SIP-IMS CONFORMANCE TESTING STANDARDIZATION WORK PLAN VICE-CHAIRMAN OF ITU-T SG11 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 QoS/QoE)

DESCRIPTION OF ITU-T SG11 STANDARDIZATION ACTIVITIES ON SIP-IMS  To develop the living list of ITU-T standards on SIP- IMS 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 SIP- IMS 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 SIP- IMS 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 SG11 activity and initiate the relevant ITU test event
