Description

Mobile Telecommunication Terminal Capable of Searching and Storing Sender's and Receiver's Telephone Number and Control Method Thereof}

The present invention relates to a mobile communication terminal having an efficient retrieval and storage function of incoming and outgoing telephone numbers and a control method thereof. More specifically, the mobile communication terminal and its control provide a function of classifying and displaying outgoing and incoming phone numbers stored in the memory of the mobile communication terminal according to various criteria and storing the necessary phone numbers individually and collectively. It is about a method.

As is well known, with the recent rapid development of electronic engineering and communication engineering, mobile communication terminals have various functions. That is, with the rapid development of wireless communication and data processing technology, people can use not only voice calls but also wireless Internet access, video communication and video message transmission using mobile communication terminals. In addition, due to the rapid dissemination of mobile communication terminals, mobile communication terminals are becoming an essential means of communication in modern life, such as a considerable amount of contact generated through human communication.

Conventionally, a mobile communication terminal knows that even if a call connection attempt is made to a mobile communication terminal and the call connection is not successful until a predetermined time passes and the call connection attempt is completed, the user even knows that a call connection attempt is made to his mobile terminal. Could not. That is, the conventional mobile communication terminal did not provide any information to the user regarding the call connection attempt when the call connection attempt failed.

In order to compensate for this disadvantage, when a call connection attempt fails, the mobile communication terminal simply provides a service for informing that there has been a call connection attempt. For example, when five attempts to connect a call fail, a phrase such as “5 missed calls” is displayed on the mobile communication terminal to inform the user that there have been five call failures.

However, the service that provides only the fragmentary information that there have been several call connection failures does not provide any information about the caller. Therefore, the user can know how many times the call connection attempt has not been received through the mobile terminal, but can not determine who the call is from, so the question of the caller is amplified and severely affects daily life. In some cases.

Therefore, in order to solve the drawbacks caused by the conventional mobile communication service does not provide any information of the caller has been recently provided caller identification service (CID: Caller Identification). Caller ID display service is a service that displays the caller's telephone number and the time the call was received on the called party's mobile terminal or display terminal before the call is initiated. This caller ID service is a new service of telephone network that combines switching technology, terminal technology, and transmission technology, and enables user control of calling and incoming calls, and the caller's phone number or name is before or during a call. Displayed on the LCD (Liquid Crystal Display) screen of the mobile terminal, the receiver can select the call connection. In addition, since the caller's phone number is displayed, it can be protected from phone violence such as violence and mischief calls, and can check all of the missed reception details.

On the other hand, outgoing histories, such as the telephone number of the calling telephone and the caller's information (name or alias) associated with the call connection attempt performed by the called party's mobile communication terminal, may be up to a predetermined number (for example, about 10 to 50). It is stored in the memory of the terminal. Similarly, the incoming call history such as the telephone number of the called phone and the information of the called party, which the user attempted to make a call is also stored in the mobile communication terminal up to a predetermined number. Therefore, the user can retrieve the incoming call history and the outgoing call history stored in his mobile communication terminal at any time through key manipulation and separately store it in the telephone number memory area. In this way, the incoming and outgoing history temporarily stored in the mobile communication terminal is deleted from the memory one by one in order from the old data when the preset number exceeds a predetermined number.

On the other hand, the incoming and outgoing history stored in the mobile communication terminal separately stored the incoming and outgoing history according to the type of mobile communication terminal and then display by the incoming or outgoing history, or distinguish the incoming and outgoing history It is provided in two forms that can be stored and displayed at once. Therefore, when a user wants to find a desired phone number in a normal incoming or outgoing history, a problem of searching for a incoming or outgoing history is usually the worst case. have. This can be a arduous task that requires a lot of time and effort for the user.

Moreover, the user must invest a lot of time and effort to retrieve dozens of incoming and outgoing histories currently provided by the mobile terminal, and the mobile terminal that provides hundreds of incoming and outgoing histories in the future is prevalent. If the user's discomfort associated with the incoming or outgoing history search will be amplified.

In addition, the current user should store the phone numbers temporarily included in the incoming or outgoing history and stored temporarily in the mobile communication terminal as a phone number memory area, one at a time. Such a function also requires a lot of effort and time for the user when there are many phone numbers to be kept separately in the phone number memory area.

In order to solve the above problems, the present invention provides a function for classifying and displaying outgoing and incoming phone numbers stored in the memory of the mobile communication terminal according to various criteria, and storing necessary telephone numbers individually and collectively. An object of the present invention is to provide a mobile communication terminal and a control method thereof.

1 is a block diagram briefly illustrating an internal configuration of a mobile communication terminal 100 according to a preferred embodiment of the present invention.

