  • Method for allocating network resources
    Patent number: 7492886
    Abstract: Network resources for a call between a calling party and a called party are allocated. The network resources for the call are reserved based on a reservation request. In particular, the network resources for the call are reserved based on a reservation request. Prior to the reservation request being made, one or more operational parameters for the call are established by a gate controller and sent to a network edge device or other routing entity associated with one of the parties. An identifier, illustratively a so-called gate identification, is sent to that party. Thereafter the routing entity receives the identifier from the associated party in, for example, the aforementioned resource reservation request. The routing entity is able to use the identifier to determine the one or more parameters established for the call and to thereupon cause the call to be established—including the reserving of resources—in a way that is consistent with the one or more parameters.
