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 Direct Communication (using E-UTRAN or WLAN direct).
ProSe discovery identifies that ProSe-enabled UEs are in proximity, using E-UTRAN (with or without 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 can establish the communication path directly between two or more ProSeenabled 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 in TS 33.303 [29].
