Hereinafter, by the present invention of the configuration as described above, it will be described in detail with reference to the accompanying drawings the positioning device of the PGM phone.

The PMG PHONE has a Bluetooth communication function added to a mobile terminal for mobile communication. In particular, the mobile terminal MS is connected to a base station RAN to be controlled and monitored by a mobile switching center MSC. In the state, the control signal of the mobile switching center (MSC) to directly control the other MBG phone in close proximity to the MPG phone and Bluetooth.

For example, when a PGM phone wirelessly connected to a base station RAN is provided with a game program from a mobile switching center (MSC) and is wirelessly connected with another PGM phone in the vicinity in a Bluetooth (BLUETOOTH) manner to play a game, the Bluetooth Other PGM phones connected to are also directly controlled by the MSC through a PMS phone directly connected to the MSC.

The PMG phone having the above functions integrates an expensive function including a GPS function for receiving and analyzing location information from a GPS satellite, a TV broadcast reception function, a camera function, and the like. It is easy to lose because it is expensive.

In the case of losing the expensive PMG phone as described above, it is to easily find the location by checking the corresponding position, in particular, the supply of the built-in auxiliary power supply in the state that the supply of the main power is cut off, to the GPS set every predetermined cycle time It is a technique of the present invention to find a lost PGM phone because it notifies the accurate location information by Bluetooth communication of low power consumption.

The main power supply unit 100 of the PGM phone supplies normal operation power to each functional unit including the control unit 120 and the mobile communication unit 140, and when the mobile communication is to be performed, the control unit 120 The mobile communication unit 140 wirelessly connects to the base station RAN through the mobile communication unit 140 controlled to be activated by the control and performs mobile communication. The mobile communication unit 140 activated as described above and wirelessly communicates with the base station RAN is about 300 mA per hour. Each of the functional units including the control unit 120, which consumes a relatively large current of about 400 mA, consumes a relatively large amount of current, but uses a clock signal that generates a precise clock signal.

When the PMG phone is to check its current location, the GPS unit 150 is activated by the control of the controller 120, and the latitude, longitude, elevation, and time information obtained by wirelessly analyzing the location information from the GPS satellite. Is applied to the control unit 120, the GPS unit 150 consumes a current of several tens of mA per hour.

When the PGM phone is to communicate with another PGM phone located in a short distance using Bluetooth, the Bluetooth unit 170 under the control of the control unit 120 is activated to communicate in a Bluetooth (BLUETOOTH) method, the Bluetooth unit 170 consumes about 30 mA of current.

The MPG phone is not directly related to the description of the present invention, and is relatively expensive since various functions such as a TV broadcasting viewing function unit, a camera function unit, and an MP3 function unit are integrally provided.

If the PGM phone is lost, if the main power supply 100 is normally operated, the GPS unit by the control unit 120 received a remote control command of the mobile switching center (MSC) connected through the mobile communication unit 140 Since 150 receives the GPS location information and provides the received GPS location information to the mobile switching center through the mobile communication unit 140, the lost location is easily found.

However, for various reasons, when the main power supply unit 100 does not supply the operating power of a normal level or when the supply of the operating power is cut off, the mobile communication unit 140 that consumes much current cannot be activated.

The control unit 120, when the main power supply unit 100 supplies abnormal operating power, or the supply of the operating power is cut off, the control unit 120 is switched to the auxiliary power supply unit 110 that is integrally built in the PMG phone, The control unit 120, which is the minimum functional unit for communication, the auxiliary oscillator 130 with low power consumption, the GPS unit 150 for receiving location information, and the Bluetooth unit 170 for short-range communication in a Bluetooth manner. Supply the operating power.

The auxiliary power supply unit 110 is charged by the main power supply unit 100, the magnitude of the current that can be supplied is small, and in order to receive the position information of the PMG phone for a long time with a small operating current as described above, Bluetooth The PGM communication method by (BLUETOOTH) is used.

When the operating power is supplied from the auxiliary power supply unit 110, the control unit 120 allows the GPS unit 150 and the Bluetooth unit 170 to operate in a sleep mode, and the auxiliary oscillation unit 130 is operated. The timer receives the clock signal applied from the device and drives the timer to count the predetermined time unit, for example, one hour unit.

When the set time is counted as one hour, the controller 120 activates the GPS unit 150 to receive the GPS location information from the GPS satellite, and analyzes the received information to determine the latitude and longitude of the current location. Detect sea level information and measurement time information.

The GPS unit 150 operates normally when receiving a corresponding signal from at least three GPS satellites among a plurality of GPS satellites floating in the Earth's orbit, and receives the corresponding signal from more GPS satellites. In this case, position information with increasing precision is received.

The GPS unit 150 operates by a clock signal applied from the auxiliary oscillator 130, and the position information for successfully receiving, analyzing, and outputting the position information as described above is applied to the comfort unit 160. .

The comfort unit 160, which can be replaced by a GPIO function unit, consumes almost no operating current, and outputs the input location information to the Bluetooth unit. Activate unit 170.

The Bluetooth unit 170 records and stores the position information applied through the comfort unit 160 in the allocated area, and by the clock signal applied from the auxiliary oscillator 130, by the normal operating power in the vicinity of the vicinity. Whether there is a pgm phone operating normally is searched and connected for a predetermined time set using a Bluetooth signal, for example, 10 minutes.

