The present invention relates to a mobile terminal and a method of providing a service through the same. In particular, the present invention relates to a mobile terminal and a method of waiting for operation of a mobile terminal that can immediately respond to a user's use while minimizing terminal power consumption.

In recent years, portable terminals or related systems of terminals have become an essential component indispensable among many people's belongings. Such portable terminals are being developed into a comprehensive function terminal capable of performing various additional functions, including media services such as a conventional voice call service, data communication, multimedia service, MP3, and game machine. This is a result of the convergence of the expansion of the user base, the increase in the use population, the ease of use and portability, and the corresponding technological developments.

These mobile terminals, combined with technological advances in computers, semiconductors, and related electronics industries, are able to execute programs and perform related functions that were not realized in expensive, high-performance personal computers (PCs) just a few years ago. . In addition, in order to accommodate various demands as users expand and increase and provide differentiated services from competitors, various service-related programs are being developed to be realized in systems linked to mobile terminals and portable terminals. .

Such services for users include media services and global positioning systems (GPS), including digital multimedia broadcasting (DMB), which has recently completed a test broadcast and entered a full-scale commercial service. Geographic Information Service (Geographic Information System) using location information service (hereinafter referred to as "GIS"), various games, music, video recording, still image shooting and additional services related to the transmission of such data, including basic data transmission and reception, mail , Internet services are included.

These various services can be realized due to the storage and processing of a lot of data, the execution of complex application programs, and the high-speed processing of various programs and data. Such processing of programs and data has been made possible by the development and dissemination of memory devices with increased density and capacity, the development of high-speed central processing units (CPUs), and the dissemination of small, large-capacity batteries.

On the other hand, the mobile terminal basically provides its own functions to the user, and at the same time, some additional data services are smoothly provided, and the mobile terminal has a limitation of keeping the standby state available at all times during the basic life time of the user. This is an essential requirement to be preceded even in the case of providing such a high quality service. Particularly, in the case of a mobile communication terminal for providing a voice and data communication service, the mobile terminal rarely uses commercial power while in use, so that a small power source attached to the mobile communication terminal, that is, a battery capacity and a use time are used. There are limitations that must be taken into account.

Despite these limitations, companies developing mobile terminals and companies providing services using the mobile terminals offer various methods for providing the best service even under limited conditions. The most common among them is the adoption of a power saving mode for the purpose of minimizing power consumption in idle state. That is, the power of the display device and the keypad of the mobile communication terminal can be turned on and off every few seconds to minimize the power consumption or to simplify the communication procedure for the minimum power communication with the communication system in the idle state. have.

In more detail, unlike a PC using a commercial power source, a mobile communication terminal executes a program only when used so that a user can use a service. This is because the mobile communication terminal uses a small battery, unlike the PC that can always supply power as described above. However, such a method for reducing power consumption has a problem that the above-described time delay for providing a high quality service. That is, the mobile communication terminal is kept in a state of minimizing or stopping execution of various application programs to maintain the minimum power state when the user does not use it. In this state, when a user performs a procedure for using a specific service, a program for providing a service that the user wants to use at that time is executed. Therefore, the user must wait a few seconds to several minutes even after inputting a command for using the service. This is an inevitable delay caused by the performance limitations of processing devices mounted in mobile communication terminals and the minimization of power usage.

On the contrary, when the mobile communication terminal is kept in the All Time Standby Mode in order to immediately respond to the user's demand, there is a problem in that the actual time for which the mobile terminal can be actually used is drastically reduced due to battery consumption. .

Accordingly, there is a demand for a portable terminal and a service providing method in the portable terminal capable of immediately responding to a user's use request while minimizing the power consumption of the portable terminal.

Accordingly, a first object of the present invention is to provide a portable terminal and a method of waiting for operation of the portable terminal that can immediately respond to a user's use request while minimizing terminal power consumption.

In addition, the second object of the present invention is a method of using the various types of sensors in order to achieve the first object, to more clearly detect the user's attempts to use, more immediate response and improved detection accuracy, and the timing of operation of the sensor And a method.

In addition, a third object of the present invention is to include both the software and hardware of the portable terminal, and the portable terminal and the standby method for operating the portable terminal capable of immediately responding to the user's request while minimizing the power consumption in various portable terminals. To provide.

