ETSI INT IMS/EPC Interoperability Standardisation: Motivation, Roadmap & First Results

INT = IMS Network Testing. ETSI INT website here. More details below the presentation:

This was presented by Giulio Maggiore, Telecom Italia, ETSI TC INT Chairman in the 2nd FOKUS FUSECO Forum 2011, Berlin 17-18 Nov. 2011

From the ETSI leaflet (note that this is quite old information but still on the ETSI website here):

IMS interoperability is a key issue for boosting IMS (IP Multimedia Subsystem) roll-out and more specifically network interconnection between operators. Only through 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.

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 ETSI’s TISPAN Technical Committee (Telecoms & Internet Converged Services & Protocols for Advanced Networks).

However this promise of advanced communications over the next generation network will only be delivered if those same networks can interconnect.

ETSI’s Technical Committee INT: IMS Network Testing

ETSI is bridging the existing gap between 3GPP IMS Core Network standards and the initial industry IMS implementations through the organization of IMS interoperability events in connection with ETSI’s Centre for Testing & Interoperability (CTI) and Plugtests™ interoperability testing service.

Our Technical Committee for IMS Network Testing (TC INT) is actively establishing close contact with a number of industry fora and organizations dealing with IMS interoperability, including 3GPP, GSMA, MSF (Multi Service Forum), IMS Forum and the ITU-T. TC INT develops IMS test specification according to conformance, network integration and interoperability testing methodologies. Other ongoing work includes development of tests for Supplementary Services based on regulatory requirements and IMS tests with legacy networks (e.g. SIP-I).

ETSI has already held two IMS interoperability events. The first examined interconnection aspects of 3GPP IMS Release 6, including such issues as basic call on the Mw interface. The second event had a wider scope that included the testing of 3GPP IMS Release 7 interworking, roaming, border control, and integration of application servers executing selected Multimedia Telephony supplementary services.

Future ETSI activities and events will go even deeper towards bridging 3GPP IMS standards and industry implementations. These will include the organization of further IMS interoperability events designed to boost the roll-out and take-off of IMS services and operators’ network interconnections.
