Methods and systems are provided for secure Mobile-IP traffic traversing network address translation (NAT). A virtual-private-network (VPN) tunnel extending between the mobile node and the home agent is established, wherein the home agent comprises a VPN function. Establishing the VPN tunnel comprises (i) the mobile node communicating with the home agent at a public address of the home agent via a private network, a NAT device, and a public network and (ii) the home agent assigning the mobile node a first public address. The mobile node is registered with the home agent. Registering the mobile node comprises (i) the mobile node communicating via the VPN tunnel with the home agent at the public address of the home agent and (ii) establishing the first public address as a home address for the mobile node for, for example, purposes of Mobile-IP communication.

A method, system, and computer-readable media are provided for writing provisioning parameters to a device. In a first aspect, a set of computer-readable media provide a method that includes receiving a request for access onto a communication network from a device. Attributes about the device are retrieved from a first database that details the capabilities of the device. One of the attributes may identify the device a being capable of being provisioned via Open Mobile Alliance protocol, wherein the first database sends a request to a second database to retrieve a tree structure of the device. The tree structure is populated with one or more provisioning parameters, and the populated tree structure is written to the device.

When a mobile node hands off to a new network access server/foreign agent (NAS/FA) and establishes a data link layer connection with the new NAS/FA, the NAS/FA will determine whether the mobile node is registered with a preferred home agent. If not, the NAS/FA will force the mobile node to hand off to the preferred home agent, while maintaining the data link layer connection with the mobile node.

A method, system, and computer-readable medium are provided for maintaining a network session between a network element and a network despite the need to reauthenticate the network element. A computer-implemented method is provided for authenticating a network element to a network. According to this method, an authentication request is transmitted to the network element. In response, the network element provides identifying information for a home agent that previously routed messages to the network element. The identifying information is then used to generate a mobility key. Later, when a network registration request message is received on behalf of the network element, the generated key is used to validate the request.

A method, system, and computer-readable medium are provided for efficiently providing network services to client devices based on the network traffic to be communicated between the device and the network. A system is provided that includes a number of home agents configured to provide network services to mobile nodes. The system is configured in such a way that at least one of the mobile nodes may be served by more than one of the home agents. Thereby, for example, a certain mobile node may be provided voice service via one home agent and email messages via another.

摘要:
A system and a method for enabling network communications between mobile client devices and home networks without regard to the access technology employed by the mobile client device. A system is provided that includes a plurality of mobile nodes configured to communicate over a network using different access technologies. Some of the mobile nodes, for example, may communicate using CDMA. Others may communicate using WiMAX. Still others may use other access technologies. The system also includes a foreign agent. The foreign agent is configured to provide foreign agent services to mobile nodes using different access technologies.

The present invention provides systems and methods for notifying mobile devices of the presence of software and/or firmware updates using Mobile-IP extensions. When a mobile device seeks to engage in a Mobile-IP session, it sends a Mobile-IP registration request message. When it receives a reply to the registration request, the reply includes a Mobile-IP extension that indicates whether an update is available for the mobile device. If the extension indicates that an update is available, the mobile device responsively obtains the update.

A method, system, and computer-readable media are provided for determining connection needs of a mobile device connecting to a wireless network. In one aspect, the computer-readable media provide a method that includes receiving a request from a mobile device to access a wireless network, and performing an authentication phase related to the mobile device attempting to access the wireless network. Furthermore, the method includes evaluating signaling behavior of the mobile device during the authentication phase to determine which access technology from a plurality of types of access technologies to use to connect the mobile device to the wireless network. Moreover, the method includes connecting the mobile device to the wireless network using the determined access technology.
