co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.

INTRODUCTION
The market for car infotainment services (also known as "in-vehicle infotainment systems") has
been growing rapidly, as reflected by the growth of the associated industries. It is expected that
a variety of car infotainment (or multimedia) devices and services will be developed in the future.
Such devices include navigation, cameras, speakers, headrest displays, air-conditioners,
thermometers, heated seats, and lights. It is also expected that some devices will be developed
to provide 4-dimensional experiences for users.
Car infotainment systems typically include A/V features (such as standard radio and CD players),
and two-way communications tools, as well as hands-free phone connections, vehicle voice
commands, and other types of interactive audios or videos. Car infotainment systems have
evolved to allow passengers to watch movies and other visual media (for example, DVD players
installed on the rear seats). Another distinctive feature of future car infotainment systems is
mobile device connectivity. Newer vehicles provide a wide range of systems that allow devices
(e.g. smartphones and laptops) to be connected to a variety of services embedded in the vehicle.
From this observation, there is a crucial need for standardization to provide car infotainment
users with more enhanced services so as to easily manage and control infotainment devices as
well as content within a car.
The purpose of the IEC 63246 series is to specify the general considerations, requirements,
framework, and protocols to provide car users with the functionality of managing and controlling
device and content resources within a car.
The IEC 63246 series consists of the following parts:
– Part 1: General;
– Part 2: Requirements;
– Part 3: Framework; and
– Part 4: Protocol.
IEC 63246-1 describes the general considerations of CCIS, which includes the CCIS system
model and the types of CCIS users with the associated service flows.
IEC 63246-2 describes the requirements for CCIS, which include the CCIS functional entities,
the communication model, and the functional requirements.
IEC 63246-3 describes the CCIS framework, which includes the information flows between
functional entities and the CCIS operations, such as registration, device monitoring and control,
and data transfer.
IEC 63246-4 describes the CCIS protocol, which includes the protocol messages and
parameters, protocol procedures, implementation guidelines, etc.

4 System model
The CCIS service or system provides the CCIS users with a communication interface to easily
manage and control a variety of CCIS devices and CCIS profiles within the car, with the help of
the CCIS master, as shown in Figure 1. The CCIS system may be equipped within the car as a
built-in platform or by a software upgrade.

Figure 1 – CCIS environment
Figure 2 illustrates the system model of CCIS. The CCIS system connects the CCIS master to
a variety of CCIS devices within a car to manage and control the CCIS devices. The CCIS users
can use CCIS services through a communication interface with the CCIS master, in which a
CCIS user can control a CCIS device or enjoy the CCIS content contained in the device. For
this purpose, the CCIS master shall manage CCIS devices and CCIS profiles, such as device
status and availability, and a CCIS user can access CCIS devices via appropriate registration
and authentication processes with the CCIS master. A CCIS user can be categorized as follows:
car owner, temporary owner, private client, and public client.

5 CCIS users and service flows
5.1 Types of CCIS users
There is expected to be a wide variety of smart devices and CCIS profiles in the car. Depending
on the type of CCIS user, some devices can be allowed, whereas the others can be restricted
for use as CCIS services. In this respect, the types of CCIS users are categorized into the four
cases, as shown in Table 1.
Table 1 – Types of CCIS users
Classification Long-term use Short-term use
Owner Car owner Temporary owner
(authentication not required)
Client Private client Public client
(authentication required)

As shown in Table 1, a CCIS user is categorized into car owner, temporary owner, private client,
and public client, based on ownership and usage period, as follows:
– Car owner: a user who owns the car with a CCIS master and has the overall authority for
CCIS functions and services. Ownership of the car is long-term.
– Temporary owner: a user who takes the ownership from car owner temporarily (e.g. a car-
sharing or rental service user). The specific level of authority for use of CCIS services that
is given to a temporary owner may be pre-specified by the car owner.
– Private client: a user who can utilize the CCIS services in the long-term without ownership
(e.g., a family member of the car owner). The specific level of authority for use of CCIS
services that is given to a private client may be pre-specified by the car owner.
– Public client: a user who is not authenticated by the CCIS master yet (e.g. a guest). A public
client shall perform the registration and authentication process with the CCIS master.

