Patent ID: 11277797

Abstract:
A method and system for controlling uplink-path switching of a user equipment device (UE) when the UE has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node, where one of the connections defining a primary uplink path of the UE and an uplink-path-switch control process dynamically controls switching which one of the air-interface connections is the UE's primary uplink path. An example method includes (a) detecting that both (i) the switching of which one of the air-interface connections is the UE's primary uplink path has been occurring at a threshold high rate and (ii) the UE's remaining battery energy threshold low, and (b) responsive to at least the detecting, disabling further switching of which one of the air-interface connections is the UE's primary uplink path while the UE maintains the co-existing air-interface connections.
