The 3^rd Generation Mobile system is logically implemented on the GSM/GPRS structure through the addition of a new air interface supported by two network nodes, the RNC and the Node B. No inference should be drawn about the physical configuration on an interface from figure 4.1.1.

The CAMEL entities are not shown in figure 4.1.1. For the relationship ship of the CAMEL entities to the core network entities illust2rated above, refer to TS 2.002 [103].

Network architecture for service centralization and continuity is presented in TS 22.002 [103].
