III. Internal Audit Function in UNIDO Nature and scope of the function 5. (...) Synergies with evaluation function 26. Notwithstanding the different roles and the different nature of the three functions of EIO (internal audit, evaluation, and investigation), there are commonalities and opportunities for synergies, particularly between the internal audit and evaluation functions. The work plans of the internal audit function and the evaluation function shall generally be reconciled to supplement each other and to avoid any unnecessary duplication or overlap.

New Functions to provide mobility management were identified as Home Location Function (HLF), Visitor Location Function (VLF), Authentication Function (AuF) and Inter-working Function (IWF). Also respective H.323 Mobility Annex H contributors introduced their documents, as listed in section 2 above, a number of requirements were identified for User, Terminal and Service Mobility capabilities: · The Mobility Management Functional Entities needed to provide the H.323 Mobility Management are Home Location Function (HLF), Visitor Location Function (VLF), Authentication Functions (AuF) and Inter-working Function (IWF) which reside above the IP layer shown in figure1. 2 Reference Need TEXT 2.1 Abbreviations Need TEXT 3 Definitions User: A person or other entity authorized by a subscriber to use some or all of the services subscribed to by that subscriber.

Although the proposed NGN control functional architecture neither identifies all functionalities required for the support of mobility/nomadism across diverse access networks nor proposes functions to ensure end-to-end QoS across multiple network domains, it is expected that future versions of the proposed baseline NGN control architecture would be enhanced to accommodate these widely recognized NGN features. (...) The NGN 2004 Project definition currently identifies the following areas · General framework model · Functional architecture model · End-to-end Quality of service · Service platforms (including APIs) · Network Management · Security It was noted that SG11 would be involved in Functional architecture modelling through the development of the Control plane functional architecture, in the Service/application platforms through the study of the signalling/control requirements and protocols/APIs, and in the definition of E2E QoS functional signalling requirements. Further, a domain of Signalling and Control functions and protocols should also be identified. 3 Highlights of the discussion There is a need from ITU-T Sector Members to progress work on NGN, particularly in the areas of Control functional architectures, signalling functional requirements and control protocols.
