AI Technical Summary

Technical Problem

Existing RRC states in 4G and 5G communication systems, including the idle and inactive states, result in unnecessary power consumption due to the reception of synchronization, paging, and RRM measurements, which cannot be effectively reduced.

Method used

Introduce a new terminal state, referred to as the sleep state, with reduced communication power consumption, and define conditions for transitioning between states based on wake-up signals, timer expiration, device changes, and signal quality thresholds to minimize power usage while ensuring reliable communication.

Benefits of technology

Significantly reduces terminal power consumption by minimizing reception of synchronization and measurement activities, achieving power-saving objectives while maintaining reliable communication quality.

Abstract

The present application discloses a terminal state switching method, device, and terminal, which includes a step of switching a terminal in a first state to a second state when a first condition is satisfied, the second state being an idle state, a connected state, or an inactive state, and the communication power consumption of the terminal in the first state being lower than the communication power consumption of the terminal in the second state.
