The objective is to study use cases and identify potential requirements for operator network controlled
discovery and communications between UEs that are in proximity, under continuous network control, and
are under 3GPP network coverage, for:
Integration of current infrastructure services, to assure the consistency of the user experience including
reachability and mobility aspects
Additionally, the study item will study use cases and identify potential requirements for
Public Safety, in case of absence of E-UTRAN coverage (subject to regional regulation and operator policy, and
limited to specific public-safety designated frequency bands and terminals)
Use cases and service requirements will be studied including network operator control, authentication, authorization, accounting and regulatory aspects.
The study does not apply to GERAN or UTRAN.
