Section: 6.6.2 Requirements
Content: The 5G system shall enable efficient delivery of content from a content caching application under the control of the operator (e.g. a cache located close to the UE). The 5G system shall support a content caching application in a UE under the control of the operator. The 5G system shall support configurations of content caching applications in the network (e.g. access network, core network), that provide content close to the UE. Based on operator policy, the 5G system shall support an efficient mechanism for selection of a content caching application (e.g. minimize utilization of radio, backhaul resources and/or application resource) for delivery of the cached content to the UE. The 5G system shall support a mechanism for the operator to manage content distribution across content caching applications. The 5G system shall support delivery of cached content from a content caching application via the broadcast/multicast service. For a 5G system with satellite access, the following requirement applies. - A 5G system with satellite access shall be able to optimise the delivery of content from a content caching application by taking advantage of satellites in supporting ubiquitous service, as well as broadcasting/multicasting on very large to global coverages.
