Abstract: A method and a wireless device (100) for handling transmission of data. The cost for transmitting the data from the wireless device (100) can be reduced or even minimized by delaying (1:3) transmission until the transmission cost becomes lower, provided that the data can wait without becoming obsolete or useless at the receiving side. This is made possible by determining a delay tolerance of the data and determining a cost prediction for transmission (1:6) within said delay tolerance, e.g. when a cheaper connection (1:4) is used. Advantages may include reduced price to pay for the transmission, less energy consumption, and avoided usage of precious radio resources and network resources at times when the traffic load is high.

Abstract: A broadcasting method has been developed that no longer uses the point-to-point measurements that causes the bottlenecks due to the number of measurements that need to be taken increasing non-linearly with the number of nodes. In addition, not all nodes need to emit. This results in significantly less expensive devices that can be paired with emitting nodes in the infrastructure. The energy emitted by the group is lowered and there is significantly less bandwidth that is used compared to current systems. This system is designed to synchronize remote clocks and localize a group of nodes and comprises at least 4 ranging nodes equipped with a clock, the capability to send and receive messages, the capability to time-tag messages, the capability for the nodes to compute the two sheeted hyperboloids from the emissions of other nodes, and the capability of combining multiple hyperboloids to solve the localization equations.

Abstract: Disclosed is a packet processing method and system, and a device. A status value used to identify a topology status of service nodes at a specified time is preconfigured for a packet in a packet flow, so that when a service node in a next hop is selected for the packet, selection is performed not based on a topology status of current actual service nodes in the next hop, but based on the topology status, which is identified by the status value, of the service nodes at the specified time. As long as status values carried in packets in a same packet flow are the same, even if a topology status of service nodes changes, a same service node can still be selected for the packets in the same packet flow, thereby avoiding a problem of diversion of the packets in the same packet flow.

Abstract: Embodiments of the present invention disclose an access network node, a core network node, and a paging method, and relate to the communications field, so as to resolve a problem that an M2M service cannot be normally used because a network side cannot determine whether a coverage enhancement technology needs to be used in a paging process. A specific solution is as follows: A communications interface is configured to receive a first packet paging message sent by a core network node; a processor determines, according to the first packet paging message received by using the communications interface, that a terminal is an M2M terminal; and a transmitter sends a coverage-enhanced second packet paging message to the terminal. The present invention is used in a paging process.

Abstract: The present disclosure provides a data shifting operation apparatus having multiple operation modes that includes a preprocessing circuit, a first and a second shifting circuits and a multiplexer. The preprocessing circuit stores an input data group, having a data amount equal to a desired data amount M, to an under-operation data group, having the data amount equal to a maximum usage data amount N, from a most significant bit, and receives a shift amount S to calculate a total shift amount. The first and the second shifting circuits respectively cyclically shift the under-operation data group for the shift amount and the total shift amount to generate a first and a second shifted data groups. The multiplexer selects S data from the most significant bit of the second shifted data group and (M?S) data from the (N?S)-th bit of the first shifted data group to output a final shifted data group.

Abstract: A dual-radio AP including both a high-power (e.g., Wi-Fi) radio and a low-power (e.g., BLE) radio may support an assisted wakeup service for a power-limited dual-radio mobile device (STA). The power-limited STA may register with the AP for the assisted wakeup service, and may then disable its Wi-Fi radio (or otherwise initiate a lower-power mode). The power-limited STA may receive a BLE communication indicating the AP has pending Wi-Fi transmissions or updates applicable to the power-limited STA. In response, the power-limited STA may turn on its Wi-Fi radio and receive the pending transmissions or updates from the AP. If an AP does not include a low-power radio, then a high-power/low-power dual-radio STA that is not power-limited may serve as an assisted wakeup service proxy. The proxy may scan and trace the Wi-Fi beacons from the AP, and generate the BLE communication to the power-limited STA on behalf of the AP.
