20130072106 | Efficient Enablement For Wireless Communication On License-Exempt Bands - A fixed or Mode II device enables a Mode I device for license exempt operation by providing to it a list of available license exempt radio channels and a parameter indicating an interval at which contact verification signals CVSs are to be sent. The CVSs verify whether the list remains valid. The fixed/Mode II device then repeatedly sends contact verification signals spaced in time from one another according to the interval. In various embodiments the parameter may be an explicit indication (number of seconds or number of beacons between consecutive CVSs), or it may be implicit (derived from an ID of the fixed/Mode II or Mode I device or a frequency channel, in which the relevant ID is the parameter). A plurality of enabled Mode I devices each gets a device-specific list, and in one embodiment the interval is the same for each of them and the explicit indication is broadcast while in another the parameter is provided to each of them via unicast messages and the interval may differ. | 03-21-2013 |
20130046821 | Advanced Machine-To-Machine Communications - There are provided measures for advanced machine-to-machine communications. Such measures may exemplarily includes conducting machine-to-machine packet transmission of a machine device residing in a connected mode by using a bearer connection with a security context, causing transition of the machine device from the connected mode to an intermediate mode, in which the machine device is neither in connected mode nor in idle mode, after completion of the machine-to-machine packet transmission, and keeping the security context of the connection for the intermediate mode, and causing transition of the machine device from the intermediate mode to the connected mode after elapse of an inactivity period of the machine-to-machine packet transmission, and conducting machine-to-machine packet transmission of the machine device residing in the connected mode by reactivating the bearer connection with the kept security context. | 02-21-2013 |
