ABSTRACT:
The invention relates to a method for handling a request by a first communication device11connected to a network of a communication system to establish a packet switched session with a second, wireless communication device12, which session requires the second communication device12to be connected to a network which enables the establishment of the session. In order to enable an enhanced handling of such a request, it is proposed that it is first determined whether the second communication device12is currently connected to such a network. In case it is determined that the second device12is not connected to such a network, a corresponding indication is transmitted to the first device11. The user of the first device11is then informed via the first device11that the requested session cannot be established. The invention relates equally to a communication system enabling such a method and to corresponding elements11, 13of such a system.
