1. An apparatus, comprising:
- a managing module adapted to manage information independently of the mode of operation of a mobile station;
a first linking module adapted to link to the interface of a mobile communication network, said first linking module comprising a radio resource manager for the mobile communication network;
a second linking module adapted to provide a link to the interface of a further communication network, said second linking module comprising a radio resource manager for the further communication network; and
a coupling arrangement adapted to couple the managing module to the first linking module when the mobile station is in a first mode and to the second linking module when the mobile station is in a second mode such that, when the mobile station is in the second mode, 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.