On the other hand, the fourth object of the present invention is to provide a specific example of the sensing data generated in the sensor unit, to facilitate the application in actual use.

In addition, a fifth object of the present invention is to accumulate and use a user's use pattern data, and to provide a method of detecting a user's use attempt more clearly and accurately by using the use pattern data to determine a detection time point and authenticity use attempt. It is.

In addition, a sixth object of the present invention is to provide a method of using a pre-drive agent program for creating the use pattern data, controlling the sensor unit using the use pattern data, and controlling the driving of the drive preparation function.

In order to achieve the above objects, a portable terminal according to the present invention provides a communication channel with an external device for receiving service data including at least one of a text, an image, and a voice from an input unit to which a user's command is input and a separate external device. A memory configured to store a communication unit configured to form a memory, a driving program for driving the portable terminal, and an application program for converting the service data into output data for providing the service data to the user, and for outputting the output data. An output unit, a sensor unit for detecting a user's attempt to use the portable terminal to create sensing data, and determining whether the user uses the portable terminal by using the sensing data, and required for driving according to a determination result One or more with time And a controller configured to perform driving preparation for the component and to switch the component to an operation standby state.

In addition, the operation waiting method of the portable terminal according to the present invention comprises the steps of generating a user's use attempt to use the mobile terminal, the step of detecting the use attempt;

Performing a driving preparation to switch to an operation standby state, inputting a user's command for use of the function, and driving the component in the operation standby state in response to the command.

Other features and operations of the present invention other than the above object will become apparent from the description of the embodiments with reference to the accompanying drawings. Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 9.

1 is a block diagram schematically showing a portable terminal of the present invention.

Referring to FIG. 1, a portable terminal according to the present invention includes a control unit 1, a sensor unit 2, an input unit 4, an output unit 6, a memory unit 8, and a communication unit 10.

The sensor unit 2 detects a user's attempt to use the portable terminal, creates sensing data, and provides the generated sensing data to the controller 1. The sensor unit 2 detects a time when the user touches or moves the portable terminal in order to use the portable terminal in an idle state. To this end, the sensor unit 2 may be implemented using various types of sensors, including touch sensing, heat sensing, movement sensing, pressure sensing and acceleration sensing. Then, the sensor unit 2 detects a user's attempt to use at a predetermined cycle by the sensing control signal from the controller 1. Specific operations and functions of the sensor unit 2 according to the type of sensor will be described later with reference to FIG. 2.

The control unit 1 determines whether the user uses the portable terminal by using the sensing data, and according to the determination result, the idle program, the application program, the input unit 4, the communication unit 10, the memory unit 8, and the output unit. The unit 6 is switched to the operation standby state. In addition, the control unit 1 creates the user's portable terminal use data and records it in the memory unit 8. For example, the frequency of use of the user's portable terminal and the frequency of use of frequently used application programs, devices or functions are calculated and recorded in the usage pattern data area of the memory unit 8. In addition, the controller 1 determines a point in time at which the user attempts to detect the user using the recorded usage pattern data, and drives the sensor unit 2 to detect the user's attempt at using the determined time point. In addition, when the user's attempt to use the portable terminal is detected, the controller 1 may prepare a driving time required for driving, that is, a driving program having a relatively long driving preparation time, an application program, an input unit 4, a communication unit 10, and a memory 8. And some of the components such as the output unit 6 are switched to the operation standby state before a user inputs a command. Through this, the control unit 1 drives some of the components before the user inputs the command, and converts the components to a state immediately before the user's use, that is, a standby mode. Accordingly, the control unit 1 may minimize the inconvenience caused by waiting for a relatively long time of the user by advancing the drive dimming time generated after the input of the use command of the user's component to before the user's use time.

The input unit 4 receives a user's command and transmits it to the controller 1. To this end, the input unit 4 includes a voice input device through which voice data from a user is input, such as a microphone, a touch input device such as a keypad, a touch pad or a touch pad, and a photographing device such as a camera. It can be configured as.

The output unit 6 outputs and provides a result according to the operation of the portable terminal to the user. For example, when the mobile terminal is a mobile communication terminal, the output unit 6 provides the user with a video and audio output device through the video and audio output devices, the audio signal and data processed by the controller 1 and various services provided from the mobile communication system. to provide. To this end, the output unit 6 includes an audio output device such as a speaker, and an image output device such as an LCD (Liquid Crystal Display Device) and an ELD (Electro Luminescence Display Device) monitor.

