In the future, all telephony services will eventually be delivered over IP due to the low costs and the efficiencies for carriers to maintain a single, unified IP-based telecommunications network. This talk emphasizes the all-IP aspect of wireless and mobile core networks. We first present two platforms, NCTU-SMS and iSMS, that integrate IP networks with mobile short message mechanism. These platforms provide light-weight solutions for quick deployment of added-value data services integrating SMS and IP. Then we introduce mobility and session management evolution from General Packet Radio Service (GPRS) to Universal Mobile Telecommunications System (UMTS). In GPRS, some radio management functions are handled in the core network. These functions have been moved to the radio access network in UMTS. This architectural change results in a clean design that allows radio technology and core network technology to develop independently. We also describe session management functions for IP connection including the Access Point Name (APN) and IP address allocation, tunneling technologies, and QoS management.
