1. A private network Local Traffic Off-load (LTO) system comprising:
a) a gateway configured to:
i. communicate with a non-private network;
ii. communicate with a BS/AP within a private network that is in wireless communication with a user equipment (UE);
iii. detect a request by the UE for service from the non-private network; and
iv. route the request for service from the BS/AP to the non-private network to allow the UE to register with the non-private network; and
b) an LTO module coupled to the gateway, the LTO module configured to;
i. receive packets from the gateway that were communicated to the gateway by the UE;
ii. identify and maintain within the LTO module, an internet protocol (IP) address of the UE assigned by the non-private network;
iii. recognize a Domain Name System (DNS) query originating from the UE is a request for access to services associated with the private network;
iv. route the DNS query to the private network;
v. receive from the private network a responsive IP address;
vi. respond to the UE DNS request by providing the responsive IP address to the UE through the BS/AP; and
vii. route to the private network, requests from the UE that: (1) have the responsive IP address; and (2) were received from the UE, as determined by the IP address of the UE assigned by the non-private network.
