The present invention relates to a communication method of a mobile communication terminal, and more particularly, to a multiple outgoing call method of a mobile communication terminal.

In general, a mobile telephone (wireless telephone) is a device that performs a communication function by forming a radio link (RF link) with a nearby cell site (mobile telephone, wireless telephone) in the mobile state, there are a mobile phone and an automobile phone, etc. . Such a mobile communication terminal dials a received telephone number when a user inputs a telephone number and then presses a send key when attempting an outgoing call, and transmits by dialing the received telephone number. FIG. 1 illustrates a configuration of a control unit for performing dialing in the mobile communication terminal as described above, and the configuration of the communication unit of the mobile communication terminal is omitted. FIG. 2 is a memory map configuration of the RAM 13 of FIG. 1 as described above, and shows a memory map configuration for dialing. In this case, as shown in FIG. 2, the RAM 13 is configured to dial only one telephone number, and dials one telephone number at a time by using a calling key.

3 and 4 illustrate a process of performing a dialing function in a mobile communication terminal having the above configuration.

First, referring to FIG. 3, when the user generates dial information by using the keypad 15, the microprocessor 11 receives dial information generated by the keypad 15 in step 302 to display a RAM as shown in FIG. 2. Store in (13). When the originating key is received from the keypad 15, the microprocessor 11 recognizes this in step 303, and drives a DTMF generator (not shown) in step 304 to perform a dialing function. When the response signal is received from the subscriber on the other side, the microprocessor 11 transitions to the call state in step 305 to service the call mode. To transition to. In this case, after performing the dialing in step 304, if the subscriber is determined to be busy, another telephone number must be dialed or the same telephone number must be dialed manually.

With reference to FIG. 4, another conventional outgoing call execution process will be described. When the user generates dial information using the keypad 15, the microprocessor 11 receives the dial information generated from the keypad 15 in step 402 and stores the dial information in the RAM 13 as shown in FIG. 2. When the originating key is received from the keypad 15, the microprocessor 11 recognizes this in step 403 and performs a dialing function in step 404.

After performing the dialing, the microprocessor 11 checks whether the other party subscriber is in a busy state in step 405, and transitions to the call mode in step 406 if it is idle. When the end key is generated in the state of performing the call function as described above, the microprocessor 11 recognizes that the end key is received in step 409, thereby releasing the call state and transitioning to the standby state.

In this case, after the dialing is performed, when it is determined in step 405 that the other party is busy, the microprocessor 11 checks whether the redial function is set in step 407. If the redial function is not set, the process proceeds to step 406 to maintain the call mode. However, if the redial function is set in step 407, after the call is terminated in step 408, a predetermined time is waited to perform redial. When the waiting time ends, the process proceeds to step 404 again to repeat the dialing function.

The above process is always performed while the end key is received, and when the end key is received while the redial is being performed, the outgoing call attempt process is terminated.

As described above, in the cellular type mobile communication terminal, if the other party is busy, even if there is another phone number to talk to the other party, after finishing the ongoing call, input another phone number again and press the call key to retry the call. There was discomfort to be.

Accordingly, an object of the present invention is to provide a method for easily performing an outgoing call in a mobile communication terminal.

Another object of the present invention is to provide a method for performing a multiple outgoing call function by automatically dialing a phone number in an idle state when a mobile communication terminal attempts to make an outgoing call.

Hereinafter, the present invention will be described in detail with reference to the drawings.

5 is a block diagram of a control unit of a mobile communication terminal for carrying out the present invention, and the configuration of the mobile communication terminal except for the control unit is omitted.

Referring to FIG. 5, the microprocessor 51 controls the overall operation of the mobile communication terminal and performs an operation of automatically dialing an idle phone number when attempting an outgoing call. The ROM 52 stores a program for controlling the overall operation of the mobile communication terminal, and stores an automatic dialing program for performing the present invention. The RAM 53 temporarily stores data generated during program execution. Save function. The display unit 54 performs a function of displaying the state of the mobile communication terminal and the received data under the control of the microprocessor 51. The keypad 55 generates various key commands and key data generated by the user and outputs them to the microprocessor 51. The tone detector 56 decodes various tone signals received and outputs them to the microprocessor 51.

6 is a configuration diagram of an outgoing buffer allocated to the RAM 53 for carrying out the present invention, and has a region capable of storing a plurality of telephone numbers for multiple outgoing.

7 is a flowchart illustrating a process of performing an outgoing call in a mobile communication terminal according to the present invention, and attempts to dial by sequentially accessing available phone numbers when attempting an outgoing call, and automatically connects to a non-calling subscriber. And an operation process in which a call function is performed.

The present invention will be described in detail with reference to the flowchart of FIG. 7 based on the configuration of FIGS. 5 and 6 described above.

