6 CI basic management
6.1 General
Basic management procedures related to communication interfaces (CI) shall access a “(Virtual)
Communication Interface” (CI/VCI) via the MI-SAP specified in ISO 24102-3.
Any change of status of a CI/VCI shall be reported to all ITS-SCUs with ITS-SCU-Mngmt-Request “VCI-
update” specified in ISO 24102-4. Reception of such a notification shall not be acknowledged.
Management communications with CIs/VCIs in other ITS-SCUs shall be with ITS station-internal
management communication PDUs “MI-rcmd”, “MI-rreq”, “MI-rget”, and “MI-rset” specified in ISO 24102-4.
Although SAPs and the related service primitives specified in ISO 24102-3 cannot be tested and are not

integral part of PDUs exchanged between physical entities in an ITS station using “ITS station-internal
management communications” specified in ISO 24102-4. As PDUs are testable, those elements of service
primitives that are part of a PDU become testable.

6.3 Cross-CI prioritization
6.3.1 General
Wireless TX-VCIs in an ITS station might suffer from cross-interference. This clause considers the case
that at least two local TX-VCIs, e.g. using the same medium, need to be synchronized in order to avoid
cross-interference. The procedure to synchronize transmission of multiple CIs based on user priority is
called “Cross-CI prioritization”.
The design and integration goal shall be to avoid such cross-interference as far as possible. A possible
means to achieve this is proper assignment of orthogonal wireless communication channels to the CIs.
Priority management across CIs is a somewhat slow process which requires involvement of the ITS
station management entity for every packet to be prioritized.
The procedure of cross-CI prioritization is an optional procedure. The part of it related to the CI is
specified in ISO 21218.
NOTE An implicit option of cross-CI prioritization is CI protection. A CI to be protected is a device for radio
communications such as passive transponder systems based on [2] and [3] which cannot harm other CIs.
In CI protection mode, the CI to be protected does not need to await the positive acknowledgement of a
prioritization request, but may try to perform communication at any time.
6.3.2 Registration of CI for prioritization request
Upon request of a CI to register for the cross-CI prioritization procedure by means of the MI-REQUEST
“PrioReg” specified in ISO 24102-3, the ITS station management entity shall
— create the header of the prioritization table for this CI (see Table 10) containing the Link-ID.LocalCIID
of the CI and the timeout information. The list entries “Request number”, “Priority”, and “Status”, if
already created, shall be set to zero,
— evaluate the list of MedType information contained in “PrioReg” in order to identify the LocalCIID of
all possible interferers in the ITS station, and

ISO 24102-1:2013(E)

— create an entry in the prioritization table for each identified interferer with the interferer LocalCIID
and with “Status Interferer” set to “released”.
6.3.3 Prioritization request
As specified in ISO 21218, a CI may request cross-CI prioritization by means of the MI-REQUEST “RTSreq”
specified in ISO 24102-3.
Upon reception of such a request, the ITS station management entity shall compare the pres
