Extensible Markup Language (XML) Configuration Access Protocol (XCAP) over the Ut interface for Manipulating Supplementary Services
The present document defines a protocol used for manipulating data related to supplementary services. The protocol is based on the eXtensible Markup Language (XML) Configuration Access Protocol (XCAP) RFC 4825 [8]. A new XCAP application usage is defined for the purpose of manipulating the supplementary services data. The common XCAP related aspects that are applicable to supplementary services are specified in the present document. The protocol allows authorized users to manipulate service‑related data either when they are connected to IMS or when they are connected to non‑IMS networks (e.g. the public Internet).
The present document is applicable to User Equipment (UE) and Application Servers (AS) which are intended to support XCAP application usage for manipulating data related to supplementary services.