The memory unit 8 stores a driving program for driving the portable terminal and an application program for converting the service data into output data in order to provide service data to the user. The driving program includes an operating system (OS), a sensor unit 2, an input unit 4, an output unit 6, a memory unit 8, and a communication unit 10 for overall operation and operation of the portable terminal. Drive driver for initialization, driving, and operation. The application program (or application program) is a stand-by program for identifying a user's attempt to use by sensing data and for switching the driving readiness function (LTNF) to an operation standby state when the user uses a mobile terminal. ). The usage pattern data area of the memory unit 8 stores usage pattern data including information on a user's portable terminal usage cycle, usage time, and programs with high usage frequency.

The communication unit 10 forms a communication channel with the external device to receive service data for providing text, video, and voice services from a separate external device. In addition, the communication unit 10 provides data received through the formed communication channel to the control unit 1 and transmits data relayed through the control unit 1 to an external device. The communication unit 10 may be different according to the type of portable terminal. That is, if the portable terminal is a mobile communication terminal, the communication unit 10 includes a mobile communication module capable of forming a communication channel with the mobile communication system. In addition, in the case of a data communication terminal such as a PDA (Personal Digital Assistant), it is possible to communicate with data communication networks such as a wireless local area network (WLAN), Bluetooth, Ubiquitous, Zigbee, etc. A data communication module is provided. In addition, when the portable terminal has a radio wave identification function, the communication unit 10 may include an RFID reader (Radio Frequency Identification Reader). In addition, when the portable terminal is a portable video / audio playback device or a portable game machine, that is, when continuous communication with an external device is unnecessary, the communication unit 10 may be connected to an external device by wire, a near-infrared communication port, or a portable storage device. It is possible to be provided in the form of a socket of the device.

2 is a view showing an example of the sensor unit of the present invention shown in Figure 1, Figure 2a is a view showing the application of the touch sensing, piezoelectric, magnetic sensing sensor unit, Figure 2b is to use the sensor of Figure 2a In this case, the installation position distribution of the sensor unit is briefly shown. In addition, Figure 2c is a diagram showing an application example of the movement-sensitive, acceleration-sensitive sensor.

As already mentioned in FIG. 1, the sensor unit 2 is for detecting a user's point of use of a mobile terminal, and includes an acceleration sensing type, a movement sensing type, a touch sensing type, a heat sensing type, a magnetic sensing type, a piezoelectric type, and a pressure sensing type. It can be implemented using various types of sensors such as a type sensor. In addition, the sensor unit 2 may be operated in combination by using two or more different types of sensors.

When a user uses a portable terminal, a conventional portable terminal is in a state such as a pocket or a bag or placed on an object such as a desk. In this case, in order for a user to simply move or use the portable terminal, the user grasps an unspecified portion of the portable terminal as shown in FIG. 2A. If this is the case, the user intends to use the portable terminal, and the user goes through a process of fixing the portable terminal in a convenient direction. For example, a portable terminal is a mobile communication terminal, and closed terminals, commonly referred to as "folders", must first proceed with opening a case, flip, or part. In order to proceed with the opening process, the user changes the method of holding the outer case of the portable terminal as shown in FIG. 2A, unlike the case of moving the portable terminal. Similarly, even when the portable terminal is a portable video / audio reproducing apparatus, even when the user rotates or key-operates the portable terminal in the right direction to drive the portable terminal, the method of holding the portable terminal or hand position is limited. do.

In this case, as shown in FIG. 2B, when the user uses the components of the portable mobile terminal, the part 12 in which the user's hand is expected to be located is a pressure sensor, a touch sensor, a thermal sensor, an infrared sensor, a piezoelectric sensor, A touch sensing sensor such as a magnetic field sensor is installed. Through this, it is possible for the user to distinguish and sense the position or the holding method of the hand in the step of initially moving or rotating the portable terminal and the position or the holding method of the hand for use. In particular, in order to more accurately detect the user's attempt to use it is preferable to use a mixture of two or more different types of sensors.

