Roke Manor Research
 RMR is a Siemens UK R&D operating business
 Siemens is in the top 4 for R&D investment - €5.3bn in 2003
 RMR undertakes R&D in fixed and mobile communications,
sensors and information technology
 Active in standardisation relating to FMC topics within a number
of organisations including ETSI,
3GPP, IEEE and IETF
 Experienced in developing standards
compliant systems in both fixed and
mobile communications
 RMR is a contract R&D house that undertakes
work both for Siemens and for a wide range of third party
organisations around the world

Fixed Mobile Convergence
 Right now we have two voice/data worlds – Fixed
wireline and Mobile wireless
 We also have Wi-Fi (and very soon WiMAX and
Korea is developing WiBro) which are generally seen
as being a kind of wireless fixed solution but often
operated by mobile operators (or their partners)
 But… Wi-Fi is beginning to adopt SIM-based authentication
(eg EAP-SIM) making it look a little more like mobile
 FMC aims to provide a single back-end infrastructure
supporting all fixed and mobile users,
potentially with single sign-on access
The best way to predict the future is to invent it.

Why FMC?
 FMC offers:




Tariffing
Ubiquity (any network access)
Ease of use (single sign-in, common user experience)
Enhanced mediated services – often peer to peer and
making use of presence (& possibly also location) info:




Multimedia instant messaging (IM)
Presence-based games
Cooperative content sharing & editing
IM for interaction with knowledge “agents”
Prediction is very difficult, especially about the future.

User Motivations for FMC
 Single device – single contact number
 Personal rather than shared device
 Traditional home phones are family phones
 No personal address book
 No personal SMS/MMS messaging history
 Traditional mobiles are personal phones
 Personal address book & SMS history
 Personalisation – ringtones, wallpaper, customised shortcuts
 Consistent user experience across cellular, fixed-line
and hot-spot access
 Cheaper tariffing at office and home
 Presence-based applications and services
 Access to higher data-rates at office and home

Operator Motivations for FMC
 Single back-end infrastructure giving cost and
support savings
 Value-added services can be seamlessly delivered
over a wide range of bearers with flexible tariffing
including post-paid contract
 All end-user devices strongly authenticated
 VoIP traffic can be effectively tariffed
 FMC can hide details of one operator’s
infrastructure from its interconnected
neighbours
Where a calculator on the ENIAC is equipped with 18,000 vacuum tubes and
weighs 30 tons, computers in the future may have only 1,000 vacuum tubes
and perhaps weigh 1.5 tons.

Progress in Standardisation
 Standards led
ETSI, 3GPP,
ITU-T, IEEE,
IETF
 Market led
 Some people in the market-place cannot wait for
standardisation
eg Skype & other new entrants
The future, according to some scientists, will be exactly like the past, only far
more expensive.

Fixed Mobile Convergence Alliance
(FMCA)
 FMC handset technologies favoured by the
Fixed Mobile Convergence Alliance (FMCA):
 Bluetooth CTP (cordless telephony profile)
 Wi-Fi SIP (VoIP using SIP signalling)
 Wi-Fi UMA (GSM tunnelled over
Wi-Fi)
Half our life is spent trying to find something to do with the time we have rushed
through life trying to save.
Will Rogers (1879 - 1935), New York TImes, Apr. 29, 1930

UMA - Unlicenced Mobile Access
 FMC by tunnelling GSM over IP
(via Wi-Fi or Bluetooth)
 UMA (Unlicenced Mobile Access) –
eg BT Bluephone “Fusion”, offering
roaming of GSM onto fixed line
 UMA is now 3GPP work item
"Generic Access to A/Gb interfaces“,
and is now part of 3GPP Release 6+
activity
I never think of the future - it comes soon enough.

3GPP – IP Multimedia Subsystem
 3GPP Rel 5 – IMS for non-real-time services and near
real-time services
 3GPP Rel 6 – IMS for real-time services
 Uses Session Initiation Protocol (SIP)
 IMS infrastructure provides a set of SIP
application servers, subscriber databases
(HSS) and gateways to enable a variety
of integrated voice and data services
 IMS was developed for mobile rather than fixed…
 …3GPP has now added new work items for network
independence of IMS – e.g. over Wi-Fi as well as
3G/GPRS

ETSI TISPAN
 “Telecoms & Internet converged Services & Protocols for
Advanced Networks“
 Fixed line transition from circuit-switched to packet-switched
voice services
 Fixed network service aspects,
architectural aspects, protocol
aspects, Quality of Service (QoS) studies,
security related studies & mobility aspects
within fixed networks
 Encompasses ETSI FMC standardisation activity
 Recent agreement that TISPAN will use relevant 3GPP (IMS)
docs to realise FMC
 ETSI TISPAN & 3GPP IMS seen as the “official” route to FMC in
Europe

Some relevant IETF activities
 VOIPPEER (for VoIP operator interconnect)
 Subject of recent meetings to establish new
IETF Working Group
 Focus on peering arrangements for VoIP
operators to interconnect over the Internet
 cf GSMA GRX (GPRS Roaming Exchange)
but over the Internet rather than through
private links
 ENUM to assist call routing and number translation
 Session Initiation Protocol (SIP) -related activities
 From a central role in IMS for large operators…
 … to enabling DIY interconnect for very small VoIP operators

EU Framework Programme 6




Wireless World Initiative (WWI)
Projects funded by EU under FP6
Focus is on systems beyond 3G
Projects cover:
 New air interface
 Network infrastructure, includes work on
convergence between different operator
business environments – such as dynamic roaming
 Services and applications
 The FMC world will increasingly require large
numbers of roaming agreements between “operators”
of all sizes, including relationships with home or
business networks

Terminals
 FMC-type terminals have been slow to
appear but there are examples:
 BT Bluephone “Fusion” service
 KT One Phone service
 Siemens M34 Gigaset USB Adapter
allows home DECT phone traffic to be
routed via a PC out as VoIP traffic using
Skype or SIP
 dualphone.net cordless DECT handset
basestation connects via USB to a PC running
Skype, DECT terminal LCD display indicates
online “presence” status of Skype buddies

FMC client software
 IMS FMC clients have been slow to appear
 At present, FMC-like client software typically:
 Mainly Open Mobile Alliance (OMA)
Wireless Village clients on phones
 Mainly AIM
(also Yahoo, MSN Messenger, Jabber etc)
or Skype on PDAs and PCs
 Siemens OpenScape client on PCs
 + some use of SIP-based VoIP eg sipgate, esp. in
Europe but firewall issues have slowed uptake

Infrastructure
 IMS infrastructure now being offered to
Mobile and Fixed Network Operators
 Siemens IMS already being adopted
in both fixed and mobile worlds
 SIP-based IMS infrastructure makes
it easy to develop enhanced services
running on SIP application servers
It would appear that we have reached the limits of what it is possible to achieve
with computer technology, although one should be careful with such statements,
as they tend to sound pretty silly in 5 years. John Von Neumann (ca. 1949)

The future
 Terminals are becoming ever more sophisticated
 User interfaces for small form-factor devices are becoming
more effective
 Increasingly people expect to be able
to access more than just voice from
their phone
 Increasingly people expect to be able
to access more than just data from their PC or PDA
 The technical barriers to FMC have been pretty much
resolved, it is now up to the operators and consumers…
Any sufficiently advanced technology is indistinguishable from magic.
