Abstract: An advanced gateway for multiple broadband access can include a plurality of broadband network interfaces. The advanced gateway can route data from a local network interface to a broadband network interface when a performance attribute of the broadband network meets or exceeds a data characteristic of data conveyed through the local network interface. In another embodiment, a first advanced gateway can send a portion of data received through the local network interface to a second advanced gateway when performance attributes associated with the first advanced gateway cannot meet or exceed a data characteristic of data received through a local network interface of the first advanced gateway. In yet another embodiment, an advanced gateway can receive commands from service providers, determine a recipient device for the command and forward the command to the recipient device through a device interface coupled to the recipient device.

Abstract: Protocol data units (PDUs) associated with a packet stream are transmitted with sequence numbers to support reordering and selective acknowledgement. A selective acknowledgement (SACK) message may be used to indicate at least one sequence number of a lost or corrupted PDU which was not properly received by the receiving device. Responsive to the SACK message, the lost or corrupted PDU is retransmitted via a different path of the network, different from the path used to transmit the original PDU. Lost or corrupted PDUs may not be retransmitted if the estimated retransmission delay is greater than a delay tolerance associated with the quality of service requirements of the application. Instead, a control message (i.e. “cut losses” message) may be transmitted to indicate that PDUs earlier than a particular sequence number will not be transmitted.

Abstract: A system for providing architecture and signaling, by which a mobile communications device—active within a WLAN environment—may be effectively and efficiently interfaced with a CDMA2000 network to provide cooperative and concurrent VoIP and over-the-air (OTA) communications, is disclosed. A wireless communications system comprises a mobile station, operating in a wireless LAN environment. The mobile station access the Internet through a wireless LAN access point. The area is also provided service by a CDMA2000-based over-the-air network. A provisioning server, within the CDMA2000-based network, is accessible via the Internet. A mobile switching center is also within the CDMA2000-based network. An interface construct is communicatively coupled to the mobile switching center and to the wireless LAN, and is adapted to facilitate call traffic between the CDMA2000 network and the mobile station over the wireless LAN.

Abstract: Rate adaptation in network communications can be determined, at least in part, by bit error rates through network communication channels. Bit error rates can provide an indication of channel conditions and can guide selection of data rate settings by network devices. Relatively good channel conditions can support relatively higher data rates while communication channels with relatively more noise and/or interference can support relatively lower data rates. Transmitted data can be coded with Forward Error Correction codes that can allow determination of bit error rates resulting from transmission. In one embodiment, bit error rates can guide carrier selection when data is transmitted with groups of two or more carriers such as with orthogonal frequency division multiplexing modulation.

Abstract: Systems, methods and computer-readable media proportionally schedule packet transmission on a network. A node maintains a plurality of buffers configured to store packets to be transmitted by the node on a network. Each of the buffers may have a buffer priority and a buffer length. The node receives one or more channel access parameters. The channel access parameters may be determined in accordance with a link quality between the transmitting node and one or more receiving nodes. The node selects packet to be transmitted from a buffer based on the channel access parameters, the buffer priority of the buffer, the buffer length of the buffer and a deprivation factor associated with the packet.

Abstract: A base station for use in a 1xEV-DV/DO wireless network that communicates with mobile stations in its coverage area. The base station comprises a handoff controller for receiving a Handoff Request message from a first mobile station attempting to hand off to the base station.

If the available resources exceed the predetermined minimum threshold, the handoff controller allows the first mobile station to be handed off to the base station. Otherwise, the handoff controller prevents the first mobile station from being handed off to the base station.
