Title: METHOD AND APPARATUS FOR MANAGING DATA COMMUNICATION IN WIRELESS COMMUNICATION NETWORK
Abstract:
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments herein disclose a UE for managing a data communication in a wireless communication network. The UE includes a DRB management unit configured to determine a DRB for transmitting a packet based on QoS flow identifier and a PDU session associated with the packet and mapping of the QoS flow identifiers to the DRBs for each established PDU session. The DRB management unit performs one of mapping the packet to an established non-default DRB if the list of one or more QoS flow identifiers associated with the DRB includes the QoS flow identifier of the packet and the DRB is associated with the PDU session of the packet, and mapping the packet to a default DRB associated with the PDU session of the packet if none of the established non-default DRBs is associated with the PDU session and the QoS flow identifier of the packet.
