Description

METHODO FOR DISPLAYING THE CALLING TIME ON MEMORY REDIAL LIST IN TELEPHONE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory redial control method in a telephone, and more particularly, to a method of storing a transmission time and displaying the redial list.

The memory redial or call history function saves the outgoing number or the number connected to the call channel after the outgoing call when the user dials the phone number in a specific memory area. This function allows you to call out the numbers in the order you called them most recently. The number of calling numbers that can be stored in this way depends on the memory capacity of the mobile radio telephone.

However, this memory redial function has a very limited scope of providing related information. That is, the terminal displays only the number that the user called and the stored name such as the number. In fact, in the case of a digital telephone, even when the telephone is displaying the current time, when the memory redial display is performed, it is not known what time and number of minutes the user dialed.

It is therefore an object of the present invention to provide a method for enabling the display of a call time in a redial list in a telephone.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, if it is determined that detailed descriptions of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram showing the configuration of a mobile radiotelephone to which the present invention is applied.

The controller 111 controls overall operations of the mobile radio telephone. The first memory 112 stores a control program and initial service data. The first memory 112 may be configured as a flash memory. The second memory 113 temporarily stores data generated during the operation of the mobile radio telephone, that is, the calling number and the calling time. The second memory 113 may be configured as a RAM. The third memory 113-1 is a memory for storing important variables required for the mobile radio telephone to operate or a telephone number input by the user, and may be configured as an EEPROM. The key input unit 114 generates key data for performing various modes and dialing of the mobile radio telephone and outputs the generated key data to the control unit 111. The logic unit 115 transmits and 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 part 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. The data processor 116 processes the transmitted data RXD 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 received RF signal by frequency conversion and demodulation. 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 transmission type, and outputs the same to 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. The display unit 123 displays the calling number and the calling time under the control of the controller 111. The controller 111 includes a predetermined timer.

2A to 2C are flowcharts illustrating a memory redial control process of a mobile wireless telephone according to an exemplary embodiment of the present invention.

Referring to FIG. 2A, when power is supplied to a mobile wireless telephone using a power key, the control unit 111 starts an operation and performs an initial operation in step 1. FIG. That is, the settings of the analog / digital system and the variable values necessary for the mobile radio telephone to operate are initialized. In step 2, it is checked whether the pilot channel is acquired in the pilot channel acquisition state. If the pilot channel is not acquired within the designated time, the process returns to step 1 and performs the initialization. In other words, if the pilot channel is not acquired in step 2, the process proceeds to step 3, and if the pilot channel acquisition time-out is not checked, the process returns to step 2 if it has not timed out. On the other hand, if a pilot channel is acquired within a specified time, the UE transitions to a synchronization channel reception state in step 4 and checks whether a synchronization channel message is received. If a synchronization channel message is received within a specified time in the synchronization channel reception state, the process proceeds to step 6 to set a system time. That is, in step 6, the system time and various variable values are obtained and set from the received sync channel message. On the other hand, if the synchronization channel message is not received within the designated time, the process returns to step 1 again and performs the initialization operation. In other words, if the synchronization channel message is not obtained in step 4, the process proceeds to step 5 and checks whether or not the synchronization channel message reception timeout has been timed out, and returns to step 4 if it has not timed out. In step 7, the controller 111 initializes the necessary variables in the idle state and then switches to the idle state. In this state, it monitors the paging channel, checks whether the user makes an outgoing call or uses various other functions, and takes action accordingly. It also increments the time if the time is set by acquiring the system time or checking whether the user time is set. In step 8, the control unit 111 scans the key input unit 145 to check whether there is a key input. In step 9, when an input of a numeric key is detected, the controller 10 proceeds to step 10 and controls the display unit 123 to display the input number and stores the number in a buffer.

