The intent of this document is to evaluate the aspects of Machine-to-Machine (M2M) communications that are required to ensure that cdma2000?1 network infrastructure is a viable communication network option for the M2M applications@ including: ? Identify M2M service functionalities that capture the fundamentals of M2M communications and possible M2M applications. ?Identify applicable M2M communications use cases and characteristics to ensure that they are the basis for the evaluated network enhancements through out this study. ? Identify the list of potential requirements needed to enable machine type communications on cdma2000 networks based on the identified M2M service functionalities. ? Evaluate the impact of the anticipated large number of M2M devices and how to minimize this impact on the cdma2000 networks (e.g.@ a clear definition of M2M Group Based communications and its usage). ? Identify possible enhancements that would help in providing cdma2000 network operators with lower operational complexities when offering machine-type communication services. ? Optimize network operations to minimize the impact on device battery power usage. This study of M2M Communication is targeting the enablement of machine type data communication services and M2M applications on cdma2000 networks. 1cdma2000? is the trademark for the technical nomenclature for certain specifications and standards of the Organizational Partners (OPs) of 3GPP2.
