5. © Siemens 5 TISPAN Release 1 Highlights Target date: Summer 2005 Key is adaptation and not modification of IMS QoS is limited to the Access ISDN/PSTN service simulation (in a pure SIP environment) and emulation (e.g. softswitch environment) are both supported as separate subsystems xDSL, WLAN, 3GPP and customer LAN access supported, Cable may be included if someone offers to do the work. Services are offered through external applications, not embedded as capabilities in control protocols Major service capabilities: Conversational, Presence and IM, Content delivery (incl. Video), PSTN/ISDN migration and internet type services

10. © Siemens 10 What does it mean Need to consider layered governamce model:  Layer 1: Network layer infratstructure (root server, DNS, IP and E.164 addresses, protocols, RFID #, MAC, presence ID,.....)  Layer 2: Infra-Services (whois, yellow pages, dispute resolution, multilinguism,....)  Layer 3: Application-related features (spam, illegal and harmful content, privacy, IPR/DRM Required actions:  Identify issues, status, major players and gaps (see e.g. ICC´s issue matrix and gap analysis  allocate new/enhanced tasks to appr. organisations (via WGIG)
