42、5.0.0 (2018-07)73GPP TS 24.196 version 15.0.0 Release 154 Enhanced Calling Name (eCNAM) 4.1 Introduction The eCNAM service provides the terminating user with the name associated with the originating user and optionally delivers metadata about that originating user. While eCNAM is a terminating servi
43、ce, the eCNAM operations rely on information received from the originating network, such as the originating users E.164 telephone number (TN) to retrieve eCNAM data from trusted data sources (via methods outside the scope of this specification). 4.2 Service Description 4.2.1 General Description The
44、eCNAM service provides the terminating user with a name that identifies the originating user, and metadata about that originating user (e.g., address, language). NOTE: The terminating service provider retrieves the name and metadata from pre-selected data sources. The terminating service provider ca
45、n also partner with analytics providers that offer risk indicators about the incoming call (e.g., known perpetrators of scams) as part of the metadata eCNAM delivers. To retrieve eCNAM data, the service provider formulates queries using a searchkey to retrieve the name and metadata. The searchkey is
46、 a user identity obtained from the incoming SIP INVITE. Most commonly, the service provider uses an E.164 TN as that searchkey. Other identities could be used to retrieve the eCNAM data. If the terminating network determines that the telephone numbers (or other identitys) presentation is restricted
47、(i.e., not to be presented to the end user), the eCNAM data will also be restricted. If the terminating network determines that the telephone number (or other identitys) presentation is not restricted (i.e., to be presented to the end user), the eCNAM data will also be presented to the end user with
48、 no restriction. 4.3 Operational Requirements 4.3.1 Provision/withdrawal The eCNAM service can be provided after prior arrangement with the service provider. The eCNAM service can be withdrawn at the subscribers request or for administrative reasons. 4.3.2 Requirements on the Originating Network eCN
49、AM is a terminating service, however, the eCNAM operations rely on information received from the originating network. If the originating user identity, such as the originating users E.164 TN, is not delivered by the originating network to the terminating network, the terminating service provider will not be able to retrieve eCNAM data from the relevant data sources. NOTE: The searchkey element necessary for retrieving eCNAM data from the relevant data source is, in most cases, restricted to the originating users E.164 TN for most
