This is called the WAP solution, already done but it is still two separate networks (MSC-CS and PDN) routed/ split out by a DSU from the BSC. And it does not address the fixed Internet PC or any PSTN/ISDN interworking.
We are looking at the H.323 mobility at the appilation layer within the approriate woking groups.
I feel a mobile IP debate is in the starts here but, We are looking at the H.323 mobility at the appilation layer within the approriate woking group. What the IETF needs to address is how mobile IP interworks with Mobility whether is H.323, GSM, PLNM or otherwise..
I don't think any of what is being discussed for Annex H is necessary to achieve this.
What being discussed here is, we are looking at the H.323 mobility from the appilation layer.

Hi, all, Barry Aronson's comment seems to make a lot of sense to me. I am new to the H.323 group, but I've been reading the email correspondences here for quite a while. May I ask a few dumb questions, and please correct me and elighten me if I am wrong? Question: Consider the wireless case, isn't that H.323M is going to be used over some wireless network (e.g. 3G IMT2000 network)? If such network is already built to ensure that your data gets transmitted to you no matter you walk or drive from one zone to the other, why can't our H.323M terminal just sit at the handset and wait for our data get routed to us by the network? Or, why do we need to duplicate these functions that are already provided, and should be provided by the network layer? Maybe, all we have to do is to make sure we know the data is from the same entity when it changes its attaching point, since each H.323 entity is identified by the LAN address (H.323 7.1.1). A simple extension of assigning a temporary ID number to each entity or to each conference can solve that. Please enlighten if there is any special compelling reason that I might have overlooked for duplicating an entire mobile network functionality within H.323. Thanks in advance.
