Advanced Networking (MSCSP) 17
Telecommunication World– 2G Mobile Communication Systems are in place (GSM, GPRS,
EDGE)– 3G Mobile Systems (UMTS incl. HSDPA) are available– B3G systems (LTE/SAE) are under development– Wireless voice market is saturating– Data traffic is growing– Traditional Telecom Operator and infrastructure provider target the
Internet marketInternet World
– Fixed Internet access is getting common (DSL)– WLAN hot spots are installed at airports, campus areas, coffee shops,
etc.– 802.11a products are standard, 802.11n is establishing– 802.16 (WiMAX) products are available– 802.20 (MBWA) standards approved– Internet Service Providers (ISP) and Internet infrastructure provider
target the mobile market

• is a packet-based network
• provides telecommunication services and more
• uses multiple broadband, QoS-enabled transport technologies
• offers unrestricted access by users to different service providers
• supports generalized mobility
• allows consistent and ubiquitous provision of services to users
• service-related functions are independent from underlying transport-related
technologies
• improved handling and management of middle-boxes

Idea:Access to GSM and GPRS mobile services over unlicensed spectrum (WLAN, Bluetooth)
User View:– Voice and data services– Same mobile identity on GSM and WLAN– Seamless delivery (roaming and handover)– Security equivalent to GSM
Operator view:– Preserves investment in mobile core network infrastructure – Independent of underlying unlicensed spectrum technology (e.g. WLAN,
Bluetooth) – Transparent to existing, standard devices (e.g. access points, routers and
modems) – No impact to operations of GSM/UMTS (e.g. spectrum engineering, cell
planning, …)
