Description

Method for changing send / receive blocking mode and mobile phone embodying the same {Method for changing send / receive stop mode and Mobile phone embodying the same}

The present invention relates to a method for switching a transmission / reception blocking mode and a mobile phone implementing the same, and more particularly, to block a transmission / reception mode and to calculate a time difference when a user selects a country of a travel destination. The present invention relates to a mobile phone and a method for providing such a method.

In general, a mobile communication phone has a main function of exchanging voice with a counterpart by performing a phone call function. However, wireless communication has developed and mobile phones have provided additional services, according to the name, to the level of necessities essential for the general public. Examples of this may include an automatic answering function, an alarming function, a payment function, an internet access function, and a clock indicating time. In other words, users can carry only one mobile phone and use it as a means of payment, transportation card, scheduling, etc. without the help of other additional devices.

Among them, the clock function is frequently used by users. When a general mobile communication terminal is initially applied, that is, when the mobile communication terminal is powered on, the mobile communication terminal reads the necessary system information from the ROM in the memory. After setting, synchronize with the system and receive the necessary system information from the base station in the area. This necessary system information also includes data for initializing the time. Therefore, the mobile communication terminal receives information about time through an initialization process of booting and receives necessary system information and provides the user with the time information.

When the initialization process is completed, the mobile communication mobile terminal is switched to an idle state. That is, the mobile communication terminal receives all system information to complete normal operation, and then continuously receives a paging channel (a forward code channel used for calling the mobile station from the base station and transmitting control information). Say.

Alternatively, there is a method of determining an initial time by receiving time information from a global positioning system (GPS) by a mobile communication terminal without receiving time information from the mobile station. This is to receive the initial time information from the satellite positioning system to operate by a power source inside the mobile communication terminal to provide the correct time to the user.

In the case of using the above-described method, the clock of the mobile communication terminal is operated by a power input from the battery, and thus has a disadvantage of fast exhaustion of the battery. Because, when going abroad with a mobile communication terminal, the mobile communication terminal performs synchronization to update the system information of the mobile station or satellite positioning system and the mobile communication terminal. In this synchronization process, since the mobile communication terminal periodically receives the synchronization signal from the mobile station or the satellite positioning system, the battery is easily exhausted.

In addition, there is a drawback that the user can not use the functions of the mobile communication terminal when going abroad when the battery is exhausted. This is because the mobile communication terminal updates the system information through synchronization. Since the synchronization does not proceed, the mobile communication terminal is only a useless machine. That is, only the role of the phone book is possible.

The present invention has been proposed to overcome the above-mentioned disadvantages, the user of the mobile phone can continue to use the clock function, calculator, alarm, schedule, etc. by changing to the transmission and reception blocking mode when the user does not receive a repeater signal due to overseas travel, etc. The purpose is to make it.

Still another object of the present invention is to provide a mobile phone such that the basic time-related functions are not interrupted even in a business trip.

The present invention provides a transmission and reception blocking mode switching method and a mobile phone implementing the same. For this purpose, the mobile phone does not receive the synchronization signal from the repeater and does not supply power to the wireless circuit as it switches to the transmission / reception block mode, and it reads the time information from the timer and calculates the time information of the traveled country selected by the user. It consists of a control unit for calculating, a numeric key button and a general button used for input and output, a keypad for transmitting a user's instruction to the control unit, various menu screens selected by the user of the mobile phone according to the control of the control unit and A first display unit displaying an execution screen and a result screen according to the present invention, a second display unit displaying a digital clock under the control of the controller as an auxiliary LCD, and a function of checking and calculating time using a clock pulse generated by the controller The timer unit and the user to change to the transmission and reception blocking mode The memory unit stores a program that reads time information from a timer and performs a calculation of the current time, and receives a telephone call or a short message sent by an external telephone through an antenna and transmits it to the controller and is stored in the memory unit. The wireless circuit unit performs the function of transmitting the data to the caller's telephone through the antenna, and processes the voice recorded through the microphone as data, transmits it to the controller, and processes the data received from the outside to receive analog voice through the speaker. A component such as an audio processor for outputting is provided. Through this, the mobile phone stops the transmission / reception mode and performs only a function related to the clock. Therefore, in addition to the functions in the mobile phone basically related to time, the user can conveniently utilize the information in the mobile phone when traveling.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an internal configuration diagram of a mobile phone for implementing the present invention.

In order to implement the present invention, a block diagram of a mobile phone includes a control unit 100, a keypad 110, a first display unit 120, a second display unit 130, a timer unit 140, and a memory unit 150. , The wireless circuit unit 160, the audio processor 170, and the like. Referring to the operation of each component in the mobile phone having such a structure as follows.

The control unit 100 controls all functions of the mobile phone. In the present invention, in particular, in addition to an operation for a general mobile communication call, the control unit 100 does not receive a synchronization signal from the repeater as the user switches to a transmission / reception block mode, Do not supply In addition, the time information is read from the timer unit to calculate the time information of the traveling country selected by the user to calculate the current time. In addition, the relevant function is loaded from the memory unit to execute the corresponding function.

The keypad 110 is composed of a selection button for creating and storing a short message in a mobile phone or selecting a menu, a numeric key button used as an input and an output, and a general button. It acts as an intermediary to send).

The first display unit 120 displays various menu screens selected by the user of the mobile phone, an execution screen, and a result screen according to the control of the controller 100. Therefore, the user of the mobile phone can see it and perform the desired function.

