1. A dual mode mobile station comprising:
- managing means for managing information independently of the mode of operation of the mobile station;
first linking means for linking to the interface of a mobile communication network, said first linking means comprising a radio resource manager for the mobile communication network;
second linking means for providing a link to the interface of a further communication network, said second linking means comprising a radio resource manager for the further communication network; and
means for coupling the managing means to the first linking means when the mobile station is in a first mode and to the second linking means when the mobile station is in the second mode such that the mobile station remains connected to the mobile communication network, while actual data is carried over the further communication network.

Abstract
A wireless intranet office (WIO) concept is disclosed, which integrates an IP based Intranet environment (27) and GSM network providing mobile telephones (21) with access to GSM through the GSM network or via the intranet. Access through the intranet to the GSM MSC (26) is provided by a WIO interworking unit (24) which may comprise several network entities (e.g. intranet mobile cluster (241), intranet location register (242), WIO gatekeeper (243), WIO gateway (244) and H.323 gateway). A dual mode terminal for such a system is also disclosed.