On the other hand, as shown in Figure 2c it is also possible to use the movement detection sensor 14. In particular, the acceleration sensor among the movement sensing sensors can be easily mounted in the portable terminal due to its small size, and can be driven at low power, thereby not significantly increasing the power consumption of the portable terminal. In addition, since the acceleration sensor has been widely distributed at a low price due to the recent expansion of the use range, it is possible to reduce the burden due to the increase in manufacturing cost when implementing the sensor unit using the acceleration sensor.

When the sensor unit 2 is implemented using an acceleration sensor, it is determined whether the portable terminal is moved when the user takes out the portable terminal from a storage place such as a bag or a pocket, or moves the portable terminal to use a portable terminal placed on a table or the like. The user's attempt to use is detected. In this case, the user's attempt to use may be determined by using the movement time of the portable terminal measured by the sensor unit 2 and the movement time recorded by the control unit 1 together. For example, when the user moves the mobile terminal to confirm the mobile terminal for 1 second and the time for moving the mobile terminal to take 1.5 seconds, the sensor unit 2 determines whether the mobile terminal is moved. The sensing data is generated by sensing, and the generated sensing data is provided to the controller 1. The control unit 1 records the time at which the portable terminal moved by the presence or absence information included in the sensing data. On the other hand, when sensing data indicating that there is no movement of the mobile terminal is provided to the controller 1, the controller 1 calculates the time required for the movement, and determines whether the movement time is close to 1 second or close to 1.5 seconds. Done. In addition, when the acceleration sensor is used, the user's attempt to use the mobile terminal can be determined using various information such as the acceleration direction of the portable terminal, the number of switching of the acceleration direction, the duration of the acceleration, the interval between the occurrence of the acceleration and the deceleration.

The movement sensor may use both a method using a frequency outside the audible frequency range, such as low frequency and ultrasonic waves, and a method of converting energy according to the movement of the portable terminal into electricity. In addition, the pressure sensor may use a Hall sensor that detects an electric field caused by a magnetic field. In the case of a temperature sensor, a sensor made of metal oxides such as manganese, nickel, and cobalt and semiconducting barium titanate is widely used, and can be implemented at a low manufacturing price. In the case of this temperature sensor, it is easy to use a method of detecting temperature through a resistance change with temperature, typically a NTC thermistor (Negative Thermal Coefficient Thermister) whose resistance value decreases as the temperature rises, and a resistance as the temperature rises. There is a PTC thermistor (Positive Thermal Coefficient Thermister) that increases in value. In addition, in the case of a passive infrared sensor or an IR detector, both a single element type and a dual element type may be used by detecting infrared rays generated from a user's body.

3 is a flowchart briefly illustrating a sensing algorithm for detecting a user's use attempt.

The sensor unit 2 of the portable terminal performs an important function of detecting a user's attempt to use the terminal. As described above with reference to FIG. 2, the sensor unit 2 may use various types of sensors. However, when the sensor unit 2 is always operated in a sensing standby state (All_Time Standby Mode), a large amount of power is consumed through the sensor unit 2. As mentioned above, it is not preferable that the sensor unit 2 of the portable terminal is always kept in a sensing standby state because the portable terminal is restricted from using a small battery as a power source. 3 illustrates a method for determining a sensing time of the sensor unit 2 through a simple flowchart.

Referring to FIG. 3, the portable terminal after turning on the power waits for a user's command or a connection from an external device in an idle state (S10). At this time, the controller 1 initializes the sensing condition value cond of the memory unit 8. Here, the sensing condition value cond is a variable whose value changes according to a predetermined condition such as time, and is a value for determining a sensing period of the mobile terminal.

When the sensing condition value is initialized in step S10, the sensor unit 2 of the portable terminal detects a user's use attempt (S20). Here, according to the detection result, a program stored in the memory unit 8 is driven, or the hardware is switched to an operation standby state.

On the other hand, if the user's usage attempt is not detected in step S20, the controller 1 of the portable terminal compares the sensing condition value cond and the reference condition value Re_cond, and determines whether to redetect the user's usage attempt. It is made (S30). Here, the reference condition value Re_cond may be stored in advance to be compared with the sensing condition value cond for the determination of the detection time, or the time information may be recorded as a value changed by the user's use period information. In this case, when the sensing condition value cond satisfies the reference condition value Re_cond, the sensor unit 2 detects the user's use attempt again.

