Abstract: Systems and methods are described for providing wireless backhaul transport. One element of the system is a highly integrated radio transceiver, including an integrated antenna. The radio transceiver may operate in the millimeter wave range (between 30 GHz and 300 GHz), and due to the small wavelengths, it is possible to integrate the antenna, which may typically compromise a number of antenna elements, with the radio transceiver in a single integrated circuit (IC) package, commonly referred to as a system-in-package (SiP) and/or antenna-in-package (AiP) format. The system supports multi-hop point-to-multipoint or multi-hop mesh networking topologies. Low level MAC routing tables are built and maintained to enable efficient packet and frame forwarding.

Abstract: A paging channel is monitored at a special position of every predetermined time interval subsequent to the last monitored time. It is detected whether a same first identity information is repeatedly broadcasted in the paging channel at special positions of different predetermined time interval. A total number of periodically repeated messages containing the same first identity information is determined. A new time interval is determined by multiplying a time period between two successive repeated paging messages with the total number of periodically repeated paging messages, wherein the new time interval has a monitoring interval (having a plurality of predetermined time intervals) equaling to the length of the time period and a sleep interval. The paging channel is monitored at special positions of the plurality of predetermined time intervals in every new time interval subsequent to the last monitored time so as to receive subsequent paging messages from the cell.

Abstract: A method, system, and/or computer program product improve Voice over Internet Protocol (VoIP) call quality during a VoIP session. A VoIP session is established between an initial focus VoIP node and multiple slave VoIP nodes, where the initial focus VoIP node uses a first type of codec for the VoIP session. A user focus code score (UFCS) describes a VoIP call quality for each of the nodes based on predetermined network conditions related to use of a certain type of codec and nodal hardware specifications. The UFCSs are ranked to identify a highest-ranked VoIP node. The highest-ranked VoIP node is reclassified as a new focus VoIP node for the VoIP session, and the initial focus VoIP node is reclassified as a slave VoIP node. Thereafter, there is a simultaneous switching of 1) the focus and 2) the type of codec used in the VoIP session.

Abstract: In one embodiment, a parent node in a network observes time slot usage of a channel hopping schedule by one or more child nodes of the parent node to communicate with the parent node. The parent node also identifies high priority traffic from a particular child node. The parent node detects time contention for the high priority traffic based on an indication that at least a portion of the traffic has been rerouted by a particular child node to a different parent node. In response to detecting the time contention, the parent node adjusts a communication strategy used by the one or more child nodes.

The message is sent from the first computer to the intermediate computer after which the destination address and the unique identity are used to find an address to the second computer. The current destination address is substituted with the found address to the second computer, and the unique identity is substituted with another unique identity. Then the message is forwarded to the second computer.

Abstract: A collision detection unit detects whether a first entry that is associated with a value obtained by hashing a first MAC address is present in each area in a MAC address table and detects whether a second entry that is associated with a value obtained by hashing a second MAC address is present in each area in the MAC address table. If the first entry is present in each of the areas, a collision avoidance control unit acquires the second MAC address stored in the first entry that is present in one of the areas and inputs the second MAC address in the collision detection unit. If the second entry is not present in any of the areas in the MAC address table, a registration unit stores the second MAC address in the second entry and stores the first MAC address in the first entry.
