    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.
