The present invention relates to a mobile communication terminal, and in particular, when a physical shock is applied to the terminal above a reference value, the terminal diagnoses whether each block is damaged through its own diagnostic algorithm and displays a diagnosis result. It relates to a self-diagnosis method and apparatus thereof.

Recently, with the rapid development of communication technology, a mobile communication system has been developed and utilized in which an individual can communicate with another person while moving from an arbitrary place or from one place to another.

In addition, the mobile communication terminal used in the above-mentioned mobile communication system is provided with various additional service functions in addition to the simple call function provided in the related art.

1 is a block diagram schematically illustrating an internal configuration of a general mobile communication terminal.

In Fig. 1, reference numeral 11 denotes an antenna for wirelessly transmitting and receiving data signals, and 12 denotes demodulation and amplification of an RF signal received through the antenna 11, and is applied from the baseband converter 13, which will be described later. RF signal processing unit for outputting the transmission signal, that is, ISK signal by GMSK modulation, for example, 13 is between the RF signal processing unit 12 and the digital signal processor 16, the speaker 14 and the microphone 15 to be described later A baseband conversion unit performs digital-to-analog conversion, analog-to-digital conversion processing, and the like on a signal transmitted / received to a signal.

In addition, reference numeral 14 is a speaker for outputting the voice signal received from the baseband converter 13 as an audible sound, 15 is a microphone for converting the user's voice input into an electrical signal, 16 is coding or decoding the voice signal Digital Signal Processor (DSP), which performs an equalizer to remove multipath noise and performs audio-related data processing, etc., 17 is a microprocessor that controls the overall device, which is the RF signal processor 12 ) And the DSP 16 or interleaving, block coding, and convolutional coding are performed on data transmitted and received.

In addition, reference numeral 18 denotes a module for storing a subscriber's related functions and processing of various services for subscriber's network function and subscriber's network information and subscriber's registration information, and performing a kind of operation as a detachable module. Subscriber Identity Module (SIM) that acts like a key, 19 is a program memory that stores the function of the terminal and protocol software for processing messages sent and received from the network, 20 is a numeric key and A keypad composed of a function setting key, etc., 21 is an LCD display unit for displaying an operating state of the terminal as an LCD, and 22 is a data storage unit serving as a data buffer when the terminal operating program is executed.

That is, in the mobile communication terminal having the above configuration, when the user turns on the power of the mobile communication terminal, the microprocessor 17 moves the antenna 11 while sequentially increasing or decreasing the demodulation frequency of the RF signal processing unit 12. In addition to searching the wireless carrier received through the base station (not shown) to which it belongs based on the level of each demodulated signal inputted.

At this time, the microprocessor 17 stores the control data for controlling the RF signal processing unit 12 and the level of the received data input through the baseband conversion unit 13 in the data storage unit 22 and then stores the control data. The demodulation frequency of the RF signal processing unit 12 is set based on the reception frequency having the large level value.

The microprocessor 17 receives a broadcast channel (BCCH) from a base station (not shown), grasps information of the base station, and stores its information stored in the subscription information storage unit 18 according to the LAPDm protocol. The registration procedure is performed by reading the International Mobile Subscriber Identity (IMSI) and transmitting it to the base station.

Request) or whether a handover command has been received from the base station.

When the call channel is received, the call response is performed to the base station and the alarm signal output unit of the mobile communication terminal is driven to alert the user that there is a call from another terminal. If there is a request, after detecting a key input from the keypad 20, the access request is executed by sending a random access channel (RACH) to the base station.

In this case, when an access grant channel (AGCH) is received from the base station, after executing the call response, a call can be made between the user and the user of another terminal by transmitting and receiving a voice signal through an assigned time slot. Will be.

On the other hand, the mobile communication terminal is a communication device that allows the user to talk to other people while on the move, so that the user can easily take the terminal anywhere by carrying the terminal in a bag or a top or bottom pocket to carry a phone call with another person. It becomes possible.

However, as described above, if a user severely collides with another person or an object while moving the mobile communication terminal or drops the terminal during use, a physical shock is applied to the terminal so that the terminal can no longer be used. Will occur.

At this time, the user visually inspects the terminal damaged by physical shock, and if it is determined that there is no abnormality, the user may use it as it is, and if the terminal is determined to be damaged, request a repair to a service center.

However, since the user cannot determine whether the degree of failure of the damaged terminal is minor, severe or which of the terminal is broken, there is a problem that only the service center staff who has requested the repair can only check the details.

In addition, since the user cannot immediately check the degree of failure of the terminal, there is a problem in that it is not possible to know in detail how much time and cost for troubleshooting.

Accordingly, the present invention has been made in view of the above circumstances, and when the terminal is subjected to a physical shock from the outside, the terminal executes a self-diagnosis function to determine whether there is damage inside the terminal and to display it. And to provide the device.

Characterized in that configured to include.

That is, according to the present invention having the above-described configuration, when a physical shock applied from the outside is detected, the control means reads out a standard allowable value and compares it with the shock detection signal, and if the shock detection signal is large, the self-diagnosis algorithm is executed. In addition to determining whether there is an abnormality in each block of the terminal, the determination result is displayed by the display means.

Therefore, the user can check whether the mobile communication terminal is damaged or the part of the damaged block due to the physical shock.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention.

