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. Network Service Provider Network Access Provider Access Node Customer Premises First Mile MobileService Provider Aggregation network Edge Node Internet Service Provider Residential Gateway Application Service Provider
What is MUSE ? • MUSE is a European consortium funded by EC as part of 6th 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 • Standards contributions (DSLF, ETSI, ITU-T, …) http://www.ist-muse.eu

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. Computer process power will be doubled every 18 month. • Sprint White paper Value of a network is exponential related to the number of users
DSL, Cable, Fiber Today's broadband situation Subscriptions tied to household • Desktop for Internet • Laptop with WLAN • Triple play • Data • Voice • Video
Coming soon - Portable & PersonalizedAny service, anywhere, anytime
Convergence types • Devices • Access technologies in the devices • Multimedia capabilities • Operators • Access provider: fixed + mobile • Content + access provider • Services • Same environment
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
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
Mobility (taxonomy) • Nomadism • The ability of the user to change his network access point on moving • Session continuity • The ability of a user or terminal to change the network access point while maintaining the ongoing session • Continuous mobility • The ability of a mobile user/terminal/network to change location while media streams are active • Roaming • Handover

Use Case 1: Part #1 Nomadism with video call Access Access network network RGW RGW S ettop box Photo viewer Videophone Computer Computer Television Jose's home Home of Jose's mother • Use Case Description • 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 • 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 • 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
Use Case 2: Session Continuity with conversational services (Voice and Video over IP) • Use Case Description • Bob’s phone gets out of the reach of the wireless home network, the phone is connected to a WIMAX (or UMTS) base station. • 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
Other Use Cases • e-Health • Medical consultant (Eva) visits the patients in their homes • Connects to the medical VPN • Using public / shared private wireless access points

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
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.
Impact of Use Cases, Requirements 2 • Media adaptationmay 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
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

Actors and roles in the architecture 1 • Customer: • Starts a service session on a device after authenticated • Has a contract to one or more Packagers with a user profile • May have a home network possibly with public access (public WLAN access point) • Packager: • Maintains user’s policy profile and SLA • Contract delivery to Users (including profile, equipment, Helpdesk etc.) • Service Level Agreements with Connectivity Provider, different service providers, other Packagers • Accounting and billing • IMS
Actors and roles in the architecture 2 • Network Service Provider: • Provides the function for Internet services • SLA with Packager • Credentials to Connectivity Provider • Network access parameters to Packager • ~ an ISP in the current terminology without address allocation, like 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
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 • Regional Network Provider • Interconnects NAPs and NSPs
