The “five W’s”of context are a good minimal set of necessary context: Who: User and other people in the environment. What: Interpretations of user activity Where: The physical location of the user When: User activity relative changes in time. Why: Understanding the activity of the user. * (1)Customer Context- Customer Need User behavior Usage Trends (1/2) Broadband (higher bandwidth) Increasing use of Internet-based services, demanding more than just Internet access(Applications, Content delivery) Mobility roaming 2.5G/3G/B3G, WLAN, Ultra Wideband (155Mbps) Cellular-WLAN integration Quality of Service Availability, reliability, scalability, security…Flexibility total solutions Terminals and services to be transportable between different networks “One-stop shop”for billing * Service Intelligence convergence Convergence between telecom broadcasting Inter-communication between sophisticated devices Intelligent service location and configuration mechanisms Overall Customer Need Broadband Mobility Home networking QoS /Security Open APIs IPv6 Voice/Data Integration Fixed-Mobile Convergence Telecom/Broadcasting Convergence Converged terminal/appliances (1) Customer Context- User behavior Usage Trends (2/2) * (2) Technology context-evolve toward future network (NGN, Next Generation Network) IPV6 Source: ITU, July, 2003 An unified network--different type of network infrastructure are linked through common protocol.
