Delivering Fixed Mobile Convergence (FMC) with IP Multimedia Subsystem (IMS)
Delivering Fixed MobileConvergence (FMC) with IPMultimedia 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 Where are the IMS users? Telcos don’t Telcos / Operators implement IMS! No testing Devices ground! Users Device No exciting Manufacturers applications! Limited device Applications support! Applications Developers
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

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

Milestones/Schedule 2008 • Q1 – Iden5fy issues on sefng up IMS test-‐bed – Iden5fy requirements, usage scenario of performing service adapta5on, leverage on IPv6 capability • Q2 – Set up and test the IMS network – Develop IMS-‐enabled VoIP applica5on – Design the codec selec5on scheme – Iden5fy por5ng works on IPv6 VoIP into IMS compa5ble applica5on – Develop an IMS-‐enabled VoIP integrated with IPv6 capability, demonstra5ng codec selec5on and device switching – Conduct performance measurement
Milestones/Schedule 2008 • Q3 – Design the network selec5on scheme – Iden5fy por5ng works on IPv6 IPTV into IMS compa5ble applica5on – Develop an IMS-‐enabled IPTV integrated with IPv6 capability, demonstra5ng network selec5on – Conduct performance measurement • Q4 – Showcase IMS-‐enabled VoIP and IPTV applica5on prototype
Tangible Outputs • IMS-‐based VoIP client running on IPv4 and IPv6 • VCC server on IMS • Handover management server on IMS • Informa5on Server (provides network info) • Triggering algorithms • IMS on IPv6 and IPv4 compa5bility and performance study • SIP-‐based versus MIP-‐based connec5on handover study
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)
