Abstract

The embodiment of the invention discloses a power supply management method and user equipment and relates to the technical field of electronic information. According to the power supply management method and the user equipment, the frequency of directly reading data from an intelligent card can be reduced and the intelligent card can be at a power-off state for a long time so as to save energy. The method disclosed by the invention comprises the following steps: reading first data in the intelligent card in the user equipment and storing the read first data into a memorizer in the user equipment to be used as mirror image data, thus conveniently utilizing the mirror image data to be subjected to data interaction with a wireless network by the user equipment; and after storing the first data into the memorizer in the user equipment to be used as the mirror image data, enabling the intelligent card to be power-off. The power supply management method is good for reducing the power consumption of the user equipment.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a power management method and user equipment. Background technique [0002] Many user devices such as smartphones and PADs currently in use need to be connected to a wireless network to realize most of the communication functions. In practical applications, the user equipment must power on the smart card and read the user data in it to perform information interaction functions with the wireless network such as logging in to the network, receiving service information, etc., wherein the smart card can be a SIM (Subscriber Identity Module, user Identification Module) card, USIM (Universal Subscriber Identity Module, Global Subscriber Identity Module) card, etc. For example: [0003] During the use of the mobile phone, many applications and services need the support of the wireless network, and the necessary data in the SIM card needs to be frequently read to meet th...
