Mobile terminal, communications module and control method of mobile terminal

A communications module comprising:

• a module substrate;
• a communication controller on the module substrate, the communication controller electrically connected to a communications coil, the communication controller being configured to detect a wireless tag;
• a wireless charging controller on the module substrate, the wireless charging controller electrically connected to a power receiving coil to receive power wirelessly;
• and
• a power management controller on the module substrate, the power management controller electrically connected to the communication controller to supply power to the communication controller,
• wherein the communication controller and the wireless charging controller are configured to provide control signals to each other through conductive lines formed between the communication controller and the wireless charging controller, and
• wherein the wireless charging controller is further configured to wake up the power management controller in response to receiving a wake-up power signal from a wireless power transfer apparatus.

A control method of a mobile terminal performed by a wireless charging controller, the method comprising:

• receiving wake-up power signal from a wireless power transfer apparatus;
• waking up a power management controller, which is configured to supply power to a communication controller, in response to the receiving of the wake-up power signal;
• and
• requesting that the communication controller, which is configured to detect a wireless tag in an environment of the mobile terminal and is included in the mobile terminal, determine whether the wireless tag is in the environment of the mobile terminal.

A mobile terminal, comprising:

• a communication controller configured to recognize a wireless tag based on signals from a communications coil;
• a wireless charging controller configured to receive power wirelessly from a wireless power transfer apparatus via a power receiving coil, and output a wired wake-up power signal in response to receiving a wireless wake-up power signal from the wireless power transfer apparatus;
• and
• an auxiliary controller configured to control the communication controller to determine whether the wireless tag is located in an environment of the mobile terminal in response to receiving the wired wake-up power signal from the wireless charging controller, the auxiliary controller further configured to supply power to the communication controller,
• wherein the wireless charging controller is configured to wake up the auxiliary controller in response to receiving the wireless wake-up power signal from the wireless power transfer apparatus.
