Abstract: Some embodiments disclose a method for providing a tracking area identity list in a communications network. The method includes maintaining a tracking area transition likelihood and a tracking area group transition likelihood, and recording a mobility number and a paging number. The method further includes determining a category associated with the user equipment device based on the recorded mobility number and the recorded paging number, and generating the tracking area identity list for the user equipment device based on the category associated with the user equipment device and one or both of the tracking area transition likelihood and the tracking area group transition likelihood.

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.

Abstract: Some embodiments provide methods for selecting a serving gateway to service user equipment in communication with a network, including: receiving a message from a base transceiver station including a list of tracking areas handled by the base transceiver station, initiating a domain name system query for at least one tracking area in the list of tracking areas to identify information indicating a serving gateway serving the at least one tracking area, storing, in local memory, the information indicating the serving gateway serving the at least one tracking area, and upon an occurrence of a triggering event, retrieving, from the local memory, the stored information indicating the serving gateway serving the at least one tracking area.
