A method for controlling the operation of a mobile station. The operation comprises camping which is modellable as a number of states (S1 to S4) with predetermined state transitions (S12 - S34) between them. Each one of the states corresponds to a set of locally varying features which the mobile station currently supports. The features comprise a first feature indicating whether the mobile station is in circuit-switched mode or packet switched mode, and a second feature indicating whether or not the mobile station is in localised service area (LSA) mode. For all combinations of the first and second features there is a corresponding state (S1 to S4), and for each one of these states there are two originating state transitions and two terminating state transitions, each one of the originating state transitions corresponding to a change in the respective feature. |
