SESSION ESTABLISHMENT IN A WIRELESS NETWORK IN VIEW OF INTERFACE FAILURE

Abstract: a method includes detecting, using a session management function (smf) at a core network component, an n4 session failure between the smf and a user plane function (upf) at the core network component, initiating, using the smf, a timer for establishing an n4 session between the smf and the upf, maintaining, using the smf, a user equipment connected to a network in an idle state while the timer is active, attempting, using the smf, to establish the n4 session while the timer is active, and bringing, using the smf, the user equipment back to an active state after the n4 session is established.
