Parlay / OSA 
From Standards to Reality

Parlay will enable rapid and cost-effective delivery of services
based on telecommunications networks, and will be an essential part
of the 3G future.

We live in an exciting time. 3G networks are taking off, and as
greater bandwidth and communication speeds become available, people
are seeking new means by which to increase their interaction
potential. Newer and more exciting services are being developed to
drive more revenues and to enhance end-user experiences. New
technologies are being designed and implemented to supplement and
leverage the new capabilities being built into core networks.

Parlay/OSA: From Standards to Reality is an accessible
primer on network ecosystems and operations today, discussing the
need for Parlay, the details of standards, aspects of network
evolution and support for legacy systems, and advanced topics from
an implementation perspective. The authors examine the
potential of the Parlay/OSA (Open Service Access) solution from a
number of points of view: business need, service development and
service deployment.

Parlay/OSA: From Standards to Reality:

* Provides a comprehensive account and examination of the Parlay
technology.

* Covers standards capabilities and directions, and the twelve
Service Capability Features, including call control, mobility
management, data session control, generic messaging service and
content based charging and policy management.

* Addresses architectural alternatives and advanced architecture
patterns.

* Provides use cases, architecture, deployment scenarios and
advanced topics for further reading.

This invaluable resource will provide product managers, software
developers, application developers, network architects and
engineers, as well as advanced students and researchers in academia
and industry with an in-depth understanding of Parlay.
