Telecommunications systems arrangement
First Claim
1. Arrangement for interconnecting a first communication system with a number of first terminals and a second communication system with a number of second terminals wherein the second communication system is a cordless access communication system and the first communication system is a cellular mobile communication system comprising at least one Mobile Switching Centre, the interconnecting arrangement comprising an interworking function means, wherein the interworking function means via the existing interface of the first communication system is connected to a second Mobile Switching Centre of the first communication system and via a second interface of the second communication system is connected to said second communication, systems the interworking function means interworks protocols so that the second interface is converted to the existing interface of the first communication, systems and the interworking function provides emulation of a Base Station Subsystem of the first communication system and a first terminal over said existing interface in a non-modified form.

Abstract
An arrangement interconnects a first communication system and a second communication system. The first communication system is a cellular mobile communication system. The second communication system is a cordless access system. The systems are connected via an interworking function which is connected to a Mobile Switching Center of the first communication system via an existing interface of the first communication system. The interworking function is connected to an access system of the second communication system via an interface of the second communications system.
