摘要： Methods and apparatus enabling seamless vertical handover between radio networks. In one embodiment, a mobile device in communication with multiple networks, scans the networks for suitable candidate networks for handover. If the mobile device experiences signal loss below a first threshold, the mobile device primes itself for a handover. Once the signal loss drops below a second threshold, the mobile device executes the handover. The priming of the device enables very low level hardware to detect and initiate the handover (rather than higher layer software). Consequently, software applications data loss is greatly improved (i.e., reduced) during a vertical handover.

摘要： A mobile communication device comprises a plurality of spatially and/or polar diverse antenna configurations. Signals received by each of the plurality of antenna configurations are combined in a combiner and passed to a rake receiver that can be configured to combine the signals received by each of the plurality of antenna configurations for further processing. The mobile communication device can comprises a signal adjusting network that can be configured to adjust the phase and/or magnitude of signals being received by one of the antennas.

摘要： An apparatus and method are presented for combining electrical signals. The apparatus includes a phase-shift distributed element with an input to accept a first signal and an output to supply the first signal with a phase-shift; and a filter with a first signal port connected to the phase-shift element output, a second signal port to accept a second signal, and a third signal port to supply combined and filtered first and second signals. The phase-shift element has a signal path with a predetermined length and the phase-shift element output supplies the first signal with a phase angle shift responsive to the length of the signal path. In one example, the phase-shift element is formed from monoblock and coaxial elements, either singly or in combination, and is a tank circuit resonator in the filter.
