Dear Q.11-14/16 experts,

I have uploaded the Torino meeting report of Q.12-14/16 group as APC-1485 at the following place:

ftp://standard.pictel.com/avc-site/Incoming/1485.zip or http://standard.pictel.com/ftp/avc-site/Incoming/1485.zip

This is an integration of TD-07, 12, 18, 19 and other TDs.

Please review it and return your comments, if any, by 11 December 1998. Then I will move it to /9811_Tor directory with confirmed status and send copies to Mr. Tosco and Mr. Bigi.

Attached please find Section 7.1 recording the IMT-2000 related discussion and conclusion. I have added the alternative way of describing the requirements to the IMT-2000 network. Please Mr. Wenger and other interested members review the second last paragraph and return your advice to make it correct.

Best regards,

Sakae OKUBO (Mr.) *********************************************************** Waseda Research Center Telecommunications Advancement Organization of Japan (TAO) 5th Floor, Nishi-Waseda Bldg. 1-21-1 Nishi-Waseda, Shinjuku-ku, Tokyo 169-0051 Japan Tel: +81 3 5286 3830 Fax: +81 3 5287 7287 e-mail: okubo@giti.or.jp ***********************************************************

7.1 Future direction (APC-1458, 1459, 1460)

APC-1458 and 1459 (TAO) presented high level requirements for the future system H.32L and discussed some technical aspects. APC-1460 (NTT DoCoMo) discussed multimedia terminals on IMT-2000 network proposing that H.324 and H.323 be used for circuit switched service and packet switched service, respectively.

A joint session among Q.11-14/16 addressed the appropriate multimedia systems for IMT-2000 in the context of currently conceptual future system H.32L. A crucial question for our multimedia communication systems is what type(s) of network service would prevail in the future including those of IMT-2000.

After some discussion, the meeting concluded that the multimedia system (including but not limited to voice only) for IMT-2000 could not be singled out, rather the approach taken so far should be applied to IMT-2000 as well, resulting in systems optimized to the given network characteristics such as H.323 and H.324/M.

Based on this discussion, the meeting attempted to return a liaison response to ITU-T TG8/1 and ITU-T SG11/Q.23 as in TD-14. However, due to lack of quantitative requirement description which was thought essential for sending the liaison, the meeting concluded to attach TD-14 to this report as a basis for further study toward the next meeting (Annex 5 to this report). An alternative way of presenting the requirements was proposed; to describe the performance of each H.300-series system when the given network characteristics (such as bit rate) are minimum and expected performance when the network characteristics are beyond the minimum.

Contributions are solicited.
