저신호를 그대로 정확하게 수신하여 감지할 수 있도록 하여 공공장소에서의 착신음 소음을 줄이면서 단말기 수신신호 감지서비스를 만족시킬 수 있는 이동통신단말기 수신감지장치를 제공함에 그 목적이 있다.Accordingly, the present invention solves all the problems of the conventional mobile communication terminal reception detector that remotely detects the reception signal of the terminal as an operating frequency corresponding to the frequency characteristic of each mobile communication company, and receives the mobile communication terminal with a relatively simplified configuration. It is proposed to accurately receive and receive incoming signals without any limitations on the frequency characteristics of each mobile carrier, and it is possible to keep the pager signal received at the terminal even when the mobile communication terminal is not moved by the body or in a short distance. It is an object of the present invention to provide a mobile communication terminal reception detection device that can satisfy the terminal reception signal detection service while reducing the ring tone noise in public places by enabling accurate reception and detection.

도 1은 본 발명에 따라 이동통신기지국(10)과 이동통신단말기(20)의 통화모드 변화시에 처음 발생하는 페이저신호에 대한 작동개념을 도시한 것으로, 위치정보를 알려주는 미약한 파이럿신호(Pilot Signal)에 비해 페이저신호(Phasor Signal)는 통화모드에서 동작하는 신호레벨과 흡사한 대역크기를 갖기 때문에 정확한 신호감지가 용이하다.1 is a view illustrating an operation concept of a pager signal first generated when a call mode is changed between a mobile communication base station 10 and a mobile communication terminal 20 according to the present invention. Compared to the pilot signal, the phaser signal has a band size similar to that of the signal level operating in the call mode, and thus it is easy to accurately detect the signal.

아울러, 도 2는 본 발명에 따라 별도의 작동주파수를 갖지 않는 이동통신단말기 수신감지장치의 내부 구성회로를 도시한 것으로, 각 이동통신사별 주파수특성에 대응되는 해당 주파수신호를 통과시키는 주파수필터(33)를 통해 가장 인접한 인근 이동통신사간의 주파수대역으로 5㏈ 이상의 주파수신호를 가질 수 있고, 증폭기 (34)를 통과하여 전압조정기(Voltage Regulator)(39)를 동작시키는 전체적인 작동개념을 회로구성으로 나타내고 있다.In addition, Figure 2 shows the internal configuration circuit of the mobile communication terminal receiving detection apparatus does not have a separate operating frequency in accordance with the present invention, the frequency filter for passing the corresponding frequency signal corresponding to the frequency characteristics of each mobile carrier (33) It can have a frequency signal of 5 kHz or more as the frequency band between the adjacent neighboring mobile carriers through the), and the overall operating concept of operating the voltage regulator (39) through the amplifier 34 is shown in a circuit configuration .

도면에서 보는 바와같이, 본 발명의 이동통신단말기 수신감지장치는 도 3의 국내 이동통신사들의 단말기주파수 대역특성에 대응되는 작동주파수를 갖지 않고 이동통신기지국(10)과의 통화모드 동작시에 발생되는 강한 페이저신호(주파수신호)를 그대로 정확하게 수신받아 감지할 수 있도록 구성된다.As shown in the figure, the mobile communication terminal reception detecting apparatus of the present invention does not have an operating frequency corresponding to the terminal frequency band characteristics of the domestic mobile communication companies of FIG. 3 and is generated in a call mode operation with the mobile communication base station 10. It is configured to receive and detect a strong phaser signal (frequency signal) as it is.

즉, 이동통신기지국(10)의 송신안테나(12)를 통해 이동통신단말기(20)의 수신안테나(22)로 수신되는 착신신호를 페이저신호로서 단말기(20)와는 별도로 근거리에서 착신받을 수 있도록 신체에 부착시키는 수신감지기(30)는, 이동통신기지국과(10)의 통화모드 동작시 발생하는 이동통신단말기(20)의 페이저신호를 수신할 수 있도록 각 이동통신사의 고유주파수를 공진주파수로 설정한 감지안테나(32)와, 상기 감지안테나(32)를 통해 수신 추출되는 반사계수 파라미터를 해당 이동통신사 주파수특성에 합당되도록 주파수신호를 통과시키는 주파수필터(33)로 구성된다.That is, an incoming signal received by the receiving antenna 22 of the mobile communication terminal 20 through the transmitting antenna 12 of the mobile communication base station 10 may be received as a pager signal separately from the terminal 20 at a short distance.

The resonance parameter of the frequency filter 33 is extracted by driving an electromagnetic simulator in order to connect the reflection coefficient parameter extracted through the coefficient extraction step with the frequency filter 33 that passes the corresponding frequency signal so as to correspond to the frequency characteristics of each mobile communication company. The resonance parameter extraction step is performed.

그리고 공진파라미터 추출단계의 판단 결과, 통과되는 주파수신호가 소정의 기준치에 도달되면 해당 주파수신호를 입력받아 증폭기(34)를 통해 증폭작용이 이루어지는 주파수신호 증폭단계를 거치게 된다.As a result of the determination of the resonance parameter extraction step, when the passing frequency signal reaches a predetermined reference value, the corresponding frequency signal is input and undergoes a frequency signal amplification step in which an amplification operation is performed through the amplifier 34.

아울러 주파수신호 증폭단계의 판단 결과, 증폭기(34)를 통해 증폭 출력되는 주파수신호가 소정의 기준치에 도달하면 발광기(35)와 진동기(37)가 자동 동작되면서 이동통신단말기(20)의 수신상태를 감지되는 수신감지 작동단계를 거치게 되며, 이때 발광기(35)와 진동기(37)는 해당 전환스위치(36)를 통해 선택 설정되어 출력전압을 유지하는 전압조정기(39) 및 배터리(38)에 의해 자동 작동될 수 있다.As a result of the frequency signal amplification step, when the frequency signal amplified and output through the amplifier 34 reaches a predetermined reference value, the light emitter 35 and the vibrator 37 are automatically operated to receive the reception state of the mobile communication terminal 20. Receiving operation of the sensing step is performed, the light emitter 35 and the vibrator 37 is selected and set through the corresponding switching switch 36 automatically by the voltage regulator 39 and the battery 38 to maintain the output voltage Can work.

It is convenient to use and the size of the device itself can be reduced, and manufacturing cost can be reduced.As a result, it can solve the absence situation due to the short distance environment of the user of the mobile communication terminal and solve the ringing noise problem in public places. It is expected to be.

특히, 국내 이동통신서비스의 단말기 송신주파수가 각각 다른 점을 이용하여 안테나의 공진주파수를 설정하고 고유의 대역폭에서만 작동할 수 있는 주파수필터를 사용하도록 설계함으로서, 이동통신사간의 주파수간섭이 제거되어 사용자의 해당 이동통신서비스에만 동작하게 할 수 있는 효과를 얻을 수 있다.In particular, by setting the resonance frequency of the antenna by using the point that the terminal transmission frequency of domestic mobile communication service is different and using the frequency filter which can operate only in the unique bandwidth, the frequency interference between mobile carriers is eliminated.
