摘要： Methods and apparatus for authenticating a mobile node are disclosed. A server is configured to provide a plurality of security associations associated with a plurality of mobile nodes. A packet identifying a mobile node may then be sent to the server from a network device such as a Home Agent. A security association for the mobile node identified in the packet may then be obtained from the server. The security association may be sent to the network device to permit authentication of the mobile node. Alternatively, authentication of the mobile node may be performed at the server by applying the security association.

摘要： Methods and apparatus for performing registration on behalf of a session associated with a mobile node are disclosed. The mobile node composes a registration request including a NAI identifying a userID and a sub-NAI that uniquely identifies a session associated with the NAI. The mobile node then sends the registration request. When the Home Agent authenticates the mobile node, the Home Agent returns an IP address associated with the session. The NAI and sub-NAI may then be mapped to this IP address in a mobility binding table associated with the Home Agent as well as a visitor table associated with the Foreign Agent to which the mobile node has roamed.

摘要： Methods and apparatus for enabling a node that does not support Mobile IP to roam from a first Foreign Agent to a second Foreign Agent are disclosed. In a Foreign Agent that supports Mobile IP, a method of registering a node that does not support Mobile IP with a Home Agent that supports Mobile IP includes detecting a node in a vicinity of the Foreign Agent, composing a registration request specifying a node ID associated with the node, and sending the registration request to the Home Agent. When the Home Agent receives the registration request from a first Foreign Agent, the Home Agent updates a mobility binding table to associate the first Foreign Agent with the node. In addition, the Home Agent notifies a second Foreign Agent to update its visitor table to reflect roaming of the node from the second Foreign Agent to the first Foreign Agent.

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 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.

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.
