Abstract: Methods and systems for managing AMF re-allocation is provided. The method for managing AMF reallocation during UE registration procedure with a 5G network comprises: determining if the first AMF may send a routing assistance information to the UE, on the first AMF determining that the first AMF is not a right AMF to serve the UE; sending a routing assistance information, to the UE, as response to a first registration request message; receiving routing assistance information from the first AMF; sending a second registration request message to a 5G RAN of the 5G network comprising a portion of content included in the routing assistance information; and routing the second registration request message to a second AMF of the 5G network, wherein the second AMF is determined by the 5G RAN based on the portion of content included in the routing assistance information.

Abstract: Embodiments herein achieve a method for handling registration and session management in a wireless communication system. The method includes registering, by a User Equipment (UE), with a first core network entity over a 3GPP access network and a non-3GPP access network. Further, the method includes triggering, by the UE, a registration procedure to a second core network over the 3GPP access network when a periodic timer of the UE expires in an OOS state. Further, the method includes receiving, by the UE, a non-access stratum (NAS) message, over the 3GPP access network, with an indication to register for the non-3GPP access network with the second core network entity. Further, the method includes reinitiating the registration procedure to register again for the non-3GPP access with the second core network entity through the non-3GPP access network.
