Delivering Fixed Mobile Convergence (FMC) with IP
Multimedia Subsystem (IMS)
Dr. Mazlan Abbas Wireless Communica5ons Cluster
MIMOS Berhad 2008
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
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
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
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!
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
New and exci5ng applica5ons?
• Personal mobility • Terminal mobility
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.
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
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?
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?
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

Role of MIMOS
• To host and manage the opera5on/maintenance of the CoE • Facilitate and interface with developers or content providers
– To provide par5cipants with SDK as to aid their developments – To provide sample applica5ons on service crea5on, programming
advice and troubleshoo5ng – To define and provide test plan – To manage the project from implementa5on, tes5ng and
commercializa5on • To promote local developer’s contents/services
– University, Companies or Individual (through funding sources)
