The present invention relates to a mobile terminal, and more particularly, detects a residual level of a battery for supplying power to a mobile terminal, and based on the detected level, a ringing sound capable of differently outputting a ringing sound generated when a call signal is received. The present invention relates to a mobile terminal having a battery level indication function used.

Recently, with the rapid development of communication technology, a mobile terminal 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. Such a mobile terminal is a trend in which more efficient and convenient functions are added beyond the function as a simple call equipment provided in the related art.

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 It is a digital signal processor (DSP) that performs an equalizer to remove multipath noise and performs audio related data processing functions.

In addition, reference numeral 17 denotes a microprocessor for controlling the overall device, which controls the RF signal processing unit 12 and the DSP 16 or interleaving, block coding, and convolution for data transmitted and received. Performs coding (Convolution Coding), 18 is a Subscriber Identification Module (SIM) that stores the subscriber's registration data, 19 is a protocol software for processing the functions of the terminal and messages sent and received from the network is stored Program memory 20 is a keypad composed of numeric keys and various function keys.

In addition, reference numeral 21 is a display unit for displaying the operation state of the terminal in liquid crystal display (LCD), 22 is a data storage unit serving as a data buffer when the terminal operating program is executed, and 23 is local information related to a telephone such as a telephone number. Is an information storage unit (E ² PROM) stored non-volatile.

That is, when the user turns on the power of the mobile terminal, the microprocessor 17 receives through the antenna 11 while sequentially increasing or decreasing the demodulation frequency of the RF signal processor 12. In addition to searching for a wireless carrier, the base station (not shown) to which it belongs is determined based on the level of each demodulated signal input.

At this time, the microprocessor 17 stores the control data for controlling the demodulation signal and the level value of the received reception data in the data storage 22, and sets the demodulation frequency based on the reception frequency having the largest level value. Done.

Then, the microprocessor 17 receives the broadcasting channel (BCCH) from the base station (not shown), grasps information of the base station, and stores its subscriber in the subscription information storage unit 18 according to the LAPDm protocol. The registration procedure is performed by reading the information TMSI and transmitting it to the base station.

Then, the microprocessor 17, in the state where the registration process is completed, whether a paging channel (Paging CHannel) is received from the base station, the user operates the keypad 20 to make a transmission request (call request) to the base station, or the base station Detect whether a handover command has been received.

Therefore, when a call channel (PCH) is received, the call response to the base station is executed and the alarm signal output unit (not shown) of the mobile terminal is alerted to the user that there is a call from another terminal. When a user's transmission request is requested, the access request is executed by transmitting a random access channel (RACH) to the base station after detecting a key input from the keypad 20.

In addition, after receiving an access grant channel (AGCH) from the base station or executing a call response, the user can make a call between the user and the user of another terminal by transmitting and receiving a voice signal through the assigned time slot. do.

On the other hand, the mobile terminal operates by being supplied with power through a battery. When the battery is discharged, the mobile terminal replaces or recharges a charged battery.

Therefore, the mobile terminal displays the remaining amount of battery through the display means, and the user checks this to determine when to replace the battery.

However, when a user goes out for a long time without checking the battery level of the mobile terminal and frequently uses the mobile terminal, there is a problem that the battery is discharged and the mobile terminal cannot be used.

Accordingly, the present invention has been made in view of the above circumstances, and detects the remaining battery level of the battery supplying power to the mobile terminal so that the ring sound generated when receiving a call signal can be output differently according to the detected battery level. The purpose of the present invention is to provide a mobile terminal having a battery level indication function using a ring sound.
