Abstract
in a telecommunication network structure, all functions related to traffic control, including functions for controlling, originating and terminating connections, take place in a mobile service control point while the physical set up of the connections take place in mobile service points which are subordinated to the mobile service control point. Subordinated units are connected to each mobile service point with trunks. A signal net is transferring traffic control signals, including connection control signals, to the subordinated units in which the connections are made, using the trunks.
