Bratislava, Slovakia ◦ PhD student and member of NGNlab.eu initiative } Topic ◦ How to bring presence into the Telco market? ◦ What does the presence protocol landscape offer? ◦ What is a concept for tomorrow with which we can implement already today? 2
} Main objective is integrating communication state into a presence infrastructure } Certain aspects are out of scope ◦ Network service enabler (good, but not yet visible for end-customer) ◦ SIP/XMPP Gateway (no interworking, exists already) ◦ Presence in the IMS (implementations not yet ready) ◦ Yet another presence service on the Telco side “just to catch up” 3
services and offer communication services. ◦ Communication mainly through instant messages ◦ Voice as by-product ◦ Main protocol: XMPP Telecommunication World } Telco’s and smaller providers that have specialized in offering their customers VoIP based telephony ◦ Currently mainly voice services ◦ Growing move towards Presence and Messaging ◦ Main protocol: SIP 4
◦ Basic own infrastructure to serve own customers, who do not yet have the service ◦ Integrate with existing infrastructure to service advanced customers } From voice telephony to communication ◦ Offer voice telephony ◦ Offer messaging + presence ◦ Enhance presence with telephone state information 6
infrastructure ◦ Enhanced SIP proxy that can extract call state information } SIP call states must be converted to XMPP presence information } XMPP as main IM/P protocol 8
Added OpenSIPS with pua_usrloc and pua_dialog module ◦ Added Ejabberd as IM/P server ◦ Deployed and added “XMPP Publisher” } SIP call states of any VoIP infrastructure are available in any XMPP infrastructure 10
years (e.g., in an IMS deployment with more clients), the solution can still be used ◦ Telco IM/P will most likely be based on OMA SIP ◦ Web 2.0 services can still be enriched with the call state information } Mutual benefits for Telco and internet service, the customer is happy as well J 11
still under examination ◦ Identity Management (map SIP/XMPP user) ◦ XMPP means for password-less authentication (third party XMPP service state extension) ◦ Integration of proposed solution into XMPP gateway 13
future, when IMS will be deployed à Solution can co-exist with SIP based presence } Telco integration with internet services is win-win ◦ Telco products are propagated towards internet ◦ Internet services are not competed, but federated ◦ Customer benefits the most More features if he has a presence service Interoperable IM/P service 14
