Information processing terminal with wake on LAN and power control method thereof
View Patent ↗An information processing terminal includes a WOL monitoring unit for monitoring whether or not a particular packet for indicating resumption of operation from a suspended state is received, a resume processing unit for resuming the operation from the suspended state, a factor monitoring unit for recording a factor of the resumption to a memory, a cancel monitoring unit for monitoring whether or not a cancel signal to a communication request received after the resumption is received, and a suspend processing unit for switching the operation to the suspended state when the factor of the resumption is reception of the particular packet as well as the cancel signal is received after the resumption. With this arrangement, power consumption of the information processing terminal can be suppressed.
1. An information processing terminal comprising a CPU and a communication unit for carrying out communication processing to LAN, wherein the CPU comprises:
a WOL (Wake On LAN) monitoring unit for monitoring whether or not a particular packet for indicating resumption of operation from a suspended state is received;
a resume processing unit for resuming the operation from the suspended state;
a factor recording unit for recording whether or not a factor of the resumption is the reception of the particular packet to a memory;
a cancel monitoring unit for monitoring whether or not a cancel signal to a communication request is received after the particular packet is received; and
a suspend processing unit for switching the operation to the suspended state when the factor of resumption is reception of the particular packet, and the cancel signal is received after the resumption.
2. The information processing terminal of claim 1 wherein:
the communication unit comprises an audio processing unit for carrying out processing for a phone call; and
the cancel monitoring unit monitors a signal showing cancel of the phone call as the cancel signal.
3. The information processing terminal of claim 1 , wherein the communication unit carries out connection processing to wireless LAN.
4. A power control method, wherein an information processing terminal carries out steps of;
monitoring whether or not a particular packet for indicating resumption of operation is received when the information processing terminal is in a suspended state;
recording whether or not a factor of the resumption is the reception of the particular packet when the operation is resumed from the suspended state;
monitoring whether or not a cancel signal to a communication request is received after the particular packet is received; and
switching the operation to the suspended state when the factor of the resumption is reception of the particular packet, and the cancel signal is received after the resumption.
5. The power control method of claim 4 , wherein the information processing terminal monitors a signal showing cancel of a phone call as the cancel signal at the step of monitoring whether or not the cancel signal is received.
6. The power control method of claim 4 , wherein the information processing terminal is connected to a wireless LAN.
7. The power control method of claim 4 , wherein the communication request is a Facsimile Over IP (FoIP) request.
8. An information processing terminal comprising a CPU and a communication unit, wherein the CPU comprises:
means for resuming operation of the information processing terminal from a suspended state when a particular packet is received by the communication unit;
means for receiving a cancel signal to a communication request;
means for switching operation of the information processing terminal to the suspended state if both the particular packet and the cancel signal are received by the communication unit.
