ETSI ETSI TS 123 303 V15.1.0 (2018-07)83GPP TS 23.303 version 15.1.0 Release 151 Scope The present document specifies the Stage 2 of the Proximity Services (ProSe) features in EPS. ProSe features consist of: ProSe discovery (direct or EPC-level) and ProSe Di

48、rect Communication. ProSe discovery identifies that ProSe-enabled UEs are in proximity, using E-UTRAN (with or without E-UTRAN), WLAN technology or EPC. The details of WLAN-based ProSe Direct Discovery are described in clause 5.3.1.3 and Annex C. ProSe Direct Communication enables establishment of c

49、ommunication paths between two or more ProSe-enabled UEs that are in direct communication range. The ProSe Direct Communication path could use E-UTRAN or WLAN. For Public Safety specific usage: - ProSe-enabled Public Safety UEs can establish the communication path directly between two or more ProSe-enabled Public Safety UEs, regardless of whether the ProSe-enabled Public Safety UE is served by E-UTRAN. - ProSe Direct Communication is also facilitated by the use of a ProSe UE-to-Network Relay, which acts as a relay between E-UTRAN and UEs. Security aspects of ProSe are defined
