Patent number: 7266092Abstract: A communication system and method adaptively control frequency ranges of a pair of interconnected transceivers in an effort to enhance the data rate in one direction. In this regard, a full duplex communication session is established between a first transceiver and a second transceiver. Signals having frequencies within an overlapping bandwidth are communicated between the first and second transceivers during a data phase. A transmission capacity of one of the transceivers is determined based on the communicated signals, and a comparison between this transmission capacity and a specified transmission capacity for the one transceiver is performed. A portion of the overlapping bandwidth is adaptively selected based on the comparison, and the one transceiver is prevented from transmitting signals having frequencies within the selected portion of the bandwidth during the data phase.Type: GrantFiled: January 30, 2003Date of Patent: September 4, 2007Assignee: Adtran, Inc.Inventors: Kevin W. Schneider, Arlynn W. Wilson

Patent number: 7263068Abstract: Apparatus for determining a protocol of messages traversing a signalling link in a telecommunications network includes a memory for storing one or more predetermined characteristic of a message in the protocol that can be used to distinguish that protocol from other protocols. A protocol auto-discovery module is coupled to the memory and to a module that extracts channels from signalling link timeslots. The protocol auto-discovery module determines whether the predetermined characteristic is present in the sampled message and identifies the signalling link as carrying messages in the particular protocol if the predetermined characteristic is present in the sampled message. The identification may be based on a confidence measure stored in a channel configuration table which is incremented when a message on the signalling link is identified as being in that particular protocol and decremented when a message is identified as being in another protocol.Type: GrantFiled: July 23, 2003Date of Patent: August 28, 2007Assignee: Agilent Technologies, Inc.Inventors: Michael Hurst, Kate Patterson, Craig Renfrew

Patent number: 7236471Abstract: The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.Type: GrantFiled: February 18, 2004Date of Patent: June 26, 2007Assignee: Autocell Laboratories IncInventors: Floyd Backes, Gary Vacon, Paul Callahan, William Hawe

Patent number: 7224668Abstract: An internetworking device that provides improved immunity to Denial of Service attacks, and in general, improved Quality of Service (QoS). An internetworking element or other route processor is composed of two main parts, including a data forwarding plane and a control plane; the control plane runs routing, signaling and control protocols that are responsible for determining the packet forwarding behavior by the data plane. Independent control plane processes may be provided; however, they are considered to be a single network entity that is a uniquely addressable port. Packets thus intended for the control plane always pass through a designated point. As a result, a set of port services unique to the control plane may be applied to the control plane port. These control plane port services thus can be utilized to control all packet traffic entering and exiting the control plane processes as a whole.Type: GrantFiled: November 27, 2002Date of Patent: May 29, 2007Assignee: Cisco Technology, Inc.Inventors: Adrian C. Smethurst, Michael F. Keohane, R. Wayne Ogozaly

Patent number: 7221664Abstract: A communication system, such as a wireless CDMA system, detects markers with fewer errors by having field units transmit the markers at different power levels (e.g., 9 dB for one marker and 11 dB for another marker). The difference in power levels of the markers allows the base station to identify the request markers using alternative criteria with a low probability of error, where the alternative criteria may include comparing the markers to respective energy level thresholds, monitoring occupancy of time slots, occupancy of mutually exclusive code channels, or combinations thereof. For example, in one particular embodiment, a request marker, which is generally a high priority marker, is transmitted with higher power, which improves the probability of detection and reduces the probability of false detection of the request marker.Type: GrantFiled: June 12, 2002Date of Patent: May 22, 2007Assignee: InterDigital Technology CorporationInventor: James A. Proctor, Jr.

Patent number: 7218636Abstract: A method for providing an early packet termination such that prior to the complete transmission of the number of cells specified in the first cell of a packet, a crossbar connection is released. The act of releasing the connection is triggered on recognition of an End of Packet bit (EOP) set in any cell of the stream. The feature can be enabled, for example, by a specific act of setting a register bit, connecting a pin to Vcc or ground or some other intentional act. The feature will default to the inactive state upon reset.Type: GrantFiled: November 29, 2001Date of Patent: May 15, 2007Assignee: Inrange Technology CorporationInventors: Harry V. Paul, Richard Branco, Jereld W. Pearson, Gregory L. Koellner

Patent number: 7203198Abstract: One embodiment of a method for switching ATM cells using Early Packet Discard and Partial Packet Discard is provided. Initially, a first cell of an AAL5 packet is received at an input port. Next, it is determined whether there is likely to be enough buffering available to handle the whole packet (i.e., up to 64 Kbytes). If it is determined that sufficient buffering is unlikely to be available, the entire packet is discarded. If it is determined that sufficient buffering exists, the cell is received and buffered for subsequent transmission. Next it is determined whether the flow's buffer is filled at any time after initial transmission of a AAL5 cell but before reception of the final cell. If such a state is determined, the current cell is discarded and a flag is set in the flow structure so that subsequent cells of the same packet, except the last, will also be discarded.Type: GrantFiled: April 17, 2002Date of Patent: April 10, 2007Assignee: Conexant, Inc.Inventors: Brian James Knight, Timothy John Chick

Patent number: 7180905Abstract: An access method for periodic contention-free sessions (PCFS) reduces interference between overlapping first and second wireless LAN cells contending for the same medium. Each cell includes a respective plurality of member stations and an access point (AP) station. The access method for periodic contention-free sessions (PCFS) includes a fixed cycle time that reduces conflicts with PCFS from other cells. The PCFS from several cells are repeated in cycles of cycle period (CP), which is the contention-free period (CFP) of an access point times a factor that is a function of the number of overlapping cells. Periodic contention-free sessions (PCFSs) are generated, one from each overlapping cell. PCFS transmission attempts occur at the fixed specified time spacing following the start of the previous cycle. Each active AP sets a timer at CP and a PCFS is initiated when the timer expires. The timer is then reset to CP and this starts a new cycle.Type: GrantFiled: September 27, 2002Date of Patent: February 20, 2007Assignee: AT & T Corp.Inventor: Mathilde Benveniste
