Abstract

When a line for communication of audio signals between first and second portable-telephone devices through a first portable-telephone base station, a second portable-telephone base station and a portable-telephone line network has been connected, IP addresses are exchanged. The IP addresses are required for communicating image data by first and second terminal adapters associated with the first and second portable-telephone devices respectively through an OCN. Image data is then transmitted to the IP addresses received in the communication through the OCN. To put it concretely, an image of the user of the first portable-telephone device is transmitted by the first terminal adapter through the OCN to the IP address of the second terminal adapter to be displayed by a second television receiver associated with the second terminal adapter. By the same token, an image of the user of the second portable-telephone device is transmitted by the second terminal adapter through the OCN to the IP address of the first terminal adapter to be displayed by a first television receiver associated with the first terminal adapter. Thus, by merely taking a portable-telephone device to a place like a store selling home electrical appliances including a television.

Claims

1. A communication device for communicating with another communication device, said communication device comprising:

a first communicator that communicates by using a first communication link to obtain address information of the another communication device; and

a second communicator that communicates with the another communication device by using a second communication link,

wherein said second communicator obtains address information of said another communication device from the first communicator to establish said second communication link,

wherein the second communicator sends an ID of the communication device for authentication of said communication device and, when the communication device is authenticated, said second communicator communicates with said another communication device via said second communication link based on said address information.

2. A communication method for communicating with another communication device including a first communicator that communicates by using a first communication link and a second communicator that communicates by using a second communication link, said communication method comprising the steps of:

at said second communicator, obtaining the address information of said another communication device from the first communicator to establish said second communication link, and

at said second communicator, communicating with said another communication device via said second communication link based on said address information.

3. A program storing medium storing a computer-readable program that when executed on a processor causes the processor to execute a communication method for a communication device communicating with another communication device said communication device including a first communicator that communicates by using a first communication link and a second communicator that communicates by using a second communication link, said computer program implementing the steps of:

at said second communicator, obtaining the address information of said another communication device from the first communicator to establish said second communication link,

sending an ID of the communication device for authentication of said communication device and

at said second communicator, when the communication device is authenticated, communicating with said another communication device via said second communication link based on said address information.
