Title:
METHOD FOR DATA OFFLOADING, METHOD FOR DRB IDENTIFIER ALLOCATING, METHOD FOR RESOURCE RELEASING, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/160298
Kind Code:
A1
Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present application provides a method for establishing dual connectivity to ensure data continuity in 5G architecture. Related information of a mapping of a QoS Flow to a data radio bearer (DRB) is transmitted, by a first node, to a second node; the related information of the mapping carries indication information; response information in response to the information related to the mapping is received from the second node; and based on the response information, data is transmitted to the second node. The method of the present application may correctly configure dual connectivity resources, reduce signaling interaction, avoid configuration conflicts, optimize resource configuration, and improve the reliability of transmitting user data.
