System and method for offloading data in a communication system
First Claim
1. A method implemented by a network element, the method comprising:
- receiving a data packet transported on a backhaul link at the network element;
de-capsulating the data packet, if the data packet is an upstream data packet;
performing an identification of whether the data packet matches an internet protocol (IP) access control list (ACL) or a tunnel endpoint identifier;
performing a network address translation on the data packet with the network element, in response to the identification identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier;
offloading the data packet from the backhaul link at the network element in response to the identification identifying that the data packet matches the IP ACL or the tunnel endpoint identifier; and
communicating the data packet from the network element to a gateway or general packet radio service support node using a generic routing encapsulation tunnel in response to the identification identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier.

Abstract
A method is provided in one example embodiment and includes receiving a data packet transported on a backhaul link at a first network element; de-capsulating the data packet; identifying whether the data packet is an upstream data packet; identifying whether the data packet matches an internet protocol (IP) access control list (ACL) or a tunnel endpoint identifier; and offloading the data packet from the backhaul link. In more specific embodiment, the method can include identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier; and communicating the data packet to a second network element. In other examples, the method can include identifying that the data packet is a downstream data packet; identifying a service to be performed for the data packet that cannot be performed at the first network element; and communicating the data packet to a second network element.

6. Logic encoded in one or more non-transitory media that includes code for execution and, when executed by a processor, is operable to perform operations comprising:
-
receiving a data packet transported on a backhaul link at a network element including the processor; de-capsulating the data packet, if the data packet is an upstream data packet; performing an identification of whether the data packet matches an internet protocol (IP) access control list (ACL) or a tunnel endpoint identifier; performing a network address translation on the data packet with the network element, in response to the identification identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier; offloading the data packet from the backhaul link at the network element in response to the identification identifying that the data packet matches the IP ACL or the tunnel endpoint identifier; and communicating the data packet from the network element to a gateway or general packet radio service support node using a generic routing encapsulation tunnel in response to the identification identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier. - View Dependent Claims (7, 8, 9, 10, 17, 18)

11. An apparatus, comprising:
-
a memory element configured to store data; a processor operable to execute instructions associated with the data; and a traffic offload module configured to interface with the memory element and the processor, wherein the apparatus is configured to receive a data packet transported on a backhaul link at the apparatus; de-capsulate the data packet, if the data packet is an upstream data packet; perform an identification of whether the data packet matches an internet protocol (IP) access control list (ACL) or a tunnel endpoint identifier; perform a network address translation on the data packet, in response to the identification identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier; offload the data packet from the backhaul link at the apparatus in response to the identification identifying that the data packet matches the IP ACL or the tunnel endpoint identifier; and communicate the data packet from the apparatus to a gateway or general packet radio service support node using a generic routing encapsulation tunnel in response to the identification identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier. - View Dependent Claims (12, 13, 14, 19, 20)
