9.11.1 General

The VAE server utilizes the NRM server of the SEAL to support the network resource management aspects towards the V2X applications. The VAE server supports the V2X UEs connected to EPS networks of different PLMN operators.

9.11.2 Information flows

9.11.2.1 V2X application requirement request

Table 9.11.2.1-1 describes the information flow V2X application requirement request from the V2X application specific server to the VAE server.

Table 9.11.2.1-1: V2X application requirement request

Information element	Status	Description
V2X UE ID	M (NOTE)	Identity of the V2X UE for which V2X application requirement is initiated.
V2X group ID	M (NOTE)	Identity of the V2X group for which the V2X application requirement is initiated.
V2X service ID	M	The V2X service ID for which application requirement corresponds to.
V2X application requirement	M	The requirement for application change. E.g. service levels for application service.
End point information	M	The end point information to which the notification shall be sent.
NOTE: Either of the information element should be present.

9.11.2.2 V2X application requirement response

Table 9.11.2.2-1 describes the information flow V2X application requirement response from the VAE server to the V2X application specific server.

Table 9.11.2.2-1: V2X application requirement response

Information element	Status	Description
Result	M	The result of the V2X application requirement request.

9.11.2.3 V2X application requirement notification

Table 9.11.2.3-1 describes the information flow V2X application requirement notification from the VAE server to the V2X application specific server.

Table 9.11.2.3-1: V2X application requirement notification

Information element	Status	Description
Result	M	The result of the network resource adaptation corresponding to the V2X application requirement.

9.11.3 V2X application resource adaptation

9.11.3.1 General

This subclause describes the procedure for V2X application resource adapation where the VAE server maps the V2X application requirement to network resource request for single or groups of V2X UEs.

9.11.3.2 Procedure

Figure 9.11.3.2-1 illustrates the procedure where the VAE server supports V2X application resource adaptation.

Pre-conditions:

1. The VAE server has the KPI information for the V2X services.

2. The VAE server is provided with the network monitoring information as per the subclause A.3.

3. The VAE server is configured with the NRM server information.

Figure 9.11.3.2-1: V2X application resource adaptation

1. The V2X application specific server sends a V2X application requirement request to the VAE server for an adaptation of the V2X service operation per V2X UE or per group of UEs.

2. The VAE server translates the V2X application requirement to different network resource requirement for group of users, which may be a subset of V2X UEs within the V2X group that will be affected by application adaptation.

3. If the V2X application requirement is successfully translated to the network resource requirement, the VAE server sends a V2X application requirement response to the V2X application specific server.

4. The VAE server performs network resource adaptation by interacting with the NRM server as specified in the 3GPP TS 23.434 [6] for the V2X application requirement received in step 1.

5. Based on the result of the network resource adaptation in step 4 corresponding to step 1, the VAE server sends a V2X application requirement notification to the V2X application specific server.
