Abstract: There is provided a sensor network information collection mechanism in which, after a UE has decided to become part of an information collecting operation for collecting information from a local sensor network, a signaling transmitted from a managing node of a local sensor network is received and processed. A communication network control element is informed about the willingness to become an information collector by sending a report message comprising measurement results derived from the signaling received from the managing node of the local sensor network. When receiving a gateway allocation message indicating that the UE is determined to be a gateway element to the local sensor network, the information collecting operation is started wherein sensor nodes of the local sensor network are woke up, and a traffic flow direction in the local sensor network is set in accordance with the managing node identity to which the UE is accessed.

Abstract: A method and system of reducing/eliminating ripple in an electric motor. An electric parameter, such as current is sensed in an input electric signal. Ripple is detected in the signal using one or more current sensors and a discrete Fourier transform calculation. Ripple is reduced by adjusting the electric signal being sent from a drive control to an electric motor, using a closed-loop configuration. The electric motor might be a regenerative electric motor that is configured to sink or supply electricity to a power grid.

The method includes a user equipment receiving broadcasted wireless sensor network information; requesting access information for the wireless sensor network from a base station of a mobile data network; receiving the access information from the base station; and accessing the wireless sensor network using said access information.

Abstract: A mobile gateway device collects identities of a first set of radio nodes which are within one hop of the mobile gateway; and checks at least the collected identities against a first table and a second table. The first table lists node identities and corresponding data validity timers. The second table lists node identities and no corresponding data validity timers. From the checking the device selects a group of radio nodes to activate for collecting and reporting data. The device determines parent child relations among the radio nodes, which are sensor nodes of a wireless sensing network in an embodiment, and uses the list to activate only those nodes for which it does not have valid data to sense new data and transmit their sensing results.

Abstract: From a plurality of messages provided by at least a first license-exempt access node which give usage information for the at least one channel in license-exempt radio spectrum, there is derived channel-specific statistical traffic information. This information for the channel is then provided to a second access node that controls licensed radio spectrum. Or in another embodiment the second access node can get this information by sensing and measuring the channel itself. The second access node retrieves this information from its local memory and sends on the licensed radio spectrum a downlink message having contents, determined from the channel-specific statistical traffic information, for aiding a user equipment UE to access the channel with a probability defined by the contents. The UE receives this message, extracts the contents, and attempts to access that channel in the license-exempt radio spectrum utilizing the defined probability.

Abstract: A method and an apparatus for switching D2D data communications between a licensed and a license-exempt band are disclosed. A D2D device receives from a cellular network a pre-switch notification to prepare for a switch of its D2D communications, and in response adopts a temporary strategy for conducting its D2D transmissions prior to the switch. After the switch the D2D device discontinues the temporary strategy. In one embodiment the temporary strategy and its duration are indicated in the pre-switch notification. Two example temporary strategies are presented: ‘no-new-data’ where new data transmissions are suspended and data re-transmissions are sent with high reliability; and ‘no-feedback’ where new data is sent with high reliability and data re-transmissions are suspended. Different embodiments have the cellular network access node or D2D device contending for the radio resource in the license-exempt frequency band.
