  • Process Centric Guidance and Tools for Next Generation Network Services API Design

    Internet Multimedia Services Architecture and Application(IMSAA), 2010 IEEE 4th International Conference

    The growth in the number and variety of Network Application Programming Interfaces (APIs) like location, messaging, entertainment, personal storage and computing available to developers today and their rapid evolution has led to increased complexity of use in terms of adoption and keeping up with the incremental changes. Operators thus face an increasing need to roll out new Network Service APIs effectively and seamlessly. Well designed APIs not only make user adoption easier but also increase…

    The growth in the number and variety of Network Application Programming Interfaces (APIs) like location, messaging, entertainment, personal storage and computing available to developers today and their rapid evolution has led to increased complexity of use in terms of adoption and keeping up with the incremental changes. Operators thus face an increasing need to roll out new Network Service APIs effectively and seamlessly. Well designed APIs not only make user adoption easier but also increase the probability that the user of the API will choose the Network Services API over other competing APIs in areas where standards are not available. The success Network Services APIs will to a large extent drive the external business case for Service Delivery Platforms in IMS in terms of ease of creation of new services leveraging operator services and capabilities. There is a lack of process centric guidance targeted at all important stakeholders like architects, designers, testers, the governance bodies and marketing personnel for the design of effective Network Services APIs which can help alignment with initiatives like SOA. This paper attempts to remedy the same by providing process centric and empirically grounded guidance for their creation and usage based on the practitioner engagements with leading operators and provides tools for automation.

  • Realizing the True Service Layer – Transformation of a Network Operator into a Service Provider

    Moriana Group

    SDP-based service deployment is in planning phase or in progress by almost all
    the telecom network operators in the world today. The network operators seem to
    understand the need for a good service layer and have built a vision of transforming
    into service providers. However there still seems to be a lot of disconnects while
    strategizing and implementing the vision. The average period and budget for the
    metamorphosis of network operators into service providers seems to be much…

    SDP-based service deployment is in planning phase or in progress by almost all
    the telecom network operators in the world today. The network operators seem to
    understand the need for a good service layer and have built a vision of transforming
    into service providers. However there still seems to be a lot of disconnects while
    strategizing and implementing the vision. The average period and budget for the
    metamorphosis of network operators into service providers seems to be much more
    than it ought to be. This paper attempts to bring out the key attributes of the evolved
    true service layer that the network operators should strive to achieve in order to
    successfully transform into the “service provider who also owns the network”. It also
    identifies the components or capabilities that need to be developed to realize the true
    service layer.

  • IPTV and VoD services in the context of IMS

    IEEE IMSAA 2007

    IPTV and Video on Demand(VoD) services are
    becoming means for traditional Service Providers to fight back
    against the competition from Cable Companies. Many of the
    large service providers are deploying networks and delivery
    infrastructure to deliver IPTV and VoD on IP based networks.
    At the same time, they are looking at the possibility of migrating
    their traditional PSTN networks towards IMS. Given that the

    IPTV and Video on Demand(VoD) services are
    becoming means for traditional Service Providers to fight back
    against the competition from Cable Companies. Many of the
    large service providers are deploying networks and delivery
    infrastructure to deliver IPTV and VoD on IP based networks.
    At the same time, they are looking at the possibility of migrating
    their traditional PSTN networks towards IMS. Given that the
    two events happening almost at the same time, Service Providers
    will need to consider the possibility that IPTV+VoD services
    could be delivered over IMS network to prevent IPTV+VoD as
    another service capability of an IMS network. This paper
    proposes an architecture for deploying IPTV & VoD as services
    on an IMS based network. It analyzes the short-comings in the
    IMS specifications and steps taken by standards bodies to
    address them.
