Systems and methods for extending connectivity with a cellular network are disclosed herein. A UE may monitor a serving cell of the UE and a neighbor cell of the UE to determine whether there is a network condition wherein the UE is to transition to an out-of-service (OOS) state if it were to fall to a Radio Resource Control (RRC) Idle state. The UE may react by, before expiration of an inactivity period corresponding to a transition to an RRC Idle mode, initiating signaling activity with a radio access network (RAN) node of the serving cell. In other embodiments, the UE may determine, based on a number of secondary devices connected to the UE, to initiate signaling with the RAN node of the serving cell before expiration of an inactivity period and according to whether a maximum number of extensions of an extension activity period has been reached.

Enhanced cellular connectivity via opportunistic extension of RRC connected mode

Apparatuses, systems, and methods for a wireless device to perform detection and mitigation of data stalls. The mitigation may occur during and/or at initiation of a data connection. The wireless device may establish a data connection(s) with a network over a Wi-Fi or cellular interface and monitor the data connection(s) for a data stall condition(s)/hint(s). The wireless device may perform a remedial action(s) responsive to detection of a data stall condition(s)/hint(s), including initiating a service recovery of the cellular interface, initiating a radio access technology (RAT) upgrade procedure, and/or initiating a handover procedure to a neighbor cell.
