Otherwise, I'm sure that we can get a lot of good stuff from both 3GPP

selective.

klaus,
many years ago when i looked at ims, it placed lots of restrictions on
how request must be routed through the mace of proxies and what
information has to be transmitted between the proxies in order to be
able to bill the user many times by each participating operator. it
was
not possible to place a call without being registered first, call
someone on the internet, etc. i don't think that any of that has
changed. i thus got the impression that telco business model was in
fact built-in in the interface specifications.
