Radio channel metrics for secure wireless network pairing
Technologies are generally described for using metrics of radio path characteristics within a wireless network to establish signal signature vectors. These signal signature vectors may be used as a shared secret between network nodes to establish affirmative identification. For example, a signal signature vector may be established when a new node sends a fixed number of packets to the existing nodes and the existing nodes send a fixed number of other packets back to the new node. The number of properly received packets can be counted to establish a success probability between the new node and each existing node. These probabilities can be normalized and quantized to generate signal signature vectors at each node. Without every transmitting any of the vectors, the vector at the new node should be highly correlated to the vectors at existing nodes since the pair-wise channels between each of the nodes should be reasonably symmetrical.

Method for identifying peptides using tandem mass spectra by dynamically determining the number of peptide reconstructions required
A method for identifying peptides using tandem mass spectrometry takes the spectrum for a peptide to be analyzed and uses a scoring function to score a match between the spectrum and each candidate peptide in a peptide database. The scoring function has a value corresponding to a number of fragment peaks in the spectrum that match fragment peaks in a spectrum of the candidate peptide. Using the match scores, a generating function of the spectrum is computed to determine the number of peptide reconstructions at each value of the scoring function. The generating function is then used to determine the number of candidate peptides for each match score and the probability of a peptide having a given match score to the spectrum. A spectral probability can be determined by calculating the total probability of all peptides with scores equal to or larger than the given match score.

A switching logic may be configured to map the source subchannels to the destination subchannels as virtual channels to forward the packets from the source subchannels to the destination subchannels. A single queue may be configured to couple with the switching logic to record packets from the source subchannels into a packet stream for a delay period to distribute to the destination subchannels. The destination logic may emulate the source logic synchronized with the plurality of clock domains delayed by the delay period.
Heterogeneous forwarding information bases in line cards
A device may include a control module configured to distribute sets of routing entries to line cards, each of the sets including a portion of a master table for looking up routes based on network addresses. In addition, the device may include a first one of the line cards configured to receive one of the sets of routing entries, store the received set of routing entries in a local table, receive a packet from a network, obtain a routing entry using the local table based on an address associated with the packet, and send the obtained packet to a second one of the line cards, the second line card associated with the routing entry. Further, the device may include the second line card configured to forward the packet toward the address in the network.
Multicast hello on demand
In one embodiment, a particular multicast-enabled device on a LAN may determine that it is to send a Join message to an upstream multicast-enabled device that is configured to source multicast data into the LAN. As such, the particular device may transmit a Join message to the upstream device, where the Join message may have a Hello Request indication when there are no downstream multicast neighbors for the upstream device in the LAN, or may not have the Hello Request indication if there is at least one downstream multicast neighbor for the upstream device. Specifically, the Hello Request requests that the upstream device transmit Hello messages onto the LAN. Multicast-enabled devices in the LAN may thus transmit Hello messages in response to receiving a Join message having a Hello Request directed to that particular device, that is, transmitting the Hello messages so long as there is interest in receiving them.
Methods and apparatus for managing voice over IP telephony
Methods and apparatus are provided for: obtaining information at an administrative entity concerning one or more voice-over-Internet (VOI) calls gathered at one or more session controllers operatively coupled between one or more packet switched networks and one or more public switched telephone networks; analyzing the information to determine whether any of the calls are inactive; and sending at least one command from the administrative entity to the one or more session controllers that causes the session controllers to drop any VOIP calls that are determined to be inactive.
Method and system for sleep mode signaling for a multi-standard system with bluetooth
Aspects of a method and system for sleep mode signaling for a multi-standard system with Bluetooth are provided. In this regard, a first communication system that communicates utilizing TDM may generate a synchronization signal that is communicatively coupled to a second communication system that communicates utilizing TDM. The first communication system may determine one or more timeslots during which it may be inactive. The first communication system may control, based on the determination, an amount of time that the synchronization signal is in one or more states. The second communication system may receive the synchronization signal from the first communication system. The second communication system may determine timeslots during which the first communication system may be inactive based on an amount of time that the synchronization signal is in one or more states. The second communication system may transmit and/or receive at times that are scheduled based on the determination.
Method and apparatus for reporting WLAN capabilities of a dual mode GPRS/WLAN or UMTS/WLAN WTRU
Method and apparatus for enabling a wireless terminal to communicate the dual-mode capabilities and reporting the interworking capabilities of the two networks with which the wireless terminal have the added capability of obtaining services from either one of the interworking networks.
Signal encoding method and device, method for encoding joint feedback signal
A signal encoding method and device and a method for encoding a joint feedback signal are provided. The signal encoding method includes the following steps. When two carriers are configured with multiple-input and multiple-output (MIMO), Hybrid Automatic Repeat reQuest-ACKnowledgement (HARQ-ACK) signals of the two carriers are combined into a joint feedback signal. The joint feedback signal is mapped into a codeword according to predetermined mapping relationship between signals and codewords. Therefore, through the method for combining and encoding feedback signals of two carriers for transmission on a code channel in a dual cell (DC)-MIMO mode, bit error ratio (BER) and detection error cost are decreased, power overhead is saved, and a cubic metric (CM) value of the system is not affected, thereby enhancing the performance of the system.
