Abstract: This specification relates to the field of mobile communications technologies, and specifically to a network access method and a terminal. The method is applied to a terminal that is connected to the primary access network device and the secondary access network device through the first SIM card, and is connected to the secondary access network device. The method includes: disconnecting, by the terminal, an RRC connection between the terminal and the secondary access network equipment when the terminal executes a first service through the second SIM card; determining, by the terminal, that the first service ends; and actively disconnecting, by the terminal, an RRC connection between the terminal and the primary access network equipment, and sending an RRC connection re-establishment request, so that the terminal is reconnected to the secondary access network equipment through the first SIM card with assistance of the primary access network equipment.

Abstract: A wireless charging apparatus which includes: an accommodation structure and a first charging control circuit. The accommodation structure includes an accommodation cavity and a first wireless charging coil, where the first wireless charging coil can be arranged around the accommodation cavity. In addition, the first wireless charging coil generate an alternating current magnetic field. The accommodation cavity is configured to accommodate a stylus, and a second wireless charging coil is arranged in the stylus. When the stylus is accommodated in the accommodation cavity, the second wireless charging coil is also accommodated in the first wireless charging coil. In this case, the second wireless charging coil can induce an alternating current magnetic field generated by the first wireless charging coil in a plurality of directions, to be coupled to the first wireless charging coil.

Abstract: This application discloses a wireless keyboard. The wireless keyboard includes a connection portion. The connection portion includes an accommodating cavity with an opening at an end and used for accommodating an electronic stylus. A wireless charging coil is arranged in the accommodating cavity. A charging interface and a wireless charging control module are arranged in the wireless keyboard. The wireless charging control module is connected to the charging interface and the wireless charging coil. The charging interface can receive a direct current signal. The wireless charging control module can convert, if it is detected that a direct current signal is inputted to the charging interface, the direct current signal into an alternating current signal and transmit the alternating current signal to the wireless charging coil. The wireless charging coil generates an alternating electromagnetic field in response to the alternating current signal, to wirelessly charge the electronic stylus.
