Systems and methods for selecting serving gateways to service user equipment
First Claim
1. A method for selecting a serving gateway to service user equipment in communication with a network, comprising:
- 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, which includes storing the information as at least part of a table of sets of tracking area identities and at least one associated serving gateway; 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.

10. A mobility management entity in a communication network comprising:
-
memory; an interface configured to receive a message from a base transceiver station including a list of tracking areas handled by the base transceiver station, to initiate 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; wherein the mobility management entity is configured to store, in the memory, the information indicating the serving gateway serving the at least one tracking area as at least part of a table of sets of tracking area identities and at least one associated serving gateway, and upon an occurrence of a triggering event, retrieving, from the memory, the stored information indicating the serving gateway serving the at least one tracking area. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
