SYSTEMS AND METHODS FOR EFFICIENT TRAFFIC OFFLOAD WITHOUT SERVICE DISRUPTION

摘要

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.
