A data traffic responsive battery-saving approach for a wireless user equipment (UE) device such as an data packet capable cellphone incorporates flexible discontinuous transmission and reception (DTX-DRX) when in Long Term Evolution (LTE) active mode as dictated by an evolved radio access network (RAN) such as an evolved base node (eNode B). A UE device requests are made on unsynchronized random access channel (RACH). Lengthening a duration of DRX and reducing requirements for synchronization uplink transmissions results in power savings of up to 75%, as well as creating opportunities for reducing interference and for allocating additional time slots for data. This power savings is compatible with other downlink scheduling proposals, with control channel-less Voice-over-IP (VoIP), and need not target those UE devices in bad radio conditions. Legacy UE devices that can interact with the eNode B by being capable of radio resource control (RRC) signaling continue to be compatible.
