Abstract
A Home NodeB (HNB) is provided that can be triggered to dynamically change its operating radio parameters, such as its transmission frequency or its primary scrambling code without having to be rebooted and which communicates the changed operating parameters to the mobile user devices served thereby. In this way a seamless changeover of the operating parameters can be provided that is transparent to users. The HNB may be triggered to change operating parameters by the mobile operating network or by an internal procedure.
