AI Technical Summary

Technical Problem

Existing technologies face challenges in collecting Quality of Experience (QoE) measurement values in the Radio Resource Control Idle (RRC-IDLE) mode of terminal devices, particularly due to the lack of continuity in QoE measurement data when devices transition from connected to idle states, leading to incomplete or lost QoE context information.

Method used

A solution is provided to maintain QoE measurement continuity by transmitting a QoE context identifier and associated information to the terminal device's access stratum during idle mode, allowing retrieval and forwarding of QoE data when the device reconnects, ensuring seamless data collection across network transitions.

Benefits of technology

Ensures continuous QoE measurement data collection and management across RRC idle and connected states, maintaining the integrity of QoE measurements and enabling efficient reporting to the core network.

Abstract

An embodiment of the present disclosure relates to handling a QoE session that remains in RRC-IDLE mode. An access network device determines that a terminal device will perform quality of experience (QoE) measurement collection after disconnection from a first access network device, and based on the terminal device's determination to perform QoE measurement collection after disconnection, transmits a QoE context identifier to the terminal device that identifies QoE context information to be used for QoE measurement collection, and transmits the QoE context identifier and the QoE context information to a core network device. As provided in the present disclosure, the stored QoE report can be transmitted to a new serving gNB and then transmitted to an MCE.
