Mobile terminal for automatically setting ringing mode and vibration mode according to light and temperature detection result and method thereof {Mobile Terminal for Automatically Setting Bell Mode and Vibration Mode by Sensing Light and Temperature and Method Therefor}

The present invention relates to a method and a mobile communication terminal for automatically converting a mobile communication terminal between a vibration and a ringing mode in response to a sensing unit. More specifically, when a call is received in a mobile communication service system, a light detecting unit and a temperature detecting unit are mounted on an existing mobile communication terminal to automatically switch to a ringing mode and a vibration mode according to light and temperature recognized by the two detecting units. It relates to a mobile communication terminal.

1 illustrates a configuration of a typical mobile communication service system.

The mobile communication service includes a sender's mobile communication terminal 110, a sender's wireless base station 120, a mobile communication switching station 130, a visitor location register (VLR) 132, a home. A home location register (HLR) 134, a receiver side wireless base station 140, a receiver's mobile communication terminal 150, and the like.

When the sender makes a call to the receiver via the mobile communication terminal 110, the transmission signal is first transmitted to the wireless base station 120 on the sender side. The wireless base station 120 includes a base station transmission system (BTS) 122, a base station controller (BSC) 124, a repeater (Cell Enhancer) (not shown), and the like.

Here, the base station transmitter 122 is arranged in units of cells, and transmits a call request generated from the mobile communication terminal 110 to the mobile communication switching center 130, or moves in a cell area under its control. Location registration to determine the location of the communication terminal 110 is performed. The base station transmitter 122 may obtain information such as latitude and longitude at which the base station transmitter 122 is located from a global positioning system (GPS) (not shown), and the position information of the base station transmitter 122 may be obtained from the forward link call channel. The system parameter message is transmitted to the mobile communication terminal 110. The mobile communication terminal 110 may register new location information by calculating the moving distance of the mobile communication terminal 110 by using the location information of the base station transmitter 122 of the cell to which the mobile communication terminal 110 belongs.

Location registration is a procedure in which the base station transmitter 122 communicates the location, status, identifier, slot period, and other features of the mobile communication terminal 110 to the mobile communication switching center 130 through the base station transmitter 122. This is a procedure for effectively calling the mobile communication terminal 110 when the incoming call is to be set to the terminal 110. The location registration of the mobile communication terminal 110 is performed when the mobile communication terminal 110 is turned on and off, when the mobile communication terminal 110 moves between the mobile communication switching stations 130, and the mobile communication terminal ( If the parameter of 110) is changed.

The base station controller 124 performs various functions necessary for radio call processing such as handoff while controlling and managing a plurality of base stations. The base station controller 114 also transmits the subscriber information of the location registered mobile communication terminal 110 to the mobile communication switching center 130.

The mobile communication switching center 130 has a control function for allowing the wireless base station 120 to operate efficiently and an interworking function with an exchange of a public telephone network. When the mobile communication switching station 130 registers the location of the mobile communication terminal 110 through the wireless base station 120, the mobile communication switching station 130 transmits subscriber information of the mobile communication terminal 110 to the VLR 132 in the mobile communication switching station 130. After the temporary storage, the HLR 134 requests the location registration of the mobile communication terminal.

Here, the HLR 134 is a database that stores a service profile about subscriber information of the user of the mobile communication terminal 110. The HLR 134 includes a mobile identification terminal of the mobile communication terminal 110 including a subscriber's telephone number. It contains information about MIN, Electronic Serial Number (ESN), and service type. The HLR 134 stores a subscriber information including information of the wireless base station 120 and the mobile communication switching station 130 where the mobile communication terminal 110 is located. The mobile communication switching center 130 is composed of a control unit, a call path unit and a peripheral device, and also has a charging data collection function for the mobile communication terminal 110.

When the mobile communication exchange station 130 collects information on the sender side in this way, it transmits a signal to the wireless base station 140 having the receiver side, and the wireless base station 140 again transmits the base station controller 144 and the base station repeater 142. Through the signal to the receiver's mobile communication terminal 150 again. The call is made through this process is a mobile communication service system.

When a call is made from the sender to the receiver through such a mobile communication system, the current mobile communication terminal has functions such as a ringtone mode, a vibration mode, and a vibration ringtone mode as a method for notifying the receiver. In public places such as meetings, lectures, theaters, performance halls, buses and subways, the vibration mode is recommended to prevent the disturbance of the atmosphere and for the convenience of others.However, at present, the vibration mode is manually switched from the ring mode to the vibration mode. Because you have to do this, you often forget to ring in these public places.

2 is a block diagram schematically illustrating a configuration of a receiver of a conventional mobile communication terminal.

The conventional mobile communication terminal 150 includes a key input unit 202, a liquid crystal display unit 204, a mode state storage unit 206, a microprocessor 208, a mobile phone vibration unit 210, a speaker 212, a microphone 214 And a base band converter 216, a digital signal processor 218, an RF signal processor 220, an antenna 222, and the like.

