Abstract
Description
technical field
[0001] The invention relates to the technical field of wireless communication, in particular to a management method and device for supporting multiple SIM cards to share an RF processor. Background technique
[0002] Dual-card dual-standby terminal refers to a terminal with dual card slots, which can support dual Subscriber Identity Module (SIM, Subscriber Identity Module) cards or dual global Subscriber Identity Module (USIM, Universal Subscriber Identity Module) cards in standby and voice or data under two network standards. Terminal for business. At present, in order to effectively reduce the power consumption, production cost and internal chip area of dual-card dual-standby terminals, a radio frequency (RF, Radio Frequency) channel sharing scheme has been proposed, that is, two cards share one RF processor, such as G( GSM, Global System for Mobile Communications) + G-mode RF channel sharing scheme and W (WCDMA, wideband code division multiple access) +...
