WEB SERVICES INTERFACE

摘要

A Call Session Control Function (CSCF) entity in an IP Multimedia Subsystem (IMS) network comprises a first interface for interfacing with other entities and uses signalling in an Extensible Markup Language (XML) format. The other entities that the CSCF interfaces with can be located outside the IMS network, such as servers supporting third party IT or web-based applications, or within the IMS network. The CSCF directs XML based service requests by filtering XML messages received via the first interface.
