%0 Journal Article %T A Novel Scalable Architecture on Android to Cater End-2-End IMS Services to Audio Video Terminals %A Suman Kumar S.P %A Vijay Anand %J International Journal of Next-Generation Networks %D 2010 %I Academy & Industry Research Collaboration Center (AIRCC) %X IP Multimedia Subsystem (IMS) known for its prominent service delivery is paving way forapplications like Video Voice over IP (VVOIP) on handheld devices too. Android, a software platformfrom Google, pioneering in middleware and applications domain of handheld devices does not offersupport for IMS services by design.Motivated by these observations, we present novel scalable architecture to cater IMS basedservices on Android. First, we discuss few related works to investigate and analyze the IMS and the roleof SIP in IMS services. Second, we discuss few characteristics of android architecture and detailconstraints associated with middleware sub-system to cater IMS services. Consequently, we describe theproposed architecture addressing inherent challenges like QoS, Extendibility and Security encounteredwhile offering IMS based services. The architectural framework design reduces time-to-deployment byusing a layered approach encompassing three layers, namely: QoE Engine, Advanced IMS Service Core(A-IMS) and Application Services Engine (ASE). The A-IMS core is responsible to provide End-2-Endefficient service delivery of IMS services like VOIP. We point out the benefits of using the ASE andgeneric media management and control interface (GMMCI) to ensure smooth and swift portability ontodifferent flavors of android. Finally, we conclude by detailing some use-cases of future IMS services likeVideo Sharing/Video Recording in an on-going Video Telephony Call %K Android %K IMS %K Middleware %K Application Framework %K Wireless Network %U http://airccse.org/journal/ijngn/papers/0910ijngn06.pdf
