Abstract: An example method for targeted service request for small data communication in a network environment is provided and includes receiving an extended service request indicating an evolved packet system (EPS) bearer identity for small data communication over a packet data network connection including one or more EPS bearers, where the one or more EPS bearers includes at least one small data bearer configured for small data communication, selectively activating the small data bearer, and facilitating the small data communication. In specific embodiments, the one or more EPS bearers includes a default EPS bearer and one or more dedicated EPS bearers, where the small data bearer is the default EPS bearer. In other embodiments, the one or more EPS bearers includes a default EPS bearer and one or more dedicated EPS bearers, where the small data bearer is one of the dedicated EPS bearers.

Abstract: A method is provided in one example embodiment and includes communicating a plurality of queries associated with common tracking areas in a wireless network; identifying a set of serving gateways that serve the common tracking areas; generating a tracking area identity (TAI) list to be used in provisioning network resources for user equipment; and selecting a first serving gateway from the set of serving gateways for the user equipment, wherein the first serving gateway is selected based on the common tracking areas served by the set of serving gateways. In more specific embodiments, the queries are domain name system (DNS) queries that are supported by a network element and that have no cached DNS response.
