8.10 Utilizing 3GPP core network capabilities
23.5583GPPArchitecture for enabling Edge ApplicationsRelease 18TS
8.10.1 General
The functional entities of the Edge Enabler Layer can utilize the 3GPP core network capabilities (i.e. 5GC, EPC) to fulfill the needs of the edge service operations. This clause specifies the details of the 3GPP core network capabilities consumed by each functional entity.
8.10.2 Capabilities utilized by ECS
When required, the ECS may utilize:
– user plane path management events by subscribing with the 3GPP core network for the user plane path management event notifications of the UE as described in 3GPP TS 23.501 [2] and 3GPP TS 23.502 [3]; and
– the location information from the API exposed by 3GPP core network, e.g. SCEF/NEF/SCEF+NEF or LCS (Location Service) as specified in 3GPP TS 23.682 [17], 3GPP TS 23.502 [3], 3GPP TS 23.271 [7], 3GPP TS 36.305 [8], 3GPP TS 23.273 [9] and 3GPP TS 38.305 [10] to obtain the UE’s location from the 3GPP Core Network.
8.10.3 Capabilities utilized by EES
When required, the EES may utilize:
– AF traffic influence functionality, including the user plane path management event notifications of the UE, from the 3GPP core network as described in 3GPP TS 23.501 [2] and 3GPP TS 23.502 [3];
– the location information from the API exposed by 3GPP core network, e.g. SCEF/NEF/SCEF+NEF or LCS (Location Service) as specified in 3GPP TS 23.682 [17], 3GPP TS 23.502 [3], 3GPP TS 23.271 [7], 3GPP TS 36.305 [8], 3GPP TS 23.273 [9] and 3GPP TS 38.305 [10] to obtain the UE’s location from the 3GPP Core Network;
– capabilities exposed by the 3GPP core network, e.g. NEF or PCF, to establish an AF session with QoS, and QoS related event notifications subscribed with the 3GPP core network as specified in 3GPP TS 23.501 [2], 3GPP TS 23.502 [3] and 3GPP TS 23.503 [12];
– capabilities exposed by the 3GPP core network, e.g. NEF or NWDAF, to analyse UE expected behaviour as specified in 3GPP TS 23.288 [18]; and
– the monitoring capability exposed by the 3GPP core network as specified in 3GPP TS 23.501 [2] and 3GPP TS 23.502 [3].
