COMMUNICATION SYSTEM, COMMUNICATION SESSION-SERVER-DEVICE, MEDIA DISTRIBUTION DEVICE AND DATA TRANSMITTING METHOD FOR COMMUNICATION SESSION

摘要

The system has mobile radiocommunication terminals (306, 307) e.g. personal computer, provided in respective communication networks (301, 302). The network (302) has a data distribution unit (312) distributing data to other radiocommunication terminals. The distribution unit receives data to be transmitted to one of the terminals, in a communication session frame and retransmits it to the radiocommunication terminal. The distribution unit receives a data to be transmitted to the other terminal, in the session frame and retransmits it to a central communication session server. Independent claims are also included for the following: (1) a communication session server unit in a communication network for establishing a communication session between communication terminals (2) a data distribution unit in a communication network for distributing data to communication terminals (3) a method for transmitting data in a frame of a communication session between two communication terminals of respective communication networks.
