Abstract
Various communication systems may benefit from improved network communication setup. A method, in certain embodiments, may include determining at a network entity a new protocol data unit session anchor of a protocol data unit session with a user equipment. The method may also include transmitting from the network entity to the new protocol data unit session anchor a request to establish the new protocol data unit session anchor. In addition, the method may include transmitting an indication from the network entity to a radio access network. The indication may notify the radio access network to switch paths to the new protocol data unit session anchor. Further, the method includes sending from the network entity a gratuitous address resolution protocol request to the determined new packet data unit session anchor. The gratuitous address resolution protocol request may comprise an address of the user equipment in the protocol data unit session.
