The invention relates to a method and apparatus for simulating a system in a communications network as a linear system in order to obtain a prediction of the load of a resource in the system. Measurements obtained at m different points in time of the event intensity afor a number n of key events occurring in a reference system are used to form the simulation model, together with measurements of the total load L in the reference system at the m different points in time. An optimization problem, defined by the simulation model and a set of event intensities of the system-to-be-predicted in a scenario to be simulated, is solved in order to obtain a prediction of the total load of the system in the simulated scenario.

Method and apparatus for simulation of a system in a communications network

A method of controlling the rate of traffic flow through an Iub interface of a Radio Network Controller is described. The method includes obtaining a licensed rate, which defines the maximum throughput permitted through the Iub interface, at the Radio Network Controller. The rate of traffic flow through the Iub interface and all Iu interfaces of the Radio Network Controller is measured, and the extent to which packet switched traffic flow through the Iub interface exceeds the licensed rate identified. If the packet switched traffic flow through the Iub interface exceeds the licensed rate, packets are dropped from traffic flow through the Iub interface to reduce the traffic flow to the licensed rate.
