What is the objective of the research in MUSE ?
Multi service access network from fixed operator’s point of view
that provides secure connectivity
between end-user terminals and edge nodes in an open, multi-provider environment
at a low cost for every European citizen.
Access Node First Mile
Network Service Provider Customer Premises
Aggregation network Edge Node
Mobile Service Provider Internet Service Provider
Residential Gateway
Network Access Provider Application Service Provider

What is MUSE ?
MUSE is a European consortium funded by EC as part of 6
th
Framework Programme IST
• Strategic objective: “Broadband for All”
Co-operative research of operators, vendors and academia
• Studies are driven by requirements from European operators • Addresses medium and long term commercialisation
Output
• • • Research reports Proof of concept in lab prototypes http://www.ist-muse.eu
Standards contributions (DSLF, ETSI, ITU T, …) Introduction to the MUSE FMC network architecture (4)

McGuire’s Law (Law of Mobility)
> > The value of a product increase with mobility.
The cost of adding mobility has come down due to Moore’s law and Metacalfe’s law.
Computer process power will be doubled every 18 month.
Introduction to the MUSE FMC network architecture (7)
Value of a network is exponential related to the number of users

Opportunity with FMC/multi-access
> Multiple access networks used as a competitive advantage > Subscriber offerings • • Quadruple-play bundling (data, voice, video + mobility) New differentiating nomadic services
“Whenever, where ever”
> Synergies • • Maximize usage of same infrastructure for all services Reuse mobile investments for fixed broadband and vice versa Introduction to the MUSE FMC network architecture (11)
Muse Summer School, July 2007, Budapest
Challenges with multi-access
> Access to subscribed services at any location • Personalization of network services, individuals rather than household • • Common subscriber management Ensure service delivery over any access type > Differentiate and control subscriber traffic • • • Introduction of new unique nomadic services Service aware handling of subscriber traffic (QoS) Flexible charging based on service and access type > Multi-standard environment • • DSLF, 3GPP, IEEE, WiMAX, ETSI TISPAN Terminal > Mobility • • • Hand-over between access technologies Session continuity Roaming Introduction to the MUSE FMC network architecture (12)

Use Case 1: Part #1 Nomadism with video call Access network Access network RGW RGW Settop box Photo viewer Computer Television
Home of Jose's mother
Use Case Description 1.
2.
Computer Videophone
Jose's home
Jose starts his parents PC and access the Web portal of this SP, authenticates himself and gets nomadic services.
He then initiates a video over IP call from the PC to his home video capable multimedia phone to let his wife know his whereabouts 3.
Next he will access his media-center (can be in his CPN or at another location), to show the pictures from his daughter’s last birthday, and shows it on the TV screen at his parents home Introduction to the MUSE FMC network architecture (15)

Use Case 1: Part #2 Nomadism with IPTV service upgrade Access Network Access Network RGW Settop box 5 8 7 * 8 # 9 6 Settop box RGW Settop box Television Televisio
Manolo's home
Use Case Description
José's home
Television 4.

6.
After he reached his home an important match started. While watching he receives a call from his friend Manolo asking José to come to his house to watch the match together When José arrives in Manolo's house he upgrades the TV service using his own subscription to HDTV quality and access the match so that are able to enjoy the match together in HDTV quality. During this time, Manolo’s girlfriend who is not fond of football, could watch another TV program Introduction to the MUSE FMC network architecture (16)

Use Case 2: Session Continuity with conversational services (Voice and Video over IP)
Company's building Bob's home
Access network
Park
Home Gateway 802.11b/g audio + video audio+video Wifi / WiMAX / UMTS audio Use Case Description 1.
Bob’s phone gets out of the reach of the wireless home network, the phone is connected to a WIMAX (or UMTS) base station.
2.
3.
Since bandwidth is more expensive on this network, Bob decides to save money and only keeps the audio channel active.
After reaching his office he transfers the running video call from the mobile terminal (WiMAX, UMTS) to his Notebook connected to a fixed access network Introduction to the MUSE FMC network architecture (17)

End User Requirements on Services
> Convenience and ease of use • Users expect similar interfaces for the services accessed irrespectively of the network in use (fixed or mobile).
> Always best connected • Users expect to always be connected at any time and to the best possible access technology and that irrespectively of where and when – even when on the move.
> Reliability and security • Users expect reliability in all transactions independent of access and connection quality. The users also expect a high level of security from e.g. spam, fraud, viruses, eavesdropping etc.

Nomadic requirements
> Nomadism implies ubiquitous access to subscribed services. This could include: • Access from the primary residence (home).
• Access from a secondary residence (e.g. summer house).
• Access from a neighbour’s or friend’s residence.
• Access from the office.
• Access using public access (e.g. WiFi hot-spot) • Access using the mobile/cellular network.
> Roaming relationship between providers Introduction to the MUSE FMC network architecture (21)

Impact of Use Cases, Requirements 1
> The user should be able to access his/her services from any available network connection.
NOMADISM
> Authentication is based on credentials.
AA
> A nomadic user may connect to other user’s residential network, local policies must be considered.
POLICY
> The user should be allowed to continue his/her services in a different access network.

Impact of Use Cases, Requirements 2
>
Media adaptation
may be necessary when a nomadic user or device changes his connection point and the service quality or access characteristics at the new location are different or the codec used is not more supported. > Network must keep security and privacy for both nomadic and local users.
SECURITY, PRIVACY
> Users and terminals must be addressable at layer 3 in residential networks.
