Abstract

In a 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.

Claims

1. An information processing apparatus comprising:

a first communicator to communicate with a portable communication device through a first communication link, and

a second communicator to communicate with another information processing apparatus through a second communication link that is not routed through said portable communication device, the first communicator obtains address information of said another information processing apparatus to establish the second communication link via said second communicator, and the information processing apparatus is in communication with the another information processing apparatus through the second communication link,

wherein the second communicator is capable of sending a video image over the second communication link by using the address information.

2. A communication method for communicating with another information communication apparatus including a first communicator that communicates with a portable communication device through a first communication link, and a second communicator that communicates with another information processing apparatus comprising steps of:

at said first communicator, obtaining address information of said another information processing apparatus to establish a second communication link via said second communicator that is not routed through said portable communication device;

at said second communicator, communicating with said another information processing apparatus via the second communication link based on said address information; and

sending a video image by the second communicator over the second communication link by using the address information.

3. A computer-readable medium storing a computer program for implementing a communication method for communicating with another information communication apparatus including a first communicator that communicates with a portable communication device through a first communication link, and a second communicator that communicates with another information processing apparatus, said method comprising the steps of:

at said first communicator, obtaining address information of said another information processing apparatus to establish a communication link via said second communicator that is not routed through said portable communication device;

at said second communicator, communicating with said another information processing apparatus via the second communication link based on said address information; and

sending a video image by the second communicator over the second communication link by using the address information.
