<b>SREM</b>
</p>
<p>The SREM is transmitted based on the needs of the vehicle operator and triggered by applications. The application provides all data included in SREM. The traffic light control service shall construct a SREM payload and deliver it to the N&amp;T (Networking and Transport) layer for dissemination.</p>
<p>The SREM may be repeated (depending on data content and on implementation).</p>
<p>The SREM transmission may be terminated, if one of the following conditions is reached:</p>
<p class="b1+">Application requests the termination of SREM transmission.</p>
<p class="b1+">Application does not provide update for SREM at the expiry of the current SREM content.</p>
<p>
<b>SSEM</b>
</p>
<p>An ITS-S forwards the request to the local traffic controller (TLC) or to the traffic control center (TCC) for further operation. Based on the decision of the TLC or the TCC the ITS-S application generates a SSEM to inform the requestor and adjacent traffic participants (e.g. vehicles, pedestrians) about the status of the request.</p>
<p><span class="requality_text id_7fb00882-0b45-470f-9811-eecc0765b3a4"><a class="requality_id" id="id_7fb00882-0b45-470f-9811-eecc0765b3a4" name="7fb00882-0b45-470f-9811-eecc0765b3a4"/>The SSEM is transmitted by the infrastructure equipment (ITS-S road side unit) as response to a SREM.</span> <span class="requality_text id_434e85b1-2dd8-4a31-9f09-71a53ae86e2d"><a class="requality_id" id="id_434e85b1-2dd8-4a31-9f09-71a53ae86e2d" name="434e85b1-2dd8-4a31-9f09-71a53ae86e2d"/>Based on changes or incoming SREM with higher priority requests (e.g. public safety "overrules" a Bus request) a revised SSEM will be transmitted to reflect the new status.</span></p>
<p>The application provides all data included in SSEM payload. The Traffic Light Control service shall construct a SSEM payload and deliver it to the Networking and Transport Layer for dissemination.</p>
<p>The SSEM may be repeated (depending on data content and on implementation).</p>

<a name="_Toc455389639"/>8.4.3.1	TLC service service communication overview</h4>
<p>The SREM is transmitted on demand (e.g. Bus driver) or automatically by an application (e.g. in the bus) based on external conditions (e.g. position, reception of a specific SPATEM, etc.) It is transmitted once or continuously depending on the needs of the implementation. The SSEM is sent as response to a SREM. Both messages may use short range or wide area communication.</p>

<a name="_Toc455389640"/>8.4.3.2	TLC service communication parameters for short range access technologies</h4>
<p>For short range broadcast communication different access technologies are applicable for dissemination of the SREM or SSEM as follows:</p>
<p class="b1+">Short range communication data transmission using ITS-G5 broadcast transmission,</p>
<p class="b1+">WiFi communication.</p>
<p>In case the GN protocol and the GBC is used, the TLC service shall provide the destination area in the format compliant to ETSI EN 302 931 [9] and to the ITS networking &amp; transport layer.</p>
<p>Table 17 provides the requirements for the broadcast communication in accordance with ISO/TS 17423 [i.2].</p>
<p>The ITS station management uses the communication requirements to select suitable ITS-S communication protocol stacks. Some examples of communication parameter settings that fulfill these requirements are specified in clause 10.</p>

<p>For security against misuse of keys also for fix installations it is necessary to change the pseudonym identity regularly. The default time for is given in Table 4. For special cases like offline working traffic light controllers where manually driven provision of pseudonym identity keys is necessary, longer periods of e.g. half a year are allowed and should be agreed with the operator.</p>

<a name="_Toc455389643"/>9.1	Basic service overview</h2>
<p>Infrastructure ITS devices (e.g. road side unit) will communicate to vehicles/pedestrians and are on the other side connected to traffic controllers, traffic control centers (urban, interurban) or work in a standalone operation mode. From the application point of view, they use the same services like all other ITS stations (e.g. DEN, CA) and implement, depending on their role, additional infrastructure related applications.</p>

<p>Infrastructure ITS devices shall be able to transmit and to receive DENMs and provide the DEN (Decentralized Environmental Notification) service as defined in ETSI EN 302 637-3 [14]. Due to the role of the infrastructure device additional applications may run using the DEN basic service:</p>
<p class="b1+">Generation and transmission of DENM based on information of the directly attached devices (e.g. traffic light controller, traffic warning trailer).</p>
<p class="b1+">Generation and transmission of DENM based on traffic data received from the backbone traffic control infrastructure (e.g. traffic control center).</p>
<p class="b1+">Forwarding of DENM generated by the backbone ITS infrastructure (e.g. TCC) to other ITS stations (e.g. via ITS-G5, WLAN, cellular systems).</p>
<p class="b1+">Forwarding of DENM received from other ITS stations to the backbone ITS infrastructure (e.g. TCC).</p>

<p>Infrastructure ITS devices shall be able to transmit CAM's and provide the CA (Common Awareness) service as defined in ETSI EN 302 637-2 [13]. Due to the role of the infrastructure device additional applications may run using the CA basic service:</p>
<p class="b1+">Generation of CAM's for notification of protected communication zones (e.g. Tolling stations).</p>
<p class="b1+">Forwarding of CAM's received from other ITS stations to the backbone ITS infrastructure (this requires sufficient backbone channel capacity).</p>
<p class="b1+">Aggregation of CAM's (e.g. for purpose of acquisition of probe vehicle data) for minimizing backbone channel.</p>
