5.1.1 Introduction

23.947
5.1.3.1 General
From the developer’s point of view, it is essential to understand which entity handles which tasks in the EDGEAPP system. The AC is deliberately kept simple: it talks only to the EEC, and all network complexity is abstracted away. When the AC is designed, only the calls to the EEC’s APIs need to be implemented to lever...

5.1.3.2 AC Discovering the Serving EES
The EEC running in the UE, needs to discover its EES. The EEC can learn which EES to register with through multiple mechanisms: • Pre-provisioned in the UE/application profile. • DNS-based discovery, using operator domain naming conventions. • Network-provisioned, delivered at onboarding or during mobile...

23.947
5.1.3.3 CAPIF roles of EDGEAPP entities
While AC does not interact directly with CCF, it is important to understand the roles that each EDGEAPP entity plays in relation to CAPIF to consume APIs. In this use case, the EEC behaves as a CAPIF API Invoker. The EEC needs to discover EAS APIs and obtain OAuth tokens to consume them. In particular, the EEC queries ...

5.1.4 Use case Flows

2b5c82519cec48b309e29881d9c51555
23.947
5.1.4.1 General
From a developer’s perspective, the use case flows describe how an Application Client (AC) interacts with its local Edge Enabler Client (EEC) to request services, discover the right Edge Application Server (EAS), and sustain service continuity when the UE moves between edge zones. The AC is abstracted from all network-...
2b5c82519cec48b309e29881d9c51555
23.947
5.1.4.2 Step 1: AC Registration & Provisioning
The first step is for the AC to register with the EEC so that it can start consuming services. The developer must ensure the AC calls the Eeec_ACRegistration API. If the EEC already aware of its serving EES (through provisioning, DNS discovery, or cached state), it registers directly as depicted in Figure 5.1.4.2-1. Ot...
2b5c82519cec48b309e29881d9c51555
23.947
5.1.4.3 Step 2: EAS Discovery
Once registered, the AC needs to know which EAS can provide the video analytics service. The developer calls Eeec_EASDiscovery, and the EEC queries the EES to find suitable EAS instances in the serving zone. The response includes candidate EAS endpoints, which the EEC returns to the AC via callback. The flow is shown i...
2b5c82519cec48b309e29881d9c51555
23.947
5.1.4.4 Step 3: CAPIF API Discovery
The AC now requires the actual API contract to interact with the selected EAS. The developer does not handle CAPIF directly; instead, the EEC calls CAPIF_Discover_Service_API towards the CCF. CAPIF responds with the API base URI, supported operations, and authorization details. The EEC then informs the AC via a respons...
2b5c82519cec48b309e29881d9c51555
23.947
5.1.4.5 Step 4: Service Invocation
With the endpoint and API details, the AC begins sending its video stream directly to the EAS. From the developer’s perspective, this involves implementing the client logic that captures frames and invokes the Video Analytics service API as specified by CAPIF. The EAS processes the video in real time and returns crowd ...
2b5c82519cec48b309e29881d9c51555
23.947
5.1.4.6 Step 5: Mobility with Application Context Relocation
The EEC does not detect mobility itself. Mobility/zone-change is determined in the network and conveyed to the EES (e.g., via operator control-plane and exposure functions). The EES then informs the EEC over EDGE-1 using the service continuity/mobility procedures. The EEC translates that into the local EDGE-5 notificat...
2b5c82519cec48b309e29881d9c51555
23.947
5.1.4.7 Step 6: API Update & Resume Streaming
After relocation, the EEC refreshes API discovery with CAPIF to retrieve the new endpoint for EAS 2. The AC receives this updated endpoint via notification callback. The developer must handle this event by re-establishing the video stream to EAS 2 using the new service API. From the AC’s perspective, this looks like a ...

4.1 Overview
The study builds upon the management services exposure scenarios defined in clause 5.6 of TS 28.533 [2], which serves as the primary reference for exposing management services to external consumers. In addition, the Management Exposure framework described in TS 28.579 [3] introduces an optional approach based on CAPIF....

28.888
4.2.1 Introduction
As noted in clause 5.6 of TS 28.533 [2], an operator can decide to expose 3GPP management system capabilities to external MnS consumers using existing MnS interfaces (e.g. external MnS consumer Y1), or using CAPIF (e.g. external MnS consumer Y2). When CAPIF is not used, an external MnS consumer gets access to MnS API...

4.2.2 Authorization in CAPIF Framework
3GPP TS 33.122 [7] specifies security aspects of the CAPIF Framework. CAPIF has defined three possible formats for access token’s scope. These formats are specified in the “scope” attribute in AccessTokenReq (see clause 8.5.4.2.6 of TS 29.222 [8]) and AccessTokenRsp (see clause 8.5.4.2.7 of TS 29.222 [8]). 4.3 Acces...
