<p>The present invention relates to an information transmission method in a communication network comprising an information provider device communicating in a first network, a plurality of user terminals for receiving information provided by the information provider device communicating in a second network, and a transfer device for routing information between the information provider device and user terminals. There is registered at least a network address of a user terminal in correlation with a user management number for the user terminal. The user management number is used for identification of the user terminal only in the first communication network. The user management number has a one-to-one correspondence with the network address for the user terminal and is different from the user terminal. At the transfer device, there is received from the information provider device information supplied with designated user management number as a desired designation. Then, there is determined a network address that corresponds to the designated user management number, and at least a part of the information is transmitted to the determined network address.
