It should also be noted that after the smartphone is charged, the call forwarding needs to be cancelled. The specific process is as follows:

S406: When the charging of the smart phone ends, the smart phone sends a call transfer stop signaling to the network side;

The call forwarding stop signaling is used to cancel the call forwarding that is successfully set. Specifically, when the smart phone is fully charged or the wireless terminal is unplugged from the charging device, the charging of the smart phone ends. At this time, the smart phone sends a call transfer stop signaling to the network side, and the specific format may be “##21#”;

S407: After receiving the confirmation signaling returned by the network side, the smart phone converts its mode from the flight mode to the normal working mode or to the working mode before charging.

It can be understood that the smart phone receiving the confirmation signaling returned by the network side indicates that the call forwarding successfully set by the steps S401 to S405 is successfully canceled, so that the situation of forgetting to cancel the call forwarding setting due to the manual operation can be avoided.
