Power supplying method for wireless network terminal and wireless network terminal

摘要

A power supplying method for a wireless network terminal and the wireless network terminal are disclosed. The method includes: detecting potential information of two power lines of a USB (Universal Serial Bus) interface of a wireless network terminal; determining, according to the potential information of the two power lines, a type of a power supply device that is connected to the USB interface; and when the type of the power supply device is a power supply device having a communication capability, controlling the wireless network terminal to work in a predetermined communication mode, so as to implement power supply for the wireless network terminal by using the power supply device. With provided technical solutions, a cost of the wireless network terminal can be reduced, and a battery with a relatively large size is not needed, thereby facilitating miniaturization and integration of the wireless network terminal.

主权项

1. A power supplying method, the method comprising:
detecting potential information of two power lines of a universal serial bus interface of a wireless network terminal; determining, according to the potential information of the two power lines, a type of a power supply device that is connected to the universal serial bus interface; and when the type of the power supply device is a power supply device having a communication capability, controlling the wireless network terminal to work in a predetermined communication mode so as to implement power supply for the wireless network terminal by using the power supply device, wherein the predetermined communication mode supports the power supply device having a communication capability in supplying power for the wireless network terminal, except a global system of mobile communication mode, wherein controlling the wireless network terminal to work in the predetermined communication mode comprises:
acquiring a communication mode of the wireless network terminal,determining whether the communication mode in which the wireless network terminal works is a global system of mobile communication mode, andwhen the communication mode in which the wireless network terminal works is the global system of mobile communication mode, forcing the communication mode in which the wireless network terminal works to be switched to the predetermined communication mode.