---------------------- Page: 10 ----------------------
IEC 63246-1:2021  IEC 2021 – 9 –
The CCIS devices may be shared or not, depending on their features as follows:
– CCIS device sharing allowed (shared device): device shared by one or more users in the
car (e.g. air-conditioner and speaker);
– CCIS device sharing not allowed (personal device): device dedicated only to a particular
user type (e.g. headrest display and heated seat).
5.2 Service flows for Car Owner
5.2.1 Description
Figure 3 shows the service model, in which the car owner uses their own CCIS devices and
CCIS content.
Alice is working in the sales department of her company. The characteristics of her work lead
her to spend a lot of time in her car. Accordingly, she equipped her car with various devices,
such as an event video data recorder for road vehicle accidents (EVDR, see the IEC 63005
series), smart mirrors, cameras, a headrest display, and so on. In addition, she installed a CCIS
master to efficiently manage those devices.
One day, Alice made an appointment to sign a contract with her client. She jumped into her car
for a meeting. When she gets in the car, her smartphone automatically connects to the CCIS
master, and she asks a list of available CCIS devices and CCIS content from the CCIS master.
The CCIS master sends the available resource list of available CCIS devices and CCIS content
to Alice's smartphone. Because Alice wants to play her favourite music files stored in her
smartphone, she chooses to play the music files during her drive. After Alice arrived at the
meeting place, she closed the connection with the CCIS master and headed to the conference
room.
In this service model, there can be a security issue. An external user, who has not been
registered and authorized, can try to access the CCIS master, and then the external user can
try to add or remove a CCIS device with the authority of the car owner. Thus, the registration
and authorization with the CCIS master should be provided for the car owner.

Figure 3 – CCIS model for car owner
5.2.2 Service flows
Figure 4 shows the service flows associated with the service example in 5.2.1.

---------------------- Page: 11 ----------------------
– 10 – IEC 63246-1:2021  IEC 2021
1) When Alice is in the vehicle, her smart device is connected to the CCIS master and retrieves
a list of CCIS devices.
2) Alice selects a speaker from the CCIS device and the CCIS content list and sends an
occupancy request message to the CCIS master. Upon the request, the CCIS master sends
an occupancy notification to the speaker, and the speaker will respond with an occupancy
response to inform that the connection is ready. The CCIS master sends a device seize
acknowledgment to Alice. Alice plays music files that are stored in the smart device through
the speaker.
3) Alice releases the occupancy of the speaker, and terminates the connection with the CCIS
master. Then, the CCIS master changes the status of the speaker to available.

5.3 Service flows for temporary owners
5.3.1 Description
Figure 5 shows the service model in which the temporary owner is using a CCIS speaker device.

---------------------- Page: 12 ----------------------
IEC 63246-1:2021  IEC 2021 – 11 –
Bob, who travels for a holiday, will rent a car to travel comfortably. Bob, who chose the car, has
to go through the registration process as a temporary owner for the car to rent. A rental car
service manager with the authority of the car owner changes the mode of the CCIS master to
the temporary owner mode. After the mode change, Bob sends a temporary owner registration
request to CCIS master. Then, the service manager will set a period, and selectively accessible
CCIS device and CCIS content, and approves the request. The approved CCIS master registers
Bob as a temporary owner.
In the case of the temporary owner, additional procedures and certifications are required. For
example, it is necessary to define the period in which temporary owners can have the authority
of the owner and also to classify the CCIS devices and CCIS contents that can be accessed.

Figure 5 – CCIS model for temporary owner
5.3.2 Service flows
Figure 6 shows the service flows associated with the service example in 5.3.1.

---------------------- Page: 13 ----------------------
– 12 – IEC 63246-1:2021  IEC 2021

Figure 6 – Service flows for Temporary Owner
1) The first phase shows a car rental company's (administrator's) configuration of the CCIS
master's user mode. Note that CCIS devices and CCIS content capabilities provided by the
CCIS master can vary depending on the payment. First, the administrator requests the CCIS
master to modify the user mode. Then, the CCIS master provides the administrator with the
list of available CCIS devices and CCIS content. The administrator assigns an accessible
CCIS device access list to the CCIS master. With an assigned resource access list, the
CCIS master can change its user mode. When the CCIS master changes its user mode
successfully, the CCIS master confirms that the user mode was changed.
2) The second phase shows how Bob becomes an appropriate user of the CCIS master during
the rental period. Bob tries to connect to the CCIS master. Because Bob is not a registered
user, the CCIS master queries the car rental company for Bob's involvement. When the car
rental company grants Bob's involvement, the CCIS master informs Bob that he now has
the rights of a temporary owner.
5.4 Service flows for private client
5.4.1 Description
Figure 7 shows the service model in which a user registered the CCIS master as a private client
to use CCIS devices.
Alice got into her car to go to the movie cinema with her brother Chris over the weekend. Chris
tries to use Alice's headrest display in front of her seat to show her a list of movies he wants to
see. Chris's smartphone, which has already been registered as a private client, automatically
receives the CCIS device list from the CCIS master, and Chris has chosen the headrest display
in front of her seat. When selecting the movie is done, Chris tries to use the speakers to play
the music stored on his smartphone. Chris sends a request to the CCIS master so as to use the
speaker, and the CCIS master makes a request to Alice for permission to use the speaker,
which is a shared CCIS device. Having obtained an authorization from Alice, Chris played music
stored on his smartphone through the speakers.
