COMMUNICATION SYSTEM, ROUTE SELECTION APPARATUS, AND ROUTE SELECTION METHOD |
摘要 |
A communication system in which a plurality of communication networks are interconnected, the communication system including a plurality of inter-communication network connections that include an inter-communication network connection by a first circuit performing communication by a first protocol and an inter-communication network connection by a second circuit performing communication by a second protocol, including: a route selection apparatus that is provided in a communication network that is connected to another communication network by the first circuit, and that is connected to another communication network by the second circuit; and a connection determination apparatus that is provided in a first circuit connection network that is the other communication network connected with the communication network by the first circuit, wherein, when the route selection apparatus receives a connection request signal transmitted from a user apparatus in the communication network, the route selection apparatus transmits the connection request signal to the first circuit connection network, and wherein, when the route selection apparatus receives a connection failure signal, from the connection determination apparatus, indicating that an incoming destination of the connection request signal is not a user apparatus of the first circuit connection network, the route selection apparatus transmits the connection request signal to a communication network of an incoming destination via the second circuit. |

1. A communication system in which a plurality of communication networks are interconnected, the communication system including a plurality of inter-communication network connections that include an inter-communication network connection by a first circuit performing communication by a first protocol and an inter-communication network connection by a second circuit performing communication by a second protocol, comprising:
a route selection apparatus that is provided in a communication network that is connected to another communication network by the first circuit, and that is connected to another communication network by the second circuit; and a connection determination apparatus that is provided in a first circuit connection network that is the other communication network connected with the communication network by the first circuit, wherein, when the route selection apparatus receives a connection request signal transmitted from a user apparatus in the communication network, the route selection apparatus transmits the connection request signal to the first circuit connection network, and wherein, when the route selection apparatus receives a connection failure signal, from the connection determination apparatus, indicating that an incoming destination of the connection request signal is not a user apparatus of the first circuit connection network, the route selection apparatus transmits the connection request signal to a communication network of an incoming destination via the second circuit. |
