System and method for finding a picture image in an image collection using localized two-dimensional visual fingerprints
An image management method and system provides for storing, indexing, searching and/or retrieving image data. The content of an image collection is pre-processed to identify stable and repeatable keypoints for each image in the collection. Fingerprint information is computed from local groups of keypoints, and the resulting fingerprint information is stored in a compact fingerprint database.

Method and apparatus for single burst equalization of single carrier signals in broadband wireless access systems
A receiver implementing a single carrier single burst equalization (SC-SBE) method is capable of achieving near optimal reception of individual single carrier RF bursts by making an accurate estimate of the burst's propagation channel impulse response (CIR).

The resulting FFF and FBF are sparse filters in that most of the taps in the filter delay lines do not have a filter coefficient. Such filters may be efficiently implemented in the time domain. |

IP communication apparatus and IP communication method of such apparatus
An IP terminal apparatus has a SIP controller, a UDP packet controller, and an RTP controller. The SIP controller transmits and receives a call control message in order to establish a connection to and from a destination apparatus. The UDP packet controller transmits and receives media data with the destination apparatus in a media session after the connection was established. The RTP controller obtains source port number information of a media data packet that the UDP packet controller has received from the destination apparatus, and sets the obtained source port number as a destination port number for a packet to be transmitted to the destination apparatus. Thereby, a feasible range of NAT traversal can be improved in a simple and secure manner, even when at least one relay apparatuses employs symmetric NAT. |

Method to reduce the transmission latency in GSM/EDGE delay-sensitive applications
A transmitting peer transmits radio blocks over a radio interface from within a transmit window. A receiving peer receives the radio blocks within a receive window, and in case of a not correctly received radio block, sending back a NACK (Not Acknowledged) signaling message to inform the transmitting peer of reception failure. Upon reception of the NACK signaling message, the transmitting peer retransmits, until expiration of the transmit window, the not correctly received RLC/MAC radio block. The radio blocks are re-assembling in sequence at the receiving peer. Each radio block is considered as being permanently lost if not correctly received within the receive window. All correctly received radio blocks are delivered to a higher protocol layer. The network transmits a notification message to both the transmitting peer and the receiving peer to select a size of the transmit and receive windows inside a range of predetermined values including values less than 64 radio blocks. |

Scalable data forwarding techniques in a switched network
Scalable data forwarding techniques in a switched network are described herein. In one embodiment, an example of a process for forwarding data includes, in response to a first packet received from a first local node over a local area network (LAN) and destined to a first remote node over a provider network, a provider edge (PE) device of the provider network substituting a source MAC (media access control) address of the first packet with a virtual MAC address associated with the PE device, and the PE device transmitting the first packet having the virtual MAC address as the source MAC address to the first remote node over the provider network. Other methods and apparatuses are also described. |

System and method for discovering SCTP associations in a network
Systems and methods for discovering SCTP associations between devices communicating in a network are described. A method comprises monitoring packets communicated among a plurality of source and destination devices, determining a combination of source EP address, source port number, destination IP address, and destination port number that defines an association between a source device and a destination device, and resolving a combination of source and destination verification tags that further defines the association based upon the combination of EP addresses and port numbers. The method further comprises ascertaining whether a subsequently monitored packet belongs to the association based at least in part upon an element of the combination of verification tags after at least one element of the combination of EP addresses and port numbers has changed during the ongoing communication. |

Method, apparatus and system for establishing a direct route between agents of a sender node and a receiver node
In the present technique of a communication system (100), an address of a forwarding agent (114) linked to a receiver node (112) is detected to provide a discovered address. The discovered address is then used to establish a direct route with the forwarding agent of the receiver node for subsequent communications between a sender node (104) and the receiver node. |
