  • Patent number: 7742490
    Abstract: 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.

  • Publication number: 20090255000
    Abstract: An extension to the Location Information Service (LIS) architecture uses a centralized, user-selected, Privacy Profile Register (PPR) and Presence Register (PR) element, the User Privacy and Presence Register (UPPR) (also known as the Home Register (HR)). This centralized model provides access to value added services that allow the user to be located anywhere in the world by people and services of his choosing. It also provides network elements using this location information with security that the location being provided has certification.

  • Patent number: 6636508
    Abstract: A communications network resource conservation system is provided for that conserves network bandwidth and improves voice quality. The method and apparatus permit users of H.323 terminal devices to talk to each other directly over the Internet thereby eliminating the need to use the resources of a telephone switch and a Public Switched Telephone Network (PSTN). Communication between users is established directly via packet network. In one embodiment, a voice path between users is directly established without routing the voice through a PSTN as for a typical telephone call and yet get supplementary services from the PSTN switch. The telephone call will be set up through the telephone switch and the PSTN as for a normal call, but, the voice path will be Intraswitched directly between the calling party and the called party via their packet network.

  • Publication number: 20030126299
    Abstract: In a hierarchical tree-based protection scheme, a node in a mesh network is designated as a root node of a spanning hierarchical protection tree and subsequently invites each adjacent node to become its child within the tree. If the inviting node provides a more capacious protection path to the root node than is currently enjoyed by the invitee, the invitee designates the inviting node as its primary parent and assumes a new tree position. Otherwise, the invitee designates the inviting node as a backup parent. A node assuming a new tree position invites all adjacent nodes except its parent to become its child. The invitations propagate throughout the network until a spanning hierarchical protection tree is formed. Upon a subsequent failure of a straddling link, the tree may be used to re-route data. Further, given a tree link failure, protection switching is quickly achieved at a disconnected node through use of a backup parent as the new primary parent.
