    Abstract: This application discloses methods for creating self-organizing networks implemented on heterogeneous mesh networks. The self-organizing networks can include a computing cloud component coupled to the heterogeneous mesh network. In the methods and computer-readable mediums disclosed herein, a processor determines if a user equipment (UE) should hand over its service from a base station to a multi-radio access technology (RAT) node, based on heuristics including one or more of: a distance traveled over a time T1, an average speed over a time T2, a destination stored in internal memory within the UE, a speed limit measurement for a nearby road, a possible direction in which the UE could travel, a signal strength measurement for a servicing base station, and a signal strength measurement for the multi-RAT node. A position profile may be used to predict a future location of the UE.

    Abstract: This invention discloses a mesh network comprised of at least two dynamic base station nodes, wherein the two dynamic base station nodes comprise each a multiple radio access technology architecture, the multiple radio access technology architecture comprising: at least two radio access technologies for providing access to a core network, and an abstraction layer communicatively coupled to the at least two radio access technologies for receiving and converting data into protocol agnostic data, wherein the first and second dynamic base station nodes are configured to: in response to a query regarding environmental conditions from a computing cloud component, send an environmental condition to the computing cloud component, receive an instruction from the computing cloud in response to the computing cloud component having processed the environmental condition, and change an operational parameter in response to the received instruction. The first and second dynamic base station nodes support at least two of a 3G RAT, a 4G RAT, and a 5G RAT.

    Abstract: A method for topology hiding is disclosed, comprising: receiving, at a gateway, the gateway positioned between a core network and a radio access network, a configuration information request from a base station; analyzing, at the gateway, a topology of the radio access network, the radio access network including the base station; grouping, at the gateway, the base station into a first group based on the topology; sending, from the gateway to the base station, a grouping message to indicate that the base station be placed in the first group; and terminating connections from the core network to one or more base stations in the first group at the gateway as a back-to-back proxy, thereby hiding the topology of the radio access network from the core network.

    Abstract: A method is disclosed for improved tracking area planning and handling, comprising: assigning a single tracking area code to a plurality of eNodeBs at a messaging concentrator gateway, the messaging concentrator gateway situated in a network between the plurality of eNodeBs and the core network; storing, at the messaging concentrator gateway, at least one indicator of a last known location of a user equipment (UE) other than the single tracking area code; receiving a paging message from the core network at the messaging concentrator gateway for a UE; and performing a paging sequence using the at least one indicator to identify a set of eNodeBs to page the UE, thereby allowing larger tracking area list sizes to be used without increasing signaling traffic between the radio access network and the core network.