Meanwhile, if the sensing condition value cond does not satisfy the reference condition value Re_cond in step S30, the controller 1 changes the sensing condition value cond. In this case, when time information is used as the sensing condition value cond, the controller 1 increases or decreases the time recorded in the sensing condition value cond. For example, when the time unit to be increased or decreased is 1 second, the controller 1 increases or decreases the time information recorded in the sensing condition cond by 1 second (S40).

When the sensing condition value cond is changed, it is again determined whether the changed sensing condition value cond satisfies the reference condition value Re_cond. That is, when time information is recorded in the sensing condition value cond and the sensing condition value increases or decreases in step S40, the time information and the reference condition value Re_cond included in the sensing condition value cond increased or decreased in step S30. Compared with the time information stored in the (S30). For example, when the user attempts to use the device every 100 seconds, the reference condition Re_cond becomes 100 seconds. In addition, since the sensing condition cond at the time of detecting the maximum use is immediately after initialization, the sensing condition value cond becomes 0. After the first attempt to detect the use, the values of the sensing condition cond are increased in units of 1 second, such as 0, 1, 2, while repeating steps S30 to S40. Thereafter, when the sensing condition value cond satisfies the reference condition value Re_cond, that is, the sensing condition value cond is 100 seconds, the sensor unit 2 detects the user's attempt to use again. In this way, by adjusting the reference condition value Re_cond, the detection period can be changed even when using the device, thereby reducing the amount of power consumed while smoothly detecting the user's use attempt.

4 is a flowchart briefly illustrating an operation process of a sensor unit in consideration of a user's use period of a mobile terminal and a frequency of use of an application program.

As shown in FIG. 3, the user's use attempt detection cycle may be simply implemented in a manner that elapses over a predetermined time. However, when the information on the user's habit is added to the method mentioned in FIG. 3, the detection period can be more precisely determined. This example is shown in FIG. 4. In FIG. 4, a user's use attempt is sensed in consideration of a period in which a user uses a terminal and a frequency of use of an application program mainly used. In addition, according to the frequency of use of the application program, it is possible to switch the application program to the operation standby state when the user uses the portable terminal so that the user does not feel inconvenience due to time delay.

Referring to FIG. 4, the powered-on portable terminal maintains an idle state for inputting a user's command or waiting for a communication request from the outside (S100). The idle portable terminal detects a user's attempt to use the portable terminal at a predetermined time (S120). As described above, detecting the user's attempt at a predetermined time is a method for reducing power consumption generated when the sensor unit 2 is operated in a sensing standby state at all times.

When the user's usage attempt is detected in step S120, the controller 1 of the portable terminal switches a function having a high possible use frequency n_app among the existing components to an operation standby state. Here, when data on the frequency of use is not secured, or when there is a component having the same frequency of use, it is possible to further apply other determination factors for determining the priority of the components. For example, assuming that there are desktop information output programs and camera shooting functions as components having the same frequency of use, the components that are mainly used in the current time zone are switched to the standby mode, or recently used components. It is also possible to use a method to give priority to (S150).

When the portable terminal switches the frequently used components to the standby operation state, the controller 1 of the portable terminal calculates the interval of use of the portable terminal t_se of the user using the time and current time the user recently used the terminal. do. In addition, the controller 1 calculates an average usage interval t_seav using the calculated mobile terminal usage interval t_se (S160).

In addition, the mobile terminal checks whether the user uses the component that has been switched to the operation standby state or other components, and calculates the frequency of use (n_app) of the component used by the user (S170). In this case, the calculated frequency of use of the component (n_app) is used as a basis of determination in step S150 to select the component to be driven before, if the user later uses the portable terminal. While calculating the average use time t_seav and the use frequency n_app by the controller 1, the user ends the use of the mobile terminal after using the component or other function to be used (S180).

The user terminates the use of the portable terminal, and the portable terminal checks whether a predetermined time has elapsed in order to detect the user's use attempt again. At this time, if there is no separate condition, the portable terminal determines whether the average usage attempt time t_seav has elapsed since the user recently used the portable terminal or whether the average usage attempt time t_seav has elapsed since the last use attempt detection. It becomes (S130). If the average usage attempt time t_seav has not elapsed, the portable terminal maintains a standby state until the average usage attempt time t_seav has elapsed (S140).

