Introduction: Some fast facts

Introduction to Kannel
• Kannel: Open Source WAP and SMS Gateway
•
•
•
•
•
•
Officially founded in June 1999 by Wapit Ltd., Helsinki, Finland
Original Architect: Lars Wirzenius room mate of Linus Torvalds
World’s first certified WAP 1.1 gateway by The Open Group
World’s most used SMS gateway est. 800-1000 commercial deployments
Approximately 2000 subscribers to all mailing lists
Extremely fast, reliable and modular pure C with pthreads
• SMS gateway parts
•
•
abstract SMSC protocols to a “known” transport protocol
SMPP 3.4, UCP/EMI 4.0/3.5, CIMD 1.37/2.0, OIS 5.0, SM/ASI, GSM
modems, HTTP APIs  HTTP/1.1
• WAP gateway parts
•
•
WAP 1.2.1 stack implementation WDP, WTP, WSP, WML
Push Proxy Gateway (PPG) i.e. used for MMS notification or SI
Telecom goes Open Source
•
The industry participants start to realize that the “open
standards” model is the way to go
• Learning from the past evolution of IP based protocols (IETF, W3C)
• Numerous standardizing bodies evolve WAP Forum, OMA, OHA
• Again: openness is not “pushing” a standard, it is consensus
• Is Android a successor of the Symbian model, or a competitor?
•
Operators: Giving up control does not mean defeat
• Open systems raise innovation and usage of the network
•
Internet Innovators force the Telecom business to adopt the
“openness model” Google lobbying the FCC
• Open applications, open devices, open services, open networks
Mobile Internet
• Understand what the Mobile Internet is
• It is not a second-dimension system beside the landline Internet
• It’s a subset of it the “overall Internet”
• It’s a network segment, demanding the same services, delivering to
the same users
•
Device capabilities have been driving separation
• i.e. WML vs. full featured HTML for content presentation
•
Standard bodies are pushing back in order to focus on
media convergence
•
Result: IMS
• IP Multimedia Subsystem 3GPP and OMA  open networks?
IP Multimedia Subsystem (IMS)
• Designed to evolve mobile networks beyond GSM
• First 3GPP approach was based on GPRS bearer
• Later abstractive approach for additional bearers
•
Integration with the Internet using IETF protocols
• Session Initiation Protocol (SIP) and way more SIP related protocols
• Diameter, RADIUS, HTTP Digest for AAA
• Real-time Transport Protocol (RTP)
• ENUM
• Again: it’s a subsystem
• Integration to the overall Internet system is achieved widely by using
existing known protocols  gluing horizontally and vertically
IP Multimedia Subsystem (IMS) (2)
• IMS Architecture Overview
Integration Aspects
•
While openness increases vertically layer/stack APIs
• Semantically separation of data and signaling gets more relevant
• A lot more signaling takes place then pure data transmits
• State control and state awareness
• User context while being mobile
• Users have different contexts
• Presence  IMPS (XMPP) vs. SIMPLE
• Location Based Services  who owns the location information?
Status Quo vs. Scenario X
• Mobile Internet market revenues are below potentials
• Technical obstacles and concern network capabilities
• Inadequate marketing and packaging of services
•
Potential Mobile Internet Market Revenue

Last (famous) Words
• Telecom industry has to understand that the Mobile Internet
has to be as openly accessible as the World Wide Web is.
•
Keeping focused on the integration aspects and preserving
openness to the overall system ensures growth.