Mobile communication terminal 100 according to an embodiment of the present invention is a program memory 102, key input unit 104, LCD display unit 106, data storage unit 108, mode state storage unit 110, subscriber information A subscriber identity module (SIM) 112, a microprocessor 114, a digital signal processor (DSP) 116, a baseband converter 118, a speaker 120, a microphone 122, an antenna 124, an RF signal processor 126, and the like. In addition, the mobile communication terminal 100 according to a preferred embodiment of the present invention includes a variety of mobile phones, PDA (PDA) and the like.

Referring to FIG. 1, the program memory 302 stores protocol software for implementing functions of the terminal itself and processing messages transmitted and received with the network, and a predetermined call history management program according to an embodiment of the present invention is stored. have. The call reception history management program performs a function of classifying a call history and a call history stored temporarily in the mobile communication terminal 100 according to a classification criterion input by the user through the key input unit 104. The call history management program according to an embodiment of the present invention may be coded using C ⁺⁺ or JAVA, which is an object-oriented language. The classification criteria according to the embodiment of the present invention include all, ascending, descending, time, new, moving, general and the like, which will be described in detail with reference to FIG. 2.

The key input unit 104 is provided with a plurality of key buttons for inputting numbers such as telephone numbers. Such key buttons typically include 12 numeric keys (0 to 9, *,,), multiple function keys, multiple cursor movement keys, and the like. Accordingly, the user can search for and store a desired phone number by selecting a call log or call log by operating a numeric key, a function key, a cursor movement key, and the like provided in the key input unit 104.

The LCD display unit 106 generally displays an operation state of the mobile communication terminal 100 including a state of use of a battery, a reception strength of radio waves, a date and a time. In addition, according to an embodiment of the present invention, the LCD display unit 106 displays various sorting criteria and incoming or outgoing histories according to the selected sorting criteria possible on one screen.

The data storage unit 108 generally serves as a data buffer when executing an operation program of the mobile communication terminal 100 and temporarily stores data input by the key input unit 104 or performs mobile communication from the outside. The terminal 100 stores data such as a text or an image received by the terminal 100. In addition, according to an embodiment of the present invention, the data storage unit 108 temporarily stores the incoming and outgoing details of the mobile communication terminal 100 up to a preset number, and the incoming or outgoing history exceeds the preset number. First, they are deleted one by one in the order in which they were stored. This is the same principle as the Queue structure, which is the first In First Out (FIFO) data structure that is inserted first.

The mode state storage unit 110 stores the current operation mode of the mobile communication terminal 100 selected by the key input unit 104 as a state flag (0, 1, 2, ...). That is, the microprocessor 114 sets a unique state flag for each mode to distinguish whether the mobile communication terminal 100 is an incoming mode, an outgoing mode, an incoming / outgoing call history search mode, a storage mode, or a call mode. The mode state storage unit 110 is updated by the allocation.

The subscriber information storage unit 112 stores registration information of a subscriber (= user). The subscriber information storage unit 112 is also called a SIM card because it is inserted into a slot in the form of a card, and performs an interface function between the mobile communication terminal 100 and a communication network. The SIM card stores a mobile identification number (MIN), a personal security key, and various data (general wired / wireless telephone number, counterpart information, etc.) necessary for the operation of the mobile communication terminal 100. You can remove the SIM card and attach it to another terminal to perform voice and data communications. That is, when the power of the mobile communication terminal 100 is turned on, the mobile communication terminal 100 transmits and receives all the information in the SIM card to the mobile communication network. do.

The microprocessor 114 controls the overall operation of the mobile communication terminal 100 based on the state flag stored in the mode state storage unit 110. In particular, when the search mode of the incoming / outgoing call history is selected by the key input unit 104, the microprocessor 114 drives the incoming / outgoing call classification program stored in the program memory 102 and classifies and displays the incoming / outgoing call history according to the input classification criteria. Do the work. To this end, the microprocessor 114 generates a search mode control signal and transmits the search mode control signal to the mode state storage unit 110 when the search mode of the incoming / outgoing history is selected, and transmits the corresponding classification criterion key value to the incoming / outgoing classification program when the classification criteria are selected. .

In addition, the microprocessor 114 performs a call function by switching to the call mode when the call button is selected while the cursor is located at a specific call item among the search modes of the call history, and performs the call function when the save button is selected. Stored in the telephone number area of the information storage unit 112. Accordingly, the microprocessor 114 transmits the digital data for performing this function to the baseband converter 118 (TX DATA).

