| 20100106969 | DYNAMIC FOREIGN AGENT-HOME SECURITY ASSOCIATION ALLOCATION FOR IP MOBILITY SYSTEMS - The present invention utilizes the AAA infrastructure to dynamically allocate the various parameters needed to establish the security association between the Foreign Agent and the Home Agent. The present invention uses the AAA server as a central entity to dynamically generate and distribute the chosen security association parameters needed to support the Foreign Agent and Home Agent security association based on a request from the Foreign Agent. The AAA server can also dynamically assigns a unique SPI value to the Foreign Agent and Home Agent pairs. The various parameters that can be allocated in the present invention include a FA-HA shared secret key or a public/private key pair, an authentication algorithm and mode, a FA-HA secret key lifetime, and security parameter index or security index values. The present invention also can assist in making sure that the Foreign Agent and the Home Agent stay synchronized with respect to their security association. | 04-29-2010 |
| 20100110957 | NEGOTIATING DIFFERENT MOBILE IP DELIVERY STYLES - The present invention provides a system and method to selectively negotiate different delivery styles for different types of packets sent from the Mobile Node to the Foreign Agent, which will allow the Mobile Node to negotiate a delivery style that will permit the Foreign Agent to transmit certain selected outbound traffic directly without reverse tunneling that traffic back to the home network. Specifically, the present invention allows the Foreign Agent to distinguish between certain types of BC/MC packets that are designated to be processed and routed to their destinations by the Foreign Network directly, as opposed to reverse tunneling the outbound traffic from the Foreign Agent back to the Home Agent on the home network. By selecting processing by the Foreign Network, the efficiency of the system will improve because the transmission of outbound traffic and inbound responses will not need to be tunneled through the Home Network. | 05-06-2010 |
| 20100220627 | Enhanced Encapsulation Mechanism using GRE Protocol - Wireless gateway nodes are enabled to support mobile node services, such as content based billing, when a data treatment server is present in the system. Using one of a defined Content Flow Label (CFL), an Application Program Interface (API), and a compression protocol header, content based billing is provided such as by exchanging content and byte count information with the data treatment server. | 09-02-2010 |
| 20100254347 | Support for Continuity of Tunnel Communications for Mobile Nodes Having Multiple Care of Addressing - The present invention solves communication disruption problems during the hand-off transition period by using a pre-handoff registration of a new foreign agent on behalf of the mobile node The pre-handoff registration message should: (1) identify itself as a pre-hand off registration message, (2) indicate direction of traffic for the pre-handoff registration time period, and (3) specify a lifetime or time period when the pre-handoff registration request will continue to be considered valid The local mobility anchor will accept traffic using the pre-handoff registration care-of address depending on the directionality indicator, but the communication traffic to or from the mobile node will not be disrupted during the transition period. Because the care-of address for the mobile node on the new foreign network can be used to direct communication traffic to or from the mobile node during this transition time period, no disruption of service will be encountered. | 10-07-2010 |
| 20100272061 | Support for Multi-Homing Protocols - The present invention solves these problems with a new proxy binding update request and proxy binding acknowledgment messages having new indicators and identification information. Namely, the home agent/local mobility anchor will exchange proxy binding update messages and proxy binding acknowledge messages that include information such as mobile node identification (MN-ID), home network prefix (HNP), but can also include selective information fields such as, access type, handover indicator (HO), and interface identification (interface ID) By including new access type, indicator, and identification information, the local mobility anchor can respond to a binding update request message with a better understanding of the new connectivity request from the mobile node. | 10-28-2010 |
| 20100290621 | TUNNELING SUPPORT FOR MOBILE IP USING A KEY FOR FLOW IDENTIFICATION - In a network that supports mobility of a mobile node, a tunnel between a first mobility node and a second mobility node is established in the network. The established tunnel is according to a tunneling protocol (e.g., Generic Routing Encapsulation tunneling protocol) that uses at least one key ( | 11-18-2010 |
| 20100332821 | Mobile IP Over VPN Communication Protocol - The present invention supports a communication protocol for transmission of information packets between a mobile node and a virtual private network. Information packets are encapsulated and decapsulated along the route as the information packet is forwarded among the various networks on its path to the destination address; either the mobile node on a foreign network or a correspondence node on a virtual private network. A home agent on the virtual private network supports transmitting the information packets, and the information packets are transmitted from the virtual private network from the home agent or a virtual private network gateway. | 12-30-2010 |
| 20110007711 | Support for Multi-Homing Protocols Using Transient Registration and Expanded Binding Revocation Messages - The present invention solves these problems with a new proxy binding update request and proxy binding acknowledgement messages having new indicators and identification information. Namely, the home agent/local mobility anchor will exchange proxy binding update messages and proxy binding acknowledge messages that include information such as mobile node identification (MN-ID), home network prefix (HNP), but can also include selective information fields such as, access type, handover indicator (HO), and interface identification (interface ID). By including new access type, indicator, and identification information, the local mobility anchor can respond to a binding update request message with a better understanding of the new connectivity request from the mobile node. The invention also includes a binding revocation message with expanded trigger field information sent from the local mobility anchor to the mobile access gateways. | 01-13-2011 |
| 20110040886 | Method and System for Identification of Packet Gateways Supporting Different Service Types - The present invention provides a method and system for identification of the different packet gateways that support different types of services on their packet data networks. The method and system provides identification and addressing information to user equipment for one or more packet gateways that support different types of services, sometimes called QoS services. The identification and addressing information for the one or more packet gateways is provided in the present invention by and through a DNS server or an AAA server depending on the network architecture and the IP version supporting the communications with the mobile node. | 02-17-2011 |
| 20110090851 | Method and System for Transmission of Fragmented Packets on a Packet-Based Communication Network - The present invention provides a method and system for the identification and discovery of the lowest maximum transmission unit (MTU) size for transmission packets on some or all of the transmission path nodes. Different methods and protocols are described in the present patent application to support the identification and discovery of the lowest maximum transmission unit (MTU) size for fragmented transmission packets. | 04-21-2011 |
| 20110122824 | ANCHORING SERVICES OF A MOBILE STATION ATTACHED TO A FIRST SERVICE DOMAIN AT A HOME AGENT IN A SECOND SERVICE DOMAIN - A first node receives information associated with a mobile station to allow for establishment of a session for the mobile station that is attached to a first wireless access network in a first service domain. In response to the received information, the first node sends messaging to a home agent in a second service domain that is of a different type than the first service domain. The first node receives, from the home agent, an Internet Protocol (IP) address allocated to the mobile station in the second service domain, where the IP address is allocated in response to the messaging, and where services provided to the mobile station are anchored in the second service domain. | 05-26-2011 |
