9.14  Service negotiation with underlying 3GPP network  p. 71

9.14.1  General  p. 71

This subclause describes the procedures for the VAE server to provide service requirements to the 3GPP network system. The Service Capability Exposure Function (SCEF) can be used for this purpose. As described in TS 23.682, the SCEF provides a means to expose the services and capabilities provided by 3GPP network interfaces and provides a means for the discovery of the exposed services and capabilities.

9.14.2  Information flows  p. 71

9.14.2.1  On-demand QoS request  p. 71

The information flow On-demand QoS request from VAE server (acting as SCS/AS) to SCEF over T8 reference point is specified in clause 5.11 in TS 23.682 (when setting up a session with required QoS).

9.14.2.2  On-demand QoS response  p. 71

The information flow On-demand QoS response from SCEF to VAE server (acting as SCS/AS) over T8 reference point is specified in clause 5.11 in TS 23.682.

9.14.2.3  Background data transfer request  p. 71

The information flow Background data transfer request from VAE server (acting as SCS/AS) to SCEF over T8 reference point is specified in clause 5.9 in TS 23.682 (resource management for background data transfer).

9.14.2.4  Background data transfer response  p. 72

The information flow Background data transfer response from SCEF to VAE server (acting as SCS/AS) over T8 reference point is specified in clause 5.9 in TS 23.682.

9.14.2.5  Network Status Request  p. 72

The information flow Network Status Request from VAE server (acting as SCS/AS) to SCEF over T8 reference point is specified in clause 5.8 in TS 23.682.

9.14.2.6  Network Status Response  p. 72

The information flow Network Status Response from SCEF to VAE server (acting as SCS/AS) over T8 reference point is specified in clause 5.8 in TS 23.682.

9.14.2.7  Network Status Report  p. 72

The information flow Network Status Report from SCEF to VAE server (acting as SCS/AS) over T8 reference point is specified in clause 5.8 in TS 23.682.

9.14.2.8  Network Status Acknowledgment  p. 72

The information flow Network Status Acknowledgment from VAE server (acting as SCS/AS) to SCEF over T8 reference point is specified in clause 5.8 in TS 23.682.

9.14.3  Communication of service requirements from the VAE server  p. 72

The procedure uses the APIs defined in subclause 5.8 in TS 23.682, 5.9 in TS 23.682 and 5.11 in TS 23.682 for setting up an AS session with required QoS procedure. This procedure defines the information elements that need to be exchanged between the VAE server (acting as SCS/AS) and the SCEF function during service negotiation.

9.14.4  Notification generation by the SCEF function  p. 72

The procedure notification generation by the SCEF function in response to the service requirements from the VAE server. The SCEF function notifies the VAE server if the service requirements can be satisfied. This procedure uses the APIs defined in subclause 5.8 in TS 23.682 for informing about potential network issues.
