18、n Standard, equipment procured and installed in accordance with ENV 13372 has been considered when drafting this European Standard. Operation of such equipment and procurement of additional equipment for systems based on such equipment can continue with reference to Directive 93/36/EEG Article 8 ite
19、m 3c. This document forms part of a series of European Standards defining the framework of a Dedicated Short Range Communication (DSRC) link in the Road Transport and Traffic Telematics (RTTT) environment. The communication requirements of many RTTT applications can be fulfilled by DSRC. The DSRC St
20、andards enable compliant communication systems to serve multiple RTTT applications in parallel. The small service areas and severe real-time constraints require a specific protocol architecture leading to the reduced protocol stack shown in Figure 1, consisting of the Application Layer, the Data Lin
21、k Layer, and the Physical Layer. Such an architecture is very common for real-time environments. This document deals with the interlayer management of the DSRC protocol stack. Figure 1 DSRC protocol stack The following set of documents for the DSRC link is issued by CEN: EN 12253 Road transport and

23、 - Dedicated Short Range Communication (DSRC) DSRC application layer EN 13372 Road Transport and Traffic Telematics (RTTT) Dedicated short-range communication - Profiles for RTTT applications EN 13372:2004 (E) 5 1 Scope This document specifies DSRC profiles which provide coherent sets of communicati
24、on tools for applications based on DSRC. These sets consist of subsets of functionality described in EN 12253, EN 12795 and EN 12834, out of which a minimum subset is mandatory. The DSRC Standards EN 12253, EN 12795 and EN 12834, which together form a three-layered architecture for DSRC, are designe
25、d to encompass a wide range of services for different purposes in order to make the basic DSRC architecture suited for many different applications and for a wide range of possible products and systems. DSRC systems can be built using one-way (downlink) or two-way (interactive) communication. The DSR
26、C profiles described in this document are intended for interactive DSRC systems based on two-way communication and DSRC systems using one-way communication (broadcast services). While EN 12253 contains very little variation, EN 12795 and especially EN 12834 describe a wide range of communication ser
27、vices. It has not been considered feasible to assume that any one piece of equipment is designed to implement all of these services. It is often the case that the functionality of the on board unit is more limited than the functionality of the roadside unit. This document covers Physical Layer param

39、 Road Transport and Traffic Telematics TC Technical Committee UI Unnumbered Information UNI Standards institute of Italy VST Vehicle Service Table 5 DSRC profiles overview In the European DSRC Standards each consistent and standardised set of communication protocol parameter values is called a DSRC
40、profile and is assigned a unique identifier number. The word profile is a reserved word in EN 12834 and is used in the definition of the BST and VST. Each profile is made up of a set of parameter values and/or functionality from each layer. Profiles are not registered but defined by this document. F
41、uture extension of the number of profiles defined by this document, made necessary by the introduction of new application and/or configurations, will be undertaken by means of revision of this standard. When OBUs arrive at the DSRC communication zone, the use of one profile is negotiated between the
42、 RSU and the OBU. The initialisation and negotiation procedure is described in EN 12834. Each DSRC profile is identified by a unique number of ASN.1 type “Profile“. One or more DSRC profile numbers are broadcasted by the RSU in the BST according to site-specific rules. Only OBUs being able to use at
43、 least one of the DSRC profiles offered by the RSU are allowed to answer, see clause 7.1.2 and EN 12834.This issue of EN 13372 defines two closely related profiles differing only in one parameter of EN 12253 (i.e. the Sub-carrier Frequency on uplink) while using the same subsets of functionality fro
44、m EN 12795 and EN 12834. Future revisions of this document may introduce additional profiles using other subsets of functionality from EN 12253, EN 12795 and EN 12834. This document also allows for private profiles enabling system implementers to realise additional functionality not provided by prof
45、ile content defined in this document or a subsequent revision of this document. 6 DSRC parameters and subsets 6.1 Physical layer 6.1.1 Overview EN 12253 specifies the physical layer parameters for uplink and for downlink. For some parameters there are alternative values. Wherever the exact choice of
46、 one value among its alternatives needs to be made known to the communication partner, profiling is used to define which of the alternative values is chosen and the profile number indicates the choice to the communication partner. The alternative values are listed in Table 1. EN 13372:2004 (E) 8 Tab
47、le 1 Physical layer parameters with alternative values Parameter Values Comment D1 Downlink Carrier Frequencies There are four alternatives: 5,7975, 5,8025, 5,8075 and 5,8125 GHz Carrier Frequencies may be selected by the implementer of the roadside system and need not be known in the OBU. D2 RSU Tr
48、ansmitter Spectrum Mask There are three alternatives: class A, B or C. Parameter for controlling interference between RSUs. A suitable class may be selected by the implementer of the roadside system and need not be known in the OBU. OBUs shall be able to function properly with any class of RSU. Class A shall not be used in new installations. D11a Power Limit for communication (upper) There are two alternatives: D11a-0: -24 dBm or D11a-1: -17 dBm The alternative to be chosen is stated in 6.1.2 for Set L1-A and 6.1.3 for Set L1-B. D12 Cu
