[H.323 Mobility:] Trouble getting into the teleconference
by Jaakko Sundquist 09 May '00

09 May '00

Hi folks, I do not seem to be able to connect to the teleconference (the line is busy). I'll keep trying, but if I am not successful, I' afraid we'll need to postpone my introduction of the new draft to Osaka, sorry. ------------------------------------------------ Jaakko Sundquist * +358 50 3598281 * Audere est Facere! jaakko.sundquist(a)nokia.com * ------------------------------------------------ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ For help on this mail list, send "HELP ITU-SG16" in a message to listserv(a)mailbag.intel.com

Re: [H.323 Mobility:] A new editor's draft H.323 Annex H
by Roy, Radhika R, ALARC 09 May '00

09 May '00

Hi, Jaakko: 1. Home/Visited/Target/Visiting Network Address A quick reply related to your comment about mobile IP. The mobile IP cannot do the job of H.323 in the application layer deals with multimedia: audio, video, and/or video. However, if hooks are already there in the H.323 layer, only then mobile IP or other methods as appropriate can be used in the lower layer (e.g., IP, ATM) to do the job. So, the abstraction of home/visiting/foreign/target network address (or NPoA) should be there in the H.323 application layer. I hope that this will clarify the FUNDAMENTAL points of mobility management that AT&T contributions have explained. 2. GK Discovery MGA is another alternative option for the GK discovery. It is also very efficient when compared to the GRQ mechanisms. MGA is an OPTION, not mandatory. If some people do NOT like this, they may use the GRQ messages if they feel they are happy with it in the cellular environment. AT&T does NOT like to use the inefficient GRQ messages. 3. Centralized/Distributed HLFs AT&T contributions show message flows for all configurations of HLFs: Centralized and Distributed. The contributions show that it is the same messages that used for all cases. 4. Location_Req You are now using NEW messages location_req messages for mobility messages. AT&T contributions propose the new messages like mobility binding updates. You are requested to look into these contributions instead of going too. 5. Communications between HLFs for inter-domain communications. AT&T contributions show that this is NOT the scope of H.323. It is a protocol between the servers. This is nothing to do with the H.323 protocol. The same is true for directory server to directory server protocol, billing server to the billing server protocol, etc. 6. Other comments We will discuss in the conf call and Osaka. Best regards, Radhika R.

Hi, Jaakko: Thanks for providing your thoughts known to all of us. I appreciate this because you taken a step to make a progress assuming that this will help us. I have no problems to work in this fashion if everyone agrees with this process. The only thing that I have to do is to bring contributions with reference to the draft that you have provided. I can say clearly where things to be added, modified, and/or deleted. You can also include texts from the contributions showing agreement (and differences with editor's notes) in the Rapporteur contribution. I completely agree with you that we need to make a rapid progress. If everyone agrees with the process that you have taken, I will bring contributions accordingly so that you can clearly see where things (what text, figures, etc.) need to be added, modified, and/or deleted.

If you remember, we had a discussion about the way we will continue the Annex H work in the last teleconference. Since we have achieved almost nothing since the Geneva meeting I thought it would be a better idea if I produced a draft of the annex including my thoughts (of course taking into consideration the discussions that we have had) of how it should look like and you as well as anyone else could make your contributions against that. This idea also seemed to gain some support. > > Let me explain. > > You have two roles to play: First as an editor to reflect > what has been > agreed upon by the members based on contributions.

Quote from the first page of the draft: "NOTE: None of the changes, that are made to this document after the previous acceptance of changes (i.e. all changes that are highlighted when the MS-Word highlight changes option is on), are accepted by the members of the mobility ad hoc group." As I said above, I'm hoping that this kind of working method of me producing the draft annex and all of you making your contributions against that will make our progress faster. Unfortunately I was not able to bring the draft forward any earlier, which of course makes it harder (if not impossible) for you to make your contributions for the Osaka meeting against the draft directly. However, I do think that we can work in Osaka in a more systematic manner and perhaps even have some results. > > Section 4: > > I guess that you have one contribution showing these figures > 2 through 7 > (there is no reference - I see a similarity- am I correct?).

