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.

摘要： A method for communicating in a loadbalancing environment is provided that in a particular embodiment includes receiving a request packet from a network access server (NAS) to initiate a communication session. The request packet is then communicated to a tunneling protocol network server (TPNS) and a response packet is received in response to the request packet. The response packet establishes a tunnel that facilitates the communication session and that includes an identification element associated with the TPNS such that a data transfer associated with the communication session is executed between the NAS and the TPNS.

摘要： Communicating packets along a bearer path includes receiving a home network address and a visited network address at an access terminal. The home network address corresponds to a home anchored bearer path anchored at a home network of the access terminal. The visited network address corresponds to a visited anchored bearer path anchored at a visited network. The access terminal determines whether to use the home anchored bearer path or the visited anchored bearer path, and communicates packets using the home network address or the visited network address in accordance with the determination.

摘要： Methods and apparatus for enabling intra-agent mobility by a mobile node are disclosed, thereby permitting a mobile node to register with a Home Agent via a Foreign Agent where the Home Agent and the Foreign Agent are provided in the same router. A method of registering a mobile node visiting a Foreign Agent with a Home Agent includes receiving a registration request packet specifying a Home Address and a care-of address. It is then determined whether the Home Address specified in the registration request packet is equivalent to a Home Agent address associated with the router. In addition, it may be determined whether the care-of address specified in the registration request packet is equivalent to a Foreign Agent address advertised by the router. Alternatively, it may be determined whether the D bit specified in the registration request packet is set and the care-of address specified in the registration request packet is a collocated care-of address. The mobile node may then be registered with the Home Agent through the use of a physical interface on the router rather than creating or specifying a tunnel interface to reach the mobile node or the Home Agent.

摘要： Methods and apparatus for maintaining Mobile IP operation in a Home Agent are disclosed. In a Home Agent, a Mobile Node is registered and a registration entry is created in a mobility binding table for the Mobile Node. A multicast message is then sent to a virtual router group to which the Home Agent belongs and with which the Home Agent shares a virtual IP address. The multicast message notifies the virtual router group of the registration. A similar process may be performed when a Mobile Node is de-registered. When an active or non-active Home Agent is initialized, it sends a multicast mobility binding table request to the redundancy group indicating that bindings are requested. The Home Agent may then receive bindings in response to the request and update its mobility binding table with the received bindings.

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 sending a registration request packet on behalf of a node that supports PPP but does not support Mobile IP is implemented in a Foreign Agent. The method comprises accepting a call from the node and receiving authentication information associated with a PPP authentication protocol from the node, the authentication information enabling a PPP node to be authenticated. From this authentication information, a PPP node profile is obtained. The PPP node profile includes registration information associated with the node that enables proxy registration to be performed by the Foreign Agent on behalf of the node, where the registration information associated with the node identifies a Home Agent associated with the node. The registration information may also include other information that may be pertinent to the composition of a registration request packet. A registration request packet including the registration information associated with the node is then composed and sent to the Home Agent on behalf of the node. The registration request packet that is sent by the Foreign Agent also may include a registration indicator indicating whether registration being performed by the Foreign Agent on behalf of the node is a re-registration by the Foreign Agent or an initial registration by the Foreign Agent. More particularly, in accordance with one embodiment, the registration request packet includes a sequence number indicating an order within a sequence of one or more registrations performed by one or more Foreign Agents on behalf of the node. From the sequence number, a Home Agent receiving the registration request packet may determine whether the Foreign Agent is performing a re-registration or an initial registration on behalf of the node.
摘要翻译：在外部代理中实现代表支持PPP但不支持移动IP的节点发送注册请求分组的方法和装置。该方法包括从节点接受呼叫并从该节点接收与PPP认证协议相关联的认证信息，该认证信息使PPP节点得到认证。从该认证信息获得PPP节点简档。 PPP节点简档包括与节点相关联的注册信息，该注册信息能够由外部代理代表节点执行代理注册，其中与该节点相关联的注册信息标识与该节点相关联的归属代理。注册信息还可以包括可能与注册请求分组的组合相关的其他信息。然后，包括与节点相关联的注册信息的注册请求分组被组合并代表节点发送到归属代理。由外地代理发送的登记请求包也可以包括一个登记指示符，指示外国代理人代表该节点进行的登记是否由外地代理人重新注册或外国代理人的初始登记。更具体地，根据一个实施例，注册请求分组包括指示由一个或多个外部代理代表节点执行的一个或多个注册的序列内的顺序的序列号。从序列号，接收注册请求分组的归属代理可以确定外部代理是否正在代表节点执行重新注册或初始注册。
