Next/New generation networks, internetworking

• Internetworking may be inspected from
  different points of view
• - technically considering the
  interoperability between networks and integration
  of
• networks
• - development ot the networks of the
  operator the integrity of the network technology
  
• to reduce operation and maintenance costs
• - the service offering of the operator
• - integration of the it operations of an
  enterpise
• - end user (enterprise, private person)
  personalization of services, services
• trasferability, ondependence of terminals

Internetworking
This presentation introduces developing of
technologies and networks towards so called all
IP network, which is also in this presentation
identified as a most probable realizations for
the next generation networks. In the followin
two figures first the prsent situation of
networks will be presented and then one scenario
of the network of next generation. It is
worth noting that even in the second gigure the
telecommunications network is not expected to be
one big entity but a network of networks, which
has one common nominator IP technology. The
time to get to all IP networks, is long, as
usually in telecommmunications. This is because
of the huge size of the networks and that there
have been made huge investments in the networks
and it is not economically possible or even
feasible to replace them in a short term if the
price of services is wanted to be such that end
user are willing to use them.

Internet in mobile environment

• WAP
• iMode (Japan)
• GPRS
• UMTS
• MExE Java programs in the terminal
• SIM Application Toolkit (SAT) services

SIP based technologies in service
control and creation

• IN platform with SIP functionality (SIP Plug in)
• Developing SIP based applications and services,
• PINT and SPIRITS
• -    evaluation of these technologies
  from the service/network operator
• point of view
• -    study of web service technologies as
  a means of distributing service
• control in the networkSOAP, WDSL,
  UDDI
• -    demonstrations of these items in the
  telecommunications research
• network and
• - analysis of them from network,
  service/network operator,
• service subscriber end service user

PINT/SPIRITS Architecture (1/2)

• PINT
• IETF specification (RFC 2458, RFC 2848)
• PINT is used for invoking telephone services from
  the IP network
• Target services
• Click-To-Dial
• Request to Fax Content
• Request to Speak/Send/Play Content

IP Network
Internet Service Provider
Telecom operator

PINT/SPIRITS Architecture (2/2)

• SPIRITS
• IETF specification (RFC 3136, RFC 3298,
  draft-ietf-spirits-protocol-04)
• SPIRITS is used for invoking IP based services
  from telephone network
• Target services
• -Internet Call Waiting
• Internet Caller-ID Delivery
• Internet Call Forwarding

IP Network
SCP SPIRITS Client

PINT/SPIRITS main features

• PINT and SPIRITS are enhancements for
• SIP and SDP
• Support for IN Detection Points (Trigger,
• Event)
• REGISTER used to requesting notifications,
• relating to TDPs
• INVITE for notifying fired TDP
• SUBSCRIBE for monitoring requested
• call and notifications from EDP triggers
• NOTIFY for notifying fired EDP trigger
• and change in the session state
• UNSUBSCRIBE for ending the
• monitoring session
• Use of XML payload defined by the
• standard
• Can also handle Parlay events

Example SPIRITS based VPN Service

• The following slides gives an example of a
  SPIRITS solution, which has been developed in
  cooperation with HP and Satakunta Polytechnic
  mainly as internships at HP labs Grenoble
• The idea of this solution is to distribute a part
  of the service control in the SPIRITS Server in
  IP network
• The VPN service subscriber has an access to this
  server and is able to manage her/his service
  using Graphical User Interface
• define the VPN group, modify the group etc.
