Slide no. 2  =====!"§!“!Nova§ Study Group 10 mandate Responsible for technical languages, the methods for their usage and other issues related to the software aspects of telecommunication systems. Studies on modelling, specification and description techniques and on other software aspects will be developed in line with the requirements of and in co- operation with the relevant other Study Groups (4,7,11,13,16). SG10 is Lead Study Group on Languages and Description Techniques within ITU-T SG 10 Policy: Strong coupling with industrial needs and use

Slide no. 7  =====!"§!“!Nova§ Question 3: Software Platforms and Middleware for the Telecom Domain Framework: identify and specify the inter-domain reference points for the purpose of testing the associated specifications Generic set of object services to support the distributed processing environment for the telecommunication domain Techniques and functions to support the management of software infrastructures, object services and applications Profile set for the DPE and their use to accommodate different sets of requirements. Generic requirements on the DPE are expressed in Z.600 Investigation: need for QoS by the DPE

Slide no. 8  =====!"§!“!Nova§ Key messages Work is planned in TINA-relevant areas for the period ITU-T is fast: New ITU-T procedures, e.g. the Alternative Approval Procedure permit fast approval of Recommendations However, clear requirements exist for work to be successful o Support and input from experts o Support from the industry for the implementation of concepts Study Group 10 policy is to work only on issues for which there is industrial need or requirements from the standards bodies themselves, and in general tool support commitment
