A host on the LAN may perform a packet data communication with an external host via the routing means and the mobile station. Translation means is connected to the routing means for the temporary translation of a locally defined network layer address assigned to a host on the LAN into a globally defined network layer address when the host on the LAN performs a packet data communication with an external host.

Method and an arrangement in a mobile radio system

A communications network and method for screening incoming circuit switched calls directed to a mobile terminal operating in packet switched mode. The communications network includes a circuit switched network and a packet switched network. A called party uses the mobile terminal to transmit to the packet switched network a screening list containing at least one listed phone number. The packet switched network uses the screening list to inform the called party whenever an incoming circuit switched call of a calling party has a phone number matching anyone of the listed phone numbers.
