Multiple communication system, exchange, and terminal device
First Claim
1. A multiple network communication system comprising:
- a plurality of mobile communication networks and at least one terrestrial communication network, each of the plurality of communication networks being connected to each other via exchanges; and
a plurality of terminal devices, including at least a plurality of mobile terminal devices each belonging to a respective one of said plurality of mobile communication networks, and at least one terrestrial communication device belonging to said terrestrial communication network;
each of said plurality of terminal devices being capable of communicating with another terminal device via said exchanges, wherein said mobile terminal devices are capable of moving from an area corresponding to the mobile communication network to which said mobile terminal devices belong to an area served by another one of said mobile communication networks;
whereinupon originating a call to a mobile terminal device, a terminal device originating said call sends to its associated exchange, in addition to a destination telephone number of said called mobile terminal device, a designated call incoming code specifying a destination mobile communication network on which to attempt to connect to said called mobile terminal device; and
said associated exchange sends the destination telephone number to the destination mobile communication network designated by said call incoming code to connect said called mobile terminal device with the call originating terminal device via said destination mobile communication network.

Abstract
A multiple communication system is comprised of a plurality of communication networks including mobile communication networks. The plurality of communication networks are connected to each other by exchanges. Terminal devices including mobile terminal devices belong to respective communication networks and can communicate with each other via the exchange in the communication network in which the terminal device is accommodated. When a call is originated, the terminal device sends a designated call incoming code for specifying a destination mobile communication network for connection. The exchange connects to the mobile communication network corresponding to the designated incoming call code received from the terminal device.
