Recent Advances in 3GPP Rel-12 Standardization related to D2D and Public Safety Communications Dorin Panaitopol*, Christian Mouton, Benoit Lecroart, Yannick Lair and Philippe Delahaye (previously with NEC Technologies (UK) Ltd., FMDC Lab., ComTech Department) Email: Dorin.Panaitopol@ 5 1 0 Abstract—The goal of this paper is to present ad- • GERAN (GSM EDGE Radio Access Networks), 2 vances on recent 3GPP standardization activities related responsible for the radio access specification of y to Device-to-Device (D2D) and public safety. The paper GSM/EDGE, a provides a clear 3GPP state of the art, including when the • RAN (Radio Access Networks), responsible for 3GPP work on D2D and public safety communications M started. Finally, it presents important conclusions with the definition of the functions, requirements and interfaces of UTRA/E-UTRA network, 6 respect to further 3GPP work on this topic. 2 Index Terms—D2D; Device-to-Device; ProSe; Public • CT (Core Network Terminals) responsible for ] Safety; Proximity Services; GCSE; Group Communica- specifying terminal interfaces (logical and physi- I tions; Group Communication System Enablers; 3GPP; cal), terminal capabilities (such as execution en- N LTE; LTE-A; Release 12; Rel-12; Release 13; Rel-13. vironments) and the core network part of 3GPP . s systems, c I.
