Definitions
• Service Convergence: From the user’s perspective,
services operate in a sufficiently similar manner (minimal
or no perception of changes when accessing from
different service providers, through different devices or
different access technologies).
• Service Continuity: From the user’s perspective,
services operate in a sufficiently similar manner (minimal
or no perception of changes) as the user moves the active
service between access technologies and devices.
• Service Delivery Platform: An architecture that enables
the rapid development, deployment and integration
(convergence) of broadband, video, wireless and wireline
services. An SDP can support many technologies
including VoIP, Mobile Telephony, IPTV, HSD (High Speed
Data), Online Gaming, etc.

ATIS NGN Framework – Gap Analysis
Assessment of NGN service enablers;
progress of NGN standards development
(GSC11_GTSC4_22)
•
•
•
Service Decoupling - enables services to be defined and delivered
independent of a specific "vertical” network function; enables a flexible
service environment, including third party services
– Gaps: application/end user access to service capabilities, resource
control
Service Transparency - enables services to evolve independent of the
network
– Gaps: service interworking with non-NGN, maintain Internet end-toend transparency (NATs, Firewalls) in NGN
Unified User Profile - enables service capabilities to be accessed from
a range of devices and locations
– Gaps: Web Services, IPTV

What is OSA/Parlay?
Open Service Access (OSA) has been developed as part of the 3GPP specifications in coordination
with ETSI and Parlay (and liaisons with 3GPP2, OMA, and others). The Parlay Group is a multivendor consortium formed to develop open, technology-independent APIs that enable the
development of applications that operate across multiple networking environments.

Applications are independent of underlying
network technologies and can be hosted
inside or outside Network Operator Domain
Parlay defines standardized interfaces as
specifications - Service Capability Features
(SCF)
One or more SCF’s are implemented as
Service Capability Servers (SCS) and are –
provided by Network Vendors as a
Parlay/OSA Gateway
The SCS implementation maps the Parlay
interface to the network protocol/interface

 Provides Uniform, Transparent Access to
Services - Hides Network Complexities
 Provides Centralized, Secure, Controlled
Access to Services
 Faster, Simplified Application Development
(Reduced Costs) using commercial
mainstream programming languages,
software, tools, etc. (Java, C++, XML) –
Converges Telecom/IT Worlds
 Expanded Portfolio of Applications - Opens,
Extends Application Creation to ISVs, ASPs,
and Content Providers (New sources)
 New, Enriched, Personalized Applications

Service Platforms and
Interworking of Services
Work on Convergence
ATIS Packet Technologies and Systems Committee (PTSC)
• PTSC Issue S0044
– Service Continuity Between Access Networks
– Work has just started on an aggressive schedule
– As Next Generation Networks (NGNs) evolve and are
deployed, there will be an increasing need to provide
continuity of service as the subscriber transitions from one
access network to another
– Must have a consistent user perspective
– Service delivery needs to be access independent
– Not Just Voice but Multimedia

ATIS Wireless Technologies and Systems Committee (WTSC)
• WTSC Issue P0012
– Voice Call Continuity (VCC)
• seamless continuity for voice calls that move between the two
types of networks (between cellular networks and non-cellular
networks (e.g., wireless LAN networks))
– Contributions to ongoing work in 3GPP

Summary
 Service convergence is a major focus in the Next
Generation Networks vision
 NGN Service Architecture enables service
transparency across networks and secure access to
new and innovative applications
 NGN service architecture supports converged text,
voice, data, video, and multimedia services
 Work needs to continue to address gaps in standards
required to realize true service interworking
Service Architecture and Interworking standards are evolving to
address the requirements of the NGN vision
