In Figure 9-3, the networked vehicle related to the support of NGN capabilities is located in the end
user functions. Vehicle-specific applications in the NGN-based applications are supported through
the NGN for situations such as an emergency call or a public telecommunication.

NOTE – The NGN-capable networked vehicle and ITS infrastructure are the end user function in the NGN
perspective [b-ITU-T Y.2291], the residential home network is located in the 'Other networks' box in
Figure 9-3.

10 Security considerations
Security is an important issue for a networked vehicle. Different levels of security requirements
need to be applied according to the environment where the networked vehicle is located, for
example, when it is moving or stationary in a home network environment. Security requirements
identified in [ITU-T Y.2201], [ITU-T Y.2701] and [ITU-T Y.2702] are applicable whenever the
networked vehicle operates in NGN environments. Other cases of security requirements are out of
scope of this Recommendation.
