摘要： A positioning module positions a location of a mobile communication apparatus. A processor determines whether the location falls within a predetermined range, wherein the predetermined range is equal to or greater than an effective communication coverage of a neighboring base station. If the processor determines that the location is within the predetermined range, a signal detection module measures the signal from the neighboring base station. By detecting the signals of the neighboring base stations earlier, the present invention is able to function while the mobile communication apparatus moves at high speeds and successfully switch the connections between the base stations.

摘要： A mobile node (MN), a take-over point of attachment (PoA) and handover methods thereof for use in a heterogeneous wireless network system are provided. The heterogeneous wireless network system comprises a gateway, a first wireless network and a second wireless network which is heterogeneous to the first wireless network. The first wireless network and the second wireless network comprise the take-over PoA and an original PoA respectively. The take-over PoA and the original PoA have an overlapping service area. The MN receives a network service from the gateway via the original PoA so far. As soon as the MN enters the overlap service area, the MN builds a link with the take-over PoA in the data-link layer immediately so that the original PoA may handover to the take-over PoA without interrupting the network service.

摘要： A power-on-detection (POD) circuit includes first and second comparators, a voltage divider, a detection circuit coupled to a first voltage source node and the voltage divider, and logic circuitry coupled to outputs of the first and second comparators. The detection circuit outputs a control signal identifying if a first voltage source node has a voltage potential that is higher than ground. The control signal turns on and off the first and second comparators, which are respectively coupled to first and second nodes of the voltage divider and to a reference voltage node. The logic circuitry outputs a power identification signal based on the signals received from the outputs of the first and second comparators.

摘要： A mobile node (MN), a WiMAX base station (BS), a Wi-Fi access point (AP) and a handover method therefore, for use in a heterogeneous wireless network system, are provided. The heterogeneous wireless network system comprises a gateway. The WiMAX BS and the Wi-Fi AP can interchange messages with each other via the gateway. There is an overlap service area between the WiMAX BS and the Wi-Fi AP. The MN accepts a network service, which is provided by the gateway, via the WiMAX BS. When the MN enters the overlap service area, it may handover to the Wi-Fi AP without interrupting the network service so that the gateway may provide the network service for the MN via the Wi-Fi AP.
