CPR # Consolidated Potential Requirement Original PR # Comment
CPR 6.1-001The 5G network shall support suitable mechanisms to allow automatically establishing localized service agreements for a specific occasion (time and location) and building temporary relationship among hosting network operator and other service operators including network operators or 3rd party service providers.PR.5.3.6-1
CPR 6.1-002The 5G system shall support means for the service operator to request the hosting network via standard mechanisms to provide access to 3rd party services at a specific period of time and location.

CPR 6.1-009The 5G System shall support a mechanism to enable configuration of a network that provides access to localized services such that the services can be limited in terms of the resources or capacity available, to correspond to requirements that apply only to the locality of service delivery, as specified by a 3rd party.PR.5.10.6-2
CPR 6.1-010The 5G system shall support means for a hosting network to provide a 3rd party service provider with information for automatic discovery of the hosting network by the UEs to allow access to specific 3rd party services.PR.5.6.6-1
