1. mobile phone message disposal system comprises:

  • First bus;

    Second bus;

    First data processor, it can carry out Base-Band Processing, and is coupled to described first bus;

    AndSecond data processor, it is connected to described first bus and described second bus, comprise on-off circuit, internal bus, first external interface circuit and second external interface circuit, and have first operator scheme and second operator scheme as its operator schemeWherein said first external interface circuit is coupled to described first bus and is coupled to described internal bus in another terminal at a terminal;

    Wherein said second external interface circuit is coupled to described second bus and is coupled to described internal bus in another terminal at a terminal,Wherein said second data processor is provided in described first operator scheme by the information that is provided by described first data processor via described first bus, and controls the switching of described on-off circuit so that information is provided to described second bus,Wherein, described on-off circuit is connected to described second bus with a described terminal of described first external interface circuit rather than a described terminal of described second external interface circuit in second operator scheme of described second data processor,Wherein said second data processor is controlled the switching of described on-off circuit so that will directly be provided to described second bus via the information that first bus is provided by described first data processor in described second operator scheme.
