Managing utilisation of interconnections between communications networks by routing local connections via interconnection to second network and back to first network

摘要

Data is transmitted between a calling and a called (9) telecommunications unit, firstly via the first communication network (3), which carries local communications, and then transferred to the second communication network (6). To achieve the desired utilisation of the interconnections, the telecommunications connections for local communications are routed from the first network via an interconnection (5) to the second network, and from this network back to the first network, or further to a third communications network. The first communications network then switches the connection to the called telecommunications unit (9). An Independent claim is included for a communications system for managing the utilisation of interconnections.