The DSP 116 is a digital signal processing processor that codes or decodes a speech signal, functions as an equalizer for multipath noise cancellation, and performs an acoustic data processing function. Also, the DSP 116 exchanges voice data SPEECH with the baseband converter 118 and receives digital data RX DATA from the baseband converter 118.

The baseband converter 1318 converts signals transmitted and received between the RF signal processor 126 and the DSP 116, the speaker 120, and the microphone 122 into baseband signals, and converts the digital-to-analog converter and the analog. -Performs functions such as digital conversion. The speaker 120 outputs an audio signal output from the baseband converter 118 as an audible sound, and the microphone 122 converts a user's voice input into an electrical signal.

In addition, the baseband converter 118 transmits the transmission data (TXIQ) to the RF signal processor 126, and controls the power (POWER) of the RF signal processor 126 or automatically controls the corresponding gain (AGC). . In addition, the RF signal processor 126 receives the received signal RXIQ.

The antenna 124 transmits and receives a radio signal, and the RF signal processor 126 demodulates and amplifies an RF signal received by the antenna 124 and modulates a transmission signal applied from the baseband converter 118 to perform an RF signal processor. Output to (126).

The RF signal processing unit 126 performs a modulation process of loading a signal transmitted from the microprocessor 114 to a high frequency signal and transmits the signal to the radio space through the antenna 124 or demodulates the radio signal received through the antenna 124. To deliver to the microprocessor 114.

2 is an exemplary screen diagram showing incoming, outgoing and call details of a mobile communication terminal 100 classified according to various classification criteria according to an embodiment of the present invention.

As can be seen from Figure 2, the mobile communication terminal 100 according to an embodiment of the present invention is 'all', 'save', 'up', 'down', 'time' as the classification criteria of incoming, outgoing and call history ',' Reverse, 'general', 'move', 'new', 'foreign'. Here, when the classification criteria are defined one by one, 'all' is an item which randomly displays all the history stored in the mobile communication terminal 100, and 'save' is one or a batch of all or part of the displayed phone numbers. This item is stored in the telephone number storage area of the subscriber information storage 112 described with reference to FIG. 1. In addition, 'ascending' is an item for classifying the history stored in the mobile communication terminal 100 in ascending order, and 'Descending' is a descending order in descending order of the history stored in the mobile communication terminal 100. This item is classified as.

Here, the ascending order is to classify the history in the order of 'a'-> 'ㄴ'-> ...-> 'ㅎ' of the Hangul consonants, the descending order is to classify the history in reverse. In addition, the ascending and descending order applied to the embodiment of the present invention may be used in the opposite meaning. On the other hand, when the history according to the embodiment of the present invention includes numbers other than Korean, images, and foreign languages (particularly English), the ascending or descending order is used for coding an incoming / outgoing call history classification program mounted in the mobile communication terminal 100. Will be decided by. That is, when manufacturing the mobile communication terminal 100, the ascending order may be determined in the order of image-> number-> Korean-> foreign language, or, conversely, in the order of foreign language-> Korean-> number-> image. .

Meanwhile, 'time' is an item for sorting the history stored in the mobile communication terminal 100 in chronological order, and 'reverse order' is an item for sorting the history as opposed to the 'time' item. In addition, 'general' is an item for classifying only general wired and wireless telephone numbers among the histories stored in the mobile communication terminal 100, and 'moving' is a mobile communication terminal among the histories stored in the mobile communication terminal 100. (100) (phone, PD, etc.) is a category that separates only the phone number.

Finally, 'new' classifies only new phone numbers that are not stored in the phone number area of the subscriber information storage unit 112 of the mobile communication terminal 100 among the history stored in the mobile communication terminal 100 separately. The item 'foreign' is an item that classifies only domestic phone numbers or phone numbers used in foreign countries other than MIN among the records stored in the mobile communication terminal 100. In particular, the 'foreign' item may be used as a useful function since IMT-2000-only terminal is commercialized and a global roaming service is provided so that phone calls with foreign countries may be frequent.

Looking at the example screen of Figure 2A, it can be seen that the incoming history is sorted in ascending order. That is, it can be seen that the ascending order applied to FIG. 2A is numbers-> Korean-> foreign language, and the numbers are also in ascending order (0, 1, 2 ..).

The example screen of FIG. 2B classifies and displays only MIN among the call histories. Of course, although the MIN used by all domestic mobile communication operators is displayed at once on the example screen of FIG. 2B, a function of classifying and displaying the calling history for each mobile communication provider may be provided. That is, when the 'move' item is selected in the example screen of FIG. 2B, a selection screen of each mobile operator is displayed in the next step (for example, 1. SKT (011, 017) and 2. KTF (016, 018). LGT (019)), when a specific mobile communication provider is selected, only the corresponding MIN may be classified and displayed. Similarly, the 'general' item may also provide a function of reclassifying and displaying the history for each area code (02, 031, 051, 062, etc.).