On the other hand, if the average usage attempt time t_seav has elapsed, it is again determined whether the user's usage attempt is detected (S120). At this time, if the usage attempt is not detected, the steps S130, S140, and S120 may be selectively repeated to periodically detect the user's usage attempt.

5 is a view briefly showing the concentration of the number of times the user attempts to detect use time.

Referring to FIG. 5, when detecting a user's use attempt by the method as shown in FIG. 4, if one use attempt detection is performed for each average use try time t_seav, a problem may occur that the detection efficiency of the use decreases. have. In order to prevent this, it is preferable to increase the detection accuracy of the use attempt by increasing the number of detection attempts at a constant rate in a predetermined period before and after the average use attempt time t_seav. That is, in the graph of FIG. 5, the interval between the floor and the floor becomes the average use time t_seav. For a predetermined time before and after this floor, the sensor unit 2 is temporarily switched to a standby state for waiting at all times to wait for a user's use attempt. In addition, before and after the temporary always-time detection standby state, the driving of the sensor unit 2 for detecting the user's usage attempt is performed at a short time interval, so that the user's use may occur before and after the average E attempt time t_seav. The degree is more accurately detected.

In such a portable terminal, a driving preparation function that requires a relatively long time for a user to use is a software such as a driving program, an application program, an input unit 4, a communication unit 10, a memory 8, or an output. Applicable to all of the hardware (part 6). Here, the driving program includes an operating system (OS) for operating a basic mobile terminal, and a driving driver (Drvier) for driving each device and a service function.

In addition, the period of detecting the user's usage attempt is preferably determined within a period of approximately 1 to 1 / 1,000,000 of the portable terminal usage period, that is, the average usage attempt period t_seav. In particular, it is more preferable to determine the usage detection period within 1/100 to 1/1000 periods of the average usage attempt period t_seav, since the detection accuracy of the usage time can be improved. As mentioned above, if the usage detection period is close to 1 / 1,000,000 of the average usage attempt period (t_seav) or shorter than this, the detection accuracy of the usage attempt is increased, but it may cause more power consumption than necessary. There is a problem. In this use, the detection period may vary depending on the mobile terminal. In case of frequent use such as a mobile communication terminal, the average use attempt period (t_seav) becomes very short, and in the case of a portable game machine with relatively low use frequency, the average use attempt period (t_seav) becomes longer than that of the mobile communication terminal. Because it can. In addition, even if the same type of terminal is used according to the personal preference of the user, since the average use attempt period t_seav may vary, it is not recommended to limit the detection period to use at a constant value.

In addition, the mobile terminal mentioned in the present invention is a mobile communication terminal, PDA, smart phone, portable audio device, portable still / video playback device, portable VOD device, portable game machine, RF ID Terminals such as a RFID reader. In addition, it can be easily applied if the component requires a relatively long time to prepare the drive.

6 is a flowchart illustrating a driving method for driving the portable terminal of the present invention.

Referring to FIG. 6, the terminal in a state that is not used by the user maintains an idle state (S310). The idle mobile terminal remains idle until a command from a user is input or an attempt is made. In addition, the terminals in the idle state may be stored in a place such as a bag, a handbag, a pocket of clothes, a table, a desk, although there are some differences depending on the intended use.

In this way, in order to use the function of the portable terminal to maintain the idle state or to use the service provided through the portable terminal, the user performs an attempt (or a procedure) for using the portable terminal (S320). For example, picking up a mobile terminal on a desk, taking out a mobile terminal in a pocket, correcting the direction of the mobile terminal, opening a case of the mobile terminal, and unfolding the mobile terminal. It can be considered as an example of the usage attempt for using the terminal. As briefly mentioned above, in order for the user to use the mobile terminal smoothly, if the user acts as in the above example, the part where the user's body is in contact with the mobile terminal or the behavioral procedure may have a certain pattern. do. That is, when the portable terminal is a folder type mobile communication terminal, the user should act to flip the upper folder upward in order to use the portable terminal. To do this, the lower folder is held by one hand and the upper folder is opened by the other hand, or the four fingers and palms of one hand hold the mobile terminal firmly and the folder is opened by inserting a thumb between the folders. Similar patterns can also be found in the previous steps, i.e., in the process of moving the user's portable terminal in a table, desk or clothing pocket to an advantageous position. For example, when a user puts a mobile terminal in the back pocket of the pants, in order to use the mobile terminal in the back pocket of the pants, the user must take out the terminal from the back pocket of the pants. At this time, the portable terminal contained in the back pocket of the pants is stored in an unspecified form, so the user who takes it out must change the position of the hand for convenient use. Such hand changes, changes in pressure, sensing of body temperature, and the like may be considered attempts of use.

