Abstract
In a routing control apparatus and method for a composite network, a decision is automatically made as to whether a connection to a public telephone network via a leased line is allowed, by examining the dial information entered from a calling party and judging the communications applicable to the receiving node, the type of communication requested, and other factors. A connection judging unit extracts, from the dial information entered by the calling party, a node identifier CC for specifying the receiving node and a connecting type identifier V/F for directing the initiation of judgment as to whether a connection to a public network via a leased line is allowed and for providing a parameter for determining the type of communication requested, and which judges, based on the extracted identifiers CC and V/F, whether a connection to a public telephone network accommodating the called party is allowed via a leased line destined for a receiving node. When it is judged that connection to the public telephone network via a leased line is allowed, the call form the transmitting node is connected via the receiving node to the public telephone network that accommodates the called party.
