The TOE is server service software that is deployed on CloudOS, which serves as a united network controller (UNC).

UNC authenticates mobile subscribers onto the network system and tracks active and idle subscribers on the network system. UNC pages mobile subscribers when it is triggered by new data arriving for an idle subscriber at the assigned Serving GW (gateway). When a subscriber attaches to an eNodeB, the eNodeB select a UNC. UNC in turn selects the Serving GW and the PDN GW that will handle bearer packets of the subscriber. There are procedures to relocate a subscriber to a new UNC (and potentially a new Serving GW), when an active or idle subscriber moves to a new area outside of the current UNC control.
