Service example: Televoting, cont'

Service example Televoting, cont.

• The service provider offers the service
  subscriber a www based user interface. Using
  this the subsrcriber may choose the service,
  describe the voting to be carried out (how and
  what to vote). He gets also an analyzer to
  follow the results .
• Because both the service subscriber and service
  user has a possibility to use Internet as a part
  of the service event, it is possible to integrate
  other material and other internet based services
  to a part of the service.
• Examples of solutions voting the best player in
  a football match,
• voting a song to be presented in a concert
  etc. In these cases the voting is a part of the
  whole event, the subscriber is the organizer of
  the match/concert. Mobile phone is used for
  voting. Results are displayed in the screen.

Location based services

• The focus of the research is in studying
  standards and implementig solutions based on
  these standards, which cover
• - MLP (Mobile Location Protocol) of OMA/LIF
  in transferring positioning data
• - GML(Geography Markup Language) of OpenGIS
  consortium in positioning
• data coding and
• - WMS and ja WFS specifications (Web Map
  Server and Web Feature
• Server) of OpenGIS in server
  architecture.
• In addition to these also satellite based
  psotioning methods are studied.
• The research environment consists of Ekahau
  Positioning Engine 2.0 WLAN positioning server
  and applications connected to it.
• During the project the following realizations
  have been realized navigator based map service
  and intergration of an MMS distributor and WLAN
  positioning.

Integrating Voice XML and location based services

• During the next study period (2003-2004) these
  two research areas Voice XML and location based
  services will be partly integrated to study and
  develop voice based and voice conrolled location
  based services like tourist guidance and guidance
  for blind people. These services will be
  demonstaretd and tested using the
  telecommunications research network.

Example of televoting

• Predefine telephone number for each televoting
  service.
• Large possibility of choice (max. 50 names)
• Large possibility of predefine digits per name
  (from 01 to 99 )

Which type of music you like? Compose the
number 02647996XX
02647996?

Service example Televoting

• The service has been realized in a PC located in
  the IP network, called
• IP SCP
• The voting is done by using specific telephone
  numbers, which are used as triggers in the
  telephone switch (SSP) . When triggered the SSP
  establishes a signalling connection to the IP
  SCP. In the tephone network the signalling
  protocol (Intelgent Network Application part,
  INAP) is carried in the SS7 signalling network
  to the signalling gateway (SS7/IP gateway), which
  transfers the signalling messages to the payload
  of TCP transport protocol over IP protocol. IP
  network carries the messages to the IP SCP.
• The IP SCP registers the vote and establishes a
  connection to the Intelligent Peripheral
  (including IVR functionality) asking it to mplay
  an announcment telling the voter that her/his
  vote has been registered.
• The service user (voter) may follow in real time
  the progress of voting from the web site
• The vote may be given also sending email. In
  next version also SMS may be used for voting and
  later also MMS.
•  
• All the research areas described above have
  strong synergy with each other and contribute to
  defining and implementing new service
  archtitectures to offer end users easy to use
  services that make use of different networks and
  integrate global and local services seamlessly.
