How to dial a mobile cordless phone

The present invention relates to a dialing method of a mobile radio telephone, and more particularly, to a short dialing method using a unique number of a subscriber.

1 is a diagram showing the configuration of a general mobile radiotelephone. Looking at the configuration of the mobile radio telephone as described above, the control unit 111 controls the overall operation of the mobile radio telephone. The first memory 112 stores program and initial service data. The first memory 112 may be configured as an EEPROM. The second memory 113 temporarily stores data generated during operation of the mobile radio telephone. The second memory 113 may be configured as a RAM. The input unit 114 may generate key data for performing various modes and dialing of the mobile radio telephone, and outputs the input signal generated as described above to the controller 111. The input unit 114 may include a keypad and a mode switch. The display unit 123 displays data and state information generated during program execution under the control of the control unit 111. The display unit 123 includes a liquid crystal display (LCD), an LED, and the like.

The logic unit 115 transmits / receives data for controlling the operation of the mobile radio telephone with the control unit 111. The logic unit 115 outputs control data for controlling the operation of each unit of the mobile radio telephone. The data processor 116 communicates with the controller 111. The data processor 116 processes the received data RXD output from the RF receiver 120 and applies the signal to the controller 111, and processes the transmitted data TXD output from the controller 111 and outputs the signal to the RF transmitter 121. The data processor 116 may use a digital signal processor.

The duplexer 122 is connected to an antenna to separate a transmission RF signal and a reception RF signal. The RF receiver 120 is connected to the duplexer 122 and outputs the frequency down-converted and demodulated RF signal. The received audio signal RXA output from the RF receiver 120 is output to the audio receiver 117, and the received data RXD is output to the data processor 116. The audio receiver 117 inputs an audio signal output from the RF receiver 117 to reproduce the audio signal. The audio transmitter 118 inputs and processes an audio signal. The RF transmitter 121 inputs the transmission audio signal TXA output from the audio transmitter 118 and the transmission data TXD output from the data processor 116, modulates the frequency in a transmission form, and converts the frequency up-converted into the duplexer 122. The frequency synthesizer 119 generates a frequency synthesized signal for allocating the reception channel of the RF receiver 120 and the transmission channel of the RF transmitter 121 by the control data of the logic unit 115.

When attempting an outgoing call to a general wired subscriber in the mobile radio telephone having the above configuration, the dialing should dial the station number and the unique number including the area code to which the called subscriber is subscribed. At this time, the area code is 2 to 3, and the station code and unique number are 6 to 8. Therefore, in the outgoing call calling the general subscriber, the subscriber of the mobile radio telephone must dial up to 11 to 9 numbers. In addition, even when calling a mobile radio telephone subscriber, ten to eleven numbers consisting of three service provider identification numbers, a station number and a unique number must be dialed.

Therefore, in order to simplify the above dialing operation during an outgoing call, a shortened dialing method is generally used. For the speed dialing, first, a phone number of subscribers frequently called in the second memory 113 is stored to create a speed dial number table, and dialed a speed dial number which is an index address of a corresponding speed dial number table during an outgoing call. Ring. Then, the controller 111 accesses and dials the telephone number corresponding to the corresponding speed dial number in the speed dial number table of the second memory 113.

However, such a speed dialing method is cumbersome for a user to memorize speed dial numbers corresponding to phone numbers registered in a speed dial number table. In addition, if an incorrect dialing number is incorrectly entered during an outgoing call, a call path may be formed with an unwanted subscriber, thereby reducing the efficiency of the call.

Accordingly, an object of the present invention is to provide a method for easily performing a speed dialing function during an outgoing call in a mobile radio telephone.

Another object of the present invention is to provide a method for storing telephone numbers according to a unique number in a mobile radio telephone and automatically dialing a corresponding subscriber's telephone number when a unique number is received in a call mode.

In order to achieve the objects of the present invention, a dialing method of a mobile radio telephone having a speed dial number table for storing a telephone number consisting of an area code, a station number, and a subscriber's unique number to correspond to the unique number, Temporarily storing a unique number input for receiving; searching for a telephone number corresponding to the received unique number in the speed dial number table upon receiving a dialing key; and accessing and displaying the found telephone number; This is done by dialing.

1 is a diagram showing the configuration of a typical mobile radiotelephone.

2 is a diagram illustrating a procedure for servicing dialing in a mobile radio telephone according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same parts in the figures represent the same reference signs wherever possible.

