Hereinafter, a schematic block configuration of a hybrid terminal according to an embodiment of the present invention will be described. The composite terminal 100 according to the embodiment of the present invention includes a personal information terminal 110 and a wireless terminal 120. The personal information terminal 110 performs various functions for performing a game or other program. The wireless terminal unit 120 performs a function for wireless communication. In the configuration according to the embodiment of the present invention, a user interface unit such as a display unit or a key input unit, an RF unit for radio signal processing, and the like are not shown.

The first controller 111 of the personal information terminal 110 performs a control operation and a calculation operation for performing the above-described game or other program. The first port controller 112 is powered on / off by the control of the first controller 111 and the first port (not shown) can exchange data with the wireless terminal 120 through the first port 113. 113). The first port 113 may be configured as a serial port as a physical device for exchanging data with a wireless terminal.

The second control unit 122 of the wireless terminal unit 120 performs the above-described control and calculation operations for performing wireless communication. The second port controller 122 is powered on / off by the control of the second controller 121 and the second port 123 to exchange data with the personal information terminal 110 through the second port. To control. The second port 123 may be configured as a serial port as a physical device for exchanging data with the wireless terminal.

In the embodiment of the present invention, the first port controller 112 and the second port controller 122 may be formed of IC chips and included in the controllers 111 and 121. In addition, the first port controller 112 and the second port controller 122 form a link in the idle state by using the interrupt pins of the first port 113 and the second port 123.

An operation according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2 as follows.

Before describing the operation according to the embodiment of the present invention, the controller mentioned below is either the first controller 111 of the personal information terminal 110 or the second controller 121 of the wireless terminal 120. Be aware that

If there is a request for information exchange in step 200, the process proceeds to step 210 to check whether the current link is established. If the link is established, the process proceeds to step 220. If the link is not established, the process proceeds to step 211. In step 211, a link between the personal information terminal 110 and the wireless terminal 120 is established and the sleep and sleep timer is driven. The idle and sleep timers are used as parameters for turning off the power of a predetermined part in the present invention.

In step 220, the controller checks whether there is received data. At this time, the inspection can check whether there is data received by examining the reception buffer (not shown). If there is data received, the flow proceeds to step 230; otherwise, the flow proceeds to step 221. In step 221, it is checked whether there is data to be transmitted. Similar to step 220, the test may determine whether there is data to transmit by checking a transmission buffer (not shown). If there is data to be transmitted, the flow proceeds to step 230; otherwise, the flow proceeds to step 222.

If there is no data transmitted or received, it is a step of checking whether the sleep timer has expired. If the sleep timer is finished, the process proceeds to step 227. If the sleep timer is not finished, the process proceeds to step 223.

If the idle timer expires in step 223, the flow proceeds to step 224 to check whether the timer is being transmitted or received. That is, it is checked whether the response data from the counterpart is not received at the time of transmission, or whether the response data has been transmitted but is not yet transmitted. If it is not transmitting or receiving, the control proceeds to step 226 to transmit control data for maintaining the link to the counterpart and proceeds to step 225 to reset the idle timer. That is, if there is no transmission / reception of data (control data for link maintenance) for a predetermined time, control data for link maintenance is transmitted.

In step 227, it is checked whether there is data to be transmitted or data received. Step 227 may be accomplished by examining the buffer as described above. If there is no data to transmit / receive, the process proceeds to step 228 to release the link and turn off the preset power of the corresponding unit. At this time, the off portion includes a port controller for controlling the pin of the port used for data transmission and reception. However, in order to reestablish the link later, the port controller for controlling the interrupt pin is excluded from the power off target. The configuration of the port control unit in the configuration of Figure 1 is a single, but can be composed of a plurality of port control unit as described above. In addition, in the configuration of FIG. 1, the port control unit is positioned and configured independently of the controller, but may be embedded in the controller.

If there is data to be transmitted or received in step 227, the flow proceeds to step 234 to reset the sleep timer and returns to step 220.

Since data to be transmitted and received exists in step 230, the pause and sleep timers are stopped and a corresponding operation is performed according to the data received in step 231. If the transmit and receive buffers are empty in step 232, the flow proceeds to step 233 to drive the idle and sleep timers and returns to step 220.

1 and 3, the operation of another embodiment according to the present invention is described below.

In step 300, the controllers 111 and 121 of the personal information terminal 110 or the wireless terminal 120 check whether there is a request for information exchange. If there is a request for information exchange, the flow proceeds to step 301 to check if a link is established. If the link is not established, the process proceeds to step 302 to establish the link and to drive the sleep and sleep timers.

In step 310, the controller checks whether there is data to be transmitted or data to be received. If there is data to be received or transmitted, the corresponding operation is performed in step 311. If the processing of the transmitted or received data is completed in step 312, the process proceeds to step 313 to reset the timer and returns to step 310.

In step 320 it is checked whether the sleep timer is finished. When the sleep timer is finished, the process proceeds to step 321 to release the link, and by step 322, the preset power of the corresponding part is turned off. At this time, the off portion is as described above.

In step 330, the controller checks whether the idle timer expires. If the idle timer is finished, the control proceeds to step 331 to transmit control data. In step 332, the idle timer is reset again, and the operation returns to step 310.

Briefly, the present invention is as follows.

If there is no data exchange between the personal information terminal 110 and the wireless terminal 120 for more than the idle timer time, the preset power is turned off, and if there is no data exchange for more than the sleep timer time without the idle timer time elapsed, The control data is transmitted to maintain the link between the personal information terminal 110 and the wireless terminal 120.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims below, but also by the equivalents of the claims of the present invention.

As described above, the present invention can reduce power consumption in the hybrid terminal combined with the personal information terminal and the wireless terminal by turning off the power of the preset part according to the idle time and the sleep timer, thereby minimizing the occurrence of mutual interruption. It can improve the processing speed of the system.
