Abstract: The invention generally concerns the issue of providing connectivity between two different address realms, generally referred to as an inside realm and an outside realm, by establishing connections through an intermediate gateway. The gateway normally has a number of outside-realm gateway addresses for enabling representation of inside-realm nodes in the outside realm. In a first aspect, support for flexible outside-realm initiated connections is enabled by dynamically establishing new gateway connection states triggered, for each new connection, by a respective user-resource identifier query initiated from a corresponding outside node. In a second aspect of the invention, intelligent use of predetermined connection information in the process of setting up new gateway connection states makes it possible to significantly increase the number of connections that can be simultaneously supported by the gateway using a limited number of outside-realm addresses.

Abstract: A digital cellular mobile radio communication system includes a mobile station transmitting an information block and a set of base stations receiving information blocks corresponding to the transmitted information block at each base station in the set. This communication system contains an up link macro diversity system with a device in each base station for determining a quality measure representing the reliability of each respective received information block, and a decision device for choosing the received information block with the best quality measure as a common output information block of the set of base stations.
