Core network aspects 1

6.2.1 End users' perspective

• Converged services that function consistently independent of the access technology or terminal
device being used with associated, reduced complexity of telecommunications operation and
subscription.
• Convenient access to and usage of a wide range of services of multiple service providers through
technology that enables easy configuration, allowing an end user to obtain only one bill if so desired
by this end user, even when multiple service providers are involved.

• Seamless service experiences, whenever desired and wherever the end user may be, limited only by
the capabilities of the access technology and the terminal device being used, and with the
expectation that the end user will have access to multiple terminal devices with different ranges of
capabilities.
6.2.2 Service providers' perspective
• Ability to offer a wide range of services.

• Simplified network deployment and operation through the ability to offer access and terminal
device independent services, as opposed to having to provide multiple access-specific and terminal
device-specific instances of the same service.
• Ability to reuse the fixed-line assets from traditional fixed service providers and mixed service
providers in an FMC context.
• Ability to provide better coverage and QoS to end users compared to traditional mobile service
providers in an FMC context.

7 Fundamental characteristics of FMC
The following points describe the fundamental characteristics of FMC:
• Consistency of user experience is provided through a generic service delivery environment, which
satisfies the needs of the fixed network and of the mobile network. The user is able to obtain services
in a consistent manner as allowed by the connectivity and terminal device capabilities. Services are
offered in accordance with FMC capabilities. For example, an ongoing call could be downgraded for
some reasons, such as change of access technology or terminal device capability. A video
communication may be downgraded to a voice communication when the user migrates to mobile-
only coverage where the access technology is not able to support it.
• Subscriptions and service provisioning are access-technology agnostic but the service stratum may
be aware of both the access and terminal device capabilities involved in a communication instance.
Services are supported in all existing and emerging fixed and mobile access technologies where
possible and subject to user preferences. Service registration, triggering and execution adapt to
network and terminal device capabilities. The user's availability, reachability, and the terminal
device's capabilities are perceptible to network functions, and as needed to services and
applications, including those provided by a third party; assuming that
FMC respects
– the user's privacy and privacy-sensitive data (e.g., address book, preferences, presence settings,
billing/payment settings and other security settings) contained in the user's profile,
– the user's personal preferences (e.g., availability, reachability), and
– the terminal's device capabilities;
and adequately protects this information
– against loss of privacy and loss of confidentiality,

– against unauthorized access, and
– against unauthorized manipulation;
during storage and/or during communication within and beyond a service provider's domain.
