  • Patent number: 7068598
    Abstract: An IP Packet Access Gateway (IP PAG) system manages an IP bearer path between communicating IP endpoints. The system includes an IP PAG having a first IP bearer connection termination for terminating a first bearer connection with a first IP endpoint, and a second IP connection termination or terminating a second bearer connection with a second IP endpoint. A call control entity is associated with the IP PAG and communicates call control instructions thereto. The call control instructions include instructions for logically concatenating the connections into an active IP bearer path extending between the first IP endpoint and the second IP endpoint. A bearer traffic IP packet handler in the IP PAG moves bearer traffic IP packet payloads over the active IP bearer path.

  • Patent number: 6925082
    Abstract: An ATM Packet Access Gateway (ATM PAG) system manages an ATM bearer path extending between ATM endpoints participating, for example, in a VoATM call. The system includes an ATM PAG having a first ATM bearer connection termination for terminating a first bearer connection with a first ATM endpoint, and a second ATM connection termination for terminating a second bearer connection with a second ATM endpoint. A call control entity is associated with the ATM PAG and communicates call control instructions thereto. The call control instructions include instructions for logically concatenating the first and second ATM bearer connections into an active ATM bearer path extending between the first ATM endpoint and the second ATM endpoint. A Media Access Gateway (MAG) function of the ATM PAG is responsible for establishing the connections that form the ATM bearer path. An ATM switch function of the ATM PAG moves bearer traffic ATM packet payloads over the active ATM bearer path.

  • Patent number: 6693898
    Abstract: A packet-based inteligent telecommunications network that adheres to a call control model currently used for circuit-switched intelligent networks. Messages defined in the GR-1129 specification are exchanged between a service switching point and service node intelligent peripheral within the facility information element of H.225 commands on a H.323 network.

  • Patent number: 6360107
    Abstract: An apparatus, method and system are provided for topological channel assignment for focused beam, fixed wireless telecommunications. The preferred system embodiment includes a plurality of transceivers coupled to a telecommunications switch, in which each transceiver utilizes a narrow focused beam on the order of ten degrees, for full duplex communication with fixed customer premise equipment. The geographic region is topologically divided, preferably, into a plurality of adjacent cells, in which each adjacent cell utilizes a distinctive, orthogonal code set from a 10 MHz spectrum. As channels, the various code assignments may be dynamically determined at any given time. The switch includes instructions for determining the cell configurations, determining an available channel (code) set for a selected cell, and within the selected cell, determining the plurality of focused beam ranges to create a corresponding plurality of sectors.
