7.4.5 Use case D – On-demand functions for privately owned vehicle

Through vehicle APPs available on smart devices and on the VMS, the vehicle user can demand
vehicle functions that he can subscribe to against a fee for one-time use, a certain duration or over the
vehicle's lifetime. Examples for such functions could be premium on-demand autonomous driving
functions, longer battery range, on-demand navigation, 3D video, AR/VR games, digital radio, etc.
The requirement is that safety functions should not be part of such on-demand functions.

Based on user interests, services can be proposed to the customer actively through the app. Some of
these on-demand functions will be directly displayed or linked to the VMS.
In the vehicle the VMS displays a choice of on-demand functions. The passenger can choose a
function and the duration of the subscription through interaction with the VMS. Based on the VMS
payment profile for that user deposited in the cloud, a passenger can pay after secure identification
through the VMS. Alternatively, payment may not require a user profile and/or an in-app payment
could be used. VMS confirms the purchase and displays the chosen function that is ready for use.

7.4.5.1 Requirements
R1: The VMS should enable a centralized or individual access in a multi-passenger vehicle to the
cloud with app for on-demand functions and payment functions.

R2: For on-demand functions and payment functions, the VMS in a multi-passenger vehicle should
have access to the VMS user profiles at a centralized or individual position.

R3: VMS should be equipped with sensors allowing the identification passenger(s) at different
positions for usage and payment functions or with an input function allowing the user to identify
himself through a password.

R4: VMS should support on-demand functions that are meant to run locally on VMS such as on-
demand navigation, 3D video, AR/VR games, digital radio, etc.

– VMS must have enough storage space
– VMS must have enough calculation power
– For multi-passenger vehicles individual VMS at each passenger seat should respond to these
prerequisites.

7.5 Continuous and consistent services across various networks and environment (from/to
VMS)
7.5.1 Use case A – Continuity of service

During breakfast, a person starts to watch a live streaming of a basketball game using an APP on a
tablet through the Wi-Fi network at home. After breakfast, the video of the basketball game is paused.
Meanwhile, the viewing records (i.e., the program that is being watched, the time when the video is
paused, the preferred audio commentary track, etc.) are uploaded to a cloud database automatically.
The individual steps into a waiting vehicle and subsequently decides to continue to watch the live
broadcasting of the basketball game en route to the office with the in-vehicle display or windshield
display through the converged network. In the vehicle, the individual may log into an application in
the VMS with the same user account to continue viewing. Meanwhile, the viewing records are
downloaded from the cloud database to the VMS. In such a case, the account information and viewing
records can be used to support continuous and consistent services across various networks and on
multiple screens providing an improved viewing experience. For example,
1) Suppose the live streaming of the basketball game is available on both satellite broadcast
networks and cellular communication networks. If the person has a premium subscription,
then the high-definition (HD) live broadcasting of the basketball game with HD surround
sound available on the satellite broadcast network may be enjoyed. If the person has a
