MUSE is a European consortium funded by EC as part of 6th Framework Programme IST
• Strategic objective: “Broadband for All”
What is MUSE ?
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• Standards contributions (DSLF, ETSI, ITU-T, …)

McGuire’s Law (Law of Mobility)
> The value of a product increasewith mobility.
> The cost of adding mobility has come down due to Moore’s law and Metacalfe’s law.
Sprint White paper
Value of a network is exponential related to the number of users
Computer process power will be doubled every 18 month.

Convergence types
> Devices• Access technologies in the devices• Multimedia capabilities
> Operators• Access provider: fixed + mobile• Content + access provider
> Services• Same environment
Muse Summer School, July 2007, BudapestIntroduction to the MUSE FMC network architecture (11)
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
Muse Summer School, July 2007, BudapestIntroduction to the MUSE FMC network architecture (12)
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

Use Case 1: Part #1 Nomadism with video call
Use Case Description
1. Jose starts his parents PC and access the Web portal of this SP, authenticates himself and gets nomadic services.
2. 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

Use Case 1: Part #2 Nomadism with IPTV service upgrade
Use Case Description
4. 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
5. 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.
6. During this time, Manolo’s girlfriend who is not fond of football, could watch another TV program

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. Since bandwidth is more expensive on this network, Bob decides to save money and only keeps the audio channel active.
3. 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

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.
Budapest University of Technology and Economics
Muse Summer School, July 2007, BudapestIntroduction to the MUSE FMC network architecture (21)
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
Budapest University of Technology and Economics
Muse Summer School, July 2007, BudapestIntroduction to the MUSE FMC network architecture (22)
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. ROAMING
> Digital Rights Management may impose several constraints for nomadic services.
Budapest University of Technology and Economics
Muse Summer School, July 2007, BudapestIntroduction to the MUSE FMC network architecture (23)
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. FIREWALL
Budapest University of Technology and Economics
Muse Summer School, July 2007, BudapestIntroduction to the MUSE FMC network architecture (24)
Impact of Use Cases, Requirements 3
> Location of the user must be known by the network. EMERGENCY CALL, location based services
> The network should support SESSION CONTINUITY.
> Charging/billing record may be adjusted depending on the type of access and the bandwidth used.
> If service environment supports, a user may use the same service from multiple different locations simultaneously. Multiple access to the same service

T-Online, DataNet, UPC, TVNET etc. in Hungary
> Application Service Provider:• Provides application services to users• SLA with Packager• User credentials, service parameters to Packager on service
activation, management and usage• For instance a VoD service

Muse Summer School, July 2007, BudapestIntroduction to the MUSE FMC network architecture (28)
Actors and roles in the architecture 3
> Connectivity Provider:• Initial signaling for setting up connections (authentication, IP
address allocation)• Policy Decision Point, QoS verification with the SLA• Signaling for end-to-end QoS provisioning
> Network Access Provider• Access network connections• Management of residential gateways and user devices• Admission control and resource management• Operator who owns access infrastructure, like T-Com or UPC in
Hungary
