In one embodiment, the portable terminal 100 and the external device 200 may have a predetermined state associated with the wakeup mode switching process, and in a specific embodiment, the docking agent unit 192 of the portable terminal 100 And the docking management unit 292 of the external device 200 can manage the predetermined state. Referring to FIG. 6, when the mobile terminal 100 and the external device are in the sleep mode, the mobile terminal 100 and the external device may be in the sleep mode (S100, S105). When the portable terminal 100 and the external device 200 are in the sleep mode, the portable terminal 100 and the various devices 200 included in the external device 200 (for example, That is, a sub-device) may be in a sleep state in which power supply is cut off or only a sufficient amount of power is available to perform a minimum function (for example, a wake-up function of the corresponding sub-device) The docking interfaces 180 and 280 of the external device 200 can block signal transmission except for predefined terminals. For example, as shown in FIG. 5, if the docking interface 180, 280 includes a USB interface, the USB data transfer channel may be deactivated (e.g., USB D +, D- . As another example, if the docking interfaces 180 and 280 include an HDMI interface, the HDMI data transmission channel may be deactivated. Particularly, when the HDMI data transmission channel is activated, the battery consumption of the portable terminal 100 may increase, so that it is preferable that the HDMI data transmission channel is inactivated in the sleep mode.

In this case, however, signal transmission through all the terminals is not necessarily blocked, and signal transmission through some terminals (for example, USB VBUS or HDMI 5V Power in FIG. 5) may not be blocked.

When the external device 200 receives the key input from the user in the sleep mode, the external device 200 senses the key input (S110) and can be woken up. When the external device 200 wakes up and the sub device of the external device 200 is in the sleep state, the sub device in the sleep state can be woken up. In particular, when the CPU of the external device 200 is in the sleep mode at the time of wakeup, the CPU wakes up (S120). On the other hand, in a specific embodiment, it is possible to wake up only when a specific key input is received. Here, the specific key may be a hold key.

When the external device 200 is woken up, the state of the external device 200 may be shifted to a state of 'performing a wakeup operation' (S130).

Also, if the external device 200 wakes up, the external device 200 may transmit a predetermined electrical signal to the portable terminal 100 to wake up the docked portable terminal (S140). At this time, the predetermined electrical signal may be a reset signal via USB VBUS (temporarily turning off the power supplied through the USB VBUS and then supplying power again), or the HDMI CEC pin or the HDMI utility pin (HDMI pin 14) Lt; / RTI >

As described above, when the portable terminal 100 and the external device 200 enter the sleep mode, the data transmission channel between the portable terminal 100 and the external device may be inactivated, , It is possible to activate the deactivated data transmission channel. In a specific embodiment in which data is exchanged with each other via USB between the portable terminal 100 and the external device 200, the step of activating the USB data transmission channel (for example, connecting USB D + and D-) May be included in the wakeup mode switching method (S150).

On the other hand, the portable terminal 100 receiving a predetermined electrical signal from the external device 200 can always be woken up by a predetermined electrical signal (S125). If the sub-device of the mobile terminal 100 is in the sleep state when the mobile terminal 100 is woken up, the sub-device in the sleep state can be woken up. In particular, when the CPU of the portable terminal 100 is in the sleep mode at the time of wakeup, the CPU wakes up (S125).

As described above, when the portable terminal 100 and the external device 200 enter the sleep mode, the A / V data transmission channel between the portable terminal 100 and the external device may be inactivated, When waking up, you can activate the disabled A / V data transmission channel. In a specific embodiment in which A / V data is exchanged with each other via HDMI between the portable terminal 100 and the external device 200, a step of activating the HDMI data transmission channel may be included in the wake-up mode switching method according to the present invention . Here, the activation of the channel means that the data can be transmitted through the corresponding channel or the data is transmitted. In particular, in order to activate the HDMI data transmission channel, the mobile terminal 100 may issue a command to start transmission of TMDS (Transmission Minimized Differential Signaling) signal to the HDMI module (S 155).

