  • Publication number: 20150003240
    Abstract: A method of adaptively routing voice packets in an IP network receiving a request for a new call at a voice gateway, determining a destination gateway for the new call, determining an availability of at least one route for routing the new call across the IP network to the destination gateway, and deciding whether to admit the new call into the IP network based on whether a route is available over which voice packets for the new call can be routed. A call admission decision is made based on whether a direct, single-path route or a two-path route is available, where each path is an LSP tunnel whose availability is determined using a token bucket technique. If no route is available, the voice gateway does not admit the call into the IP network.

  • Patent number: 8385197
    Abstract: A communication system is provided that can control which communication sessions with mobile devices are admitted to a wireless access point. The admission decisions are based on actual measurements of radio frequency (RF) utilization. The RF utilization is determined on a per access class basis. Access classes may be defined by protocol but are, generally, voice, video and data. Thus, the system provides the ability to determine admissions that allows for the incorporation of factors including collisions, the distance from the access point to which a mobile device is communicating, and other factors.