Referring to FIG. 2B, when an input of a calling key is detected in step 11 of FIG. 1, the control unit 111 checks whether a call is connected in step 13 after controlling the dialing of the input number. However, if the number stored in the memory redial buffer covers all of the telephone numbers that were once called, the calling telephone number and the current time at the time of transmission are stored in the memory redial buffer before switching to step 13. In step 13, if a signal indicating that a call is connected is transmitted from the main call processing state, the process proceeds to step 14 to switch to a conversation initial state. In this call initial state, the variable values required in the call state are initialized. In addition, if the phone number stored in the memory redial buffer is implemented in such a manner as to store only the numbers to which the call is connected, that is, a successful call, in this state, the calling phone number and the current time at the time of the call are stored in the memory redial buffer. In step 15, the user enters a call state and checks actions that the user can take and executes the procedures accordingly. In other words, if the key input is not detected in step 16 and the key input is not detected, the process returns to the step 15 above. On the other hand, if there is a key input, it is checked in step 17 whether the user inputs the END key. In this case, if the end key is input, the process returns to the call termination state in step 18 to store the talk time and the total talk time, and then returns to the above-described step 7. If it is not the end key in step 17, the process proceeds to step 19 to perform a corresponding key processing operation and then returns to step 15 to maintain a call state.

Referring to FIG. 2C, if an input of a recall key is detected in step 12 of FIG. 1, the control unit 111 sets a phone number recall state in step 20. In this state, the memory redial and the stored telephone number can be confirmed. In step 21, the controller 111 scans the key input unit 145 to check whether there is any key input. If there is a key input as a result of the check, it proceeds to step 22 and checks whether the input key is a memory address for confirming the stored telephone number. In the case of inputting the check result, the process proceeds to step 23 and the phone number stored in the address is read and transmitted to the display unit 123 so that the display unit 123 displays it. If the name is stored together, the name is also read and transmitted. Let's do it. After displaying the contents of the address designated by the user, proceed to step 40 to check whether there is a key input again. If there is a key input, the input key is an exit key, a recall key, or a numeric key in steps 41 to 43. Determining which one of the control and to perform the corresponding operation according to the determination result.

If it is determined in step 22 that the address is not input, the process proceeds to step 24 and checks whether the memory redial key is input. The storage redial key is a key for requesting the display when the user wants to see the storage redial list. Meanwhile, steps 12 and 20 to 23 described above are merely a process for searching for a desired phone number among contents created by the user in advance, such as a phone book, and are not related to the gist of the present invention. Therefore, step 23 may not have the same order as in the present embodiment, but may have a sequence immediately following step 11 described above.

If the memory redial key is not input, the process proceeds to step 25 and checks whether it is the end key. On the other hand, if it is determined that the memory redial key is input, the flow advances to step 26 to switch to the memory redial display state. When the memory redial display state is entered, the mobile wireless telephone must display the most recently called telephone number, so the state changes with the last index of the contents in the memory redial buffer. In step 27, the control unit 111 displays the memory redial address. The display unit 123 causes the display unit 123 to display the outgoing telephone number and the outgoing time from the memory redial buffer corresponding to the address and transmits the outgoing telephone number and the outgoing time to the display unit 123. In addition, if the name is stored together, the name is also displayed by reading it. The outgoing time may be a current time input when the outgoing key is detected in step 14 according to the implementation of the memory redial function, or a current time input when the call is switched to step 14 after the call is connected in step 13 described above. It may be.

After all the information on the memory redial is displayed, it is checked in step 28 whether any key is pressed. If it detects a key input, it checks whether the input key is an end key in step 29, and if it is an end key, returns to step 7 described above. If it is not the end key, check whether it is a memory redial scroll key in step 30, and if it is a scroll key, specify the address of another memory redial number in step 31 and return to step 27 to display the memory redial for the number. .

Meanwhile, in the detailed description of the present invention, a specific embodiment has been described, but various modifications are possible without departing from the scope of the present invention. In other words, although the mobile wireless telephone has been described in the present embodiment, any type of telephone having a clock function and a display function can be used. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention displays the telephone number and the time of the call, which the user has sent, so that the user can clearly know when the user makes the call even though the user does not have to pay attention.
