Section: 6.41.2.2 Configuration of Localized Services in Hosting Network
Content: NOTE: The term “Service provider of localized services” includes also 3rd party service provider. The 5G system 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 providers including network operators or 3rd party application providers. The 5G system shall support means for the service provider to request the hosting network via standard mechanisms to provide access to 3rd party services at a specific period of time and location. This period of time shall be flexible, so that a change in service provision can be decided at any time (e.g., to cancel or prolong local services in the locality of service delivery) based on localized services agreements. Based on localized services agreements, the 5G system shall provide suitable means to allow the service provider to request and provision various localized service requirements, including QoS, expected/maximum number of users, event information for discovery, network slicing, required IP connectivity etc, and routing policies for the application of the localized services via the hosting network. The 5G system shall support means for a hosting network to create policies and configure resources for the requested time and location for the 3rd party services based on the received request. The 5G system shall support means for a hosting network to notify the service provider of the accepted service parameters and routing policies. Subject to regulatory requirements and localized service agreements, the 5G system shall allow a home network operator to automatically negotiate policies with the hosting network for allowing the home network’s subscribers to connect at a specific occasion, e.g., time and location, for their home network services. Subject to the automatic localized services agreements between the hosting network operator and home network operator, for UE with only home network subscription and with authorization to access hosting networks the 5G system shall support: - access to the hosting network and use home network services or selected localized services via the hosting network, - seamless service continuity for home network services or selected localized services when moving between two hosting networks or a host network and the home network. The 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 their spatial extent (in terms of a particular topology, for example a single cell), as specified by a service provider of localized services. The 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 service provider of localized services. The 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. The 5G system shall support secure mechanisms to allow a home network to coordinate with a hosting network for a subscriber to temporarily access the hosting network (e.g., based on temporary credentials) at a given time (start time and duration) and location.
