摘要

A network system (100), method and an access server (110) for data transfer between an application server (130) and a user terminal (140) across heterogeneous wired and wireless networks, the access server being functionally connected between the application server and the terminal for dynamically facilitating transfer of data therebetween, and holding information on features of the terminal and on radio resources available in the wireless network to comtrol transfer of data between the data server and the terminal in dependence on the held information, so as to optimize resource use in a composite radio environment.
