SIPIMS CONFORMANCE TESTING STANDARDIZATION WORK PLAN VICECHAIRMAN OF

SIP-IMS CONFORMANCE TESTING STANDARDIZATION WORK PLAN VICE-CHAIRMAN OF ITU-T SG 11 MARTIN BRAND

BACKGROUND § Most telecom operators have already implemented the IMS platform, connecting their customer’s Terminal Equipment (TE) through SIP-IMS protocol § Different implementation of SIP-IMS protocols can require additional operator’s efforts (budgets) to adapt TE to the installed IMS platform § The roaming services will be not available among operators due to an incompliance of protocol’s realization § Most telecom operators refer to ITU-T Recommendations in case of debatable issues with partner (operator – issues with interconnection, vendor – issues with equipment)

OBJECTIVES § To collect all standards on SIP-IMS profile in ITU-T and amend it with missing standards § To establish the conformity assessment of SIP-IMS profile which may be used by telecom operator for testing an equipment based on SIP-IMS profile § To create a list of TEs based on SIP-IMS profile which comply with ITU-T Recommendations (e. g. signalling protocol, voice Qo. S/Qo. E)

DESCRIPTION OF ITU-T SG 11 STANDARDIZATION ACTIVITIES ON SIP-IMS § To develop the living list of ITU-T standards on SIPIMS profile which can be used for conformity testing of user and network equipment (the existing standards on SIP-IMS of other SDOs will be endorsed if needed) § To develop the missing standards (e. g. requirements, test specifications, use cases, etc. ) § To start the ITU pilot project for conformity assessment of the equipment which is based on SIPIMS profile (Testing Laboratory and other interested parties are invited)

ACTIONS • Define the missing requirements for Network side and User side for SIP-IMS profile (for basic call and supplementary services, ETSI standards) • Develop the missing conformance tests specifications for SIPIMS profile • Develop the conformance tests specifications for Integrated Access Devices (IAD) • Fixed and mobile operators are invited to establish the alliance aiming to use ITU-T Recommendations on SIP-IMS profile as a basic requirement for user's equipment (UE) • Telecom operators are invited to join this SG 11 activity and initiate the relevant ITU test event
