Problems solved by technology

The 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) standard is studying the use of cellular networks to carry NB-IoT and eMTC services, but the characteristics of services carried by traditional cellular networks are quite different from those of NB-IoT and eMTC services
(1) In the PSM state, the IoT terminal is in a deep sleep state (the deep sleep current is 0.005mA, the most power-saving), the IoT terminal is still registered on the network, but the signaling

Abstract

The invention discloses an Internet-of-things terminal, a system and a wake-up method for the Internet-of-things terminal, which relate to the technical field of the Internet of things. The Internet-of-things terminal includes a wake-up module and a main module. The wake-up module is used for receiving an external wake-up signal from a network-side device, detecting wake-up processing informationfor the main module of the Internet-of-things terminal after processing the received external wake-up signal, generating an internal wake-up signal according to the wake-up processing information andsending the internal wake-up signal to the main module. The main module is used for changing into a light sleep state or a service connection state from a deep sleep state after receiving the internalwake-up signal, so as to receive paging information or downlink data or to carry out cell reselection. Wake-up operation on the main module is realized, and the main module can receive network pagingor downlink data or carry out cell reselection in time even in deep sleep.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to an Internet of Things terminal, a system and a wake-up method for the Internet of Things terminal. Background technique [0002] It is predicted that the number of IoT terminal connections will reach 5 billion by 2020. Operators urgently need to develop new business growth points to cope with the increasingly saturated situation of traditional human-to-human communications. The Internet of Things has become a research hotspot in recent years. [0003] Currently, CIoT (Cellular IoT, cellular Internet of Things) exists in the existing technology, including NB-IoT (NarrowBand Internet of Things, narrowband Internet of Things), eMTC (enhanced Machine Type Communication, enhanced machine type communication), etc. The 3GPP (3rd Generation Partnership Project) standard is studying the use of cellular networks to carry NB-IoT and eMTC services, but the characteris...
