CPqD Background

• Intelligent Networks first deployment in Brazil
  in mid-90s.
• Service Development Laboratory
• Service modeling specification
• Service development
• Tests
• National Standard ETSI CS1-based INAP-BR.

CPqD Background

• SW-CMM (Capability Maturity Model for Software)
  level 2 certified.
• CMMi (Capability Maturity Model Integration)
  level 3 is being pursued by mid-2006.
• GSAM (Multimedia Services and Applications
  Management) uses RUP (Rational Unified Process)
  for software development.

Software Development for NGN (SIP)

• CPqD has been developing applications using SIP
• APIs since the beginning of 2002.
• Since 2002, CPqD has developed several
  applications like
• CPqD - Freephone
• CPqD EasyVoIP

10
Software Development for NGN (SIP)

• General Comments
• The API requires knowledge of the specification
  of the SIP protocol to develop a service.
• The SIP architecture provides only one interface
  to the telecommunications network. It doesnt
  provide a standard interface to all
  telecommunications network simultaneously.
• The SIP architecture provides a poor interface
  with each network elements. It requires to
  increment this interface which results in a
  dependency of the network elements suppliers.

Software Development for NGN (Parlay)

• CPqD has been studying the Parlay concepts since
  2001.
• Analysis and demo tests of application servers
  and parlay gateway simulators from different
  vendors were performed, with the idea of building
  a development and test laboratory.
• In 2003, CPqD deployed its first Parlay
  application for use in a trial for one of the
  most important fixed telecom operators in Brazil.

14
Software Development for NGN (Parlay)

• The application's goal was
• To test the gateway implementation of the
  MultiPartyCallControl APIs through a prototype
  built by CPqD.
• The main features of the application developed to
  test the MPCC (MultiPartyCallControl) API were
• The calls were created and controlled through a
  web interface
• Any number of additional call legs could be
  created
• The call could be scheduled
• Simultaneous calls could be made once one
  answers, the others would be cancelled.

Software Development for NGN (Parlay)

• Learned Lessons
• The trial involved three different players
• The Parlay Gateway supplier
• The Application Server supplier
• The Application developer
• The interaction between those players was
  productive and smooth.
• The application, tested by means of a Parlay
  Gateway simulator, had the same behavior in the
  real environment, with the Parlay Gateway being
  from a different vendor than that of the
  simulator.
• The same application can be used in all platforms
  that support the MultiPartyCallControl API.
• The Parlay APIs became this complex application
  development easier and faster

19
Experience in Chile
Software Development for NGN (Parlay)

• CPqD worked together with a partner to create an
  application for a trial in a Chilean fixed and
  mobile operator.
• Application Description
• A voice conferencing was developed, using the
  service creation environment from CPqDs partner.
• The application had several features for
  conferencing, such as a web interface for
  administration, moderation and notification by
  e-mail.
• Results
• The application was installed and running in less
  than one week.
• Integration between gateway and application
  server ocurred smoothly.
• This application had a high degree of complexity,
  but even so it was developed in a relatively
  short period of time (2 months)

23
Conclusions

• The Parlay architecture provides an interface to
  all telecommunications network.
• This interface allows to create a standard API
  for services development.
• The simplicity of this standard results in its
  easy dissemination.
