1. Technical Field
Embodiments of the present disclosure relate to incoming call management, and particularly to a method for forwarding incoming calls received by a communication device during the charging of a battery of the communication device.
2. Description of Related Art
When an incoming call is received by a communication device during the charging of a battery of the communication device, a user may directly answer the incoming call without disconnecting the communication device from the battery charger. However, a great amount of Electromagnetic (EM) radiation may be emitted out during the battery charging of the communication device, which may be very harmful to the user. Therefore, there is room for improvement in the art.
The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one”.
The power supply unit 110 may be a battery, such as a lithium battery. The power supply unit 110 is charged when an external power source, such as a power source of 12V, is connected to the power input interface 111. The power input interface 111 may be a universal serial bus (USB) interface, or other similar interface that capable of power signal transmission.
The detection unit 150 detects whether the power supply unit 110 is in a charging state when an incoming call is received by the communication device 10. The charging state indicates that the power supply unit 10 is being charged at the time when the incoming call is received. In one embodiment, as shown in
In the embodiment, the voltage detection circuit 151 comprises at least one resistance to detect the voltage inputted from the power input interface 111. The comparison circuit 153 includes a comparator which includes two input ports and an output port. The voltage detection circuit 151 is connected to a positive input port of the comparator, the reference voltage generation circuit 155 is connected to a negative input port of the comparator, and the output port is configured to output the control signal to the call forwarding unit 130.
In another embodiment, as shown in
The call forwarding unit 130 forwards the incoming call to a predetermined communication device when the control signal is generated. In one embodiment, the call forwarding unit 130 may execute a call forwarding program of the communication device 10 to forward the incoming call. In particular, the call forwarding unit 130 includes a processing module 131, a storage module 133, and a setting module 135 (see
Referring to
In step S100, when an incoming call is received by the communication device 10, the detection unit 150 detects whether the power supply unit 110 is in a charging state.
In step S200, when the power supply unit 110 is in the charging state and the incoming call is received, the detection unit 150 generates a control signal and outputs the control signal to the call forwarding unit 130,.
In step S300, the call forwarding unit 130 forwards the incoming call to a predetermined communication device when the control signal is received from the detection unit 150.
Although certain embodiments of the present disclosure have been specifically described, the present disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the present disclosure without departing from the scope and spirit of the present disclosure.
