their privacy, multimedia preferences,
permissions and identity; the freedom
to control their availability, location,
presence and call-handling; and the
freedom to control opt-ins, opt-outs,
notifications and memberships, be
they contacts, buddies or groups.
Privacy management is essential
to promoting user confidence when
adopting privacy-sensitive services
such as advertising, Location-Based
Services (LBS), and personalized
broadband services. In a public opinion
poll by Forrester Research, 43 percent
of respondents felt that LBS would
threaten their privacy. In some jurisdictions
such as the US, there are even regulations
requiring that LBS demonstrate compliance,
the FCC Customer Proprietary Network
Information (CPNI) rules for instance.

Clearly, FMC brings with it
significant benefits, chief among
them the ability to supply communication
services ubiquitously while supporting
nomadic and mobile capabilities. |
The
core of personalized service
delivery will be the ability
to collect, analyze, and use
information about subscribers
and their preferences. Unfortunately,
the Internet experience demonstrated
that personal data is a valuable
asset that can be used incorrectly
or fraudulently, and therefore
subscribers are reluctant to
give it away for reasons ranging
from simple inconvenience (i.e.
unsolicited ad messages or spam)
to real threats such as identity
theft. Thus the GUP, HLR, HSS
constructs require augmentation

| The role of GUP and HSS standards
Numerous industry initiatives like Microsoft
Passport and Liberty Alliance were started
to address the issue of user profile data
management. A telecom-based initiative 3GPP
Generic User Profile (GUP) aims to aggregate
user profile information relevant to network
operators. The HSS (Home Subscriber Server),
or User Profile Server Function (UPSF), is
the master user database that supports the
IMS network entities actually handling the
calls/sessions. Similar to the GSM Home Location
Register (HLR), the HSS contains subscription-related
information (including the IMPU, IMPI, IMSI,
and MSISDN), performs authentication and
authorization of the user, and can provide
information about the physical location of
user.
While HLRs enabled the mobility of services
outside the home network, services are generally
restricted to a fair degree within visited
networks. HSS improved on this by enabling
most home services to be available in visited
networks. However, a shortcoming of GUP,
HLR, and HSS is that they do not provide
accommodation for user preferences, privacy,
or context sensitive services.

securely

management aspects.
Policy Management
for FMC Networks
Consistent and predictable
Quality of Service (QoS) levels will also
form a crucial part of the end-user experience
across access technologies. It will therefore
be important to regulate and guarantee
QoS levels on a per-service and per-subscriber
basis. In particular, given the varying
nature of next-generation media services,
the ‘best effort’ delivery
of services will almost guarantee inferior
service levels irrespective of the access
technology used, resulting in dissatisfied
subscribers. It will therefore be important
to both regulate bandwidth in a manner
that allows carriers to mitigate costly
capacity build-outs for low-value traffic,
and to provide a means to optimize the
generation and delivery of content and
services in a manner that meets the contextual
requirements (e.g. fixed vs. wireless)
as well as the preferences of the subscriber
as stored in a subscriber repository.
