A mobile architecture system includes a plurality of connection nodes each comprising an access interface and at least one network interface. A plurality of aggregation layer devices are each coupled to respective sets of connection nodes to form aggregation regions. A backhaul network is coupled to each of the aggregation layer devices, and a mobility entity is coupled to the backhaul network, wherein each of the connection nodes is configured to receive attachment requests from at least one user device. The aggregation layer devices are configured to assign IP addresses to user devices connected to connection nodes coupled to the respective aggregation layer devices. The aggregation layer devices are configured to determine IP routes from the backhaul network to the connection nodes based on the assigned IP addresses. The aggregation layer devices are further configured to notify respective connection nodes regarding the IP addresses assigned to connected user devices.
