A user interface control software system (,) has software components organized into distinct partitions (,) with a defined interface governing communications between components of different partitions. Preferably, the software components are organized into a core partition (,), a device specific partition (,), a feature enabler partition (,), and a signaling partition (,). The core partition (,) has software components that perform input handling, application interaction management, application control management, and output handling. The device specific partition (,) has software components for interfacing with user interface hardware in a manner specific to a particular type of communication device. The feature enabler partition (,) has software components that implement procedures for interacting with the user to perform a particular task. The signaling partition (,) manages procedures relating to a signaling protocol that requires user interaction. An interface protocol (,) governs inter-partition communications among software components of the various partitions.
