  • Patent number: 7961683
    Abstract: An active session mobility solution for point-to-point protocol (PPP) in accordance with the present invention provides fast and smooth handoff by reducing tunneling overhead on tunneling mechanisms, such as P-P tunneling from a serving Source (e.g., a PPP termination device) to a new serving Target (e.g., a PPP termination device). In the active session mobility solution of the present invention, PPP session can be migrated even if not all phases have been completed (e.g., LCP, PAP/CHAP completed but not IPCP and CCP). In such cases, the incomplete phases will be negotiated at the PPP of the Target PPP.

  • Patent number: 7693134
    Abstract: The invention comprises a method and apparatus for providing multimedia content to a calling party device. Specifically, the method comprises receiving a connection establishment request from a calling party device where the connection establishment request is operable for establishing a connection between the calling party device and a called party device in an Internet Protocol (IP) Multimedia Subsystem (IMS) network, obtaining multimedia content information in response to the connection establishment request where the multimedia content information is operable for establishing at least one multimedia session with the calling party device, and transmitting at least a portion of the multimedia content information towards the calling party device contemporaneously with establishment of the connection.

  • Publication number: 20050159181
    Abstract: A method and apparatus for interconnecting a wireless network and a wireline network include the division of processing functions between a main processor and a plurality of micro-engines. In accordance with an embodiment of the present invention, respective micro-engines perform the data flow processing of data packets for each of the stages of an interconnection pipeline process and a global main processor performs the control processing of data packets for the interconnection pipeline process.

  • Publication number: 20040131059
    Abstract: In illustrative embodiments, equivalent network processing of packets is performed at a single node instead of at a large number of special purpose nodes. A single-pass pipelined packet scan at the single node permits required actions to be taken in an integrated manner to avoid repetitive processing. Processing is conveniently accomplished in separate stateless and stateful segments, with state-related information derived during the stateless packet scan segment tagged to processed packets as required for subsequent stateful processing.
