9.13.1 General

The VAE server supports monitoring of 3GPP systems’ network situation for V2X services. The VAE server receives and processes access network-related monitoring events/reports from SCEF (EPS entity of the 3GPP network system) as specified in 3GPP TS 23.682 [8]. The monitoring events/report may also include RAN-related resource/traffic situation information and QoS related notifications per UE or group of UEs. The VAE server initiates monitoring of the QoS for single or aggregately for groups of vehicles (supporting a V2X service and being in proximity) having ongoing sessions. The information from V2X UE related to monitoring events (e.g. location, groups, resource usage) can be available at the VAE server using the network resource management and location management services of the SEAL.

9.13.2 Information flows

9.13.2.1 Monitoring request

The information flow monitoring request from VAE server (acting as SCS/AS) to SCEF over T8 reference point is specified in clause 5.6 and clause 5.8 (when monitoring request comprises Network Status Request) in 3GPP TS 23.682 [8].

9.13.2.2 Monitoring response

The information flow monitoring response from SCEF to VAE server (acting as SCS/AS) over T8 reference point is specified in clause 5.6 and clause 5.8 (when monitoring request comprises Network Status Response) in 3GPP TS 23.682 [8].

9.13.2.3 Monitoring report

The information flow monitoring report from the SCEF to the VAE server over T8 reference point is specified in clause 5.6, clause 5.8 (when monitoring report comprises Network Status Information Report) and clause 5.11 (when monitoring report comprises notification of QoS/bearer level events) in 3GPP TS 23.682 [8].

9.13.3 Procedure

The VAE server acts as SCS/AS and initiates the procedure for monitoring with the SCEF as specified in the clause 5.6 and clause 5.8 in 3GPP TS 23.682 [8] by including the V2X application information corresponding to one or many V2X UEs.

The SCEF provides the monitoring reports (including the RAN related network situation information and QoS notification information for the corresponding V2X application, V2X UE or group of V2X UEs) to the VAE server as specified in the clause 5.6, clause 5.8 and clause 5.11 in 3GPP TS 23.682 [8].
