Title:
METHOD, APPARATUS FOR SYNCHRONIZATION OF STATUS OF QOS FLOW IN COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/199397
Kind Code:
A1
Abstract:
The present disclosure relates to a method, an apparatus for a synchronization of a status of a QoS flow in a communication system. A method is performed at a terminal device, for a synchronization of a status of a quality of service, QoS, flow in a communication system. The method comprises: deleting (S101) the QoS flow locally; marking (S102) a status of the QoS flow as being deleted and not synchronized; and transmitting (S103) a protocol data unit, PDU, session modification request to synchronize the status of the QoS flow. According to embodiments of the present disclosure, when the status of the QoS Flow is changed by one of the terminal device or the network side in some scenarios, the status of the QoS Flow can still be synchronized.
