Abstract
Some embodiments provide methods for selecting a serving gateway, including: receiving a message from a base transceiver station including a list of tracking areas handled by the base transceiver station; performing a domain name system query for at least one tracking area to retrieve and store in a local memory information identifying a serving gateway serving the at least one tracking area; receiving an attach request from the base transceiver station identifying the user equipment and a tracking area from which the user equipment is connected to the network; searching the information identifying a serving gateway serving the at least one tracking area stored in the local memory to identify a serving gateway to service the user equipment based on the tracking area from which the user equipment is connected to the network; and sending a message identifying the identified serving gateway to the base transceiver station.
