CONTROLLING LOCKING STATE TRANSITIONS IN A TERMINAL

摘要

A method and a control module for controlling locking state transitions in a terminal are described, wherein said terminal is configured for checking said transition in accordance to one or more state transition rules and wherein the method comprises the steps of : providing at least one one-way writable memory location comprising first state information associated with a first locking state of said terminal; receiving a request for a transition to a second locking state, said request comprising second state information associated with said second locking state; on the basis of said first and second state information and said transition rules checking whether said requested transition is allowable or not; and, storing said second state information in said one-way writable memory if said requested transition is allowable according to said state transition rules.
