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.