When the user attempts to use the portable terminal by the above-described example or a similar method to the idle terminal, the portable terminal detects such a user's attempt (S330).

The sensor unit 2 of the portable terminal that detects the use attempt generates sensing data (S340). The generated sensing data may be generated differently according to the type of sensor constituting the sensor unit 2. For example, in the case of the sensor unit 2 in which a pressure sensor and a heat sensing sensor are mixed, sensing data such as pressure distribution, heat distribution or pressure change, and heat change at the time of a user's use attempt are generated. In addition, when the acceleration sensor is used, contents such as whether the portable terminal is moved, the magnitude of the acceleration, and the duration may be included in the sensing data. The sensing data thus produced is provided from the sensor unit 2 to the control unit 1.

The control unit 1 of the portable terminal provided with the sensing data determines whether the user's use attempt is an authentic use attempt or a false use attempt for using the portable terminal (S350). That is, the user actually attempts to use the mobile terminal by data that is set in advance, such as whether the user changes the holding position of the mobile terminal, or when the time for moving the mobile terminal is longer than the set time, or is changed by the user usage pattern data. Will figure out if you do.

As a result of the determination, it is determined that the user's use attempt is an authentic use attempt, and the portable terminal switches the operation standby state target function among the components to the operation standby state (S360). As described above, the operation standby state target function is determined by data such as the frequency of use (n_app) of the user.

When one, some, or all of the components are switched to the operation standby state, a user's command is input (S370). In this case, when the user uses the component switched to the operation standby state, the user may use the apparatus without a separate waiting time or wait for a driving time shorter than before. In this case, the user's command input may occur faster than the end time of switching to the operation standby state. However, since the component is a process of switching to the operation standby state, the user may use the component in a shorter time than before. Will be.

Meanwhile, when the user's use attempt is a false use attempt in step S350, the terminal periodically detects the user's use attempt until the user's authentic use attempt is input (S350, S330).

7 is a diagram showing a conventional driving preparation time required.

Referring to FIG. 7, the conventional portable terminal maintains an idle state, that is, a preliminary preparation time t1, from an idle state S310 to a command input (or command selection) time point S330. During this preliminary preparation time t1, the user performs the use attempt S320 for using the portable terminal, but the conventional portable terminal did not detect this. Therefore, in the conventional portable terminal, the user's use time is treated the same as the command input time (S330). Therefore, after the user's command is input, the function of the portable terminal is driven. At this time, a delay of the driving preparation time t2 is inevitably generated until the driving completion time (S340), that is, the user-selected function becomes available. The driving preparation time t2 is the processing capacity of the control unit 1 of the portable terminal, the throughput of data and programs for executing the driving required function LTNF, the input unit 4, the output unit 6, and the memory unit 8 And there may be some differences depending on the response speed and processing speed of the device group, such as the communication unit 10, but the components that provide a variety of services or functions will necessarily be longer. After the user waits for the driving preparation time t2, the user can use the selected function only at the completion point of function driving (S340). Thereafter, the portable terminal maintains a driving and activation time t3 capable of performing a function selected by the user. The end point S350 of the function selected by the user is a time point when the portable terminal is switched to the idle state.

As described above, in the conventional portable terminal, the driving preparation time t2 and the driving preparation time t_dr are the same.

On the other hand, Figure 8 is a view showing the drive preparation time required of the present invention.

Referring to FIG. 8, the preliminary preparation time is reduced by the use time t4 of FIG. 7. In other words, unlike the prior art, the preliminary preparation time t1 is advanced by the use time t4, and as a result, the preliminary preparation time t1 'having a significantly shorter time than the conventional preliminary preparation time t1. Changed to In addition, in the related art, a driving preparation time for completing driving of a selected function after the actual user selects a function and inputs a corresponding command was a period between a command input (S330) and a function driving completion (S340) time point. However, in the present invention, the driving preparation time t2 'is changed from the time point of use S420 to the time between function driving time S430 unlike the conventional art. In particular, since the function driving time S430 is before the command input time S430 or at least immediately after the command input time S430, the user's waiting time is very short or very short. More specifically, in the related art, the driving preparation time t2 may be used as the user's waiting time as in FIG. 7, but in the present invention, there is no use waiting time or a very short time.

