Abstract: Methods and apparatus, including computer program products, are provided for dynamic ungrouping. In one aspect there is provided a method. The method may include determining, at a user equipment, whether a packet transmission to a network will cause the user equipment to transition from a first power consumption state to a second power consumption state; sending, by the user equipment, the packet, when the packet transmission will not cause the user equipment to transition to the second power consumption state; sending, by the user equipment, the packet, when the packet transmission will cause the user equipment to transition to the second power consumption state and the packet is delay intolerant; and delaying, by the user equipment, the packet transmission, when the packet transmission will cause the user equipment to transition to the second power consumption state and the packet is delay tolerant.

Abstract: In accordance with an example embodiment of the present invention, there is provided an apparatus comprising a user interface receiver configured to receive at least one indication of user activity, at least one processing core configured to initiate packet-based connectivity over a radio communications interface responsive to the at least one indication of user activity, wherein the at least one indication of user activity comprises at least one indication relating to operating a web browser, the at least one indication not indicating a user request to fetch a resource for display on the browser.
