Abstract: A wireless apparatus may receive scheduling definitions from a networking device. The wireless apparatus may determine, from the scheduling definitions, downlink transmission times and to start a timer at one of the determined downlink transmission times. The wireless apparatus may discontinue reception at expiration of the timer. The wireless apparatus may also, in response to reception of a downlink transmission, transmit an acknowledgement and to discontinue reception before the timer has expired.

Abstract: A wireless node in a wireless network may transmit information indicating a first reception schedule and a second reception schedule. The first reception schedule and the second reception schedule may be used by other wireless nodes to determine a sequence of time intervals for reception. Data may be transmitted to the other wireless nodes based on the scheduled transmissions.

Abstract: A method for operating a user communication device (18a, 18b, 19a, 19b), and a program and user communication device that operate in accordance with that method. An interface (2d, 2b, 23, 22) of the communication device (18a, 18b, 19a, 19b) is operated to enter identifiers identifying respective calling sources (18a, 18b, 19a, 19b) from which call signals may be received. The interface also is operated for entering into the device (18a, 18b, 19a, 19b) electrical signals representing corresponding audible signals that are to be individually generated in response to calls being received from the respective calling sources (18a, 18b, 19a, 19b). The identifiers are stored in a memory (2c, 24) in association with respective ones of the electrical signals.

Abstract: A wireless apparatus utilizes a wireless transceiver, in communication with a processor, to transmit and receive messages via a wireless network. The wireless transceiver may receive a schedule definition for devices affiliated with a node of the wireless network. The processor may determine, from the received schedule definition, one or more time periods allocated to the wireless apparatus. The wireless transceiver may communicate with the wireless network in accordance with at least one of the one or more time periods.

Abstract: A system for conserving energy in a multi-node network (110) includes nodes (205) configured to organize themselves into tiers (305, 310,315). The nodes (205) are further configured to produce a transmit/receive schedule at a first tier (310) in the network (110) and control the powering-on and powering-off of transmitters and receivers in nodes (205) in a tier adjacent (315) to the first tier (310) according to the transmit/receive schedule.

Abstract: Systems and methods are disclosed for controlling medium access. In one embodiment, the method includes receiving a first message including a first integer and a first sequence number; sending a second message including a second integer and the first sequence number; determining a first encryption key based on the first sequence number; and receiving a third message including a second sequence number and data, the second sequence number identifying a second encryption key capable of decoding the third message.

Abstract: A method for testing a speaker (212) and microphone (216) of a communication device (110) is provided. The method includes playing a first audio signal through the speaker (212) and determining whether the first audio signal is audible. If the first audio signal is audible, the communication device (110) receives a second audio signal through its microphone (216) and plays the second audio signal through the speaker (212). If the second audio signal is audible the method determines that the microphone (216) is properly functioning. Such a method allows the communication device (110) to be quickly and easily tested.

Abstract: The disclosed systems and methods provide for the compression and decompression of packet headers. An uncompressed header can be compressed in size to form a smaller, compressed header, such that the compressed header can include values that can be used to re-produce the uncompressed header. A compressed header can include at least two such values. A first value of the at least two values can be computed based on a second, earlier uncompressed header and can be used to derive the uncompressed header. Similarly, a second value of the at least two values can be computed based on a third uncompressed header and can be used to derive the same uncompressed header. Accordingly, the uncompressed header can be derived based on the first value and the second uncompressed header, or based on the second value and the third uncompressed header. The uncompressed header, second uncompressed header, and third uncompressed header can be associated with different packets.

Abstract: A system and method for transmitting information to a group of recipient devices according to a transmission schedule is provided. A sequence of M blocks of information are transformed into N transformed blocks, where M and N are integers and N?M. Each of the N transformed blocks are transmitted to a group of user devices in a network in accordance with a transmission schedule. At one of the user devices, at least some of the N transformed blocks are received. When K distinct transformed blocks have been received, where K is an integer and K<N, the information is reconstructed from the K transformed blocks. In some implementations, at least one recipient device reduces power, after receiving a recipient schedule including a transmission time of at least one desired content, until or near the transmission time of the at least one desired content.

The radio units (130) are associated with radio channels. Combinations of the interface units (120) and the radio units (130) provide conversion of constant bit rate communication to packetized communication and reconversion of the packetized communication to the constant bit rate communication.

Abstract: The present invention performs “flow control” based on the remaining encryption capacity of an encrypted outbound network interface link of a network routing device, such as a router or switch. As the encrypted link begins to run low on encryption key material, this invention begins to discard datagrams queued for transit across that link, in order to signal distant host computers that they should slow down the rate at which they are sending datagrams. The invention, which is particularly useful in cryptographically protected networks that run the TCP/IP protocol stack, allows fine-grained flow control of individual traffic classes because it can determine, for example, how various classes of data traffic (e.g., voice, video, TCP) should be ordered and transmitted through a network. Thus, the invention can be used to implement sophisticated flow control rules so as to give preferential treatment to certain people, departments or computers.

Abstract: A system stores pedigrees that include details of how and when each of multiple blocks of encryption key material were distributed between two endpoints using quantum cryptographic techniques. The system receives an indication of a possible quantum cryptographic security violation and accesses the stored pedigrees to identify one or more of the multiple blocks of encryption key material that may have been compromised.

Abstract: A system and method for adding a new network device to an existing network is described. An existing network has at least one master network device that acts as the gatekeeper for adding new network devices to the network. The master network device receives a request from a new network device to join the network. In response, the master network device issues a request to the new network device to perform a specified action. The master network device receives verification from the human user that the specified action has been performed. Upon receiving the verification, the master network device adds the new network device to the network.
