Re: Mob ad hoc group progress
by Jaakko Sundquist 05 Apr '00

05 Apr '00

Hi all, Once again there seems to be quite a lot of confusion about the terms we are using. First of all, we did not make it altogether clear in the last teleconference, what is meant by a scenario. My contribution on the issue tried to group both the "call scenarios" and the "location management scenarios" into one set of scenarios. We did notice during the teleconference that this was not an adequate approach and now some of the problems occuring in this email discussion reflect that. For … [View More]example, when Radhika is talking about starting with the intra-zone scenario, I'm not quite sure what he is meaning. I understand that the "call scenario" he is talking about, is the one in which both terminals are registered to the same gatekeeper. However, this "call scenario" in itself does not really bring anything new to H.323 unless there is something that we need to address with the "location management scenarios". Now, while the "call scenario" does indeed fall into the category of intra-zone communications, the "location management scenario" for finding the address of the B-subscriber of the call might not, i.e. the VLF and HLF that need to be contacted may not be located in the same zone or even domain. Furthermore, we haven't even decided that the VLF and HLF should be a part of any zone. I know that most of us actually think that the VLF is always located with the gatekeeper, but so far we haven't made that decision and certainly we haven't coupled the HLF functionality always with the gatekeeper. Thus it is quite unclear what is meant by intra-zone "location management scenarios" and I would suggest that we do not even try to define this term. Instead intra vs inter domain "location management scenarios" make much more sence. (Note that I'm using the terms "call scenario" and "location management scenario" quite freely here. If we want to use such terms, they definitely must be clearly defined.) Also, I would like to point out that talking about intra-zone, inter-zone, etc. scenarios, is actually not what was originally meant by a scenario. The idea to introduce scenarios into the H.323 Mobility work came from Tiphon, where 5 different scenarios are identified. These scenarios do not take into account, whether the call (or other connection) takes place inside one zone (intra-zone), between two zones (inter-zone) or between domains (inter-domain). The scenarios in Tiphon simply state which network types are involved in the connection, e.g. Tiphon scenario 1 is the VoIP-to-SCN scenario, Tiphon scenario 2 is the SCN-to-VoIP scenario, etc. These were the kind of scenarios I thought we were trying to identify in the last teleconference. Of cource, each of this kind of scenarios may involve calls that are intra-zone, inter-zone or inter-domain calls, but we shouldn't call (no pun intended) these different call models as scenarios. We have now chosen the all-H.323 scenario as the first one to examine (although we didn't even know what it means). In my mind this means that: * We only examine call cases, in which no gateways are included. * We examine gatekeeper discovery, registration and location updating cases, in which the user is accessing the H.323 system either in his/her home network (e.g. domain) or a visited network (e.g. domain). * We examine call establishment and call release cases, in which the A-subscriber is either in his/her home network (domain) or in a visited network (domain). * We examine call establishment and call release cases, in which the B-subscriber is either in his/her home network (domain) or in a visited network (domain). Note that the call can be intra-zone, inter-zone or inter-domain irrespective of whether the B-subscriber is in home or visited network. * We examine mid-call scenarios (e.g. some supplementary services), in which the user (either A- or B-subscriber) is either in his/her home network or in a visited network. * In the context of H.323 Annex H we do not address the inteworking functionalities (IWFs) between the HLF/VLF/AuF and some non-H.323 network, unless some other document (such as H.246 Annex E) proposes additions to H.323 Annex H. (Note that, when we start work on some other scenarios in the future, we probably will have to take the IWFs into account.) Other issues that need to be addressed are at least the definitions for the home/visited network/domain/zone/gatekeeper, because it seems to me that some members are already using some of these terms in ways that already point to certain solutions, on which we have not yet agreed. I will try to work out a suitable contribution for the next teleconference to clarify these issues properly. If you have some comments to this mail, please respond. I know that this is a long posting with quite a lot of issues in it and I'm sure that I haven't explained myself too clearly in all parts of it, so please ask. ------------------------------------------------ Jaakko Sundquist * +358 50 3598281 * Audere est Facere! jaakko.sundquist(a)nokia.com * ------------------------------------------------ -----Original Message----- From: EXT Roy, Radhika R, ALARC [mailto:rrroy@ATT.COM] Sent: 04.

Re: Force remote to start H.245 session?
by Paul Long 04 Apr '00

04 Apr '00

Chris, I think you see my point, then. Now that I think about it, an EP _is_ required to at least send its TCS, if it has not already, if it receives an H.245 request message. Specifically, it cannot send the TCSAck until it has sent its own TCS, according to the following: 8.2/H.323v3: "Endpoint system capabilities are exchanged by transmission of the H.245 terminalCapabilitySet message. This capability message shall be the first H.245 message sent." And then there's the following. I think … [View More]it means that if an EP receives TCS without already having sent TCS itself, it shall do so now. Is that your understanding? 8.2/H.323v3: "An endpoint which receives a terminalCapabilitySet message from a peer prior to initiating capabilities exchange shall respond as required by 6.2.8.1, and should initiate and successfully complete capabilities exchange with that peer prior to initiating any other procedure." So if an EP initiates H.245 procedures, the remote is forced to also perform H.245 procedures. Okay, that's what I was looking for. Maybe it just means that it has to perform the cap exchange. You know, both sides don't really need to initiate the MSD. It's enough that the side that first wanted to use H.245 procedures has performed it, so TCS alone is enough of a prelude to get the H.245 session up and running. Do you think this needs clarification text? Paul Long Smith Micro Software, Inc. -----Original Message----- From: Chris Wayman Purvis [mailto:cwp@isdn-comms.co.uk] Sent: Monday, April 03, 2000 8:00 AM To: Paul Long Subject: Re: Force remote to start H.245 session? Paul, First of all, sorry for the fact that this seems to be a week-old mail I'm finally responding to... I may have misunderstood, but I don't understand why this is necessary. If both endpoints have expressed willingness to use tunnelled H.245, why can an endpoint not simply start sending H.245 messages (of COURSE starting with TCS, and potentially tunnelled in purpose-built FACILITY messages) when it wishes to start a tunnelled H.245 session? I would have thought that would be a pretty clear indication of intent to start a tunnelled H.245 session! FACILITY/reason=startH245 is required for separate H.245 connections because an endpoint may not know an address at its interlocutor to use to initiate an H.245 connection. This problem doesn't exist in tunnelled H.245, so I see no necessity for the extra interpretation! We may want some extra text specifying behaviour at the start of an H.245 session, to ensure that the destination of the initial tunnelled H.245 message actually does something constructive (sends a TCS) rather than non-constructive (merely Acking the TCS it's been sent and not advancing anything useful).
