Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

11.1 General

IMS CAMEL related subscription data, including O-IM-CSI, D-IM-CSI and VT-IM-CSI, are provisioned in the HSS and downloaded to the IM-SSF AS to support Customized Applications for Mobile network Enhanced Logic (CAMEL) feature for the IP Multimedia Core Network (IM CN) Subsystem, as defined in the 3GPP TS 23.278 [26].

This specification standardizes the coding of the IMS CAMEL subscription data based on XML when transported via Sh interface within the repository data and the associated service indications.

11.2 Service Indications

A dedicated Service Indication shall be used for IMS CAMEL services. The value of the Service Indication shall be "IMS-CAMEL-Services".

Proprietary extensions shall use not standardized Service Indications. There is no constraint for the data structure of the proprietary Service Data.

11.3 XML schemas

11.3.1 XML schema of IMS CAMEL Services
