1 is a block diagram illustrating a mobile communication terminal for setting a discontinuous reception period based on a user event according to an embodiment of the present invention.

Referring to FIG. 1, the mobile communication terminal 20 includes an input unit 210, a display unit 220, a period setting unit 230, a table storage unit 240, a control unit 250, a power supply unit 260, and a radio frequency. The unit 270 and the handset 280 are included.

In the configuration diagram of FIG. 1, components except for the period setting unit 230 and the table storage unit 240 correspond to general components commonly included in the mobile communication terminal, and the period setting unit 230 and the table storage unit. Reference numeral 240 corresponds to a component specially added for the implementation of the method for setting the discontinuous reception period according to an embodiment of the present invention. The general components of the former will be briefly described.

In the configuration diagram of FIG. 1, the period setting unit 230 and the table storage unit 240 are displayed in separate blocks because the mobile communication terminal and the existing mobile communication in which the method for setting the discontinuous reception period according to the present invention are implemented. It is merely to distinguish the terminal more clearly. That is, the control unit 250 may perform the functions and roles performed by the period setting unit 230 and the table storage unit 240 in combination.

The input unit 210 means for inputting a command signal to the mobile communication terminal 20 for executing a user event such as a user transmitting a message to a counterpart and searching for a counterpart phone number or making a call to talk with the counterpart to be.

The input unit 210 is a user interface for receiving various data from a user, and there is no particular limitation on its implementation. In general, the input unit 210 may use a keypad, a wheel key, a touch pad, a touch screen, and a combination of two or more thereof. Recently, the touch screen method is mostly adopted due to increased space utilization, display screen and enlargement requirements, and design considerations. In this case, the input unit 210 may be integrated with the display unit 220.

The display unit 220 displays a symbol including letters or numbers input by the input unit under the control of the controller 250. The display unit 220 displays a process or a result for executing the user event in the controller 250.

The display unit 220 may display a state of the user terminal, such as a state of use of the battery, a reception strength of radio waves, a date and time. In addition, the display unit 220 may display operation information, result information, or numbers or letters input through the input unit 210 so that the user can check the operation information generated during the operation of the user terminal.

The period setting unit 230 checks the time at which the user event occurs, and sets the discontinuous reception period using the time at which the user event occurs. The period setting unit 230 includes a user pattern checking unit 233 and a period generating unit 235.

The user pattern checking unit 233 checks an event occurrence time at which a user event occurs, and generates a pattern time table by classifying by time zone. Specifically, the user pattern checking unit 233 counts the user event when the control unit 250 executes the user event, and generates an event occurrence time by confirming the time for executing the user event in the control unit 250.

The user pattern checking unit 233 classifies the event occurrence time by time zone, and generates a pattern time table using the event occurrence time classified by time zone. In other words, the user pattern checking unit 233 generates a pattern time table by counting the number of user event occurrences for each time zone and matching the time and the number of user event occurrences.

Here, the user event is a call request event that occurs when a user requests a call to the other party, a message receiving event and a message originating event that occur when a user receives or sends a message, and a call receiving event that occurs when the other party requests a call to the user. It may include at least one.

The period generator 235 sets a discontinuous reception period using the pattern time table. In other words, the period generation unit 235 checks the pattern time table and sets the discontinuous reception period for each time zone according to the determination criteria. The period generator 235 stores the discontinuous reception period in the table storage unit.

In detail, the period generator 235 determines the number of user event occurrences for each time zone using a pattern time table, and generates an average value of events using the number of user event occurrences. For example, the period generator 235 may generate an average value of the event by obtaining an average value of the number of user event occurrences that occur in one day, and set a certain period (one week, one month, one year, etc.) to generate a user event that occurs at a predetermined period. The average value of the number of times can be obtained to generate the average value of the event. The period generator 235 may generate an average value of events by obtaining an average value for each time period of a predetermined period. In addition, the period generation unit 235 can calculate the average value for each day of the week and use it as the event average value. The period generating unit 235 sets the criterion to the event average value, and sets the discontinuous receiving period to be short when the number of occurrences of the user event is larger than the event average value. The period generator 235 sets the discontinuous reception period to be longer when the number of occurrences of the user event is smaller than the average value of the event.

