2 Title: Type: Arial Size : 30-32pt Color : The theme blue Text (1-5 Level): Type : Arial Size : 28~12pt Color : Black G91, B170 G137, B207 G174, B239 G171, B189 CDMA2000 1xRevF specifications, which are optimized for M2M devices and applications, have been published. 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

3 Title: Type: Arial Size : 30-32pt Color : The theme blue Text (1-5 Level): Type : Arial Size : 28~12pt Color : Black G91, B170 G137, B207 G174, B239 G171, B189 Motivation 3 Based on CDG document, by 2016, 4.6 billion shipped devices for smart systems and over $750 billion in smart systems and value- added services revenue are expected.  M2M devices and applications  Multiple applications in smart phones, such as Instant Messaging (IM), emails, stock, etc. which have similar characteristics as that in M2M applications Given the benefits of spectral efficiency, ubiquitous coverage, low latency, high security levels and low total costs of ownership, CDMA has become a good choice for smart devices and applications.  1x/HRPD dual mode devices prefer to transmit the packet data through cdma2000 HRPD network. 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.

4 Title: Type: Arial Size : 30-32pt Color : The theme blue Text (1-5 Level): Type : Arial Size : 28~12pt Color : Black G91, B170 G137, B207 G174, B239 G171, B189 Many popular Internet applications or M2M applications have short burst characteristics and data are delivered through traffic channel in an inefficient way. 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