The key input unit 202 includes a numeric key for inputting a number such as a telephone number and a menu selection button for switching between vibration and ringing modes. It also has a special key that allows you to switch ringtones and vibrations with just one touch. When the key input unit 202 is switched to the ringing mode or the vibration mode, the liquid crystal display unit 204 displays this state. The mode state storage unit 206 stores the operation mode of the mobile communication terminal selected by the key input unit 202 as a state flag.

The liquid crystal display unit 204 is a part for informing the user by displaying the current state of the mobile communication terminal so that the user can perform appropriate control. The LCD screen displays various information such as power supply status, radio wave reception strength, date and time, current mode status, and other user information. By transmitting this information to the user, the user can check and control the state of the current mobile communication terminal.

The mode state storage unit 206 stores and maintains the state when the key input unit 202 is switched between the ring mode and the vibration mode by a user of the mobile communication terminal. When the call signal is received, the stored communication mode is notified to the microprocessor 208 so that the mobile communication terminal operates.

The microprocessor 208 is the most essential part of the mobile communication terminal, and controls all operations of the mobile communication terminal to be performed properly. The microprocessor 208 controls the operation of the mobile communication terminal with reference to the state flag stored in the mode state storage unit 206 during the mode state operation. In particular, when the ring mode is set in the mode state storage unit 206 by the key input unit 202, a call request signal input from the antenna 222 to the RF signal processor 220 is input to the microprocessor 208. When transmitted, the speaker 212 is operated, and if the vibration mode is set in the mode state storage unit 206, the mobile phone vibration unit 210 is operated. When the operating signal is transmitted from the microprocessor 208, the mobile phone vibration unit 210 causes the mobile communication terminal to vibrate using a motor.

The baseband converter 216 converts signals transmitted and received between the RF signal processor 220 and the digital signal processor 218, the speaker 212, and the microphone 214 into baseband signals, and converts them into digital-analog signals. Performing a function such as conversion and analog-to-digital conversion processing, and the speaker 212 outputs a voice signal output from the baseband conversion unit 216 or a ring tone stored in the microprocessor 208 as an audible sound. 214 converts the user's voice input into an electrical signal.

The digital signal processor 218 has a digital signal processing processor that codes or decodes a voice signal, performs an equalization function to remove multipath noise, and performs an acoustic data processing function. In addition, the digital signal processor 218 exchanges voice data SPEECH with the baseband converter 216 and receives digital data RX DATA from the baseband converter 216.

The RF signal processor 220 demodulates and amplifies the RF signal received by the antenna 222, and modulates and transmits the transmitted signal applied from the baseband converter 216.

In the conventional mode switching method of the mobile terminal, the mode is switched only by the operation of the key input unit 202. When the ring mode is normally set, the operation of the key input unit 202 in the vibration mode is performed. When not in use, there may be a situation where the ringer rings at any time and place. Therefore, there is a demand for a technology that prevents ringing at public places such as theaters, libraries, churches, music listening rooms, and art rooms, and at times and places where noise must be suppressed, such as during conferences and lectures.

In order to solve such a realistic problem, the present invention is equipped with a light detecting unit and a temperature detecting unit in the mobile communication terminal, and automatically converted to the ringing mode and vibration mode in accordance with the external light and temperature changes, the complexity of the mobile communication terminal It is an object of the present invention to provide a method of changing a reception mode of a mobile communication terminal and a structure of the mobile communication terminal by a simple operation such as putting it in a pocket without undergoing an operation process.

3 is a block diagram schematically illustrating the configuration of a mobile communication terminal according to a preferred embodiment of the present invention.

The mobile communication terminal according to the present invention includes a light detector 302, a temperature detector 304, and a microprocessor 306 in addition to the existing internal configuration.

The light detector 302 including the light sensor is mounted on the outside of the mobile communication terminal to detect the intensity of the light and transmit the detected result to the microprocessor 306. The light detector 302 transmits an ON signal when the light intensity is strong, and transmits an OFF signal when the light is weak.

The light sensor detects light and converts it into an electrical signal according to the intensity of the light. The light sensor mainly uses a photodiode or a phototransistor. A photodiode forms a P layer on an N-type substrate. When light of a certain wavelength enters the PN junction, a voltage of (+) is shown in the p-type and (-) is shown in the n-type, so that photovoltaic power capable of flowing current can be obtained. Occurs. On the other hand, a photo transistor is a transistor in which a PN junction of a photodiode is used for a base-emitter junction, and there are pnp type using germanium as a material and npn type using silicon. When light enters the base surface of the phototransistor, photocurrent flows between the reverse biased base and the collector. In this way, the ON and OFF signals are transmitted by transmitting the current generated in the light detector to the microprocessor 306.

The temperature sensor 304 recognizes the temperature transmitted to the mobile communication terminal and transmits the result to the microprocessor 306. When the temperature within the preset range is detected by the temperature sensor 304, the signal of ON is transmitted, and at other temperatures, the signal of OFF is transmitted.

