6 Overview of IMT-2020 FMC

6.1 General objectives of IMT-2020 FMC

The following points provide the general objectives for IMT-2020 FMC:
• Seamless service operation from the end user perspective across heterogeneous fixed networks and
mobile networks, subject to any limitations imposed by the characteristics of the particular access
technology being used.

• Seamless service provisioning from the service provider's perspective across heterogeneous fixed
and mobile networks, subject to any limitations imposed by the characteristics of the particular
access technology being used.
• Generalized mobility is supported in FMC (i.e., terminal device mobility, user mobility and session
mobility). For a given scenario, different levels of mobility may be needed.
• Ubiquity of service availability where the end users can enjoy virtually any application, from any
location, on any terminal device subject to any limitations imposed by the characteristics of the
particular access technologies and terminal devices being used, given that the service has been
subscribed.

7 IMT-2020 FMC service requirements

The IMT-2020 FMC service should be ubiquitously available. The end users can enjoy any application, from
any location, on any terminal device subject to any limitations imposed by the characteristics of the particular
access technologies and terminal devices being used.
The following sub-clauses identify the service requirements for IMT-2020 FMC.

7.1 Access service support

IMT2020 FMC is required to support access-independent service for users.
IMT2020 FMC is required to allow the user to select a suitable access connection to obtain service.

8 IMT-2020 FMC capability requirements

8.1 Customer-oriented ubiquitous broadband access and service environment

8.1.1 Description

With the blooming of mobile Internet, cloud computing, big data, and Internet of Things (IoT), as well as
industry Internet, the service objects of broadband networks will be further extended in the coming five to
ten years, from 5 billion people to 50 billion IoT terminals, and the broadband access service scenarios are
going ubiquitous, from ultra-broadband backbone, ultra-broadband access to ubiquitous broadband IoT.

The broadband access technical, such as IMT broadband network, WLAN broadband, and fixed broadband
are developing harmoniously to build a ubiquitous top-notch broadband network, where the advantages of
mobile broadband (convenience and wide coverage) and wired broadband (high bandwidth and reliability)
complement each other. FTTx and WLAN are used indoors, and IMT outdoors for GE fixed access and FE
mobile access. Ubiquitous broadband network together with plentiful applications such as smart home,
smart city, can offer users ubiquitous, seamless and perfect broadband experience.

8.1.2 Requirements
IMT-2020 FMC is required to provide the capabilities of customer-oriented ubiquitous broadband access
environment, i.e., access application servers or service platforms in a wide range including mobile, WLAN and
fixed access network.
