A radio base station has a monitor (31), memory (33, 49) and one or more resources (35(i), 37(j), 39(k), 41(m), 43(n), 45(o), 47(p)). The memory (33, 49) is connected to the monitor (31) and stores tasks and data. Each of the resources (35(i), 37(j), 39(k), 41(m), 43(n), 45(o), 47(p)) is connected to the monitor (31) and performs a function or executes a program. The tasks are stored in an XML format.