The temperature sensor in the temperature sensor is made using a device called a thermistor (Thermistor) whose resistance changes with temperature. Ceramic-based device (NTC: Negative Temperature Coefficient thermistor), which is made mainly of oxides such as NiO (nickel oxide), MgO (magnesium oxide), MnO (manganese oxide), and has a negative resistance temperature coefficient that decreases in resistance when the temperature increases ) And a metal element (PTC: Positive Temperature Coefficient thermistor) having a positive resistance temperature coefficient of increasing resistance value when the temperature using BaTiO 3 (barium titanate) or the like is increased. Using this element, the resistance value changes with temperature, and the ON and OFF signals are transmitted by adjusting the current value flowing through the microprocessor 306 by this resistance value.

The signals transmitted from the two detectors, the light detector 302 and the temperature detector 304 are combined in the microprocessor 306 and logically operated.

4 is a table illustrating a change in mode according to a result calculated by the microprocessor 306. As shown in this table, the mode is set to the vibration mode when the state of both the light detector 302 and the temperature sensor 304 is OFF, the ring mode when either of the two sensors are ON. However, in setting the ringing mode or the vibration mode based on the signals from the light detector 302 and the temperature detector 304, the setting varies depending on the logic structure of the logic computing device inside the microprocessor 306. Can be changed. The logical computing device may not be located inside the microprocessor 306 but may be separately mounted outside thereof.

When the ring mode is set by the combination of the logical operation device, a signal is sent to the speaker 212 to make a ring sound when receiving, and when the vibration mode is set, the signal is sent to the mobile phone vibrator 210 to vibrate without receiving a ring when receiving the vibration. Only make it ring.

5 is a flowchart illustrating a process in which a mode is switched according to a cognitive situation of a mobile communication terminal according to an exemplary embodiment of the present invention.

First, the mobile communication terminal receives a mobile phone call signal from the mobile communication switching center through the antenna 222 and the RF signal processor 220 (S510). At this time, the light detector 302 detects the light (S520). As a result, when the ON signal is generated by the light detector, when the signal is sent to the microprocessor 306, the microprocessor 206 sends an operation signal to the speaker 212 again so that the ringtone sounds (S530).

On the other hand, if the ambient light is not enough, when the OFF signal is transmitted from the light detector 302 is to perform a logical operation with the signal detected by the temperature detector 304 (S540). When the temperature sensed by the temperature sensing unit 304 is within a preset range, a signal of ON is transmitted to the microprocessor 306, and the microprocessor 306 receives the signal and operates the speaker 212 again so that the bell is closed. To ring (S530). However, when it is determined that the temperature sensed by the temperature detector 304 is out of the preset range, the OFF signal is transmitted, and the microprocessor 306 uses the mobile phone by calculating the signal and the signal of the light detector S520. Operate the vibrator 210. As a result, the reception mode operates as a vibration mode instead of the ringing mode (S550).

For example, users often carry a mobile terminal in their pocket or wear it around their neck. When walking around the neck, when an incoming call is usually received, a light sensor detects sufficient light to generate and transmit an ON signal from the light detector 302. Then, the reception mode becomes the ring mode, and upon reception, the speaker 212 is operated to ring the bell.

If the user holds the mobile communication terminal in his hand, the light detector 302 sends an OFF signal. On the other hand, the temperature sensor 304 detects the temperature transmitted from the hand and sends an ON signal. Based on these two signals, the microprocessor 306 performs the calculation to give the result of the ring mode, and upon reception, the speaker 212 operates to ring the bell (S530).

However, in meetings, lectures, or public places such as theaters, performance halls, and churches, it is only necessary to carry it in a pocket without the complicated manipulation of the mobile terminal. When the mobile communication terminal is in the pocket and receives the received signal, the light detection unit 302 of the mobile communication terminal does not detect enough light and sends an OFF signal. In addition, the temperature sensor 304 also transmits an OFF signal because it does not receive a sufficient amount of temperature from the user's body to send an ON signal. Upon receiving these two OFF signals, the microprocessor 306 enters the vibration mode and operates the mobile phone vibration unit 210 to automatically switch to the vibration mode instead of the ring mode (S550).

That is, as in the above-described embodiment, when the use of the mobile communication terminal is difficult, the mobile communication terminal is automatically switched to the vibration mode only by putting the mobile communication terminal in the pocket without a complicated operation step, and when the mobile communication terminal is taken out of the pocket, it is automatically switched to the ringing mode. Is switched.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, by simply adding a simple function without greatly modifying the existing mobile communication terminal, it is possible to automatically switch to the ring mode or the vibration mode easily without a complicated process.

In addition, when the use of mobile communication terminals such as meetings, lectures, and classes is difficult, or in public places such as theaters, performance halls, and libraries, there is no disturbing atmosphere due to ringing. In this way, the mobile terminal etiquette culture can be established.
