World Class Standards 2 ETSI Role in testing IMS interoperability is a key issue for boosting IMS (IP Multimedia Subsystem) roll-out and more specifically network interconnection between operators. Only via thorough testing in practical scenarios can operators ensure operational excellence in a multi-vendor and multi- provider environment. IMS comprises a set of specifications designed to enable network operators to implement IP-based networks that can carry services for both fixed and mobile customers simultaneously. 2
World Class Standards 3 ETSI Role in testing IMS was developed originally in the mobile world (specifically in the specifications created by the 3rd Generation Partnership Project, 3GPP), and was adopted for fixed networks by ETSIs TISPAN Technical Committee (Telecoms & Internet Converged Services & Protocols for Advanced Networks). Advanced communications over the next generation network will only be delivered if those same networks can interconnect. 3
World Class Standards 4 ETSI Role in testing Testing support to all Technical Bodies early in the process Interoperability is best achieved when it is designed from the beginning and not bolted-on at the end ETSI is recognized as world leader for Testing and Interoperability Validation of Standards through Plugtests TM for 10 years Development of Test Specifications for over 20 years ETSI is between Standardization and industry Interoperability and conformance together Testing methodology TTCN3 and tool prototypes 4
World Class Standards 55 ETSI TC INT (IMS Network Testing) ETSI TC INT IMS Inter-OP & Interconnect. Test specs & events Technical Stream Industrilal Stream Fora and Organization Dealing with IMS IOP Demonstrations
World Class Standards 6 TC INT (IMS Network Testing) 3 IMS Interoperability Events IMS Interoperability and Conformance Test Specifications Published 4th IMS Interoperability Event is planned for 12-19 November 2010, Sophia Antipolis in ETSI
World Class Standards 7 TC INT (IMS Network Testing) Technical scope 3GPP Release 8 Interworking between IMS Core and AS for RCS services (this on request from GSMA RCS IOT group) Continue basic call, MMTel, hold/resume, topology hiding, IMS roaming testing Continue IMS to legacy PSTN/PLMN tests (add focus on Mg/Mj) Testing with IPv6
World Class Standards 8 The awareness of on-going testing activities Knowledge about test activities will give your company the right directions Participating to PlugtestsTM events will get your company in the right Place Participants to Plugtest have evaluated experience comparable to more than 6 months testing Call For Papers has been issued (CL 2761) Call for Articles for an ETSI Book on Success Stories in Validation and Testing
World Class Standards 9 The reuse of test specifications and results May sound like the re- invention of the wheel Test Specification are publicly available Test results can be get by participating to PlugtestTM, where in any case Finale test report is produced
World Class Standards 10 Using publicly available test specification means To use validated test specification To provide more feedback to the relevant 3GPP TSG To shorten Time to market.
World Class Standards IMS, from Standards to Practice -Technical Challenges for New Service Opportunities Comparison of advantages and drawbacks of the IMS model compared to the classical NGN New service opportunities and bringing services to the network quickly The importance of standardisation and standards Service options in a converged environment and example use cases Roland Schott, Project Manager, Technology Engineering Centre, Deutsche Telekom, Germany 11
World Class Standards Will the EPC make IMS obsolete in NGMNs? Understanding the role of the EPC (Evolved Packet Core) in the NGMN / 3GPP EPS (Evolved Packet System) architecture Key EPC architecture and functional capabilities Comparing EPC and IMS architectures and capabilities Why IMS: Investigating relevant NGMN applications and the needed platform support Learning on EPC potentialities – Experiences from the OpenEPC Testbed (www.openepc.net) Prof. T. Magedanz, TU Berlin / Fraunhofer FOKUS, Germany 12
