摘要
A user equipment UE context is stored in a local memory including a session context for a breakout data session. The session context comprises a source internet protocol IP address, a destination IP address, an identifier of a former local breakout gateway LBGW and an identifier of a new LBGW. The former LBGW receives first traffic originating from the destination IP address and addressed to the source IP address, and uses the session context to forward the first traffic from the former LBGW to the new LBGW via a first tunnel. There is thus a globally routable IP address for the session context that need not change when the UE moves from one LBGW to another. Embodiments are detailed for routing through more than two LBGWs, and for when the UE initiates another breakout data session on the new LBGW ion addition to the aforesaid breakout data session.