Thereafter, the state of the portable terminal 100 can be changed to 'performing a wakeup operation' (S135), and the external device 200 transmits a start message to the portable terminal 100 to continue the remaining wake- (160). Then, the mobile terminal 100 sends a response (Ack) to the start message to establish the connection (165) and continues the remaining connection establishment process.

Before the portable terminal 100 and the external device 200 are switched to the sleep mode, the portable terminal 100 and the external device are connected to each other via a predetermined connection establishment process, The control path can be reset to use the device instead. When the portable terminal 100 and the external device are switched to the sleep mode and then wake up again, the portable terminal 100 and the external device 200 are switched to the wake-up mode by performing the predetermined connection establishment process again It is necessary to ensure that the state before the sleep is maintained even after that.

FIG. 7 is a flowchart showing the connection establishment process that can be performed after the process shown in FIG. Referring to FIG. 7, the external device 200 can transmit predetermined information so that the portable terminal 100 can acquire sub-device information included therein (S170). The predetermined information may be a list of specific information about each sub-device included in the external device 200, and may be information in a form similar to the table of the identification number 201 shown in FIG. On the other hand, in the specific embodiment, the predetermined information may be the identification information of the external device 200 itself, as shown in FIG. In this case, the mobile terminal may include a table (e.g., a database) for storing information of various external devices compatible with itself (that is, correctly docked and connected) and subdevices included in the external device , The information of the sub device included in the external device 200 may be obtained by searching the database with the identification information of the delivered external device 200. [

Subsequently, the portable terminal 100 acquires a list of subdevices included in the external device 200 using the acquired subdevice information of the external device 200, and acquires a list of subdevices included in the list, (Hereinafter, referred to as " first sub-device ") of the external device 200 to be used instead of the device included in the portable terminal itself List) to the external device 200 (S180).

Then, the external device 200 can transmit a connection establishment termination message (S190).

The portable terminal 100 acquires information on a sub-device (hereinafter referred to as 'second sub-device') of the portable terminal corresponding to the first sub-device, in particular, the status information of the second sub-device (S200) To the external device 200 (S205). Then, the external device 200 reflects the received information of the second sub-device to the first sub-device, so that the status of the first sub-device of the external device 200 is the same as the status of the second sub-device of the portable terminal 100 (S210). For example, the first sub-device is an audio output device included in the external device 200, the second sub-device is an audio output device of the corresponding portable terminal 100, and the audio output device of the portable terminal If the state of the audio output apparatus of the external device 200 to be replaced with the audio output apparatus of the portable terminal 100 is changed to the audio output of the portable terminal 100 after the docking connection is established As with the status of the device, it is set to either off (off) or one-step volume. By doing so, the portable terminal maintains consistency before docking and after docking, and it is possible to eliminate the inconvenience that the user has to reset the external device after docking.

The mobile terminal 100 reconfigures the sub-device control path so that the first sub-device performs the function performed by the second sub-device before docking (step S220). The control of the sub-device allows control (hereinafter referred to as 'event control') for processing the event when an event (also referred to as an event signal or an I / O signal) occurs from the sub-device and a sub- (Hereinafter referred to as " command control "). When key input is performed through the touch panel, an event handler (or a signal handler) corresponding to a key input event is called to process an event, for example, as an event control. In order to turn on / off the backlight, One example of command control is to issue a brightness value adjustment command to lower or adjust the brightness.

In one embodiment, a predetermined second event is generated by the second subdevice of the portable terminal 100 before docking, but after the docking, the first event is performed by the first subdevice of the external device instead of the second event The first event will occur. Therefore, after the docking connection, the portable terminal 100 needs to reconfigure the event control path so as to process the first event instead of processing the second event. In another embodiment, before the docking, the portable terminal 100 issues a predetermined control command to the second device according to the input of the user or the necessity of the operation of the portable terminal 100. However, after the docking, It is necessary to reconfigure the command control path so as to issue the control command. This control path reconfiguration will be described later in detail with reference to FIGS. 10 to 11. FIG.

After the control path reconfiguration, the mobile terminal 100 may suspend the second sub device or deactivate the second sub device by powering off the second sub device (S230).

