A collapsed or compact mobile architecture system includes connection nodes each comprising an access interface and at least one network interface; a backhaul network coupled to each of the connection nodes; and a mobility control unit coupled to the backhaul network. The mobility control unit comprises an Internet Protocol (IP) address server. Each of the connection nodes is configured to receive attachment requests from at least one user device. The mobility control unit is configured to receive first control plane signals from the connection nodes based on the attachment requests and transmit second control plane signals to the connection nodes based on the attachment requests. The mobility control unit is further configured to assign an IP address to each of the at least one user devices, based on the receive first control plane signals.
