Dana,Read your comments and I think you hit a lot of very good points.
I think I could break down your comments into four categories.
* those that there already exists capable IETF protocols (example: use of Mobile IP, SIP and HTTP to support mobility management)
* those that there are IETF protocols that need work in order to support wireless but appear to be going in the right direction (examples: caching registration, or the work on QoS for wireless, or maintaining context during hand-offs)
* those where the requirements are not clear, and where a question exists as to why a certain IETF protocol would or would not provide a viable solution to the underlying problem. (examples: why is layer 3 paging needed when layer 2 does the job, or why can't a gateway that converts IS-41/GSM Map to radius not work, or why does the terminal need authentication if the user is already authenticated).
* those where the requirements are not clear at all. (example: what is a session, or several cases where its not clear how the legacy telephone supports a feature, and should we care if it is only a legacy telephone requirement).
I think areas that might be raised as issues in the BoF would be those in the second and third, which raise questions that need comment, discussions that might lead to creating a working group to address. Of course the first category might generate some comment from operators and the traditional vendors.
Thanks,
Dave...
