1 Scope
The present document specifies the stage three (protocol description) of the Enhanced Calling Name (eCNAM)
supplementary service based on stage one description in 3GPP TS 22.173 [1]. It provides the protocol details in the IP
Multimedia (IM) Core Network (CN) subsystem (see 3GPP TS 24.229 [2]) based on the Session Initiation Protocol
(SIP) (see RFC 3261 [3]) where the eCNAM data is retrieved by the terminating network from trusted data sources.

document.

a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same
Release as the present document.

NOTE: Identity information takes the form of either a SIP URI (see RFC 3261 [3]) or a tel URI (see
RFC 3966 [7]).
Originating UE: sender of a SIP request intended to initiate either a dialog (e.g. INVITE, SUBSCRIBE), or a
standalone transaction.

the remote end.
Searchkey: a user identity employed to retrieve the eCNAM data associated with that identity from the appropriate data
sources.
terminating UE: recipient of a SIP request intended either to initiate a dialog or to initiate either a dialog or a
standalone transaction
trusted identity information: network generated user public identity information
For the purposes of the present document, the following definitions given in RFC 3261 [3] apply.
header
header field
request
response
session
(SIP) transaction
For the purposes of the present document, the following definitions given in ITU-T Recommendation I.210 [11] apply:
