What is ISO 17515-2 - Intelligent transport systems about?
ISO 17515-2 is an international standard that provides specifications on the ITS-Station (ITS-S) access layer for a communication interface (CI) named "ITS-LTE-D2D".
ISO 17515-2 is appropriate in the context of LTE-D2D communications that are being used for the dissemination of ITS information from an ITS-SU to other ITS-SUs, where these ITS-SUs can be either vehicle ITS-SUs, roadside ITS-SUs, or personal ITS-SUs, as specified in ISO 21217.
ISO 17515-2 provides a combination of options from relevant ETSI/3GPP releases and ITS-station management standards in ISO 24102 to enable and achieve this objective. ITS-LTE-D2D CIs are based on the evolved-universal terrestrial radio access network (E-UTRAN) device-to-device (LTE-D2D) technology standardized at 3GPP Release 13.
ISO 17515-2 enables the use of the LTE-D2D technology as an ITS access technology in an ITS station by reference to respective specifications from 3GPP, and by specifying details of the Communication Adaptation Layer (CAL) and the Management Adaptation Entity (MAE) of CIs specified in ISO 21218.
Who is ISO 17515-2 - Intelligent transport systems for?
ISO 17515-2 on evolved universal terrestrial radio access network (E-UTRAN) is useful for:
- Emergency vehicle notification systems
- Telematics application developer
- Vehicle manufacturing companies
- Traffic signal control systems
- Traffic navigation systems
- ITS units stations
Why should you use ISO 17515-2 - Intelligent transport systems?
Localized communications are an essential component of hybrid communications in Intelligent Transport Systems (ITS). Various access technologies are suited for localized communications.
ISO 17515-2 focuses on the access technology known as LTE, which has captured the interest of a lot of ITS stakeholders in "Cooperative ITS" and "Urban ITS". It refers to a packet-switched cellular network technology specified by 3GPP. LTE also supports device-to-device communications (LTE-D2D), in addition to the "traditional" features of cellular networks, which can be efficiently used for ITS.
ISO 17515-2 provides complements to LTE-D2D specifications from 3GPP needed to operate it as an ITS access technology in an ITS station unit as specified in ISO 21217. Its implementation is referred to as an ITS-LTE-D2D communication interface (CI).
ISO 17515-2 can help its users for operating with the support of an LTE base station, and for operating without the support of an LTE base station, like from outside an LTE coverage area, as specified by 3GPP.
