3.1 Terms p. 11
For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Edge Computing:
A concept, as described in TS 23.501, that enables operator and 3rd party services to be hosted close to the UE's access point of attachment, to achieve an efficient service delivery through the reduced end-to-end latency and load on the transport network.
Edge Computing Service Provider:
A mobile network operator offering Edge Computing service.
Edge Data Network:
A local Data Network that supports the architecture for enabling edge applications.
ECSP Management System:
is a part of 3GPP management system that utilizes 3GPP defined management services to enable consumers (e.g., ASP. ECSP) to orchestrate and manage the EDN.
PLMN Management System:
is a part of 3GPP Management System that utilizes 3GPP defined management services to enable consumers (e.g., PLMN operator) to orchestrate and manage the mobile networks.
Availability Zone:
Refer to GSMA Operator Platform Telco Edge Requirements [14].
Leading Operator:
The Leading Operator is the operator which consumes EDN shared by the PO.
Participating Operator:
The Participating Operator is the operator who provides its EDN to be shared with Leading Operator.

4 Concepts and overview p. 12
4.1 Concept of edge computing management p. 12
The edge computing services are provided by edge computing service providers (ECSP), application service providers (ASP), and PLMN operators (see Annex B in TS 23.558), where ASP is responsible for the creation of edge application servers (EAS) and application clients (AC), ECSP is responsible for the deployment of edge data networks (EDN) that contain EAS and EES, and PLMN operator is responsible for the deployment of 5G network functions, such as 5GC and 5G NR.
Figure 4.1-1 describes the edge computing management framework that contains PLMN management system and ECSP management system. ECSP management system, as the producer, provides management services enabling ASP and ECSP consumers to orchestrate and manage EDN NFs (e.g., EAS, EES, and ECS). PLMN management system, as the producer, provides management services enabling ECSP management system to interconnect EDN NFs with 5GC NFs (e.g., PCF, UPF, NEF). Both ECSP management system and PLMN management system communicate with ETSI NFV MANO to perform lifecycle management functions.
