Abstract: The present invention relates to methods and means for creating a cellular radio communication system (100) out of a number of local radio networks (109, 110), e.g. piconets. The local radio networks (109,110) are unsynchronised with each other and uses a radio interface that has no broadcast channel, e.g. the Bluetooth radio interface. A control unit (108) is connected to each local radio network to provide the basic means and methods for a cellular radio communication system (100). Radio units (101-103) can attach and retain a connection to the control unit (108) via their respective radio node (104-107). The radio units (101-103) can also perform roaming, handover, measurments and fast connection set-ups in the system (100).

Abstract: A customized telecommunication service comprising a service related component, referred to as a service shell, and a number of customization parts open to customization by a service provider. The service shell is designed by a system vendor with due consideration taken to the fact that the service must not interfere in a non-desired way with other existing services. The service shell comprises customization points to which the customization parts are added. Each customization point comprises an individual customization interface defining the scope of actions open to customization in the service shell. The service provider selects, among the actions, those which will build the desired function of the customization part.
