Claim Text:
1. A method of wireless communication for establishing packet connectivity for local packet data network (PDN) traffic, comprising: receiving, by a network entity, an electronic message comprising a request for a PDN connection; determining whether the request for the PDN connection is a local PDN request by at least comparing an access point name (an APN) associated with the request for the PDN connection to a list of local APN names; identifying a local gateway (L-GW) associated with the local PDN request by at least determining whether an Internet protocol (IP) address of the L-GW is indicated in the request, if the PDN connection is determined to be the local PDN request; and initiating a domain name server (DNS) query to obtain the IP address of the L-GW in response to detecting a failure in identifying the L-GW.
