1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

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.
Figure 4 – Service flows for car owner
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.
