  • Patent number: 10588044
    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.

  • Patent number: 9397940
    Abstract: An example method is provided and includes receiving a packet associated with a flow, determining a tunnel identifier for the flow, and determining a flow identifier for the flow. The method includes associating the flow identifier and the tunnel identifier to an Internet protocol (IP) address to generate a binding to be used for a network address and port translation (NAPT). In other embodiments, a routing decision is executed based on the binding between the identifiers and the IP address. The flow identifier can be a context identifier (CID), and the tunnel identifier can be a softwire tunnel ID. In yet other embodiments, the packet can be tagged as part of an encapsulation operation, which includes providing information about a network location at which the network address and port translation is to be executed.

  • Patent number: 9215588
    Abstract: An example method includes receiving a message related to a bearer or an Internet Protocol (IP) flow, the message includes an extension indicating whether an Internet Protocol security (IPsec) feature is designated for the bearer or the IP flow. The method further includes mapping a communication flow to the bearer or the IP flow, and applying the IPsec feature to the bearer or the IP flow. In other embodiments, the method can include communicating the extension to a next destination, and updating a security policy to indicate that the bearer or the IP flow is designated for the IPsec feature. In yet other embodiments, an Internet Key Exchange (IKE) is used to establish a security association for a serving gateway associated with the communication flow. The extension is provided at an IP flow level or at a bearer level such that network traffic is designated for the IPsec feature.

  • Patent number: 9049046
    Abstract: A method is provided in one example embodiment and includes communicating an in-band message packet from a first network element; receiving a response to the in-band message from a second network element, the response contains tunnel identification binding data that identifies a tunnel on a backhaul link on which traffic from a user equipment can flow; and receiving instructions from the second network element to offload a received data packet from the backhaul link. In particular instances, the in-band message is set to loopback when the in-band message is sent from the first network element. In other embodiments, the tunnel identification binding data is provided in the payload of the in-band message when the in-band message is sent from the first network element. In other examples, the method can include receiving an assigned Internet protocol (IP) address of the user equipment in the response to the in-band message.

  • Patent number: 9030991
    Abstract: A method is provided in one example embodiment and includes receiving a downstream data packet transported on a backhaul link at a first network element, the downstream data packet is associated with a user equipment; identifying whether a downstream tunnel used to communicate the data packet to the user equipment has become dormant; and communicating an in-band message to a second network element that the downstream tunnel is dormant. In other examples, the method can include dropping the data packet when a network address port translation binding has expired or does not exist. In certain implementations, the method can include identifying the downstream tunnel as dormant when an activity timer has expired, or identifying the downstream tunnel as dormant based on a stale state setting.

  • Patent number: 9031038
    Abstract: A method is provided in one example embodiment and includes receiving a data packet over a first link at a first network element; establishing an out-of-band channel over a second link between the first network element and a second network element; and receiving instructions at the first network element to offload the data packet from the first link. In more particular embodiments, the first network element is a mobile enabled router, and the second network element is a gateway general packet radio service support node or a packet data network gateway. The method can also include receiving a discovery message from the second network element, the discovery message triggering the establishment of the out-of-band channel. In certain cases, the data packet is offloaded based on a type of data in the data packet.

  • Patent number: 8942112
    Abstract: A method is provided in one example embodiment and includes invoking a mobile access gateway function based on an end user requesting an Internet Protocol (IP) address in a wireless or a wireline network. The invocation is selective such that the mobile access gateway function is invoked if the end user requires IP mobility services. The method also includes communicating with a gateway in order to obtain the IP address. The mobile access gateway function is coupled to a network element that receives packets for a communications flow from the end user that can conduct the flow through the wireless network and through the wireline network.
