Dynamic aggression management of cellular connectivity

A method, comprising:

• by a wireless user equipment (UE) device:
• determining one or more conditions currently present for the UE, wherein the one or more conditions comprise at least a battery level condition of the UE;
• selecting whether to implement cell barring on an individual cell basis or a cell frequency basis based at least in part on the one or more conditions determined to be currently present for the UE;
• and
• performing cell barring according to the selection of whether to implement cell barring on an individual cell basis or a cell frequency basis.

A wireless user equipment (UE) device, comprising:

• a radio;
• and
• a processing element operably coupled to the radio;
• wherein the radio and the processing element are configured to:
• receive an application data request from an application layer of the UE;
• and
• attempt to establish a cellular connection to service the application data request according to a plurality of connection attempt parameters,
• wherein at least one of the connection attempt parameters are modified under one or more predetermined conditions, wherein the one or more predetermined conditions comprise at least a battery level of the UE being below a battery level threshold, wherein connection attempt parameters modified under the one or more predetermined conditions comprise one or more of:
• whether to bar cell frequencies or individual cells based on cell registration failures for cells of one or more radio access technologies (RATs);
• a cell registration failure threshold for disabling use of one or more RATs and/or a length of time for disabling use of the one or more RATs if the cell registration failure threshold is met;
• application data request throttling threshold and/or length parameters;
• or
• one or more application data request failure threshold parameters.
