  • Publication number: 20050030889
    Abstract: A method for transmitting call processing-related traffic in a voice over packet network having a plurality of bearer links. The method includes creating at least one logical tunnel in each of the bearer links, establishing a priority for the call processing-related traffic, and transmitting the call processing-related traffic through the logical tunnels in the bearer links.

  • Publication number: 20040264455
    Abstract: A method and apparatus for processing calls in a core packet network using a half-call model are provided. The invention is directed to the processing of calls within the core packet network of a mobile switching center (MSC) by dividing the call into two half-calls—an originating half-call and a terminating half-call. This technique allows for flexibility in implementation.

  • Publication number: 20040240389
    Abstract: A method and apparatus for load balancing and overload control of packet media gateways under control of a single media gateway controller is provided. More particularly, the invention is directed to a technique for load balancing and overload control by defining an interface between the media gateway (MG) and the media gateway controller (MGC) to handle both load balancing as well as general congestion and resource congestion. In addition, a new event strategy is defined that reports resource utilization so that the media gateway controller (MGC) can take appropriate action to maximize call completion. Such action may include evenly distributing traffic among available media gateways, smart routing around a congested media gateway or intelligent throttling of traffic based on knowledge of specific resources that are congested.
