Abstract
A method for handling input/output messages for plural call processing applications which reside on a processor subsystem of a mobile switching center. An input/output message having a message transport address owned by one of the call processing applications is received at a memory subsystem thereof. The call processing application owning the received address is the application which will later handle the received message. The received address is transferred to an interrupt handler which also resides on the processor subsystem. There, a call to the call processing application which owns the address received for the incoming input/output message is issued. In response thereto, the call processing application wraps the received message with an object to be used by the received message when it is to be handled by the call processing application and stores the wrapped message at a selected location within the memory subsystem. The call processing application then schedules itself for execution.
