  • Patent number: 11129054
    Abstract: The present disclosure discloses methods, systems and devices for supporting local breakout in a small cell architecture. An MME sends information of a local breakout bearer for a UE to a MeNB, and the MeNB determines a local home network to which the local breakout bearer belongs according to the received information. When the MeNB is to switch the local breakout bearer between different eNBs, the MeNB selects an eNB in the local home network to which the local breakout bearer belongs as a target eNB. By the present disclosure, the continuity of local breakout traffic may be ensured when a User Equipment (UE) moves in a small cell scenario, thereby avoiding data loss and improving user experiences. Further, a local breakout bearer may be released timely and reasonably, thereby saving system resources.