These figures are the same as in my contribution MTD-011b, which was not discussed in the teleconference because of lack of time. MTD-011b was based on the earlier contribution MTD-011 and the discussions we had about it in the first teleconference after the Geneva meeting. I thought that it is very important that we clearly explain what is meant by a scenario and what kind of scenarios we might consider in the H.323 mobility work. > > In fact, we discussed about your earlier contribution where > we have agreed > that we will start from all H.323 scenarios: First, > intra-zone, inter-zone, > and inter-domain scenarios. This is exactly why the figures are there. They explain what is really meant by the all-H.323 scenario (and of course the other scenarios as well). I have also added a statement to the scope stating that we will initately focus on the all-H.323 scdenario. Furthermore, the concept of the scenario was (nor is) supposed to include any reference to Intra-zone, Inter-zone or Inter-domain (this is actually the reason, why I thought that the MTD-011 needed to be re-written, it lead to a confusion about the meaning of scenario), so I see that it really is necessary to clearly explain the scenario concept in order to avoid this kind of misunderstandings. > > For inter-working between H.323 and non-mobile scenarios, > there are many > possible scenarios and we may not address in this document > for now for the > sake of time.

(I believe that at least Intel is going to propose some changes to it in Osaka). I do not think we need to put in any comments saying that. Furthermore, could you explain what you mean by saying that the figure is just a placeholder for the ongoing discussions?

I do not think that chapter 8 is even nearly complete, but since we have had quite a lot of discussion going on around the concept of Virtual Home Environment (especially with Ericsson), I wanted to add something that would explain the difference between these two distinct concepts. I would really appreciate, if someone would bring in contributions to refine this chapter. > > Did you submit an outline of your draft to be approved?

I have tried to gather the issues that I think we have more or less agreed on in our discussions with regards to this chapter. I have made some new names for certain concepts and for some parts I have made my own suggestions (mainly the information flows).

Call establishment I think this is exactly what I have done. The problem with the terms Intra-zone, Inter-zone and Inter-domain is that I do not know what you exactly mean by them. In the previous H.323 standards the division has been easy, because there is always a call involved and the division is made based on the relative locations of the participants of the call. In Annex H, however, it is often needed to contact e.g. different domains even though the call might actually be an Intra-zone call. I have introduced the ideas of Location updating procedures and related to that the Intra/Inter-zone/domain location changes as well as Call related MM procedures that can be divided into Intra(Inter-zone/domain call cases to clarify the categorization. > > AT&T and Alctel contributions are there and these contributions were > discussed.

These contributions were discussed, but I do not remember having an agreement on almost anything in those contributions. The only thing we almost agreed on in the AT&T contribution was the figure illustrating the zone, its relation to the funtional entities and the NPoAs. This figure has been used as a "model" for the figures 10 - 13 in the draft annex. > Section 9.1.1: > > Like home domain, AT&T contribution has provided the detail > description of > home GK/zone from a user point.

With regards to the home GK, I am considering that it may be a good concept to introduce for some purposes (mainly because of GK discovery issues and the Virtual Home Environment concept), but I have not yet introduced in the draft, because I want to have a clearer picture of how the concept would be used. I certainly do not like the idea of always having to contact the home GK in order to be able to use the H.323 services, nor do I like having to contact the HLF through the (home) GK. In other words I am willing to add the concept as soon as we have agreed on the semantics of it. I still do not see the merit of the home NPoA concept, I do not think it adds anything that could not be achieved by using e.g. mobile IP. > > I would expect, like visiting/visited domain, the concept of > visiting/visited/target network address should be taken as a > part of it. > Without this, the mobility management will almost be > MEANINGLESS because the > trivial mobility management keeping some addresses in a database like > VLFs/HLFs do not help the service providers and the mobility > management > through re-registration is already there in H.323, and no new > standard work > is needed for extending the so called VLFs and HLFs databases. I do not think it is meaningless to define an organized way of keeping track of the Users' location in the network. That in my opinion is NOT present in H.323. It does not mean that these mobility management features have to be overly complicated, in fact I would prefer as simple (or trivial) solution as possible. If and when we get this trivial issue settled we can perhaps add more features to the Mobility Management. > > Figure 11 shows that the inter-zone mobility management is > maintained using > the single HLF.

