F.MMCIP ^^^^^^^

1/ Section 2.6

As we have "multimedia conference service" in Section 2.9, I would suggest the following:

A type of multimedia conference service that utilizes networks for control and media transfer.

2/ Section 2.7, last sentence

As we may also use ALM (Application Layer Multicast) in the future, use of network transport multicast may not be an only solution. "may" instead of "should" would be more appropriate.

3/ Section 5, 2nd paragraph

"If there are two or more terminals, ..." I wonder if the number be "three or more" instead of "two ore more". The multimedia information control and exchange is needed also for the case where only two terminals are involved?

The multimedia information control and exchange isn¡¯t needed in fact, but in some cases, the multimedia information control and exchange still works. For example, three terminals in a five-endpoints conference leaves, but the conference still continues, the multimedia information control and exchange still is needed though only the two terminals in this conference.

4/ Section 5, 3 bullets

It looks multiple viewpoints are involved to get these three types of terminal: hardware/software, full/part time use, movable/fixed. Please sort them out.

following is the propositional modification text : There are two types of terminal: ¨C Hard terminal, which includes two sub-type of terminals: dedicated studios equipped for multimedia conferences, named special conference terminal; equipment only part-time used for teleconferencing, can be moved from here to there, named Portable Terminal ¨C Soft terminal, running on Computer

5/ Section 6.1, 2nd sentence

We need clarification here.

Since the "Voice/Video/Data Switch & Process function" is in the IP-based Network area, the multimedia path between the switch&process function and the right most User is understood to be IP. Does this mean that PSTN Access terminal is using IP over PSTN? It looks more realistic to me that the switch&process function has PSTN interface and the voice is ordinary analog one.

since the function of "Voice/Video/Data Switch & Process function" is mainly about media processing, so my suggestion to this problem is another ¡°gateway function¡± is added for the PSTN and IP transition, also for the mobile.

6/ Section 6.3

I would suggest to unify the function listing style as verb first.
