20080198810 | METHODS AND APPARATUS FOR BROADCAST OPTIMIZATION IN MOBILE IP - Methods and apparatus for supporting broadcast traffic in Mobile IP are disclosed. When a Mobile Node registers via a Foreign Agent supporting Mobile IP, the Foreign Agent receives a registration request from a Mobile Node and sends the registration request to a Home Agent. A registration reply received from the Home Agent has a network mask extension including a network mask associated with the home address of the Mobile Node. The Foreign Agent then sends the registration reply to the Mobile Node. Alternatively, the Mobile Node may register via a collocated care-of address, in which case the registration reply is received directly from the Home Agent. Once the Mobile Node has obtained its network mask, it may send packets such as broadcast packets, as well as roam to its Home Agent. Additionally, in accordance with various embodiments, the Foreign Agent duplicates broadcast packets for transmission to Mobile Nodes, rather than receiving the duplicated packets from the Home Agent. In this manner, broadcast traffic in a Mobile IP environment is optimized. | 08-21-2008 |
20090080370 | Methods and apparatus for home agent discovery in mobile IP using link state advertisements - In one embodiment, an apparatus receives an advertisement from each of one or more Home Agents, the advertisement including a first set of information associated with a corresponding one of the Home Agents, each advertisement being in a first protocol. The apparatus obtains the first set of information associated with a corresponding one of the Home Agents from each advertisement. The apparatus composes a router advertisement including a second set of information associated with at least one of the Home Agents, the router advertisement being in a second protocol. The apparatus then sends the router advertisement. | 03-26-2009 |
20090300217 | METHOD AND APPARATUS FOR DYNAMICALLY ASSIGNING UNIQUE ADDRESSES TO ENDPOINTS - The present disclosure generally provides techniques for establishing a unique, ephemeral home address (hoa)/home agent address (ha′) address pair that may be limited to use in a session having a defined lifetime. Limiting the use of this dynamic address pair to a session lifetime and by preventing a mobile node from knowing the static address of a home agent may help protect the home agent from attacks. | 12-03-2009 |
20100088400 | INTERNET PROTOCOL ADDRESS MANAGEMENT FOR COMMUNICATING PACKETS IN A NETWORK ENVIRONMENT - A method is provided in one example implementation and the method includes identifying through a home bearer manager that an Internet Protocol (IP) address has been previously sent to an access terminal, the IP address being issued by a visited bearer manager as a result of the access terminal requesting registration in a visited network. The method further includes communicating the IP address to the access terminal in response to the access terminal registering in a home network. The registrations in the home and the visited network allow a plurality of packets to be communicated to the access terminal via the IP address. In more specific embodiments, the IP address serves as a care of address (CoA) address and a home IP address concurrently. The IP address can be exchanged via a mobile IP (MIP) exchange. The home and visited bearer managers are independent or interdependent. | 04-08-2010 |
20120047263 | ATTRIBUTE DRIVEN MOBILE SERVICE CONTROL LOGIC - The disclosed embodiments enable service policies to be provisioned for a Mobile Node dynamically. A network device receives a message including at least one of one or more attributes of a Mobile IP session and one or more user preferences associated with the Mobile Node. One or more rules to be applied to the Mobile Node may then be identified. One or more of the identified rules are executed according to at least one of one or more of the attributes of the Mobile IP session and one or more of the user preferences associated with the Mobile Node. | 02-23-2012 |
20120250509 | SOFT RETENTION FOR CALL ADMISSION CONTROL IN COMMUNICATION NETWORKS - Systems and methods are disclosed for receiving a request at a packet gateway to allocate a new bearer for a mobile device on a wireless telecommunications network; identifying, at the packet gateway, existing bearers that have a quality of service (QoS) that can be reduced without dropping the existing bearers; reducing, at the packet gateway, the QoS of the existing bearers; reclaiming resources at the packet gateway that were previously in use by the existing bearers; and allocating the new bearer for the mobile device using the reclaimed resources at the packet gateway without causing any of the existing bearers to be disconnected, wherein the existing bearers have a lower priority than the new bearer, and wherein the existing bearers have previously been designated as capable of being preempted. | 10-04-2012 |
20130142182 | MOBILITY IN MULTI-DEVICE MULTI-HOMED DEPLOYMENTS - Systems and methods for providing identity management and mobility management are disclosed. The management scheme provides mobility in multi-device and multi-homed deployments. A collection of three identities, a device identity, a link layer identity, and a user identity, can be used to provide mobility for a number of devices under different use scenarios. In one embodiment, a method is disclosed for receiving messages from a mobile device at a mobility gateway, the messages including identifiers such as a user identifier, a link layer identifier, and a device identifier where identifiers are stored or retained at the mobility gateway. When a subsequent network attach request is received including one or more identifiers, a reconnection can occur, based on a result of comparing the stored identifiers with the received one or more identifiers. | 06-06-2013 |
20150029935 | METHODS AND APPARATUS FOR HOME AGENT DISCOVERY IN MOBILE IP USING LINK STATE ADVERTISEMENTS - In one embodiment, an apparatus receives an advertisement from each of one or more Home Agents, the advertisement including a first set of information associated with a corresponding one of the Home Agents, each advertisement being in a first protocol. The apparatus obtains the first set of information associated with a corresponding one of the Home Agents from each advertisement. The apparatus composes a router advertisement including a second set of information associated with at least one of the Home Agents, the router advertisement being in a second protocol. The apparatus then sends the router advertisement. | 01-29-2015 |