Then, the mobile terminal 100 transmits a connection establishment termination message response (Ack) to the external device 200 (S195) to notify that the connection establishment process has been performed, and transits the state to the 'connection' state (S250).

The external device 200 may also transition its state to the 'connected' state (S255) and may transmit an HDMI display start command to the HDMI module to display the HDMI A / V data signal input from the portable terminal (S240).

Not all of the steps of the process described above with reference to Figs. 6 to 7 are all essential, and some of the steps may not correspond to the components necessary for implementation of the present invention. For example, the step of transiting the state of the portable terminal 100 or the external device 200 is not necessarily a necessary step because it is for ease of explanation or implementation, and the connection establishment start / end message, connection establishment start / It is also the case to send a message response.

[Description of Fig. 8 and Fig. 9]

FIG. 9 is a block diagram showing a control path before docking connection establishment, and FIG. 10 is a block diagram showing a control path after docking connection establishment. The arrows indicated by dashed lines in FIGS. 9 and 10 indicate the path of event control generated and transmitted from the sub device, and arrows indicated by solid lines indicate commands directed to the sub device from the App, Control path.

Hereinafter, the reconfiguration of the control path according to the establishment of the docking connection in the wakeup process according to the present invention will be described with reference to FIGS. 9 and 10. FIG.

Referring to FIG. 9, the control command before docking connection establishment starts from an application (App) layer and passes through a framework layer, a hardware abstraction layer (HAL), a control root management unit 194, 2, and when an event occurs in the second sub-device, it is transferred to the application layer through the device driver of the kernel, the control root management unit 194, the HAL, and the framework layer. In a conventional portable terminal, a control command / event signal will be transmitted between the kernel device driver and the HAL without going through the control route management unit 194. In the case of the portable terminal 100 performing the connection establishment process according to the present invention, A control route management unit 194 may be further included for reconfiguration.

When a docking connection is established between the portable terminal 100 and an external device, the control command transferred to the control route management unit 194 via the application layer and the framework layer HAL is included in an external device other than the device driver of the second sub-device The event signal generated in the first sub-device is transferred to the control-route management unit 194, and the control path is reconfigured so that it can be processed in the application layer via the HAL framework layer.

The event signal and the control command may be transmitted through the docking agent unit 192 of the portable terminal 100 and the docking management unit 292 of the external device 200. In this embodiment, 10 as shown in FIG. That is, when the docking connection is established, the control route management unit 194 transmits a control command to be transmitted to the second sub-device to the device driver of the first sub-device as a docking agent . Meanwhile, the event signal generated in the first sub-device is transmitted to the docking agent via the docking management unit, and the docking agent can inform the control root management unit 194 that an event has occurred from the first sub-device.

The docking agent unit 192 registers a predetermined module (or a function) in order to receive the control command from the control route management unit 194 and the control route management unit 194 calls the predetermined module Command. In this embodiment, the module of the kernel driver for controlling the second sub device at the time of initialization of the portable terminal and the module of the docking agent unit 192 corresponding thereto are registered in the control route management unit 194, and the control route management unit 194 ) Can reconfigure the control path by determining which module to call depending on whether the connection is docked.

In another specific embodiment, the docking agent unit 192 may call the predetermined module (or function) implemented in the control route management unit 194 to inform the control route management unit 194 of the occurrence of the event. In this embodiment, the control-route managing unit 194 determines which event, such as an event coming from the kernel drive or an event coming from the docking agent, is to be handled according to whether the docking connection is established or not, and can transmit the event to the handler for processing the event . Meanwhile, the handler may be implemented in the control route management unit 194 or may be implemented in a layer separate from the layer where the control route management unit is located.

9 and 10 show that the control route management unit 194 is installed in the kernel layer and the docking agent unit 192 is installed in the application layer. However, according to the embodiment, the control route management unit 194 is installed in the HAL Or the docking agent unit 192 may be mounted in the framework layer or the HAL. The docking management unit 292 of the external terminal may also be mounted in the framework layer or the HAL, unlike in FIGS.