The example screen of FIG. 2C classifies and displays only new telephone numbers which are not stored in the subscriber information storage 112 of the mobile communication terminal 100 among the call histories. To this end, when the key value of the 'new' item is input through the key input unit 104, the microprocessor 114 drives the incoming / outgoing classification program stored in the program memory 102 and stored in the subscriber information storage 112. All phone numbers and incoming / outgoing call history stored temporarily in the data storage unit 108 are compared to display only the new phone number through the LCD display unit 106.

Meanwhile, the technical idea of the present invention may be applied to other classification criteria other than the classification criteria of eight kinds of incoming / outgoing histories illustrated in FIG. 2.

3 is a flowchart illustrating a process of searching an incoming / outgoing call history using the mobile communication terminal 100 according to an exemplary embodiment of the present invention.

A user who wants to check one or more of the incoming history, the outgoing history, and the call history by using the mobile communication terminal 100 according to the embodiment described in FIG. 1 is the key input unit 104 of the mobile communication terminal 100. An incoming / outgoing call history search function is selected by operating a predetermined function key provided at step S300.

The microprocessor 114 that receives the key value of the incoming / outgoing history search through the key input unit 104 sets the flag of the mode state storage unit 110 to the search mode value and changes to the search mode (S302).

When the search mode is changed, the microprocessor 114 drives the incoming / outgoing call history classification program stored in the program memory 102 (S304). When the call origination history classification program is driven in the mobile communication terminal 100, the call history log menu screen is displayed on the LCD display 106.

One history mode key value desired to be searched among the incoming history mode, the outgoing history mode, and the call history mode of the incoming / outgoing history menu screen displayed on the LCD display unit 106 is input by the user through the key input unit 104 (S305). .

One sorting criteria key value desired to be searched on the specific history mode screen on which various sorting criteria items are displayed through the LCD display unit 106 is input through the key input unit 104 by the user (S306).

The microprocessor 114 that receives the specific classification key value through the key input unit 104 passes the classification reference key value received to the call origination history classification program in operation, and the call origination classification program uses the received classification reference key value. The incoming / outgoing call history stored in the storage unit 108 is classified (S308).

The sorted history list is displayed on the LCD display unit 106 under the control of the microprocessor 114 (S310). Accordingly, the user searches the history list displayed on the LCD display 106 by using a cursor movement key or the like provided in the key input unit 104. Of course, the user may separately store or delete a specific history item while searching the history list.

While searching is performed by the user on the sorted history list screen, the microprocessor 114 continuously checks whether another sorting reference key value is input through the key input unit 104 (S312).

If it is determined in step S312 that another classification criterion key value is input, the microprocessor 114 proceeds to step S308 to perform classification work on the history list again according to the input classification criterion. Otherwise, if it is determined in step S312 that no other classification criteria key value is input, the microprocessor 114 continues the search operation of the sorted history list (S314).

Similarly, while searching is performed by the user on the sorted history list screen, the microprocessor 114 continuously checks whether a search mode release key value is input from the key input unit 104 (S316).

If it is determined that the search mode release key value is input in step S316, the microprocessor 114 releases the call origin history search mode of the mobile communication terminal 100 (S318). Here, the release of the incoming call history search mode refers to a case where the operation mode of the mobile communication terminal 100 is switched to a mode other than the incoming call history search mode (standby mode, voice call mode, data communication mode, etc.). When the call origination history search mode is released by the user in step S316, the microprocessor 114 changes the flag value of the call history history mode of the mode state storage unit 110 to the flag value of the mode to be switched.

Otherwise, if it is determined in step S316 that the search mode release key value is not input, the microprocessor 114 proceeds to step S314 to continue the search operation of the sorted history list.

The above description is merely illustrative of the present invention, and those skilled in the art to which the present invention pertains may various modifications without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed herein are not intended to limit the present invention but to describe the present invention, and the spirit and scope of the present invention are not limited by these embodiments. It is intended that the scope of the invention be interpreted by the following claims, and that all descriptions within the scope equivalent thereto shall be construed as being included in the scope of the present invention.

As described above, in order to search the incoming and outgoing history using a conventional mobile communication terminal takes a lot of time and effort, but the search itself may be almost impossible, according to the present invention conveniently and quickly the desired incoming and outgoing history by using various incoming and outgoing history search mode You can search for

In addition, the existing mobile communication terminal provided only a function of storing a call number in the search mode one at a time in a search mode, but according to the present invention, a user can collectively store several phone numbers.
