How to Automatically Send a Cell Phone Number

1 is a schematic block diagram of a conventional cell phone.

2 is a flowchart of transmitting a telephone number dialed from a conventional cellular phone to a cell site.

3 is a control flowchart for automatically transmitting a telephone number dialed in a cellular phone according to the present invention to a cell site.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cellular phone. In particular, the operating concept of the cellular phone is the same as the operating concept of a cordless telephone, and after a predetermined time elapses after dialing a desired telephone number, the dialed telephone number is a cell site. The present invention relates to a method of transmitting a telephone number of a cellular phone, which is automatically transmitted.

A conventional cellular phone will be described with reference to the accompanying drawings.

1 is a schematic block diagram of a conventional cellular phone, and FIG. 2 is a flowchart of transmitting a dialed telephone number of a conventional cellular phone to a cell site. As can be seen in FIG. 1, the portable telephone includes a central processing unit 1 for controlling the overall operation of the telephone, a receiving unit 2 for receiving a signal input from the antenna 9 through the duplexer 5; A transmitter 3 for outputting a transmission signal to the duplexer 5 antenna 9 side, a frequency synthesizer 4 for supplying demodulated and modulated signals to the receiver 2 and the transmitter 3 side, and a keypad unit ( A memory unit 6 for temporarily storing telephone numbers and the like from 10) and outputting them to the central processing unit 1; and a liquid crystal display unit for displaying call information in accordance with data from the central processing unit 1; ), And process the received voice signal and output it to the speaker for speaker (SPK) side, process the voice signal from the microphone for microphone (MIC), output it to the central processing unit (1), and output the signal signal to the buzzer for buzzing sound (BZ). Audio processing unit 7 for outputting to the "

A method of transmitting a dialed telephone number to a cell site in a conventional cellular phone configured as described above will be described with the flowchart of FIG. 2.

When the user of the cellular phone supplies power with the power key installed in the cap part 10 (step 11), the central processing unit 1 enters a mode for operation (step 12) and then at the cell site. Select two channels having the best received field strength (RSSI) among the channels allocated for communication with the cellular phone. Thereafter, the state of the cellular phone is switched to the idle state, and the radio frequency signal received from the cell site of the supporting station or the telephone number of the user supplied from the keypad unit 10 is waited for (step 13). ). When detecting the telephone number dialing signal supplied from the keypad unit 10 (step 14), the telephone number is temporarily stored in the memory unit 6, and then the Send Key input of the keypad unit 10 is sensed. (Step 15). If no input of the Sen key is detected after a predetermined period of time, execute step 11 to select two new channels with good reception field strength (RSSI) among the allocated channels and wait for the input. If detected, the central processing unit 1 amplifies and modulates the cell phone-specific ID number, the ESN signal, and the dialed telephone number temporarily stored in the memory unit 6 through the transmitter unit 3 to the cell site side. Thereafter, the data is transmitted through the duplexer 5 and the antenna 9 (step 16). If it is determined that the cell site and the voice channel for transmission / reception are formed (step 17), and the voice channel is not formed, step 11 is executed again from the initial stage. After the step 17 is executed, the cell site and the voice channel are established, and the cellular phone user calls the other party dialed as the microphone MIC and the speaker SPK.

As described above, the conventional cellular phone has a problem in that a call cannot be formed by dialing a desired counterpart phone number after pressing a caller's desired number by considering an operation recognition that a user thinks as an operation concept of a cordless telephone. In addition, after dialing a desired telephone number, there is a cumbersome problem of pressing a key to be transmitted.

The present invention has been made in view of the above-mentioned problems, and after a predetermined time elapses after dialing the telephone number of the intended party, the telephone number of the dialed party is automatically sent to the cell site to form a call. There is this.

In order to achieve the above object, the present invention provides a method for selecting a channel having the best received field strength (RSSI) among channels allocated by a cell site after entering a mode for starting operation when power is supplied. A second step of determining a high frequency signal supplied from a cell site of a supporting station or a dialing signal supplied from a keypad part after performing the first step; and a dialing signal after performing the first step. When supplied, the stored dialing signal is temporarily stored and transmitted to the cell site after a predetermined time has elapsed. If the dispensing key is input before a predetermined time elapses, the temporarily stored dialing signal is transmitted to the cell site. Step 3 and, if the voice channel of the signal transmitted to the cell site side is connected, the fourth step of talking to the other party and performing the first step if the voice channel is not connected It provides a phone number automatic transmission method of the cell phone comprising a.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, an embodiment of a method for automatically transmitting a phone number of a cellular phone.

3 is a control flowchart for automatically transmitting a telephone number dialed in a cellular phone according to the present invention to a cell site.

When the cell phone user supplies the power by driving the power key (step 1), the central processing unit enters a mode for operation (step 2), and the channel allocated to the cell phone side to be used by the cell site side. Among them, two channels having the best received field strength (RSSI) are selected and secured. Thereafter, the state of the cellular phone is switched to the idle state, and the user waits for the dialing input of the user supplied from the keypad or the high frequency reception signal supplied from the cell site. When the dialing signal supplied from the keypad is sensed (step 4), the dialing signal supplied from the keypad is temporarily stored in the memory and then waited for a predetermined time (about 5 seconds) (step 5). After a predetermined time elapses, the CPU transmits the temporarily stored dialing signal, the unique ID number of the cellular phone, and the ESN signal to the cell site (step 7). After executing Step 4, if the Send Key is input and the Send Key is input before the predetermined time elapses, the temporarily stored dialing signal, the unique ID number of the cellular phone, and the ESN signal are transmitted to the cell site of the base station. The data is sent to the (Cell Site) side (step 7). After the transmission is completed, determine the voice channel connection between the cell site and the cellular phone in use (step 8). When the voice channel is connected, the user talks to the dialed party (step 9). If a failure occurs and the voice channel is not connected, perform step 3.

As described above, according to the present invention, after a predetermined time (about 5 seconds) has elapsed after dialing the telephone number of the other party to be called, the dialed telephone number is automatically sent to form a call path.

Claims (1)

After the power is supplied, enter the mode for starting operation, and then select the channel having the best received field strength (RSSI) among the channels allocated by the cell site of the support station, and performing the first step.