Accordingly, the period generation unit 235 may determine the time used by the user using the user event occurrence time and set the discontinuous reception period. Here, the period generation unit 235 has limited the determination criteria to the event average value, but not limited thereto, and may set the determination criteria according to a predetermined algorithm (eg, a program, a probability model, etc.). For example, the period generator 235 may set a predetermined number of times as a criterion to determine a discontinuous reception period when the number of user events is greater than a predetermined number of times, and set a discontinuous reception period when the number of user events is less. have.

In addition, the period generator 235 may set the discontinuous reception period by using a difference value between the number of occurrences of the user event and the average value of the events. The period generator 235 may set a discontinuous reception period differently for each difference value. In detail, the period generator 235 sets the discontinuous reception period shorter as the difference between the event average value and the number of user event occurrences becomes a positive value, and sets the discontinuous reception period longer as the difference becomes a negative value. When setting the discontinuous reception period according to the difference between the number of occurrences of the user event and the average value of the events, the period generator 235 may set the discontinuous reception period by using a predetermined algorithm.

The table storage unit 240 stores the discontinuous reception period generated by the period generator 235. In addition, the table storage unit 240 may store the pattern time table generated by the user pattern checking unit 233. The table storage unit 240 may be configured separately from the period setting unit 230 as in the embodiment of the present invention, but may be configured in the period setting unit 230.

The controller 250 sets a standby state and controls to monitor the call instruction signal at each discontinuous reception period. The controller 250 may set a standby state when the user does not use the mobile communication terminal 20 for a predetermined time, and may set a standby state by confirming a time not used by the user by checking a pattern time table. The controller 250 maintains the standby state and controls the radio frequency unit 270 to monitor the call instruction signal at each discontinuous reception period set for each time zone.

When the controller 250 transmits a power supply signal to the power supply unit 260 to supply power to the radio frequency unit 270, the power supply unit 260 supplies power to the radio frequency unit 270.

The controller 250 determines a command signal input from the input unit 210 and controls to execute a user event corresponding to the command signal. The controller 250 controls the display unit 220 to display a command signal input from the input unit 210.

The power supply unit 260 supplies power to the input unit 210, the display unit 220, the period setting unit 230, the table storage unit 240, the control unit 250, and the handset unit 280. The power supply unit 260 supplies power to the radio frequency unit 270 at every discontinuous reception period under the control of the controller 250. The power supply unit 260 is connected to a battery connected to the main body of the mobile communication terminal 20.

The radio frequency unit 270 monitors the call indication signal and receives the call indication signal when the call indication signal is found. In other words, the radio frequency unit 270 monitors the call instruction signal of the mobile communication terminal 20 at the base station under the control of the controller 250. When a call instruction signal corresponding to the mobile communication terminal 20 is found, the radio frequency unit 270 receives the call instruction signal. Accordingly, the radio frequency unit 270 does not periodically monitor the call instruction signal, and under the control of the controller 250, the call instruction signal is monitored at every discontinuous reception period, thereby minimizing power consumption.

The radio frequency unit 270 performs a radio communication function of the mobile communication terminal 20. The radio frequency unit 270 up-converts and amplifies the frequency of the transmitted signal, down-converts the frequency of the received signal, and amplifies low noise. In addition, the radio frequency unit 270 modulates and encodes a transmitted signal and demodulates and decodes the received signal.

The handset 280 outputs the received voice data transmitted from the radio frequency unit 270 or transmits the transmitted voice data to the radio frequency unit 270 through a microphone.

Hereinafter, a method of performing a discontinuous reception by the discontinuous receiving apparatus will be described with reference to FIG. 2.

2 is a flowchart illustrating a process of setting a discontinuous reception period according to an embodiment of the present invention.

Referring to FIG. 2, first, the period setting unit 230 of the discontinuous receiving apparatus 30 checks a time at which a user event occurs (S210). The user pattern checking unit 233 of the period setting unit 230 checks the time at which the user event occurs and sets the event occurrence time. In detail, the period setting unit 230 determines when the user event is executed by the controller 250, and sets an event occurrence time by checking a time for executing the user event. Here, the user event is an event occurring in the mobile communication terminal 20 and may include, for example, at least one of a call request event, a message reception event, a message origination event, and a call reception event.