As I have stated in some earlier emails to the list, I do think that it is necessary to regard that only one logical HLF holds the location information of a particular User. This database could be distributed in some way unknown to the H.323 system and we could even define a method for enabling the HLF to have multiple network addresses (i.e. multiple "locations" in the network where it could be accessed), but I do not think that we should try to define a way to distribute the HLF database in the network (and that I think is what you are suggesting by having multple alternative HLFs for a User). > > Figure 12 shows that a single VLF is communicating with > multiple HLFs. Which > contributions do you refer to? I have always assumed this as a possibility, but you are right, it has not been exactly stated in any contribution before, so I guess I am contributing it now. It is of course possible to have the VLF only be in contact with one HLF, if that is what we want. > > Figure 13 shows that HLFs are communicating between the > domains?

When the Hinter reference point was added to the architecture figure, I thought that we made the assumption that Inter-domain communications between the VLFs and HLFs are possible. If we want to remove that possibility, I'm more than happy to agree. In fact I remember even making a contribution (sometime in the autumn) suggesting that BEs are used in the Inter-domain communications. > > Are you "pushing" for some something (or am I missing > something)?

Actually, personally I quite like your idea of the MGA message (or something similar), but it seemed to create quite a lot of opposition, when we discussed it over the phone (I think there were claims that in fact the MGA would NOT be a more efficient method), so I did not add it. This is something that I think we need to discuss in Osaka. > > Section 9.5: > > Again, I like to know which contributions you are referring to? > > Figures 15, 16, 17, 18, and 19 show that, as if, the protocol is > "hard-wired" for the centralized HLF configuration.

Re: [Robustness] End to End Acknowledgement Contribution
by Sasha Ruditsky 09 May '00

09 May '00

Tim I just went through the "Message lost" list and I believe that at least some of the messages in the list may be lost without causing any problem. Let start from the *********Communication Mode Command. This command used to ask remote terminal to use new set of outgoing channels. As result the remote terminal will close and/or open new ones. The terminal does this using explicit logical channel signaling. So the MC that sent the communication mode command actually has the acknowledgement for the command. The communication mode command by itself does not cause H.245 state change and may be retransmitted without problem, so the MC that is uncertain whether the message has been delivered or not may always resend it. *********Multipoint Mode Command Multipoint Mode Command is almost the same it actually causes the terminal to comply with the "requestMode"s. The only problem ,I may think about, that may be caused by lost Multipoint Mode Command is request Mode rejection. When this happens MC may safely retransmit Multipoint Mode Command and try request Mode again. *********RELEASE COMPLETE This is correct that this message has no acknowledge and I believe that the reason for this is that it is almost always acknowledge by itself. It is in most cases the last message in the end to end message sequence. In case we have H.245 in the call this sequence may be started by the end session command exchange. For call independent signaling connections procedures in H.450 the RELEASE COMPLETE message always or almost always goes immediately after some other end to end message in opposite direction so may be defined acknowledge to it. Even if such definition is impossible I cannot see the problem that may caused by lost RELEASE COMPLETE message in this case. The real problem with lost RELEASE COMPLETE message may be in the case of fast start signaling. For this specific case we need to find solution. The possible solutions may be: Using RELEASE message (as you proposing) Defining special "End Of Fast Start" message (this does not necessarily requires new syntax let say Facility with empty fast start sequence may be defined to do this). Using STATUS exchange for fast start calls (as we proposing) Preventing usage of fast start on robust system. *********User Input Indication The behavior of the system that receives User Input Indication is not defined in standard. I believe that the recovery from the loss of the message should not be defined in standard too. In addition User Input Indication defined in the way that assumes sending DTMF digits to PSTN where they may be lost even H.323 segment delivers them reliably. In some cases, especially when there is different mechanism to acknowledge User Input Indication delivery, controlling User Input Indication resend on the protocol level may even cause problems. For example there are games where the video/audio streams are broadcasted by TV and the player controls the game over telephone line using DTMF. In case system does not respond properly player tries to correct this sending new DTMFs. If in addition the system tries to resend the lost ones the behavior may be funny. The PSTN systems that currently exist use DTMF to deliver user input. DTMF is by definition is something that may be lost and I believe that there are no mechanisms to acknowledge DTMF that are built into PSTN. So I assume that there are application level methods to solve the problem. What I want to say is that recovery from User Input Indication lost is the application problem and the level and method of recovery shall be defined by the application. *********************************************** Alexander(Sasha) Ruditsky RADVision Ltd. 24 Raul Wallenberg St. Tel Aviv 69719 Israel Tel: +972-3-645-5220 Fax: +972-3-645-6464 Direct: +972-3-645-5273 sasha(a)radvision.rad.co.il *********************************************** -----Original Message----- From: Tim Chen [mailto:scc@TRILLIUM.COM] Sent: Tuesday, May 09, 2000 5:37 AM To: ITU-SG16(a)MAILBAG.INTEL.COM Subject: [Robustness] End to End Acknowledgement Contribution Hi, Please find attached our write-up on end to end acknowledgement.

