Title:
METHOD AND APPARATUS SUPPORTING LOCAL BREAKOUT IN A DUAL-CONNECTIVITY ARCHITECTURE
Document Type and Number:
WIPO Patent Application WO/2016/117979
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 disclosure provides a method of de-activating a local IP access (LIPA) bearer supporting local breakout in a dual-connectivity architecture. When an MeNB determines to change an SeNB serving a UE or hand the UE over from the MeNB to an eNB, the MeNB may trigger a LIPA bearer de-activation process, and then trigger the process of change the SeNB serving the UE or hand the UE over from the MeNB to the eNB. Various examples also provide another method and an apparatus for de-activating a LIPA bearer, for bearer switch, for establishing a LIPA bearer. The methods and apparatus can establish, switch and correctly release local breakout bearer in a dual-connectivity architecture, so as to reduce the load of a core network of an operator.
