Agenda  

•  Why  FMC?  •  Why  IMS?  •  How  do  we  start?  •  New  and  exci5ng  applica5ons  •  Research  challenges  •  Values  •  Roadmap  to  deliver  FMC  using  IMS  •  Milestones/Schedule  2008  

Page 3: Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)

Why  FMC?  

•  Wireless  network  +  fixed  network  +  internet  service  crea5on  &  paradigm  à  All  IP  network  

•  Overlay  of  various  networks  à  allows  many  IP-­‐based  apps  to  be  func5onal  on  the  move  

•  As  networks  converged  à  need  for  seamless  connec5vity,  to  access  different  services  regardless  of  loca5on,  terminal  and  network  

Page 4: Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)

Why  IMS?  

•  Operators  need  to  create  new  revenue  streams,  cut  expenditures,  but  extend  their  value  chain  up  to  service  crea5on  

•  Improved  end-­‐user  experiences    •  Standardized  IP  mul5media  environment,  developed  by  ETSI  TISPAN  and  3GPP  

Page 5: Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)

How  do  we  start?  

•  Must  Break  the  Vicious  Cycle  

IMS

Users

Applications

Devices

Telcos don’t implement IMS!

Telcos / Operators

Applications Developers

Device Manufacturers

Where are the users?

No exciting applications!

Limited device support!

No testing ground!

Page 6: Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)

MIMOS  CoE  

•  Set  up  a  testbed  for  applica5on  developers  and  users  to  try  out  new  services  

•  Create  new  and  exci5ng  applica5ons  to  aZract  more  users  

•  Demonstrate  to  both  telcos  and  device  manufacturer  the  importance  of  suppor5ng  IMS  

Page 7: Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)

New  and  exci5ng  applica5ons?  

•  Personal  mobility  •  Terminal  mobility  

Page 8: Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)

Applica5on  (1):  Personal  Mobility  

•  On  his  desktop  (Ethernet),  Bob  sees  that  Jane  is  available  with  the  help  of  the  IMS  presence  server  

•  Bob  decided  to  talk  to  Jane  by  giving  her  a  call  •  Jane  accepted  the  call  and  they  started  talking  •  A`er  a  while,  Bob  feels  thirsty  and  wanted  to  get  a  drink  from  the  Pantry.  

•  So,  Bob  switches  the  call  from  his  desktop  onto  his  PDA  (WiFi),  and  con5nue  talking  to  Jane  on  his  way  to  the  Pantry.    

Page 9: Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)

Applica5on  (2):  Terminal  Mobility  

•  On  his  laptop  at  home,  Bob  starts  an  audio  conference  with  his  business  counterpart  

•  Before  the  mee5ng  finishes,  Bob  rushes  into  a  Taxi  as  to  meet  up  a  customer  at  the  coffee  shop  in  Town  

•  While  on  mobile,  Bob  con5nues  with  his  mee5ng  using  his  laptop

Using  mul5ple  interface  

Page 11: Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)

Research  challenges  (1)  

•  How  is  the  VoIP  quality  maintained  in  event  of  packet  lost  due  to  bad  WiFi  signal?  Network  conges5on?  Search  for  beZer  network?  

•  What  triggers  the  switching  from  one  media/network  to  another?  Applica5on  QoS  drops?  RSSI  drops?  

•  Which  network  to  choose  for  handover?  How  to  discover  the  surrounding  networks?  Mechanism  of  handing  over  the  call?      

•  Who  has  the  control  on  network  selec5on?  Client  or  server?  

Page 12: Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)

Research  challenges  (2)  

•  Reuse  exis5ng  components  from  IPv6  team  – VoIP  and  IPTV  – Probe  on  network  condi5ons  through  IPv6  stack  – Cleverly  tap  onto  Mobile  IPv6?  

•  Mixing  up  technologies  – One  ipv4  client  with  another  ipv6  client?  – Performance  difference  of  connec5on  switching  supported  by  SIP  and  MIP?  Which  one  is  beZer?  When  should  one  be  used?  

 

Page 13: Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)

Values  

•  Provide  solu5ons  and  reference  models  to  FMC  implementa5ons  on  the  following:  – User  experience  on  seamless  connec5vity  – Challenges  to  operators  or  service  providers  – Client  devices  requirements    

•  Solu5ons  are  captured  as  patents  and  papers
