3.1 Definitions

For the purposes of the present document, the following terms and definitions apply:

Call Session Control Function (CSCF): See 3GPP TS 23.002 [1].

dialog: See IETF RFC 3261 [10].

header: See IETF RFC 3261 [10].

header field: See IETF RFC 3261 [10].

identity information: all the information identifying a user, including trusted (network generated) and/or untrusted (user generated) addresses

NOTE: Identity information takes the form of either a SIP URI (see IETF RFC 2396 [8]) or a "tel" URI
(see IETF RFC 3966 [9]) .

incoming initial request: all requests intended to initiate either a dialog or a standalone transaction terminated by the served user

Interconnection Border Control Function (IBCF): See 3GPP TS 23.228 [2].

Media Gateway Control Function (MGCF): See 3GPP TS 23.002 [1].

originating UE: sender of a SIP request intended to initiate either a dialog (e.g. INVITE, SUBSCRIBE), or a standalone transaction


outgoing (communication): communication outgoing from the user side of the interface

outgoing initial request: all requests intended to initiate either a dialog or a standalone transaction received from the served user

private information: information that according to IETF RFC 3323 [6] and IETF RFC 3325 [7] is not permitted to be delivered to the remote end.

proxy: See IETF RFC 3261 [10].

Proxy‑CSCF (P‑CSCF): See 3GPP TS 23.228 [2].

public user identity: See 3GPP TS 23.228 [2].

request: See IETF RFC 3261 [10].

response: See IETF RFC 3261 [10].

Serving‑CSCF (S‑CSCF): See 3GPP TS 23.228 [2].

session: See IETF RFC 3261 [10].

standalone transaction: SIP transaction that is not part of a dialog and does not initiate a dialog

NOTE: An OPTIONS or a MESSAGE request sent outside of a SIP dialog would be considered to be part of a standalone transaction.

supplementary service: See ITU‑T Recommendation I.210 [12], clause 2.4.

tag: See IETF RFC 3261 [10].

terminating UE: recipient of a SIP request intended either to initiate a dialog or to initiate either a dialog or a standalone transaction
