3 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 Mobile Service Provider Aggregation network Edge Node Internet Service Provider Residential Gateway Application Service Provider

4 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, …)

7 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. Sprint White paper Value of a network is exponential related to the number of users

8 Today's broadband situation
Subscriptions tied to household Desktop for Internet Laptop with WLAN Triple play Data Voice Video DSL, Cable, Fiber

9 Coming soon - Portable & Personalized Any service, anywhere, anytime

10 Convergence types Devices Operators Services
Access technologies in the devices Multimedia capabilities Operators Access provider: fixed + mobile Content + access provider Services Same environment

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

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

13 Minimal or not perceptible
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 Movement of user or end device Session (and Service) Loss of data Handover Nomadism Discrete Terminated Not applicable Not possible Session Continuity Continuous Possible break/resume (continuous session) Perceptible Optionally Continuous Mobility Minimal or not perceptible Handover/ Seamless Handover

15 Use Case 1: Part #1 Nomadism with video call
Access Access network network RGW RGW S ettop box Photo viewer Computer Television Computer Videophone Home of Jose's mother Jose's home 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

16 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

17 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

20 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.

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

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.

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

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