The Bluetooth unit 170 transmits the location information to a pgm phone near the connected neighbor as a pgm communication using a Bluetooth signal.

As described above, the PMG phone, which has received the location information based on the Bluetooth communication of the PA, controls its own GPS unit 150 to receive its own location information, and moves itself with the location information received through the PMG communication. Since the wireless transmission to the base station (RAN) through the communication unit 140, and transmits to the mobile switching center (MSC), the mobile switching center (MSC) notifies the service provider to find the lost phone, thereby confirming the location information of the lost phone .

That is, according to the present invention, the main power supply unit 100 of the lost PGM phone consumes almost no current to supply normal operation power, or the operation power supply is deliberately cut off due to various reasons. When the operation power is supplied from the built-in fixed auxiliary power supply unit 110, and receives the location information at a set time period and transmits to the pMG phone of the neighboring neighborhood in normal operation by the pMG communication method of Bluetooth, the nearby pMG phone It transmits the location information to the mobile switching center (MSC) through.

Therefore, there is an advantage of transmitting the position information of the pMG phone to the normally operated PGM phone using the Bluetooth signal consuming a small current, and transmitting the position information to the mobile switching station using the PM phone that operates normally.

Hereinafter, with reference to the accompanying Figure 4, by the present invention, a method of transmitting position information of the PWM phone.

If the main power is not normally supplied to the PGM phone, it is switched to an auxiliary power supply and supplies operation power to the control unit 120, the auxiliary oscillator 130, the GPS 150, and the Bluetooth unit 170, which are the minimum functional units for the PGM communication. When the predetermined time is set by driving the timer, the GPS unit 150 is activated to receive the GPS position information, and transmits to the activated Bluetooth unit 170 to record and store the sleep mode, and maintains the sleep mode. The activated Bluetooth unit 170 may search for and connect to a nearby PGM phone capable of communicating with Bluetooth for a predetermined time, and maintain a sleep mode after transmitting the GPS position information. It consists of a series of processes that repeat until.

When the operating power is not normally supplied from the main power supply unit 100, the controller 120 of the PGM phone switches to the fixed built-in auxiliary power supply unit 110 and supplies the operating power to the minimum essential functional unit for PGM communication. Determining whether the normal operating power is supplied from the main power supply unit 100 by the control unit 120 (S100); If the main power supply unit 100 does not supply the operating power in the process (S100), the step of switching the auxiliary power supply unit 110 fixed to the PGM phone to supply the operating power (S110); Supplying operating power to the minimum essential functional unit of the PGM communication including the control unit 120, the auxiliary oscillator 130, the GPS unit 150 and the Bluetooth unit 170 from the auxiliary power unit 110 of the process (S110). Transfer process consisting of a process (S120),

The Bluetooth unit 170 receiving the position information of the GPS process records and stores in the allocated area and searches the surrounding PGM phones to transmit the recorded PS position information to the Bluetooth of the PGM communication and sleep if accessible within a predetermined time. Maintaining the mode (SLEEP MODE), the activated Bluetooth unit 170 records and stores the input location information in the allocated area, and searches for the presence of the MPG phone capable of Bluetooth PM communication from the surrounding area (S170). ); In step S170, a step of searching for a pMG phone from the surroundings and determining whether the connection is made in a Bluetooth (BLUETOOTH) method (S180); A step of wirelessly transmitting GPS position information by Bluetooth to the connected PGM phone searched in step S180 (S190); In the process (S180), if it is not possible to search and access the surrounding PGM phones, it is determined whether a predetermined time has elapsed, and if the predetermined time has not elapsed, feedback to the process (S170) is repeated (FEEDBACK) to repeat search of surrounding PGM phones. Process S210; In the above process, if the location information is wirelessly transmitted through Bluetooth (S190), or if the neighboring PMG phone (PMG PHONE) cannot be searched and connected for a predetermined time (S210), the Bluetooth unit 170 is kept in the sleep mode (SLEEP MODE). Operation (S200), the transfer to the transfer process (S100) is fed back to the (FEEDBACK) consists of a Bluetooth process consisting of a process (S200) to repeat the above process.

Hereinafter, according to the present invention having the configuration described above, a method of transmitting positioning information of a PWM phone will be described in detail with reference to the accompanying drawings.

The control unit 120 of the PGM phone determines whether the operating power is normally supplied from the main power supply unit 100 (S100), and in the determination (S100), the main power supply unit 100 does not supply normal operating power or power. When the supply is cut off, switching to the auxiliary power unit 110 (S110), the operating power of the auxiliary power unit 110 is the minimum essential functional unit for the PGM communication, for example, the control unit 120, the auxiliary oscillator 130 ), The GPS unit 150, the Bluetooth unit 170 to supply the operating power (S120).

Since the controller 120 drives the timer according to a clock signal applied from the auxiliary oscillator 130, the controller 120 counts a predetermined time, for example, one hour (S130), and determines whether the count of the set time is completed. If it is determined (S140), if the coefficient is not completed, the transfer to the transfer process (S100).
