Study on 5G Networks Providing Access to Localized Services
The present document intends to capture the outcome of the study on use cases and potential new requirements for 5G networks providing access to localized services. The study aims to cover:
• use cases for enhanced 5G system support of a hosting network providing users/devices access to specific services, offered by the hosting network operator, other mobile operator(s) or 3rd party provider(s). Including scenarios where:
◦ Access to services through the hosting network could be on demand, temporary and/or cover specific location(s);
◦ The operator of the hosting network, or other mobile operator offering services to users, can be a PLMN or NPN operator;
◦ Different RATs (3GPP or non-3GPP) and spectrum (licensed or unlicensed) could be considered;
◦ The hosting network can also provide specific network services, e.g., location-based service, time synchronization etc.
• Investigate potential new service requirements, including:
◦ Enabling users/UEs to discover availability of specific target networks and specific services through a hosting network;
◦ Network functionalities to negotiate and configure access and requirements for a specific service (e.g., QoS, network slicing, charging, onboarding etc.);
▪ Can include policy management, service/QoS monitoring, and interaction between the hosting network and other mobile operator or 3rd party (offering the service) e.g., via API or other standard mechanisms
◦ Enabling users/UEs to concurrently use specific target services offered through a hosting network and the regular services offered by the HPLMN of the user/UE;
◦ Enabling access to the hosting network and specific services for users/UEs without previous relationship with the hosting network;
◦ Consideration of regulatory and security aspects.
• Gap analysis between potential new requirements and existing requirements and functionalities supported by 3GPP, e.g., VIAPA, NPN, slicing, QoS, etc.
