Abstract
Methods, systems, and devices for offloading traffic flows without service disruption are disclosed herein. User equipment (UE) is configured to receive an indication that a current packet data network (PDN) connection can be optimized. The current PDN connection is established over a first PDN gateway (PGW). The UE requests connection over a new PDN connection to a same type of service as the current PDN connection without releasing the connection over the first PGW. The UE routes new traffic flows over a second PGW corresponding to the new PDN connection and routes old traffic flows over the first PGW.