The second display unit 130 is an auxiliary LCD which can be seen in a folding type mobile phone and displays a digital clock under the control of the controller 100. Although the present invention has been described with a clamshell mobile phone, the present invention is not limited thereto, and is applicable to a bar type, a flip type, and a slider type model, which do not include an auxiliary CD. This is because it is possible to display the digital clock according to the present invention because the first display unit is provided in all types of mobile phones.

The timer 140 is responsible for checking and calculating time using a clock pulse generated from the controller. The timer unit may be configured as a control unit, or may be configured independently as in the present invention.

The memory unit 150 is usually composed of a flash memory, a random access memory (RAM), a read only memory (ROM), and the like. The dual flash memory stores the basic real time operating system (OS) and call processing software of the mobile phone. The variables and states of these programs are read from the RAM and operated. The ROM is composed of an electrically erasable programmable read only memory (EEPROM), and stores nonvolatile data that can be electrically erased or stored again and performs input / output according to a command of a controller. The data stored in these ROMs include NAM (number assignment module) parameters that can be used semi-permanently without being erased, and other data for storage (phone number and name, text message, video, etc.).

In addition, the flash memory is a non-volatile memory that has a high processing speed and data is preserved. When the software of the mobile phone is upgraded, new software is stored in this part.

In the present invention, as the user changes to the transmission and reception blocking mode, the program reads the time information from the timer and stores information such as a schedule, an alarm, and the like that perform a calculation of the current time.

The wireless circuit unit 160 receives a telephone call sent by an external portable communication terminal through an antenna and transmits it to the control unit 100 or transmits voice data in a storage unit through the antenna by processing of the control unit. It is responsible for transmitting to.

The audio processor 170 processes a voice recorded by a user of the mobile phone through a microphone as data and transmits it to the controller 100 or processes data received from the outside to output analog voice through a speaker. do.

2 is a flowchart illustrating a process of switching a transmission / reception mode according to the present invention.

When power is supplied to the cellular phone, the cellular phone reads the necessary system information from the ROM in the memory unit, sets it in RAM, synchronizes with the system, and receives the required system information from the base station in the area.

Accordingly, the initialization of the mobile phone refers to a state of booting the mobile phone and receiving necessary system information. The idle state, which proceeds after the initialization process, is performed by the mobile phone receiving all system information. After completion of the normal operation, it refers to a state of continuously receiving a paging channel (a forward code channel used for calling the mobile station from the base station and transmitting control information) (step S200).

In this standby mode, the cellular phone proceeds to the next state depending on whether the user has changed to the transmission / reception blocking mode (step S210).

If the change to the transmission / reception block mode by the user is not made, the cellular phone is in the standby mode for synchronizing with the repeater for a predetermined time.

The change to the transmission / reception blocking mode selects the electronic notebook from the menu list displayed by the menu button on the cellular phone. A screen example showing this is shown in FIG. 3.

On the contrary, when there is a change to the transmission / reception mode by the user, the cellular phone does not receive the synchronization signal from the repeater (step S220). The process proceeded by the user until the change to the above-mentioned transmission and reception mode is described as follows.

When the electronic notebook is selected, a screen for selecting the time of the world is displayed. A screen example showing this is shown in FIG. 4. In this screen example, the user can select the destination for which he / she is aiming. After the travel destination is selected through this process, the user can switch the cellular phone to the transmit / receive blocking mode.

The change to the transmit / receive blocking mode may be provided by the user with a dedicated button for the keypad of the mobile phone. Alternatively, it is possible to select a menu from a menu list displayed on the screen by selecting a menu button commonly used in a mobile phone without having a key button for a specific use on a keypad. The two methods illustrated above are only slightly different depending on the method of using a specific key button, and the functions or operations are the same.

When there is a change to the transmission / reception blocking mode, the cellular phone stops receiving the synchronization signal and stops supplying power to the radio circuit unit (step S230). In other words, by supplying power only to the part that can use the timer unit 140 and not supplying power to the remaining parts of the phone call, the battery of the cellular phone is maintained for a long time without charging.

After performing the above process, the cellular phone reads time information from the timer unit 140 (step S240). This is because the system information from the repeater is not synchronized, the purpose of reading the current time information to maintain the clock function in the mobile phone itself.

The mobile phone which read the current time information also reads the time information of the country selected by the user of the mobile phone and calculates the current time by the time of the business trip by applying the time difference between the current time and the business trip location (step S250).

The formula for calculating the current time of the business trip is as shown in Equation 1.

Time difference = Standard time of origin-Standard time of destination

Current time of travel destination = Current time + time difference

Here, standard time represents Greenwich mean time. In other words, a country or a province uses a common mean solar time, which means that Korea adopts a time that is nine hours ahead of world time.

When the current time of the destination is calculated, the cellular phone displays the first display unit and the second display unit (step S260).

In addition to the clock function, a program that reflects the time difference is configured and stored in the memory unit so that a function such as alarm, calculator, and schedule management, which are basically functions in a mobile phone, can be managed in a travel destination.

In the above, the present invention has been described with reference to the accompanying drawings and embodiments, but the present invention is not limited to the specific embodiments. And those skilled in the art will appreciate that many modifications and variations are possible without departing from the scope of the invention. Therefore, the protection scope of the present invention should be defined by the appended claims.

According to the present invention, when a user of a mobile phone does not receive a transmission / reception signal due to an overseas business trip, a digital clock, a calculator, an alarm, a schedule by changing only the role of a simple phonebook to a transmission / reception signal blocking mode There is an effect that can be used continuously.

Another effect of the present invention is that it is possible to use the functions in the mobile phone basically related to time, so that the information in the mobile phone can be conveniently utilized even when traveling.
