15 Muse Summer School, July 2007, Budapest Introduction to the MUSE FMC network architecture (15) 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 daughters last birthday, and shows it on the TV screen at his parents home RGW Home of Jose's mother Jose's home Access network Computer Photo viewer Television Settop box Access network Videophone

16 Muse Summer School, July 2007, Budapest Introduction to the MUSE FMC network architecture (16) 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, Manolos girlfriend who is not fond of football, could watch another TV program

17 Muse Summer School, July 2007, Budapest Introduction to the MUSE FMC network architecture (17) Use Case 2: Session Continuity with conversational services (Voice and Video over IP) Use Case Description 1.Bobs 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

18 Muse Summer School, July 2007, Budapest Introduction to the MUSE FMC network architecture (18) 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

19 Muse Summer School, July 2007, Budapest Introduction to the MUSE FMC network architecture (19) Topics > MUSE Introduction > FMC Introduction > Use-cases > Requirements > Business Roles > Muse FMC Architecture > Next Sessions

20 Muse Summer School, July 2007, Budapest Introduction to the MUSE FMC network architecture (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 Muse Summer School, July 2007, Budapest Introduction 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 neighbours or friends 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 Muse Summer School, July 2007, Budapest Introduction 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 users 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 Muse Summer School, July 2007, Budapest Introduction 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

24 Muse Summer School, July 2007, Budapest Introduction 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