First, in order to perform a multi dialing function, a user must input a plurality of telephone numbers or addresses in which a plurality of telephone numbers are stored through the keypad 55 to distinguish the identifiers. This is when the outgoing call is attempted to share a lot of phone numbers, such as government offices and companies, the busy signal is frequently generated due to the high volume of calls. In this case, multiple phone numbers or addresses containing multiple phone numbers are entered at one time using the identifier to automatically connect to a telephone in an adjacent location and perform a call function. That is, in order to serve a multiple outgoing call function in a place having multiple telephone numbers, the telephone numbers of adjacent locations and the telephone numbers of the same department should be input and stored. That is, in order to perform the multi-outgoing call function as described above, the user of the mobile communication terminal inputs N phone numbers or addresses using the identifier through the keypad 54.

When the telephone number is input by using the telephone number and the identifier key, the user can use the keypad 55 to call "phone number 1 + identifier key + telephone number 2 + identifier key + telephone number 3 + identifier key +-". -+ Phone number N + call key "must be pressed. In addition, when a plurality of phone numbers are input by using a phone number previously input in order to perform a speed dial function, a user may use a corresponding address and an identifier key of a memory storing the speed dial number using the keypad 55. Press. Therefore, in this case, for example, "Address 1 + Identifier Key + Address 2 + Identifier Key + Address 3 + --- + Address N + Outgoing Key" may be generated. In this case, the identifier key is input using a separate key. Here, the identifier key used with the phone number may use "," and the identifier key used with the memory address may use "/".

When the telephone number or the memory address information generated from the keypad 55 is received by the user as described above, the microprocessor 51 receives the RAM 53 having the structure as shown in FIG. Store in a buffer. Looking at the configuration of the outgoing buffer, the LCD buffer is a buffer for storing the current dialing telephone signal is output to the display unit 54 under the control of the microprocessor 51 to display the current dialing flashing data Is stored as. The telephone number pointer is a pointer indicating a telephone number currently being dialed, and is an address pointer of the telephone buffer currently dialed among the telephone buffers. The call buffer (originate buffer) is a buffer for storing a telephone number for dialing and transmitting substantially during dialing, and stores the same information as the telephone number stored in the LCD buffer.

When the originating key is received in the above state, the microprocessor 51 recognizes this in step 702, and checks whether there is an identification code in the originating buffer of the RAM 53 as shown in FIG. At this time, if there is no identification code, the microprocessor 51 stores the telephone number in the dial buffer in step 704 to perform the general calling mode, and performs the dialing function in step 705. Thereafter, the microprocessor 51 proceeds to the call mode in step 706 and performs the call mode as described above until the end key is received. When the end key is generated, the microprocessor 51 recognizes this in step 707 and terminates the call mode and then transitions to the standby state.

However, if there is an identification code in step 703, the microprocessor 51 proceeds to step 708 and initializes the telephone number indicator to "0", initializes the number of call attempts and time values, and then performs the multi-call mode. Do it together.

When the multiple call mode is performed as described above, the microprocessor 51 reads the stored phone number or the phone number in the address of the telephone buffer indicated by the telephone number indicator stored in the calling buffer of FIG. Move to LCD buffer. The microprocessor 51 reads the phone number stored in the LCD buffer in step 710 and flashes the current dialing phone number on the display unit 54. In step 711, the microprocessor 51 dials the phone number on the call buffer. .

In operation 712, the microprocessor 51 enables the tone detector 56 to receive a tone signal indicating the status of the other subscriber, and checks whether the tone signal received in step 713 is a busy tone. . In this case, when the busy tone is not received, the microprocessor 51 controls the display unit 54 to stop the blinking display operation of the phone number in step 714, and the beep tone indicates a successful call. In step 706, the call function is performed. Therefore, when the subscriber of the dialed telephone number is not in the busy state in the multi-outgoing mode, the microprocessor 51 stops the display operation of the flashing display phone number and generates a tone signal indicating the success of the call and returns to the call mode. Transition

However, when the dialing is received as a result of dialing the phone number stored in the call buffer in step 713, the subscriber of the corresponding phone number is busy. Thus, the microprocessor 51 proceeds to step 715. End the call and wait for a while. Thereafter, the microprocessor 51 increases the value of the telephone number indicator by one in step 716 and initializes it to "0" when the value of the telephone number indicator is larger than the threshold value N-1. In operation 717, the microprocessor 51 increases the number of call attempts or the time value, and then, in step 718, the microprocessor 51 checks whether the number of call attempts exceeds the limit or the call attempt time exceeds the time limit. In this case, if the call limit or time limit is not applied, the process returns to step 709 to access the next phone number and automatically performs the outgoing call operation in the same manner as described above.

However, when the number of attempts to limit the call is exceeded or the number of attempts to limit the call is exceeded in step 718, the microprocessor 51 controls the display unit 54 to maintain and display the flashing display phone number in step 719. You will hear a beep indicating failure. The process proceeds to step 707 to prepare for the next state.

As described above, in the cellular type mobile communication terminal, if the user has a plurality of callable numbers, such as a government office and a company, and wants to call in a place with a large amount of calls, the dialing function is performed after entering several available telephone numbers simultaneously. If you do not automatically call the phone number is selected to form a call link, thereby relieving the inconvenience of attempting an outgoing call while re-entering the phone number.
