An actuator for an oscillator which can control the fluctuation of the oscillation of an electrostatic driven oscillator such as the detection error by controlling the fluctuation of the amount of the noise mixed into a displacement detecting signal. In an example, an electronic signal routing structure includes a substrate. The embedded multi-media system is enabled as receiving an enabling signal and providing a first device signal. Further, the system and method takes into account unique data source characteristics in order increase resilience to network error while minimizing overhead. A mobile station and a mobile network gateway node each include a mapper for mapping an individual application flow to one of a circuit-switched network and a packet-switched network bearer depending on the quality of service requested for the individual application flow.
