Integrating IMS with web services to enable IP Multimedia Service Oriented Architectures

The IP multimedia subsystem has provided major advances for IP-based telecom infrastructures and services. The IMS core network enables a variety of IMS-compliant communications services to interoperate while being accessed through different kinds of access networks, preferably broadband. As both consumer and corporate users are by now used to access services, even communications services through the Web and Web-based communities and social networks, it is key for success of IMS-based services to be provided with efficient Web access, so users can benefit from those new services by using Web-based applications and user interfaces, not only IMS user equipments and SIP protocol. HP CMS has developed the mobile personal community broadcasting (MPCB) service, an IMS / Web 2.0 Live Group Video Share application that is an example of IMS video solution with strong Web 2.0 integration. The efficient integration of IMS and SOA architectures will be essential to achieve the desired goals. Both parlay-X standard WSDL should be supported as well as innovative Web 2.0 web services SDK. One of the key network elements in integrated IMS-SOA environments is the telecom Web services gateway (TWSG), exposing the rich IMS services to the SOA world in an efficient, secured and manageable manner.
