Inter-Proximity-services (Prose) function signalling aspects; Stage 3
The present document describes the Diameter-based interfaces between the Proximity Services (ProSe) Function in the HPLMN and the ProSe Function in a local PLMN (PC6 interface) or between the Proximity Services (ProSe) Function in the HPLMN and the ProSe Function in a visited PLMN (PC7 interface).
This specification defines the Diameter application for PC6/PC7 reference points between the ProSe Functions. The interactions between the ProSe Functions are specified.
The stage 2 description for Proximity Services (ProSe) features in EPS is specified in 3GPP TS 23.303 [2].
