    摘要： A method in a communication terminal, comprising:
    determining whether a caller identity of an entity is associated with a subscription to presence information associated with the entity, where the presence information comprises media data for output through an output unit in the communication terminal,
    determining, if the caller identity was determined to be associated with a subscription to presence information, whether the media data is present in the terminal, and,
    if the media data is present in the terminal, outputting the media data through an output unit in the communication terminal.

    摘要： A ringing signal generator in which a low-level reference ringing signal, generated by a reference waveform generator (101), is amplified by a delta-modulation power amplifier (106, 108). The low-level reference signal is digitally encoded using delta-modulation techniques to generate a high-level digital signal. The high-level digital signal is filtered (421) to remove the high-frequency components therefrom and to decode the digital signal to form the high-level ringing signal that has the same shape and frequency as the reference signal. The delta-modulation power amplifier generates the ringing signal by comparing (401) the reference ringing signal (Ei) with an analog feedback signal (Ef) reconstructed from the high-level digital signal. The resultant binary error signal (E$(1,4)$), representing the polarity of the difference between the reference and the feedback signals, is applied to a logic circuit (405) which samples the error signal at a clock rate substantially higher than the frequency of the ringing signal, and generates two binary control signals (+SW, -SW) based upon the error signal at multiple clock instants. These control signals open and close the switching elements (411, 412, 413, 414) in a bridge switch (410) to generate the high-level digital signal.
