This clause describes the relationship of edge computing service providers, PLMN operators, application service providers and end users, taking federation and roaming into account.

Figure B.2-1: Relationships involved in edge computing service – federation and roaming

The end user is the consumer of the applications provided by the application service provider (ASP). End user:

– can have ASP service agreement with a single or multiple application service providers.

– has a PLMN subscription arrangement with a PLMN operator (HPLMN). The UE used by the end user can register on the HPLMN network and network of its roaming partners.

– can have authorization to access edge services of a single or multiple ECSPs.

The ASP consumes the edge services (e.g. infrastructure, platform) provided by the ECSP. ASP:

– can have edge computing service provider service agreement with a single or multiple ECSPs.

The PLMN operator provides connectivity between the end user and the edge services provided by the ECSP. PLMN operator:

– can have the PLMN operator service agreement with a single or multiple ECSPs.

– can have service agreement for roaming including agreements for Edge Computing services, and/or federation with a single or multiple PLMN operators.

The ECSP provides the edge services. ECSP:

– can have PLMN operator service agreement with a single or multiple PLMN operators which provide edge computing support.

– can have federation partnership to share edge services with a single or multiple ECSPs.

The ECSP and the PLMN operator can be part of the same organization.
