RRC connection configuration method and communication device

Abstract

The invention provides an RRC connection configuration method and a communication device, which can effectively reduce the power consumption of terminal equipment when the terminal equipment is in anRRC connection state and does not receive and transmit data. The method comprises the following steps: terminal equipment receives a first timeout parameter and a second timeout parameter sent by network equipment; wherein the second timeout moment corresponding to the second timeout parameter is later than the first timeout moment corresponding to the first timeout parameter. And then, when the MAC layer of the terminal device detects data transceiving, the terminal device enters or maintains a first working mode in an RRC connection state, and starts or restarts a first timer and a second timer at the same time. And then, when the time of the first timer reaches a first timeout moment, the terminal device enters a second working mode in the RRC connection state, and when the time of thesecond timer reaches a second timeout moment, the terminal device enters an RRC idle state, wherein the power consumption of the terminal equipment in the second working mode is lower than the power consumption of the terminal equipment in the first working mode.

Description

technical field [0001] The present application relates to the communication field, and in particular to a radio resource control RRC connection configuration method and a communication device. Background technique [0002] In the existing 4th generation (4G) and 5th generation (5G) mobile communication systems, such as the long term evolution (long term evolution, LTE) system and the new radio interface (new radio, NR) system, when When there is no data, a terminal device, such as a mobile phone, can jump from a radio resource control (radio resource control, RRC) connected state (RRC_CONNECTED) to an RRC idle state (RRC_IDLE), so as to reduce power consumption of the terminal device. Specifically, the terminal device may jump to the RRC idle state after receiving the RRC connection release signaling sent by the base station, for example, the RRC connection release signaling may be sent by an evolved node (evolved Node B, eNB) of the LTE system RRCConnectionRelease, RRCRele...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 As shown, before the terminal equipment jumps from the RRC connected state to the RRC idle state, that is, before the terminal equipment receives the RRC connection release signaling sent by the base station, or before the data inactivity timer of the terminal equipment expires, the There is a long period of time as follows: the terminal device does not send and receive data, but it is still in the same working state as when sending and receiving data, for example, the radio frequency (radio frequency, RF) circuit of the terminal device is still on, resulting in high power consumption

However, the existing agreement does not specify how to reduce the power consumption during the above time period
