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].

ProSe Function CTF (ADF): Accounting Data Forwarding (ADF) function block of the Charging Trigger Function (CTF) in the ProSe Function.

Usage information report: usage information related to one collection period.

Usage information report list: one or more usage information report(s) and associated with a UE identity.

Not served by E-UTRAN: the UE is either:

– outside of E-UTRAN coverage;

– within E-UTRAN coverage but not camped on any cell;

– within E-UTRAN coverage but camped on a non-E-UTRAN cell; or

– camped on an E-UTRAN cell not operating on the carrier frequency provisioned for ProSe direct service.

Open ProSe direct discovery: a type of ProSe direct discovery without explicit permission from the ProSe-enabled UE being discovered.

Restricted ProSe direct discovery: a type of ProSe direct discovery that only takes place with explicit permission from the ProSe-enabled UE being discovered.
