A calling party subscriber informs the serving telecommunications node (70a, 210) that the dialed called party number represents a mobile number. The serving telecommunications node then interrogates the home location register (HLR) (50) associated with the called party mobile station (10) to determine the current location of the called party mobile station. Upon determining the mobile switching center (MSC) (70b) currently serving the called party mobile station, the serving telecommunications node then directly establishes a call connection (170) with the serving MSC. The serving MSC then establishes a speech connection (120) over a radio channel with the called party mobile station traveling within its coverage area to enable the calling party terminal to communicate with the called party mobile station.
