Claim:
1. A method for initiating discontinuous reception (DRX) operation by a user equipment (UE) operating in a wireless communications network, the method comprising: Monitoring applications running on the UE to identify at least one inactivity trigger event associated with at least one of the applications; Determining, by the UE, to initiate the DRX operation based on the identified inactivity trigger event and device characteristics information associated with the UE; Signaling the device characteristics to a non-access stratum (NAS) through NAS parameters, wherein the device characteristics comprise delay tolerance of data to be sent or received by the UE and identification of the UE as a machine-to-machine (M2M) type of device executing an M2M type of application and the device characteristics are obtained from a home subscriber server (HSS) or home location register (HLR) via a mobility entity (MME) gateway; and Communicating by the UE to an enhanced node B (eNodeB) initiation of the DRX operation prior to the UE switching to the DRX operation; Wherein the monitoring is performed in an energy-aware event monitor component of a UE application layer and the determining is performed in an application-radio cross layer application programming interface (API), included in a protocol stack of the UE, for translating application information from an application layer into a format usable by one or more of a radio resource control (RRC) layer and medium access control (MAC) layer, wherein the energy-aware event monitor component, the application-radio cross layer, an application-aware DRX trigger component of the one or more of a radio resource control (RRC) layer and medium access control (MAC) layer, and the NAS parameters are used by the UE in negotiating DRX parameters for the DRX operation.