H.248 Annex C Codepoint Information
by Tom-PT Taylor 08 May '00

08 May '00

H.248 Annex C is by concept derivative in nature -- it provides the means to reuse codepoints from a variety of other standards. As it currently stands, it reproduces these codepoints in the "Value" column. I am concerned that this could present a maintenance nightmare. It would make more sense to point the user to the specific reference in the other standard and leave it at that. Tom Taylor Phone and FAX: +1 613 736 0961 E-mail: taylor(a)nortelnetworks.com

Re: [H.323 Mobility:] On home concepts, etc.
by Roy, Radhika R, ALARC 08 May '00

08 May '00

Hi, Steve: I am really curious to se the detail of Ericsson's contribution. What I am worried about that the basic problems still remain the same whether we go via GKs (or HLFs). Now GKs and BEs have mechanisms in place if any information is not available to a GK (or BE) how to communicate with another one to resolve it. In view of many HLFs, I am afraid that we may to do the same with the HLFs all over again. Then the basic question comes: Why do we want to re-invent the wheel (assuming that a GK or BE will be able to do the job if we go via them because HLFs are sitting behind them). We will discuss when we see your contributions. Best regards, Radhika R.

Re: [H.323 Mobility:] A new editor's draft H.323 Annex H
by Roy, Radhika R, ALARC 08 May '00

