In a communication terminal capable of selecting a communication medium best suited for the service settings and communicating via the selected medium, service executors include necessary applications and act as a trigger for the start of service provision. A communication controller has functions of detecting communication media, establishing connection therewith, selecting the most appropriate communication medium in response to service requests from the service executors, and performing communication. All communication between the service executors and communication nodes is performed via the communication controller, which acts as a proxy for the service executors. The communication controller sets and stores correspondence information between keywords contained in domain names and communication media to be used, between destination IP addresses and physical ports to be used, and between communication media and physical ports.
