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

1. Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)   Dr.  Mazlan  Abbas   Wireless  Communica5ons  Cluster   MIMOS  Berhad   2008  

2. 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  

3. 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  

4. 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  

5. How  do  we  start?   •  Must  Break  the  Vicious  Cycle   Where are the users? IMS Telcos / Operators Telcos don’t implement IMS! No testing ground! Devices Users Device Manufacturers No exciting applications! Applications Limited device support! Applications Developers

6. 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  

7. New  and  exci5ng  applica5ons?   •  Personal  mobility   •  Terminal  mobility  

8. 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.    

9. 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

11. 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?  

12. 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?    

13. 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
