A case study of an real-world application that is based on Parlay.

This is a location-based application which is designed for a small business. (A bakery)

The application is based on Microsoft’s MapPoint Location Server

The MapPoint Location Server in turn is built on Sprint’s Business Mobility Framework, which uses the Parlay-X Web Services API.

Specification


www.parlay.org


The foundation of Parlay’s success is the Parlay Specifications – the technical documents that define the Parlay APIs for application developers

These specifications have been through a series of revisions over the last six years– Parlay versions 1.0, 2.0, 2.1, 2.2, 3.0, 3.1, 3.2, 3.3, 4.0, 4.1,

4.2, 5.0 The Parlay Specifications include feedback from initial

Parlay R&D, and from product implementations. The Parlay specifications expanded into new areas such

as Web Services and simplified high level APIs such as Parlay-X

www.parlay.org


Once the Parlay specifications are published, they form the basis of development for products– Gateways, application servers, applications, tools

The initial set of Parlay products released in the 2000-02 period supported Parlay 2.1

Parlay products then evolved to support Parlay version 3.x, and Parlay 4.x

Products were then created to implement Parlay Web Services and Parlay-X. – This process was much faster than the original development cycle,

probably as web services technology was widely supported in the IT industry.

Supporting and enabling products are now available,– e.g, development and test tools, developer programs

The Parlay Group works closely with the rest of the industry: there are liaisons with ETSI, PayCircle, OMG and the Java Community and now OMA.

The Parlay/OSA specifications are co-developed by ETSI, 3GPP CN5 and the Parlay Group in the Joint API Working Group

The Parlay/OSA specifications are co-published by ETSI and the Parlay Group

EURESCOM P1110 consortium spent 2 years evaluating the Parlay/OSA specifications and has provided excellent feedback, and published their experiences

ETSI’s Parlay/OSA Plugtests in 2003, 2004 and 2005 demonstrated multi-vendor interoperability. MSF GMI 2004 in Oct 2004, used Parlay interfaces.

Lessons Learned

Parlay Group stand at CommunicAsia 2003, Marc LeClerc (Ericsson)


www.parlay.org

Lessons Learned - 1

The adoption of any new technology takes longer that you think when you first start out– The first Parlay specification dates from 1998.– Parlay prototypes demonstrated in Nov 1998.– Developing products takes additional time– Operator trials take 12-24 months

It is several years before you see standard or technology adoption and deployment


www.parlay.org

Lessons Learned - 2

The industry is changing– Tier 1 telecom operators, and the major Telecom

and IT Vendors still get involved in the creation of standards.

– Most Tier 2 and Tier 3 operators do not have internal R&D groups. They are looking for solutions they can implement immediately.

– Many start-up product companies implement standards that are available, but do not participate in the creation of standards.


www.parlay.org

Lessons Learned - 3

Creating the technology and standardizing it is necessary, but not sufficient, to ensure success– Implementation experience is important. – Feeding lessons from product implementors back into the

standards process improves the quality.– Managing backwards compatibility– Case studies demonstrate how operators are using

technology and standards. These help operators understand how to apply the new technology/standard.

One of the reasons that the Parlay Group has focused effort on marketing and evangalization


www.parlay.org

Lessons Learned - 4

Technology will be used in unanticipated ways:– The original intent of Parlay was to provide an alternative

to the use of the SS7 ISUP interface for managing calls by creating an API

• e.g. call centre applications could use Parlay from outside the network.

– Today there are two ‘clusters’ of Parlay usage.• The Parlay/OSA interface is embedded in products within the

network to simplify service creation, e.g IN SCPs• The Parlay-X Web Services interface is provided to enterprise

and internet customers, e.g. Web Services Gateways


www.parlay.org

Lessons Learned - 5

The environment is becoming more complex The creation of new standards must deal with a

more complex environment than in the past.– 3GPP, 3GPP2, ETSI, IETF, ITU-T, Java, Liberty, OMA,

OMG, Parlay, W3C, WS-* The challenge is to co-operate with other groups,

while still making progress “Re-use, don’t re-invent” Different IPR policies can slow down co-operation


www.parlay.org

Summary

Standards are important ! Don’t expect success overnight. If we as an industry can co-operate on the creation of key

standards it reduces development costs .. … and gives operators much greater freedom of choice when

it comes to implementation This requires changes in the way that standards are created

– Much greater emphasis on feedback from implementations– Much better understanding of how the standards are used by

developers and operators– Communicating with the key stakeholders, especially operators,

about how to use the standards and technology.
