2The Problem Stated by Henry
Not counting I-D pages
3950 SIP pages, nebbich
- Just one 3GPP recommendation with the mighty
title - Digital cellular telecommunications system (Phase
2) Universal Mobile Telecommunications System
(UMTS) Signalling flows for the IP multimedia
call control based on Session Initiation Protocol
(SIP) and Session Description Protocol (SDP)
Stage 3 3GPP TS 24.228 version 5.14.0 Release 5 - features 715 pages
- ETSI TISPAN (dealing with IMSoFA) created over
2000 temporary documents in 2005 - Some say this is already pathological (S4)
IMSoFA IMS over Fixed Access (WiFi)
IMS Internet Monetisation System
4Systems Standards Stockholm Syndrome
- S4 - Systems Standards Stockholm Syndrome (John
Waclawsky, Mobile Wireless Group, Cisco BCR
June 2005) - The Stockholm Syndrome describes the behavior
of hostages. - The System Standards Stockholm Syndrome (S4)
describes the behavior of system standards
participants who, over time, become addicted to
technology complexity and hostages of group
thinking. - S4 applies specifically to systems standards
participants who suffer repeated exposure to cult
dogma contained in working group documents and
plenary presentations. - By the end of a week in captivity, Stockholm
Syndrome victims may resist rescue attempts, and
afterwards refuse to testify against their
captors. In system standards settings, S4 victims
have been known to resist innovation and even
refuse to compete against their competitors. - Recent incidents involving too much system
standards attendance have resulted in people
being captured by radical ITU-like factions known
as the 3GPP or 3GPP2. - This leads to the following

8The Future of Interconnection as seen by GSMA
(optional)
This is NOT the Internet
Note this
So much about IMS is NOT a Walled Garden
9Who will pay for this?
- The end-user the customer
- Will he?
- Not if he has a choice
10A Reminder
- The Internet is (or is intended to be) a network
without central intelligence gt The stupid
network (David S. Isenberg) - The Internet is based on the end-to-end principle
- Every user may reach any other user via the IP
address - All services may be offered anywhere and may be
accessed from everywhere - This is of course also valid for voice and other
communication services - VoIP (and other RTC services) is not necessarily
a service, it is an application - so no service
must be provided - Jon Peterson at the ITU-T/IETF NGN workshop in
Geneva May 2005 - If there is no service provided, you do not need
a service provider either.
11End Means End-User Customer
- BTW, who cares about the customer in
standardisation? - In standard bodies are only
- manufacturers
- providers
- and since some time also regulators (funded by
tax payers) - The last time I asked I got the answer from a
telco we! - This approach led in the past to
- e.g. ISDN, IN and ATM
12What does the customers want?
- (End-)users want connectivity via any device,
anywhere, at anytime - global mobility
- personal communication
- global reachability
- They also want
- ease of use
- fair prices
- control over additional services
- Skype is providing most of it, but it is also a
walled garden
13What Skype is not providing
- It is not standards based (users dont care)
- It does not provide connectivity (peering) with
other providers via global identifiers - Current IETF activities
- ENUM connectivity with E.164 phone numbers
- SPEERMINT allow interconnect and peering
policies between providers on the Internet - SIP P2P make SIP simpler and easier to use(and
eventually make ENUM and SPEERMINT obsolete -)
14SIP P2P plans to get rid of all optional boxes
Henry Sinnreich
- DNS, ENUM?
- SIP registrar and proxy servers,
- Presence servers
- Application servers
- Announcements, voice mail, media servers,
conference servers - Session border controllers
- Softswitches Local switch emulation, PBX
- Media servers
- Network elements for QoS
- Policy servers
- Network management
- Voice quality monitoring probes
- Network engineering
- System integration
- VoIP network IT (OSS) systems for all the above
The sum of all IMS
.. and it wants to get rid of Skype
