摘要： A scheduling method for controlling wireless transmission of an electrical data signal by an apparatus deployed within a predefined area is proposed, the method comprising controlling transmission of the data signal according to a preset policy such that, while a human belonging to a specific predetermined category is present within the predefined area, transmission of the data signal is suspended unless it is, or becomes, urgent. In this way, human exposure to EMF emitted by the apparatus can be reduced, since transmission is suspended while a human or particular human is within the predefined area unless the transmission is of an urgent nature. A particular embodiment aims to minimize human exposure to EMF emission from the operation of maehine-to-machine (M2M) devices in smart buildings, by actively reducing radio transmission of the M2M devices upon detection of a human in close proximity to these devices. A location-based scheduling policy can be made for various parts of the building. The scheduling policy can also be made to prioritize the EMF reduction for certain people, subject to a number of criteria, such as their health condition, past EMF exposure, or their EMF dosage information aggregated from multiple smart buildings.
摘要翻译：提出了一种用于通过部署在预定区域内的装置来控制电数据信号的无线传输的调度方法，所述方法包括根据预设策略来控制数据信号的传输，使得属于特定预定类别的人是存在于预定义的区域内，数据信号的传输被暂停，除非是或者变得紧迫。以这种方式，由于传输被暂停，而人或特定的人在预定义的区域内，所以可以减少由该设备发射的EMF的人类暴露，除非传输是紧迫的。特定实施例旨在通过在检测到这些设备附近的人的主动地减少M2M设备的无线电传输时，将人类暴露于智能建筑物内的机器（M2M）设备的操作中的EMF发射最小化。可以对建筑物的各个部分进行基于位置的调度策略。还可以根据许多标准（如健康状况，过去的EMF暴露或多个智能建筑物聚集的EMF剂量信息）来确定某些人的EMF减少优先级。

摘要： A wireless communication method to provide mobility support of UEs (12) that are served by mobile relay base stations (14), by providing handover of a UE(12) for data traffic only between two mobile relay base stations. This is achieved by information exchanging between the source and target mobile relay stations of the concerned UE in handover, and/or the corresponding donor base stations (13, 11) if applicable. The handover is triggered by any of the following situations: (i) based on UE's measurement report, the signal quality of a neighbour cell is much better than the current serving cell; (ii) based on the measurement of the serving mobile relay base station, the signal quality of the link to the UE is worse than a certain threshold; or (iii) based on the measurement of the serving mobile relay base station, the signal quality of a neighbour cell (potential donor base station) is much better than the current donor base station.

摘要： A method of determining power source switching for a hybrid electric vehicle, HEV (100), based on its battery (18) status and pollution information along the planned route. The driver or the HEV on-board computer (10) then switches to a reduced-emission running mode such as electric-only propulsion when the observed pollution is above a certain threshold, The method can either be implemented within the HEV on-board computer (10) to perform the switching automatically, or to display the suggested switching operation to the driver. In one embodiment a centralized entity (20), for example a traffic and pollution management control centre within a Smart City which has means of communicating with and locating the HEV (100), as well as access to environmental and congestion parameters, provides a power source switching indication to the driver or the HEV on-board computer (10). Alternatively the central entity passes on the pollution and congestion information to the HEV on-board computer (10), which then determines the power source switching.

摘要： A cellular mobile communications network includes a base station controller (30) and an array of base transceiver stations (20), each having a communications path (5) connecting it to the base station controller (30), such that when an uplink signal is received from a mobile station (10) of the network by a plurality of the base transceiver stations (20) of the array, each base transceiver station (20) of the plurality can transfer the received uplink signal via its communications path (5) to the base station controller (30). The communications paths (5) are assessed according to one or more predetermined characteristics, and based on this assessment, at least one base transceiver station (20) of the plurality is prevented from transferring the received uplink signal to the base station controller (30). In such a cellular mobile communications network, if, for example, a particular communication path (5) is experiencing heavy traffic, then further congestion can be prevented by not sending further signals along that path. Network operating costs can also be reduced by diverting traffic away from costly communications paths (5).
