REMOTE COMMUNICATION FUNCTION
4.OPERATIONAL SCENARIOS
4.1Overview
Regulation (EU) No 165/2014 provides specific and controlled scenarios within which the Communication is to be used.
The scenarios supported are:
Communication Profile 1: Roadside inspection using a short range wireless communication Remote Early Detection Communication Reader instigating a physical roadside inspection (master-:-slave)
Reader Profile 1a: via a hand aimed or temporary roadside mounted and aimed Remote Early Detection Communication
Reader Profile 1b: via a vehicle mounted and directed Remote Early Detection Communication Reader
4.1.1Preconditions to data transfer via 5,8 GHz DSRC interface
NOTE: In order to understand the context of the preconditions the reader is referred to Figure 14.3 below.
4.1.1.1Data held in VU
DSC_12
The VU shall be responsible to keep updated every 60 seconds and maintain the data to be stored in the VU, without any involvement of the DSRC communication function. The means by which this is achieved is internal to the VU, specified in Regulation (EU) No 165/2014, Annex 1 C, section 3.19 ‘Remote communication for targeted roadside checks’ and is not specified in this Appendix.
4.1.1.2Data provided to DSRC-VU Facility
DSC_13
The VU shall be responsible to update the DSRC tachograph data (the Data) whenever the data stored in the VU is updated at the interval determined in 4.1.1.1 (DSC_12), without any involvement of the DSRC communication function.
DSC_14
The VU data shall be used as a basis to populate and update the Data, the means by which this is achieved, is specified in Annex 1.C, section 3.19 ‘Remote communication for targeted roadside checks’ or if there is no such specification it is a function of product design and is not specified in this Appendix. For the design of the connection between DSRC-VU facility and the VU, please refer to section 5.6.
4.1.1.3Content of the Data
DSC_15
The content and format of the Data shall be such that, once decrypted, it shall be structured and made available in the form and format specified in 5.4.4 of this Appendix (Data structures).
4.1.1.4Data presentation
DSC_16
The Data, having been kept frequently updated in accordance with the procedures determined in 4.1.1.1, shall be secured prior to presentation to the DSRC-VU, and presented as a secured data concept value, for temporary storage in the DSRC-VU as the current version of the Data. This data is transferred from the VUSM to the DSRC function VUPM. The VUSM and VUPM are functions and not necessarily physical entities. The form of physical instantiation to perform these functions shall be a matter of product design unless specified elsewhere in Regulation (EU) No 165/2014.
4.1.1.5Security data
DSC_17
Security data (securityData), comprising the data required by the REDCR to complete its ability to decrypt the Data shall be supplied as defined in Appendix 11 Common Security Mechanisms and presented as a data concept value, for temporary storage in the DSRC-VU as the current version of securityData, in the form defined in this Appendix section 5.4.4.
4.1.1.6VUPM data available for transfer across the DSRC interface
DSC_18
The data concept which shall always be available in the DSRC function VUPM for immediate transfer upon request by the REDCR is defined in section 5.4.4 for full ASN.1 Module specifications.
General overview of communication Profile 1
This profile covers the use case where an agent of the competent control authorities, uses a short range remote communication Remote Early Detection Communication Reader (5.8 GHz DSRC interfaces operating within ERC 70-03, and tested against the appropriate parameters of EN 300 674-1 as described in section 5) (the REDCR) to remotely identify a vehicle which is potentially in violation of Regulation (EU) No 165/2014. Once identified, the agent of the competent control authorities who is controlling the interrogation decides whether the vehicle should be stopped.
4.1.2Profile 1a: via a hand aimed or temporary roadside mounted and aimed Remote Early Detection Communication Reader
In this use case the agent of the competent control authorities is situated at the roadside, and aims a hand held, tripod mounted, or similar portable, REDCR from the roadside towards the centre of the windshield of the targeted vehicle. The interrogation is made using 5.8 GHz DSRC interfaces operating within ERC 70-03, and tested against the appropriate parameters of EN 300 674-1 as described in section 5. See Figure 14.1 (Use Case 1).
4.1.3Profile 1b: via a vehicle mounted and directed Remote Early Detection Communication Reader (REDCR)
In this use case the agent of the competent control authorities is situated within a moving vehicle, and either aims a hand held, portable REDCR from the vehicle towards the centre of the windshield of the targeted vehicle, or the REDCR is mounted within or on the vehicle so as to point towards the centre of the windshield of the targeted vehicle when the Remote Early Detection Communication Reader's vehicle is in a particular position relevant to the targeted vehicle (for example directly ahead in a stream of traffic). The interrogation is made using 5.8 GHz DSRC interfaces operating within ERC 70-03, and tested against the appropriate parameters of EN 300 674-1 as described in section 5. See Figure 14.2. (Use Case 2).
