| 发明名称 | Method for controlling low-power state in mobile handset | ||
| 摘要 | Provided is a method for controlling a low-power state in a mobile handset. The method includes shifting from an active state to a low-power idle state by blocking power of modules for a mobile communication function and decreasing a frequency of a control clock when an inactive request of the mobile communication function is received; shifting from the low-power idle state to a low-power access state by increasing the frequency of the control clock when an additional service request is received; shifting from the low-power access state to the low-power idle state if an additional service request is not received any more; shifting from the low-power idle state to a suspension state by suspending the control clock when request is not received for predetermined time; and shifting from the suspension state to the low-power idle state when the input interrupt and the timer interrupt occur. | ||

| 主权项 | 1. A method for controlling a low-power state in a mobile handset, comprising: shifting from an active state to a low-power idle state by blocking power of modules for a mobile communication function and decreasing a frequency of a control clock when an inactive request of the mobile communication function is received from a user; shifting from the low-power idle state to a low-power access state by increasing the frequency of the control clock when an additional service request is received from the user in the low-power idle state; shifting from the low-power access state to the low-power idle state if the additional service request is not received any more in the low-power access state; shifting from the low-power idle state to a suspension state by setting an input interrupt and a timer interrupt and suspending the control clock when a request from the user is not received for predetermined time in the low-power idle state; and shifting from the suspension state to the low-power idle state when the input interrupt and the timer interrupt occur in the suspension state. | ||