The configuration of the mobile radiotelephone carrying out the present invention has the same configuration as that in FIG. 1, and the same reference numerals are used.

When performing the dialing function with the speed dial table as described above, the user must remember whose phone number is stored in the speed dial number corresponding to which index address in order to use this function. do. However, if there are many registered telephone numbers, it is difficult to distinguish whose telephone number is registered in which speed dial number. In this case, instead of remembering the speed dial number, it may be more likely to remember the telephone number. Therefore, an embodiment of the present invention proposes a method for performing a speed dial function using a subscriber number.

In general, when dialing using a mobile radio telephone, dial the area code + station number + subscriber numbers, for example, assuming that the subscriber's telephone number is 02-745-0084, 02 is the area code. 745 is the subscriber's station number, and 0084 is the subscriber's unique number. In addition, even when calling a mobile wireless telephone subscriber using a mobile wireless telephone, the service provider identification number + station number + subscriber's unique numbers are dialed. For example, assuming that the telephone number of the mobile radio telephone is 011-222-3333, 011 is a service provider identification number, 222 is a station number, and 3333 is a subscriber's unique number. In the present invention, the short dialing is performed by using the unique number of the subscriber. Typically, the unique number consists of four digits.

In order to dial out a unique number and attempt an outgoing call, the mobile radiotelephone must be provided with a speed dial number table in the internal memory 112. And while performing the registration mode, the subscriber's telephone numbers for dialing with a unique number should be registered. That is, the area code if you are a regular telephone subscriber. Telephone numbers consisting of station number and unique number should be registered. If you are a mobile wireless telephone subscriber, you should register service provider identification number, telephone number consisting of station number and unique number. The index of the registered table is designated to correspond to the unique number. In the embodiment of the present invention, it is assumed that the unique number is four digits.

2 is a flowchart of a short dialing method of a mobile radio telephone according to the present invention.

When attempting an outgoing call first, the subscriber of the mobile radiotelephone dials the unique number or dials all of the subscriber's telephone numbers. Then, the control unit 111 which sequentially inputs the telephone numbers generated by the input unit 114 temporarily stores them in the buffer area of the second memory 113. In this state, when a SEND key is received at the input unit 114, the control unit 111 detects a key signal corresponding to the transmission key in step 211, and the number of digits of the phone numbers stored in the second memory 113 in step 213. Check it. If the number of phone numbers stored in the second memory 113 is greater than the number of unique numbers, that is, more than four digits, the process proceeds to step 225 to perform a general dialing operation.

However, if the number of phone numbers stored in the second memory 113 is less than or equal to the number of subscribers in step 213, the speed dial number table of the first memory 112 is searched for in step 215. That is, in step 215, the controller 111 sequentially compares the inputted unique number with the unique numbers of the speed dial number table of the first memory 112 and searches whether the same unique number exists. At this time, if it is determined in step 217 that the same unique number as the inputted unique number is not registered in the speed dial number table of the first memory 112, the controller 111 proceeds to step 225 to perform a general dialing operation. To perform. In this case, the entered number is dialed as it is. In this case, the control unit 111 may ignore the input telephone number and display the error state on the display unit 123.

However, if it is determined that the same unique number as the unique number input in step 217 is registered on the speed dial number table, the flow proceeds to step 219 to determine whether there is one registered unique number. In this case, if the same unique number is 1, the process proceeds to step 221 to display a phone number (area code, area code, subscriber number) corresponding to the corresponding code on the display unit 123, and performs dialing. After the dialing ends, the mobile radio telephone transitions to the call mode when the called subscriber answers.

However, if there are two or more unique numbers registered as the unique numbers input in step 219, the control unit 111 proceeds to step 223 to control the display unit 123 to sequentially display the phone numbers having the same unique number, and to select a user. Wait. When the selection key is input through the input unit 114 while the phone numbers are sequentially displayed as described above, the control unit 111 accesses the phone number currently displayed on the display unit 123. Thereafter, the process proceeds to step 221 to display a telephone number (area code, area code, unique number) corresponding to the unique number corresponding to the display unit 123, and performs dialing. After the dialing ends, the mobile radio telephone transitions to the call mode when the called party answers.

As described above, when performing a speed dial function in a mobile wireless telephone having a speed dial number table, if a user inputs a unique number of the subscriber among the telephone numbers, the mobile wireless telephone is unique to the subscriber in the speed dial number table. The same phone number as the number can be accessed to dial automatically.
