Problems solved by technology

At this time, the system RAM cannot be powered off during DRX / eDRX, which increases power consumption
[0006] (2) When the system RAM is powered off and DRX / eDRX is woken up, it consumes CPU time and increases power consumption when executing software processes such as system boot, operating system, protocol stack, and physical layer initialization.

Abstract

The invention discloses a control method of an Internet of Things chip based on a cellular technology, which comprises the following steps: when in a low power consumption mode, a wake-up circuit catches a wake-up event, the system hardware in a power-down state is awakened and enters a solidification start program; a system boot program is started in combination with a boot reason of the boot program, the system boot program analyzes the validity of a paging message corresponding to the wake-up event; When the paging message is a validity message, the system core software is started to process the paging message; When the paging message is an invalidation message, the system boot program re-enters a low power mode. After the invention captures the wake-up event, the system hardware is awakened, and the whole system is started only when it is confirmed that the paging message is valid to be processed. Compared with the traditional low power mode, it saves more power. So that pow consumption is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a control method of an Internet of Things chip based on cellular technology and an Internet of Things chip based on cellular technology. Background technique [0002] Low power consumption is an important performance index of IoT chips based on cellular technology. Such devices are powered by batteries, which require a battery life of 10 years. In order to reduce power consumption, 3GPP introduced eDRX and PSM modes on the basis of the original DRX to achieve power saving. [0003] In PSM mode, the chip completely shuts down downlink reception, which can achieve the lowest power consumption. In DRX / eDRX mode, it should be started periodically to receive paging messages sent by the network side. [0004] In the traditional DRX / eDRX mode, the UE needs to be woken up regularly to detect paging messages on the network side, which are divided into the fol...
