The attached document is about some proposed revises to H.248.14 Inactivity Timer Package. It is intended to ITU-T SG16 Rapporteur Meeting on Melbourne (Feb-Mar 2005), but maybe no the final contribution. The delay contribution with the same subject (D0021) had been discussed in the ITU-T SG16 Plenary Meeting on Geneva (Nov 2004). However there were some misunderstanding for that contribution had not been clarified adequately then. So I renewed the document to give more detail about the essentiality of these revises. Please pay attention to the section "Problem Discussion" for the object secenario we aim to resolve, and the chapter "Conclusion" for the detailed revises we proposed. I issue the document inside this mail-list in order to gain your expert advices as more as possible. Any advice or comment from anyone of you is highly appreciated. Thank you very much!