Next, the period setting unit 230 generates a pattern time table (S220). In detail, the user pattern checking unit 233 of the period setting unit 230 checks an event occurrence time and classifies it by time zone. The user pattern checking unit 233 generates a pattern time table using the event occurrence time classified by time zone. The user pattern checking unit 233 generates a pattern time table by arranging the number of user event occurrences according to time zones and matching the time and the number of user event occurrences.

Next, the period setting unit 230 sets the discontinuous reception period using the pattern time table (S230). The period generation unit 235 of the period setting unit 230 sets a discontinuous reception period for each time zone by using the number of user event occurrences of the pattern time table. In other words, the period generator 235 obtains an average of the number of user event occurrences set for each time zone and sets an average value of the events. In addition, the period generator 235 sets the event average value as a determination criterion, and sets the discontinuous reception period short when the number of user events is greater than the event average value, and sets the discontinuous reception period long when the number of user events is small.

Here, the controller 250 sets the mobile communication terminal to the standby state (S240). The controller 250 may set the standby state when the user does not use the mobile communication terminal 20 for a predetermined time.

Subsequently, the controller 250 controls to monitor the call instruction signal (S250). The controller 250 controls the radio frequency unit 270 to monitor the call instruction signal from the base station at every discontinuous reception period for each time zone.

Thereafter, the radio frequency unit 270 monitors the call instruction signal corresponding to the mobile communication terminal 20 in the base station under the control of the control unit 250 (S260). Specifically, the radio frequency unit 270 is turned on when the power is supplied from the power supply unit of the mobile communication terminal 20, and monitors the call indication signal in the base station.

Finally, the radio frequency unit 270 receives the call instruction signal when the call instruction signal corresponding to the mobile communication terminal 20 is searched by the base station (S270). Accordingly, since the radio frequency unit 270 monitors the call instruction signal to the base station only in the discontinuous reception period, power consumption can be reduced, so that the battery of the mobile communication terminal 20 can be used for a long time.

3 is an exemplary diagram illustrating a pattern time table set by a discontinuous reception period setting mobile communication terminal according to an embodiment of the present invention.

The user pattern confirmation unit 233 of the mobile communication terminal 20 generates a pattern time table as shown in FIG. 3. Here, the X axis represents time and the Y axis represents the number of user event occurrences. Referring to FIG. 3, the number of occurrences of user events between 9 o'clock and 11 o'clock and 19 o'clock to 20 o'clock is 20 cases, 11 o'clock to 14 o'clock, and 50 cases respectively, and 14 o'clock to 18 o'clock. The period setting unit 230 generates an average value of events using the number of user event occurrences. In this case, the average value of the number of user event occurrences per day is used, and the average value of the event is about 24 events. Therefore, the period setting unit 230 sets the discontinuous reception period to 2.56 seconds at 9 o'clock to 11 o'clock and 19 o'clock to 20 o'clock, and sets the discontinuous receiving period to 1.28 second at 11 o'clock to 14 o'clock. The period setting unit 230 sets the discontinuous reception period to 5.12 seconds between 14:00 and 18:00.

In addition, the controller 250 controls the radio frequency unit 270 to monitor the call instruction signal every 2.56 seconds from 9 o'clock to 11 o'clock and 19 o'clock to 20 o'clock, and the call instruction signal every 1.28 seconds from 11 o'clock to 14 o'clock. Control to monitor. The controller 250 controls to monitor the call instruction signal every 5.12 seconds between 14:00 and 18:00. Accordingly, since the radio frequency unit 270 monitors the call instruction signal every short set discontinuity period during the occurrence of many user events, the call instruction signal coming to the mobile communication terminal may be received without being missed. In addition, when the user event occurs less time, the radio frequency unit 270 monitors the call instruction signal for each long set discontinuous reception period, thereby reducing the power consumption.

The discontinuous reception period setting mobile communication terminal according to an embodiment of the present invention may be implemented in the form of program instructions that can be executed by various computer means and recorded in a computer readable medium. Computer-readable media may include, alone or in combination with the program instructions, data files, data structures, and the like.
