Description

Mobile communication terminal and method for providing dial tone by replacing music with method

The present invention relates to a mobile communication terminal and a method for providing a replacement sound by providing music, and more particularly, after the caller's mobile communication terminal acquires a traffic channel, the called party's mobile communication terminal communicates with a base station to establish a communication channel. The present invention relates to a mobile communication terminal and a method for providing a called party by replacing a dial tone signal received from a base station with music while waiting for the acquisition.

In general, in the case of a wired telephone interworking with a public switched telephone network (PSTN), when a communication channel is established by a communication protocol, a ringing tone signal (ring signal, 75Vrms, 16Hz) is transmitted from the exchange to the called party, and the calling tone is transmitted to the caller. Signal (Linbeckton signal, 75Vrms, 400Hz) is transmitted. At this time, the dial tone signal is provided to the caller through the handset speaker of the caller's telephone and the ring tone signal is provided through the ringer of the called party's telephone. In general, the ringer provides various ring tones (eg, simple music such as melody) so that the called party can call the telephone. You can select the desired ring tone on the screen.

Currently, even in the case of widely used mobile communication terminals, the base station transmits an information alarm (ringing) message to the called party's terminal so that the music set on the terminal is played when called. The sender's terminal transmits an audible tone, which is an audible frequency, to provide the dial tone as defined in the conventional tone standard to a speaker. Therefore, regardless of the type of mobile communication service provider or mobile communication terminal, the dial tone is inevitably the same.

Hereinafter, an internal configuration of a general mobile communication terminal and call processing between base stations will be described with reference to the accompanying drawings.

1 is a block diagram schematically illustrating an internal configuration of a general mobile communication terminal 100 wirelessly connected using a base station and code division multiple access (CDMA).

As shown in FIG. 1, a typical mobile communication terminal 100 currently used includes an antenna and a duplexer 105 for receiving and transmitting a signal, a radio frequency (RF) and a frequency modulation (FM) baseband. Transmitter / receiver 110, 115 for converting signals, time / frequency subsystem 120 for generating and managing frequencies, gain control system 125 for controlling propagation power and loss during transmission and reception, and each part of the system. Processor 130 to control, DTMF encoder / decoder 135 and 140 to encode and decode dual tone multi frequency (DTMF) signals and user information, codec 145 to process CD MA signals, vocoder to process voice signals 145, a signal processor 150 for processing the FM baseband signal, a full-duplex spread demodulator 155 for performing demodulation, interleaving, deinterleaving, and bitter decoding, and a power supply unit 160. Microphone / for interface A speaker 165, a ringer 170, a screen display unit 175, and a key input unit 180 are provided.

FIG. 2 is a data flow diagram illustrating each operation during call processing and call processing of a mobile communication terminal and a base station wirelessly connected using CDMA and data flow according thereto.

As shown in FIG. 2, first, the base station continuously transmits a pilot channel to all supported FAs and continuously transmits a synchronization channel message to a CDMA channel (S100). The system setting is performed by the internal operation of the mobile station. The first layer of the mobile station initialized (referred to as one layer among three layer protocols for transmitting GSM information, where GSM means "Global System for Mobile communication") is a pilot channel. It monitors the synchronization channel and receives the system setting message including the connection parameter confirmation message.

Subsequently, the calling mobile station transmits a calling message to the access channel through the connection attempt (for example, the caller enters the called party's mobile number and presses the “SEND” key) (S200). The call message is transmitted from the base station to the call channel (S300). If it is confirmed that the message of the call matching result is received through the current call channel, the mobile station transmits a call response message to the access channel through the access attempt to the base station (S400).

When the base station receives the call response message, it processes the areas of the message and selects a possible communication channel and transmits a channel assignment message through the call channel to the destination mobile station and the source mobile station. At the same time, the base station starts to transmit null call channel data (S500). Each mobile station receives a predetermined number of good frames, performs an acknowledgment procedure, and transmits a reverse call channel preamble to the base station (S600). The base station, which has acquired the reverse call channel by receiving the preamble, transmits base station confirmation command data to each mobile station (S700), and each mobile station which has received this retransmits the mobile station confirmation command data and the null call channel data (S800).

After confirming the mobile station, the base station transmits a dial tone signal to the calling mobile station (S900) and transmits an information alarm (ring) message to the called mobile station (S1000), and the calling mobile station enters the call waiting state and the called party is called. The mobile station notifies the user of the signal alarm and enters the standby state. Upon receiving a call response instruction (eg, opening the cover of the mobile phone and hooking off) when the user hears the alarm signal, the called mobile station transmits the connection command data to the base station (S1100), and the base station transmits the call between the calling mobile station and the called mobile station. The traffic channel is connected and transitioned to a call state (S1200).

The call processing procedure described above is a summary, and the procedure from the actual call instruction to the call state performs a very complicated and difficult function, and at each channel setup step, if a smooth connection is maintained or disabled and initialized, You have to listen up to 20 seconds.

There are about 15 kinds of standardized tones including dial tone, but only a few are actually used. Among them, ring tone is applied to various music. This is due to the fact that it is exposed to various outsiders, and the reason why it is easy to know that the mobile communication terminal is carried in the situation where several people are crowded, and the conventional movement outlined in FIG. The communication terminal includes a function to replace the ringing tone (ring signal) with music (meaning a set of one or more phrases) desired by the user.

For example, when a user accesses a mobile phone ringing service providing site to select a desired song and transmits the desired song to his mobile communication terminal, the transmitted song may be stored in a memory of the mobile communication terminal and used as a ringtone under the control of the processor.

Therefore, applications related to various tones, such as replacing and providing a dial tone that is frequently encountered as a ring tone, are demanded and are attracting the attention of many people. Therefore, existing mobile communication terminals to provide music by replacing the dial tone are provided. There is a need to improve.

The present invention was devised to meet the requirements as described above, and provides a menu and a user interface on the display means for downloading and storing music, selecting music, and receiving a dial tone signal from a base station. It is an object of the present invention to provide a mobile communication terminal and a method for transmitting music instead of transmitting.

The frequency transmission / reception unit 210 performs a transmission / reception function, a conversion function, and a synthesis function of a frequency signal, which will be described in more detail as follows.

The frequency transmission / reception unit 210 receives and transmits a signal through an antenna and a duplexer. The transceiver in the frequency transmitter / receiver 210 improves performance and facilitates gain control by intermediate frequency conversion. In addition, the frequency transmission and reception / processing unit 210 at the time of transmission and reception controls power through gain control, and generates a frequency required for transmission and reception using a minimum frequency source. The transmission tone transmitted by the base station along with various communication channels is also carried by the frequency transmission / reception / processing unit 210 on the carrier frequency.

The signal processing / modulation demodulator 230 performs full-duplex spreading modulation and demodulation and signal processing of the transmitted and received data, and performs CDMA signal processing, FM baseband signal processing, and voice signal processing. The signal processor / modulation demodulator 230 processes the dial tone signal to separate the carrier tone signal from the carrier frequency signal, decodes the signal, and transmits it to the speaker unit 280 so that the speaker unit 280 transmits the dial tone.

At this time, if the control unit 220 receives a control signal to prevent transmission of the dial tone data to the speaker unit 280, the signal processing / modulation and demodulation unit 230 loses the decoded dial tone data.

The memory unit 270 stores control data and a control program so that the control unit 220 can control the frequency transmission / reception / processing unit 210 and the signal processing / modulation / demodulation unit 230, and in the control signal of the control unit 220.
