The main features are as following:  Persistent PPP sessions across power-down events  m2m capability indicators  Longer timer-based registration timer value for m2m devices  Longer SCI (similar mechanism in HRPD)  Skip overhead channel read (similar mechanism in HRPD)  Fast connection setup  Direct Channel Assignment (similar mechanism in HRPD)  R-EACH(coupled with F-PCH) and RL Data-over-Signaling —— Lower signaling load and higher network capacity + Lower network and module cost + Improved module battery life Background 2

Some enhancements in 1x, such as lower-rate data support, should be considered in HRPD.  Some operators will re-deploy their CDMA spectrums when they move their current networks to 4G LTE. The available resource for CDMA might gradually decrease. More optimization for spectrum efficiency and transmission efficiency should be considered.

Application signallings occupy amount of network capacity.  Supporting lower-rate data in access/connectionless channel  Supporting soft combining in access/connectionless attempt to increase SINR and reduce re-transmission  Increasing access/connectionless channel transmission efficiency, e.g. MAC layer header compression  Optimized access/connectionless channel data rate selection Access congestion mitigation  Persistent test during intra-sequence access probes Saving battery life is important for both M2M devices and smart phones  Deep sleep and wake-up by trigger instead of periodic monitoring Enhancement Proposals
