Abstract: One embodiment includes distributing user traffic packets to a plurality of queues, and draining the queues of the user traffic packets according to a defined methodology. The drained user traffic packets are sent to a plurality of physical channel interfaces. Each of the plurality of physical channel interfaces interfaces with a respective channel of the backhaul. The sending step sends each of the drained user traffic packets to the physical channel.

Abstract: A permanent virtual circuit (PVC) over an ATM network is provisioned by using a deterministic PVC addressing scheme for computing a unique combination of VPI and VCI values based on certain input parameters associated with the network to which the PVC is logically connected. Specifically, the VPI and VCI of a PVC are deterministically computed as a known function of numerical values of particular network elements associated with the network and the particular PVC being provisioned using a function that enables the values of these network elements to be uniquely determined from the VPI and VCI of the PVC. Thus, once the VPI and VCI are determined for a PVC, the particular network elements associated with that PVC can be unambiguously identified from their values.

Abstract: The method provides power control in transmitting a downlink signal of frame data in a wireless network. Each frame is composed of timeslots, with each timeslot being further composed of quarter symbols. The method includes mapping each quarter symbol to an offset within a frame attenuation buffer, and computing a template for the frame, each step being performed only once. The template is used for filling the attenuation buffer with attenuation values to attenuate the transmit power for the downlink signal. Attenuation values are provided for each quarter symbol in a frame, although a computation is not required for each quarter symbol. The attenuation values are grouped in blocks that are recursively copied into the frame attenuation buffer based on the template. The contents of a filled attenuation buffer are output for use in attenuating the transmit power of the frame.

Abstract: Software defined radios necessitate the routing of analog wireless signals between data links via a software circuit switching router implemented in a processor. Processor utilization by the software router is decreased by disabling the interrupts of all but one analog channel per communication link, this channel being termed the Anchor channel for its link. Data from all channels in the link is transferred during the Anchor link's interrupt. The increase in the Anchor channel's interrupt latency due to transferring data from other channels is more than offset by the overall reduction in the number of processor interrupts generated. As a result, utilization of the processor by the software router is reduced, allowing the processor to manage other time-critical tasks and/or a greater number of tasks in a given time period.