In addition, the driving active time t3 'to use the function actually selected by the user is a time from the command input point S440 to the end point S450 as shown in FIG. 8, and rather, the function driving completion point S430. The command input waiting time t5 is formed between the command input time point S440 and the portable terminal waits for a user's command input. As described above, the present invention utilizes the wasted use time t4, which is wasted in the related art, and reduces the delay time for driving which the user feels by allowing the drive preparation time t2 to be located before the command input time S440. It becomes possible.

9 is a flowchart illustrating a method of driving a preceding driving agent program for executing an operation waiting method of a portable terminal of the present invention.

Referring to FIG. 9, steps S610, S620, S630, S640, S650, and S660 represented on the left side of FIG. 9 represent operations of the mobile terminal, and S611, S621, S631, S641, and S651 on the right side are pre-drive agents. The program will be run. In addition, the exchange of information and data between them is shown by a dotted line.

In operation S600, an attempt is made by the user to use the portable terminal maintaining the idle state (S610). Meanwhile, the portable state terminal of step S600 is not driven except for an operation program for the minimum power of the portable terminal. At this time, only the pre-drive agent program is executed (S611). That is, if the standby state is always maintained, driving of the component that increases power consumption stops and executes only the pre-drive agent program. The pre-drive agent program executed in the portable terminal in the idle state determines the point of time when the user attempts to use the control unit 2 to control. That is, as described above, by identifying the user's periodic use time, when the mobile terminal reaches the corresponding time, the pre-drive agent program controls the sensor unit 2 to detect the user's use attempt ( S621). As such, the sensor unit 2 that receives the sensing command (SO) from the preceding agent program detects the user's use attempt as in step S620. At this time, if the user's usage is not detected, the pre-drive agent program stops the operation of the sensor 2 or switches to the idle state to reduce the power station. In addition, the pre-drive agent program determines the point of re-detection by determining the point of time when the user is expected to use the user through the pattern data.

When the user's use attempt is detected in step S620, the sensor unit 2 generates the sensing data and provides it to the controller 1. When the sensing data SD is provided in step S620, the preceding driving agent program determines whether the user's use attempt is authentic or false use attempt in step S631. In this case, when the user's use attempt is determined to be a false use attempt, the pre-drive agent program detects the user's use attempt until the user's authentic use attempt is detected as in steps S611 and S621.

On the other hand, if it is determined that the user's use attempt is the authentic use attempt in step S631, in step S641, the preceding driving agent program is ready to drive to the operation standby state through the data such as the component use frequency included in the user use pattern data Select the required function and put the selected component into the standby mode. The component selected in step S641 maintains the operation standby state in step S640. While the selected component maintains the operation standby state, the user's command is input in step S650 and the component corresponding to the command is driven to be used by the user.

On the other hand, a user inputs a usage command, and in step S651, the pre-drive agent program creates the usage pattern data of the user.

As described above, the portable terminal of the present invention and the standby operation method of the portable terminal can immediately respond to the user's demand while minimizing the power consumption of the terminal.

In addition, the present invention provides a method for waiting for a mobile terminal and a mobile terminal using various types of sensors, and providing a timing and method of operating a sensor to more clearly detect a user's use attempt, and improve immediate response and detection accuracy. It becomes possible.

In addition, the portable terminal of the present invention and the method for waiting for operation of the portable terminal can be applied not only to the software and hardware of the portable terminal but also to various portable terminals.

On the other hand, the portable terminal of the present invention and the method of waiting for operation of the portable terminal provides a specific example of the sensing data generated by the sensor unit, it is easy to apply even in actual use.

In addition, the mobile terminal and the method of waiting for operation of the mobile terminal of the present invention accumulate and use the user's usage pattern data, and use the use pattern data to determine the detection time and the authenticity of the user's usage attempt to more clearly determine the user's usage attempt. It is possible to detect accurately.

In addition, the operation waiting method of the mobile terminal and the portable terminal of the present invention provides a method for waiting operation by a pre-drive agent program to create the use pattern data, control the sensor unit using the use pattern data, It becomes easy to drive control.
