  • Authorizing communication services
    Patent number: 7571238
    Abstract: The present invention provides for a communication server of a service provider to authorize resource reservation for a communication over a packet-switched network without requiring the communication server to know the identity of or significant details about the network elements providing the communication. The communication server is configured to provide secure authorization indicia to the terminal receiving or delivering information for the communication. The terminal presents the authorization indicia to one or more network elements involved in reserving resources for the communication. The network element or elements will use the authorization indicia to authorize resource reservation for the communication, and may forward the authentication to additional network elements involved in reserving resources for the communication.
