ETSI ETSI TS 123 303 V13.6.0 (2017-01)83GPP TS 23.303 version 13.6.0 Release 131 Scope The present document
45、specifies the Stage 2 of the Proximity Services (ProSe) features in EPS. ProSe features consist of: ProSe discovery (direct or EPC-level) and ProSe Direct Communication (using E-UTRAN or WLAN direct). ProSe discovery identifies that ProSe-enabled UEs are in proximity, using E-UTRAN (with or without
46、E-UTRAN) or EPC. ProSe Direct Communication enables establishment of communication 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 ca
47、n 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-
48、UTRAN and UEs. Security aspects of ProSe are defined in TS 33.303 29. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, ver
