Abstract
Examples pertaining to protocol improvement for redirection to another system in mobile communications are described. An apparatus in a 5Generation System (5GS) receives, from a mobile network, a reject cause indicating that redirection to an Evolved Packet System (EPS) is required. Responsive to receiving the reject cause while no suitable cell of the first mobile network connected to an Evolved Packet Core (EPC) is found or while no cell of the first mobile network connected to an EPC can be selected, the apparatus enters a predefined 5Generation Mobility Management (5GMM) state and starts a timer.
