Problems solved by technology
The inventors found that this wireless charging solution has at least the following problems: an additional receiving coil is provided on the terminal device to receive electromagnetic wave energy from outside the terminal device, and the addition of an additional receiving coil leads to an increase in the size of the mobile phone and an increase in cost
However, the inventor found that in this design scheme, since the terminal equipment is in the charging mode, it will convert all the received electromagnetic wave energy into electrical energy, even if the electromagnetic wave energy is an electromagnetic wave signal from the base station to request the establishment of a call connection, which will cause the terminal equipment The call connection cannot be established normally, and the call may be missed

Embodiment Construction
[0029] With the development of electronic equipment technology, the charging technology of mobile phones has developed two technologies: wired charging and wireless charging. The current wireless charging schemes are all realized by coil coupling of tens of megahertz. Since the power transmission of the near-field coupling has a distance limitation requirement, the mobile phone or other charging equipment must be close to the transmitting coil equipment (that is, the power supply equipment). This limits the user's convenience to a certain extent. Many of the above factors limit the popularization of wireless charging technology in mobile terminals. Consumers prefer to charge mobile phones, tablets and other electronic devices as long as there is a signal, especially in various scenarios that require emergency charging such as going out. Although the prior art also provides a wireless charging design scheme, in which the terminal device can receive electromagnetic wave energy...

The invention provides a wireless charging method and terminal equipment. According to the method, the terminal equipment can be charged anytime and anywhere by using electromagnetic wave energy and the terminal equipment is ensured to answer the call in the charging process. The method comprises the steps that the terminal equipment part transmits a wireless charging request to at least one set of network equipment and then receives an electromagnetic wave signal transmitted by at least one set of network equipment. The terminal equipment converts the electromagnetic wave signal into electricenergy and then utilizes the electric energy to charge the power supply of the terminal equipment in the wireless charging mode. When the terminal equipment receives the voice call request signal from at least one set of network equipment in the wireless charging mode, conversion of the electromagnetic wave signal into the electric energy is stopped and the voice call is established according tothe voice call request signal.
Description
technical field [0001] The present application relates to the technical field of electronic equipment, and in particular to a wireless charging method and a terminal equipment. Background technique [0002] With the development of electronic equipment technology, wireless charging technology is being used more and more widely as a simple and flexible charging method. Wireless charging technology refers to the technology of charging terminal equipment wirelessly. The energy is transmitted between the charger and the terminal equipment with a magnetic field, and there is no wire connection between the two. At present, a wireless charging design scheme is to set a "coil" inside the terminal device to couple magnetic energy into electrical energy. When charging the terminal device through this wireless charging technology, the user generally needs to carry a special wireless charging panel, and the terminal device must also There are similar "coil" designs such as figure 1 sh...
