    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.

  • Publication number: 20200163147
    Abstract: In this invention, we disclose methods for enabling ad hoc cellular base station functionality within a user equipment when the connection quality between a base station and the user equipment is limited or nonexistent. These methods include measuring a connection quality between a user equipment and its serving base station. If the connection quality is below a threshold, the user equipment can enable its internal ad hoc cellular base station functionality. This is done by running a software within the user equipment that (a) checks the connection quality periodically, and (b) enables ad hoc cellular base station functionality of the connection threshold dips below a certain value. In one embodiment, that threshold could be the same threshold value that a user equipment would use if it were making a decision to handoff to another base station based on poor connection quality.
