AI Technical Summary

Technical Problem

In multi-path relay scenario, when the relay terminal device is in the RRC idle state or the RRC inactive state, how to effectively trigger it to enter the RRC connected state, solves the service interruption or in the path management scenario when the relay terminal device is added or changed. The problem of rate reduction.

Method used

By receiving the RRC reconfiguration message sent by the network side device, a first signaling message is sent to the relay terminal device, including a PC5-RRC message or an RRC reconfiguration completion message, to trigger the relay terminal device in the RRC idle state to execute RRC The relay terminal device that is connected to the establishment of the connection or is in the RRC inactive state performs RRC connection recovery.

Benefits of technology

It realizes that while ensuring flexible network configuration, it promptly triggers the relay terminal equipment to enter the RRC connection state, reduces end-to-end delay, avoids service interruption or rate reduction in non-direct connection path changes, and improves network throughput and user experience. .

Abstract

A method for triggering a relay terminal device to enter RRC_CONNECTED. The method comprises: receiving a radio resource control (RRC) reconfiguration message sent by a network-side device; and sending a first signaling message to a relay terminal device, wherein the first signaling message is used for triggering the relay terminal device in RRC_IDLE to execute RRC connection establishment or triggering the relay terminal device in RRC_INACTIVE to execute RRC connection resume. The present disclosure ensures the flexible configuration of a network and also triggers, in a timely manner, the relay terminal device to enter RRC_CONNECTED, thus achieving a multi-path communication function, reducing end-to-end delay, avoiding the problem of service interruption or a rate reduction in a scenario in which an indirect path changes, improving the network throughput and reliability, and improving the user experience.
