ZIGBEE SYSTEM MANAGEMENT EMPLOYING A TR-069 ENABLED CPE PROXY
A ZigBee management system includes an auto configuration server (ACS) that manages customer premises equipment (CPE) through CWMP messaging and a CPE proxy that is coupled to the ACS to provide a protocol translation between the CWMP messaging and ZigBee device object (ZDO) messaging for a ZigBee device. The ZigBee management system also includes a hybrid ZigBee coordinator that is coupled to the CPE proxy and has a ZigBee protocol stack having a ZigBee MAC layer as an initial layer, a non-ZigBee physical layer that is coupled to the ZigBee protocol stack and communicates the ZDO messaging over a non-standard ZigBee interface with the CPE proxy, and a ZigBee physical layer that is coupled to the ZigBee protocol stack and the non-ZigBee physical layer and transceives the ZDO messaging for the ZigBee device over a standard ZigBee interface. A method of managing a ZigBee network is also provided.
Star topology fixed wireless access network with lower frequency failover
A fixed wireless access network provides for high-frequency data links between aggregation nodes and endpoint nodes. The system further provides for lower frequency wireless data links, which have carrier frequencies less than high-frequency wireless data links. These lower frequency links provide for auxiliary communications between the aggregation nodes and one or more endpoint nodes. During normal operation, the nodes exchange packet data via the high-frequency data links. However, when impairment of the high-frequency data links is detected, the nodes direct the packet data over the low-frequency data links instead until the high-frequency data links are no longer impaired.

ANOMALY HANDLING METHOD AND ANOMALY HANDLING DEVICE
An anomaly handling method in an in-vehicle network includes: transmitting and receiving frames; detecting a frame having an anomaly; and switching, when the anomaly is detected in the detecting, a transmission timing of the frame in which the anomaly is detected. The switching includes changing a switched transmission timing to which the transmission timing is switched, according to predetermined information.

METHOD AND SYSTEM FOR SHARING CONTENT
The present disclosure relates to methods and systems for sharing content, the method comprising receiving at a creator node, a selection of a first set comprising a plurality of joinee nodes, wherein each of said plurality of joinee nodes are associated with a corresponding unique identifier. The process further includes encoding the identifier associated with each of the plurality of joinee nodes in the selected first set and then transmitting the encoded identifiers to at least each of the plurality of joinee nodes in the first set. Next, the process includes receiving an acknowledgement from a subset of the first set, said subset comprising at least two joinee nodes, wherein said acknowledgement indicates a successful connection between the creator node and at least two joinee nodes in the subset. Subsequently, the method creates a network comprising the creator node and said subset and content is shared from the creator node to the subset via the created network.