08 May '00

Hi, Jaakko: I hope that you have been enjoying the ice-hockey.... I understand that the editor's draft is just a contribution for the upcoming tomorrow's conf call, not a draft for the Osaka meeting. I do not know which parts of your draft have been taken from the contributions that had been discussed and agreed. I have seen no reference to it. Or, have you made some educative guess from your side? Let me explain. You have two roles to play: First as an editor to reflect what has been agreed upon by the members based on contributions. Second, an individual from Nokia to agree or disagree. An editor must provide the draft that will reflect what has been agreed by the members based on contributions. However, as an individual from a company an editor may have differences. These differences can be reflected in the draft in two ways: 1. As an editor's note and 2. Even as an individual from Nokia (assuming that subsequent contributions will clarify this). I do not have enough time to provide all comments in writing. In brief, I have the following comments: Section 4: I guess that you have one contribution showing these figures 2 through 7 (there is no reference - I see a similarity- am I correct?). We never discussed this contribution in any conference call. How come that you have included all figures from your contribution that has not been discussed and agreed? In fact, we discussed about your earlier contribution where we have agreed that we will start from all H.323 scenarios: First, intra-zone, inter-zone, and inter-domain scenarios. For inter-working between H.323 and non-mobile scenarios, there are many possible scenarios and we may not address in this document for now for the sake of time. So far I re-collect, this has been the decision. Section 4 does NOT reflect this. Section 7: I like to see that there should be an editor's note that "Figure 8 will be revisited based on the extensions that will be made in H.323 to support mobility. This is just a place holder to provide references for the on-going discussion." Section 8: Which contributions your are referring here that we have agreed? I would request that people MUST bring contributions to define virtual home and service execution environment before an editor put any texts in it. Did you submit an outline of your draft to be approved? Section 9: Which contributions you are referring to? Did you have any outlines for this section that need to be approved? My understanding has been that we agreed that the mobility management will include: A. Intra-Zone, B. Inter-Zone, and C. Inter-Domain. In each case it will have the following: 1. GK discovery 2. Registration 3. Location update 4. Call establishment AT&T and Alctel contributions are there and these contributions were discussed. The outlines should follow these procedures to follow the text consistently. Now I am providing comments per sections that you have arranged although I do not agree with the outlines. Section 9.1.1: Like home domain, AT&T contribution has provided the detail description of home GK/zone from a user point. Accordingly, home network address (network point attachment) has been explained. In a given zone, a mobile may move from one NpoA to another. Like foreign (or visited/visiting/target) domain, AT&T contribution has also explained the foreign (or visited/visiting/target) network address (or NpoA). The subsequent emails have also been sent explaining the things. I would expect, like visiting/visited domain, the concept of visiting/visited/target network address should be taken as a part of it. Without this, the mobility management will almost be MEANINGLESS because the trivial mobility management keeping some addresses in a database like VLFs/HLFs do not help the service providers and the mobility management through re-registration is already there in H.323, and no new standard work is needed for extending the so called VLFs and HLFs databases. Figure 11 shows that the inter-zone mobility management is maintained using the single HLF. Which contributions you are referring to? Did we agree on this concept? AT&T contribution shows that it is an unacceptable proposition if we consider that there is a single HLF (as the protocol is "hard-wired" for a centralized HLF configuration)? Figure 12 shows that a single VLF is communicating with multiple HLFs. Which contributions do you refer to? Figure 13 shows that HLFs are communicating between the domains? Did you not see that we are NOT in sink with this approach because the questions have been raised that this approach might be "breaking" the H.323 standard? AT&T has also provided contributions regarding this (I guess that Alcatel's contribution also agrees with AT&T's contribution in this regard). Are you "pushing" for some something (or am I missing something)? If it is so, please bring contributions, we will be pleased to discuss. Section 9.2: Use of GRQ messages for the GK discovery is NOT new in H.323. It is already a standard. A reference to the existing H.323 standard is enough. However, the fundamental question has been that GRQ messages are NOT efficient for the GK discovery in the cellular environment. AT&T contributions have provided an alternative solution using the MGA message for the GK discovery. So, the use of GRQ messages are INEFFICIENT for the GK discovery. So, it is NOT acceptable in the highly mobile environment. Section 9.5: Again, I like to know which contributions you are referring to? Figures 15, 16, 17, 18, and 19 show that, as if, the protocol is "hard-wired" for the centralized HLF configuration. AT&T contributions do not assume this. We have NOT accepted this notion. So, the basic question: Why do you want to include the material where there are no contributions and no agreement? There are fundamental flows the way you have shown all information flows. Let me cite few examples: You have shown that LRQ messages are sent from the GK to the VLF and/or HLF. Why do you think so? Did you not see that we have NOT even agreed with this in the last conference call and via emails? AT&T contributions have used NEW mobility management messages. We have serious problems if we use LRQ messages like this. That is why, AT&T has provided a contribution APC-1769. Considering the comments provided above, all texts provided in your contribution need a COMPLETE re-writing of the document. I understand the difficulty with the job as an editor. I appreciate your efforts. However, there are some norms that an editor has to follow: Contributions and Agreement made. If editors have their opinions, they can bring separate company contributions (NOT as Rapporteur contributions). Hope to discuss the same in tomorrow's conf call. I am also curious to know which the team won the ice-hockey..... Best regards, Radhika R.
