    摘要: The claimed subject matter relates to performing routing in a wireless communications system. In more detail, each device associated with a wireless packet-switched network may not be aware of an identity and/or address of a particular point of attachment with respect to a wireless terminal. A data packet that should be provided to a particular point of attachment can be initially directed to a wireless terminal or a one-hop multicast address, for instance. Thereafter, the data packet can be encapsulated in a frame format and identity of the particular point of attachment can be provided in such frame. The frame can thereafter be routed to the point of attachment.

    摘要: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.

    摘要: Methods and apparatus for establishing communication links, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described.

    摘要: Embodiments describe synchronizing access routers with wireless terminal state information. According to an embodiment is a wireless terminal that transmits a message that includes an address for at least two access routers. State change information can optionally be included in the message. According to another embodiment is an access router that receives a state change notification from a wireless device or another access router. The state change notification is updated in the access router. An acknowledgment confirming the updated state change may be sent to the wireless terminal. Dynamic state synchronization is provided with minimal communication with wireless terminal.

    摘要: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a end node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff or the use of a core network node to support state transfer. As part of a handoff state information is obtained by an end node from the current access node in encrypted form and then communicated to the new access node to which the handoff operation is to be completed. The new access node, e.g., base station decrypts the state information and then uses it to support communications with the end node. While the information is communicated to and from the end node over wireless links, since it is encrypted by the first access node it is secure and can be trusted by the receiving, e.g., target, access node.

    摘要: A mobile communications system that uses IP packets to transmit data between end nodes, such as mobile devices, is described. In order to facilitate session establishment, maintenance, security, and handoff operations, access nodes through which end nodes communicate with one another include a session signaling server module and a mobility agent module. The session signaling server module may be implemented as a SIP server while the mobility agent module may be implemented using Mobil IP signaling. The mobility agent and SIP server within an access node are identified using a single shared identifier, IP address. The same security method and common secret may be used to provide security with regard to both mobile IP messages and SIP messages. Sessions admission decisions and resource allocation for admitted sessions can also take place internally to the access node of this invention without need for signaling to external elements.
