Figure 10 The All IP vision Figure 11 3GPP migration path 14 IP Terminal Legacy Networks WLAN UMTS BTS Access network Packet switched core network Circuit switched core network Year Gateway Router Mobility Agent RNC Full Service Network ADSL connection between WLAN and the UMTS core network. In UMTS the circuit switched core network will exist for some years in parallel with the packet switched core network. However, eventually the packet switched core network will offer services similar to those in the circuit switched core network, like for example voice and other real time services. When the packet switched technology can offer sufficient QoS also for real time services, the investments in circuit switched technology become superfluous, and in the end all services will be handled by packet transport. Figures 12 and 13 describe different steps along the migration path. The Internet GPRS Support Node is a combination of the SGSN and GGSN node in UMTS, with some additional requirements.

Time IGSN. We find UMTS specific mobility handling internally in the IGSN, and Mobile IP+ will take care of mobility management higher in the hierarchy, between IGSNs and for intersystem mobility. This post 2000 scenario is described by 3GPP [35]. Figure 13 describes another scenario which has been evaluated by Telcordia which is a further integration of IP into the UMTS network. Here the traditional core network as we know it today in UMTS is totally removed and replaced by an IP network. The RNCs are connected to a gateway serving one domain. Mobility locally within one RNC is still handled by UMTS specific signalling. For mobility within the gateway, it is suggested to use Cellular IP, and for mobility outside the domain, Mobile IP+ will be deployed. Telektronikk 1.2001
