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.

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

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.

Value of a network is
exponential related to the
number of users

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

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
•
>
Always best connected
•
>
Users expect similar interfaces for the services accessed
irrespectively of the network in use (fixed or mobile).
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.
Introduction to the MUSE
FMC network architecture (22)
Muse Summer School, July 2007, Budapest
Budapest University of Technology and Economics
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

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