FIG. 2 is a block diagram showing an internal configuration of a mobile communication terminal having a self-diagnosis function according to an embodiment of the present invention. In FIG. 2, the same reference numerals are used for parts performing the same functions as those shown in FIG. And reference numerals and detailed descriptions thereof are omitted.

In FIG. 2, reference numeral 31 denotes an impact detecting unit for detecting the magnitude of a physical shock applied from the outside and converting the electrical shock into an electrical signal, and reference numeral 32 denotes a reference data storage unit for storing the allowable physical shock as reference data. Is a program memory for storing a function of a terminal and protocol software for processing a message transmitted and received with a network, and executing a self-diagnosis algorithm according to a predetermined control signal. The test item of the self-diagnosis algorithm is, for example, a memory test. It is divided into Audio Test, Tx Test, Rx Test, Location Updating Test, and Accessory Test.

In addition, in FIG. 2, reference numeral 34 denotes that when a physical shock is detected through the shock detector 31, the detected shock detection signal is compared with the external shock tolerance reference data previously registered in the reference data storage unit 32. When the shock detection signal is large, the diagnostic test is performed on each block inside the terminal by executing the self-diagnosis algorithm stored in the program memory 33. When the diagnostic test is completed for each block, the diagnosis result is displayed through the LCD display 21. The microprocessor that controls the display.

Next, the operation of the apparatus having the above-described configuration will be described with reference to the flowchart shown in FIG.

First, when the user turns on the terminal (ST11), when an external physical shock is applied to the terminal, the shock detection unit 31 detects a physical shock and the detected physical shock value. The digital signal is converted into an electric digital signal and the shock detection signal is output (ST12).

Thereafter, when the shock detection signal is output from the shock detection unit 31, the microprocessor 34 reads out the shock tolerance value previously registered in the reference data storage unit 32 (ST13). The shock detection signal output from the unit 31 is compared (ST14). If the shock detection signal is smaller than the shock allowance read as a result of the comparison, the operation of performing the ST12 detecting the shock is repeated, and the shock detection signal is read as a result of the comparison. When the value is larger than the allowable impact value, the self diagnosis algorithm stored in the program memory 33 is executed (ST15).

In addition, the microprocessor 34 executes a self-diagnosis algorithm stored in the program memory 33. The test items are, for example, memory (Memory Test), audio (Audio Test), transmission (Tx Test), and reception ( Rx test), location checking (Location Updating Test), accessory test (Accessory Test), etc. are executed, and when the diagnosis of the test item is completed, the presence or absence of output according to each item is output (ST16).

After that, when the diagnosis result is output through the self-diagnosis algorithm of the program memory 33, the microprocessor 34 displays the message as a message such as a pass or a failure through the LCD display 21. (ST17).

On the other hand, if the terminal is a fatal damage, ie damage to the motherboard or memory damage due to external physical shocks, the self-diagnosis algorithm cannot be performed.

That is, according to the above embodiment, the terminal detects a physical shock applied from the outside, compares it with the shock tolerance value, which is pre-registered reference data, and executes the self-diagnosis algorithm when the detected shock is larger than the shock tolerance value. In addition to determining whether there is an abnormality in each block of the terminal, an abnormality is displayed as a message.

In addition, this invention is not limited to the said Example, It can variously deform and implement within the range which does not deviate from the technical summary of this invention.

For example, referring to a memory test execution example through the self-diagnosis algorithm of the program memory 33, the self-diagnosis algorithm reads / writes data registered in a flash memory and an EEPROM provided in the terminal. Repeatedly displays the result as a pass or fail message.

In addition, the audio test is processed in order of the microphone 15, the speaker 14, and the buzzer (not shown). First, an audio loop back is executed.

Here, the audio loop back is a speaker 14 through the baseband converter 13 and the DPS 16 to the voice detected from the microphone 15 (Mic) through the self-diagnosis algorithm of the program memory 33. By sending out to the device, it is tested whether the elements of the baseband conversion section 13 operate properly. Then, by outputting a specific frequency (audio frequency) through the speaker 14 and the buzzer at a predetermined level of power, it is checked whether the operating states of the speaker 14 and the buzzer are normally operated.

Also, the TX test is a test for transmitting data from a terminal to a base station. For example, when a ″ 1 to 120 ″ arbitrary channel is transmitted to a ″ 5 to 19 ″ power level, it is correctly entered into the power ramping table of the base station. Check it. At this time, it is checked whether the RF signal processing unit 12 operates normally. If the RF signal processing unit 12 does not operate normally, the test is terminated because it is a hardware error.

In addition, the RX test tests whether data transmitted from the base station is normally received by the terminal. The RX signal detected through the DSP 16 is checked whether or not it is correctly calculated with a value defined in a gain table of an auto gain control. This can be seen by comparing the gain table) value with the value received by RSSI.

In addition, the Location Updating Test performs a Location Updating when both the TX Test and the RX Test pass, and the location updating test is performed. By registering, the main routine of the terminal is read out and executed, not by the self-diagnosis algorithm of the program memory 33.

In addition, an accessory test is a test of an additional device in the terminal, and checks whether the LED, the backlight, the battery, the LCD display unit 21 and the like operate normally.

As described above, according to the present invention, when a physical shock is applied to the terminal, the self-diagnosis method of the mobile communication terminal is configured to execute the self-diagnosis algorithm based on the detected shock value and display the test result on the screen, and The device can be realized.
