Abstract
After an initial call connection towards a called party mobile station, an originating exchange serving the calling party terminal receives an indication over the connected telecommunications network that the entered called party number is associated with a mobile station. Thereinafter, the serving originating exchange interrogates the HLR directly to determine the mobile switching center (MSC) currently serving the called party mobile station for subsequent outgoing call connection requests towards the called party terminal. After retrieving the roaming number representing the serving MSC for the called party mobile station, a direct call connection is established between the originating exchange and the MSC currently serving the calling party mobile station without establishing a trunk call connection back to the home Public Land Mobile Network (PLMN) associated with the calling party mobile station.
