A method and mechanism provide for online testing, replacement, upgrading and modification of portions of a radio communications system. A task controller (200) tests and replaces online elements in a task unit. The task unit is generally comprised of a task input queue (208), a task output queue (210), a subagent (204) and a task (206). The task controller (200) checks the functioning of the queues (208) and (210). If either or both are functioning improperly, the task controller (200) may replace one or both online. If both are operating properly, the task controller (200) tests the task (206). If the task (206) is improperly functioning, the task controller (200) replaces the task (206) with another task (402) online. The task controller (200) may further replace tasks to upgrade portions of the system.
