1 Scope
This document provides the stage 3 specification of the PC2 reference point. The functional requirements and the
stage 2 procedures of the PC2 reference point are contained in 3GPP TS 23.303 [2]. The PC2 reference point lies
between the ProSe Function and ProSe Application Server.
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, version number, etc.) or
non-specific.
- For a specific reference, subsequent revisions do not apply.
- For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including
a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same
Release as the present document.

3.1 Definitions
For the purposes of the present document, the terms and definitions given in 3GPP TR 21.905 [1] and the following
apply. A term defined in the present document takes precedence over the definition of the same term, if any, in
3GPP TR 21.905 [1]. The term definition in the present document has a reference to that in 3GPP TS 23.303 [2].
Announcing UE: The UE that announces certain information that could be monitored by UEs in proximity that have
permission to discover.
Discoveree UE: The UE that receives the request message and responds with certain information related to the
discoverer UE's request.
Discoverer UE: The UE that transmits a request containing certain information about what it is interested to discover.

Monitoring UE: The UE that monitors certain information of interest in proximity of announcing UEs.
EPC-level ProSe Discovery: A ProSe Discovery procedure by which the EPC determines the proximity of two ProSe-
enabled UEs and informs them of their proximity.
Model A: involves one UE announcing "I am here" in restricted ProSe direct discovery.
Model B: involves one UE asking "who is there" and/or "are you
