Communication system, method and controller for routing calls within private networks distributed among geographically distant zones
First Claim
1. A zone-specific controller (GK) of a communication system (SYS) including in each of a plurality of geographically distant zones (ZA, ZB, ZC) a different zone-specific controller (GK) and one or more subscriber terminals (EP) connected to each other via a zone-specific bus network (BUS-A, BUS-D, BUS-C), said zone-specific bus networks being connected to each other via at least one interconnection network (WAN), wherein said zone-specific controller (GK) controls the signaling traffic between the subscriber terminals (EP) in each zone and between different zones and comprises:
- a) a controller characteristics memory (CCM) for storing at least a private network identifier (PNID) of a private network (PN) to which said zone-specific controller (GK) and its connected subscriber terminals (EP) belong;
b) a private network configuration memory (PNCM) for storing the private network configuration at least of the private network identified by the stored private network identifier (PNID);
c) a private network configuration determining means (PNDM) for communicating (GRQ, GCF, GRJ) with all other controllers (GK) of the communication system (SYS) to determine the private network configuration including those controllers (GK) and subscriber stations (EP) in other zones (B, C) which belong to the private network (PN) identified by the stored private network identifier (PNID) and to store corresponding private network configuration information (TA;
RA;
CNCT) in said private network configuration memory (PNCM).

Abstract
A controller (GK) of a communication system (SYS) including in each of a plurality of geographically distant zones (ZA, ZB, ZC) a zone-specific controller (GK) and one or more subscriber terminals (EP) comprises a controller characteristics memory (CCM) for storing at least a private network identifier (PNID), a private network configuration memory (PNCM) for storing the private network configuration, a private network configuration determing means (PMDM) for communicating with other controllers (GK) of the communication system to determine the private network configuration and a call router for routing a call setup message received from a subscriber terminal (EP-A3) in one zone (ZA) to another subscriber terminal (EP-B2) of another zone (ZB). Before setting-up a call or at repeated time intervals the private network configuration including the controllers and subscriber stations in all zones (ZA, ZB, ZC) which belong to the private network identified by the private network identifier (PNID) can be determined and this private network configuration is used for determining the location of the respective controller which serves the called subscriber station (EP-B2).
