Abstract

The invention discloses a method and an apparatus for achieving compatibility of wireless charging and near field communication (NFC), wherein the method comprises the steps of setting an antenna which is specially used for receiving a wireless charging signal and an NFC signal on a communication terminal; by a decision circuit module, judging whether the signal which is received currently by the antenna is a wireless charging signal or an NFC signal by the communication terminal; if the currently received signal is a wireless charging signal, transmitting the charging signal received by the antenna to a wireless receiving circuit module of the communication terminal by the decision circuit module, to receive wireless electric energy; if the currently received signal is an NFC signal, implementing communication of an NFC module of the communication terminal via the antenna by the decision circuit module. According to the invention, coexistence and compatibility of the wireless charging and the NFC are effectively achieved; meanwhile, the problem that a coil is shared by the wireless charging and the NFC is solved.

Description

technical field [0001] The invention relates to the fields of wireless charging and NFC (Near Field Communication), in particular to a method and device compatible with wireless charging and NFC. Background technique [0002] At present, mobile terminals are used more and more widely, and the functions of the terminals are very powerful, full of rich entertainment, such as listening to music, watching TV, surfing the Internet and so on. In the process of using the mobile terminal, due to the limitation of the battery capacity, people find that the power of the battery is used up soon, and the battery often needs to be charged. The emergence of wireless charging technology represented by electromagnetic induction has brought convenience to consumers. The wireless charging device can conveniently charge the mobile phone, freeing consumers from the shackles of wires. [0003] Near field communication NFC, also known as short-range wireless communication, is a short-range wire...
