Abstract: An access and mobility management function (AMF) of a 5G mobile network receives an uplink non-access stratum (NAS) transport message through a source gNB and that is associated with a user equipment (UE). From this message, the AMF identifies a tracking area identity (TAI) of a first tracking area. During a handover process associated with the UE, the AMF receives a new message that indicates a new TAI for the new tracking area the UE is entering. Using the TAI of the first tracking area and the TAI of the new tracking area, the AMF identifies a new tracking area adjacency. With this new tracking area adjacency, the AMF automatically updates TAI lists to incorporate the new tracking area adjacency.
