摘要： Multi-operator networking techniques are provided for allowing two or more operators to share a wireless local area network (WLAN). In particular, mobile access gateway functionality is integrated in a wireless network controller of a WLAN that is accessible to first and second operators. Operator-specific tunnels are created through the network for each of the first and second operators that link a core network of each of the first and second operators with an associated client device. Packets are then forwarded between the core networks of the first and second operators and their associated client devices via the operator-specific tunnels.

摘要： 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.

摘要： A method is provided in one example embodiment and includes receiving a data packet transported on a backhaul link at a first network element; 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; performing a network address translation on the data packet; and offloading the data packet from the backhaul link. In certain implementations, 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 instances, the method can include identifying that the data packet is a downstream data packet; and restoring a tunnel header and tunnel identification based on an IP address of the data packet.

摘要： A method is provided in one example embodiment and includes communicating an access request to an authentication, authorization, and accounting (AAA) element. The access request is configured to include an attribute that indicates that a network element can support a particular home agent assignment from amongst a plurality of home agents. The method also includes receiving a response that includes an Internet Protocol (IP) address of a home agent loadbalancer, the response including a key that establishes a secure connection between the network element and the home agent loadbalancer. In other embodiments, the method includes communicating with a foreign agent in order to authenticate user equipment associated with the access request. In addition, the access request can be initiated by user equipment configured to establish a network communication session via the particular home agent.

摘要： A method and implementation are disclosed for binding a mobile node to a subnet. The invention comprises steps and implementations for intercepting messages sent by a mobile node to a server, associating a predetermined subnet with the intercepted messages and forwarding the intercepted messages to the server. The invention intercepts reply messages sent by at least one server and selects reply messages that are associated with the predetermined subnet. The selected reply messages are forwarded to the mobile node, and reply messages that are not associated with the predetermined subnet are discarded.

摘要： An example method includes receiving a packet for a flow associated with a subscriber; determining if a home agent element has a context for the flow by communicating a handover query to a network element; assigning an Internet protocol (IP) address for the subscriber in response to the home agent element not having the context for the flow; and creating a session for the subscriber, where the session is created using inter-process communication between the home agent element and the network element. The method can further include maintaining communications with a packet data serving node (PDSN) and an Authentication, Authorization, and Accounting (AAA) element in order to assist in roaming between a Long Term Evolution (LTE) network and a code division multiple access (CDMA) network. The inter-process communication is used to maintain the session for the subscriber when the subscriber is attached to different networks.
