1. A communication system using heterogeneous networks, the system comprising:
- means for implementing a mobile Voice over Internet Protocol (mVoIP) environment with an IP network including one of a Mobile Network Operator (MNO) and a private mobile network, and a Public Switched Telephone Network (PSTN), and making IP network access with a sender terminal and PSTN network access with a receiver terminal, wherein;
an application for supporting voice calls is installed based on the mVoIP environment on the sender terminal, but not on the reciever terminal, andthe IP network supports a plurality of different routes having different quality and cost,means for obtaining network state information about the IP network accessing the sender terminal, a condition of the IP network, a telephone number for the sender terminal, a telephone number for the reciever terminal, and a voice call option for the sender terminal through the application installed on the sender terminal when the sender terminal sends a call access request to the receiver terminal, wherein the voice call option for the sender terminal indicates wheather the sender terminal is set up to prioritize call quality or call cost, andmeans for setting up one of a lowest cost route and a best quality route between the sender terminal and the receiver terminal as a communication route, based on the network state information,wherein the communication route is formed in selective combination of the IP network for the sender terminal and the PSTN network for the reciever terminal.

8. A communication system using heterogeneous networks comprising:
-
a first media gateway that gets network access to a sender terminal over an IP network, wherein the IP network supports a plurality of different routes having different quality and cost; a second media gateway that gets network access to a receiver terminal over a PSTN; a message processing server that obtains network state information through an application installed in the sender terminal, the network state information including information about the IP network accessed by the sender terminal, a condition of the IP network, a telephone number for the sender terminal, a telephone number for the receiver terminal, and a voice call option for the sender terminal, wherein; the voice call option for sender terminal indicates whether the sender terminal is set up to prioritize call quality or call cost; and the application is not installed in the reciever terminal; and a route and call processing server that forms a communication route for one of communication cost and call quality by referring to the network state information, wherein the communication route is formed in selective combination of the IP network for the sender terminal and the PSTN for the receiver terminal. - View Dependent Claims (9, 10)
